1. NAME

pam_abl - query or purge the databases used by the pam_abl module.

2. SYNOPSIS

pam_abl [OPTION] [CONFIG]

3. DESCRIPTION

Provides a non-pam interface to the infomration stored in the pam_abl module databases. CONFIG is the name of the pam_abl config file (default: /etc/security/pam_abl.conf). The config file is read to discover the names of the pam_abl databases, the rules that control purging of old data from them and commands to run when a user or host switches state.

4. OPTIONS

4.1. MAINTENANCE

-h, --help
See this message.
-p, --purge
Purge databases according to purge rules in config.
-r, --relative
Display times relative to now.
-v, --verbose
Verbose output.

4.2. NON-PAM INTERACTION

-f, --fail
Fail user or host.
-w, --whitelist
Perform whitelisting (remove from blacklist, does not provide immunity).
-c, --check
Check status. Returns non-zero if currently blocked Prints name: status if verboseness is specified. If more than one host or user is given, checks only the first host/user pair.
-s, --service
Operate in context of specified service. Defaults to none.
-U, --user
Operate on user (wildcards are ok for whitelisting).
-H, --host
Operate on host (wildcards are ok for whitelisting).

If you specified commands to run in your configuration, those commands will try to run if the host or user switches state (blocked <→ clear) since the last time it was checked. The command will only be able to run, however, if you supply enough information to fill in the substitutions in the command. For instance, if your host_clr_command uses the %s parameter, you will need to specify the service with -s in order for the command to actually run.

5. EXAMPLES

Obtain a list of failed hosts and users:

$ pam_abl

Obtain a full list of failures listing times relative to now:

$ pam_abl -rv $ pam_abl --relative --verbose

Purge old data:

$ pam_abl -p $ pam_abl --purge

Unblock all example.com, somewhere.com hosts:

$ pam_abl -w -H *.example.com -H \*.somewhere.com

Fail the host badguy.com and the user joe:

$ pam_abl -f -H badguy.com -U joe

Check whether joe is currently allowed to use your neato service from somehost, running the necessary commands if he switches state:

$ pam_abl -c -U joe -H somehost -s neato
