The Question is:
I have three similar Alpha systems on a network and only two of them will
accept FTP requests. I have not been able to identify a significant
difference on the system that refuses a connection. This system accepts
telnet connections and is able to act a
s an FTP client to other systems. The above error messages show on the
operator's terminal when a user attempts a connection. UCX$FTPD exits almost
immediately after starting. The auxiliary server shows a priviledge error.
Why would UCX$FTPD exit and
how do I identify the resource that is causing the priviledge error?
The Answer is :
This configuration of TCP/IP Services on this OpenVMS Alpha version
is not supported and not recommended, please move to TCP/IP Services
V5.1 with ECO, and to OpenVMS Alpha V7.1-2, to V7.2-2, or later.
There have been numerous enhancements and updates made to TCP/IP
Services (and to OpenVMS) since this configuration was released.
Certain errors similar to this have been seen when (very old, and quite
corrupt) ucx$configuration.dat and/or ucx$service.dat files are (re)used
with TCP/IP Services V4.1. The typical approach used to recover from
this is to upgrade to a more current product version, or to delete these
two files and to re-run UCX$CONFIG (which will then recreate the files).
Additionally, security settings on various files can trigger privilege
errors such as shown here -- OpenVMS system security auditing can often
be used to locate the cause of these file access errors.
