You need to start a new thread. This thread is about something totally different. The only thing is you both need to explain your problems better. ie more detail. I can't understand what either problem is.

hi gogalthorp,

actually i don't know how to explain the problem but i just can tell u the situation. A server in my opis got a problem which i can't logon. i put the username and password but also can't.it just displayed 'error in service module'. I didn't knew what the problem but i can saw a lot of operation 'failed' after that server restarted.However, i can connect to that server using my computer's terminal console using ssh root@<that server's ip> and it's password. i think i can use this console to solve that problem but how?..

[gogalthorp]

Do you mean you can't log on remotely or can't log on at the server??

It sounds like you have a serious corruption problem. I'd do a low level disk check then reinstall or update the OS.

Dear,
I have no enuogh time to describe this - but study about these files

/etc/passwd //username and password configuration
/etc/shadow //additional password security
/etc/group //Group configuratons
/etc/gshadow //Group Security

and home directory of perticuler user

every user configuratoin are stored in those files. you can log on to your linux server using ssh cliant (use putty ) and edit those files - delete existing root accout and create it again

also try useradd, and userdel commands - which can add and delete users in linux computer

tq montero and gogalthorp..

gogalthorp: i don't want to repair or reinstall because i'm really2 new in Linux

montero: i like to try your steps but i don't know how to insert or edit some file using ssh..can you or someone else describe it to me..sorry..

[akuinblues]

gogalthorp,

sorry because not answer your question above. i can't log at the server and also can't log remotely(KNX client) but i can log on to my server using ssh root@..it's so urgent now...i know that i can change the files in the server and edit them like montera told above but i don't know what to do when i'm in ssh..

tq..

first you should download putty (its my favorite ssh cliant)
http://the.earth.li/~sgtatham/putty/.../x86/putty.exe
Double click on it type root@<ip addrss of server> then password. it will login to your linux server then first create another user who belongs root gruop

[montero@montero~]#useradd -g root -d /home/montero montero1

[montero@montero~]#passwd montero1

give passwords for new user
it will ask

new UNIX password: <type your password>

conform it

now you you can try to logon your server using new username and password
here -d represents home path and -g for group


May be error on your x server
try kde insted of gnome (at the login screen "change session")
montero1 is the username
