Configure squid password access
(from http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch32_:_Controlling_Web_Access_with_Squid )
Password Authentication Using NCSA
You can configure Squid to prompt users for a username and password. Squid comes with a program called ncsa_auth that reads any NCSA-compliant encrypted password file. You can use the htpasswd program that comes installed with Apache to create your passwords. Here is how it's done:
1) Create the password file. The name of the password file should be /etc/squid/squid_passwd, and you need to make sure that it's universally readable.
[root@bigboy tmp]# touch /etc/squid/squid_passwd
[root@bigboy tmp]# chmod o+r /etc/squid/squid_passwd
2) Use the htpasswd program to add users to the password file. You can add users at anytime without having to restart Squid. In this case, you add a username called www:
[root@bigboy tmp]# htpasswd /etc/squid/squid_passwd www
New password:
Re-type new password:
Adding password for user www
[root@bigboy tmp]#
3) Find your ncsa_auth file using the locate command.
[root@bigboy tmp]# locate ncsa_auth
/usr/lib/squid/ncsa_auth
[root@bigboy tmp]#
4) Edit squid.conf; specifically, you need to define the authentication program in squid.conf, which is in this case ncsa_auth. Next, create an ACL named ncsa_users with the REQUIRED keyword that forces Squid to use the NCSA auth_param method you defined previously. Finally, create an http_access entry that allows traffic that matches the ncsa_users ACL entry. Here's a simple user authentication example; the order of the statements is important:
#
# Add this to the auth_param section of squid.conf
#
auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/squid_passwd
#
# Add this to the bottom of the ACL section of squid.conf
#
acl ncsa_users proxy_auth REQUIRED
#
# Add this at the top of the http_access section of squid.conf
#
http_access allow ncsa_users
5) This requires password authentication and allows access only during business hours. Once again, the order of the statements is important:
#
# Add this to the auth_param section of squid.conf
#
auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/squid_passwd
#
# Add this to the bottom of the ACL section of squid.conf
#
acl ncsa_users proxy_auth REQUIRED
acl business_hours time M T W H F 9:00-17:00
#
# Add this at the top of the http_access section of squid.conf
#
http_access allow ncsa_users business_hours
Remember to restart Squid for the changes to take effect.

linux tips and tricks
- check the cpus bogomips :
$ cat /proc/cpuinfo | grep bogomips
- compare directory tree :
$ diff -r --brief /mnt/old /mnt/new
- copy file from directory tree, recreating the tree :
$ find ./ -name [makefile] | cpio -pdmv [/path/to/be/copied/to]
- HDD speed benchmarking :
/sbin/hdparm -tTf /dev/hda
- Scan the disk for bad blocks : unmount the partition (remount as readonly if necesary)
# fsck.ext3 -c -c -v -y /dev/sdb1
Set time from ntp setver :
# ntpdate -u -b -v time.nist.gov

Ubuntu iscsi target tutorial
Download the iscsi target from http://iscsitarget.sourceforge.net/
wget http://surfnet.dl.sourceforge.net/sourceforge/iscsitarget/iscsitarget-0.4.16.tar.gz
compile :
tar -zxvf iscsitarget-0.4.16.tar.gz
cd iscsitarget-0.4.16/
make
I had to install :
apt-get -y install libssl-dev
make install
check that it starts :
cd /etc/init.d/
./iscsi-target start
./iscsi-target status
prepare a storage file (or use whole sd device)
cd /var; dd if=/dev/zero of=dev_iscsi_01.bin bs=1m count=100
this made a 100mb file
edit the iscsi target config file :
vim /etc/ietd.conf
change add the following lines :
Target iqn.2001-04.com.example:storage.disk1.sys1.xyz
Lun 0 Path=/var/dev_iscsi_01.bin,Type=fileio
restart the iscsi service :
/etc/init.d/iscsi-target start
connect from windows iscsi initiator and open the storage manager

