After upgrading a Linux system from OpenSSH 6.7 to 6.9, Cisco switches/routers can no longer scp config files to/from the system. The last debug entry before the Cisco device closes the connection is "debug1: server_input_channel_open: confirm session". The next line is "Connection closed by x.x.x.x". Anyone else seen this or know of a fix? The Cisco device gives "Undefined error" when scp'ing a config file from the server, and "Permission denied" (probably not the correct error message) when scp'ing a file to the server. Works fine after reverting to 6.7. Cisco device is running IOS 15.1(2).
We don't use 'scp' but regular 'ssh' started failing with OpenSSH 6.8. Here's the config in 'ssh_config' that works for us: Host <list of router names / patterns here> ForwardAgent no ForwardX11 no ForwardX11Trusted no Ciphers aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc KexAlgorithms diffie-hellman-group1-sha1 Mike -- Mike Peterson Information Security Analyst - Audit E-mail: mikep@xxxxxxxxxxxxxxx WWW: http://www.noc.utoronto.ca/ Tel: 416-978-5230 Fax: 416-978-6620 _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
