Annotation of embedaddon/sudo/INSTALL, revision 1.1.1.2
1.1 misho 1: Sudo installation instructions
2: ==============================
3:
4: Sudo uses a `configure' script to probe the capabilities and type
5: of the system in question. In this release, `configure' takes many
6: more options than it did before. Please read this document fully
7: before configuring and building sudo. You may also wish to read the
8: file INSTALL.configure which explains more about the `configure' script.
9:
10: Simple sudo installation
11: ========================
12:
13: For most systems and configurations it is possible simply to:
14:
15: 0) If you are upgrading from a previous version of sudo
16: please read the info in the UPGRADE file before proceeding.
17:
18: 1) Read the `OS dependent notes' section for any particular
19: "gotchas" relating to your operating system.
20:
21: 2) `cd' to the source or build directory and type `./configure'
22: to generate a Makefile and config.h file suitable for
23: building sudo. Before you actually run configure you
24: should read the `Available configure options' section
25: to see if there are any special options you may want
26: or need.
27:
28: 3) Edit the configure-generated Makefile if you wish to
29: change any of the default paths (alternatively, you could
30: have changed the paths via options to `configure'.
31:
32: 5) Type `make' to compile sudo. If you are building sudo
33: in a separate build tree (apart from the sudo source) GNU
34: make will probably be required. If `configure' did its job
35: properly (and you have a supported configuration) there won't
36: be any problems. If this doesn't work, take a look at the
37: TROUBLESHOOTING file for tips on what might have gone wrong.
38: Please mail us if you have a fix or if you are unable to
39: come up with a fix (address at EOF).
40:
41: 6) Type `make install' (as root) to install sudo, visudo, the
42: man pages, and a skeleton sudoers file. Note that the install
43: will not overwrite an existing sudoers file. You can also
44: install various pieces the package via the install-binaries,
45: install-doc, and install-sudoers make targets.
46:
47: 7) Edit the sudoers file with `visudo' as necessary for your
48: site. You will probably want to refer the sample.sudoers
49: file and sudoers man page included with the sudo package.
50:
51: 8) If you want to use syslogd(8) to do the logging, you'll need
52: to update your /etc/syslog.conf file. See the sample.syslog.conf
53: file included in the distribution for an example.
54:

100:
101: Special features/options:
102: --with-incpath=DIR
103: Adds the specified directory (or directories) to CPPFLAGS
104: so configure and the compiler will look there for include
105: files. Multiple directories may be specified as long as
106: they are space separated.
107: Eg: --with-incpath="/usr/local/include /opt/include"
108:
109: --with-libpath=DIR
110: Adds the specified directory (or directories) to LDFLAGS
111: so configure and the compiler will look there for libraries.
112: Multiple directories may be specified as with --with-incpath.
113:
114: --with-rpath
115: Tells configure to use -Rpath in addition to -Lpath when
116: passing library paths to the loader. This option is on
117: by default for Solaris and SVR4.
118:
119: --with-blibpath[=PATH]
120: Tells configure to construct a -blibpath argument to the
121: loader. If a PATH is specified, it will be used as the
122: base. Otherwise, "/usr/lib:/lib:/usr/local/lib" will be
123: used for gcc and "/usr/lib:/lib" for non-gcc. Additional
124: library paths will be appended as needed by configure.
125: This option is only valid for AIX where it is on by default.
126:
127: --with-libraries=LIBRARY
128: Adds the specified library (or libaries) to SUDO_LIBS and
129: and VISUDO_LIBS so sudo will link against them. If the
130: library doesn't start with `-l' or end in `.a' or `.o' a
131: `-l' will be prepended to it. Multiple libraries may be
132: specified as long as they are space separated.
133:
134: --with-plugindir=PATH
135: Set the directory that sudo looks in to find the policy and I/O
136: logging plugins. Defaults to the libexec dir used by configure.

139: Link with the "electric fence" debugging malloc.
140:
141: --with-bsm-audit
142: Enable support for sudo BSM audit logs on systems that support
143: it. Currently only supported under FreeBSD and Mac OS X.
