Looking for commands to identify any https, ssh, or telnet sessions currently active on a PIX and on an ASA. I would like to know all available information about the current connections, such as the IP address of the connected device, username used for authenticaion, the duration of the connection, and idle time.
There's no single command that produces all this info, but I think you can find most or all of it using:
show ssh sessions
show asdm sessions
sh conn long all | i Identity.*/22
sh conn long all | i Identity.*/23
sh conn long all | i Identity.*/443 (but this may include webvpn sessions in addition to ASDM, if both are running on the same port).
