[SOLVED]Cerberus FTP 5 to 6 & Server 2008R2 to 2012 issue

Post by Spade » Sat Apr 20, 2013 11:47 am

Hello, I'm experiencing something that leaves me in a bit of a conundrum... Last week I changed an old server for a new one and also updated from windows 2008R2 to 2012 Standard. With this change came the switch from Cerberus 5.x to 6. Before this change of hardware/software the FTP server was running beautifully but now it's dead. On the client side (doesn't matter which client i use) when i attempt to connect i get this http://i37.tinypic.com/213p0gh.jpg and after 1 minute, 5 minute, 30 minutes .. it's still just that, no error no nothing. On the server side (when i remotely connect to it to see the cerberus window for a real time error/log ) i get this: http://i35.tinypic.com/2ntfblh.jpg and ... nothing happens here either.

On the Firewall side, Cerberus is added and also on the client side the ftp clients are added too. Also, on the network equipment (router side, fiber optics translators) everything is the same, nothing has changed from the previous server.

Any ideas ... are welcomed.

Hello Spade,

Is the Windows Server 2012 running on the Public network profile? I've seen this happen on Windows Server 2012 machines before. A network change can sometimes switch the network profile into Public mode, and no connections will be allowed in.

Double-check the network profile, and see if the Cerberus firewall rules allow connections in using the current network profile.

It's definitely a problem external to Cerberus. The connections just don't appear to be allowed into the server.

Hmmm just checked now and you're right. It was set on Public Profile and didn't have that setting in the firewall option for Cerberus. I modified it but it still doesn't work. Turned off the firewall too, just to be on the safe side, and still .. no connection, no log, no nothing.

LE: I tried a different FTP Server, and it worked without issues.
LE2: Did some fiddling around and I finally got an error message that reads

2013/04/23 21:16:50 Failure in reactor event loop: The parameter is incorrect.
2013/04/23 21:16:50 Unexpected error: Exiting Listener Thread


... but i don't know if it's of value to the issue.

Hello Spade,
2013/04/23 21:16:50 Failure in reactor event loop: The parameter is incorrect.
2013/04/23 21:16:50 Unexpected error: Exiting Listener Thread
That's definitely the reason the server won't accept connections now. That is the main connection acceptance thread. I've never seen that error before. I'll take a look at the code and see what could cause that error.

Can you try rebooting the server?

I think I do know what the problem is. Do you have more than 64 IP addresses on the server? 64 is currently the maximum we support. More than that could result in this error.

Currently running with 36 ip addressees spread evenly between 2 NICs, but on the interface side of Cerberus it shows 143 Interfaces. Regarding that .. is there any way to force it to select 1 particular ip and not load all interfaces on startup?

Hello,

Yes, just un-check the IP addresses that you don't want to listen on.

Uncheck an IP listener

Also, on the General page of the Server Manager, make sure IPv6 is not checked (unless you want to use IPv6).


Then, go to the File menu and Exit from the GUI.

Finally, restart the underlying Cerberus FTP Server Windows Service.

Worked like a charm! ... all in all it was an issue of me being lazy :lol: With the old server, (and fewer ip's) I used to uncheck the interfaces I didn't want, mostly out of security reasons but now it just slipped my mind.

Is it possible, in future releases, to add an option to bulk delete interfaces from the menu or include a manual "listen only on" option? Mostly out of convenience if anything. Also, after the 30 day period expires, can I upgrade it directly to a personal edition or it will need to be reinstalled using a different installation kit for that particular version?

I'll see what I can do about bulk delete.

Yes, you can just upgrade to the Personal edition with a license key after your 25-day trial expires (or before). You do not need to reinstall. The evaluation version is the same as the release version. It just needs a valid license key.
