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.

I set up my first web server and it works flawlessly -when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.
I have two network interfaces on my server, eth0 (public static IP connected to internet directly) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1. It is connected directly to the internet and serves as a SNAT for other comps on the lan.I added "192.168.1.1 www_server_com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.HOwever, the server itself only opens website if the address islhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www_server_com ( I cant use dots as I do not have more than 15 posts on the forum )Here is the firewall script I am using.

A while back I've been playing with the idea of setting up one of my machines as some sort of data server and would like to access it through SSH. I've already conducted some tests through the wireless router and apparently on the software side there are no issues with the SSH thing. I also noticed that since the same adapter was in use (wireless) SSH 'fought' with the Internet for the bandwidth
In order to avoid the aforementioned problem and also in the spirit of enhancing security I am thinking of setting up the following network scheme with two laptops and two routers (a wired and a wireless one):Both laptops would receive the Internet service through the wireless router. Both laptops would be connected through their Ethernet ports to the other router. The wired router wouldn't be connected to the Internet. Would this set up allow me to use SSH only through Ethernet thus eliminating possible bottlenecks in the wireless network? I am operating in the assumption each machine would have two different IPs (one per router), is this correct?
For some weird reason (default network device?) when I connect the Ethernet cable to the laptop, although NetworkManager claims to be still connected to the wireless network, I can not connect to Internet (the wired router has no Internet BTW). But if I unplug the Ethernet cable the Internet continues through the wireless network.
In the past, I've installed Internet services as daemons and as xinetd.d with no problems. Those approaches do not meet my needs. And, perhaps, nothing will.
- the service was converted from VB-6 to wxPython. It has a GUI which is accessed with either "remote desktop" or VNC.
- the wxPython service works on Windows and can be accessed from other hosts on my LAN
- the wxPython service works on CentOS and Fedora, but can only be accessed from within the server host. Even from other user-ids. But, I cannot get to it from other hosts.
- ipchains AKA firewall ports are marked for INPUT.
- The server host uses autologin to fire up a useid in group "user". I do not want it running as "root". the .bash_profile fires the service up.
- the service is heavily mult-threaded, and supports devices connected to serial ports asynchronously with the ephemeral port threads (all this works).
There are some programming solutions that I would rather not develop.
- a proxy service that runs under xinetd.d.
- separate the GUI code from the Internet and serial port code. Allocate a "control" port for remote GUI control. a'la SAMBA & SWAT
Is there any hope, that I can run it as is, by doing some network configuration stuff.
I am a newbie to linux of 4 weeks. I set up my first web server and it works flawlessly - when accessed from external network or from other computers on my lan.

HOwever, the server itself only opens website if the address is localhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www.server.com.I do not understand why the record in etc/hosts doesn't point it in the right direction. It seems that when I open address 192.168.1.1 it still gets routed to the external network. I have seen using DNAT to deal with the problem but it didn't work in my case (maybe I didn't do it correctly). I have spent whole evening/night trying to sort it out, it's 4AM now, going to bed frustrated and angry (at myself hahaha). Still like linux very much, won't be going to windows anymore. Please help
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

Before the other day, I'd copied a live CD to ramdisk and run it from there before, but the disk was INX (INX is not X), a live CD based on Ubuntu that runs entirely in the text mode, no GUI. INX is a terrific product: colorful, educational, light, agile, fun to use, and and often damned useful, but when an OS only uses text, you may not notice how much running from the RAM speeds up an OS. Previously, I'd assumed that the best reason to run a Live CD from the RAM was to free up the CD ROM drive. When I started running a full KDE 3.5.10 Desktop from the RAM, it didn't take me long to notice the awesome boost in speed and performance.
The computer has the fastest access to the data that's in the RAM. (The "A" in "RAM" stands for "access", right?) So the machine is faster. As the RAM gets larger, I'm sure more and more live CDs are going to offer the RAMdisk option. Right now both INX and SLAX share the characteristic of being exceptionally small CDs, and that makes them well suited for this kind of application. The "minimal" version of Slax, the basic CD without any modules added, is less than 200 mbs, which fits very nicely on my 1024MB RAM. I now use the minimal SLAX cd to initiate the system, and I keep a collection of the modules on my hard drive to copy to the RAM and activate at will.
Here's a couple of screenshots: [URL] I'm using Wine here to run my one and only favorite Windows program, a text to speech program called READ PLEASE. Note that I am also running KTorrent, which is uploading from and downloading to my external MyBook hard drive. [URL]. Here's a shot of yakuake, which is sort of like Konsole with superpowers. I just upgraded my hard drive KDE system to 4.2.3, and they still haven't fixed Yakuake yet. I know it's been reported, so I'm sure it'll be taken care of.
Can i set tftp server on RHEL 5.5 for Fedora Kickstart?
View 1 Replies View RelatedI'm about to have a web server at home for the first time. I've always missed having full control and not having to contact my hosting company when I need to do some specific changes - and some changes they won't do for you at all.I've chosen the non-GUI Ubuntu Server with LAMP, and nothing more is installed really except for a couple of command line tools from the repository. The LAMP software has been locked down as good as I can by following some guides on the net and using common sense. Like Apache 2 don't have access to the file system except for the www folder, and setting the headers to Prod. MySQL has skip-networking and I've commented out the listen string to localhost. PHP has a truckload of functions that I've disabled in the php.ini, also by following some guides on the net, among some other security enhancing php.ini editing.
The only thing the server will serve is a well known PHP forum and some html docs, and that's all. Nothing advanced or complicated stuff, and I'm definitely not programming PHP myself or letting anyone do it for me.But I do want to sleep well at night knowing that my server is always on and sitting on the edge of my home network! And can I do that? I've heard that you don't need to be worried about getting your Linux server box hacked, but you should be worried about anyone getting root access to it. But is it really that simple? Ubuntu is shipped without root account and you must have the sudo password, right? What's the odds for anyone to get full access to my system?An issue: I've heard that Apache never must run as root. When I do a ps -ef, I see that there are several www-data processes running apache, but there's one root process running apache too. Is this normal and is it safe?An issue: I've heard that PHP can fail pretty easily. But isn't PHP running under apache 2 and limited by the www-data filesystem access?An issue: MySQL is running as a MySQL user, and I guess that's an unprivileged user right?
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.
Code:
tftp your_pc_ip_address
a machine with 2+ network cards, need to setup TFTP server on one card and use internet on another.
the tftpd server works on default routing network adaptor with following configuration.
How set the TFTP server on the secondary network adaptor?

