Adding google repository to Ubuntu or Debian based distros.

Add the following rule to e.g. /etc/apt/sources.list, or if your distro has the /etc/apt/sources.list.d/ directory, add it to a file called google.list in that directory:

# Google software repository
deb http://dl.google.com/linux/deb/ stable non-free main

Once the above entry is added we can run apt as usual.

Running fsck on your server

24-Nov-09

Q. My laptop partition  /dev/sdb1  is showing file system error, how  do i use fsck command to check for file system error and repair the partition.

Solution  is to use   fsck – check and repair a Linux file system or use e2fsck – check a Linux ext2/ext3 file system.

Device              Start       End Blocks      Id                      System
/dev/sdb1      1               2861              2011014+ 6   FAT16

Step 1 – Go to single user mode if needed and then Unmount the partition.

root@laptop:# init 1     [for my laptop there was no need to go to single user mode, as i was able to unmount the partition]

root@laptop:# umount /dev/sdb1

Step 2 – Run Fsck on /dev/sdb1

root@laptop:# fsck -yvf /dev/sdb1

fsck 1.41.4 (27-Jan-2009)
dosfsck 3.0.1 (23 Nov 2008)
dosfsck 3.0.1, 23 Nov 2008, FAT32, LFN
Checking we can access the last sector of the filesystem
Boot sector contents:
System ID “MSDOS5.0″
Media byte 0xf8 (hard disk)
512 bytes per logical sector
32768 bytes per cluster
4 reserved sectors
First FAT starts at byte 2048 (sector 4)
2 FATs, 16 bit entries
125952 bytes per FAT (= 246 sectors)
Root directory starts at byte 253952 (sector 496)
512 root directory entries
Data area starts at byte 270336 (sector 528)
62835 data clusters (2058977280 bytes)

243 hidden sectors
4022029 sectors total
Reclaiming unconnected clusters.
/dev/sdb1: 1050 files, 53941/62835 clusters

You can also user logsave which saves the output of a command in a logfile.

root@laptop:# logsave -asv /var/log/fsck.log fsck -y /dev/sdb1
Log of fsck -y /dev/sdb1

fsck 1.41.4 (27-Jan-2009)
dosfsck 3.0.1, 23 Nov 2008, FAT32, LFN
/dev/sdb1: 1050 files, 53941/62835 clusters

Tue Nov 24 13:25:07 2009

Closing open DNS server. Add the following to your named.conf file.

Add the following, replacing mainIP and secondaryIP with your systems nameservers.

acl "trusted" {
mainIP;secondaryIP;127.0.0.1;
};

Example:

acl "trusted" {

mainIP;secondaryIP;firstserverip;secondserverip;127.0.0.1;

};

Only the trusted IP is allowed for certain functions.

allow-recursion { trusted; };
allow-notify { trusted; };
allow-transfer { trusted; };

Example:

include "/etc/rndc.key";

controls {
inet 127.0.0.1 allow { localhost; } keys { "rndckey"; };
};

acl "trusted" {
ip1;ip2;ip3;ip4;ip5;127.0.0.1;
};

//
// named.conf for Red Hat caching-nameserver
//

options {
directory "/var/named";
allow-recursion { trusted };
allow-notify { trusted };
allow-transfer { trusted };
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