144:
145: --with-csops
146: Add CSOps standard options. You probably aren't interested in this.
147:
148: --with-devel
149: Configure development options. This will enable compiler warnings
150: and set the Makefile to be able to regenerate the sudoers parser
151: as well as the manual pages.
152:
153: --with-linux-audit
154: Enable audit support for Linux systems. Audits attempts
155: to run a command as well as SELinux role changes.
156:
157: --with-skey[=DIR]
158: Enable S/Key OTP (One Time Password) support. If specified,
159: DIR should contain include and lib directories with skey.h
160: and libskey.a respectively.
161:
162: --with-opie[=DIR]
163: Enable NRL OPIE OTP (One Time Password) support. If specified,
164: DIR should contain include and lib directories with opie.h
165: and libopie.a respectively.
166:
167: --with-SecurID[=DIR]
168: Enable SecurID support. If specified, DIR is directory containing
1.1.1.2 ! misho 169: libaceclnt.a, acexport.h, and sdacmvls.h.
1.1 misho 170:
171: --with-fwtk[=DIR]
172: Enable TIS Firewall Toolkit (FWTK) 'authsrv' support. If specified,
173: DIR is the base directory containing the compiled FWTK package
174: (or at least the library and header files).
175:
176: --with-kerb5[=DIR]
177: Enable Kerberos V support. If specified, DIR is the base
178: directory containing the Kerberos V include and lib dirs.
179: This This uses Kerberos passphrases for authentication but
180: does not use the Kerberos cookie scheme. Will not work for
181: Kerberos V older than version 1.1.
182:
1.1.1.2 ! misho 183: --enable-kerb5-instance=string
! 184: By default, the user name is used as the principal name
! 185: when authenticating via Kerberos V. If this option is
! 186: enabled, the specified instance string will be appended to
! 187: the user name (separated by a slash) when creating the
! 188: principal name.
! 189:
1.1 misho 190: --with-ldap[=DIR]
191: Enable LDAP support. If specified, DIR is the base directory
192: containing the LDAP include and lib directories. Please see
193: README.LDAP for more information.
194:
195: --with-ldap-conf-file=PATH
196: Path to LDAP configuration file. If specified, sudo reads
197: this file instead of /etc/ldap.conf to locate the LDAP server.
198:
199: --with-ldap-secret-file=PATH
200: Path to LDAP secret password file. If specified, sudo uses
201: this file instead of /etc/ldap.secret to read the secret password
202: when rootbinddn is specified in the ldap config file.
203:
204: --with-nsswitch[=PATH]
205: Path to nsswitch.conf or "no" to disable nsswitch support.
206: If specified, sudo uses this file instead of /etc/nsswitch.conf.
207: If nsswitch is disabled but LDAP is enabled, sudo will check
208: LDAP first, then the sudoers file.
209:
210: --with-netsvc[=PATH]
211: Path to netsvc.conf or "no" to disable netsvc.conf support.
212: If specified, sudo uses this file instead of /etc/netsvc.conf
213: on AIX systems.
214:
215: --with-aixauth
216: Enable support for the AIX 4.x general authentication function.
217: This will use the authentication scheme specified for the user
218: on the machine. It is on by default for AIX systems that
219: support it.
220:
221: --with-pam
222: Enable PAM support. This is on by default for Darwin, FreeBSD,
223: Linux, Solaris and HP-UX (version 11 and higher).
224:
225: NOTE: on RedHat Linux and Fedora you *must* have an /etc/pam.d/sudo
226: file install. You may either use the sample.pam file included with
227: sudo or use /etc/pam.d/su as a reference. The sample.pam file
228: included with sudo may or may not work with other Linux distributions.
229: On Solaris and HP-UX 11 systems you should check (and understand)
230: the contents of /etc/pam.conf. Do a "man pam.conf" for more
231: information and consider using the "debug" option, if available,
232: with your PAM libraries in /etc/pam.conf to obtain syslog output
233: for debugging purposes.
