Q. Machine booting up, but GNOME Graphical windows not coming, not even the login screen (Redhat 8.0)

A. Check whether your /tmp directory is full. Clear it.


Q. How to install/reinstall Apache with modules A, B C?

A.
  1. Download Apache from apache.org
  2. untar tar.gz
  3. ./configure --with-modules="A B C" PREFIX=<path_to_installation_direcotry> (Or consult INSTALL file that came with the download)
  4. make
  5. make install



Q. Mounting NFS drive failed: Permission denied

A. This happened after I changed papangul's IP, but I think that has nothing to do except triggering the problem. To solve, I had to add three lines with client name papangul (there were lines with IP 192.168.0.* previously which used to work) in server palowan's /etc/exports file. Then restart nfs service with service nfs restart.

The idea I finally got from the Linux-NFS-HOWTO, more specifically 7.3.iii) where it says: One trick is login to the server from the client via ssh or telnet; if you then type who, one of the listings should be your login session and the name of your client machine as the server sees it. Try using this machine name in your /etc/exports entry.

NOTE: There may be quite a few different reasons for this failure. So check the HOWTO or Redhat Configuration Guide or Google.
