I have a linux system which is conencted to a corporate lan and it has internet access to it. But i don think that machine hs any static ip or DNS name. I am able to ssh to that machine within the lan but is it possible to ssh to that machine outside the lan using internet?

I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).
I've been reading for days now, but can't find an example to the following. I have an ubuntu server, with two KVM virtual machines running ubuntu jeos. I want each VM to have it's own static IP, plus one IP for the server. How on earth I do that? do I need to create two bridges, one for each machine? and if so, how do I assign static IP to each?

I do know what a DNS server is (Courtesy of www.howstuffworks.com ) but I don't understand why the DNS servers must be changed simply because I chose to use a static IP address.. (My PC connects to the internet via a router.. )

View 6 Replies View RelatedI have an old pc that I would like to use as a headless server for my music, files, etc that I can access at work and other places outside of my network. I'm a complete noob in this department so please excuse my overwhelming ignorance. The only thing I've managed to succeed at was installing fedora 13. Two things in particular are giving me trouble: 1.)setting up my router and fedora box so that it has a static ip address and 2.)connecting to the fedora box via vncviewer on my laptop.
HERE ARE SOME QUICK SPECS THE DEVICES INVOVLED:
Fedora Box: Intel Pentium 4 2.66GHz, 1GB ram, Fedora 13
Laptop: Toshiba Satellite A505, Intel Core 2 Duo T6600 2.20GHz, 4GB ram, Windows 7 Home Premium 64-bit
Router: D-Link WBR-1310
ISP: Comcast (cable)
HERE'S WHAT I'VE DONE SO FAR:
Setting Static IP
On the fedora 13 box:
1.)Went to Network Connections and added a new connection
2.)Copied mac address from the default connection
3.)On IPv4 tab, added new address: 192.168.0.200 (this is out of the range which my router will assign automatically) netmask 255.255.255.0, set gateway to 198.168.0.1(router's ip on the network)
When I connect to this new connection web pages don't load, etc. but when I'm on the default connection I have no problems.
Connecting With Vnc Viewer
On the fedora 13 box:
1.)System -> Preferences -> Remote Desktop
2.)Under Sharing I checked "Allow other users to view your desktop" and "Allow other users to control your desktop"
3.)Under Security I unchecked "Ask you for confirmation", checked "Require the user to enter this password", and specified a password
On the router
1.)Set up port forwarding for port 5900, TCP only, to the ip address of the fedora box.
On the laptop
1.)Installed VNCViewer
2.)Went to whatsmyip(dot)org to get ip address of router
3.)Tried to connect to that address, port 5900 (ex. ##.##.##.###::5900)
4.)Connection times out everytime.
I recently used this process to connect my Samba network to be able to access and allow Windows XP machines to access my computer on my office network.
For various reasons, all the XP computers on the network are set to fixed (do we say static?) IP addresses with manual DNS. Hence I realised during the Samba setup that I had to set a static IP on my Ubuntu machine similar to my Windows static IP's (ie 192.168.10.?) in order to be able to see the Windows share PC's properly.
Once I set my Ubuntu machine to static IP of 192.168.10.3 with subnet of 255.255.255.0 and gateway of 192.168.0.1 then I was able to access and be accessed by PC's on the network. However I couldn't access the internet after this. I input the DNS server in the edit connections as you can see per the attachment. All these settings (except the IP address obviously) were all now exactly the same as the PC machines, and I thought I'd now be able to access the windows network, as well as have access to the internet, however, even though my wired network is connected there is still no internet access.
I'm using the GUI under network connections to make all these changes if that is important. I can't understand why this doesn't work?
My DHCP setting is disabled in fedora 12 . Previously i was using static IP address. I Want DHCP setting enable, any idea.
View 1 Replies View RelatedI set up a dhcp server in the lan and assigned static ips to two computers, computer A and B, according to their mac address. Everything was running fine. But when I turned off computer A, connected computer C to the network, and assigned computer A's static ip to computer C without changing dhcp setting. Computer C was able to access the internet. When I turned on computer A, dhcp couldn't assign an ip address to it, and computer C showed an error message of ip conflict and failed to use internet. I wonder if dhcp server is able to prevent other computer from using the same static ip that is already assigned to a computer according to its mac address.

