sftp problem

 

When I run sftp, I get no output whatsoever, not even an error message. How do i diagnose this? hp-ux 11.31

 

 ssh -v                                                                       #06/16/15 9:38AM#
OpenSSH_6.2p1+sftpfilecontrol-v1.3-hpn13v12, OpenSSL 0.9.8y 5 Feb 2013
HP-UX Secure Shell-A.06.20.006, HP-UX Secure Shell version

 

# /opt/ssh/bin/sftp -v  -v -v  xxx.xxx.xx.xx

   On what?

 

      uname -a

 

> OpenSSH_6.2p1+sftpfilecontrol-v1.3-hpn13v12, OpenSSL 0.9.8y 5 Feb 2013

 

   Newer than mine, so I know nothing, but...

 

> When I run sftp, I get no output whatsoever, [...]

 

   For how long?  True for all servers, or only "xxx.xxx.xx.xx"?  For
all users?  (Is "xxx.xxx.xx.xx" an IP address?)

 

      truss /opt/ssh/bin/sftp -vvv xxx.xxx.xx.xx

True for all users, for all target computers.

 

I have copied sshd_config and ssh_config from another machine, restarted ssh to no avail.

Sometimes I get this in reply:

 

Connection closed

   Still wondering.

   You really tried _all_ possible target computers?  How many was

that?

   Why? Were they different?  I would not expect "sshd*" to affect
greatly a _client_ problem.

 

> restarted ssh

 

   Which means what, exactly?  As usual, showing actual commands with

their actual output can be more helpful than vague descriptions or
interpretations.

   Can you communicate with "xxx.xxx.xx.xx" (whatever that is) in any
other way (FTP, ssh, Telnet, ...)?

Re: sftp problem

The problem was that the ssh file was set to 0 in size. Strange. I copied a working ssh file and all is working.

 

Also there were multiple versions of ssh on the system, but apparently the necessary one was null in size.
