Monitoring of a remote router is reporting rtt of 1000 ms (sometimes up to 3000) and packet loss of 30-60%. If the rtt was higher I'd be expecting some sort of malicious activity going on but at 1000ms I think that's unlikely, but obviously I can't connect to find out so won't be able to investigate until tomorrow morning. Are there any tricks for connecting to a troublesome connection like that? Any way to fiddle with TCP options to send 2 copies of each packet (to overcome packet loss) and increase timeouts etc? It won't do me much good tonight but could be useful in the future. All I can really think of is to reduce MSS to give me smaller packets which might be less likely to be dropped (assuming the problem is line noise and not congestion). Thanks James

I don't know. This scenario makes a good case for a dial-up modem connected to a router's serial port.
Then I could use here for my net access with a 56K modem, and provide around several PC's. At the moment, Gnome NetManager has advantages when I take the Thinkpad elsewhere, or the desktop PC to get a fast connection in a not so close neighbours house, but I will need to learn how to do the equivalent manually, along with sorting out the right bits to disable or uninstall to get rid of NetManager.
