Hi
I just have a problem...
I'm behind an http proxy, it's 10.1.1.1 port 8080.. this is the scan of the proxy:

bash-2.05b$ nmap -P0 10.1.1.1
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on  (10.1.1.1):
(The 1585 ports scanned but not shown below are in state: filtered)
Port       State       Service
21/tcp     open        ftp                     
110/tcp    closed      pop-3                   
389/tcp    open        ldap                    
443/tcp    closed      https                   
445/tcp    closed      microsoft-ds            
1002/tcp   open        unknown                 
1720/tcp   open        H.323/Q.931             
5050/tcp   closed      mmcc                    
5190/tcp   closed      aol                     
6666/tcp   closed      irc-serv                
6667/tcp   closed      irc                     
6668/tcp   closed      irc                     
6699/tcp   closed      napster                 
6969/tcp   closed      acmsoda                 
7000/tcp   closed      afs3-fileserver         
8080/tcp   open        http-proxy              
Nmap run completed -- 1 IP address (1 host up) scanned in 422 seconds
bash-2.05b$ 

As you see the port 8080 is open .. and I put this "export HTTP_PROXY="10.1.1.1:8080" in .shrc so when I try to install something from ports it connects to the proxy and fetch the file. and that worked ..see this when i was installing epic4:
migz# make
>> epic4-1.0.1.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/epic4.
>> Attempting to fetch from ftp://ftp.epicsol.org/pub/epic/EPIC4-PRODUCTION/.
fetch: epic4-1.0.1.tar.bz2: size of remote file is not known
Receiving epic4-1.0.1.tar.bz2: 32768 bytes

You see it connects to the ftp server through proxy cause i found:
bash-2.05b$ sockstat -4
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS      
root     fetch      664    3 tcp4   192.168.10.102:3686   10.1.1.1:8080   <-- this

The problem is .. when I try to ftp manually i get 421 remove server has closed the connection.. cause it doesn't connect to the ftp server through proxy.. check this:     
$ ftp ftp://ftp.epicsol.org/pub/epic/EPIC4-PRODUCTION/
Connected to epicsol.org.
421 Service not available, remote server has closed connection.
ftp: Can't connect or login to host `ftp.epicsol.org'
$ 
in the same time i see:
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS      
migz     ftp        677    3 tcp4   192.168.10.102:3687   209.100.173.7:21 <-- it doesn't connect through the proxy server..
The question is how to make ftp and ssh connect through the proxy server 10.1.1.1:8080 ?
I hope you reply as soon as possible.
Thanks.
