Hi Guys, I have a setup where i have a user named root4 whose uid and gid are set to 0 so that it behaves as root user. The root user has ssh keys configured to access other servers . In the existing setup all other servers with similar setup shows whoami as root ,though i login with the username root4. In one of the servers all of a sudden it shows as root4 instead of root. The only change i did a day ago was installed fluxbox and k3b for burning dvd-backups in the server itself. Since it shows whoami as root4. ssh checks /home/root4/.ssh for ssh keys instead of checking in /root/.ssh/ so i have to copy all the keys manually from default location to /home/root4/.ssh to get the ssh key based authentication working . This machine runs centos 4.5 Id still shows uid =0 (root4) gid=0(root) groups=0(root) but its supposed to show uid =0 (root) gid=0(root) groups=0(root) Earlier all files in /home/root4 are owned by user and group root.root now it shows root4. root. i checked the passwd file last modification date and it hasnt been changed for months. root4:x:0:0::/home/root4/:/bin/bash selinux is disabled $HOME=/home/root4 -- which is normal. I dont know why it behaves all of a sudden. does anyone have experienced similar problem ? Where should i look for to fix this issue ? Any help would be much appreciated. -- Regards, Mohan.
