[Gumstix-users] Is anyone else having this problem using scp and ssh on the gumstix?

[David I S Mandala]

I can ssh into the gumstix with no problems and I can scp files into the
gumstix again with no problems. But when I'm on the gumstix and I try to
scp a file out or ssh out I get the following errors:

# scp test.txt 192.168.254.200:.
/usr/bin/dbclient: No such file or directory
lost connection

# ssh david192.168.254.200

Host '192.168.254.200' is not in the trusted hosts file.
(fingerprint sha1
40:00:d8:a7:a3:13:55:44:a2:eb:5f:19:0e:0f:29:fc:8a:6b:42:ca)
Do you want to continue connecting? (y/n)
yes
ssh: connection to ***@192.168.254.200:22 exited: No auth methods could
be used.

Is anyone else having these problems? Any suggestions what to do to fix
this?

TIA

Yeah, I had the same problem.

dbclient is the dropbear ssh client program. It needs to be created as a
link to the main dropbear binary. (I don't know why this does not happen
in the buildroot)

i did the following (on the gumstix):
ln -s /usr/sbin/dropbear /usr/bin/dbclient

After that it worked fine.

Still could not get it to do key based logins though...

Phil,

Thanks that helped, I put the symlink in. That changed the symptoms but
still did not resolve the problem completely.

Now when I scp the test file I get:

# scp wireless ***@192.168.254.200:.
WARNING: Ignoring unknown argument '-x'
WARNING: Ignoring unknown argument '-oForwardAgent no'
WARNING: Ignoring unknown argument '-oClearAllForwardings yes'
/usr/bin/dbclient: connection to ***@192.168.254.200:22 exited: No
auth methods could be used.
lost connection
#

and when I attempt to ssh I get:

# ssh ***@192.168.254.200
ssh: connection to ***@192.168.254.200:22 exited: No auth methods
could be used.

I can still ssh and scp inbound however.

Anyone else have any ideas, suggestions?

TIA

David

Hi David.

Are you trying to use password or key based authentication?

What do the logs on your server machine say when the scp or the ssh from
the gumstix fails?

Phil

[David I S Mandala]

Phil,

I did a test with both password and a dsa key. I can ssh into the server
from any of my other machines so the problem is not at the server end.

The result on the gumstix is consistent.

# ssh ***@192.168.254.200
ssh: connection to ***@192.168.254.200:22 exited: No auth methods
could be used.

Log output below:

Password.

Below is everything in the log once I restarted sshd with debugging set
on.

Hi David.
Are you trying to use password or key based authentication?
What do the logs on your server machine say when the scp or the ssh from
the gumstix fails?
