Update (fsaua) doesn't work on my Linux servers

Hi,

On my Linux Ubuntu 14.04.5 LTS (yes, it's old and no longer maintained, but it is the system required by one of our provider - shame on these guys!).


There are information about versions:


 - Ubuntu 14.04.5 LTS

 - F-Secure Linux Security 11.10 build 68

 - F-Secure Firewall Daemon 11.10 build 68

 - F-Secure Integrity Checker 11.10 build 68

 - F-Secure On-Access Scanning Daemon 11.10 build 68

 - F-Secure Management Agent 4.75 build 79


I'm using PSB managed installation. I follow this installation procedure:


8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-

sudo bash fsls-11.10.68 --auto psb fspsbs=http://psb1-smi-bw.sp.f-secure.com/ keycode=XXXX-XXXX-XXXX-XXXX-XXXX

/opt/f-secure/fsav/sbin/fschooser

# (  “f”<enter> <enter> )

sudo /etc/init.d/fsma restart

8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-


Note: on the following trace, the system is up to date because cron job perform regularly a manual update.


8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-

wget http://download.f-secure.com/latest/fsdbupdate9.run

/opt/f-secure/fssp/bin/dbupdate /tmp/fsdbupdate9.run

/etc/init.d/fsma restart

8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-


Communication with PSB is working: PSB says me that the DB is not uptodate, I run manual update, and PSB remove the warning.


fsaua is running:


8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-

gw01:~$ ps auxf | grep fsaua

Using tcpdump, I validate periodic communication between fsaua and F-Secure servers: (I dont join the capture because our licence-key is contained in the excanged base64 data). There is an extract of the communication:

The fsaua logs contain ONLY lines with content similar to the following.


8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-

Mon May 11 07:55:11 2020(2):  Connecting to http://psb1-smi-bw.sp.f-secure.com/ (no BW proxy, no HTTP proxy)...

Mon May 11 07:55:11 2020(2): Update check completed successfully. No updates are available.

8< -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-


My logs are from Apr 12 2020, to May 13 2020. I remove "no update" indication. The remaining logs line doesn't contains any update confirmation.


No update during 30 days, this is not possible. During this 30 days, I count 1265 attemps of update with always the result "No updates are available."


I join at the end of this post:

 - "fsauatool -g" report

 - full listing of /var/opt/f-secure/fsaua directory


Someone has any idea ?

    Hi Thierry

    Check the connectivity status when the issue is reproduced by running the following commands on Terminal:

    ping x-bw.sp.f-secure.com

    nslookup x-bw.sp.f-secure.com

    curl -v http://x-bw.sp.f-secure.com


    Depending on your cluster 'x' denotes:

    EMEA (PSB1)

    America (PSB2)

    APAC (PSB3)

    EMEA2 (PSB4)

    EMEA3 (EUSMI)


    If the connection is working fine (HTTP response code is "200 OK"), then run the database reset with following the instructions below:


    Run the following command in the host installed with F-Secure Linux Security.


    Note: All steps require root privileges.


    # /etc/init.d/fsma stop

    # /etc/init.d/fsaua stop

    # ps - efl | grep fsupdated (check the running status of fsupdated process)

    # kill <PID of remaining fsupdated process> (If there is any remaining one, kill it)

    # rm - rf / var / opt / f - secure / fsaua / data / content / *

    # /etc/init.d/fsaua start

    # /etc/init.d/fsma start


    This will force F-Secure Automatic Update Agent (AUA) to download again all database packages.

    Hi, thanks for the answer. In summary:

    • I'm in France, I use psb1
    • Tests seems ok
    • Stop, delete file and restart were done
    • The fsaua doesn't download anything. The directory /var/opt/f-secure/fsaua/data/content/ remain empty, and it is no longer filled by fsaua.
