Pablo Posted November 7, 2012 Report Share Posted November 7, 2012 I've noticed for several weeks the following entry, in the snom ONE log: UDP: recvfrom 124.59.84.0:49218 returns EAGAIN It appears to be happening about twice per second, w/several entries to the effect of: Last message repeated 33 times After a WHOis search, it appears to be a China IP address. So, I then added the following entry into the Access List: 0.0.0.0/0.0.0.0; but the same entries as above keep showing up in the log, although the IP address will change throughout the day. Is this something to worry about? Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted November 7, 2012 Report Share Posted November 7, 2012 If you are running the PBX service on a public IP address, you get all kinds of crap. Especially in the past month there was a dramatic increase of attacks on SIP service. That is why it is so important to have a mechanism that automatically blocks this kind of traffic. What is important as well is that you have a password policy on the PBX and that you watch these warning signs on accounts. When users choose trivial passwords like account 40 password 40, your system is risk! Also, make sure that all your trunks have the outbound proxy set, so that the PBX does not assume that such unidentified inbound traffic comes from a trunk.
