Limited or no connectivity!

On Windows environment, this means that you are not connected in the internet or other network resources. This issue has many causes of why it is happen. Here's the following reasons:

1. On wired and wireless network your Dynamic Host Configuration Protocol(DHCP) is down, this could be your ..
a. Internet Service Provider(ISP)
b. Router
c. DHCP Server - could also be a proxy server

2. Using of incorrect Wireless Equivalent Privacy(WEP) key or absence of it

3. IP Address misconfiguration or corrupted TCP/IP

4. Faulty wiring or wrong cable termination

5. Faulty Network Interface Card(NIC)

To get rid on this issue, check the status of your connection by doing the following solutions:
a. Check your IP configuration, if using a static DHCP be sure that there is no conflicts on your settings. If you are using a static IP, check the following;

*IP Address
*Gateway
*DNS or Proxy

To check it, open your terminal or command prompt and type this...

ipconfig /all

This will list down all the configurations in your NIC adapter.
When there's no IP supplied by your DHCP server then try this command..

ipconfig /renew

If still there is a problem, try to ping your DHCP server or your Default Gateway or any workstation within your LAN.

ping IP Address (ex. ping 192.168.1.1 or ping ictpro.asu.edu.ph)

Still unsolved? Check the DHCP configuration on your server(Proxy), Router configuration, and your ISP configuration.

b. Check your hardware
*Wire or Cable - termination(e.g straight through, crossover, rollover etc.)
- when checking the cable, use other working cable to check if the problem is the cable
*NIC or LAN Card
*Switch or Hub
*Router
*Bridge
*Other devices you are using

Note! Replacing(hardware) with the working one when troubleshooting is the best way in finding trouble.

How to connect on remote computer

SSH(Secure Shell) and TELNET are the most commonly used tools in remote connection. The only difference between them is the security they possessed. SSH uses encryption in order to avoid eavesdropping, connection hijacking, and other attacks doing by hackers. Other tools are RLOGIN, VNC, and FTP.

Users of TELNET, RLOGIN, VNC, and FTP should not rely on these tools because during connection their password is transmitted across the Internet unencrypted. Through the use of sniffing tools, hackers could easily sniff you.

How to install Cinelerra

1. First thing you have to do is to edit the source.list. Open the terminal and enter the following commands.

deb http://giss.tv/~vale/ubuntu32 ./
deb-src http://giss.tv/~vale/ubuntu32 ./

These are for 32-bit users, and for 64-bit is,

deb http://giss.tv/~vale/ubuntu64 ./

2. Update your source.list by typing this command into your terminal.

sudo apt-get update

3. Now that your source.list is up-to-date it's time to install the cinelerra now.

sudo apt-get install cinelerra

4. The next thing you have to do is to edit the configuration in order to modify it's memory allocation.

sudo vim /etc/sysctl.conf

then, add this syntax in the last part of the configuration file

kernel/shmmax=0×7fffffff

5. To avoid restarting enter this command in your terminal and press Enter.

sudo sysctl -p

Then run Cinelerra now. If you encountered some error as shown below saying that......then maybe there is a problem on your sysctl.config.

WARNING! Cinelerra is running in 0x2000000, which is have a very low memory.

As a solution, open your terminal and paste this command and press enter.

echo "0x7fffffff" > /proc/sys/kernel/shmmax


When running cinelerra and you've encountered a problem like this...

cinelerra: error while loading shared libraries: libGL.so.1.2: cannot open shared object file: No such file or directory

Try to run this command to fix it.

sudo ln -s /usr/lib/libGL.so.1 /usr/lib/libGL.so.1.2
