I am new to networking and trying to setup my own local area network using virtual box machines. I have installed BIND 9.7.3 using yum in Fedora (dns server) and created all necessary .conf and zone fil es. I am successfully able to resolve domain names on this host machine (dns server). for example dig @dns.domain.lan client1.domain.lan correctly resolves domain name.
I just installed open Suse 11.3, and I cannot SSH my school. Upon further investigation I could not even ping any machines outside my local area network. Ironically I could nmap machines outside my local area network.
I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
One question that weight a lot of points was about ethernet... the professor asked why ethernet is used only in local area network? resuming i wrote that ethernet is used only in LAN because it is shared and so for big network there could be a lot problem in using the shared channel.. for istance using protocol such as CSMA/CD, if a big network has a lot of hosts, they could wait a long time before sending...is it right or am I wrong?
At home I have two computers running linux connected to the same router. I would like to be able to connect them so that I can move files between them and execute simple commands. What is the most simple way to access a prompt on the other computer or to mount a partition currently used by the other computer?Using the www it is possible to connect two computers using ssh, but it should be easier to do this over the LAN, right? I have been googling a lot but not found anything.
I have a computer, the one I am on now, with Ubuntu 10.10, it should be completely updated... and I can network with other computers, I can access Windows XP and 7 shared locations on other computers, and I can also get Ubuntu on other computers to access this computer's shared files.What I can't do, however, is share my hardrives that are on this computer, I have tried sharing them in /media/ and etc, but it is not working, apparently you have to mount them in some mystical way.
Another problem is getting Windows machines to access Ubuntu computers on the network - which I believe is a Windows problem, so I can figure that out some other time, but importantly, I want to be able to share my hardrives over the network.
If someone can give me some instructions to mounting and sharing hardrives(internal), and even my DVD-Drives, and portable USB devices, would also be fantastic - since, in Windows you can just right click, "share", and it's done.. It is a very useful thing to have, and I don't want to use Windows on this computer anymore, but I have no choice, really, if I can't share my storage to the other computers.

I have made a cronjob, but it wont run, after some research i find out that my red hat does not see the cake console file.
When i type the command in the terminal i get the following: root@mydomain:/var/www/domains/mydomain/cake/console# cake -bash: cake: command not found
I searched here and on google what the problem could be and it seems that the $PATH is not set like it should, but i dont know how to fix it.
When i am in the console directory and echo $PATH, i get following: /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
I have a dual boot system (Linux and Windows) that I normally run headless and which boots by default into Linux (which is what I use mainly). This all works fine, except that on occasions when I want to boot Windows I have to plug in a keyboard and monitor just to select Windows in the initial grub boot screen. I'm wondering if there is an easier way to do this ? I don't mind if I have to boot Linux first, I just want to be able to reboot into Windows occasionally without having to plug in any peripherals.
This is a bit of an odd problem that's been happening to me recently. My home folder is a version of Fedora old, I've been using the same one between Fedora 11 and 12 (which I'm now using).
When booting up, I notice that my system fonts are not the ones I have manually set. They're the ugly version, whatever exact font it is. It's only when I select System->Appearances from the menu that the system seems to detect my seletions to use Liberation fonts in all areas, and then everything instantly switches to the more visually pleasing Liberation fonts. This is a strange bug, I was wondering if anyone has experienced this or can point me in the right direction?
I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)
I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).
I've already tried Seamonkey to create a web page but can find no way to create a web form in which I want to create form fields. Before moving to Ubuntu I used Microsoft FrontPage to create web pages with form fields. This was easy to do. what is available to do the same in Ubuntu?
We are using several printers on our Linux RH network to print customer invoices and receipts. Receipts are short forms of just 21 or 22 lines. Two of the printers (an HP LJ1300 and a Dell 5200) eject the receipt paper automatically; the other two HP (a LJ 4200 and a LJ2420) do not eject. You have to press the green button on the printer. Is there a solution to that? They are all set up with the same PCL settings.
I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.
However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.
Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?
we hav one of our client want access our company computer from outside network and all our computers are under proxy server therefore all computers have limited access so one of the limited access computer, client has to access from outside. so we want this computer should remain under proxy server as well as accessible from outside network
This may or may not be an easy question, as I'm somewhat uninformed in the networking side of computer science. I own a rented server with a static ip address. Is there a way that I can forward requests from it to my computer to setup a LAN network of sorts over the internet. Specifically, there is a program I would like to use that requires LAN (you enter an IP to connect to). Is it possible to setup my server in a way that users could connect to my server's ip, which would then forward it to my home computer (I'm fine with setting up my home computer with programs that would allow this) that could host?
I have been trying to remotely access another computer (which is outside my local network) with ssh and have not succeeded. I've done everything I've seen nothing to suggest and as I opened port 22 on both computers, I have ssh configured so as to allow access from any computer (with password) and tried to log in using the external IP (the encounter with these online pages of "what is my ip"), I have a firewall turned off, the pc from which I agree is Fedora 14 that I want to access MacOS 10.5.8.
I need this because I'm running a very heavy program at the university that I can not run on my personal laptop, but do not want to have to go every day to college for this.
I want to send mails to anyone in my local network. I have 20 machines with domain [URL]. I have installed sendmail in my machine with name [URK]. in /etc/sendmail.mc i had comment the DAEMON_OPTION line i redirect it to sendmail.cf restart the service.
I had mentioned the hostname entry in the host file of each pc.Iam able to send mail to all users in my pc. But I want to send mail from server1.example.com to station2.example.com,station3 etc. When I send the mail, it wont reach at the client side.
