Anti-Virus not Updating

[l8ton]

Hello,

My RN212 Antivirus will not update.

Firmware: 6.10.5

Antivirus: Jul 09, 2020

I changed the DNS server to 8.8.8.8. and 8.8.4.4

I saw an earlier post where the problem was solved when an engineer removed files that were blocking the download.

Can  the same be done for my system, or is there something I can do myself?

Thank you!

Solution:

1. ssh to ReadyNAS 

   > Username: root 

   > Password: YourAdminPassword

2. Navigate to the clamav directory.

   > cd /var/lib/clamav

3. Rename daily.cld and mirrors.dat files    

     > mv daily.cld daily_2.cld

     > mv mirrors.dat mirrors_2.dat

The virus definition wouldn't download if the original files were  present

4. Run freshclam

   > freshclam

5. Reboot  ReadyNAS

6. Re-enable AV

Notes:

I don't know if this was necessary, but I disabled AV before before beginning the process.

Prior to renaming thefiles in step 3, running freshclam resulted in a "download failure" error, and suggested that there was an internet connection issue. This was not the case.

I got this warning after running freshclam, however there didn't seem to be a problem when I re-enabed AV: 
WARNING: Clamd was NOT notified: Can't connect to clamd through /var/run/clamav/ clamd.ctl: No such file or directory

Do you have any experience with the linux command line (CLI)?

I've used Putty to issue command line copy and delete instructions files on a UNIX server at work

I tried using putty to ssh to the ReadyNAS ip address , but it closed as soon as i entered my PW.

Should I be using a different ssh tool?

Putty will work, though you can also launch ssh directly from the windows command line.

Were you using root as the username and the NAS admin password?

Ok, I'm making progress. Thanks for the tip! 

I was able to get to the linux command line usin root/AdminPW and am now able to list the / NAS directory structure.
