So ssh2 is deprecated. If ssh works, that is the one that should work. We kept ssh2 for a few years in case people had issues while we migrated from libssh2 to libssh.
On our new mosh version failing, can you send mosh --verbose
so we can see what may be going on?

Ha! I see what the problem is:
bootstrapMoshServer: Command output: Failed binding to 10.0.0.101:60000
Error binding to IP 10.0.0.101: bind: Address already in use
Failed binding to 0.0.0.0:60000
Error binding to any interface: bind: Address already in use
Network exception: bind: Address already in use
But in the config for the host’s ports I have 60000:61000.
Don’t know why it tries to use 60000 all the time.
I just checked, if I remove the port config and leave it empty, it iterates and does go 60000, 60001, etc.
But when I have that config there it always tries to use 60000.
Seems like a defect?
Thanks!

Seemingly out of the blue, this morning my long-established mosh sessions started terminating, and I have not had much luck re-establishing them. No configuration changes on the remote host, no updates or packages installed. I was working away without issue for 1-2 hours then suddenly this issue started, and has persisted since.
With some manual establishing of LC_ALL I can get ssh to connect through blink with less issue, I can locally mosh (from remote host to remote host), but I cannot mosh TO the remote host from blink on my iPad.

This looks to be the blink local activity. The actual remote connection attempt from this output:

It seems as if something has forgotten/lost the locale. I don’t seem to have much flexibility on the blink.sh side of things, and I’ve done what I can on the remote side to assuage its issues, seemingly to no avail.
I have no issue using mosh or ssh from another system. It just seems local to my blink.sh on my iPad.
Full range of MOSH ports open on the firewall.
And was working fine until today (April 27, 2024) until sometime into the 10AM hour (EDT).
Is there some background updating I am not aware of?
I may try removing and reinstalling the blink.sh app to see if it changes the current situation.

Hi @wedge1020
This seems unrelated to the Issue mentioned here. What version of Blink are you running?
In any case, it looks like what has changed is on your server. Mosh needs to have a UTF-8 locale and it looks like your server is not providing it.
If you try running mosh-server new -s -c 256 -l LANG=en_US.UTF-8
on the server manually over SSH, do you get a valid server output?

Hi @wedge1020
This seems unrelated to the Issue mentioned here. What version of Blink are you running?
Apologies. On scanning the issues I had found some of the symptoms similar, and didn’t want to further pollute the solution space.
Blink: v17.2.2.868 (App Store). Mar 11 2024
In any case, it looks like what has changed is on your server. Mosh needs to have a UTF-8 locale and it looks like your server is not providing it.
Only, I had made no such changes.
When I SSH from blink, it works.
When I MOSH/SSH from my MacBook, it works.
If you try running
mosh-server new -s -c 256 -l LANG=en_US.UTF-8
on the server manually over SSH, do you get a valid server output?
I didn’t get to try this; first thing I did this morning was remove the blink app and reinstall it.
Everything seemed to resolve: I can now MOSH in as I had before.
Perhaps some local app data had gotten corrupted?
Certainly odd, as yes, it would otherwise have suggested something had happened to my en_US.UTF-8 locale on my remote machine, despite being able to demonstrate otherwise.
