Cannot log into Linux console

Cannot log into Linux console

Running latest OS6.10.1

I want to log into Linux console to troubleshoot log files. Connected monitor to HDMI out. Connected keyboard to rear  USB port.

Enabled SSH in GUI.

I get the login prompt. I enter username (same as web login). I enter password. (Same as web login.)

Screen flashes a message (cannot read it). and returns to the Login prompt.

If I try entering the incorrect password, I get a msg. Incorrect password, so I know I am using the correct password.

 

Any suggestions?

Re: Cannot log into Linux console

thanks. Now that I am in, I need to access my logs. i cannot download them using the UI. sorry but i do not know Linux.

I think my volume might be filling or maybe errors. Nothng shows in the UI logs.

Did you download the log zip file from the log page in the admin web ui?  If not, then start there.

 

You'll need to use journalctl to access the logs.  There's a lot of stuff there, so you might find it easier to search for specific stuff

# journalctl --no-pager | grep -i 'search string'

For example you can use 'btrfs' as the search string to look for file system errors.

 

Google on "journalctl" to find more options.

Why are you thinking that?  Can you give us more info on the symptoms you are seeing?

I already tried to download the log from the UI. It just times Out. I tried multiple ways multiple browsers. Nothing works. My only concern was that my system would hang every seven or eight days when the virus checking was running. I have since turned off virus checking and system is running fine. Someone suggested I use the Linux interface to check the logs in detail. The search in the journal did not show any records

Re: Cannot log into Linux console

What apps do you have installed (if any)?

Have you checked to see if the OS system is full?

 

You can just run journalctl -r and page until you see something interesting I guess.  The -r option reverses the sort order (so the newest entries appear first).

Just a VPN app but it is disabled. I am not sure how to check if filesystem is full. The UI shows all is well. Not sure about the Linux commands. I did not see anything interesting in the journalctl.

# cd //
# df . -h
# btrfs fi df .

You can post the results here.  The btrfs output can be a bit confusing to interpret.

me too.

 

One option is to re-enable the antivirus, and see if the bad behavior resumes.

 

Do you need AV on the NAS?  Personally I keep it off (since I have AV software on all the PCs).
