A simple bash script to do some basic checks on the system, and report any problems found. The basic concept is that this script should be run as a first step when debugging any issue. Nothing in the script requires root privileges to run.
Please note that there are some situations where this script may cause a system with problems to hang, for example if there are unavailable mounted volumes.
You can run on any system with internet access directly, even if the disks are remounted read-only:
curl https://raw.github.com/BashtonLtd/whatswrong/master/whatswrong | bash
Alternatively, as long as you have SSH access to the remote system you can download via your local machine, and then send and execute over SSH as follows:
curl https://raw.github.com/BashtonLtd/whatswrong/master/whatswrong | ssh $remote_server bash
You could add a commandline shortcut to this by appending the following
to your .bashrc:
ww() { curl https://raw.github.com/BashtonLtd/whatswrong/master/whatswrong | ssh $1 bash; }
You can then run the script on any machine you have SSH access to with
ww $remote_server
You may need to add -k to curl, however, beware that this increases the potential for a man-in-the-middle attack. As the script is not run as root, this is less serious than it might otherwise be, but should still be considered.
