15. Advanced Configuration pmchat The pmchat command acts similar to the standard chat command, but all serial port access is directed via the portmanager. For example, to run a chat script via the portmanager: # pmchat -v -f /etc/config/scripts/port08.chat < /dev/port08 For more information on using chat (and pmchat), consult the UNIX manual pages: http://techpubs.sgi.com/library/tpl/cgibin/getdoc.cgi?coll=linux&db=man&fname=/usr/share/catman/man8/chat.8.html pmusers The pmusers command is used to query the portmanager for active user sessions. For example, to detect which users are currently active on which serial ports: # pmusers This command will output nothing if there are no active users currently connected to any ports. Otherwise, it will respond with a sorted list of usernames per active port: Port 1: user1 user2 Port 2: user1 Port 8: user2 The above output indicates a user named "user1" is actively connected to ports 1 and 2, while "user2" is connected to both ports 1 and 8 With firmware version 3.11 and later, the pmusers command is extended with the --disconnect option, which allows an admin user or root to disconnect console server sessions from the command line. The following connection types can be disconnected: telnet SSH Raw TCP Unauth'ed Telnet You cannot disconnect an RFC2217 session. If the --disconnect option is specified, the pmusers command goes into disconnect mode, where you can specify the users with -u, the ports with -l (by label) or -n (by name). By default, the command will prompt the user before actually disconnecting the matching sessions. This can be overridden with the --no-prompt argument. Example: pmuser sessions: # pmusers --disconnect Disconnect all users from all ports? (y/n) y 5 sessions were disconnected # pmusers --disconnect -u robertw Disconnect user robertw from all ports? (y/n) y 1 session was disconnected # pmusers --disconnect -u robertw -n 5 Disconnect user robertw from port 5 (BranchRouter01)? (y/n) y No sessions were disconnected # pmusers --disconnect -n 5 Disconnect all users from port 5 (BranchRouter01)? (y/n) y 2 sessions were disconnected 244
