Welcome to janforman.com you can find here infos about downtime of my servers and other stuff.

Wednesday-Thursday 18. Conference ESRI

Narrator: Dean Angelides (ESRI Inc.) Designing Our Future
(share map services across planet and design with live preview of my service :-)
From 21-22.10.2009 / Wednesday to Thursday in Prague Congress Centre you can watch some map (twice) that I designed :-)
This sample runs on nginx reverse proxy and Arcgis server (Apache Tomcat) by ESRI (in OpenVZ containers) and it covers whole Czech Republic.
Clients are AdobeFLEX (thin) and GiselAE (desktop).
There is a very little server overhead, so one server (nginx reverse proxy/load balancer/fail-over) can be used by thousands of clients.

used OS: modified Gentoo Linux (Gentoo Foundation)
remark: as backend there are two Arcgis servers and balancer can auto-switch to second if first fail.

Of course you can meet me here…

Changes on my servers

There is little changes on orion.janforman.com (imagehosting), where I was completely removed Apache webserver in last days and all work is now on NGINX webserver (big speed improvement, memory consumption drop in idle state to 8MB, faster onfly compression/encryption with support of Camellia-256 TLSv1 and GZip level 6). Also there is completely reinstalled mail server which now don’t run spamassasin but only greylisting solution. PHP on explorer.janforman.com and orion.janforman.com is connected in respawn fastcgi mode.
Domain name servers are switched to ns1.janforman.com and ns2.janforman.com.
Webmail updated and now supports vCard import/export /w telephone, better IMAP folder implementation, mail flags and more cool AJAX stuff.

Servers are now running in Parallels Virtuozzo technology.
All services are authorized/configured by SQL query, so there are no accounts for long time.

There is a new schema in servers section, take a look!
A lot of Russian technology is here … ;-)

…And of Course Total traffic is now approx. 0.7TB/per month
(avg. 5-10Mbit/s, 835-3505/packets per second)

SSL_error_rx_unexpected_change_cipher

:-) so if you see this error, you have problem with openssl 0.9.8g.
This is small bug in client part of openssl and now is often visible in new Firefox 3
Simply disable TLS v1 in your server (SSHv2 too because of better security)

Insert this line into httpd.conf

SSLProtocol all -TLSv1 -SSHv2


That’s it :-D
