If I want to see what ports are open on a particular device I just run nmap 10.6.56.244[/code] it comes back with which ports are open. very handy

If you log into your server via ssh ssh [email protected] You need to create and store a vnc password x11vnc -storepasswd yourpasswordhere/etc/x11vnc.pass If you are using kubuntu then edit the Xsetup nano /etc/kde4/kdm/Xsetup At the end of the file add /usr/bin/x11vnc -noxrecord -noxfixes -noxdamage -rfbauth /etc/x11vnc.pass -bg -o /var/log/x11vnc.log -forever -rfbport 5900 Then reboot your server and you should have x11vnc started upon a reboot before anyone logs in.

You may also want to try the following command... its much faster for copying so its great for that initial copy and then use your rsync command afterwards. tar -c /media/crates-17 | ssh 192.168.1.77 'tar -xvf - -C /home/backups/crates' Try this for rsync rsync -avW -e ssh /media/crates-17 192.168.1.77:/home/backups/crates

That system looks nice but I thought lower band radio frequencies transmit through building materials easier than higher band frequencies. So you may want to look at NLOS (non-line of sight) when going through trees. There is also nLOS (near Line of Sight) which means you can see the other end but it may have few trees. I would suggest this unit http://www.gnswireless.com/GNS5511C_Motorola_900Mhz_Wireless_Bridge.htm or http://www.gnswireless.com/GNS1135.htm

I would like to establish an LDAP server on a CentOS server but figured I would post this in the General Technology Discussion because LDAP works on all operating systems and I am just confused on everything LDAP but know that everyone uses it. My goal is going to be to utilize this LDAP server for authentication from web servers, switch and router login, and anything else I can find that needs to authenticate a user for access. Could someone help me understand it better? I personally will be using OpenLDAP

So we traced the IP address of this flooding virus in the network to a hide nat hosted on an ATT Firewall? Anyway to troubleshoot this from our LAN side?

After the xp logo screen the screen goes to blank and it just hangs. This looks like a graphics card fault but changing card does nothing. Booting into safe mode and it stops at agp driver. Repairing windows gives a lsass.exe error which cannot be resolved. Scanning hard drive reveals no viruses. So far we have had to reformat and reload xp - but I just got another computer with same fault symptoms. I'm wondering if anyone has similar findings and have they discovered cause/fix. There is a small possibility that an av update may have been cause, but no way to confirm this.

Thank You for your help , some really good information.

Ohh, I see. I have the stackwise cables but don't have a long cable to connect the bottom to the top so I'll have to get one of those. How expensive is the redundant power supply and does it come with the DC cables needed to connect the cisco switches together?

Okay, so I have multiple 3750's and would like to "stack" them for the purpose of redundancy. Any suggestions on how to connect the stackwise cables? :confused:
