Named pipe stops working after a while the system is on #20

maicol07 · 2022-05-24T17:49:49Z

It seems that named pipe stops working after a while the system is on:

PS C:\Users\Maicol> ssh-add -l
Error connecting to agent: No such file or directory
PS C:\Users\Maicol> Get-ChildItem \\.\pipe\|findstr open
------        01/01/1601     01:00              1 openssh-ssh-agent

WSL:

  ~ ❯ ssh-add -l                                                                                              19:43:23
error fetching identities: communication with agent failed

However, Git bash works:

$ ssh-add -l
3072 SHA256:xInBcA48YT6jmmOEWQrXtC+xw+c6V2V2cVgAWT6K9hg id_rsa (RSA)
256 SHA256:ZgvmgA5CNIpEbTZWepclAdXC9fVBFsB1kvmM14Egjm8 id_ed25519 (ED25519)

I've currently tested the named pipe mode and the 1password proxy mode and the two modes are affected.
Do you have any clue?
Thanks

There may be something wrong with the omni-socat process.
When does this occur?
Does it always result in an error?

Create a debug log output mode to check the status.

masahide · 2022-05-27T04:44:48Z

Please ps the socat process startup in WSL.

https://github.com/masahide/OmniSSHAgent/releases/tag/0.3.1

Added debug log output mode to omni-socat.
Debug mode is enabled by doing the following.
Logs are output to /mnt/c/User/<user_name>/omni-socat.log.

In WSL console, do the following

# kill socat prosess
killall socat 
#　remove old omni-socat.exe
rm ~/omni-socat/omni-socat.exe

Rewrite ~/omni-socat/ubuntu-bash.setup.sh

(setsid socat UNIX-LISTEN:$SSH_AUTH_SOCK,fork EXEC:"$OMNISOCATCMD",nofork &) >/dev/null 2>&1

to

(setsid socat UNIX-LISTEN:$SSH_AUTH_SOCK,fork EXEC:"$OMNISOCATCMD -debug",nofork &) >/dev/null 2>&1

Restart WSL console.

# Try ssh-agent communication
ssh-add -l
# cat logfile
cat  /mnt/c/User/<user_name>/omni-socat.log

When does this occur?

There isn't a specific time when this occurs

Does it always result in an error?

Yes, the error of the OP

Please ps the socat process startup in WSL.

It seems that /usr/bin/socat and $HOME/omni-socat/omni-socat.exe are not communicating.

Check $SSH_AUTH_SOCK

$ echo $SSH_AUTH_SOCK
/home/masahide/.ssh/agent.sock

Check if omni-socat.exe is executable from WSL.

$ ~/omni-socat/omni-socat.exe -h
Usage of omni-socat.exe:

Manually start socat and check operation

# Kill already activated socat
killall socat

socat UNIX-LISTEN:$HOME/.ssh/agent.sock,fork EXEC:"$HOME/omni-socat/omni-socat.exe -debug"

Start another console to check.

I think I'm seeing the same issue:

What's strange is it runs outside of socat:

It was working on Friday (May 27) but broke between then and today (May 31).

I tried:

building omni-socat from source
switching to npiperelay
switching omni-socat.exe to windows 8 compatability mode

None of those worked

Rebooted my laptop, and it's back to working again 🤷

masahide · 2022-06-01T02:26:53Z

Thank you for your report.
It seems that there is some kind of problem with the linkage between socat and omni-socat.
However, I think the internal implementation of npiperelay is almost the same, so if npiperelay doesn't work either, there may be a problem elsewhere.
I will also investigate.(I haven't been able to reproduce the problem yet, but from there...)

Thank you very much.

Do you get help by running /home/maicol07/omni-socat/omni-socat.exe -h?
Also
sha1sum /home/maicol07/omni-socat/omni-socat.exe
and
ls -la $SSH_AUTH_SOCK
please.

maicol07 · 2022-06-03T07:02:02Z

Rebooted and works... next time!

masahide · 2022-06-07T11:10:37Z

Thanks.
From the information you gave us, it looks like the omni-socat.exe is fine and the socat process is causing the problem.

It may be a problem with the combination of socat and WSL2.
microsoft/WSL#7560

I'll look into it some more, but if there's nothing I can do about it. I think I can solve this problem by creating something like socat myself. Please give me some time.

maicol07 · 2022-06-10T14:20:33Z

New issue today, but I don't know if it's related:

Useful detail (maybe): restarting 1password when this happens fixes the issue

masahide · 2022-06-25T09:47:04Z

Useful detail (maybe): restarting 1password when this happens fixes the issue

When 1password was restarted, did socat recover without KILL?

maicol07 · 2022-06-25T09:48:43Z

Yes, I only restart 1Password. Other things and services are untouched

masahide · 2022-06-26T08:10:30Z

It may be a glitch on 1password's part.
If you get the error again, could you try ssh-add.exe in windows.

Could you try ssh-add -L?

C:\Windows\System32\OpenSSH\ssh-add.exe -L
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIChI8AXMLP3pp1/9++H9Ebh3BiqMGJMIhc5f4Pxtk+By id_ed25519 masahide 20220322

If you get a key list error with ssh-add.exe, it may be a bug on 1password's side.

maicol07 · 2022-06-27T12:29:38Z

@masahide windows ssh-add never worked for me (in the PC I'm currrently using. On another PC works):

PS C:\Users\Maicol> ssh-add -L
Error connecting to agent: No such file or directory
PS C:\Users\Maicol> ssh-add.exe -L
Error connecting to agent: No such file or directory

I'm not sure whether restarting 1Password fixes the original test (I will try that when I get it), but it fixes this one: #20 (comment)

masahide · 2022-06-27T23:59:11Z

If C:\WindowsSystem32\OpenSSH\ssh-add.exe outputs "Error connecting to agent: No such file or directory", the 1password ssh agent is not functioning properly.

I've debugged a bit and it seems Omni overwrites the pipe used by Microsoft OpenSSH:

I've checked in env variables and there was a manually added SSH_AUTH_SOCK variable that was causing this issue.

I'll keep you updated if I have the previous issues

masahide · 2022-06-28T14:01:46Z

Sorry, I'm sorry, I'm not sure if you are using Cygwin/MSYS2/Git for windows.
In that case, ssh-add.exe may not work because you have rewritten the environment variable "SSH_AUTH_SOCK" as you indicated.

maicol07 · 2022-06-28T14:17:50Z

No, I'm not using Cygwin and the others.

I'm only using WSL2 and rarely Powershell

ddrown · 2023-04-08T01:33:25Z

I've been using this every day since I added my comments, and it's been stable ever since then. I guess something changed, but I don't know what.

masahide · 2023-04-08T01:49:00Z

Thank you for the information.
However, the cause of this particular problem is still unknown and no particular measures have been taken. Maybe there is some underlying timing or combination problem. I will continue to wait for the report.
