Hi Gyrene
Having the same problems here too, nothing automatic works, but we can do nearly everything manually.
We have YET to get rsync to find a remote hard drive, mounted or unmounted. But it works fine from command line on local drives. The irony of it, if we do a copy n paste to a mounted drive, it uses rsync to make the transfer without a hitch.
We've been doing most things manually ever since I installed Ubuntu. At first I just figured it was a learning curve I had to get past, but now I'm finding that I'm doing it right, it just don't work as expected. I can do the same things on CentOS (a RedHat clone) and it works just as expected without a hitch.
I've learned a lot, which lets me get around some of the many bugs, but personally I feel these problems should have been addressed years ago and no longer still be present.
You've probably already learned that if you go into the network controls it still shows that NO Ethernet Card exists! Don't know how I did it, but on one of my machines I could select to use eth0 or eth1 for the LAN and keep it separate from the eth0 used for the internet. I liked that, now I can't find it at all anymore and have one machine using eth1 that should be using eth0 since it don't even have an eth1 to work from, yet it works just fine, manually.
The ONLY thing about Ethernet that does work right is I have full internet connection on every computer through a hub to a router to the modem to the cable. It don't matter how I mix or match things, or move things around, it just WORKS, just as it's supposed to do.
My son stops to visit from time to time and just simply plugs his wireless receiver into the router and his lap top connects to the internet without him changing a darn thing.
But as far as file sharing with all the computers. I have to go through and use the GO/Location and type in the IP address of each computer and MOUNT the folders required at that desk, since they don't appear under Places/network as they should.
In other words, it's NOT that we can't get to them or that the LAN itself is down, it isn't. smbtree shows ALL the shares. But places/network can't find a single one, even though they are right in front of it's nose.
I have dumped network manager and installed Wicd and it has helped with a lot of little aggravations that were bugging the heck out of me.
But having to do everything MANUALLY takes a LOT of TIME!
We just had some more updates again today and true to course, the LAN dropped out until we rebooted each machine three times.
I think you said you were using NFS and Samba? I tried that and had some shared files showing up twice on the desktops and only one of them would keep the permissions correct. So I removed NFS and that problem went away.
Good Luck TTUL Gary
