[CNT-20080910.71828]: [sonatype03] - Apache Availibility
Team,
We've received alerts for Apache on Sonatype03 due to max clients being reached. I've bumped the max clients up to 512 to return the site to a usable state, which seems to be working out so far. Unfortunately, unlike what we normally see, there isn't any one IP doing that much damage. It instead appears to just be a barrage of different IPs all holding 30 or less connections. Please let us know if you'd like any further action taken at this time.
Thanks,
-Mark

Hi repo mainteners & PMCs,
What do you think about this proposal ?
I think it could be a good solution to keep the quality of service of the
central repo ?

Arnaud:
I was able to find the following:
http://dominia.org/djao/limitipconn2.html
This *might* suit your needs. From the readme, it looks like it can be defined on the server wide, and vhost levels. In the vhost you can define maximum ip connections within location tags, so that would allow fine grained control over which locations you wanted to limit.
Also, when an ip is maxing out the limit you define, it will force apache to return a 503 response code. You could then define your 503 ErrorDocument to be whatever you like. Even customize it to look like the site itself, but of course display an error message saying that you've exceeded your connection limit. Please look this over and let me know if you thing this will meet your needs.
Thanks,
-Chris

Hi guys,
Couldn't we reduce the maximum number of connections from an IP to 20 or
10 ?
Actually maven doesn't support // downloads.
It can be a problem for corporate environment if a lot of users are
downloding artifacts at the same time, they will have the same IP from the
central point of view.
But we could alert them to install a repository proxy. Could we have a
custom error message when an IP exceed its quotas ? What is the HTTP error
code sent to the user ?
