    Hi I have an ongoing problem from few hours. My server appears to be performing a portscan toward 'random' ip addresses and udp ports. The process that is sending those packets is Asterisk which was already at version 16.29 and I've upgraded it to the last version, 16.30 but the problem persists. I can't provide ssh access to the server but I can provide whatever packets captures you prefer. I'd like to know the source of the problem, if it's some virus in the office of the client or some external attack. Max 100 euros.
