How To install Internet Gateway in Ubuntu with squid
use apt for instalation.user@server:~$ sudo apt-get install squid
please, backup file configuration (original)
user@server:~$ cp /etc/squid/squid.conf /etc/squid/squid.conf.backup
configuration file /etc/squid/squid.conf
user@server:~$ sudo nano /etc/squid/squid.conf
http_port 3128 /* listening port squid */
cache_dir ufs /var/spool/squid 5120 16 256 /*locate saving cache */
cache_mem 8 MB /* max memory for squid in memory cache*/
acl our_networks src 192.168.1.0/24 /* access list network client proxy is permitted */
http_access allow our_networks /* allow http access from network client */
cache_mgr webmaster /* configure cache manager */
visible_hostname proxy.network.net /* hostname in error message */
forwarded_for on /* configure transoarabt if anonymous proxy diset off */
another configuration is default. press Ctrl+O to saving, Ctrl+X for exit.
make directory cache with this command
user@server:~$ sudo squid -z
Restart Squid with comman
user@server:~$ sudo /etc/init.d/squid restart

Mounting Windows in Ubuntu
If you’re triple (or dual) booting Windows and Ubuntu, the Ars Geek web site’s got the lowdown on how to mount a read/write Windows NTFS drive.This approach uses an alternate method to the one Adam cited in his top 10 Ubuntu apps and hacks article. I’ve yet to build my Ubuntu workstation, so I wasn’t able to try this myself; also, NTFS support is still experimental so proceed with caution and a full-on working backup.

How to Mounting NTFS Partition in Open Suse 10.2
If you need only to see your files, then you don’t need to do anything as NTFS read only access is enabled in all versions of SUSE Linux / openSUSE by default.
For read/write you should add this repositories:
zypper sa http://download.opensuse.org/repositories/filesystems/openSUSE_10.2/ Filesystems
You will see following text:
* Adding repository 'Filesystems' Repository 'Filesystems' successfully added: Enabled: Yes Autorefresh: Yes URL: http://download.opensuse.org/repositories/filesystems/openSUSE_10.2/
Install the following packages:
fuse ntfs-3g
with
zypper in -c Filesystems ntfs-3g fuse
or go to YaST Software Management and install from there. To locate ntfs-3g use that as a search term.
Mounting NTFS Partition
By adding an entry to file /etc/fstab, the NTFS file system will be mounted automatically at boot. Make sure the mount point directory (in this example /Windows/C) exists beforehand. The most common case is that NTFS is on partition one of first hard disk:
- PATA (IDE) drive
#Device Mountpoint Filesystem Parameters /dev/hda1 /windows/C ntfs-3g user,users,gid=users,umask=0002 0 0
- SATA drive
#Device Mountpoint Filesystem Parameters /dev/sda1 /windows/C ntfs-3g user,users,gid=users,umask=0002 0 0
- Other options
#Device Mountpoint Filesystem Parameters /dev/disk/by-label/win /windows/C ntfs-3g user,users,gid=users,umask=0002 0 0
Make sure there is no “ro” command in the parameters before saving, otherwise the partition will be mounted read-only even though the driver has write support.
Alternatively, you can specify the source device using the disk’s ID (symlinks in /dev/disk/by-id/) or the filesystem’s UUID (/dev/disk/by-uuid/). by-label or by-id are preferred over /dev/sd* nodes because they will remain the same while the disk could show up under, say, /dev/sdc instead of /dev/sda (the latter of which depends on the order they were plugged in and/or recognized).
Manual mount
If you want to mount an NTFS partition manually, use the ntfs-3g command, specifying the disk partition as NTFS. For example this mounts an NTFS partition read-only which has the label “windows” onto the directory /mnt:
ntfs-3g -o ro,gid=users,umask=0002 /dev/disk/by-label/windows /mnt
This last part can also be done using:
su -c yast2 disk
Which is the same as YaST — System — Partitioner
