i've recently installed fedora core 2 on my system, and normally connect to the internet via an external dialup modem. Linux identifies it as: "Ambient 3200 56k Modem"
i'm able to connect to my ISP via kppp, however once connected, i can't view any webpages, make any ssh connections, use any messaging clients...pretty much utilise any part of the connection.
I'm not sure whether this is a driver issue (as it was able to connect) or an issue with security settings. Either way, i'm not sure how to go about fixing this. Previously I had Redhat 9 installed, and i had none of these problems whatsoever...
is anyone able to shed some light on my situation, or point me in the right direction?
1. modem connection
in kppp you can querry the modem (if I remember right there is a modem tab that can be accessed as part of setting-up an ISP) it is worth checking that the PC is talking to the modem properly.
2. also if you check the view log box on the kppp dialog (pretty sure its called that -I'm at work on my lunch break in front of a win 2K machine) you an see if the logon is successful
3. I also used minicom when I had connection issues but kppp log gnerally seems to be enough
when I ran Mandrake 9.2 it would display the ISP name on the toolbar but the ppp deamon had "died unexpectedly" (in my case this was random and could be 1-5 minutes after logon) but this was on a pop-up window that was often hidden . When this happens no internet functions will work , in my case this was due to too much load on the line.
my modem is definately detected, as i had originally queryed it in kppp, coming up with expected results.
another thing is that upon running cat /etc/sysconfig/hwconf my modem is not listed there
from pinging striaight ip addresses, i do get results, but not from piniging through the URL. i can also access these ip addresses via mozilla, e.g. the LQ ip, google's ip and yahoo, but no images are loaded.
that sequence of commands shows this.
Code:
#service iptables stop
$ ping -c 4 linuxquestions.org
ping: unknown host linuxquestions.org
$ ping -c 4 64.179.4.149

$ cat /etc/resolv.conf
not sure if that resolv.conf file should contain anything...but it's blank at the moment
its all a bit confusing, as the modem *does* appear to work, but only for some things..
Had the exact same problem,installed FC2 went to kppp and configured dial-up to my ISP hit connect button on the gui heard the connection being made and thought I was about to browse the net.NOT! Tried Mozilla and Konquerer but no luck.queried the modem and everything was fine,Googled,posted to and read the Linux forums,read magazines,books,etc.This had been going on for a few days and I was becoming frustrated and then decided to browse this forum when I came upon a post with the same problem that contained some suggestions on possibly resolving the problem.After reading 'darthtux's' reply:
Quote:
/etc/resolv.conf only has to contain one line containing the IP address of your ISP's primary dns nameserver like this"
code:
nameserver xxx.xxx.xxx.xxx
just replace the x's with the ip address. Get the secondary and add it in its own line. Just in case their primary is having trouble.
It dawned on me to recheck my kppp configuration. I went to my ISP website and got the primary and secondary DNS address,used another computer to get the info but you can call your ISP's tech support and get it also.Opened kppp and hit the config button on the gui selected Accounts highlited account name then hit Edit>DNS>Manual,type in DNS IP address>OK then you should be ready to "surf the web".Well anyway I hope that will do it.I am currently posting this reply on the machine that I made the the simple edit of adding the DNS IP address to get my browser(Konquerer) online.
Thanks for the enlightenment and inspiration to go on.
