No prob with the destination ip. The problem is sftp itself not work.
Even if I type sftp without ip, it will prompt to #

At the prompt do:

# type sftp

Note that 'type' is a command. Do just as it appears above.

Check the size of the 'sftp' executable as well. It could have somehow gotten corrupted.

Yes sftp size is 0

Here's your problem. The sftp binary is 0 bytes in size. You need to restore it from a backup.

Ok done now as root I can sftp but not as other user.
Where to set permission? I have compare with other server no diff.

Re: sftp not working

Fauziah Mahdan — Wed, 09 Mar 2011 07:28:36 GMT

ok I found the diff when I compare a-z between 2 servers

executable permission for other for file ssh under /opt/ssh is missing for this server
drwxr-x--- 12 bin bin 8192 Oct 22 2008 ssh

After give permission then other user can use sftp.

Infact all file under /opt is without executebale for other compare to another server. No wonder from syslog I found cimserver for this server also not running.

Thanks all.

Hi,

let's run an swverify to check if you have other issues...

# swverify \*

This will check if the installed files were modified since the install.
