Networking :: Setup Pxe Server Routed Via Standard ASDL Router
Apr 2, 2010
I have searched google, but can't really get the hang of setting this up.Most howtos are setting up a DHCP and PXE on the same box. At the present my DHCP is done by my router and I want to set up the PXE server on my main PC.My router can re-direct traffic types based on ports (UDP or TCP) to an IP but can't do the bit about directing the pxe loader name (and I really don't want to ssh into it and start messing about there)If I redirect the port (what ever it may be, help required here) how would I go about setting up the Ubuntu PC to do the load and pass back to the PC trying to PXEboot?
Email my ASDL router IP for VPN connection.My adventure with NX nomachine continues with great success. Thanks for all you input and suggestions - I am still polishing the project but it has been straight forward to date.One questions I have is how to stay current with my ASDL router's IP. I use a Canadian provider with a dynamic IP that is constant for days at a time. Without powering my router down or any power outages, my IP will change. With that IP change, I am unable to login to my desktop.One windows style program I found does the job.It emails my current IP to a predefined email. I am unable to seem to find one for linux.
Ideally I would have a ubuntu program on my desktop (NX server) that would keep me up to date on my IP via email so I can login.Anyone have any experience with that? Or have any other suggestions on how to do this (I dont know the best way to keep that IP up to date besides requesting a static IP from my provider).
I have three machines say A B and C. I want to make machine B as a router for A and C, so that the ping packets from C to A should be going via B. I have directly connected two interfaces(eth4) of A and B and similarly two interfaces(eth5) of B and C. I have even set up a route between B and C. 1. But I am not able to set a route between B and A.2. If I ping A from eth4 of B(viceversa) it works. When I ping B from eth5 of C it work but not the viceversa.3. Also, if I ping from C to A, B receives the packets, but not A.
In addition to 2 "desktop" machines, I recently set up an Ubuntu Server with Apache2, but when I try to access my www.homepage from a machine locally connected to the same router (via both wired & wireless interfaces), I am directed to the Login page of the router, not to the www.homepage. Yet, when I access the www.homepage from elsewhere, my www.homepage is accessible.
I can browse to my www.homepage by entering the local IP address into browsers on both local machines, so I know the machines are talking to each other. Just not letting me get in via normal internet browsing channels.
Server: Ubuntu 11.04 Webserver: Apache2 Router: D-Link DIR-615 IP Address of: 192.168.0.110 (reserved on router, static on server)
I am planning to setup a home network with Ubuntu.the home network consists of ~3/4 computers; a mediaserver (reelbox) and 2 more PCs.Can I setup the server as a DSL router and get rid of my modem/router I have right now?
I have been searching google for a while now and have not found exactly what I am looking for. I would like to use my fresh install of ubuntu server 11.04 as my router/gateway for my home. I am not an expert at linux by any means but I can usually figure stuff out. I believe I need iptables, bind, and a few others probally. It eventually will also be a samba server but I have done a little with samba before. I do have 2 network cards, my router at the moment is starting to die and would love to have a more powerful router. I would also like to figure out how to do port forwarding in the router, as well as be able to see the load on the network cards. Maybe there is a program to show usage by user? As well as be able to do packet pritorization.
I currently have one of our clients set up to use a routed VPN for their 5 laptops to connect to the server remotley. And this works brilliantly. They are about to bring on a remote office that will need a VPN connection back to the main office, so I was going to set up a bridged connection between the two sites (and possibly more sites in the future).
So my question is whats the best way to go about this? Can I have one instance of OpenVPN running with tun0 set up for a routed connection to the laptops and add a second tun (tun1) to the config that will be for the bridged connection between the sites? Or am I going to have to run multiple instances of OpenVNP, one for the routed and another for the bridged?
If routed and bridged have to run in seperate instances, will I have to add another instance for each new remote site that needs a connection? Can a bridged config connect to multiple sites, or have multiple tuns in the one config?
I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I'm going to start a new thread because previous searches have not totally satisfied my question. I've read all day about doing this but each inquiry leads to discussion of configuring the router. I am also not network savy. I would like to set up an FTP server on my home computer (presently Ubuntu 8.10). I have only one computer. I am using DSL with my telephone line for internet connection. I do not use a router.
Is it possible to do this with no router and only a DSL ISP connection?
I've just finished installed a mail server with Fedora 12 + postfix + courier. I also have Squirrelmail and ISPConfig3 installed. The mail server is behind a router. I have [URL] pointed to the static IP at my router. My ISP has opened port 25 & 110 for me and my router has these 2 ports forwarded to my mail server (192.168.0.100).Workstations in local network can connect to my mail server and send emails with no problem but cannot receive emails from outside. I tried an email dossier and it saids connection timed out on smtp session. Do I need to include my static IP somewhere in the configuration so that it communicates to the world properly?
