OpenVMS FTP Not Working
Posted on 2006-06-23
Advance apologies: I know just enough about VMS to be dangerous. I hope this is the correct location to post this question as I couldn't find a VMS-specific topic.
On to the problem. We have a VAX attached to an analytical instrument that just collects data. Until recently, we've been able to FTP the data from the VAX to a PC, with the VAX as the FTP server. Then it started failing sporadically. Now it doesn't work at all. The symptom: On the PC at the command prompt we type: FTP [VAX_name]. The VAX responds: Connected to [VAX_name]. Then there is a long pause and finally this message appears: Connection closed by remote host. As far as I can determine, there have not been any changes made to the system, but I am suspicious of these denials.
With my limited knowledge, I poked around a bit on the VAX and ran: UCX>SHOW SERVICE FTP/FULL. FTP is enabled, but some of the information concerns me. The port is 21, protocol = TCP, but the address is 0.0.0.0. Is this right? If not, how do I change it?
Also, under the Security heading, Accept Host and Accept Network addresses are both 0.0.0.0. Could this be part of the problem?
