Hi. I am on ArchLinux and #13 is exactly the parameter to fix this for me. So it is not an OSX issue. Maybe it has to do with specific versions of ADB. However with #13 merged it works like a charm.

That's odd.
Does adding a "sleep 1" in various places of the script help?

@divVerent I couldn't get any different result. But can you enlighten me about my question regarding the login name and key? Following the basic directions on the readme, my computer would be trying to do an ssh login using my macOS username. I tried various things like the SSHelper app's name com.arachnoid.sshelper or the result of whoami upon login with adb shell, which was just the name shell. Wouldn't I also need to get the SSH key into the appropriate place for that user? I thought some hangup there was causing it to silently fail.

As for the sleep not helping - interesting, because you said running the
same commands manually does work.
I have a suspicion what this might be, but I am not entirely sure. Can you
use ssh with more -v flags? Can you log in when you use adb forward
manually to a TCP port?
As for which username: this is a SSHelper question, and I don't quite
remember the answer to it. IIRC it lets you use any username - but just in
case, I remember some SSH apps somewhere using "user@", "root@" too, so try
these as well. It's certainly not "shell". Installing the SSH key with
ssh-copy-id should work fine.

Since running the commands in adb-channel manually seems to work, I assumed the problem was with SSH and ProxyCommand. I am not sure how to log in (and ultimately run rsync) using just adb-channel but not in the context of ProxyCommand. I don't think I can somehow specify the local socket like I can a port?
For example, if I modify adb-channel to skip the socket creation and only do the following:
adb shell am start -W com.arachnoid.sshelper/.SSHelperActivity
adb forward tcp:2224 tcp:2222
sleep 100
I am then able to in a separate tab log in via ssh -p2224 localhost and I get this prompt (Apparently you're right the username doesn't matter.):
u0_a58@angler:/data/data/com.arachnoid.sshelper/home $
I don't fully understand the merits of the socket versus port, or how to properly use this with ProxyCommand even if using two ports is fine. The script simply exits after the sleep since I commented out the socat that normally kept running. Add an infinite loop and rely on the trap exit?

So I can see that either adb or socat must have corrupted data during the
forwarding.
The merit of using a unix socket rather than a TCP port is that it's easier
to create a temporary one, and it's also more secure (as other users on the
same computer cannot access it).
Let's try one more thing:
- Use a tcp based adb forward.
- But instead of ssh -p2224 localhost, run:
ssh -oProxyCommand='socat stdio tcp:connect:localhost:2224/' sshelper
If this now fails too, we know it's socat corrupting the data - if this
works, adb is the likely suspect.

I appreciate your prompt help, so I'm posting this first before trying to understand better... I am a little unclear on what you're asking me to try. Running ssh ... sshelper would trigger my config that runs the existing ProxyCommand that uses my modified adb-channel... that didn't seem right. So maybe you just meant for me to first run adb forward tcp:2224 tcp:2222 and then your suggested ssh command? But maybe you meant localhost at the end instead of sshelper?

I don't fully understand the merits of the socket versus port, or how to
properly use this with ProxyCommand even if using two ports is fine. The
script simply exits after the sleep since I commented out the socat that
normally kept running. Add an infinite loop and rely on the trap exit?

Okay, so this is odd, as there's clearly an issue with adb then.
I think I'll add a workaround to adb-channel to use a TCP socket on OSX, or
something along these lines.

Thanks.
So I can see that either adb or socat must have corrupted data during the
forwarding.
The merit of using a unix socket rather than a TCP port is that it's
easier to create a temporary one, and it's also more secure (as other users
on the same computer cannot access it).
Let's try one more thing:
- Use a tcp based adb forward.
- But instead of ssh -p2224 localhost, run:
ssh -oProxyCommand='socat stdio tcp:localhost:2224'
Does that break it again? If so, it's socat - of not, it's adb.

