Hi mathfeel,
what exactly do you have in mind? what are you trying to accomplish? can you be more specific?

I would like to run smbmount if and only if a network connection is available...I would like to do that in say .bashrc
how do I disinguish between eth0 being up or not (better yet, if I can identify the WORKGROUP/DOMAIN I am in)

well you don't do that that way anyway, with a line in fstab it will quietly fail if the network if not available.

if you did want it, there are loads of things you could try, such as checking the return status of a single ping to the samba host ( if [ `ping -c1 hostname`]; then ) or grepping the ifconfig output (if [ `/sbin/ifconfig | grep eth0 ]; then ) but there's no need.

the reason I want to do it in a script is that the folder I need to access has two level of access, RW is only available if I use certain username/passwd...so everytime I need to use it (and I use it frequenctly) I need to smbmount ... -o username=xxx
something like that....
I can't do this is fstab caz it doesn't give s*** about smbuser...whatever...
If you can suggest a better way, that'd be great!
