I'm upgrading my systems from Slackware-10.2 to Slackware-11.0 and have come across a ssh/scp error that I cannot resolve.
The network has one server/workstation (running Slackware-11.0 with a 2.6.19.2 kernel), one notebook (running Slackware-11.0 with a 2.6.18.6 kernel), and one laptop (running Slackware-10.2 with a 2.4.31 kernel). The desktop (server/workstation) can ssh/scp to both portables. Permissions are correct (0700 for ~/.ssh and 0600 for the files in that directory) on all machines. The two portables can ssh/scp between themselves. Neither portable can ssh/scp to the desktop. The error is "ssh_exchange_identification: Connection closed by remote host." Invoking ssh with the '-vv' option does not provide me with any greater insight: OpenSSH_4.4p1, OpenSSL 0.9.8d 28 Sep 2006 debug1: Reading configuration data /etc/ssh/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to salmo [192.168.55.1] port 22. debug1: Connection established. debug1: identity file /home/rshepard/.ssh/identity type -1 debug1: identity file /home/rshepard/.ssh/id_rsa type -1 debug2: key_type_from_name: unknown key type '-----BEGIN' debug2: key_type_from_name: unknown key type 'Proc-Type:' debug2: key_type_from_name: unknown key type 'DEK-Info:' debug2: key_type_from_name: unknown key type '-----END' debug1: identity file /home/rshepard/.ssh/id_dsa type 2 ssh_exchange_identification: Connection closed by remote host Google reveals others having this problem in the past, but nothing I saw helped me. I'd greatly appreciate some insight. Rich -- Richard B.
