Get the domain NS glue record using dig

First check the root servers for the tld (in my case .net)
BASH-Code:
1
2
3
4
5

10
11

$ dig net NS +short
e.gtld-servers.net.
c.gtld-servers.net.
h.gtld-servers.net.
j.gtld-servers.net.
l.gtld-servers.net.
i.gtld-servers.net.
d.gtld-servers.net.
g.gtld-servers.net.
a.gtld-servers.net.
m.gtld-servers.net.
f.gtld-servers.net.
k.gtld-servers.net.
b.gtld-servers.net.

Pick one and send a query to the rootserver:
BASH-Code:
1
2
3
4

$ dig @b.gtld-servers.net tipido.net NS
;; ADDITIONAL SECTION:
ns1.tipido.com.		172800	IN	A	46.4.71.122
ns2.tipido.com.		172800	IN	A	84.23.79.58

The ADDITIONAL SECTION contains the glue records

Squid: http_port to outgoing_address

2011-08-15 by xpheas
My Squid server has 4 public IP-adresses and 4 private adresses. Each private address should map to a public one.

First add the private ones:
BASH-Code:
1
2
3
4

http_port 192.168.1.1:3128
http_port 192.168.1.2:3128
http_port 192.168.1.3:3128
http_port 192.168.1.4:3128

Now define the ACL's
BASH-Code:
1
2
3
4

acl src_01 myip 192.168.1.1
acl src_02 myip 192.168.1.2
acl src_03 myip 192.168.1.3
acl src_04 myip 192.168.1.4

And finally define the outgoing addresses:
BASH-Code:
1
2
3
4

tcp_outgoing_address 93.xx.xx.52 src_01
tcp_outgoing_address 93.xx.xx.53 src_02
tcp_outgoing_address 93.xx.xx.54 src_03
tcp_outgoing_address 93.xx.xx.55 src_04
