Our /etc/services currently contains these irc ports: irc 194/tcp # Internet Relay Chat Protocol irc 194/udp ircs 994/tcp # irc protocol over TLS/SSL ircs 994/udp ircd 6667/tcp # Internet Relay Chat ircd 6667/udp While 994 is the original irc/tls port most servers use 6697 (bc it's a non-privileged port) and this is now also official via RFC 7194. It has an explicit name and description that should be used: ircs-u 6697/tcp Internet Relay Chat via TLS/SSL See https://tools.ietf.org/html/rfc7194 We should add that to baselayout's /etc/services.
This will be included in baselayout-2.3. The commit id is db65c12.