I am thinking of moving the router behind a server and connecting the server directly to the internet via a modem. Are there any security issues related to doing this? or other things I should be aware of. Iptables are implemented on the server blocking access on unused ports.
I would like to setup a Linux Router with Fedora. Here is what I have and would like to do...
Email filter device is on the LAN at 192.168.x.3. I need to provide SNAT to that device from both T1 interfaces...
All outgoing traffic will route through DSL except for traffic destined for addresses on either eth0 or eth1 (web sites).
I assume I would need the following:
I also assume I would need to setup iptables with FORWARDs for the 192.x.x.x networks to eth3.
What I am not sure how to do, is properly setup the incoming redirections so that the email filter can be access from both eth0 and eth1 by different IP addresses.
how to setup ubuntu as router. i already try to setup but it doesn't work.
my situation is to create ubuntu as router. i have two network card etho and eth1. i want to create eth0 in DMZ and eth1 only can only access in internal.
I have multiple devices in my garage that need internet connectivity. I have my main Netgear router inside the house. I have a computer running Ubuntu in the garage with dual NICs.
Here's a map of how I have it setup now: [URL] Here's my /etc/network/interfaces: Code: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.60 netmask 255.255.255.0 gateway 192.168.1.1
I was trying to keep everything on the same subnet. Eth0 is the external NIC, connected to the router in the house. eth1 is the internet NIC, which would go out to the devices in the garage. Now, I know it would be easiest to just connect a switch up and run all the devices in the garage off that switch. But the switch I have is a 10/100, and my network in the house is gigabit, and I want the PC in the garage to have gigabit access... which is why I'm doing this dual NIC setup and using the PC as a router, then the other devices in the garage will be 10/100.
In addition, I used the shell script as described in this article: [URL] to setup iptables. I also uncommented the net.ipv4.ip_forward=1 line in /etc/sysctl.conf. What am I doing wrong here? None of the devices in the garage that I connect up to the Ubuntu PC are getting connectivity. None are getting a DHCP lease from the main router in the house. The Ubuntu PC itself has internet access just fine though.
I am trying to set up SSH so that I can edit files on a home server (linux). I know this question has been asked many times before, but none of the answers seem to apply to me.
Here's my setup. I have the modem connected to a switch (wired) that connects 2 PCs to the internet (one desktop, one server, both wired).
All of the threads I see that discuss static IPs seem to require that I set up a router. Is this necessary? Can I still transfer files through a switch?
I want to connect to my office intranet without utilizing internet, there is aprox 210 ft distance and i cannot locate my N router's signal even when i installed the router outside of the building, the server is redhat enterprise, and want to share filehosting and internet with the office to cut down costs.
Office building with intranet>--------<210ft>----------my apartment
I am willing to invest some money in this setup but undecided how to extend the network, someone told me i can use a router in repeater mode but i cannot find any such router, my employer has allowed me to use the office network (so nice of him) but at my own setup.
I'm using a Debian box as a gateway. I'm planning on bridging my DLink 604T modem/router so that traffic on the LAN goes to my gateway (which only has one NIC). The Debian box is running a PPPoe application which I'm hoping to log into the ISP through the DLink. I plan to configure the box as a squid transparent proxy. Most Howtos I've seen use NAT with 2 NICs, eth0 for the LAN and eth1 for the Internet. Any step-through to set up NAT for this?
I would like to setup a qmail server for learning purposes (if you strongly feel Postfix is better, feel free to let me know). When I started setting up qmail (using Life with qmail), it suggested that having a DNS is the best approach. In the spirit of learning, I decided then to create another server for DNS only, and use that for qmail.
My problem is that, as this is a home installation, the internet is behind a Netgear DG834Gv5 router, on a DSL line that has a dynamic IP address. I am using DynDNS, but also don't mind having to update any DNS entries to keep up with the change, this is not exactly a production-grade setup.
In addition, I also have access to another DNS server where I can create authoritive entries for any domain I register. I have done that for a domain, and would like to point part of that to my home DNS so that I can learn.
So essentially, I would like to have a new zone for home.mydomain.org on my home DNS so that I can create new entries for *.home.mydomain.org such as qmail.home.mydomain.org etc. there.
I assume that this would include port forwarding on the router which is not a problem, but I truly have no clue where to start. I have a very basic install of Cent-OS 5.3 (no X and just Base a few admin and dev tools) and just installed the latest RPM of bind (9.3.x).
I've got an Ubuntu box set up as a router and wifi hotspot. I can access the internet and any website using this box. I can connect a laptop to my wifi access point, and connect to both the router box and the internet. I'm writing this message from it. If I access either hsbc Hong Kong internet banking or speedtest.net from my laptop I can't connect. Every other site I've tried is fine. What could be causing this? I don't know where to start. I've set up the firewall rules and routing tables, so I vaguely know what I'm doing... but clearly not enough to debug this issue.
