SSHD-CHECK-CONF(5)

NAME
sshd-check-conf - check what your configuration allows or denies based on incoming user and/or host name.

SYNOPSIS
sshd-check-conf [-d debug_level ] [-v ] [-V ] [-h ] [-f config_file ] [[user@]host ... ]

DESCRIPTION

Sshd-check-conf checks how sshd2 will react to an incoming user, based on the user name and the remote host name given as parameters. Currently, the parameters AllowHosts, DenyHosts, AllowSHosts, DenySHosts, AllowUsers, DenyUsers, AllowGroups, DenyGroups, ChrootUsers, ChrootGroups, AllowTcpForwardingForUsers, DenyTcpForwardingForUsers, AllowTcpForwardingForGroups , and DenyTcpForwardingForGroups are checked.

OPTIONS

-d debug_level_spec
    Debug mode. The debugging level is either a number or a comma-separated list of assignments "ModulePattern=debug_level".

-v  Enable verbose mode. Display verbose debugging messages. Equal to '-d 2'.

-V  Display version string.

-h  Display a short help on command-line options.

-f configuration_file
    Specifies the name of the configuration file. The default is /usr/local/etc/ssh2/sshd2_config or $HOME/.ssh2/sshd2_config, depending on who is running the program, root or normal user.

BEHAVIOUR
Any non-options presented on the command line will be regarded as [user@]host patterns (that is, the user part is optional). If the host part is a valid IP address, it is looked up from DNS. Otherwise, it is interpreted as a host name and the corresponding IP addresses will be queried from DNS. You can specify multiple patterns on the command line. If no patterns are specified on the command line, sshd-check-conf will go into interactive mode, where the patterns can be given one at a time, and they will be checked. You may also specify one command in interactive mode, "dump". This command dumps the configuration (with subconfigs amended) for the previous pattern given.