recovering a disk with bad sectors by copying it to another disk with linux
In this tutorial example the dump is from hda to hdb (the hdb disk has to be same size of larger)
# dd_rescue -A -v /dev/hda /dev/hdb
map bad sectors on a mounted ext3 partition tutorial
Mount partition as readonly :
# mount -f -r -o remount /dev/hda1
(replace had1 with your mounted ex3 partition)
Scan and mark badblocks :
# e2fsck -c -C 0 -y -v /dev/hda1
(replace had1 with your ex3 partition)

mount a directory in another directory (ln -s replacement that works inside chroot)
To allow access to other directory/file from apachee/ftp chroot where ln -s dosent work use :
mount --bind olddir newdir
from mount man :
Since Linux 2.4.0 it is possible to remount part of the file hierarchy somewhere else. The call is
mount --bind olddir newdir
After this call the same contents is accessible in two places. One can also remount a single file (on a single file).

Installing Ubuntu hardy alpha-3 on Lenovo / Ibm ThinkPad T60
Problematic hardware on my specific machine variant :
Intel 82573L copper NIC
Atheros AR5418 wifi NIC
ATI Radeon X1300 Display
1. get the ubuntu as the kubuntu power managment dosent work (didnt check the other variations)
2. check your hardware : sudo su -; lshw | less
3. Install the Intel copper NIC driver for the Intel 82573L chip : http://downloadcenter.intel.com/Detail_Desc.aspx?strState=LIVE&ProductID=983&DwnldID=9180&lang=eng
(follow the instructions, connect the cable before the make / make install or else the phy is powered down to save power)
4. Install the Atheros AR5418 wireless network driver : get the latest driver source from the http://madwifi.org/ svn and compile/isntall per instructions, reboot and use the network manager to configure the wireless network as usual.

HowTo: Emergency Reboot a Remote Machine
http://portal.itauth.com/2007/10/29/linux-howto-emergency-reboot-remote-machine
The first step is to enable the SysRq system, if it's disabled:
echo 1 > /proc/sys/kernel/sysrq
Now you can reboot (instantly, be forewarned) if the machine is hung:
echo b > /proc/sysrq-trigger
LatencyTOP
http://www.latencytop.org/
LatencyTOP is a Linux tool for software developers (both kernel and
userspace), aimed at identifying where system latency occurs, and what
kind of operation/action is causing the latency to happen. By identifying
this, developers can then change the code to avoid the worst latency
hiccups.

Compiling emule that dosent upload - leecher mod
Visual Studio 2005 is needed to compile emule.
The easiest way to compiling emule is to download the emule source together with the libraries, the best one is emule-morphXT mod :
http://emulemorph.sourceforge.net/modules.php?name=Downloads&d_op=viewdownload&cid=2
Moding emule for no upload :
Find the file : UploadQueue.cpp
in it change the function :
"void CUploadQueue::AddClientToQueue(CUpDownClient* client, bool bIgnoreTimelimit) {"
add a "return;" below the declaration so that the function return immediately.

installing squid on windows
Download squid for windows from :
http://squid.acmeconsulting.it/download/squid-2.6.STABLE18-bin.zip
Read the installation instructions in the documentation.
Change the c:\squid\etc\squid.conf from the default :
acl home src 192.168.0.0/255.255.255.0 # (change if different network subnet)
http_access allow home
cache_dir aufs c:/squid/var/cache 1000 16 256
dns_nameservers 208.67.222.222
run the following commands :
mkdir c:\squid\var\cache
c:\squid\sbin\squid -z
Done, run squid :
squid
configuring squid proxy on ubuntu
$ sudo su -
# apt-get install squid
# vi /etc/squid/squid.conf
configure the proxy port to 8081 (this the port that needs to be configured in the browser)
search for "http_port" and change to "http_port 8081"
configure the cache to use 2GByte storage
search for "cache_dir" and change to "cache_dir aufs /var/spool/squid 2000 16 256"
(change the storage type from ufs to aufs, explanation from the squid.conf file :
# The aufs store type:
#
# "aufs" uses the same storage format as "ufs", utilizing
# POSIX-threads to avoid blocking the main Squid process on
# disk-I/O. This was formerly known in Squid as async-io.)
configure the access list for example :
acl our_networks src 192.168.0.1/24
http_access allow our_networks
start squid :
# /etc/init.d/squid restart
