Compiling Mosh (http://mosh.mit.edu/) under Cygwin

mosh-cygwin.md

NOTE: You don't need to compile Mosh on Cygwin yourself anymore; just install the package with Cygwin's setup.exe.

1. Download Cygwin.

2. Run setup.exe and install the following packages in addition to the default ones:

   • make
   • boost
   • libncurses-devel
   • pkg-config
   • perl

3. Download and compile Protocol Buffers (make sure there are no spaces in the working directory when compiling Protocol Buffers, make will fail if there are):

    $ tar zxvf protobuf-2.4.1.tar.gz
    $ cd protobuf-2.4.1
    $ ./configure
    $ make
    $ make install
   

4. Download and compile Mosh:

    $ tar zxvf mosh-1.1.3.tar.gz
    $ cd mosh-1.1.3
    $ ./configure CPPFLAGS="-I/usr/include/ncurses" PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
    $ make
    $ make install
   

5. Install the IO::Pty Perl module:

    $ perl -MCPAN -e shell
    cpan> install IO::Pty
   

6. Rock’n’roll.

@mqhiller is mosh-server installed in your path on 192.168.97.121? If it's installed but not in your path, use the client flag --server=/path/to/mosh-server to specify the path to it. If it's not installed, install it.

This doesn't work for me, it just says, "hangup"

See notes here:
mobile-shell/mosh#164

The problem is that we weren't using mosh correctly. See below. You must log onto the remote host using SSH. Then start mosh-server. This in turn gen's a key and a port. See below. That was the fix for me. Also make sure that you have setup your iptables and/or firewall(s) to allow this traffic through.

Now I run on the server:

mosh-server

MOSH CONNECT 60001 qbE+SNhaEJpfzFpHcXBwkw

and on the client:

MOSH_KEY=qbE+SNhaEJpfzFpHcXBwkw mosh-client 60001

You might also mention that protobuf make will fail if the working directory has spaces in the path.

I'm having an issue where the client immediately hangsup when I try to connect. Any ideas what might be causing this?

What I see is following message.
Hangup

Check your iptables. You must have those port ranges open.

-DG <--- He works out.

@danep2: Will do, thanks!

This mosh configure worked for me:
PKG_CONFIG_PATH="/usr/local/lib/pkgconfig" ./configure CPPFLAGS="-I/usr/include/ncurses"

Current pkg-config (version 0.23b-10) installs to /usr/lib/pkgconfig/.

I also needed to install the zlib-devel and openssl-devel packages.

Thanks for the instructions.

Hmm.. I guess I'll try the older version of this package then..

EDIT: Using the version of this package that was specified above..

Using Cygwin x86_64, btw.

I also needed to install libz-devel and openssl-devel to get mosh to compile, however everything is working quite nicely now. :) Running cygwin x86_64 version 1.7.25(0.270/5/3).

Note to future visitors: you don't need to compile Mosh on Cygwin yourself any more; just install the package with Cygwin's setup.exe.

Above instructions is outdated, and the mosh in Cygwin official packages is broken. Instructions to build are here: mobile-shell/mosh#850 (comment)

1. Can't download a .gz. The "Protocol Buffers" link points to a git repository! Since you're supposedly inside cygwin (not a fancy GUI desktop with a full-fledged web browser), you can't access the "download ZIP" option, so you're left with cloning a git repository, so no ".gz", nor useful instructions after that.
   git clone https://github.com/protocolbuffers/protobuf.git --depth=1

./configure
$ make
$ make install

It's all Ancient Mesopotamian dialect for me. I just wanted to install mosh for Windows, not learn to compile (Python, maybe?) under a completely new interface (cygwin, a pseudo Linux that doesn't work exactly as a ny Linux distro) that demands a obnoxiuslt steep learning curve just to use once.
