Rogrs is my cable ISP provider. They supply the model and give out a DHCP address. Yes I know out things like DynDNS. They also perform scans and if they find a listening SMTP or http server they send a notice asking you to remove it OR ELSE YOUR SERVICE WILL BE TERMINATED ! ! !
The Rogers host name is static, so long as you don't change hardware.
Mine has changed with a period of around 6 months over the last few years. YMMV.
So, I use an alias on the DNS server I use. The only ports I have open are ssh & imaps. Also, I don't know how much scanning they do on my tunneled IPv6 addresses (I've only got 2^72 of them).
Several years ago, someone from Rogers mentioned they generally don't go after people with servers, but retain the right to, for those who run popular public servers.
I have had such notice and know a few others who have. Mine was for SMTP, other were for http, none of who said they had much traffic. I once worked in another part of Rogers and did ask they said yes it was policy and yes they did scan. Until about 5 years ago I ran a port watcher since my NATing f/w was a Linux box (its now a NETGEAR switch) and I saw a scan every five or six weeks. Maybe things have changed since then. I don't know anything about the IPV6 situation. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