\How can i setup my computer (currently running Ubuntu 10.04 lts) into a router so that other laptop can have a wireless connection to it and be able to access the Internet?
I have a linux server I'm intending to use as a firewall. The server has the following adapters
eth0 - Public IP (VLAN2) eth0:1 - Public IP2 (VLAN2) eth1 - 10.241.4.4 (VLAN4)
the Default gateway is my ISPs gateway. Additionally, I have the following route set: route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.241.4.1
I have a server that exists on VLAN 208 at IP 10.241.209.67/21., its GW is 10.241.208.1 (first IP in /21 range)
as it is on the 10.0.0.0/8 network, traffic from the firewall is successfully routed from that server through my router to the FW and out to the Internet. The FW can ping, ssh, etc... the server and vice versa.
I want an iptables rule that will allow me to forward port 4401 on eth0:1 to 10.241.209.67:4401.
Is this possible since the IP is not on the same subnet as eth1, even though it is accessible?
I'm a bit better than a neophyte linux user. I have not made port forwards with it in the past without scripts to assist so I'm looking for not just "it is possible", but also the syntax of how to add it.
I have a linux desktop with two connections - fast eth0 and slow modem ppp0. Most of traffic (e-mail, DNS, NTP) can be routed simply by IP/mask. But how about http and p2p (torrents, DC++)? Routing by IP is unacceptable, because there is very huge amount of routing rules. I need route http packets (80 port) through ppp0, p2p through eth0 (10000:65535 ports). I've found that splitting traffic by port is possible with marking packets for different gateways. For begin I cleared all tables and bringed up connections.
I am building a router and I wonder if I have some rules like this and /proc/sys/net/ipv4/conf/all/accept_source_route is 0 will it work.
Code: echo 1000 TEST >> /etc/iproute2/rt_tables iptables -A PREROUTING -s 192.168.2.0/24 -t mangle -j MARK --set-mark 1 ip rule add fwmark 1 table TEST ip route add default via 192.168.3.5 dev eth2 table TEST
I am not quite sure is it source routed packages at all. And also even if it works with my router will next firewall drop such packages. I have mentioned before that some things like:
Code: ip route add default via 192.168.3.5 dev eth2 src 192.168.2.0/24 do not work
1) it cannot see any networks around 2) i cannot setup it in master mode to use my PC as a router
As far as i can see, the device is recognized and the correct driver (rt73usb) is loaded. I was able to connect to a laptop somehow (the laptop could see other networks and the adapter's PC-to-PC network). I'd like to make it work as a router, i.e. share my internet connection (eth0) via wlan0. Here is what i have:
Code: Ubuntu 10.04 Linux 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux TP-Link TL-WN321G wifi usb adapter as seen as Bus 001 Device 006: ID 148f:2573 Ralink Technology, Corp. RT2501USB Wireless Adapter $ iwconfig wlan0 wlan0 IEEE 802.11bg ESSID:off/any [Code]....
Through yast2 I went to network services-->Mail server and took the standard option. My connection type is Permanent, filled in the outgoing server information and got to the incoming mail screen.
I told it to accept remote SMTP connections, open a port in the firewall and bypassed the downloading section since I just want to directly receive mail (I did however tell it I wanted a daemon to fetchmail). Told it to forward root's mail to me and a delivery mod of Directly. And finished.
The system sends mail out but I can't seem to receive any. What did I do wrong or what else do I need to do?
i had a very old server given to me. it's a Compaq Prosignia 200. it has a 166 pentium, more than 64 mb of ram(unkown because i see 2 32mb sticks and there are 2 more smaller sized sticks), a cd drive, a 6 gb hdd, and enough pci slots for 3 nic. i'd like to use it for a router for my 2 home pc's. i have no idea what im doing or if the hardware itself will run as a router. i do have a 25mb connection and dont really want to lose my bandwidth.probably too much to ask but i thought i'd give it a go.
I'm setting up a home network and trying to set up a Ubuntu Server (10.04) as a samba file server and a web server.I installed Ubuntu 10.04 Server and the automatic network configuration during installation failed. I've looked into host.conf, networks, interfaces, hosts and resolv.conf and either my settings are wrong or it's something else. I have a Win7 computer connected to same router and DSL modem and it works fine (edit: most of the time--- see below).
More information:
*ifconfig shows eth0 is broadcasting but without an IP address *route shows an empty routing table
Code:
sudo route add default gw 192.168.1.254 doesn't work: SIOCADDRT: No such process [code] sudo /etc/init.d/networking restart doesn't work:
