I just have a general question here,I have a server that initiates a connection out to the internet to do a FTPS on port 990 I see the initail connection on port 990 happening but I don't see the data port 989 is the problem on the distant end or is it on my end the near end? I was thinking it has to be the distant end beause I am logged into their box and authenticated and I do see 990 open but the data port 989 I never see.
Hi ok at least we are moving in the right direction. I can now connect to port 990 but the data port 989 isn't working. Unable to transfer files or do a simple directory. Both ports are open on the firewall and I do see on port 990 the hitcount go up but not on port 989
We have resolved the issue, this is what we did to fix the FTPS issue.
When using FTPS to connect on ports 990 and 989 we can make the initial connection to port 990 but the data port 989 doesn't work. Symptoms are we cannot do a file transfer or do a simple directory lookup.
Instead of opening up the data port 989 what was done to fix it was use a random port of anything higher than 1024. In this case we used port 22333 and changed on the server to listen to port 22333 instead of 989. When we attempted to connect, port 990 worked as usual and then data port 22333 work and we where able to transfer files.
So in short what worked for me for FTPS was using the normal port of
Yeah I know I thought it was a silly idea as it didn't make much sense. Everything I read said to use port 990 and 989. Not sure why that didn't work or what I was doing wrong but this seemed to work and we are ftps with out issues now. Thank you for your help on this...much appreciated!!!!!
