problems in connection Open VMS to Unix using SFTP
I am using the following command but the system is not asking for the password to connect for the first time, where as other accounts are working properly on the same server.
sftp userid@ipaddress
below is the error:
Warning: child process (/sys$system/tcpip$ssh_ssh2) exited with code 196.
%TCPIP-E-SSH_FC_ERROR, error in ssh file transfer operation
Notes:
As per the server hosting team there are no difference between the accounts on the server.
Questions:
1. If the accounts are same why we are getting the error "child process (/sys$system/tcpip$ssh_ssh2) exited with code 196."
What changes are required in the account setup to avoid the above error.
2. Is there any way to generate the keys from one account and use the same from other account to remediate the above problem.

Re: problems in connection Open VMS to Unix using SFTP
which versions of vms and tcpip services are in use here ?
have you tried using the "-D" option to get more information on where it is failing ?
personally i would always use quotes around username@system strings to go to a unix server,
do you need it to be password auth ? using private / public keys is a lot easier and a bit more secure.
the openvms ssh manual is here for all the methods available and how to implement them :-

I know nothing, but:
ALP $ exit 196
%SYSTEM-F-GPTFULL, global page table is full
help /message GPTFULL
write sys$output f$getsyi( "free_gblpages")

Re: problems in connection Open VMS to Unix using SFTP
I had a problem with a UNIX machine logging in to an OpenVMS machine using sftp. I dont remember exactly what the error code was, but I do remember the "Warning: child process exited..." messages (although these may be generic).
The OpenVMS machine was a BL860c running OpenVMS 8.3-1H1 and TCPIP Services 5.6 ECO3.
The problem turned out to be related to the LENGTH of the Username and the LENGTH of the Login Directory. If either or both of these had length=12 (char) then the sftp login would fail.
When you run out of hair, ask HP about this.
Dave.

Re: problems in connection Open VMS to Unix using SFTP
no, but you can try using scp
scp dev:[dir]file "user@ipaddress:dir/file"

Our not knowing the probabilities does not
make them equal.
Another datum of questionable significance:
ALP $ search decc_include:errno.h ERRNO_MAX
#define __ERRNO_MAX 88 /* MUST equal largest errno value */

Re: problems in connection Open VMS to Unix using SFTP
can you post the quotas from that VMS user and have you tried another VMS username?
Have you reported this to HP?
Purely Personal Opinion
