Re: Lots of spam on this list

There is not much that can be done about that as it is seen as legitimate email. Well mostly anyway. I've added some filters for some obvious ones. It's really painful that someone is subscribing us to a number of newsletters and such. The filters catch pretty well, 99 emails on the elapsed week. I tried to forward all those which leaked to this list via an anti-spam appliance just to see how many could get caught, and none of them was tagged as spam this time, while this anti-spam already catches a few false positives from time to time... We'll monitor the situation and see if we can improve without degrading the usability of the list. Willy

Basically I want zero FP, I don't want users to have to resubscribe and I don't want to filter based on subscriptions. However I have another idea that I'll have to experiment with. We have two barracudas in front of haproxy.com and I'll have to see with the guys who manage them if we can pass all @formilux.org traffic overthere and just have them add a [SPAM] tag to the subject so that each individual user decides to delete or not. I also need to check with a few other people using formilux.org if they agree with their e-mails passing through such a box. Thanks, Willy

tcp-check not checking
Hi, I just configured the load-balacing for systems that are yet to be installed yet according to the tcp-check of haproxy these systems are all available. This is the backend config I'm using right now: backend back-api bind-process 1 option tcp-check mode http balance roundrobin stick-table type ip size 100k expire 20m stick on src server web1 10.2.0.224:80 check server web2 10.2.0.254:80 check server web3 10.2.0.223:80 check server web4 10.2.0.253:80 check server web5 10.2.0.222:80 check server web6 10.2.0.252:80 check When I look at the stats page all servers are marked active and LastChk says Layer7 check passed: (tcp-check) even though none of the servers are online yet. Does anyone know the reason for this? Regards, Dennis
Re: tcp-check not checking
Hi Dennis, option tcp-check that requires more send/expect options to actually perform L7 checks. For a simple L4 check remove the line completely or add : tcp-check connect You might also want to look at option httpchk. Which is more friendly for basic http checks.

Hi, indeed after removing the option tcp-check line the checks now work as expected. Thanks for the pointer.

Re: change the size of a stick-table at run time
Please don't forget to Cc the ML, unless there are private information in your email. Oh, sorry. I missed that. 'peer' section is also used to synchronize data between HAProxy processes, when HAProxy is reloaded. You should use it. create a 'peer' section and don't forget to use the 'peers' directive on the stick-table definition. Thanks! That was exactly what I needed. -Tobi
