sftp

[Jie Li]

Hi, Folks:

I try to use WinSCP2 to connect to the HP UX server, however I keep getting the message " Error detecting variable containing return code of last command." I have OpenSSH2 installed on the server.

Also I read something about "run SFTP on the server. It is best to run it as a SSH2 subsystem." How do I find out if SFTP is running on the server? How can I run it as a subsystem of SSH2?

Thanks a lot

Did you install "HP Secure Shell"?

ps -ef |grep ssh
root 8615 1 0 Aug 19 ? 0:00 /opt/ssh/sbin/sshd

Release notes:
http://docs.hp.com/hpux/onlinedocs/T1471-90011/T1471-90011.html


Secure Shell can be downloaded here:

[Jie Li]

Yes. The security shell was installed. It is ssh2.

[Rick Garland]

If the Secure Shell (ssh) is installed and running on the system you will have sftp.

ps -ef | grep ssh

Will return a line indicating sshd if installed and running.

If the package is installed I believe the depot installs in /etc/opt - you should see a ssh directory.

[Geoff Wild]

If you installed HP's version, you should have:

/sbin/init.d/secsh

It starts in:

/sbin/rc2.d/S393secsh

When I do ps -ef | grep ssh, I see:
root 1114 1 0 Aug 9 ? 4:01 sshd

However I couldn't find ssh under /etc/opt.

[Jie Li]

Couldn't find:
/sbin/init.d/secsh
/sbin/rc2.d/S393secsh

The ssh we have on the server is OpenSSH2.

[Geoff Wild]

Okay - so you didn't install HP's version - you will have to check out http://www.openssh.org/

In particular, the FAQ:

http://www.openssh.org/faq.html

There's some info on sftp...

[Rick Garland]

Look at doing a find

# find / -name "ssh*" -print

This command is not probably not the most efficient search but it will get the job done. Depending on size of system and disks, hopefully won't create much overhead.

Once located you can scan the directory.

One thought is you do not have the ssh directory in your PATH - if it is true that it is not HP's ssh.

From your ps -ef output the daemon is running.

[Muthukumar_5]

SFTP binary is executed with the sshd(aemon) support. It will be ready when the sshd deamon running there. We can find them with process status command of ps

simply as ps -ef | grep -v grep | grep sshd

And if you want to run the ssh as ssh2 then,

we have to change the sshd_config setting of protocol version as,

protocol 2,1

so that it will work as protocol version 2 first ( ssh2 ) then it will be as 1 if ssh2 can not be executed.

Restart the sshd now! You are ready to run sftp with ssh2 sub system.. that is it.

I saw the following in my config file for SSH.
"Subsystem sftp /opt/openssh2/libexec/sftp-server" I know we are on SSH2, and we have been using SSH2 client successfully for a long time. It just won't work with the sftp client(WinSCP2) on my pc. Would you please recommend a client to me?

[Rick Garland]

On the WIN side, what SSH application are you using?

There is putty that has the sftp and scp and ssh clients all there. They are called different names but it is still a free download.

[Jie Li]

WinSCP2, I think it is a putty.

[Rick Garland]

Will 'scp' transfers work?

[Jie Li]

I couldn't get it to work. When I try use it to connect to the server, the error message says "Error detecting variable containing return code of last command."

[Jie Li]

Ok I downloaded a new version of SFTP client. Now it gave me another error message:
"Cannot get real path for '.'.
Permission denied.
Error code: 3
Error message from server: Permission denied
Request code: 16"

[Jie Li]

It is working now.

Thanks for all your help.
