[Buildroot] ssh connection: connection refused?

[Buildroot] ssh connection: connection refused?

[cem akpolat]

Dear all,

I set the root passwod of the file system in the menuconfig and establish a
ssh connection to my file system. Some ssh keys are generated as below, but
then I couldn't connect second time to the file system. it results in
"connection refused". What could be the principal reason underlying this
issue?


-rw-r--r--  1 root    root      1574 May 26 11:10 ssh_config
-rw-------  1 root    root       668 May 26 19:15 ssh_host_dsa_key
-rw-r--r--  1 root    root       590 May 26 19:15 ssh_host_dsa_key.pub
-rw-------  1 root    root       227 May 26 19:15 ssh_host_ecdsa_key
-rw-r--r--  1 root    root       162 May 26 19:15 ssh_host_ecdsa_key.pub
-rw-------  1 root    root       411 May 26 19:24 ssh_host_ed25519_key
-rw-------  1 root    root        96 May 26 19:24 ssh_host_ed25519_key.pub
-rw-------  1 root    root       965 May 26 19:15 ssh_host_key
-rw-r--r--  1 root    root       630 May 26 19:15 ssh_host_key.pub
-rw-------  1 root    root      1679 May 26 19:15 ssh_host_rsa_key
-rw-r--r--  1 root    root       382 May 26 19:15 ssh_host_rsa_key.pub
-rw-r--r--  1 root    root      3622 May 26 11:10 sshd_config

thanks for your recommendation,

The SSH server is not running.

Which SSH server are you using? Buildroot has support for Dropbear and
OpenSSH, and both packages have init scripts to start the server at
boot time.

Best regards,

Thomas

[Buildroot] ssh connection: connection refused?

Dear Thomas,

I am using both, dropbear and openssh. If using together leads to the
conflict, I should disable one of them. By the way, I can boot first time
the file system, I can login via ssh, but the second time I cannot and
receive "connection refused". I have right now two init scripts under
init.d. One for dropbear S50dropbear and the other for probably openssh
S50sshd.

Thanks,
Cem

Of course it leads to a conflict (though I believe one of them should
start successfully, and the other fail).

Please chose one or the other. Having two SSH servers listening on the
same TCP port doesn't make any sense.
