Hi,
let us assume you want to edit a binary file /tmp/binfile and you want to replace all strings matches to “sda” by “hda”.
gnu sed can edit bin files by the \xnn hex notation. The option –in-place changes the original file and makes a backup copy with a file extension .org
michael@devdeb ~# sed -e 's/\x73\x64\x61/\x68\x64\x61/g' /tmp/binfile --in-place=.org
Hi,
let us assume you want to determine which driver is behind a device. For example disk /dev/sdc
By udev. Query the device /dev/sdc by udevadm. Scroll down to the section for the pci device
root@devdeb ~# udevadm info -a -n /dev/sdc
.....
looking at parent device '/devices/pci0000:00/0000:00:10.0':
KERNELS=="0000:00:10.0"
SUBSYSTEMS=="pci"
DRIVERS=="mptspi"
.....
or (the native way) by sysfs
root@devdeb ~# cd /sys/block/sdc root@devdeb ~# cd -P /sys/block/sdc/device /sys/devices/pci0000:00/0000:00:10.0/host2/target2:0:1/2:0:1:0
Go to the pci device
root@devdeb ~# cd /sys/devices/pci0000:00/0000:00:10.0 root@devdeb ~# ls -l driver lrwxrwxrwx 1 root root 0 Dec 22 09:14 driver -> ../../../bus/pci/drivers/mptspi

Hi,
I’m on debian testing and cloning from a git repository fails with error: “gnutls_handshake() failed: Public key signature verification has failed” occured.
git is linked against the libcurl3-gnutls library. Newer versions have a bug when using git over a https proxy.

Hi,
your linux box is connected to an ethernet switch where vlan tagging is configured (trunc) and you want to configure your network manually by ifconfig?
Load the module for tagged vlans 802.1q.

Hi,
proxytunnel offers the ability to open bind a tcp port to localhost and tunnels all traffic through a http proxy to a specific target system.
