creating a cvs repository on an ISP webspace

[John]

Hi,
I am new to setting up a cvs server and not well versed in networking in
general. I would like to setup a cvs repository on the webspace I have on my
ISP. I don't have execute rights on the webspace folder. Here are a couple
questions to start me out:

1) Is it possible to set up a cvs repository on the webspace offered by
conventional ISPs?
2) Does cvs.exe have to run on the machine with the repository?
3) I tried running
cvs -d :pserver:<ISP ip address>:<port>:/<my folder> init
I got the following error:
cvs [init aborted]: connect to <ISP ip address>:2401 failed: Connection
timed out
also tried:
cvs -d :pserver:<ISP domain name>:<port>:/<my folder> init
and got the following error:
cvs [init aborted]: connect to <ISP domain name>:2401 failed: Connection
timed out
which seems to mean that pserver was able to resolve the ip address from the
domain name but didn't change to <port> which is not 2401.

Thanks for any advice,
John
