I have a program that connects to the internet that I would like to route through one of my secondary network interfaces. I need one specific port routed to eth1 instead of eth0. I believe that I should be using iptables for that, but I don't really know how to do it.
Do we really need the lines if I am allowing any machine to connect? And I have only 1 network card. This is acting as a dedicated TFTP server.I ask as I get an error on the get and put commands as below:
tftp> get xxx.txt tftp: error received from server <File not found> tftp: aborting
However although it gives an error it DOES GET the file.The put command however does NOT put the file. I have nobody / nogroup setup for the directory permissions as well.
tftp> put .vimrc tftp: error received from server <File not found> tftp: aborting
im trying to setup a tftp server on red hat linux. Ive gone through like all the instructinos online. And like i didnt get any errors or anything when typing the commands on the terminal but basically every time i try to test it i never works sooo im not really sure how im suppose to do this. basically i have a tftp in one ip address. And with another system with a different ip address using the client tftp ipaddr(server) and i try to get foo and it never connects and I tried a ping and they ping together just fine soo im just not sure if the tftp server is even on
You are running tftpd as an on demand server i.e. it is only fired up when it is needed. Services run by xinetd are always run on demand. Have you actually tested if tftp on another system can access your PC i.e.
I've tried to configure DRBL server to use Clonezilla and that is required me to setup DHCP, TFTP servers.But I've gotten a lot of errors from them - so please look at my attachments from /var/log/messages and dhcpd.conf - help me to find out what are wrong with them.
Cannot activate network device eth0!"device eth0 does not seem to be present, delaying initialization".i cannot find my network card while i set up network configuration Now I use dual boot window 7 and fedora 9,I cannot find my network card in select network adapter while network configuration ,i have a network card Atheros AR8132 PCI-E fast Ethernet controller NDIS(620)and for wired in Accer laptop .
I am fairly new to ubuntu server, I want to setup a tftp server to mount a new kernel in a DaVinci platform. I was following the guide in this page [URL]..docs/linux_tftp, but accidentally I remove the xinetd.conf file. So I think that maybe removing and reinstalling xinetd the problem will be solved, but instead of that I can't completely remove xinetd and the follow message is print in the terminal
Removing xinetd ... invoke-rc.d: unknown initscript, /etc/init.d/xinetd not found. dpkg: error processing xinetd (--remove): subprocess installed pre-removal script returned error exit status 100 invoke-rc.d: unknown initscript, /etc/init.d/xinetd not found. dpkg: error while cleaning up: subprocess installed post-installation script returned error exit status 100 Errors were encountered while processing: xinetd E: Sub-process /usr/bin/dpkg returned an error code (1)
with that problem I can't start the service or stop it, I am blocked in the configuration of tftp server.
When I try to pxe boot a Sun X4100 (which actually has a RHEL OS on it right now) I get the message TFTP open timeout. All traffic is allowed for port 69 udp in both directions. I do get a dhcp address. I see that both on the server and the client it gets an IP. After that I get this message in the logs:
Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled. Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw (192.168.1.1) to the eth0 device and the network is useless.
I can't get wake up on lan (wol) to work on my network card.The strange thing is that before I had it working with the exact same hardware. But I was on Centos 5.4 then. Now I am on Centos 5.5.Am I correct in concluding that the sky2 driver does not support wake up on lan?
I'm trying to activate a wireless network on an ubuntu server 10.04. The machine has a TPLink PCI wireless card. Card is well recognized, and scanning for wireless connection it finds correctly the essid of the access point in the room. But when I try:
Code: $ sudo iwconfig wlan0 essid "apoint" key s:my_key_8 this error is returned: Code: Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.I looked for similar situations over many forums, and I found that it could be the card doesn't support the encryption type (My AP uses WPA with TKIP). However if I use an ubuntu desktop live CD on the same machine, I can connect witouth any problem with NetworkManager 0.8.
I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
The problem is that the above resolv.conf file doesnt work anymore. The only way that our workstations get name resolution is by commenting out the second and forth lines, which happen to be our secondary DNS. This has got me confused because why would resolv.conf be broken by having a secondary nameserver and search path? Shouldnt it just use the first nameserver unless it fails to resolve? Almost seems like just having the secondary in the file breaks name resolution. I cant ping local hosts or anything on the internet unless I do this:
Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 213.8.155.67. The other IP (213.8.155.42) works without any problem.How would I go about troubleshooting this?
ifconfig: eth0 Link encap:Ethernet HWaddr 00:26:B9:44:11:3A inet addr:213.8.155.33 Bcast:213.8.155.127 Mask:255.255.255.128 inet6 addr: fe80::226:b9ff:fe44:113a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I would like to have ftp access the files on a Linux Server using XP. It's easy with a windows server but Microsoft doesn't work with the Linux server.
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 trying to access data from TFTP server which is running on my fedora 15, when i tried to read that file from TFTP path..i'm getting response as time out.. even i tried to get the data in localhost itself...there also i'm getting same time out.. i tried all permission mode.
how to setup a home network for learning purpose. i have two laptops and a desktop connected to a modem-router for broadband (wired connection), i want to setup one as server and the others as client.
I am looking for a gigabit network card for my centos 5.4 server. I am looking for something known to work well with linux. I have been on the bestbuy site and I found a DLink (DGE-530T) card with support for linux from the vendor but after reading feedback from users with that card I am not so sure it is linux friendly. I am now thinking of buying online.
I'm setting up an LTSP server using Ubuntu 10.4 64bit, and PXE connecting with thin clients using Atheros cards. The ltsp environment is 32bit.
Unfortunately I get an error message with "No interfaces found! Aborting..." and a kernel panic early during PXE boot.
After an enormous amount of investigation, I've narrowed it down to (probably) being the fact that the ltsp chroot environment doesn't have the correct driver for my network card (I believe it's atl1c). The correct driver IS available in Ubuntu, though, as I can successfully boot the thin client from both 64bit and 32bit live CDs and bring up the network interface.
how can I install the correct driver in the PXE environment?
My name is Matt i've installed Redhat software on my PC using PCI network card.which command can i use to setup my PCI card to be the default network card?
I am trying to set up an internet only Wi-Fi station using Ubuntu 10.04 so I can get on the internet while my wife does her school homework online. I was wondering if there is a driver for the ZyXEL G-302 H/W v-2 wireless card available? I have checked several sites and can only find v3 drivers.
I have an ubuntu 8.04 dedicated server running openssh which I am having problems with.
The server is based in England yet I am currently working from Thailand. Slow speeds and timeouts I am used to but it is now over 24hr since I have managed to SSH the server (from here).
I just tried remote desktop on my PC back in the UK and this connected straight away through both SSH and SCP.
Thinking that it may be the IP being blocked from my works network I switched off wifi on my phone and tried to connect over the data network a few times with no luck.
Another strange problem is that when we got the server it was locked into a chroot jail which SSH(22) always leads into. After accessing SSH on port 22 I have to run a break script to gain root access. The sshd_config file says that the server is listening on port 57 yet I have never been able to access this.
I booted ubuntu and the included drivers worked beautifully for my Atheros AR8131 PCI Ethernet card on my laptop. I have an OSX Snow Leopard dual boot setup and my Ethernet card does not work. I was wondering if, because OSX is loosely linux based, the network drivers could somehow be loaded into my Snow Leopard install.
I'm running Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.
Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?
