linksys WET54G - ping works, but nothing else

Tags:

hi there,

my problem is as follows (please note that i'm new to linux):

i run debian on my laptop, no gui installed. i tried to install kde with "apt-get install kde" but it told me "package not found". i soon noticed that i get the same error everytime i try to install a package. not naise.

first i thought i have no internet connection. but if i ping a website it works well.

and now here is what really scares me: my isp has a login system i do not know what it's called. it works like that with windows: i start firefox, type in an url, the login page appears in the browser window, i type in username and passwort, klick login, and it takes me to the desired url. i only have to login once, then i'm logged in until i shut down my laptop.

is it possible, that ping is working, but http / ftp requests to get packages don't work because of this login system used by my isp?

i would be thankfull for every tipp / hint except "ask your isp" ;-) because i would try to solve it on my own.

greetings tom

Do you have an install CD? If you have the full CD1 of the archives, you can do:

apt-cdrom add
then put in the CD and you will be able to install anything on that CD; I think it might even have KDE on it. If not, KDE will be on CD2.

If you have CD1 but no KDE, then you can try 'elinks' or 'lynx' - they may at least be able to help you get your network connection. Another trick to attempt to get that network connection (but it won't work if the machine at the other end automatically disconnects you when you pull out the ethernet cable): boot WinDos, log in, pull out ethernet connector and reboot, plug in ethernet connector as soon as WinDos has shut down and before Linux boots. The idea behind pulling the cable (or switching off the radio) is to prevent the 'logout' negotiations which will happen if you shut down WinDos (or any OS) properly.

'apt-get' also has facilities to use authenticating proxies; this will not work if your ISP doesn't allow connections unless you go to that specific page to log in.

Do 'man apt.conf' for more information on how to set up. There is also a very large example file which helps make the documentation a bit clearer. You might ask your ISP if they have an "authenticating proxy" or if you're forced to log on this way before doing anything else.

The 'other' way gets very technical and tricky - but if you love doing things the hard way:
1. man curl
2. After mastering curl (which is installed on ALL Debian systems), you can use it to retrieve that login page.
3. Look at the web source to see what fields are expected and how a reply is sent back.
4. Write your own little script to fetch the page, fill in the form(s), and submit - all without ever using an actual web browser (you probably need to install a utility like netcat).
