Hello All,

I'm new to OpenVMS. Looking through my logs, I noticed the following messages:


%%%%% OPCOM 25-APR-2016 17:42:34.54 %%%%
Message from user SYSTEM on [OpenVMS Server]
MultiNet Server: R_Services: malformed from address (from 172.71.61.18, port=3935)

%%%%% OPCOM 25-APR-2016 17:42:34.58 %%%%
Message from user SYSTEM on [OpenVMS Server]
MultiNet Server: Service IMAP pid 20c35cd3 failed: file write error


Help!! - How do I resolve this? -- Any help is greatly appreciated.

And if all fails, I can filter out 172.71.61.18 from talking to my OpenVMS server.


Cheers,
Tomas

172.71.x.x is outside the range of 172.16 to 172.32 reserved for local intranets per RFC 1918, so is either in your allocated address space, or you are exposing your VMS system to the public Internet.
(Or you have a mis-configuration of your intranet)

If your system is exposed to the public Internet, with out a firewall, then you are going to get continuously probed for security holes. These probes can use up a lot of system resources, and might actually find a security hole, or if the attacker can not find a security hole, may try a DDOS.

I strongly recommend that you have some sort of firewall appliance that will handle the probes.

People on the comp.os.vms newsgroup may be able to offer more specific information about multinet.

HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?
