Getting "Connection Refused" message when using sftp

Paul Maglinger — Thu, 23 Apr 2009 14:43:48 GMT

Running 11.23. Trying to connect to remote server using sftp. when I try, I get the following:

#sftp sftp.domainname.com
Connecting to sftp.domainname.com...
ssh: connect to host sftp.domainname.com port 22: Connection refused
Connection closed

I can perform the same command from my Windows workstation and at least get a login prompt. I don't have HIPS or firewall configured on this server. sshd is running. Thoughts anyone?

"Connection refused" normally means that you
can talk to the other system, but that it
isn't running (or willing to run) the
requested server. This normally rules out
basic network/routing problems.

> Thoughts anyone?

Many things are possible. Some clever
firewall could do it.

Which server is "this server"? What's
_between_ the systems?

> sshd is running.

So you claim. (I see no evidence.) On what?

You're hiding the actual commands, so it's
hard to know what you really did, but
"sftp.domainname.com" might mean different
things on the two systems. Specifying an IP
address might change the results.

any chance you're using non-std ports, ie. other than 22?

Take a look at /var/adm/log/syslog.log, there might be some info there.

No HIPS or firewall on mine (the client server). The sftp server is a remote vendor. We have a firewall appliance on our side, but as I can at least get to a login prompt from my Windows workstation, which is on the same domain as the client server, and I can hit it from a SCO box, so I don't believe the appliance is the problem.

It seems to me to be localized to this HP-UX box. I'm just trying to figure out if I missed something obvious.

And yes,

ps -ef | grep sshd
root 1502 1 0 Apr 18 ? 00:00 /opt/ssh/sbin/sshd

Using the ip address made no difference.

Using port 22. Even tried telneting to that port.

syslog didn't show anything out of the ordinary.

This means? (My psychic powers are weak.)

> Using the ip address made no difference.

And you tried using "the ip address" on the
Windows system, too? Showing actual commands
with their actual output (that is, actual
evidence) can be _so_ much clearer than vague
descriptions and interpretations.

> ps -ef | grep sshd
> root 1502 1 0 Apr 18 ? 00:00 /opt/ssh/sbin/sshd

If that's on your local SFTP client system,
then who cares? You're trying to talk to the
sshd on the remote server system. Aren't
you? _That's_ where sshd (or something like
it) needs to be running.

For a good time, you might try (everywhere)
a command like:

telnet 22

where is the name or IP address
of the SFTP server. This would tend to
eliminate some potential client-side SSH
configuration quirks.

"Using port 22. Even tried telneting to that port."

right...that was here:

"ssh: connect to host sftp.domainname.com port 22: Connection refused"

But, what I meant is: is this different from the boxes which work?

You can probably see exactly what you're
doing (and where), and what happens when you
do it, but we non-psychics often can't.
Please try to keep this in mind.

You say that atleast u got login prompt. are u able to login

Please check the time stamp of /var/adm/net*

if it is latest, please give the o/p of the following
netfmt -t -f /var/adm/

Cheers,

Okay, I need the help but I really don't need the sarcasm.

I'm using the IP address now on all my tests to rule out a DNS problem.

I get a login prompt from the remote system when I use Putty on my Windows system, using an IP address.

You were questioning my claim that sshd was running. Apologies for not specifying that I checked it on my system. Doesn't the fact that I could get the login prompt from the remote server on the SCO and Windows boxes indicate that sshd was running on the remote system?

And if I haven't stripped your gears by my previous comments to the point where you won't help me...

From the SCO box:

telnet 65.79.165.194 22
Trying 65.79.165.194...
Connected to 65.79.165.194.
Escape character is '^]'.
SSH-2.0-VShell_2_6_4_448 VShell

From the Windows box:

login as:

From the HP-UX client:

telnet 65.79.165.194 22
Trying...
telnet: Unable to connect to remote host: Connection refused

Hi,

Also please give me the o/p of ssh -v -v server name

and try restarting sshd

/sbin/init.d/secsh stop
/sbin/init.d/secsh start

Cheers,
Ravi.

Hi,

I think the connection is getting refused because of protocal version. Since it working with putty,

I need you to try the following from the hpux client.

ssh -1 hostname
ssh -2 hostname
