Hi Experts,

Recently I had problem in my solaris system, to recover that I had restored the data from the backup (netbackup).

What I did:

I kept this problem system's harddisk in another solaris system. Formated the system, Created partitions as it has earlier. Mounted these partitions on the system with some names (Ex: "remoteroot" and "remotevar"). These are the two slices available in old system.
I had restored the data back onto these system from backup.

I could able to boot the system successfully. But when I try to login as a ordinary user(without root privleges), I got error msg " no shell. Some how I fixed it (The user was having tcsh shell, which was pointed to a different location).

The system is an NIS slave server.

I did try to do an NIS slave server setup on the system by using the command > ypinit -s servername.

I could able to login to the system with the account in nis environment but could not change to root using su.

Please help.

Thanks,
Rajesh

This is nis security issue.

check the permission on /usr/bin/su. is it 4750. change it to work with u.
check the group for /usr/bin/su /sbin/su.static, if u are not in that group, u can not run su.
