Listening on ipv6 only?
Running Zimbra 7.1.0 on ubuntu 8.04 x64
Running SSL IMAP on 993, SSL SMTP on 465.
When doing netstat -tulpn|grep 993 I'm getting:
tcp6 0 0 :::993 :::* LISTEN 7455/java
Does this mean that Zimbra listens on ip6 993 only? How can it be? Intended or a bug?
I don't even have IPv6 address assigned to any interface.
I am having a similar issue with Ubuntu 10.04 & an upgrade from 7.0.1 to 7.1.1.
After the upgrade, zimba only listens on IPv6:
There is one difference, my VPS does have an IPv6 address. That address is not actively in use but I would like to have it enabled for future use..
sudo netstat -anltp | grep :443
tcp6 0 0 :::443 :::* LISTEN 5571/java
Is there a way in which I can enable IPv4 and IPv6?
