Jan 21, 2011Within Windows you can do a reverse ping using the -a switch. I.e., ping -a 192.168.x.x. and it will return the system name.

CentOS 5 :: Switch To Root In Terminal?
Oct 19, 2009I just installed CenOS 5 on my server and am in the process of installing some software to the machine.
I understand repositories and was able to get it all set up for installation with the yum command.
My problem is that when I attempt the install, it says i need root access to install.
I tried using sudo commands to switch to root access, but after entering the password, it says my username isn't allowed root and that my actions will be reported.
I am the admin for the system and have total control, I just don't know how to switch to root in the terminal.

Jul 27, 2011I have router based on CentOS system with DHCP server. In one eth I have fiber converter attached in second one I have Cisco Catalyst switch connected. From the switch rest of ports are used to provide internet traffic to rest of network. I wanted to divide each segment of network (based on switch ports) that they don't see each other (it'll be good for me if someone will connect his wireless router to the network not to WAN by LAN port and start be a second DHCP server). So my network configuration:
CentOS:
DHCP with range 10.0.0.1/8 network
Switch ports
1 - CentOS DHCP
2 - second server
[code]....
Parts of networks I've assigned IPs 10.network_part.subnet_part.client_ip so I have addresses for clients: 10.1.1.2/8, 10.2.1.3/8, 10.3.0.4/8, etc ...
I've decided to give each port it's own VLAN like below:
Port / VLAN
1 / trunk
[code]....
I've configured switch ports by using:
(config)# interface Gi0/Port_Number
(config-if)# switchport access vlan VLAN_NUMBER
[code]....
And after doing that whole network stopped working. I think that cisco part of configuration is OK (at least customer ports, I don't know if there is any additional info needed for trunk port). On CentOS router I didn't setup anything regarding VLANs ...
CentOS 5 :: Remote Shutdown Server Through Power Switch?
Jul 13, 2009I have built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.
I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?
The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.
CentOS 5 :: Commands After Screen - Using ./hltv To Switch Directory?
Oct 7, 2009I'm running a Counter Strike 1.6 Game server on my centos 5 VPS.

So I do the following and it gives me errors then. screen -A -m -d -S hltv ./hltv My question is, do I need all of those commands after screen? I just simply want it to not close once I exit Shell.

Mar 11, 2010I followed the instructions on this page ([URL]) in order to secure my sshd and prevent anyone form accessing the server directly as root. Therefore I changed the "PermitRootLogin yes" to "PermitRootLogin no" and restarted sshd. After that root access was denied directly but for some reason I am unable to switch to root from any of the normal user accounts with "su -" because I keep getting the "Incorrect password" errors. I am sure that the password is correct but for some, to me unclear, reasons I am unable to access the root account over SSH from a normal user account. I also noticed that after that I lost the ability to access the server as root over SFTP. why I am unable to generally use the root account after doing the named changes to sshd_config/ I am running CentOS 5.4 with the newest update.

