ppp dials up ISP but I can not access internet

I hope this is the right place to post this question.

Could this be a frewall issue?

I have been usng Slackware 10 and KDE for a couple years now and all of a sudden I can not access the internet.
With browsers I get "Server not found"
No browsing, e-mail, ping, whois...

root@thunderbolt:/# ppp-on
root@thunderbolt:/# Serial connection established.
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS0
PAP authentication succeeded
local IP address
remote IP address

root@thunderbolt:/# whois
getaddrinfo: Temporary failure in name resolution
root@thunderbolt:/# ping
ping: unknown host

Any ideas would be great.

This may be a problem with /etc/resolv.conf not being set up properly. You can test whether resolv.conf is the problem by entering the two following addresses into your web browser:

If you get through on the number address but not on the name address then you do not have /etc/resolve.conf set up properly.

Thumbs up Seems the ISP changed nameserver ip address

Thanks for the help.
I contacted the isp and entered the new nameserver address in my resolv.conf file.
I stll have no idea how my firewall works but at least the problem is solved.

I like slack!
