I just ran the WHM update to the latest RELEASE version for the Exim problem, and now I can't su to root in SSH. I used WHM's add to wheel group page on my username but it still can't su. It also doesn't list anyone in the wheel group except root in WHM, as if the page isn't working or something's wrong with the server. RH9.
-bash: /bin/su: Permission denied
-bash-2.05b$ ls -al su
-rwsr-x--- 1 root wheel 363105 May 4 23:20 su
Any advice? I am not a web host, chastising for not having a proper system admin not required
1) Create a new account in WHM, which in turn will create a new user.
2) Give the user wheel group privilages.
3) Login with that user, and it should allow you to su into root.
4) Delete all the accounts that do not allow you to su, and recreate them.