View 4 Replies View RelatedCentOS 5 :: Switch Between Full-screen VNC Instances With One Keypress?
Oct 9, 2010OS: Centos 5.4
VNC Viewer Free Edition 4.1.2 for X
Switching between two instances of VNC viewer in full-screen mode takes three key presses and two mouse clicks. How can the viewer be configured to pass a special key combination to the host operating system instead of the remote OS, so it's possible to switch between full-screen viewers in one key press?
e.g. With the default configuration, if I put the viewers in adjascent workspaces, then the sequence to switch is: F8 MouseClick Ctrl+Alt+Left F8 MouseClick If the key combination Ctrl+Alt+Left was passed to the host then it would be possible to switch workspaces (and therefore viewers) in one key press. When working on multiple remote machines, both physical and virtual, it's often necessary to switch between them frequently. I must switch over 100 times some days. Simplifying the key sequence would be both quicker and more intuitive.
CentOS 5 Networking :: Spontaneous Static IP To DHCP Switch?
Jan 7, 2011I had something I think if very odd happen to one of my computers at work today, it appears to have spontaneously switched from having a static address set to getting its address by dhcp.this is a small office with a mix of mostly linux servers and desktops with a few stand alone windows computers, mostly notebooks. Most of the desktop computers get their address by dhcp, they all have NIS /NFS for remote mounted home directories (interchangeable desktops so anyone can log in at any desk). The particular desktop computer in question here has a shared printer on its parallel port, so has a static IP. Yesterday a UPS in the server rack died, after pulling it and plugging things back in and restarting the servers, it was easiest just to reboot all the desktops, everything came up ok including the desktop in question, and the printer did work.
Today I pulled the oversized UPS from this desktop to replace the dead one, and put a more appropriately sized one in its place, shut the servers down again, rebooted, etc,About an hour later someone tells me the printer is not working on the desktop, and after a lot of searching I find this desktop has the wrong IP address, I ran system-config-network and it showed the address was set to dhcp, I changed this back to the correct static IP and things seem to be working ok now.
CentOS 5 Networking :: Multiple NICS In Same Machine Connected To The Same Switch?
Dec 8, 2009I have a program that attaches to an interface. I can run two copies of the program on two systems (each running one instance), connect it to a switch, say 1.1.1.1 & 1.1.2.1. In this configuration two instances of the program can communicate and everything is fine.
Now, to reduce cost, it want to use only one system with two nics connected to the same switch, running two instances of the above program, each instance attached to two interfaces respectively on the system. I have the following settings:
eth1 Link encap:Ethernet HWaddr XXXXXXXXXXXXXXX
inet addr:1.1.1.1 Bcast:1.1.1.255 Mask:255.255.255.0

General :: Switch Between Computers Using KVM Switch?
Mar 14, 2011I am using a Fling KVM switch (by Belkin), to connect 2 computers to my monitor One computer is running XP and the other is running Linux. My wireless switching mechanism has just gone the way of the saints but Belkin has supplied a software solution for this occurrence. There is a small app called Fling (surprising) that allows me to switch from the XP machine to the Linux machine but nothing to switch back to the XP. What I need to know is there a similar app for the Linux computer. (NB I have tried Synergy but have no idea how to set it up - I've been told that synergy might work).

Now my question is this, would this be a problem? There is some specific procedure/best practice I should follow? Or once compiled and configured Postfix I can safely disable/uninstall sendmail?

Aug 24, 2010Is anyone using a kvm switch without any problems? I've been dealing with this for 3 years now & still haven't solved it. I've got two different kvm switches & they both have the same problem. Ubuntu no matter what version will only work correctly on the first port. The two switches I have are a 2- port trend-net & a 4 port Alluratek, they both do just monitor,keyboard & ps2 mouse. The problem is only with the monitor. The resolution is stuck at 800/600 or else it only covers part of the screen. After messing with xorg forever in Hardy I finally got it working but upgrading to 10.04 I just give up. Windows never has a problem detecting my monitor with the kvm switches but Ubuntu does.

View 7 Replies View RelatedUbuntu :: USB KVM Switch In Use?
Jan 15, 2011Currently running a Windows XP computer and an Ubuntu computer through a new TRENDnet 2-computer USB KVM switch, a wireless laser mouse and a brand new GigaWare multimedia USB keyboard. A 20-inch picture tube.
I can switch between computers using the buttons on the switch, and I can use the universal hot-key command on the Windows side to switch to Linux, but the universal command won't work on my Linux computer. The universal command is two presses of the Scroll Lock key in succession.
In Windows, the Scroll Lock light comes on, on the first press and goes off on the second, as I switch computers. In Ubuntu, the scroll lock light never lights.
The Windows computer is a 2002 model HP, 2.6 GHz Pentium 4, while this computer is similar to the K7S5A mainboard, different manufacturer, 1 GHz Athlon processor.
Any programs, commands or anything I might use on Ubuntu to determine the status of the keyboard's scroll lock, or would that more likely be a bios issue?
Edit: TRENDnet TK-207K kvm model number.