234:
235: --with-pam-login
236: Enable a specific PAM session when sudo is given the -i option.
237: This changes the PAM service name when sudo is run with the -i
238: option from "sudo" to "sudo-i", allowing for a separate pam
239: configuration for sudo's initial login mode.
240:
241: --with-AFS
242: Enable AFS support with Kerberos authentication. Should work under
243: AFS 3.3. If your AFS doesn't have -laudit you should be able to
244: link without it.
245:
246: --with-DCE
247: Enable DCE support for systems without PAM. Known to work on
248: HP-UX 9.X, 10.X, and 11.0; other systems may require source
249: code and/or `configure' changes. On systems with PAM support
250: (such as HP-UX 11.0 and higher, Solaris, FreeBSD and Linux), the
251: DCE PAM module (usually libpam_dce) should be used instead.
252:
253: --with-logincap
254: This adds support for login classes specified in /etc/login.conf.
255: It is enabled by default on BSD/OS, Darwin, FreeBSD, OpenBSD and
256: NetBSD (where available). By default, a login class is not applied
257: unless the 'use_loginclass' option is defined in sudoers or the user
258: specifies a class on the command line.
259:
260: --with-bsdauth
261: Enable support for BSD authentication. This is the default
262: for BSD/OS and OpenBSD systems that support it.
263: It is not possible to mix BSD authentication with other
264: authentication methods (and there really should be no need
265: to do so). Note that only the newer BSD authentication API
266: is supported. If you don't have /usr/include/bsd_auth.h
267: then you cannot use this.
268:
269: --with-project
270: Enable support for Solaris project resource limits.
271: This option is only available on Solaris 9 and above.
272:
273: --with-noexec[=PATH]
274: Enable support for the "noexec" functionality which prevents
275: a dynamically-linked program being run by sudo from executing
276: another program (think shell escapes). Please see the
277: "PREVENTING SHELL ESCAPES" section in the sudoers man page
278: for details. If specified, PATH should be a fully qualified
279: path name, e.g. /usr/local/libexec/sudo_noexec.so. If PATH
280: is "no", noexec support will not be compiled in. The default
281: is to compile noexec support if libtool supports building
282: shared objects on your OS.
283:
284: --disable-pam-session
285: Disable sudo's PAM session support. This may be needed on
286: older PAM implementations or on operating systems where
287: opening a PAM session changes the utmp or wtmp files. If
288: PAM session support is disabled, resource limits may not
1.1.1.2 ! misho 289: be updated for the command being run.
1.1 misho 290:
291: --disable-root-mailer
292: By default sudo will run the mailer as root when tattling
293: on a user so as to prevent that user from killing the mailer.
294: With this option, sudo will run the mailer as the invoking
295: user which some people consider to be safer.
296:
297: --disable-setreuid
298: Disable use of the setreuid() function for operating systems
299: where it is broken. Mac OS X has setreuid() but it doesn't
300: really work.
301:
302: --disable-setresuid
303: Disable use of the setresuid() function for operating systems
304: where it is broken (none currently known).
305:
306: --disable-sia
307: Disable SIA support. This is the "Security Integration
308: Architecture" on Digital UNIX. If you disable SIA sudo will
309: use its own authentication routines.
310:
311: --disable-shadow
312: Disable shadow password support. Normally, sudo will compile
313: in shadow password support and use a shadow password if it
314: exists.
315:
316: --with-sudoers-mode=MODE
317: File mode for the sudoers file (octal). Note that if you
318: wish to NFS-mount the sudoers file this must be group
319: readable. Also note that this is actually set in the
320: Makefile. The default mode is 0440.
321:
322: --with-sudoers-uid=UID
323: User id that "owns" the sudoers file. Note that this is
324: the numeric id, *not* the symbolic name. Also note that
325: this is actually set in the Makefile. The default is 0.
326:
327: --with-sudoers-gid=GID
328: Group id that "owns" the sudoers file. Note that this is
329: the numeric id, *not* the symbolic name. Also note that
330: this is actually set in the Makefile. The default is 0.
331:
332: --without-interfaces
333: This option keeps sudo from trying to glean the ip address
334: from each attached ethernet interface. It is only useful
335: on a machine where sudo's interface reading support does
336: not work, which may be the case on some SysV-based OS's
337: using STREAMS.
338:
339: --without-passwd
340: This option excludes authentication via the passwd (or
341: shadow) file. It should only be used when another, alternative,
342: authentication scheme is in use.
343:
344: --with-otp-only
345: This option is now just an alias for --without-passwd.
346:
347: --with-stow
348: Properly handle GNU stow packaging. The sudoers file will
349: physically live in ${prefix}/etc and /etc/sudoers will be
350: a symbolic link.
351:
352: --with-selinux
353: Enable support for role based access control (RBAC) on
354: systems that support SELinux.
355:
356: The following options are also configurable at runtime:
357:
358: --with-long-otp-prompt
359: When validating with a One Time Password scheme (S/Key or
360: OPIE), a two-line prompt is used to make it easier to cut
361: and paste the challenge to a local window. It's not as
362: pretty as the default but some people find it more convenient.
363:
364: --with-logging=TYPE
365: How you want to do your logging. You may choose "syslog",
366: "file", or "both". Setting this to "syslog" is nice because
367: you can keep all of your sudo logs in one place (see the
368: sample.syslog.conf file). The default is "syslog".
369:
370: --with-logfac=FACILITY
371: Determines which syslog facility to log to. This requires
372: a 4.3BSD or later version of syslog. You can still set
373: this for ancient syslogs but it will have no effect. The
374: following facilities are supported: authpriv (if your OS
375: supports it), auth, daemon, user, local0, local1, local2,
376: local3, local4, local5, local6, and local7.
377:
378: --with-goodpri=PRIORITY
379: Determines which syslog priority to log successfully
380: authenticated commands. The following priorities are
381: supported: alert, crit, debug, emerg, err, info, notice,
382: and warning.
383:
384: --with-badpri=PRIORITY
385: Determines which syslog priority to log unauthenticated
386: commands and errors. The following priorities are supported:
387: alert, crit, debug, emerg, err, info, notice, and warning.
388:
389: --with-logpath=PATH
390: Override the default location of the sudo log file and use
391: "path" instead. By default will use /var/log/sudo.log if
392: there is a /var/log dir, falling back to /var/adm/sudo.log
393: or /usr/adm/sudo.log if not.
394:
395: --with-loglen=NUMBER
396: Number of characters per line for the file log. This is only used if
397: you are to "file" or "both". This value is used to decide when to wrap
398: lines for nicer log files. The default is 80. Setting this to 0
399: will disable the wrapping.
400:
401: --with-ignore-dot
402: If set, sudo will ignore '.' or '' (current dir) in $PATH.
403: The $PATH itself is not modified.
404:
405: --with-mailto=USER|MAIL_ALIAS
406: User (or mail alias) that mail from sudo is sent to.
407: This should go to a sysadmin at your site. The default is "root".
408:
409: --with-mailsubject="SUBJECT OF MAIL"
410: Subject of the mail sent to the "mailto" user. The token "%h"
411: will expand to the hostname of the machine.
412: Default is "*** SECURITY information for %h ***".
413:
414: --without-mail-if-no-user
415: Normally, sudo will mail to the "alertmail" user if the user invoking
416: sudo is not in the sudoers file. This option disables that behavior.
417:
418: --with-mail-if-no-host
419: Send mail to the "alermail" user if the user exists in the sudoers
420: file, but is not allowed to run commands on the current host.
421:
422: --with-mail-if-noperms
423: Send mail to the "alermail" user if the user is allowed to use sudo but
424: the command they are trying is not listed in their sudoers file entry.
