[SOLVED] Skip waiting for iSCSI targets during boot if not in known network

t0bias · 10-20-2013, 04:54 PM

Hello everybody,

on my Notebook I have installed Ubuntu 13.04 and configured two iSCSI-targets to mount during boot using fstab.
This works fine, as long as I am within a network-environment that is either my home-network or my companys network.
However, I am traveling quite a lot and every time I connect to a network where I need to get my VPN client running first (Hotels, Airports, etc.), the boot-process gets interrupted until the connection-timeout is being reached.
The mount-option _netdev is set, however this seems to be ignored by the bare presence of any WiFi network.

Is there a way to skip this process unless there is an actual connection with internet-access or a "known" network?

any idea is greatly appreciated!

You could remove the entries from fstab and write a script that checks for the home/company network presence, if so mount the iSCSI targets. The script can be run from rc.local (don't forget to background it).

Pseudo code:

Code:

if specific network is up
then
  mount .....
  mount .....
fi

Possible drawback: rc.local is run after all the other rc related stuff, iSCSI related mount points aren't available at that time.

Thanks.
I was hoping for a more "genuine" possibility - however, I'll probably just follow your advice
