Table 13. Help commands (continued) Command help_advanced ping ssh ssh_forget_host top Purpose Displays the help for more advanced commands, which are used for debugging. [-c count] [-i interval] [-n] [-s packetsize] [-W waittime] - Sends ICMP ECHO_REQUEST packets to a network host. If it is "gw", then the next hop gateway for the default route is used. It works like the ping command on other operating systems. Press + to stop the ping process or halt any other command in CROSH. [optional args...] - Starts the ssh subsystem if invoked without any arguments. "ssh ", "ssh ", "ssh< user>@". or "ssh @ " connect without entering the subsystem Removes a host from the list of known ssh hosts. This command displays a menu of known hosts and prompts for the host to forget. Sets the chaps debug logging level. No arguments start verbose logging Table 14.

systems. Press
<Clrt> + <C>
to stop the ping process or halt
any other command in CROSH.
ssh
[optional args...] — Starts the ssh subsystem if invoked
without any arguments. "ssh <user> <host>", "ssh
<user> <host> <port>", "ssh< user>@<host>". or "ssh
<user>@<host> <port>" connect without entering the
subsystem
ssh_forget_host
Removes a host from the list of known ssh hosts. This
command displays a menu of known hosts and prompts for
the host to forget.

Sets the chaps debug logging level. No arguments start
verbose logging
Table 14. Advanced help command
