AMS Laptop Antivirus definitions update procedure

1) Open Ku-Fwd as usual way
2) run the script 'kufwd-update-clamav-db'
3) Stop Ku-Fwd
3) Wait until the next anitivirus scan (it's performed at 04:00, 12:00, 20:00 GMT every day).
4) Wait another 40 mins to complete the scan
5) Perform another file downlink to check the new definitions date.
--- check it with Mike: 6) Give a call to OC on his/her loop and let him/her know that the ams laptop antivirus was updated to 'date you
got'.  NOTE: No more DSR - No need to "Ask OC to post it in DSR (Daily summary report)."

12. Rename *.cvd to *.cvd.curr on pcpoc30

clamav update and scan

0. manually install clamav on laptop2 with rmp, yumdownload, scp virus database to laptop, wait for cron to run

(see the kufwd-update-clamav-db script as an example:

1. laptop2

[ams@amslaptop ~]$ cat /etc/cron.d/clamav-cron
0 4,12,20 * * * root bash /home/ams/eAss/scripts/
#10 14 * * * root bash /home/ams/eAss/scripts/

2. POCC console

[data@pcpoc00: ~ ] head scripts/

# Download and update <a href=";nowysiwyg=0" rel="nofollow" title="this topic does not yet exist; you can create it."> ClamAV </a> DB on the laptop

KUFS='./' # <a href=";nowysiwyg=0" rel="nofollow" title="this topic does not yet exist; you can create it."> KuFwd </a> fucntions
DLS='./' # <a href=";nowysiwyg=0" rel="nofollow" title="this topic does not yet exist; you can create it."> ClamAV </a> DB download script

DESTLT=freshclam/ # destination directory on the laptop

3. check the script runnig on laptop2:

[root@amslaptop eAss]# cat /home/ams/eAss/scripts/

Django + python scripts
