Networking :: Forward One IP Address To A Machine To Get Rid Of Nat
Apr 12, 2010My 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.

Mar 8, 2010I've a webserver at 10.10.0.55. Above in the hierarchy are managed network cisco switch / router and ASA firewall (the usual stuff). I also have a mail server at 10.10.0.200. I was told by the network admin that he can't forward port 80 to webserver and port 25 to mail server. Basically he said that it's a one-to-one (external.ip-to-internal.ip) mapping and all traffic, no matter what port it's destined for must go to 10.10.0.55. So, I turn to the wonder that linux is. The webserver is running Centos 5.4. Currently, all packets on port 25 are coming to the webserver. I want to forward all these packets to the email server. Note: the webserver only has one interface: eth0. I turned to web for help and did this in iptables:
Code:
$IPT -A FORWARD -p tcp -s 0/0 -i eth0 -o eth0 -d 10.10.0.200 --dport 25 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
It didn't work. I am assuming that since I only have one interface, a simple rule to the filter table and forward chain will not work.So i use the NAT table and try the following:
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
$IPT -t nat -A PREROUTING -p tcp -i eth0 --dport 25 -j LOG --log-prefix PortForward: --log-level 7
$IPT -t nat -A PREROUTING -p tcp -i eth0 -d 68.***.26.*** --dport 25 -m state --state NEW,ESTABLISHED,RELATED -j DNAT --to-destination
[code]....
First of all, since there is no service/daemon listening on port 25 on the webserver, is it even going to work? Isn't the webserver simply going to discard packets on port 25? I am assuming that packets go through the iptables first, and so iptables should route the packets to the email server, where there is postfix listening on port 25. Am i right? Also, as you can see in the code above, all packets coming on port 25 on the webserver should be logged. But they aren't. In order to troubleshoot, I'd like to at least know that packets are coming into the iptables. But since it's not logging, I can't find out what's wrong.

View 2 Replies View RelatedUbuntu Networking :: Way To Share Folder From Machine To Windows Machine
Aug 28, 2010I am trying to establish the easiest way to share a folder from an Ubuntu machine to a Windows machine.In the past I have added things to smb.conf and that has all worked fine but what I am trying to do is to figure out what the "new user" way of doing this is so that when I am helping other people I know I am getting them to do the simplest thing.I completely removed samba and reinstalled it so that I didn't have any configuration. Right clicked on a folder and selected "Sharing Options" ticked the "Share this folder box" gave it a name and a comment and ticked the other two boxes.
When I went to the windows laptop then it kept asking for a username/password and nothing worked.Back on the ubuntu machine I did sudo smbpasswd -a [username] and created a blank password. Now from the windows machine I can access the shared folder.Is the smbpasswd step still required? It's very confusing for a new user as there is no suggestion that anything other than right clicking on the folder and choosing the options you want would be required. Is it something to do with the fact that this is an ubuntu machine that has gradually been upgraded through versions and this problem wouldn't have been there from a new install?

Oct 31, 2009I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable. I have configured everything fine but don't know why till now can't ping!
A. Windows machine settings as follows:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.
B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :
1. /etc/sysconfig/network:
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
2. /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"
3. /etc/resolv.conf
nameserver 192.168.1.4
search locadomain
4. I restarted network service using this command:
/etc/init.d/network start
everything is fine. When checking using ifconfig command. I get the following:
eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr:........
[code]....
I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0). I did everything above and can't ping till now, when pinging from windows or Linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.

Fedora Servers :: Port Forward On The Fly Or At Startup With Virt Machine Manager And Kvm-qemu?
Jan 6, 2010I'm running some vm's in FC12 with kvm-qemu and using virt machine manager. I'd like to have some ports automatically forward on startup and be able to add redirections on the fly. Redirection on the fly is talked about here, but I am getting lost on what should be basic instructions.[URL]
As far as startup, In the past I just ran qemu from the cli and manually specified redirection with redir. I can't figure out how to do it with The virt machine manager which I am using to start my VM's now. I do not want the guests to see the host. From cli startup without virt machine manager, it looked like this: qemu -m 256 -hda vm.img -redir tcp:5555::80 -redir tcp:5556::445 &