I am at a loss. I can not access my work remote desktop via the terminal server client on my wired box running Ubuntu 10.10. My wireless laptop is able to connect right away once I established the VPN connection. The VPN connection is established on both boxes with no problems.
When I tried the Terminal Server Client on my wired boxed, it says it can not establish a connection. Yet my wireless box gets connected immediately!
I check the /etc/dhcp3/dhclient.conf and the /etc/resolv.conf to see if there were any differences, but they are essentially the same. When I have the vpnc connection, they both recognize it and I am able to ping the IP address shown when I do a "ifconfig" on the terminal.
What can be the problem? Anything I need to configure on a wired computer versus a wireless one? What else can I check?

View 1 Replies View Related*Solved* I have been reading the following guide on how to use the VNC programs and a GUI to connect to my main machine from my laptop via my LAN and router:
[URL]
This allows me to control the server remotely, and run applications on the server remotely, with the GUI output being shown on my laptop, which is really neat I had Eclipse + PDT running on my server and had to stop it and start a new instance remotely from the laptop via VNC viewer, as Eclipse said the workspace I wanted to use was already in use.
So starting the VNC server on the main machine does not allow me to access the programs that are already running on the main machine under the native X server. However I can now do PHP debugging remotely using Eclipse + PDT now, and all the PHP source code is on the server machine. That's OK, but I would like to do more than that. I want to be able to connect to the native X server on my main machine, and control all the applications running on the main machine remotely from my laptop, without having to shut them down and restart them again via a VNC viewer.
Is there some sort of remote control program I can use to allow me to connect to the running X server on my main machine from my laptop, and control those applications remotely please, so the desktop layout on the main machine's screen is mirrored on the laptop screen?

Here is how I call WinPe from my default file

A friend of mine is building a data acquisition system for a vehicle that will wander through city streets and roads and perhaps even off-road places. At the end of the day, back at the garage, the data must be downloaded and, if needed, upload an update of the data acquisition program. The network is wpa_supplicant, and it was chosen an USB device, because the original computer did not had any wireless interface and do not have any other possibility. The problem is that, when the vehicle comes back, very often there is no access to the on-board computer, or the connection lasts just a few minutes.
The computer must be reinitialized so the connection is back and the scripts run completely. Sometimes the connection is made, but the guys are so used to restart the computer that they do it anyhow, and then the connection does not come up, they have to restart it again.I have being thinking, as the vehicle drives all around, perhaps finding some access points along the day, if this connection trials - and failures - are messing up something. Or, the connection instability as the vehicle approaches the garage, could be driving his scripts mad?

in my network, users has total access to their PCs, so theres a problem to filter (URL, ports,etc.) their virtual machines installed (they can assign self any IP, e.g.)
Id thought about use the MAC prefix in VMware VMs (00:0c:29:*), but i can only found a way through DHCP, and this isn't a good solution (they can assign a static IP to workaround...)
It will be better using firewall (iptables), but I don't found the way to add rules based in MACs with wildcards.

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:

I want a debian server running dhcp/tftp/pxe containing a tarball of a 'client' debian installation.I want a client that pxe boots, talks to the server, creates a ramdisk, untars the 'client' tarball to the ramdisk and boots into it.
