Unable to send userauth-publickey request after upgrading ssh packages #45

Closed davewood closed 5 years ago

davewood commented 5 years ago

this error appeared after upgrading various ssh related packages on our debian server

/var/log/dpkg.log
2019-03-27 10:59:13 upgrade libssh2-1-dev:amd64 1.4.3-4.1+deb8u1 1.4.3-4.1+deb8u2

updating to v0.70 didnt help. I also tried generating a new key but he same error appears.

Your sample script has 16 lines only!

davewood commented 5 years ago

thats why I added the comment saying which line is #20. I removed host/port variable definitions.

salva commented 5 years ago

That probably means that the remote side is closing the connection because it doesn't like something libssh2 does.

You could try running a sshd server in debug mode and see what it says when you connect to it with libssh2 (for instance, see https://en.wikibooks.org/wiki/OpenSSH/Logging_and_Troubleshooting#Debugging_a_server_configuration).

salva commented 5 years ago

Also, you can recompile libssh2 with debugging support and then activate it in Net::SSH2, and see what comes out.

davewood commented 5 years ago

for the record, connecting with the ssh binary works with the same credentials the script above is using.

davewood commented 5 years ago

remote server says this in /var/log/auth.log

Mar 28 14:28:03 foobar sshd[18007]: Connection closed by 131.xxx.xxx.xxx port 35141 [preauth]
salva commented 5 years ago

Then it is libssh2 closing the socket. Try compiling libssh2 with debugging support as I told you before and see what it says.

rkitover commented 5 years ago

Are these regular RSA keys? Have you tried authenticating with a password to see if it gives the same error?

davewood commented 5 years ago

libssh2 with --enable-debug compiled and $ssh->trace(-1)

libssh version 1.4.3 is very old and completely unreliable. You should upgrade to the latest 1.8.2 version and try again.

davewood commented 5 years ago

we updated to debian 9.8 (libssh 1.7.0) and it works again now.

thank you for your support.
