No login prompt

[Carlo Henrico_1]

Hi All

One of my production servers (HP-UX 11.0 on a RP2470) was giving no login prompt via telnet or the console. After a reset via GSP it came right temporarily. After about 12 hours or so it did the same. After another reset I cleared out the wtmp (backed it up first!), and now all seems fine.

Any ideas what causes this and how do I prevent it in future?

Thanks

Hi,

Was it giving "GSP Write access failed" when tried to telnet to GSP IP.If yes it is a GSP hangup which usually occurs. The only remedy is to reset GSP through

#stty +resetGSP
It can not be avoided.

No, no GSP errors, only no login prompt via telnet or the console.

Hi,

It means you reseted the machine itself not GSP. What was the error when tried to login through telnet or on console ? Was anything logged to /var/adm/syslog/syslog.log ?

As I said "...reset via GSP ...". In other words, I rebooted the server using GSP commands, not the GSP. I could not access the server at all through telnet or console, it just gave me a blank screen, no login prompt and no errors.

Any such problems first take a look in /var/adm/syslog/syslog.log

There was nothing in the syslog, neither time.

Thanks

Hi,

please check which version of "s700_800 11.00 telnet kernel and telnetd(1M) patch" is running on your server. There was an issue where utmp/utmpx could be corrupted by telnetd. The last version is PHNE_26096.

BR,
Mario.

Carlo -- In the future, rather than resetting the whole machine there are two things you can do to get the console getty working again -- one hardware, one software.

Hardware -- If you are using a 700/92 terminal (or 700/96), you can power off the terminal, hold down the "d" key, and power the terminal back on while still holding the "d" key. Count to about 5 and let go of the "d" key. You should get a message on the screen that says "default configs used, press return to clear", hit return and the hardware of the terminal will have been reset.

Software -- Get a network connection to the box and do:

ps -ef | grep console

There is probably a getty process running. Type: kill

The to use is the first number on the line returned by the ps -ef
