Dear friends
Our Red Hat 8 server is not accepting IMAP connection telnet to port 143 says : "* BYE Service not available edp0.iacc.org IMAP4rev1 2001.315rh at Fri, 3 Jan 2003 18:13:27 +0530 (IST)"
I tried by flushing all the iptables rules also.
And our local machines on the LAN are not able to connect to the FTP server outside the network, But it can browse the internet using squid proxy.
please help me how to solve these problem. I googled a lot, didn't help it.
Regards Benoy George

It *is* accepting TCP/IP connections. iptables won't help here. You need to check the IMAP/xinetd config files for that.
And our local machines on the LAN are not able to connect to the FTP server outside the network, But it can browse the internet using squid proxy.
Set up routes for 0.0.0.0 properly. Also check whether the default gateway allows you to connect outside ( If it's a Linux box, check whether ip forwarding/ masquerading is enabled etc. etc. )

Check the number of established connecvtions with netstat.

Try NAT and passive ftp.

Hello Benoy, good-evening.
And our local machines on the LAN are not able to connect to the FTP server outside the network, But it can browse the internet using squid proxy.

you will need to do the following.....enable NAT in the Forward chain using either Iptables/Ipchains.
Once this is done all your problems should be solved. Squid only proxies HTTP traffic and FTP isn't configured by default. Its better if you make use of kernel level firewalling/NAT as mentioned above.
If you have any issues give the NET-3-4 howto's a shot. There are many a howto's lying aroung for the same.
Bye for now and have a great day.

Thankyou all for the replies IMAP is working now. but the masquerading is still having the problem, routing table is showing the default route to ppp0.
while command mode ftping from the gateway server to the outside network its saying 'no route to host' after the successfull login. I can run the cd command. but no ls,get,mget
ftp> get index.php local: index.php remote: index.php 227 Entering Passive Mode (203,197,38,3,139,13) ftp: connect: No route to host ftp>
Any suggestion please. regards Benoy
