I am running RH6.0 Linux basically as workstation (I have 2 accounts set up - both me for different purposes) on a 486 DX2 66Mhz with 20096KB RAM, and a Creative Labs Modem Blaster 56K MODEM. I am using Kppp to connect to the network at work and to try to connect to the internet through my ISP by dial-up.
When I dial into work, I have no problem logging in and running any application I want (it's MUCh faster than eXceed and Windows :-) ). But when I dial up my ISP, I continually have problems logging in, and if I can log in, I may be able to get on the internet for a while, but slowly (over about 15 minutes) things get worse, and finally I cannot even ping my ISP's name server or even the remote IP address the ppp session says I am connected through.
I have been on the phone with my ISP, and he only does Windows, so he isn't any help with Linux, but he just says it's the phone lines between him and me (some are very bad).
I am not sure what to do about that. But the thing that mystifies me even more, is that after I connect to my ISP, my hostname changes (say if I do an su root or open a new kvterm) to rack-xx.deltaforce.net at some point, and even after I disconnect from my ISP, it stays that way so that I cannot run any other X-apps - I have to shutdown and reboot the computer (there may be another way to do this, but that's part of why I am writing). When I dial up my work, this does not happen. I can work for hours online without any problems, and I can open new kvterms without the hostname changing, performance degrading or X-apps refusing to run because the cannot access the server.
I have copied a ppp account in Kppp of my dialup to work, then changed only the name, number dialed, and anything else that might be specific to my ISP, but that doesn't work either.
So, my first question is this - when I dial in to work or to my ISP, I am given an IP address dynamically. Is there a file or variable in my system that has that value stored in it while I am connected, and then is reset after I disconnect (or is suppose to reset)? If so, what file is it and where is it? I see that HOST=rack-xx.deltaforce.net when I do an ENV after I disconnect from my ISP, but I have not been able to figure out how to change that. No command I have tried changes it. Do I have something set wrong or setup incorrectly?
Second, when trying to dial up my ISP, while it says it is logging onto the network, I get disconnected, and the log file says the MODEM is being sent a hangup. Both my MODEM and PPP timeouts are set at 900 seconds. Why would this be happening. My ISP says it is noise on the line causing it.
Any help anyone can give me will be appreciated. I have been frustrated with this ever since I tried to connect to my ISP. I seem to be getting farther, but in other ways it seems to get worse. :-(
One other thing is that I can connect and do whatever I want through my ISP and work from my Windows 98 Laptop.
