GSP console, max number of telnet sessions reached

[pat hayes]

We have an rp4440 running HP-UX 11i. When we try to telnet to our GSP console, which has it's own IP address, we receive the message "sorry, the maximum number of active telnet sessions has been reached". This must be a different parameter setting than nstrtel because (mercifully) we are still able to telnet to the machine itself. Any ideas how I can bump up the telnet session limit for GSP, or how I can get rid of old sessions? As far as I'm aware, there is no one currently actively telnet-ed to GSP. thanks.

I think at this point, you have to go attach a physical console to the server and hit ctrl-b to get to the GSP prompt and issue a "WHO" command to see who is on the GSP lan port if you are interested or just kill the connection by DI(sconnect) command.

I am not sure how many simultaneous connections are allowed on GSP lan or if this parameter can be modified though.

Hi Pat,

From the command (CM) menu you use the disable (DI) command as follows:

DI -telnet

This will *not* disable future telnets - it just bumps *all* telnet users from the MP

You can use the WHO command ahead of this to see the actual telnet users are.

HTH,

I just checked a 4440 here and the MP seems to be the same as on higher end models so in theory it should allow up to 16 connections. I might be mistaken.

Try getting on it with a serial console, the type "CM", "SA", and confirm that telnet access is at least enabled.

As an alternative connect to it with a web browser, in case the web console is active.

Good luck

Hi Pat,

there is a maximum of 32 sessions in parallel. You can't change this. But (as mentioned) you can disconnect active sessions (DI).

I was able to get on via a web browser, and did a who which showed several old connections, so I did the di -telnet and enter a Y to confirm and everything just hung up. I can't ctrl-b out of it, nor can I reach it the console via a web browser again and the telnet still gives the max number of telnet sessions reached. Any other suggestions? I've read about the GSP reset, is that my only option? What exactly will I lose if i do that? thanks.

first check, if the GSP is still running fine:

stty +queryGSP
What is the result?
You can reset the GSP while the OS is running without problems. First choice:

stty +resetGSP
or you log on with a serial attached console, press B, type in your current user/pass, go to the command menu (CM), diagnostics (XD) and reset (R).

[pat hayes]

the result of

stty +queryGSP < /dev/GSPdiag1

is

GSP is functional.

But, the result of

stty +resetGSP < /dev/GSPdiag1

is

GSP reset failed

And, I still get the max number of telnet sessions message when I try to telnet, or a hung console after login when I browse to it.

Pat, the best thing is to connect a serial console to the system and check the SA value. This can enable/disable telnet.
see CM>HE SA for more information. Also check the ip settings, if netmask and gateway are correct. But telnet maybe disabled.

BTW, it's always a good idea to have the latest firmware for the GSP (it's called MP or even iLO now). You should have at least version E.03.15. You can install this as a patch (reboot required).
Find out the current version by typing HE at the MP prompt and post the first lines, please.
Did you connect with serial console and did a gsp reset with XD followed by R? If you don't have, you may also push the MP soft reset button on the rear, but only once and a short time of about 3 seconds. If you press longer, you'll probably reset the LAN settings to the default values.
