Re: [newbie] host name look up failure
Thanx alot for the reply Derek.To answer you 1 by 1 here... 1)Yep..127.0.0.1 localhost is there alright... 1 for 1 eh :) 2) DNS is indeed enabled,and the ip of the proxy is there..so good so far :-) 3) The default gateway is also the ip of the proxy. Now something that's bothering me is this,I was under the (false) impression that if I used a host file,I didn't need DNS. anyway..I do have DNS enabled (required for normal operation ?) in linux.conf (under names server spec) I'm still geting this host name lookup failure in the place I described below? Anyway's it's 3:30 am sun. morning and I'm still trying..lol Hava great Sun. all :-) Lee Do you have an entry in your /etc/hosts file that says 127.0.0.1 localhost Do you have your DNS enabled and the host names of your DNS servers in it? Have you declared a default gateway? The default gartway will be the IP address of the machine between you and the Internet. You can use netconf to set up all that stuff.

Re: [newbie] host name look up failure
I forgot to ask the other obvious question. Have you entered the proxy port nunber into your browsers proxy settings? The default port number for Squid is 3128 However you should still be able to surf without Squid being properly configured so long as you have enabled Network Address Translation (NAT or IP Masquerading) in the Gateway Computer. Can you surf if you do not declare the proxy in your browser? You can test if IP Masquerading (NAT) is working if you can ping the Ethernet adapter on the Internet side if the gateway computer. If you can ping that, then try pinging the DNS servers. If that works then try pinging a network server by name like :- ping www.yahoo.com It might be worthwhile stopping the Firewall while you debug the system. Firewalls are notorious for stopping services and get in the way of faultfinding. You can stop the firewall with this command /etc/rc.d/init.d/bastille-firewall stop As for your question about Host Tables and DNS. Your computer has to try to resolve network host names into IP addresses since IP packets use only IP address and never host names. It will always start by looking at the host table. If there is a match there it will use that IP address. If there is no entry in the host table for a given name, then it will use DNS to look up a name. This is why leaving out the 'localhost' entry is bad. If the localhost entry is missing, then everytime the computer has to attach to a local socket the computer will go and ask the DNS server where 'localhost' is, and of course will not get an answer.

Re: [newbie] host name look up failure
Thanx again,very much derek for taking the time to reply. The port # has been entered. 3128..I've also tried using port 80 port 8080 too..lol. Anyways I'm back to 3128 as we speak :-). It definately won't surf when configged as a direct connection. The firewall has been shut down, I was using InteractiveBastille,which along with iptables chains have been shut down,taking no chances for the moment..lol I'm not sure I understand what you mean by pinging the nic on the 'net side So now in the meantime I got the bright idea to just try a fresh install (idiot) cause now I'm back to the problem of getting that modem is busy message again I fixed this once before and I can't remember how I did it !! So I'll start over again.The good part is no Bastille has been configged at all. Gotta get some air now tho..lol. Hava great Sunday friends :-) Lee I forgot to ask the other obvious question.

Re: [newbie] host name look up failure
I'm not sure I understand what you mean by pinging the nic on the 'net side Just that your gateway computer has two network interfaces. One facing the internal network, the other facing the outside world. You ought to be able to ping both interfaces from within your internal network. derek Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com