425:
426: --with-passprompt="PASSWORD PROMPT"
427: Default prompt to use when asking for a password; can be overridden
428: via the -p option and the SUDO_PROMPT environment variable. Supports
429: the "%H", "%h", "%U" and "%u" escapes as documented in the sudo
430: manual page. The default value is "Password:".
431:
432: --with-badpass-message="BAD PASSWORD MESSAGE"
433: Message that is displayed if a user enters an incorrect password.
434: The default is "Sorry, try again." unless insults are turned on.
435:
436: --with-fqdn
437: Define this if you want to put fully qualified hostnames in the sudoers
438: file. Ie: instead of myhost you would use myhost.mydomain.edu. You may
439: still use the short form if you wish (and even mix the two). Beware
440: that turning FQDN on requires sudo to make DNS lookups which may make
441: sudo unusable if your DNS is totally hosed. Also note that you must
442: use the host's official name as DNS knows it. That is, you may not use
443: a host alias (CNAME entry) due to performance issues and the fact that
444: there is no way to get all aliases from DNS.
445:
446: --with-timedir=PATH
447: Override the default location of the sudo timestamp directory and
448: use "path" instead.
449:
450: --with-sendmail=PATH
451: Override configure's guess as to the location of sendmail.
452:
453: --without-sendmail
454: Do not use sendmail to mail messages to the "mailto" user.
455: Use only if don't run sendmail or the equivalent.
456:
457: --with-umask=MASK
458: Umask to use when running the root command. The default is 0022.
459:
460: --without-umask
461: Preserves the umask of the user invoking sudo.
462:
463: --with-umask-override
464: Use the umask specified in sudoers even if it is less restrictive
465: than the user's. The default is to use the intersection of the
466: user's umask and the umask specified in sudoers.
467:
468: --with-runas-default=USER
469: The default user to run commands as if the -u flag is not specified
470: on the command line. This defaults to "root".
471:
472: --with-exempt=GROUP
473: Users in the specified group don't need to enter a password when
474: running sudo. This may be useful for sites that don't want their
475: "core" sysadmins to have to enter a password but where Jr. sysadmins
476: need to. You should probably use NOPASSWD in sudoers instead.
477:
478: --with-passwd-tries=NUMBER
479: Number of tries a user gets to enter his/her password before sudo logs
480: the failure and exits. The default is 3.
481:
482: --with-timeout=NUMBER
483: Number of minutes that can elapse before sudo will ask for a passwd
484: again. The default is 5, set this to 0 to always prompt for a password.
485:
486: --with-password-timeout=NUMBER
487: Number of minutes before the sudo password prompt times out.
488: The default is 5, set this to 0 for no password timeout.
489:
490: --without-tty-tickets
491: By default, sudo uses a different ticket file for each user/tty combo.
492: With this option disabled, a single ticket will be used for all
493: of a user's login sessions.
494:
495: --with-insults
496: Define this if you want to be insulted for typing an incorrect password
497: just like the original sudo(8). This is off by default.
498:
499: --with-insults=disabled
500: Include support for insults but disable them unless explicitly
501: enabled in sudoers.
502:
503: --with-all-insults
504: Include all the insult sets listed below. You must either specify
505: --with-insults or enable insults in the sudoers file for this to
506: have any effect.
507:
508: --with-classic-insults
509: Uses insults from sudo "classic." If you just specify --with-insults
510: you will get the classic and CSOps insults. This is on by default if
511: --with-insults is given.
512:
513: --with-csops-insults
514: Insults the user with an extra set of insults (some quotes, some
515: original) from a sysadmin group at CU (CSOps). You must specify
516: --with-insults as well for this to have any effect. This is on by
517: default if --with-insults is given.
518:
519: --with-hal-insults
520: Uses 2001-like insults when an incorrect password is entered.
521: You must either specify --with-insults or enable insults in the
522: sudoers file for this to have any effect.
523:
524: --with-goons-insults
525: Insults the user with lines from the "Goon Show" when an incorrect
526: password is entered. You must either specify --with-insults or
527: enable insults in the sudoers file for this to have any effect.
528:
529: --with-pc-insults
530: Replace politically incorrect insults with less objectionable ones.
