postfix-2.9.20110501 SRC RPM With sqlite3 Support

Since postfix-2.9. 20100617, sqlite3 support feature was added. Now, in  postfix-2.9.20110501 rpm source, i’ve included sqlite3 feature after some tweaking on Simon J. Mudd’s postfix source. Adding sqlite3 support howto can be read officially from here:

Before getting any further, i must warn you that i’m not test sqlite feature yet, since i don’t use sqlite as sql storage backend. it was compiled againts sqlite library in my system. but not tested.

rpm source can be obtain here:

Instructions:

After download the source install the source

$ rpm -Uvh  postfix-2.9.20110501.src.rpm

nginx mod_strip module and textarea

I was asking to Evan Miller if his nginx mod_strip module can honour <textarea> tag. i got quick responses from him.
previous mod_strip module eliminates newline characters within <textarea> list contents. here’s examples with latest mod_strip. I’ve tested it using postfixadmin.

configuration:

server {
         listen		xxx.xxx.xxx.xxx:80;
         server_name	www.example.com;
         strip		on;
         access_log	/var/log/nginx/www.example.com-access.log  main;

         location  / {
             proxy_set_header Host $host;
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header X-Forwarded-Host $host;
             proxy_set_header X-Forwarded-Server $host;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_pass http://127.0.0.1:80;
         }

Nginx + Vlc Streaming Cheap Webcam

webcam streaming

I was experimenting with cheap webcam, vlc on my windows xp workstation. Playing directly using vlc, performance was adequate. but when it came accross network/WAN, delay started increasing between 4-5 seconds(video/audio). i suspect, transcoding are behind these streaming lag. i don’t know what is the best tuning. but here’s the final setting.

start /high vlc.exe --logo-file avatar.png dshow:// :dshow-vdev="VideoCAM Eye" :dshow-adev="SigmaTel Audio" :dshow-caching="0" :sout=#transcode{vcodec=h264{keyint=15,vbv-maxrate=160,vbv-bufsize=160},acodec=mp3,deinterlace,samplerate=44100,sfilter=logo}:std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:8088/stream.flv,sdp=sap://,name="Webcam 3G"} --ttl 12

Build Nginx RPM With ngx_cache_purge module

I’m not going have much words to say, here we go..

first download nginx source rpm from this excellent contributor/packager and install the source

$ wget http://centos.alt.ru/pub/nginx/0.9/RHEL/SRPMS/nginx-0.9.5-1.el5.src.rpm
$ rpm -Uvh  nginx-0.9.5-1.el5.src.rpm

Change to /path/rpm/SOURCE and download ngx_cache_purge

$ cd `rpm --eval '%{_sourcedir}'`
$ wget http://labs.frickle.com/files/ngx_cache_purge-1.2.tar.gz

Now we need to modified nginx.spec a bit, so it will include ngx_cache_purge module when compiled

$ cd `rpm --eval '%{_specdir}' `
$ vi nginx.spec

Add ngx_cache_source-1.2.tar.gz module to source list as Source20

Source11:       nginx_mod_h264_streaming-2.2.7.tar.gz
Source20:       ngx_cache_purge-1.2.tar.gz

In %prep section add this line %setup -T -D -a 20

%setup -T -D -a 11
%setup -T -D -a 20
%setup -T -D -a 21

In %build section add this line –add-module=%{_builddir}/nginx-%{version}/ngx_cache_purge-1.2 \

...
    --add-module=%{_builddir}/nginx-%{version}/nginx_upload_module-2.2.0 \
    --add-module=%{_builddir}/nginx-%{version}/ngx_cache_purge-1.2 \
    --add-module=%{_builddir}/nginx-%{version}/nginx_mod_h264_streaming-2.2.7
...
