permanent symbolic links?

[dbucky]

I was hoping for some help from someone with far more wisdom that myself, but any help would be appreciated. Here's the problem: I installed my modem driver which just so happens to be located at /dev/ttyS_PCTEL0. Kppp does not have this listed as an option in its modem configuration tab, so I have had to make a symbolic link from /dev/ttyS_PCTEL0 to /dev/modem in order for Kppp to find my modem and dial to the internet. This wouldn't be so bad, except that every time I restart the computer, I have to recreate this symbolic link. Does anyone know how I can make this link permanent?

Thank you for you time and help!!!

Re: permanent symbolic links?

I'm not 100% sure this'll work, but you can try this.

Create a script for the command:

sudo nano /etc/init.d/linkmodem.sh

Then in the empty text document, type

#!/bin/sh
sudo ln -s /dev/ttyS_PCTEL0 /dev/modem

and save (Control-X, Y, Enter) and make it executable:

sudo chmod +x /etc/init.d/linkmodem.sh

Wouldn't this route need the step of creating the proper symlinks in the /etc/rc.* directories for the runlevels you wish to enable it to actually run during boot? You can do this with 'update-rc.d' (see 'man update-rc.d' for details), or via the 'System Services' System Settings module.

Also, as init.d scripts are run as root, the 'sudo' is redundant on the ln command.

As a quicker solution (creating an init.d script for just one command seems a bit heavy ), you could add the ln command (ln -s /dev/ttyS_PCTEL0 /dev/modem) to /etc/rc.local.

(rc.local is an init script that is run on the later stages of the boot process, though it does nothin by default. It's a good place to run simple commands you want to run at the end of the boot process)

You can edit rc.local to add the command (ln -s /dev/ttyS_PCTEL0 /dev/modem) with:

kdesu kate /etc/rc.local

(Just make sure you place it below '#!/bin/sh' and above 'exit 0' on the file.)