531:
532: --with-secure-path[=PATH]
533: Path used for every command run from sudo(8). If you don't trust the
534: people running sudo to have a sane PATH environment variable you may
535: want to use this. Another use is if you want to have the "root path"
536: be separate from the "user path." You will need to customize the path
537: for your site. NOTE: this is not applied to users in the group
538: specified by --with-exemptgroup. If you do not specify a path,
539: "/bin:/usr/ucb:/usr/bin:/usr/sbin:/sbin:/usr/etc:/etc" is used.
540:
541: --without-lecture
542: Don't print the lecture the first time a user runs sudo.
543:
544: --with-editor=PATH
545: Specify the default editor path for use by visudo. This may be a
546: single path name or a colon-separated list of editors. In the latter
547: case, visudo will choose the editor that matches the user's VISUAL
548: or EDITOR environment variables or the first editor in the list that
549: exists. The default is the path to vi on your system.
550:
551: --with-env-editor
552: Makes visudo consult the VISUAL and EDITOR environment variables before
553: falling back on the default editor list (as specified by --with-editor).
554: Note that this may create a security hole as it allows the user to
555: run any arbitrary command as root without logging. A safer alternative
556: is to use a colon-separated list of editors with the --with-editor
557: option. visudo will then only use the VISUAL or EDITOR variables
558: if they match a value specified via --with-editor.
559:
560: --with-askpass=PATH
561: Set PATH as the "askpass" program to use when no tty is
562: available. Typically, this is a graphical password prompter,
563: similar to the one used by ssh. The program must take a
564: prompt as an argument and print the received password to
565: the standard output.
566:
567: --with-iologdir[=DIR]
568: By default, sudo stores I/O log files in either /var/log/sudo-io,
569: /var/adm/sudo-io, or /usr/log/sudo-io. If this option is
570: specified, I/O logs will be stored in the indicated directory
571: instead.
572:
573: --disable-authentication
574: By default, sudo requires the user to authenticate via a
575: password or similar means. This options causes sudo to
576: *not* require authentication. It is possible to turn
577: authentication back on in sudoers via the PASSWD attribute.
578:
579: --disable-root-sudo
580: Don't let root run sudo. This can be used to prevent people from
581: "chaining" sudo commands to get a root shell by doing something
582: like "sudo sudo /bin/sh".
583:
584: --enable-gss-krb5-ccache-name
585: Use the gss_krb5_ccache_name() function to set the Kerberos
586: V credential cache file name. By default, sudo will use
587: the KRB5CCNAME environment variable to set this. While
588: gss_krb5_ccache_name() provides a better API to do this it
589: is not supported by all Kerberos V and SASL combinations.
590:
591: --enable-log-host
592: Log the hostname in the log file.
593:
594: --enable-noargs-shell
595: If sudo is invoked with no arguments it acts as if the "-s" flag had
596: been given. That is, it runs a shell as root (the shell is determined
597: by the SHELL environment variable, falling back on the shell listed
598: in the invoking user's /etc/passwd entry).
599:
600: --enable-shell-sets-home
601: If sudo is invoked with the "-s" flag the HOME environment variable
602: will be set to the home directory of the target user (which is root
603: unless the "-u" option is used). This option effectively makes the
604: "-s" flag imply "-H".
605:
606: --disable-path-info
607: Normally, sudo will tell the user when a command could not be found
608: in their $PATH. Some sites may wish to disable this as it could
609: be used to gather information on the location of executables that
610: the normal user does not have access to. The disadvantage is that
611: if the executable is simply not in the user's path, sudo will tell
612: the user that they are not allowed to run it, which can be confusing.
613:
614: --enable-zlib[=location]
615: Enable the use of the zlib compress library when storing
616: I/O log files. If specified, location is the base directory
617: containing the zlib include and lib directories. The special
618: values "system" and "builtin" can be used to indicate that
619: the system version of zlib should be used or that the version
620: of zlib shipped with sudo should be used instead.
