  • Route RPKI validation April 1st, 2022
    RPKI is a security framework by which network owners can validate and secure the critical route updates or Border Gateway Protocol (BGP) announcements between public Internet networks. BGP is essentially the central nervous system of the Internet and one of its fundamental building blocks. The main function of BGP is to facilitate efficient routing between Autonomous Systems (AS), by building and maintaining the Internet routing table. The Internet routing table is effectively the navigation system of the Internet and without it, traffic would be unable to flow between its constituent networks. Unfortunately, routing equipment alone cannot distinguish between legitimate and malicious routing announcements,...
  • RIPE – Atlas Anchor February 17th, 2022
    We have become an even more integral part of the RIPE Atlas project by hosting an anchor, a device that allows for latency analysis of traffic between autonomous systems.https://atlas.ripe.net/probes/7073/RIPE Atlas anchors play an integral role in the RIPE Atlas network by acting both as enhanced RIPE Atlas probes with more measurement capacity, as well as regional measurement targets within the greater RIPE Atlas network. Anchors are able to perform many more measurements than a regular RIPE Atlas probe, and the large amount of data they collect is made available to everyone. In addition, anchors act as powerful targets that can...
  • MANRS June 20th, 2020
    GOLINE firmly believes in initiatives to protect networks, improve security and resilience of the global routing system. Therefore we decided to support the MANRS project and join as participants.Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, that provides crucial fixes to reduce the most common routing threats. MANRS offers specific actions via four programs for Network Operators, Internet Exchange Points, CDN and Cloud Providers, and Equipment Vendors. Requirements for Participation Please read the full MANRS Actions document before applying. You can become a participant if you meet these requirements: You (or your company) support...

Sophos UTM problems with rrdcached

Paolo Caparrelli Sophos 22 June 2022

 

Finally, the error went away after the db re-initializing. 

What I did was

1) issued rm /var/log/reporting/rrd/*
2) issued /etc/init.d/syslogng restart
3) issued /etc/init.d/rrdcache restart

… see another error about wrong time ("illegal attempt to update using time…")

4) issued /etc/init.d/postgresql92 rebuild
5) issued /etc/init.d/syslogng restart
6) issued /etc/init.d/rrdcache restart
… no more errors 🙂

Nice side effect:

Some users told me yesterday, that while the rrdcached problem occurs, they had some "Proxy does not respond" errors within their browsers while surfing the web. 
I've seen this in my browser too but couldnt reproduce it. The proxy error came at random and went away after pressing the "reload" button.

Could this be a performance Problem on the UTM due to the rrdcached error? 

I mean, I had a fallback log size growth of 6-7 GB/day and I could imagine that the UTM 320 had something else to do than deliver data to the internal network Wink

Now, after the rrdcached problem, I havent seen the proxy errors anymore, and the whole UTM is much more responsive (WebAdmin, throughput while surfing the Web, …) .
