Mosh: brew installed, bash: mosh-server: command not found...

[yixizhang]

installed the latest version, 1.1.3, tried to run mosh username@server-path, and entered the password, keep receiving the error message: bash: mosh-server: command not found... but checked and pretty sure that mosh-server and mosh-client were installed in the same directory, /usr/local/bin as well.

Hello. Have you installed mosh on the server?

[yixizhang]

oh, should I? that's like a foolishest mistake, didn't see it in the usage description... would you mind point me to the right introduction page? and then this could be closed.

[keithw]

No worries. FWIW, we do discuss this in the README on the front page (https://github.com/keithw/mosh): "Usage: The mosh-client binary must exist on the user's machine, and the mosh-server binary on the remote host."

Please open a new ticket if you have trouble, and thanks for using mosh!

For the record/anyone who finds this one as a search result:
If this happens to you on Gentoo, enable the 'server' USE-flag for the net-misc/mosh package and re-emerge it then.

@keithw Is it possible the error message could be made more clear, to explain where the problem is coming from?

I have the same problem.
I've installed mosh-server on my host machine via mac ports, and I get the same error.
I've tried manually doing
~ mosh-server,
something pops up giving me

MOSH CONNECT 60001 [hidden key]

mosh-server (mosh 1.2.4
[license info]

[mosh-server detached, pid = [pid]]

What's going on?

Same problem here, I can ssh into the Mac and type mosh-server and everything looks as iamchanghyunpark describes. Then when I ssh in using Mosh-Client for Google Chrome, I get

Bad response when running mosh-server: 'bash: mosh-server: command not found

(brew install mobile-shell)

QUICK FIX:

1) Create this script called mymosh in your home folder:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
/usr/local/bin/mosh-server

2) Chmod mymosh to 777

3) In the Google Chrome App extension, when putting your settings, put into the setting for "Mosh Server Command" the following:
./mymosh

For me, this worked.

Since this closed issue seems to be a popular place to go for people with similar symptoms: if you are seeing a message like mosh-server: command not found, you need to make sure that

1. The mosh-server command is installed on the server,
2. The mosh-server command is in your server’s PATH, and
3. The mosh-server command is _still_ in your server’s PATH if you run it directly from the SSH command line. Try these commands:

ssh HOSTNAME 'mosh-server --help'
````

or

ssh HOSTNAME 'echo $PATH'
```

It seems that some systems satisfy (2) but not (3), perhaps because PATH is not being set in the right dotfiles. (I wouldn’t blame you—which dotfiles are executed where can be a confusing system-dependent mess.)

If you don’t want to fix your dotfiles, you can work around this by passing the --server option: mosh --server=/full/path/to/mosh-server HOSTNAME.
