hi all , i amtrying to configure samba on mandrake 9.1 which wil share files from winxppro machine.i amusing smbmount for the perpose and can mount windows directories on muy linux machine.but now i want to run all those smbmount commands for a user automatically when that perticuler user logs into the linux machine.
i belive someone can help me doing this.
thanks in advance

Put those command in: ~/.bash_profile, ~/.bash_login, or ~/.profile whatever is most apropriate for your distro and login shell.

thanks a lot.i am trying that and let u know what happens.but i am not getting one thing that is, all those commands generates a password: prompt where the user need to provide password.what will happen if i run it automatically.how i cn the script/commands be answared automatically.

I've never used samba, but maybe this works:

echo "password" | smbmount bla bla

Note that it is quite insecure storing password in a script. At least check that group/other have no reading and execute rights on the script!

If you are going to put the password right in the script like that, you could just as well do this for the mount portion:

This is pulled directly out of a script I have for mounting a samba directory, with the username and passwords substituted of course. ;)
