[daip] remote tape mounts

[Joseph Lazio]

Hi, 

31DEC06 (pre-compiled binaries) on Linux systems


On the machine hosting the tape drive:

 aips% mt -f /dev/nst0 status
 SCSI 2 tape drive:
 File number=0, block number=0, partition=0.
 Tape block size 0 bytes. Density code 0x24 (DDS-2).
 Soft error count since last status=0
 General status bits on (45010000):
  BOT WR_PROT ONLINE IM_REP_EN

So that looks good.


On the remote machine, fire up AIPS: 

>inp mount
AIPS 2: MOUNT:    Verb to software mount a tape
AIPS 2: Adverbs     Values                 Comments
AIPS 2: ----------------------------------------------------------------
AIPS 2: INTAPE        1                    Tape unit # (0=> 1)
AIPS 2: DENSITY    6250                    Density to set on mount.
AIPS 2: REMHOST    'CRAZYHORSE'               Remote computer name
AIPS 2: REMTAPE       1                    Remote tape drive number
>mount
AIPS 2: ZMOUNR: UNABLE TO MOUNT REMOTE TAPE DEVICE, ERROR   96
AIPS 2: AMOUNT: TAPE IS ALREADY MOUNTED BY TPMON


Looking through errno.h, system error 96 indicates 

#define EPFNOSUPPORT    96      /* Protocol family not supported */


On both machines, TPMON1 is running and /etc/services has the
appropriate definitions for service aipsmt1 on TCP port 5011.



Is this because we are running pre-compiled binaries or is something
else funky going on here?

Thanks in advance,