Jan 11, 2011Just installed Ubuntu the newest release on my laptop . Im dual booting on my laptop. Vista or Ubuntu. I gotta say I love Ubuntu more than vista. I would much rather use ubuntu. My question is I cannot for the life of me connect to my main PC running Windows 7. Reason I want to do this is my PC running windows 7 has all my music which is rather large over 100gigs worth. Looks like it recognizes my PC but I cannot access anything.
Now In windows 7 I have disabled password and made it pretty easy to access files on there. When I boot into vista on my laptop no problem at all getting onto the network to access my main Windows 7 Pc. Any Ideas why Ubuntu can't get into my Windows 7 pc Through my network. Would love to do this that way I don't ever have to boot into vista. Ubuntu is great otherwise.

While "share files over the network" can and has been enabled, accessing the windows network has become painfully slow and my windows 7 machine still can't see the linux box

View 1 Replies View RelatedNetworking :: Ubuntu Won't Let My Windows Machine Into Shared Folders / Fix It?
Apr 13, 2011I configured Samba so that this laptop running Maverick would show up on the network so I could share files between the two. When I view the network on the laptop the windows shares show up, and I can access them; but when I view the network on Windows is when the problems start.
I view the network in Windows and this laptop shows up, but every time I try to open the Public folder (only folder shared) it won't let me in. I get some sort of Windows error message about being unable to access the folder and how I might not have permission to access it, and then at the very bottom it says something like 'file path not found'.
I tried to change the permissions in the properties for my public folder but I every time I tried to change the settings in the access box it would reset it back to blank (-) immediately after I changed it.
I'm not sure what the issue could be. Prior to purchasing this new laptop I was running Karmic on my old laptop and the networking between the two machines worked flawlessly. I'm hoping someone on the forum can help me with this problem.
Ubuntu Networking :: Obtain Write Access To A Windows Machine?
Apr 26, 2010For some time now, I have been backing up a windows box (data files only) to a ubuntu machine using the following:
mount -t cifs -o user=xxx,password=xxx //windowsshare/ /mnt/
For the first time I needed to restore some files and found I did not have the correct rights to write to the windows machine.
I had already wasted a whole day trying to map the ubuntu machine from windows and failed so this is not an option.
I have tried adding write rights to several accounts on the windows machine, also tried adding write rights to "everyone", checked both the share permissions, as well as the folder permissions.
I read about chmod, and tried to use the command gksudo to do something but this fails with DISPLAY error. Tried several things to fix this which didn't work and I was just going off on a tangent.
In the end I used a CD ROM to copy the files from one machine to another.
So for next time I need to restore a file, how can I give myself rights to do so?

Networking :: Can't Access Ubuntu Share From Windows 7 Machine / Resolve It?
Oct 8, 2010I am running Ubuntu 9.10 on my desktop right now. I have an external western digital terabyte drive plugged into it. I am able to see it and view it fine. Let's work with my music folder for example. I want to be able to access this music from my Windows 7 laptop so that I may add it to my itunes. However, when I enter the \servershare from the windows 7 laptop it says that the "server" is found but the "share" seems to be invalid. I've checked this 20 times and setting the share name to "music". I've rebooted 2 times on each computer yet to no avail. If I make a share on the Ubuntu desktop I can access it from the laptop. So it seems like it just gets lost when looking inside the external. This was just working last week, then I had to blow away they win 7 lappy and now it just won't work!

Apr 16, 2011I remember it being really easy to add a printer attached to another computer using Ubuntu, but I don't remember exactly what made it so easy. All I know is that now that I have switched to Kubuntu the process has become much harder because now I have to find out some special locations, numbers etc. for it to connect to the printer. It's connected to a Windows XP machine on the other side of the house.
It says alot about 'contacting the network administrator' if I am unsure about what to put in. But I am more or less the network administrator. how to find out what numbers to put in so that my Linux machine can connect and print to the Windows machine? Or maybe someone knows a few commands to share? I go to Applications > Settings > System settings, Printer configuration, New Printer, New Network printer, and then there are a few options but I don't know which one to choose. Windows Printer via Samba, I guess? Then in the box that says smb://[enter stuff here] I need to put in info but I don't know how to find that info.