621: If this option is not specified, configure will use the
622: system zlib if it is present.
623:
624: --disable-zlib
625: Disable the use of the zlib compress library when storing
626: I/O log files.
627:
628: --enable-warnings
629: Enable compiler warnings when building sudo with gcc.
630:
631: --enable-werror
632: Enable the -Werror compiler option when building sudo with gcc.
633:
634: --enable-admin-flag
635: Enable the creation of an Ubuntu-style admin flag file
636: the first time sudo is run.
637:
638: --disable-env-reset
639: Disable environment resetting. This sets the default value
640: of the "env_reset" Defaults option in sudoers to false.
641:
642: --enable-nls[=location]
643: Enable natural language support using the gettext() family
644: of functions. If specified, location is the base directory
645: containing the libintl include and lib directories. If
646: this option is not specified, configure will look for the
647: gettext() family of functions in the standard C library
648: first, then check for a standalone libintl (linking with
649: libiconv as needed).
650:
651: --disable-nls
652: Disable natural language support. By default, sudo will
653: use the gettext() family of functions, if available, to
654: implement messages in the invoking user's native language.
655: Note that translations do not exist for all languages.
656:
657: Shadow password and C2 support
658: ==============================
659:
660: Shadow passwords (also included with most C2 security packages) are
661: supported on most major platforms for which they exist. The
662: `configure' script will attempt to determine if your system can use
663: shadow passwords and include support for them if so. Shadow password
664: support is now compiled in by default (it doesn't hurt anything if you
665: don't have them configured). To disable the shadow password support,
666: use the --disable-shadow option to configure.
667:
668: Shadow passwords are known to work on the following platforms:
669:
670: SunOS 4.x
671: Solaris 2.x
672: HP-UX >= 9.x
673: Ultrix 4.x
674: Digital UNIX
675: IRIX >= 5.x
676: AIX >= 3.2.x
677: Linux
678: SCO >= 3.2.2
679: Pyramid DC/OSx
680: UnixWare
681: SVR4 (and variants using standard SVR4 shadow passwords)
682: 4.4BSD based systems (including OpenBSD, NetBSD, FreeBSD, and Mac OS X)
683: Systems using SecureWare's C2 security.
684:
685: OS dependent notes
686: ==================
687:
688: Linux:
689: PAM and LDAP headers are not installed by default on most Linux
690: systems. You will need to install the "pam-dev" package if
691: /usr/include/security/pam_appl.h is not present on your system.
692: If you wish to build with LDAP support you will also need the
693: openldap-devel package.
694:
695: Versions of glibc 2.x previous to 2.0.7 have a broken lsearch().
696: You will need to either upgrade to glibc-2.0.7 or use sudo's
697: version of lsearch(). To use sudo's lsearch(), comment out
698: the "#define HAVE_LSEARCH 1" line in config.h and add lsearch.o
699: to the LIBOBJS line in the Makefile.
700:
701: If you are using a Linux kernel older than 2.4 it is not possible
702: to access the sudoers file via NFS. This is due to a bug in
703: the Linux client-side NFS implementation that has since been
704: fixed. There is a workaround on the sudo ftp site, linux_nfs.patch,
705: if you need to NFS-mount sudoers on older Linux kernels.
706:
707: Solaris 2.x:
708: You need to have a C compiler in order to build sudo. Since
709: Solaris 2.x does not come with one by default this means that
710: you either need to install the Sun Studio compiler suite,
711: available for free from www.sun.com, or have a copy of the GNU
712: C compiler (gcc) which is distributed on the Solaris Companion
713: CD. You can also get them from various places on the net,
714: including http://www.sunfreeware.com/
715: NOTE: sudo will *not* build with the sun C compiler in BSD
716: compatibility mode (/usr/ucb/cc). Sudo is designed to
717: compile with the standard C compiler (or gcc) and will
718: not build correctly with /usr/ucb/cc. You can set the
719: CC environment variable to the non-ucb compiler when
720: running `configure' if it is not the first cc in your
721: path. Some sites link /usr/ucb/cc to gcc; configure will
722: not notice this and still refuse to use /usr/ucb/cc, so
723: make sure gcc is also in your path if your site is setup
724: this way.