Since running the commands in adb-channel manually seems to work, I
assumed the problem was with SSH and ProxyCommand. I am not sure how to
log in (and ultimately run rsync) using just adb-channel but not in the
context of ProxyCommand. I don't think I can somehow specify the local
socket like I can a port?
For example, if I modify adb-channel to skip the socket creation and only
do the following:
adb shell am start -W com.arachnoid.sshelper/.
SSHelperActivity
adb forward tcp:2224 tcp:2222
sleep 100
I am then able to in a separate tab log in via ssh -p2224 localhost and I
get this prompt (Apparently you're right the username doesn't matter.):
***@***.***:/data/data/com.arachnoid.sshelper/home $
I don't fully understand the merits of the socket versus port, or how to
properly use this with ProxyCommand even if using two ports is fine. The
script simply exits after the sleep since I commented out the socat that
normally kept running. Add an infinite loop and rely on the trap exit?

I'm not sure if it helps, but I was trying to understand better what the difference was between the failed connection over the socket and the successful one over TCP port. My understanding of socat, etc., is still very limited, but I was at least able to determine Android is sending a "Protocol mismatch" message right before that "Bad packet length" error.
2017/04/12 13:19:32 socat[93280] I transferred 19 bytes from 5 to 1
2017/04/12 13:19:32 socat[93280] D data loop: sock1->eof=0, sock2->eof=0, closing=0, wasaction=1, total_to={0.000000}
2017/04/12 13:19:32 socat[93280] D select(6, &0x21, &0x2, &0x0, NULL/0.000000)
2017/04/12 13:19:32 socat[93280] D select -> (, 0x0, 0x2, 0x0, NULL/0.000000), 1
2017/04/12 13:19:32 socat[93280] D data loop: sock1->eof=0, sock2->eof=0, closing=0, wasaction=1, total_to={0.000000}
Bad packet length 1349676916.
- Socket listen to failed SSH connection (Protocol mismatch) over ADB forwarded socket to Android
- TCPDump of SSH connection over ADB forwarded port to Android
I was trying to see if there was some setting for socat that would help and looked at what calls adb was using to set up the socket, but it's all still over my head!

I pushed a change to a new branch "adb-channel-tcp" that adds an environment variable to force operation over TCP.
So try this:
$ git pull
$ git checkout adb-channel-tcp
$ EXPERIMENTAL_ADB_CHANNEL_TCP_PORT=2224 ssh sshelper
Does this fix the problem, compared to:
$ ssh sshelper
If so, that'd be an odd case of data corruption - your dump does not show any obvious signs of it though. It'd probably help to know what Android is seeing on its side - this will be hard to find out with SSHelper, though.

Still no luck.
Starting from scratch on a new macOS 10.12.4 system, I authorized the computer on the Android screen and then tried connecting with and without the change, and with the suggested same port (%p) and a manual tcp:2224.

I'll need to review the code and retrace this tomorrow, but in case you're faster than me, my results are above. I modified the above comment so as to keep only the relevant info but preserve the first just in case. Please see the web page in case it doesn't email the modification.

This actually works fine on the socket when I manually run the commands. The problem seems to lie in ProxyCommand?
This works:
t=`mktemp -d -t adb-channel.XXXXXX`
adb forward --remove-all; adb shell am start -W com.arachnoid.sshelper/.SSHelperActivity; sleep 3; adb forward localfilesystem:${t}/sock tcp:2222;
ssh -v -v -v -oProxyCommand="sh -c 'socat stdio unix:${t}/sock'" localhost
This fails:
t=`mktemp -d -t adb-channel.XXXXXX`
ssh -v -v -v -oProxyCommand="sh -c 'adb forward --remove-all; adb shell am start -W com.arachnoid.sshelper/.SSHelperActivity; sleep 3; adb forward localfilesystem:${t}/sock tcp:2222; socat stdio unix:${t}/sock'" localhost

OK, the problem was with adb shell interfering with stdin. I was able to resolve the issue by using the flag -n, in #13
I did not think it was necessary to branch by operating system, but it would be good to confirm this still works as expected in Linux (and I would be interested to know if it really worked there without this change!).
