Re: [squid-users] Reverse Proxy

Hi Amos,

One thing I forgot to mentioned

/etc/hosts has this entry
10.200.22.12 mail.airarabia.ae

Output of " host mail.airarabia.ae " from dns is ->
mail.airarabia.ae has address 10.200.9.20

User (browser) reads the host file from individual PCs
cat /etc/hosts | grep "mail.airarabia.ae"
10.200.22.49 mail.airarabia.ae

10.200.22.49 <- squid proxy ip
10.200.22.12 <- OWA ip

Please find the answers below.

changed it to ->
https_port 10.200.22.49:443 defaultsite=mail.airarabia.ae \
cert=/etc/squid/keys/cert.pem key=/etc/squid/keys/key.pem

use this command to generate the ssl certificate

openssl req -x509 -days 365 -newkey rsa:1024 -keyout key.pem -nodes
\-out cert.pem

Actually I forgot to mention it here
It is specified in squid.conf
