Unix Login problem URGENT
|
|
|
| Dear Experts,
We have the Oracle Database running on DG/UX AVIION 3600 hardware ( SERVER)
Now while working, I have given the command to (tar) /etc/passwd to Digital
Audio Tape --- but it has some hardware problem and the console got hanged.
Later after many Control-C, I could get (#) prompt.
At that # prompt I gave (exit), which took me to Console Login.
Now it is not allowing me to login by root or sys or by any other login. I
believe the /etc/passwd file is corrupted.
Please help me to get the (#) prompt, because I have the copy of /etc/passwd
in some other directory. I am also unable to login from remote terminal by
TELNET or FTP. The System is ON and ORACLE is UP
UREGENT PLEASE HELP
Thanks in advance
-Tanveer

Can you reboot the system from a different device? Then you could mount
your usual disks separately, and replace /etc/passwd.

| No possible: NO Telnet or even FTP is being allowed by the system.
Plz Help

Please don't top post.

I think Jeff meant something like: Can you boot this machine ie. with
Knoppix?
If so, you could mount your disks from within Knoppix and replace/repair
your 'passwd'.

If Knoppix can boot the box and read the FS?
The common solution is to boot to single user after a forced
shutdown, from some console or switch the system off by hand.
Many *nix don't require a password in single user mode.
Mount the needed FS and empty the root password in passwd/shadow
or wherever it is on this system. The manuals should know more.
