Abnormal Disconnect

[Brian_Davies]

Upgraded to 1.6.6 Core Shell and Helper 4 but am now getting an Abnormal Disconnect (did not before). This is on all saved locations. I deleted and tried reading a location and no change.

Example:
> 10:43:58 ----------------------------------------

> 10:43:58 Equivalent Command: ssh -tt -o ServerAliveInterval=15 -o ConnectTimeout=15 -o ExitOnForwardFailure=yes -o ServerAliveCountMax=3 -o CheckHostIP=yes axxxadmin@10.1.100.2xx

> 10:43:58 Connecting…

> 10:43:58 Using Core Helper 4.0 (r40)

> 10:43:58 Authenticating…

> 10:43:58 Unable to negotiate with 10.1.100.2xx port 22: no matching cipher found. Their offer: aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc

> 10:43:58 Abnormal Disconnect

Hi, sorry about the problem. Could you please set log level to DEBUG3 and paste the log again?

Enable logging

The default logging level is set to Info, Debug1, Debug2 and Debug3 each specify higher levels of verbose output. [image] Core Shell Open or go to Hosts tab, right click on the host and select Edit Settings… from context menu, navigate to Connection tab, then scroll down to Log Level option. Press ⌘ I (or select Shell -> Show Inspector from main menu) reveals shell session information, as well as log content. [image] Core Tunnel Navigate to tunnel's Settings…, Connection tab, then scrol…

Thanks

Could you please paste the equivalent command in a local shell and try again?

ssh -tt -4 -vvv -o ServerAliveCountMax=3 -o ConnectTimeout=15 -o ServerAliveInterval=15 -o CheckHostIP=yes -o ExitOnForwardFailure=yes acdsadmin@10.1.100.24

It seems there is a config error in /etc/ssh/ssh_config or ~/.ssh/config, could you please also paste your configuration here?

Thank you.