725: Also: Older versions of Solaris come with a broken syslogd.
726: If you have having problems with sudo logging you should
727: make sure you have the latest syslogd patch installed.
728: This is a problem for Solaris 2.4 and 2.5 at least.
729:
730: Mac OS X:
731: The pseudo-tty support in the Mac OS X kernel has bugs related
732: to its handling of the SIGTSTP, SIGTTIN and SIGTTOU signals.
733: It does not restart reads and writes when those signals are
734: delivered. This may cause problems for some commands when I/O
735: logging is enabled. The issue has been reported to Apple and
736: is bug id #7952709.
737:
738: HP-UX:
739: The default C compiler shipped with HP-UX is not an ANSI compiler.
740: You must use either the HP ANSI C compiler or gcc to build sudo.
741: Binary packages of gcc are available from http://hpux.connect.org.uk/.
742:
743: To prevent PAM from overriding the value of umask on HP-UX 11,
744: you will need to add a line like the following to /etc/pam.conf:
745:
746: sudo session required libpam_hpsec.so.1 bypass_umask
747:
1.1.1.2 ! misho 748: If every command run via sudo displays information about the last
! 749: successful login and the last authentication failure you should
! 750: make use an /etc/pam.conf line like:
! 751:
! 752: sudo session required libpam_hpsec.so.1 bypass_umask bypass_last_login
! 753:
1.1 misho 754: Digital UNIX:
755: By default, sudo will use SIA (Security Integration Architecture)
756: to validate a user. If you want to use an alternative authentication
757: method that does not go through SIA, you need to use the
758: --disable-sia option to configure. If you use gcc to compile
759: you will get warnings when building interfaces.c. These are
760: harmless but if they really bug you, you can edit
761: /usr/include/net/if.h around line 123, right after the comment:
762: /* forward decls for C++ */
763: change the line:
764: #ifdef __cplusplus
765: to:
766: #if defined(__cplusplus) || defined(__GNUC__)
767: If you don't like the idea of editing the system header file
768: you can just make a copy in gcc's private include tree and
769: edit that.
770:
771: AIX 3.2.x:
772: I've had various problems with the AIX C compiler producing
773: incorrect code when the -O flag was used. When optimization
774: is not used, the problems go away. Gcc does not appear
775: to have this problem.
776:
777: SCO ODT:
778: You'll probably need libcrypt_i.a available via anonymous ftp
779: from sosco.sco.com. The necessary files are /SLS/lng225b.Z
780: and /SLS/lng225b.ltr.Z.
781:
782: SunOS 4.x:
783: SunOS does not ship with an ANSI C compiler. You will need to
784: install an ANSI compiler such as gcc to build sudo.
785:
786: The /bin/sh shipped with SunOS blows up while running configure.
787: You can work around this by installing bash or zsh. If you
788: have bash or zsh in your path, configure will use it instead
789: automatically.
790:
791: ULTRIX 4.x:
792: ULTRIX does not ship with an ANSI C compiler. You will need to
793: install an ANSI compiler such as gcc to build sudo.
794:
795: The /bin/sh shipped with ULTRIX blows up while running configure.
796: You can work around this by installing bash or zsh. If you
797: have bash or zsh in your path, configure will use it instead
798: automatically.
799:
800: ULTRIX ships with the 4.2BSD syslog(3) which does not
801: allow things like logging different facilities to different
802: files, redirecting logs to a single loghost and other niceties.
803: You may want to just grab and install:
804: ftp://www.sudo.ws/pub/sudo/misc/jtkohl-syslog-complete.tar.gz
805: (available via anonymous ftp) which is a port if the 4.3BSD
806: syslog/syslogd that is backwards compatible with the Ultrix version.
807: I recommend it highly. If you do not do this you probably want
808: to run configure with --with-logging=file
