Tailscale SSH problem #8

Open jim13x opened 1 month ago

jim13x commented 1 month ago

I was unable to start an SSH session over tailscale, and I could see 'ILLEGAL ROOT LOGIN on '/dev/pts/4' from ' in the logs. I found this post:

ILLEGAL ROOT LOGIN on '/dev/pts/4' from

The following fixed it:

echo 'pts/4 pts/5 pts/6 pts/7' >> /etc/securetty

That's extremely strange.

Apologies for not seeing this until now.

What firmware revision?

jim13x commented 1 month ago

I'm running RM520NGLAAR03A03M4G_01.201.01.201. I had been having disconnect issues with RM520NGLAAR03A02M4GA, so I decided to try the newer firmware to see if that would help. I'm going to reinstall it at the remote location this weekend to see how it goes.

Thanks for supporting such a cool project!

@jim13x what firmware did you end of with and did your disconnects go away?

I went back to RM520NGLAAR01A07M4G and it seems more stable. No more PCIe linkdown errors.

Thank you @jim13x . There is information on https://github.com/iamromulan/quectel-rgmii-configuration-notes/discussions/11#discussioncomment-9806774, explaining that MR5210 isn't recommended anymore due to hardware issues on the board.

I removed tailscale because the simpleadmin and board would seem to freeze and not properly assign an IP address to my laptop (using CAT6 directly plugged in). I only tried the latest RM520NGLAAR03A02M4GA but didn't see any PCIe linkdown errors when running dmesg. I am going to try the new board that is recommended now.

Thanks for the heads up!
