[newbie] Internet Problems

[George Petri]

Hi!   I recently set up a network and fooled around with my networking config files and now DNS lookups don't appear to work :(, which explains why I have been recently using Outlook Express to send emails...   Basically, I can connect to the Internet with no problems but once I'm online, I can't do a thing.   If I type ping www.<any website>.com, this message pops up on my screen:  YPBINDPROC_DOMAIN: Domain not bound  And ping just sits there waiting forever.   If I run Konqueror or Netscape and type in www.<any website>.com, they also just sit there forever and never load.   Before, I changed my config files, Internet in Mandrake (I'm using 7.2) worked fine.  I have always used kppp to connect to the Internet.  I have always been using the LT WinModem 5.78D driver.   What is wrong?  I want to use the Internet in Linux, not Windows!   Perhaps, my config files have something to do with this, so here they are :)   ---------------------------------------------------------------------- /etc/hosts:  (btw, I have named my computer "tux350" and the    other one on the network, "cups166", in my pretend domain "reisersun") ---------------------------------------------------------------------- 127.0.0.1               localhost.localdomain localhost 192.168.1.1             tux350.reisersun tux350 192.168.1.2             cups166.reisersun cups166   ------------------------------------------------- /etc/HOSTNAME (note: this file did not exist before I made it!): ------------------------------------------------- tux350   ---------- /etc/host.conf: ---------- order hosts, nis, bind multi on   ---------------------------------------------------------- /etc/resolv.conf   (note: I use an isp called Bigpond, which has everything    - ip addresses, that is - starting with 139) ---------------------------------------------------------- # search reisersun # search localdomain search localdomain   # nameserver 192.168.1.1 nameserver 139.134.5.51 nameserver 139.134.2.190   # ppp temp entry nameserver 139.134.5.51 # ppp temp entry nameserver 139.134.2.190 # ppp temp entry nameserver 139.134.5.51 # ppp temp entry nameserver 139.134.2.190 # ppp temp entry   ------------ END CONFIG FILES -------------   I can't remember the numerous other config files that I changed so please tell me if you need any others to help diagnose my problem.   Before I changed anything, my computer used to be called the default "localhost.localdomain".   Please help me fix my config files so that I can use my Internet connection again in Linux!   Thanks, George
