First Apache site

v6 apache… Well, it was almost as easy as restart… I added the quad A record for, and it resolved as expected…. netstat -na showed

0[vinyl4]# netstat -na | grep LISTEN | grep 80
tcp46      0      0  *.80                   *.*                    LISTEN

But instead it went to the default webserver… Oh, of course

 NameVirtualHost 2607:f3e0:0:1::17:80

I have been running a few servers for outbound connections. smarthost1 and smarthost2 are both IPv6 aware and are even sending out mail to a few domains that run dual stack by default

0(smarthost1)% grep IPv6 /var/log/maillog | grep "stat=Sent" | wc
      16     303    3961
0(smarthost1)% grep IPv6 /var/log/maillog | grep "stat=Sent" | awk -F"=" '{printf "%s\n",$7}' | sort | uniq [IPv6:2002:cb62:54cd::1], dsn [IPv6:2001:6b0:e:2018::156], dsn [IPv6:2001:9c0:1:1001::35], dsn [IPv6:2001:4f8:fff6::34], dsn [IPv6:2001:9c0:1:1002::82], dsn [IPv6:2001:470:1f04:815::2], dsn [IPv6:2001:470:1c:3c0::2], dsn [IPv6:2607:f010:3fe:102:101c:23ff:febf:cfa7], dsn

hahaha… not even 0.01% of outbound mail yet!!!

Bizarrely enough, I do see some inbound spam attempts (probably from bots) on offsite. For most of my domains, I make offsite the last in MX line. It seems some spam box think they have better luck bypassing spam filters by going to the last MX record. offsite just rejects the connection without an RST so it takes a nice long time to timeout.

I will have to tart up this blog and perhaps put some dancing turtles on ala… Perhaps an animated Orville.

Hello world!

So, why the blog ?  Well, I have been working on understanding IPv6 in my network and for customers and thought I should be capturing along the way what I have been learning.  So why not in blog format.
