</span>The base16 scripts rely on an obscure XTerm feature-- the OSC<br>
change-color commands. Mosh doesn't support those commands, or pass<br>
them through.<br>
<br>
My best guess is that you have a base16 script set up in your shell<br>
profile/login scripts on both client and server. When you use plain<br>
ssh, everything is fine, because base16 runs both when you start the<br>
client XTerm and when you login to the remote server. When you use<br>
plain Mosh, everything is fine-- because base16 runs when you start the<br>
client XTerm, and the base16 invocation on the server is essentially<br>
discarded by Mosh. When you use cssh with ssh, everything is fine--<br>
cssh starts an XTerm invoking ssh and base16 does not get run there, but<br>
the remote server runs base16 and it's passed through to the XTerm.<br>
When you use cssh with mosh, it breaks-- base16 is not run locally on<br>
the new XTerm and the server's invocation is discarded.<br>
<br>
Unfortunately, implementing this feature is going to be pretty low on<br>
the priority list-- you're the first person to run into this issue that<br>
I know of. A possible workaround is to write a wrapper script that<br>
invokes the base16 script, then runs mosh. Use that as the ssh command<br>
in your .clusterssh/config file. That way, when cssh starts the XTerm,<br>
the base16 script is always run locally. You might even find benefit in<br>
doing this for ssh, ignoring mosh.<br>
<br>
You could also investigate XTerm's XTerm.vt100.color* resources,<br>
documented in the man page, which appear to have the needed<br>
functionality. X resources are horribly archaic, but they should work<br>
reliably for any XTerm you start without requiring any scripting.<br>
