git gc and bup

To avoid the OOM killer (…) after a git gc call on a bup repository:

$git config –global pack.windowMemory 512m
$git config –global pack.threads 10

backup LVM LV with bup

Bup is a backup software that use git for the storage. Bup import chunks of file to deduplicate large files.

tosh-r630:~/backup$cat /dev/mapper/virtualmachines-sarge | bup split -n virtualmachines-sarges
bloom: adding 1 file (10967 objects).
tosh-r630:~/backup$bup join virtualmachines-sarges > /tmp/sarges.img
tosh-r630:~/backup$file /tmp/sarges.img
/tmp/sarges.img: x86 boot sector; GRand Unified Bootloader, stage1 version 0×3, stage2 address 0×2000, stage2 segment 0×200, GRUB version 0.94; partition 1: ID=0×83, active, starthead 1, startsector 63, 9976302 sectors; partition 2: ID=0×5, starthead 0, startsector 9976365, 498015 sectors, code offset 0×48

Wininetd 0.7

Just a remainder, this is the command line needed to build WinInetd with gcc:

gcc service.c wininetd.c -lws2_32 -lm

OpenSSL1.0.0e+Net::SSLeay on Windows

I managed to get Net::SSLeay to work with the last OpenSSL release. Here just some not for myself.

OpenSSL test-suite build will fail but the .a and the openssl.exe file are ok.

The openssl.exe binary is in apps/ on Windows, not bin. Net::SSleay Makefile.PL file to find the OpenSSL distribution because of that.

How to grab Thunderbird 3.0.4 sources

Commit references commits can be found in the release note on the wiki: https://wiki.mozilla.org/Releases/Thunderbird_3.0.4


hg clone -r b8e06312e645 http://hg.mozilla.org/releases/comm-1.9.1 thunderbird
cd thunderbird
echo 'ac_add_options --enable-application=mail' > .mozconfig
echo 'mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/objdir-tb-release' >> .mozconfig
hg clone -r ead1204d8b81 http://hg.mozilla.org/releases/mozilla-1.9.1 mozilla


Install the build dependencies ( https://developer.mozilla.org/En/Simple_Firefox_build ).

Now we can launch the build


make -f client.mk


Debian Vserver cheat Sheet

This is just to keep a trace for myself on how to create a Vserver with Internet connectivity.

Create the network interface
Edit /etc/network/interfaces and add:

auto dummy0
iface dummy0 inet static
address 192.168.50.1
netmask 255.255.255.0


Restart the network

/etc/init.d/networking restart


Turns the NAT on

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

eth0 here is the network interface you use for your network access.

Create the VM

sudo vserver build build -n cyrus2.3 -m debootstrap --netdev dummy0 --interface 192.168.50.2/24 -- -d lenny


Enter the VM

sudo vserver cyrus2.3 start
sudo vserver cyrus2.3 enter

How to query Windows Vista registry with Samba4 regshell

I’d to enable (with lusrmsgr.msc) and use the Administrator account.

thunderbird-2.0.0.23 built by Mozilla and Debian Squeeze

Mozilla still builds against libstdc++5…


/opt/thunderbird-2.0.0.23$ ./thunderbird
./thunderbird-bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory


The solution is very simple. Just use libstdc++5 from Lenny:

http://ftp.fi.debian.org/debian/pool/main/g/gcc-3.3/libstdc++5_3.3.6-18_i386.deb

sudo dpkg -i libstdc++5_3.3.6-18_i386.deb


Nouveau blog !

Après plus d’une année de réflexion, j’ai laissé tomber l’administration de mon propre WordPress et je ne switcherai finalement pas à pyBlosxon que je trouve un peu juste au niveau interactivité.

Donc finalement me voila chez WordPress.com

Je vais de nouveau avoir un outil pour raler de façon efficace !
