Re: why does the subversion.tigris.org website block my IP?

I wasn't sure if I should copy this reply to the list or not. But since
I cannot access the website, and the problem appears to be on the server
and not on the client side, I thought I will copy the list, just in case
a kind soul that administers the subversion website can get my IP
unlocked, if that is indeed what is wrong.

Thanks Paul for your suggestions,

Are you in control, or have access to the firewall info on the
subversion webserver?

I am in full control of the firewall. I have not setup such a filter.
Also it used to work fine in the past. The only thing I could think of
is ident daemon responses, and I have tried it both ways with the identd
 working or with ident repsonses suppressed, it appears to make no

Not sure what protocol or program uses port 3690. Is that a port that is
relevant to being able to browse the subversion website? Or is it an
example of the sort fo things that can be wrong at sites? With it being
higher than port number 1024, I am not sure what you mean here, could
you please explain? Thanks.

No, mine does not.

The thing is, if I set up any other proxy from somewhere on the
internet, then browsing subversion site works fine. So it isn't a port
that is being blocked. It genuinely looks as if the
subversion.tigris.org webserver doesn't like my IP. Maybe there is an
abuser near my IP number and they blocked a whole block.

Thanks for your suggestions,

PPS: As before I am lurking as BigBear on the #svn irc at
irc://freenode.net/svn in case some admin of the website wants to do
real-time tests and logging.

Thanks for any help with this. If there is an email address of a person
that I should direct this email to, and then, if appropriate, only send
a summary with a description of the resolution to the list, please let
me know who that individual is. Thanks.
