thanks to http://www.namesys.com/shrink_reiserfs.html and http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/custom-guide/s1-swap-adding.html

well, after my hard drive finished acting weird and made me re-install linux, in my haste to get the job done I somehow managed to overlook swap space (i don't know how) and for some reason the debian installer didn't warn me (every other distro i have used has gone "hold up dude, yer screwing up here")!

anyways, i looked into making the necessary changes on the live install with minimal disruption to the service provided by the server (it's the sole gateway to the internet for all my users) and after I made the changes I thought it would make a really good section for this blog, just in case i need it again.

this will just be a copy and paste exercise from the websites mentioned:

Shrinking reiserfs partition HOW-TO

(live example)

Preliminaries

The reiserfs filesystem has a tool for changing its size. Extending of a reiserfs volume can be done if the fs is mounted as well as for not mounted fs. Fs shrinking is supported only when fs is unmounted.

0. Before any change of the disk partition table

First of all you need to backup partition table into a file. If you make a mistake you can re-create partitions at their initial correct places.

[root@haron root]# fdisk -l -u /dev/hda > hda.table.save
[root@haron root]# cat hda.table.save

Disk /dev/hda: 80.0 GB, 80032038912 bytes
255 heads, 63 sectors/track, 9730 cylinders, total 156312576 sectors
Units = sectors of 1 * 512 = 512 bytes

Device Boot Start End Blocks Id System
Device Boot Start End Blocks Id System
/dev/hda1 * 63 122881184 61440561 83 Linux
/dev/hda2 122881185 151557209 14338012+ 83 Linux
/dev/hda4 151557210 156312449 2377620 82 Linux swap
[root@haron root]#
1. Here we start

[root@haron root]# df -T /mnt/testfs/
Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/hda2 reiserfs 14337568 2143672 12193896 15% /mnt/testfs
[root@haron root]#
2. umount the fs and shrink it by 10G (for dirs like /opt, reboot into recovery mode)

further, -s-10G = "shrink by 10GB (100GB - 10GB = 90GB)" and -s+10G = "grow by 10GB (100GB + 10GB = 110GB)"

[root@haron root]# umount /mnt/testfs/

[root@haron root]# resize_reiserfs -s-10G -f /dev/hda2
resize_reiserfs 3.6.11 (2003 www.namesys.com)

ReiserFS report:
blocksize 4096

free blocks 427114 (3048474)
bitmap block count 30 (110)

Syncing..done

resize_reiserfs: Resizing finished successfully.
3. find the fs new size

The new fs size is in resize_reiserfs final report: it said that block count now is 963063. Another way to determine fs size is to run debugreiserfs(8)
[root@haron root]# debugreiserfs /dev/hda2
debugreiserfs 3.6.11 (2003 www.namesys.com)

Filesystem state: consistent

Reiserfs super block in block 16 on 0x302 of format 3.6 with standard journal
Count of blocks on the device: 963063
Number of bitmaps: 30
Blocksize: 4096
Free blocks (count of blocks - used [journal, bitmaps, data, reserved] blocks): 427114
Root block: 8674
Filesystem is cleanly umounted
Tree height: 4
Hash function used to sort names: "r5"
Objectid map size 2, max 972
Journal parameters:
Device [0x0]
Magic [0x60aa06b]
Size 8193 blocks (including 1 for journal header) (first block 18)
Max transaction length 1024 blocks
Max batch size 900 blocks
Max commit age 30
Blocks reserved by journal: 0
Fs state field: 0x0:
sb_version: 2
inode generation number: 0
UUID: 467aea6f-16a8-445c-9f3b-7c8ef590894e
LABEL:
Set flags in SB:
ATTRIBUTES CLEAN
The number "Count of blocks on the device" indeed is number of blocks in the fs.
4. resizing underlying disk partition by fdisk(8) (size info is step 5)

for this section, precision is essential so if the original start sector is diff to the new one fdisk provides, use the original instead of the new

[root@haron root]# fdisk /dev/hda
First, we ask fdisk to show partition boundaries in sectors, not in blocks, because we need maximum precision there.

Adding Swap Space
with the partition shrunk, create a new swap partition as follows:

fdisk /dev/hda

n (new partition)

p (primary partition

+1000M (1GB sized swap)

t

82

w

all done!
mkswap /dev/hdb2
To enable the swap partition immediately, type the following command:

swapon /dev/hdb2
To enable it at boot time, edit /etc/fstab to include:

/dev/hdb2 swap swap defaults 0 0
The next time the system boots, it will enable the new swap partition.

After adding the new swap partition and enabling it, make sure it is enabled by using the command free.

debian global path (global environment variable)

2006-04-17T12:26:00.000+01:00

everytime I want to make changes to this, I forget its location :-s

to combat this, here's my bookmark:

/etc/profile

for those who have never done this in Linux before, but have in windows, you append things in the same manner you do in windows, using : as separators as opposed to ;

if you do not feel adventurous you can just add to the bottom of the file: export PATH=$PATH:/location/of/new/feature

this can also be added to individual users shell rc files (.bashrc for example) if you only want certain users to have the program in their path

alternativley of course, you could just add a symbolic link to /usr/bin :-)

like this:

cd /usr/bin
ln -s /path/to/program

be forewarned though, this only works for self-contained programs! so programs such as Azureus which use the path they were called from to locate its JAR files will not work using this!

a quick and dirty way to get scripts to start with the system in debian

2006-02-14T01:14:00.000Z

i appologise but i cannot remember where i found this as it was so long ago. this script is very quick and dirty and is useless past simple uses, if youre program requires a proper startup, restart and shutdown script then don't use this, YOU HAVE BEEN WARNED! i use it for my firewall. basically take a simple script such as the reboot (/etc/init.d/reboot) script and modify it to your needs, for me, it just points to my firewall:

#! /bin/sh
#
# reboot Execute the reboot command.
#
# Version: @(#)reboot 2.75 22-Jun-1998 miquels@cistron.nl
#

PATH=/sbin:/bin:/usr/sbin:/usr/bin

echo -n "Rebooting... "
reboot -d -f -i

converted to:
#! /bin/sh
#
#
#

PATH=/sbin:/bin:/usr/sbin:/usr/bin

echo "Starting Firewall and NAT"
/home/firewall-scripts/firewall

once created (and left in the /etc/init.d directory) call update-rc.d path/to/filename defaults to get it added to all the default debian startups, if you want to manually work out which runlevels it should start on, read the update-rc.d manual

this one's title isnt linked because i have made several modifications to the site where i originally learnt this, but i will link that site: http://yolinux.com/TUTORIALS/LinuxTutorialIptablesNetworkGateway.html, infact, i'll link the whole place because its good: http://yolinux.com/ and most specifically, the tutorials section: http://yolinux.com/TUTORIALS/

anyway, here's the example firewalls:

firewall:

# Delete and flush. Default table is "filter". Others like "nat" must be explicitly stated.
iptables --flush # - Flush all the rules in filter and nat tables
iptables --table nat --flush
iptables --delete-chain # - Delete all chains that are not in default filter and nat table
iptables --table nat --delete-chain

# Set up IP FORWARDing and Masquerading

iptables -A INPUT -p udp --dport 49152:65534 -j ACCEPT

iptables -P INPUT DROP # - Drop all other connection attempts. Only connections defined above are allowed.

echo 1 > /proc/sys/net/ipv4/ip_forward # - Enables packet forwarding by kernel
#--END--

this works for IPv4, when the IPv6 version becomes relevant, I'll post it :)
