Hi everybody,
We have configured a proxy server by using RH7.1 and SQUID. Our intention
is to use the box to have internet connectivity to the LAN users. The users
will be doing web browsing and will be using direct FTP (not from browser)
also.
We have done the following things:
1> Configured the SQUID so that it allows access to port nos. 80 and 81 (81
is needed for a chat server)
The configurations are given below:
http_port 80 81
acl safe_ports 80 81 21 443 563 70 210 1025-65535
http_access allow localhost
acl ourlan src 10.16.0.0/255.255.0.0
http_access allow localhost
http_access deny all
2> changed the rc.fw in rc.d to read as follows:
/sbin/modprobe ipchains
/sbin/ipchains -A forward -s 10.16.0.0/16 -j MASQ
/sbin/ipchains -L -n
Now the users are getting internet properly. But we cannot do ftp from any
client machine. Though the ftp is working fine from the proxy server
itself. When one tries to connects to a ftp server the user is able to
login. But commands like dir,put,get are returning error
500 Invalid port command
Can any body help please ?
