Hello, I'm trying to enable ssh access on the inside interface. It's not working and I get this error message
Unable to configure service on port 22, on interface 'INSIDE'. This port is currently in use by another feature. I did a show asp table sockets and it seems something else is listening to port tcp/22. What other service is listening on port 22. I tried it on other interfaces there it is working.
Result of the command: "show asp table socket" (172.16.2.25 is my INSIDE interface)
Protocol Socket Local Address Foreign Address State
SSL 000023ff 172.16.2.25:443 0.0.0.0:* LISTEN
TCP 0000426f 172.16.2.25:22 0.0.0.0:* LISTEN
thanks

Hi Alex,
Can you provide the output of :
show run | inc inside
There's got to be some other service using the inside interface ip, and thats y you are unable to ssh to it.
Thanks,
Varun

This is
Symptom:
After upgrade the ASA to 8.4(1), ssh to one or more interfaces are failing.
Removing and re-adding the SSH configuration results in the following error
message:
ciscoasa(config)# ssh 0 0 outside
ERROR: Unable to configure service on port 22, on interface 'outside'. This
port is currently in use by another feature
Usage: [no] ssh {| }
[no] ssh timeout
[no] ssh version 1|2
[no] ssh scopy enable
show ssh [sessions []]
ssh disconnect
show running-config [all] ssh
clear configure ssh
Conditions:
Access via ASDM or telnet are unaffected. SSH still may work to other
interfaces, but is failing to a specific interface.
Workaround:
Reload the ASA.
Resolved in
008.004(002) 008.004(001.002)
Upgrade to get the fix.

I met the same issue and our ASA version is 9.16(2)14.
Someone in another discussion suggested a reboot and it helped. So I suppose the problem is related to the current state of the firewall where it is not possible to add another ssh users on some interface. I was able to add ssh user at different interface but not at outside interface. Some check prevents it. The reason is unknown.

Seeing the same thing with 9.16(2)14.
