I often mount a remote drive using sshfs. I would love to have this mount automatically. However, if I mount it in my .bashrc or startup scripts, the mount often fails because my wireless internet connection has not yet been made.

Does anybody know of an easy way to execute a bash scrip every time the connection is made, or to auto-mount an sshfs drive?

Add your script to /etc/network/if-up.d/. Name your script without a '.sh' extension.

Also after adding script run chmod +x /etc/network/if-up.d/yourscriptname to give necessary permission.

Make sure the network interface (e.g. wlan0 or eth0) that should trigger your script when turned on is mentioned in the file /etc/network/interfaces.

inside scripts in /etc/network/*.d/ you can use the variable $IFACE to know which interface is getting a connection so you can skip the procedure if it is the wired connection for example. – Carlos Campderrós Feb 20 '13 at 9:22
    
Is there a way to specify which specific network you want to do this for? when it's my home network I want to do the script but when I'ts a network out and about I might not want to... – Joshua Robison Apr 28 '13 at 9:21

this actually doesn't seem to work at all. I know my scripts work because I can run them using ./ in the terminal and they work but when I toggle off and on the connection, the scripts are not called at all. Is there anything that I have to do to reference them in someway? dropping a script in if-up.d seems to be lacking a step?!?! – Joshua Robison Apr 28 '13 at 10:30

Please add what exactly should go into interfaces when it is not there. Is it auto wlan0 and iface wlan0 inet dhcp or sth else? – Cookie Mar 25 '14 at 15:40

Ubuntu 12.04

  • Install Cuttlefish Install Cuttlefish : A simple tool, which realises reflexes on your computer by executing actions when specific events are triggered.

cuttlefish is completely broken and hasn't seen an update for sometime. I wish it could get more development because we need something like Android's Tasker app for Linux. Nobody wants to mess with etc/network/interfaces and if-up folders and scripts. Just give me something I can click or toggle on and off. – Joshua Robison Jan 19 '14 at 4:17

The best, simple and easy way would be to add an up command to what ever interface on which you want work on.

Interfaces can be found in the "/etc/network/" directory under the file name "interfaces"

iface elan0 inet manual
    up filename.sh

This will add the up command to elan0. Simillarly give this to what ever interface you want to work on. Remember to indent one tab space.

Make sure you give the execute permissions to the file.

sudo chmod 755 filename.sh

Fantastic! Works with tun0 VPN interfaces managed by network-manager. The key is the use of inet manual. – KrisWebDev Jun 18 at 14:36

I will answer this part of the OP question: "I would love to have this mount automatically"

My favorite tool for automounting network shares is autofs: https://help.ubuntu.com/community/Autofs

AutoFS is my tool of choice to mount my NAS - for all my laptops and workstations.

"autofs is a program for automatically mounting directories on an as-needed basis. Auto-mounts are mounted only as they are accessed, and are unmounted after a period of inactivity. Because of this, automounting NFS/Samba shares conserves bandwidth and offers better overall performance compared to static mounts via fstab."

Your answer while possible may be a bit late as the OP already accepted the other answer. Your help is of course appreciated, however you might be better served by focusing your efforts on the unanswered questions – Wayne_Yux Jun 24 at 7:51
