I installed cygwin base and admin packages along with openssh on a windows
server. Veritas volume manager 5.1 is also installed on this server. I can
ssh to cygwin and run commands remotely by typing password. But I want to
run commands without password. So I configured .ssh/authorized_keys2 file,
so I can ssh without password. There is no problem in running unix commands
like ls , echo even some EMC symcli commands like sympd list. But when it
comes to veritas volume manager commands , ssh hangs with an error message
that I can't even find on google:

root AT client:/root# ssh winserv  -l iadministrator "vxdisk list"
PBX_Acceptor, cannot connect on \\.\pipe\/tmp/PBXPIPE
{8c7ebc1d-19bd-4d90-9f79-baf15bd318b9}, pipe connect: Input/output error

I need to Ctrl-C to interrupt and when I login to cygwin, ps -ef  shows a
hanging process :,
$ ps -ef
     UID     PID    PPID TTY     STIME COMMAND
  SYSTEM    1800       1   ?  17:26:56 /usr/bin/cygrunsrv
  SYSTEM    4512    1800   ?  17:26:56 /usr/sbin/sshd
  SYSTEM    4908    4512   ?  14:37:14 /usr/sbin/sshd
iadminis    4568    4908   ?  14:37:15 /cygdrive/c/Program
Files/Veritas/Veritas Volume Manager 5.0/vxdisk

even I put vxdisk print in a bash script and run the script with ssh,  I
get the same error.  If I put in the script : vxdisk list >/tmp/list 2>&1
I see this error in /tmp/list and it still hangs.
If I don't use authorized_keys2 file all works fine with typing password.
clients are linux and hpux hosts give the same error.
And only veritas commands give this error, others work fine, Is this a
veritas volume manager cli issue ?
Thanks a lot for reading .
