Can connect via SSH, but via SFTP

Andrew Kaplan — Wed, 04 Apr 2007 12:00:55 GMT

Hi there --

I have the HP Secure-Shell 4.20 application installed on an 11.00 system, and while I can connect via SSH, I cannot do the same via SFTP. I checked the sshd_config file, and the following line exists in the file:

Subsystem sftp /opt/ssh/libexec/sftp-server

Is there something else that needs to be configured or activated in order for SFTP to work? Thanks.

do you see anything in your syslog that would help troubleshoot?

Shalom,

The default configuration should do the trick.

You may wish to check another clean system to see if sshd_config has been changed.

syslog is also a good idea.

Hi there --

The only reference to SFTP is a line that reads as follows:

subsystem request for sftp

There aren't any followup messages to it.

We don't have any machines with a similar configuration, so I can't make a comparision to another.

edit your sshd_config file and uncomment the line

#LogSftp no

and chge it to yes like so:

LogSftp yes

and uncomment change

#SftpLogLevel INFO

then stop and start sshd. then look at your syslog messages. hopefully something more useful shows up.

Also, can anyone sftp, or is every user account having this issue? you might try creating another account and testing it.

I made the changes that were suggested, and after restarting ssh I attempted to use sftp again. The error messages I saw in the syslog file were as follows:

try installing patch PHCO_34806.

you could check /opt/ssh/newconfig/opt/ssh/etc/sshd_config and compare this with your active sshd_config.

especially on the UsePAM and ChallengeResponseAuthentication remarks
i'm not sure but it is worth a try

Hi there --

I installed patch PHCO_84806 and also ran the diff command on the /opt/ssh/etc/sshd_config and the /opt/ssh/newconfig/opt/ssh/etc/sshd_config files, and there wre no apparent differences between the two.

The SFTP capability is still not working. Does anyone have any other ideas? Thanks.
