The main servers are Redhat. The client laptops are windows and OS X.

Agreed. Is there a preferred way of doing that? Or just start an independent thread and close this one?

Yes, but I guess the question now is how to get Windows and OS-X clients to automatically use a proxy when their main route to a server fails.

AFAIK Windows clients are either configured to use a proxy (all the time) or they aren't.

AFAIK you can't have, say, IE connecting direct and Firefox using a proxy. I believe that they both look at the network configuration of the machine. Otherwise you could have told your users to use the other browser when the problem occurs but I don't think that will work.

Hmmmmm.........if we ask moderators to move this thread do we move it to Windows, OS-X, or both. Also, Networking might be a good shot as networking experts may know a solution.

First point -- absolutely.

Second point -- okay -- gets more complicated when I'd hoped for a simple fix ( :-) )

Third point -- no, if one path fails, I'd have ALL users go to the proxy, and hopefully have the proxy automatically find a successful route.

Fourth point -- I'd like to keep this as general as possible, since I'm the only one using OS X and all other users are on Windows (well, most). So yes, networking would be best. OS X is essentially Linux, so I have access to any Linux solutions, but the Windows machines may not.

And finally -- is there an "official" way of requesting this sort of thing of the moderators?

Yes, there's a forum here called Post Here to Contact Moderators. I also often put "NOTE TO MODERATOR" in capitals in a post to request such a thing because the moderators of each specific forum usually read through the threads and will come across it.

Great -- first, our topology is that we have a cable modem from Comast that goes to our business router (also from Comcast) to our machines. Our owned IPs that we have trouble with are public IPs from Comcast, and can always be accessed from everywhere else BUT our local network.

NOTE TO MODERATOR:

PLEASE MOVE THIS THREAD TO IP NETWORKING as it is no longer appropriate for the "Emergency" forum.

Thanks

OK, I'm here and willing to help.

I have read the thread now and - without even knowing the topology of the network - i have absolutely no idea what could be done. "Proxies" are usually protocol-specific (like "http-proxy", etc.). Basically a proxy is a multihomed host claiming to be the addressee of an IP packet not really addressed to it. Maybe a picture helps:

Code:
host_intern <-------> proxy <---------> host_extern

When host_intern tries to contact host_extern the proxy instead answers, claiming to be host_extern. The proxy then contacts host_extern claiming to be host_intern, relays the request, takes the answer host_extern gives and then sends this to host_intern. Host_intern gets some answer to its request but the traffic is (silently) routed through proxy.

There are different kinds of proxies (for various protocols), one of the last developments are so-called "transient SSL-proxies", which do the proxying for SSL-connections. This way a company can effectively prevent that someone uses encrypted tunnels through their firewall to send/receive data without supervision.

Does this help? I know, there are no recipes for making it work again offered, but sometimes gaining understanding what goes on helps. Further, without more insight into the network topology and the intrinsics of the site it is nigh impossible to offer more than very general advice and/or explanations.

If you want the thread put somewhere else just say so - as long as the request is reasonable i will so without hesitation.

I hope this helps.

Moderator's Comments:
Mod Comment /PS: just saw your latest posting after finishing to write my own one. Will transfer the thread to IP networking.

/PPS: it is perfectly OK to notify a moderator via PM to take some moderative action. We are just reluctant (for obvious reasons) to offer technical advice via that channel.
