Managed to make myself look like a fucking moron again today...

Can't mount NFS share, get "permission denied". Huh, that's weird... It's correctly exported.

Well it's correctly exported and rpcinfo -p $HOST times out... Must be firewall rule.

Firewall rule is changed but still no joy "permission denied"... Fuck sake networks, can't you do anything right first time?!!!

Firewall rule is correct I am reliably informed... Go about proving that it's not fucking correct and provide "evidence" to show this, I was a little bit more blunt than was strictly required.

Networks say they will take another look.

I turn NFS logging to verbose for my own interest and notice the line "path/to/directory is not a valid directory".

I, as a moron, had missed a "/" at the start of the path. That's why I still couldn't mount after the firewall change.

Go over and apologise in person and explain how I'm a total idiot.
