FTP server will not start??

Post by willemgrooters » Mon Sep 20, 2021 3:51 pm

I have FTP enabled via TCPIP$CONFIG, and was able to pass files in both directions.
After a reboot, - with no changes in configuration - FTP service is not enabled, so the system cannot be accessed for file transfer:

Code: Select all

$ tcpip sho serv ftp

Service             Port  Proto    Process          Address            State

FTP                   21  TCP      TCPIP$FTP        0.0.0.0             Disabled
$
The reason is in the logfile:

Code: Select all

$ type sys$sysdevice:[tcpip$ftp]tcpip$ftp_run.log
%DCL-E-NOCMDPROC, error opening captive command procedure - access denied
  TCPIP$FTP    job terminated at 20-SEP-2021 19:15:11.15

  Accounting information:
  Buffered I/O count:                 29      Peak working set size:       2160
  Direct I/O count:                   18      Peak virtual size:         172864
  Page faults:                       154      Mounted volumes:                0
  Charged CPU time:        0 00:00:00.03      Elapsed time:       0 00:00:00.16
$
Enabling the service doesn't work either:

Code: Select all

$ tcpip ena serv ftp
$ tcpip sho serv ftp

Service             Port  Proto    Process          Address            State

FTP                   21  TCP      TCPIP$FTP        0.0.0.0             Disabled
$
FTP seems started normally on reboot:
...
%TCPIP-S-STARTDONE, TCPIP$FTP startup completed
%TCPIP-S-STARTDONE, TCPIP$FTP_CLIENT startup completed
...
Other services that seem to have a similar behaviour are NTP and XDM: Both seem to have started according messages in boot, but both services are (and remain) disabled.

The word, "captive" bothers me. Seems like wrong account booted under.
I would think SYSTEM would start TCPIP services.

So does the previous boot and thus log file reveal anything different? tcpip$ftp_run.log;-1?

It would seem to go nuclear and delete the service and re-enable it would be over the top. It seems
there should be more of an obvious cause.

Could go into AUTHORIZE, check TCPIP$FTP as an account .... see where it is start from .... see how it compares to
other TCPIP services defined in AUTHORIZE.

UAF> sho TCPIP$FTP

check UIC

At boot, SYSTEM will start TCPIP services, but the daemons run under separate, non-privileged, accounts.

On my system, the tcpip$ftp is flagged restricted, not captive (and also limited to network access only). My first step would be to make sure the lgicmd command procedure exists (default is "LOGIN") and is readable by the tcpip$ftp account, then make sure LOGIN was not defined as a logical name.

Let me to suggest you to check the security profile of sys$manager:sylogin.com :

$ dir/sec sys$manager:sylogin.com

Directory SYS$COMMON:[SYSMGR]

SYLOGIN.COM;14 [SYSTEM] (RWED,RWED,RE,RE)

Total of 1 file.

Make sure that WORLD=RE.

If not, then

$ set sec/class=file/prot=(w:re)/log sys$manager:sylogin.com

Keep me updated.

Thanks Maurizio - that indeed was wrong.

Enabled the services (FTP, NTP and XDM, these were all disabled but should work):

Code: Select all

$ TCPIP ENA SERV <service>
did the trick with NTP and XDM, for FTP, it needed to be started as well:

Code: Select all

$ @SYS$STARTUP:TCPIP$FTP_STARTUP

Maurizio,

it should be noted, that WO:E is sufficient, to execute a DCL procedure (or image), if there is no need to be able to look at the contents of the procedure/image.
