squid problem !!

[hisham]

I have SuSE 9.0 box "ip : 192.168.0.2", i am trying to setup squid in this box. After the installation and configuration, i could connect to this server from another client "ip : 192.168.0.100" using port 3128, but only i had access to the pages in ServerRoot "/srv/www" , but i culdent access the internet using squid niether in the server or in the client. I checked /var/log/squid/access.log and i found:

1089645186.615 531 192.168.0.100 TCP_MISS/200 46767 GET

http://192.168.0.2/

1089645220.271 144915 192.168.0.100 TCP_MISS/504 1419 GET

Is there any missed lines in squid.conf ??
Thanks in advance for any help ...

Good question. What *is* in the squid.conf, anyway? Also, Can the proxy server properly resolve DNS names?

 

[hisham]

In squid.conf the only 2 lines i added was:

acl mynet src 192.168.0.0/255.255.255.0
http_access allow mynet

I configured the server as master DNS server " also keeping the Cashing_only Name server" and it runs fine over the LAN, but i don't know how to make the proxy resolve the DNS names, is it in the squid.conf file?

 

[lgarner]

Can the server resolve names? If it's the master nameserver, do you have forwarders enabled? I assume so, or it wouldn't be a good nameserver for your workstations.

How about its resolv.conf? That's where squid gets its DNS configuration unless otherwise specified in squid.conf. For testing you could modify the dns_nameservers tag and see what happens.

Finally, can you access external websites via IP address? That'll really determine if the problem is DNS-related.

Yes, the server can resolve names, and convert names to IP addresses.
I connect to the Internet using ISDN, after the connection the /etc/resolv.conf looks like:
-----------------------------------
### BEGIN INFO
#
# Modified_by: ipppd
# Backup: /etc/resolv.conf.saved.by.ipppd.ippp0
# Process: ipppd
# Process_id: 7724
# Script: /etc/ppp/ip-up
# Saveto:
# Info: This is a temporary resolv.conf created by service ipppd.
# The previous file has been saved and will be restored later.
#
# If you don't like your resolv.conf to be changed, you
# can set MODIFY_{RESOLV,NAMED}_CONF_DYNAMICALLY=no. This
# variables are placed in /etc/sysconfig/network/config.
#
# You can also configure service ipppd not to modify it.
#
# If you do not like the ipppd to change your nameserver
# settings remove the option MODIFYDNS for this provider
#
### END INFO
search mydomain.com
nameserver "IP of my isp"
nameserver "another IP of my isp"
-----------------------------------------

if disconnected the file looks:
-----------------------------------------
nameserver 192.168.0.2
search mydomain.com
-----------------------------------------

when I tried to access external sites vi IP address, i get the following message:

ERROR


The requested URL could not be retrieved


While trying to retrieve the URL:

http://216.109.127.28/

The following error was encountered:

The system returned:

Try running "route -n" to see what the routing table looks like. This seems to indicate that no IP traffic (including DNS) is getting out. I'm suspecting a connection problem.

Try pinging internet hosts, by IP then by name, from the server console.

there is no connection problem, because i can connect to the internet when i stop squid
