Don't see active telnet or SSH sessions

frnkblk — Thu, 12 Dec 2024 01:30:08 GMT

Why don't I see my telnet and SSH sessions showing here?

telnet@router#show telnet
Telnet server status: Enabled
Telnet connections:
telnet@router#show ip ssh sessions
SSH server status: Enabled
SSH connections:
SSH connections (inbound):
SSH connections (outbound):
telnet@router#show manager sessions
SSH connections:
SSH connections (inbound):
SSH connections (outbound):
telnet@router#

I do see them here:
telnet@router#show ip tcp connections

I'm running SPR09010f.bin on an ICX7450 stack.

if 9 supports it:

sh who
(or for ssh "sh ip ssh sessions)

no idea for telnet, don't think i've used that the past 5 years or so

Hi frnkblk,

With respect to the query, please do check once with "show who" command, that should list all ssh/telnet/console sessions to the unit.

Let us know if the same helps !

Regards,
Joshua

I can't log into the original router rihgt now, but when I do a "show who" on another 7450 running switch code (SPS09010c.bin) it doesn't work, either.

I'm SSH'd in via the mgmt port -- I see a logged in user on the serial port (that's fine), but not me on SSH

SSH@router>show who
Console connections (by unit number):
1 ESTABLISHED, user is admin
, privilege super-user

Can you try 9010j_cd6? I would think we would have a ton of cases if there was a blatant bug like this still out there. If you see it in 9010j_cd6, please open a case for a formal investigation.

I agree, it does seem like strange that not more people are seeing this.

We're planning to upgrade to 9010j_cd6 -- I'll update this group with the results once that's done.

I just completed the upgrade -- no change:

So after attempting to use the Ethernet management port, and then switching back, it now works, showing the active SSH and telnet session I have in place.

telnet@router#show ip ssh sessions
SSH server status: Enabled
SSH connections:
SSH connections (inbound):
1 ESTABLISHED client ip address 192.168.0.8, user is fbulk, privilege super-user, using vrf default-vrf
SSH connections (outbound):
telnet@router#show telnet
Telnet server status: Enabled
Telnet connections:
Telnet connections (inbound):
1 ESTABLISHED , client ip address 192.168.0.8, user is fbulk, privilege is super-user, using vrf default-vrf
