Cannot login at console

Penny Stoever — Mon, 17 Dec 2007 15:34:16 GMT

Whenever I try to login using "co" or console, I get a run of messages saying that DT login is broken but when I type in root at the console prompt it just gives me another prompt and never asks for password.

hi penny ;
please look at your /etc/hosts file for entries

localhost and hostname of your machine.

Wish I could. I have no way to log in at all.

Not sure "where" you are.

Do you try to get the console from the MP?
What terminal emulator are you using?
Wrong settings for an emulator could lead to strange behaviour.

Can you login remotely? How about users other than root?

Here's what happened. I got onto the server from a laptop using hyperterminal - i think it was using vt100 settings but I'm not sure. I changed the IP address by changing the netconf in the /etc/rc.config.d to reflect the changes and the hosts file, too. When I rebooted, I found that I could reach the server via ssh but I didn't have my old password to log on as myself and root is barred from ssh. So I went back and tried to log in using hyperterminal and this time it said that X would not work and to hit CR to get a login prompt. I did this and it gave me a generic prompt at which i typed "root". It rejected this giving me the exact same prompt again. I'm stuck! Any help would be appreciated.

hi penny ;

please change hostname or ip address by set_parms command.
eg
set_parms hostname
set_parms ip_address

use again that command " set_parms hostname " and fallow .

First of all try to use putty - hyperterm with a wrong setting could give a double CR instead of only 1.

I tried using putty - same problem. It says to see /etc/issue but since I can't log in.... Don't I have to be logged in to use set_parms?

Do you have access to the GSP/MP/iLO?

Re: Cannot login at console

Penny Stoever — Mon, 17 Dec 2007 16:15:36 GMT

Yes, I've been in there. Can I log in from there other than using "co"?

Re: Cannot login at console

"co" command connects you from the MP to the console - no other way from there.

The serial connection to the console is not really network related - so the problem may be different.

Can you connect to the SMH?

I tried that but no. I tried using http://123.123.123.123:2301, is that correct? This is an old server (A500) running 11.00 and uses GSP (vs. MP). Is everything the same on those?

Re: Cannot login at console

Nothing like smh on the unsupported 11.00 version.

From the GSP you should review the console log and search for errors while booting (CL command).

If you have no other user to logon and su - you may consider to bring the system down and start in single user mode.

Wow, I wasn't aware of SMH before - it's pretty cool. Thanks.

My server now indicates a hardware error, but I do have another server with the same problem (can't log in at console). Unfortunately, that server doesn't have SMH either. I am working with HP and will post a solution. Thanks to everyone for suggestions. If you have other ideas, they are most welcome.

It turned out that CA's Access Control was somehow barring access to the console by anyone. Thanks for your input
