Evince papersize

Add the a line with
LC_PAPER="en_HR@hrnum"
in
/etc/environment
Evince will use A4 as default paper format after your next login.

What is en_HR?

en_HR is locale meant to be used by computer users whose native language is Croatian, but who are primarily used to US English based interface. Therefore en_HR features US English messages, and US style of writing numbers. US numeric style is chosen because of the decimal separator - in US style the decimal separator is `.', which is commonly used in mathematics and by SI, while Croatian decimal separator is `,'. If you would rather use Croatian numeric style, then use en_HR@hrnum instead of en_HR. Collate, ctype, monetary, paper, telephone, measurement, name and adress settings are the same ones from hr_HR locale. Date and time format conforms to ISO 8601 standard.

ssh tunel from linux

ssh -L 8080:192.168.2.254:80 user@address.org -p 22



Open your browser and go to http://localhost:8080 to see if your tunnel is working.

ssh -L localport:host:hostport user@ssh_server -N

where:
-L - port forwarding parameters (see below)
localport - local port (chose a port that is not in use by other service)
host - server that has the port (hostport) that you want to forward
hostport - remote port
-N - do not execute a remote command, (you will not have the shell, see below)
user - user that have ssh access to the ssh server (computer)
ssh_server - the ssh server that will be used for forwarding/tunneling

Without the -N option you will have not only the forwardig port but also the remote
shell. Try with and without it to see the difference.

Note:
1. Privileged ports (localport lower then 1024) can only be forwarded by root.
2. In the ssh line you can use multiple -L like in the example...
3. Of course, you must have ssh user access on secure_computer and moreover
the secure computer must have access to host:hostport
4. Some ssh servers do not allow port forwarding (tunneling). See the sshd man
pages for more about port forwarding (the AllowTcpForwarding keyword is set to
NO in sshd_config file, by default is set to YES)...

Example:


ssh -L 8888:www.linuxhorizon.ro:80 user@computer -N
ssh -L 8888:www.linuxhorizon.ro:80 -L 110:mail.linuxhorizon.ro:110 \
25:mail.linuxhorizon.ro:25 user@computer -N


The second example (see above) show you how to setup your ssh tunnel for web, pop3
and smtp. It is useful to recive/send your e-mails when you don't have direct access
to the mail server.

For the ASCII art and lynx browser fans here is illustrated the first example:

+----------+<--port 22-->+----------+<--port 80-->o-----------+
|SSH Client|-------------|ssh_server|-------------| host |
+----------+ +----------+ o-----------+
localhost:8888 computer www.linuxhorizon.ro:80

...And finally:
Open your browser and go to http://localhost:8888 to see if your tunnel is working.

ltsp - xserver configuration

first in /etc/ltsp/dhcp.conf add/change this line: option root-path "/var/lib/tftpboot/ltsp/i386";
dhcp example:

authoritative;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.200 192.168.0.250;
option domain-name "example.com";
option domain-name-servers 192.168.0.150;
option broadcast-address 192.168.0.255;
option routers 192.168.0.150;
# next-server 192.168.0.1;
# get-lease-hostnames true;
option subnet-mask 255.255.255.0;
# option root-path "/opt/ltsp/i386";
option root-path "/var/lib/tftpboot/ltsp/i386";
if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
filename "/ltsp/i386/pxelinux.0";
} else {
filename "/ltsp/i386/nbi.img";
}
}


Then edit your /var/lib/tftpboot/ltsp/i386/lts.conf file.
Example:

[00:12:FB:01:74:AF]
# LDM_AUTOLOGIN=true
# LDM_USERNAME=ucenik01
# LDM_PASSWORD=ucenik
SOUND=False
XSERVER = sis
X_MODE_0 = 1280x1024
X_MODE_1 = 1024x768
X_MODE_2 = 800x600
