Lusca-head in production with tproxy!

I've deployed Lusca head (the very latest head revision) in production for a client who is using a patched FreeBSD-7.2-STABLE to implement full transparency.

I'm using the patches and ipfw config available at http://tproxy.no-ip.org/ .

The latest Lusca fixes some of the method_t related crashes due to some work done last year in Squid-2.HEAD. It seems quite stable now. The bugs only get tickled with invalid requests - so they show up in production but not with local testing. Hm, I need to "extend" my local testing to include generating a wide variety of errors.

Getting back on track, I've also helped another Lusca user deploy full transparency using the TPROXY4 support in the latest Linux kernel (I believe under Debian-unstable?) He helped me iron out some of the bugs which I've just not seen in my local testing. The important ones (method_t in particular) have been fixed; he's been filing Lusca issues in the google code tracker so I don't forget them. Ah, if all users were as helpful. :)

Anyway. Its nice to see Lusca in production. My customer should be turning it on for their entire satellite link (somewhere between 50 and 100mbit I think) in the next couple of days. I believe the other user has enabled it for 5000 odd users. I'll be asking them both for some statistics to publish once the cache has filled and has been tuned.

Stay tuned for example configurations and tutorials covering how this all works. :)
