Mosh: Problem running mosh-server on OS X

[jiyinyiyong]

I installed Mosh on an iMac:

➤➤ uname -a

[mosh-server detached, pid = 11214]

and try to connect from my Macbook(10.8.4, Mosh works well here):

➤➤ uname -a
Darwin C-Air.local 12.4.1 Darwin Kernel Version 12.4.1: Tue May 21 17:04:50 PDT 2013; root:xnu-2050.40.51~1/RELEASE_X86_64 x86_64

Password:
bash: mosh-server: command not found
Connection to 192.168.1.11 closed.
/usr/local/bin/mosh: Did not find mosh server startup message.

Then I went back to check on iMac, there was a mosh-server running (soon it disappeard, though):

➤➤ ps aux | grep mosh
C          11271   0.0  0.0  2432768    596 s001  R+    6:33PM   0:00.00 grep mosh
C          11266   0.0  0.0  2434268   1500 s001  S     6:33PM   0:00.00 mosh-server

That's strange. Doesn't Mosh server work on OS X?

[andersk]

mosh-server is an internal command that you should never run yourself. The mosh client will take care of running it on the server for you. However, mosh needs to know where to find it on the server. You can do this either by making sure mosh-server is in your PATH, or by passing the --server=/path/to/mosh-server option to mosh.

[jiyinyiyong]

@andersk You are right. It works now with --server= parameter.

[mosh is exiting.]

But what I'm still confused about is mosh-server is in my $PATH, why that happened?

A-iMac:~ C$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

Same problem. I have OSX Mavericks and mosh installed via brew ($ brew install mosh).
But I still can't connect to my Mac with mosh without --server=/usr/bin/local/mosh-server

[andersk]

Your PATH appears to be set differently in interactive and noninteractive shells. Try these commands to see the difference:

ssh SERVER
echo "$PATH"

and

ssh SERVER 'echo "$PATH"'

[TheMengzor]

OMG IT WORKS! Thanks!
Solution for OSX is (on remote host under ssh login user):

echo "export PATH=$PATH:/usr/local/bin" >> ~/.bashrc

Had the same problem with zsh, need to set path in .zshenv

use
echo "export PATH=$PATH:/usr/local/bin" >> ~/.zshenv