View 3 Replies View RelatedI tried to setting a static ip from dhcp, I changed lines in /etc/rc.d rc.inet1.conf as follow:
# Config information for eth0:
#IPADDR[0]=""
IPADDR[0]="192.168.18.7"
#NETMASK[0]=""
NETMASK[0]="255.255.255.0"
#USE_DHCP[0]="yes"

DHCP_HOSTNAME[0]=""
and then I run "/etc/rc.d/rc.inet1 restart"
after that, can't access net, and couldn't ping the gateway[192.168.18.1], I have to change it back

I registered on Godaddy for a domain, and sucessfully setup URL forwarding. When I type in that domain it takes me to my website, but the browser shows the IP address again. Should I not be using "URL forwarding"? I'm guessing I have to do something on my server side saying what domain it is but I don't know which file to change and I am scared to touch anything. Although I'm a programmer, I'm not a network person.
I am trying to open a tunnel for a friend of mine who's isp has blocked a bunch of webpages, so I was thinking I would learn how to since it might come in handy in the future Anyway, so I looked at a couple of videos about going in to network settings and changing the setting to manual and write down the desired IP (in my case 192.168.0.137). Then I went into my router (it's a D-link DI 524) and tried adding my static IP as the DMZ computer. I then restarted, everything looked fine, the router saved the settings and the eth0 still hade the information saved so I wanted to try it out. I just googled "try my ports" and I found a website called [URL]...But no ports worked for me.. I tried double checking everything, checking for errors. I couldn't find anything so I'm guessing you might have a clue!
EDIT: It seemed I had to have a program that actually used the port for it to work.. It's working anyway, so if you could move it to [SOLVED] I'd be happy
If not should I just plug up directly into my modem?

how I can define a local static IP address (so that I can run a web server off of the same IP, rather than letting my router DHCP it)?I've tried doing the YaST->Network Devices->Network Settings->Traditional Method with ifup->Set NIC to desired IP->Set Default Gateway to router address method, and afterwards I can't even get into my router anymore (not even responding to ping).
View 8 Replies View RelatedI'm maintaining a very modest network at home, with OpenSUSE as OS on the server. I got the DHCP and routing working by following the instructions in the wiki. However, every time I run dhclient on the server/router, it appears my own DHCP server assigns an address to the internal network card despite the fact I specifically assigned it to be static using Yast. The situation resolves itself when I restart the network services with the command /etc/init.d/network restart. Otherwise no problem, but it also seems the internal network card gets a "new" IP from my server every time the external card requests one from the ISP. This is more of an issue.

I am in the process of setting up and e-mail system for my small business. In the past I have always had my ISP and my domain registrar handle the e-mail and just POP the e-mail to a ciient such as thunderbird. Now I have decided in order to better learn postfix or sendmail, I want to setup my own and administer it. My question is:
1 - Once I have my domain name for my company is the e-mail accounts just created via psotfix or sendmail or are the accounts created via my domain registrar like my domain name? For Example: my domain name is test.com and I wanted president@test.com.
2 - Are e-mail servers setup in a DMZ as realys and then forwarded to an internal e-mail server and them transmitted to the clients or are they normally just put inside the LAN?

After years with Linux and using ssh on a daily basis I have to admit I've never setup public/private key authentication and I've never run passwordless logon to ssh. It's not that I've never tried, I have - I've just never got it working. That to me is an almost alien concept as I am a tinkerer at heart and rarely stop until something is working the way I'd like it to. I get the principle of what's going on but I've always had a mental block about it.

I recently just upgraded from humble Linux user to confused Linux admin of my own virtual Linux server. When I issue the ifconfig command I get following output.
Code:
venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
The WAN IP of the interface is not really 1.2.3.4 I just changed that IP for security reasons.What I am trying to figure out, is it possible to assign a private IP address to the same interface or can I only have one IP address per interface. I understand I have a mask of /32 so I am not going to be able to subnet the address to create any more addresses, so I assume I am stuck with the WAN IP (public IP) that I have, and just need to deal with it.
The reason I ask this is because I have been reading through several DNS/BIND tutorials/walk-throughs, and a lot of them specify setting up a intranet access with 192.168.1.1 address for the local DNS server, but since I am connecting to the sever via SSH I figure I do not need a private IP address.
I'm running Karmic Koala on my laptop and I'm attempting to connect to my university's secure wireless network. I was directed here by the university's computer help websiteI've followed all the steps, but when I open the wireless network authentication applet and try to browse to my private key, I can't find it. The "chose your private key" window claims to be looking for "DER, PEM, or PKCS#12 private keys (*.der, *.pem, *.p12)," and while my private key file shows up as a .p12 file when I open that location with my file browser, the file doesn't show up when I try and browse to it from the authentication applet. I've attached an image which shows the file in one window, but not in the other f clarification.

The server has 2 NICs, one connected to the internet, and the other connected to the LAN. There is only one public IP. The computer I'd most like to connect to has a static, private IP. Anybody done anything like this or have any thoughts on how to get it to work?
