Modem trouble

I agree with mdw that it looks like a hardware configuration problem since minicom gets no response at all from the modem. I would try minicom against /dev/ttyS0 throught /dev/ttyS7 and see if any of them will respond to minicom.

Thank you, that did it. I tried minicom on all the port until I found one that worked and then I relinked /dev/modem to that. It turned out it was /dev/ttyS4 that I needed (which doesn't make any sense), but at least it works.

Ok, so ppp-go and kppp will now successfully connect me to my ISP. However, when I try to go into Mozilla or gaim, nothing will load or work. It is as if I am connected but I can't send or receive any data other than the initial data used to establish the connection. I thought the IP address of the ISP's nameserver part of pppsetup might be messed up (since I left it blank since the DNS should be set automatically, in Windows I never had to set up a separate IP for that and I think I got online with Linux before without finding a special IP). However, I changed this to the name of my ISP and then when I tried to connect I immediately got a 404 error, whereas before it sat there trying to find the page for a while. What could be causing this?

I'm almost there

" I can't send or receive any data other than the initial data used to establish the connection. "

This may be a permissions problem where root can use /dev/ttyS4 but user cannot. Try setting the /dev/ttyS4 permissions to 777 and see what happens.

I set the permissions to 777 on both /dev/ttyS4 and /dev/modem and there is no difference. I found the URL for the auto-proxy config .pac file in my windows configuration, and I put that into Mozilla, but still no response from either Mozilla or gaim when logged in as either root or my user.

I think you need ISP domain name AND namserver IP address in pppsetup and kppp. May want to run the config utilities again or edit /etc/resolv.conf file so your browser knows where to look for nameserver.

I was thinking this might be the problem. How do I go about determining my ISP's nameserver IP. Is there a place where that is entered on a Windows computer... I don't remember having to determine the actual IP. It was my understand that the auto-config .pac file set this up, but I could be wrong. Do I need to call my ISP and determine the actual IP?

Ok, I went hunting around in Internet Explorer and found the nameserver part, and it is set to "Server Assigned Nameserver Address." I was hoping that if I left that entry blank in pppsetup it would do this, but I guess not. How do I let the server assign the address?

When I singed up with my ISP they gave me the addresses for their nameserver. I guess you should contact your ISP for this info. I checked my winbox and it is setup like yours, with server assigned nameserver IP. I don't know how to do this in linux ppp but it would be nice to learn. Like I said earlier, I'm new at this too.

Well, I will try calling my ISP later but I really would like to see if it is possible to set it to "server assigned." Does anyone know of a way to do this (or does anyone know for a fact that you _can't_ do this)? It is always nice to let the server do that work, for example, if the nameserver IP changed I wouldn't have to go through this whole process again.
