K-Series Console access via network terminal server

[Dan Matlock_1]

Question: I have some K-series servers connected through a IR-8020 terminal server, and all works well except: I can't seem to figure out the magic to get the ^b function to work. If I initiate the seesion from a HP console, then telnet through the terminal server to the target then it works. I assume it has to do w/the keyboard mapping. Does anyone know how to resolve this issue?

Thanks in advance,

Later servers GSP cards have their own network interface. This would allow you to set them up on a Cat 5 cable with an ip address and telnet in directly to the console.

I'm not aware of what kind if connections are available on a K class server.

You may want to look at the interface and see if this an alternative.

Not every device can be a console.

stty -a and see if you can get the settings to match a working console.

It might also be the TERM variable.

Hi,
The K-Class has ^B function will work when the SPU key position is in SERVICE.
^B will be accesile only from console port (or Remote console if enabled with line access module - LAM).
There is no LAN interface in K-Class systems for console access.
I am wondering how you are doing telnet to a console port (which is RS-232).

I have no knowledge on IR-8020 terminal server.

Verify you get ^B from when you connect directly a standard HP serial console (also make sure your key position in SERVICE).

Thanks for all of the interest. Yes Direct connect HP console ^B works, as well as telnet from a HP system at the console to another server via terminal server. The terminal server I am using (bought before my time) is from MRV.com = IR-8020. You connect to HP's console directly to a port, and then simply telnet (termsrv ip) and port (2100 = port 1). I then have access via telnet to the console, but again from a windows initiated telnet TERM and/or keyboard mapping does work for the ^B. Anyway thanks, and I'll keep trying. p.s. YES our newer servers have direct connect network to the MP.

The K-series have no GSP, just a simple terminal interface. Your problem is not likely a keyboard mapping problem at all, but a terminal server that is trapping CTLR-B (and perhaps other codes). Some terminal servers (not KVM but serial terminals) will have a method to configure special characters but most modern servers have no reserved characters other than the telnet break code (CTRL-]) which is needed to return back ti the server's main menu.

Look through the terminal server's tech ref manual or contact the manufacturer about special codes that are blocked or trapped by the server. I use a Cyclades server with many K460's, about 10 network routers/switches, a SAN, etc. CTRL-B works great.

I have the info I need to resolve/work around the issue. Thanks.
