Hi all
I have a perfectly functioning ipv4 based eos for ALICE running aquamarine.
I am now trying to get another dual stacked eos with citrine and centos7 up.
I have reinstalled from scratch multiple times and never seem to be able to get it to respond to ipv4, ipv6 it does.
Even when I disabled ipv6 (boot with ipv6.disable=1), it would then start with a zeromq error, but could have been a carry over from previous installs.
I did suspect my ipv6 config was messing with things, but now I know I have a properly setup with dns working properly for ipv6, yet it still refuses to listen on ipv4. sshd and postfix happily connect to ipv4 and ipv6.
I did additionally bring up an apache server as a test and it happily served pages on both 4 and 6.
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2532/master

tcp6 0 0 :::1100 :::* LISTEN 27692/xrootd
tcp6 0 0 :::22 :::* LISTEN 1551/sshd
I do have a private and a public ipv4 (seperate interfaces) and the ipv6 public interface is the same interface as the private ipv4.
This happens on the mgm and fst (one of each for the current setup).
Insights or pointers would be greatly appreciated.
Thanks
Sean
