In many cases you don't want to allow default FTP port which is 21 and need to set FTP on different port OR you want both for FTP. Here I am specifying the steps to configure FTP on multiple ports and I am using custom port number 8226 here for FTP:
Pro-FTPD
in pro-ftpd, its quite simple and you just need to specify the different port in "/etc/pure-ftpd.conf" as given below:
---------------------
Port 8226
PassivePorts 30000 50000
---------------------
On my testing server I've added these lines above following line which works fine:
---------------------
# Umask 022 is a good standard umask to prevent new dirs and files
---------------------
Once you are done with the changes, restart the service:
---------------------
/etc/init.d/proftpd restart
---------------------
make sure it is working through following command:
---------------------
root@[~]# netstat -lpn | grep ftp
tcp 0 0 :::8226 :::* LISTEN 854817/proftpd: (ac
tcp 0 0 :::21 :::* LISTEN 854817/proftpd: (ac
---------------------
Now try connecting with both ports and it should work.
Pure-FTPD
Pure-FTPD configuration is bit lengthy but it is always recommended to use pure-ftp instead as Pure-FTPd is generally regarded as faster FTP than Pro FTPd. So here is the configuration for running pure-ftpd on multiple ports
1. Make a copy of default pure-ftpd.conf file
---------------------
cp -p /etc/pure-ftpd.conf /etc/pure-ftpd-8226.conf
---------------------
2. Edit the file /etc/pure-ftpd-8226.conf
---------------------
vi /etc/pure-ftpd-8226.conf
---------------------
3. Find and replace the lines
---------------------
# Bind 127.0.0.1,21
With
Bind 0.0.0.0,8226
---------------------
4. Now make a copy of the start-up script and run with the new config as a separate service:
---------------------
cp -p /etc/rc.d/init.d/pure-ftpd /etc/rc.d/init.d/pure-ftpd-8226
---------------------
5. Edit the /etc/rc.d/init.d/pure-ftpd-31 to load with the new config.
---------------------
vi /etc/rc.d/init.d/pure-ftpd-31
---------------------
6. Find and replace the lines
---------------------
$DAEMONIZE $fullpath /etc/pure-ftpd.conf -O clf:/var/log/xferlog $OPTIONS –daemonize
With
$DAEMONIZE $fullpath /etc/pure-ftpd-8226.conf -O clf:/var/log/xferlog $OPTIONS –daemonize
---------------------
7. Now start the new service.
---------------------
/etc/init.d/pure-ftpd-8226 start
---------------------
Done, now make sure that both ports are working
---------------------
root@vault [~]# netstat -lpn | grep ftp
tcp 0 0 0.0.0.0:6497 0.0.0.0:* LISTEN 7589/pure-ftpd (SER
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 23093/pure-ftpd (SER
---------------------
Note ::
# If you want to stop serving port 21 for FTP with pure-ftpd, simply stop the default service:
---------------------
/etc/init.d/pure-ftpd stop
---------------------
and restart another start-up script
---------------------
/etc/init.d/pure-ftpd-8226 restart
---------------------
That's it.
# The another important thing is that you need to allow passive port range in custom conf file (/etc/pure-ftpd-8226.conf), simply remove the comment (#) in front of below line:
---------------------
PassivePorts 30000 50000
---------------------
# Make sure that passive port range (30000:50000) and custom port (8226) is open in firewall if you have any
I hope this post will make your work easier :-)
