For GRE tunneling, how can I specify the parameters for tunneling device, so that I ifup-tunnel will automatically read and start the interface and I don't have to write the below scripts in my start-up file.
Apparently you have to create a /etc/sysconfig/network-scripts/ifcfg-gre2 file with content similar to this one:
ONBOOT=yes DEVICE=gre2 TYPE=GRE MY_INNER_IPADDR=192.168.61.1 MY_OUTER_IPADDR=79.189.10.22 PEER_INNER_IPADDR=192.168.62.1 PEER_OUTER_IPADDR=84.234.113.51
By the way, I never did this before, and had no idea on how to do it, but Google just lead me to the conclusion that this is the way to go in about 5s. First, /etc/sysconfig/network-scripts/ifup-tunnel is a script, so looking into that file I saw that it was using some variables such as PEER_INNER_IPADDR. I looked for that name in Google, and one of the results was this page [http://bart.prokop.name/blog/unleash/linux/centos.html], which starts in Polish (?) but then continues in English with explanation enough on how to do that.
Although using the mailing lists is "easy" and very effective, one of the advantages of Linux is that you can always "look inside" it, and as many components are scripts, looking inside is actually quite easy. Next time, please try to do your own poking and research before going the mailing list route.
HTH, Filipe
