Cisco IOS: Show incoming Telnet sessions
Solution 1
You're looking for:
show users
(or like most would type sh users
)
Solution 2
show sessions
will display outgoing connections from your switch/router to other devices.
show users
will display incoming connections to the vty interfaces (ssh/telnet...) of your switch/router.
So i think you need show users
here.
Solution 3
Other useful ways to see who is connected would include who
, show line
and show ssh
. For detailed info on connections you can use show tcp
.
Solution 4
Many IOS versions also support the who and where commands. Who displays the same output as show users. Where displays the same output as show sessions

According to
show ?
theshow sessions
command is supposed to showInformation about Telnet connections
. Although I'm connected, the sessions does not show up. Both devices run Cisco IOS. How can I look up current Telnet sessions?On the router running the Telnet server:
Router2#debug telnet Incoming Telnet debugging is on Router2# Router2# Oct 25 13:34:59.063: Telnet226: 1 1 251 1 Oct 25 13:34:59.063: TCP226: Telnet sent WILL ECHO (1) Oct 25 13:34:59.063: Telnet226: 2 2 251 3 Oct 25 13:34:59.063: TCP226: Telnet sent WILL SUPPRESS-GA (3) Oct 25 13:34:59.063: Telnet226: 80000 80000 253 24 Oct 25 13:34:59.063: TCP226: Telnet sent DO TTY-TYPE (24) Oct 25 13:34:59.063: Telnet226: 10000000 10000000 253 31 Oct 25 13:34:59.063: TCP226: Telnet sent DO WINDOW-SIZE (31) Oct 25 13:34:59.071: TCP226: Telnet received DO SUPPRESS-GA (3) Oct 25 13:34:59.075: TCP226: Telnet received WILL TTY-LOCATION (23) (refused) Oct 25 13:34:59.079: TCP226: Telnet sent DONT TTY-LOCATION (23) Oct 25 13:34:59.083: TCP226: Telnet received WILL TTY-SPEED (32) (refused) Oct 25 13:34:59.087: TCP226: Telnet sent DONT TTY-SPEED (32) Oct 25 13:34:59.091: TCP226: Telnet received WILL WINDOW-SIZE (31) Oct 25 13:34:59.091: TCP226: Telnet received WILL LOCAL-FLOW (33) Oct 25 13:34:59.095: TCP226: Telnet sent DO LOCAL-FLOW (33) Oct 25 13:34:59.099: Telnet226: Sent SB 33 0 Oct 25 13:34:59.099: TCP226: Telnet received DO ECHO (1) Oct 25 13:34:59.103: TCP226: Telnet received WONT TTY-TYPE (24) Oct 25 13:34:59.103: TCP226: Telnet sent DONT TTY-TYPE (24) Oct 25 13:34:59.103: Telnet226: recv SB NAWS 80 24 Oct 25 13:34:59.107: TCP226: Telnet received WONT TTY-LOCATION (23) Oct 25 13:34:59.115: TCP226: Telnet received WONT TTY-SPEED (32) Router2# Router2# Router2#show sessions % No connections open Router2#
On the router connected to the Telnet server:
