07:26.18morsingwethrin: You've fallen off the friendly channel
07:26.37morsingwethrin: I've now confirmed that IPv6 and IPv4 do share ports
07:27.00morsingAnd it's a documented feature :(
07:27.52wethrinNo-one's there anyway. And my screen was full of Mohan's leaving and joining
07:28.20wethrinwhen you say 'share ports', do you mean the services that run on them?
07:29.01murbwethrin: i guess he hasn't discovered sys.net.ipv6.bindv6only yet.
07:29.17morsingIf I open port 80 on IPv6, I can connect-ish via IPv4
07:29.23morsingmurb: Idiot
07:30.00morsinghttp://www.google.com/url?sa=t&source=web&cd=1&ved=0CBkQFjAA&url=http%3A%2F%2Flinux.die.net%2Fman%2F7%2Fipv6&rct=j&q=linux%20ipv6%20shared%20port%20space&ei=bV7bTYONNZG6hAem_9yeDw&usg=AFQjCNFfLgIm9MIFx2kpkjS39m5tBHK2Iw&sig2=9pko3fUJaKIM5Lk9gA3veQ&cad=rja
07:30.03wethrineven if you tell Apache not to listen on port 80 on IPV4?
07:30.07morsingYEs
07:30.26morsingIt doesn't necessarily *work*, but you can connect and nmap will show the port
07:31.51murbmorsing: what does strace -e bind have to say?
07:32.09wethrinI'm guessing that what murb said would mean it'll only bind on IPv6, unless IPv4 is specifically requested?
07:32.22murbwethrin: the default is for that setting to be disabled.
07:32.34wethrinAye
07:32.35murbso once you bind to the v6 port the v4 is taken as well.
07:32.52wethrinand if you enable it, you'll have to specifically bind to v4 too?
07:32.57murbyep
07:33.22wethrinhurrah for magic sysctls, etc.
07:34.37murbbut see ipv6(7)
07:34.44wethrinRight, time to head to work
07:35.18murbwhich of course isn't upto date here.
07:36.35murbthere is also a socket option IPV6_V6ONLY which does the same thing.
07:37.08murb(atleast socat supports it!)
07:37.10morsingmurb: lol :)
07:42.19morsingmurb: You're always a great help :)  Your strace command is pointless and the man page just confirms they share the port space :)  
07:42.56murbmorsing: it isn't pointless as you can see what apache is binding to.
07:43.05morsingWhat, 3 and 4?
07:43.39morsingOn ftp is displays nowt - on squid is shows a list of 3s and 4s
