FTP from server to server failure?

[jhyland87]

So the backups on my server have been down for a while, and I did some testing, it seems I cant FTP from my server to the backup server.

I can FTP to extreme-hq.com from my local computer just fine, but when I log into my server via SSH and try it, with the same host, username, and password, it says authentication failure.. any idea?

I checked the ports in my firewall, 22 is open for inbound and out.

root@prs [//]# ftp extreme-hq.com

Might it have something to do with

extreme-hq.com:root

Is that your username, toastedpenguin@extgreme-hq.com? It doesn't seem right and would usually be just toastedpenguin (without the @).

Also note that if you have firewall port 21open for FTP that you will be able to FTP into sites.. However, if you are using "Passive" mode it will try to transfer files (and list directories) on random, high-level ports such as 21234. When I use a firewall on servers I always switch FTP to "Active". This causes FTP to use port 21 for everything.

Jordan, toastedpenguin@extreme-hq.com is right, for sure...

ill enable active and see what happens

Thats from the log

When I SSH in the FTP to extreme-hq, I get this

Dear Justin,

While I can completely duplicate the issue. I can ftp from another server without a issue, while attempting to use your credentials from your server it gets an authentication error.

This isn't a firewall issue I've confirmed this by stopping iptables. (I thought this unlikely but I had to verify it myself.) Now I also tried using lftp to verify that there was nothing wrong on the server, this recieved authentication errors after connection.

My belief is that on the remote server has an rule to block access from your server specifically. I don't believe this is a firewall rule itself, more hosts.deny or the equivalent for pure-ftpd. Unfortunately this will be the extent we will be able to to troubleshoot this issue as the remote server isn't hosted by us.

Thank you for choosing The Planet.

Maybe the servers IP is blocked.. crap

I know that server you are trying to connect to didn't let me connect using an IP but did using a host-name. They do have funny rules there.

But I am using the host name..

whoa, maybe you meant the other way around, it let me connect via the IP!

[Jordan]

Really? I meant it the way you tried. So the IP works but not the hostname? Excellent.

[xxxkings]

then is there any confilict in the hostname???

Actually, he is now backing up to my server and I will be backing up to his server eventually. It will be a redundant backup scheme for us.
