I am shopping for a cheap VPS and have found 1and1.com, which seems to suit my needs (server uptime, and English speaking support staff not a necessity). Before I jump in, I have a few questions regarding hosting companies and their expectations of a VPS customer.
I plan on running the following services on this vm running FC6 (os noted from their webpage)
- bind9 : serve up external DNS requests (tcp and udp 53).
- postfix : redundant MTA to act as a failover for an MX pool. Requires inbound on tcp port 25, and tcp port 465 (plain text, and SSL based delivery)
- apache : small web server , serving up static html (tcp inbound 80/443)
- ssh : remote console access (tcp 22)
Poking through this form has pointed to numerous threads where customers must contact their support staff, requesting the opening of non-standard ports etc.. Which raises the following questions :
Do VPS providers, filter inbound/outbound traffic? Or will the IP address assigned to my VPS allow for unrestricted in/out bound connections to the WAN?
Am I limited in what software i can install on my system?
My assumption is that, this VM is my new playground with no network or process related restrictions ?
