Networking :: Determine The IP Address Of A Machine?
Apr 6, 2009
I'm just an undergrad with duck tape and google searches to hold this place together. Anyways on to my question. Where I work, we have a tape library but no way to configure it, the backup software simply talks to the robot to load and unload tapes. There is a network port on the library and I do have the software, but have been running into problems getting access. I was wondering, is there a way to determine the ip address of this machine by plugging in a cross over cable with a laptop and scanning it? What tools could I use to do this?
I am tring to get my linksys wireless router to connect to my laptop that i recently installed Fedora 10 on. Well it is actully running of an external HD. Any way when i boot in windows it connects and works fine, but when i try to activate wlan0 it says "Cannot activate network divice wlan0!" "determining IP info failed..."
I had had my internet connection working using PPPoE, but after I did some tweaking and configuring on the machine (configuring Samba), I wasn't able to connect to the internet and on the syslog said:Code:Cannot determine ethernet address for proxy ARPI'm using dynamic IP address on my internet account. Is this problem related to Samba server configuration that is running?
My ISP can give me up to 5 ip addresses. Is it possible to "forward" one of them to a machine to get rid of nat? I was thinking of "forwarding" one public ip to my machine and let the rest of the network share one ip using nat.
I tried to authenticate using ntlm proxy authentication service and my computer could not retrive the IP address. Currently I am using fedora cammbridge
I am doing a test on MAC learning and for that ,I need to change my MAC address of linux machine while the interface is UP. To be more clear, consider eth1 in a fedora core 8 machine. And while the interface is UP. I am running a script which changes the MAC address from 10:1:1:1:1:1 to 50:50:50:50:50:50 (i.e 50 times MAC address is changed) . When I try to change the MAC address when the interface it UP, it gives me the following error :
siocsifhwaddr : device or resource busy
I know the way of changing the MAC address by bringing down the interface but I need to know if this can be done while the interface is UP.
I am running Ubuntu 8.04, and I am able to access my machine via SSH, but I only want the log in screen visible on the machine itself, yet still able to work with the SSH. But to do this, I have to log in, get the IP address, log off, then log in via SSH. How do I make the machine receive an IP address during the boot-up!
i want to know mac address of a particular ip but the problem is that i am unable to ping that ip but that ip is being used by someone in my local network that i know from my proxy logs. i want to know the mac address of that ip,
I want to setup 1Gbps our lab network and we purchased 'Buffulo Giga layer switch ' with 24ports. Is there a way to tell DHCP to assign specific IP to a particular MAC address of a machine ? We want to use DHCP and whatever the port we use ,it should have same IP ..
I have an odd thing going on with DNS. I have two machine's running Ubuntu and for some reason they do not always resolved internet addresses on my Internet connection. This has gone on since the Ubuntu 8.04 when I first started using Ubuntu. Anyway, I use OpenDNS' DNS servers and I have been running perfectly.
This is what is odd. My Windows XP Machine never has the problem. It always resolves. Does Windows Possibly have some Microsoft hosted DNS server hard coded in there as a backup? Things are working fine this way so I am not looking to change. I am just a little puzzled and finally got around to asking, "Why is this".
I am accessing a remote DB using JDBC from inside a java program. is there any terminal command with which I can see the remote machine's ip/mac address?
I want to make make my fedora machine access-able over the internet. I want to assign IPV4 address to this machine( I already have one IP address ) which can be used for this. What configuration changes I need to make in fedora to make it accessable to the external world
i am new to linux . i have the basic knowledge of networking. a week ago i installed debian Lenny version on an old pentium 3.in addition i installed a ddclient configured it according to many tutorials....i searched google a few days but didnt find my case.i ran the folowing command :

I have an HP Laserjet 3.I can use it in normal Windows mode, or as a Postscript printer.it is an older printer, but it is still listed in the driver database. The cups setup tool cannot autodetect this printer. Also, if I select the actual driver for this printer, the cups tool still reports that no printer has been selected. I cannot add that driver for some reason. So, now I have to become an expert in cups configuration. Where is the cups HOWTO? Not in the SuSE howto section. Online? A little support there, but not SuSE specific. Does this local printer need to be a "network" printer? If so, how to I determine what internet address to use?
First, (for samba) how do I determine whether my computer "gets IP address information from a dhcp server on the network," and whether "the dhcp server provides info about WINS servers ("NetBIOS name servers") present on the network," and consequently whether a change to my smb.conf file, "so that DHCP-provided WINS settings will automatically be read from /etc/samba/dhcp.conf," and whether the dhcp3-client package must be installed?
What is the best way to determine in Linux if a multi-processor machine is overloaded? I thought load was a good measure but I run a large number of tasks which don't consume a lot of CPU but which drive up the load. A 4 processor machine has a load of 66 right now according to top for example but mpstat reports that the all CPU idle time is 89%.
I am connecting to linux server(RHEL4.7) using putty from my windows machine. Is there any way to get the ip address of my windows machine using C program in linux.
1) I'm not sure which IP address to use when I list my machine name in /etc/hosts, particularly after reading:
Quote:
By the w]ay, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1 # should NEVER be named with the name of the machine. It causes problems # for some (stupid) programs, irc and reputedly talk. :^)
Here's what I have now: Code: root@eagleswing:~# hostname eagleswing root@eagleswing:~# cat /etc/HOSTNAME eagleswing.5binc
[Code]...
I'm not certain how to include my router in /etc/hosts so I can use it to link my PCs as stated above. I was thinking of writing (see above link):
192.168.2.1 localbelkin Will this work & is it proper?
3) Do I need to make use of any other IP addresses at this link? What are the WAN IP & Default Gateway addresses used for? I am going to be serving documents & running scripts on Apache.
Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.
I am working on implementing a protocol on NS2.34 .I really need help to solve this problem . Actually , I don't now whether the problem is generated by the tcl code or the c++ code when I run the simulation, I get this result :
Code: num_nodes is set 64 INITIALIZE THE LIST xListHead 34 45 channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 550.0 SORTING LISTS ...DONE! code....
Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
I'm running Ubuntu 10.10 and I'm having problems trying to assign it a static IP address. No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.
