To receive updates from the official clamav servers, which outgoing port do you recommend I enable to communicate from my server to the claimAV update server?
Connections use a 'source port' at the client end and a 'destination port' at the server end. These are agreed during the setup of the connection, and last for its life (but there are oddities, like FTP, which may use more than a single pair of ports). Under normal circumstances the servers don't care which source port a client uses, as long as it uses the correct destination port(s) for a connection. The destination port will normally be port 80 for HTTP, and port 443 for HTTPS. Outgoing connections for HTTP generally use an epehemeral port https://en.wikipedia.org/wiki/Ephemeral_port and the network stack software generally deals with all that for you. It's completely transparent to the application using the connection. It's an unusual question, is there a particular reason for posing it? -- 73, Ged. _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
