Networking :: PXE-E53: No Boot Filename Received
Feb 10, 2010
I set up environment according to BareMetalProvisioningBestPractices document, I think everything should be ok. Now trying to plug in new virtual machine for PXE install Linux. But something is wrong, DHCP waits couple of seconds, and then I receive:
PXE-E53: No boot filename received
PXE-M0F: Exiting Intel PXE ROM.
I think, all services required are started.
dhcp.conf on boot/stage is:
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
[Code].....
pxelinux.0 was taken from RHEL4, but I've got image and trying to boot RHEL5. Maybe there is something?

i had a working multi-boot system, vista on sda1,2; swap sda3; ext=sda4; ubuntu sda5; fedora sda6; data sda7 - i mount the data partition when using all of the linux releases so i don't have to have multiple copies of music, docs, etc. everything has worked fine until yesterday. i tried to install fc12 on sda6, replacing fc11. it required me to format sda6 as ext4. i wasn't sure where i had grub installed, but have a backup of menu.lst in data (sda7), so figured i could let it install to mbr or wherever it wanted to by default. when the install completed and i reboot, i get a black screen and these messages: CLIENT MAC ADDR: 00 19 XX XX XX GUID: XXXXX PXE-E53:
No boot filename received
PXE-M0F: Exiting Intel Boot Agent.
No bootable device -- insert boot disk and press any key I tried reinstalling fc12, same exact errors. I then thought maybe the problem had something to do with ext4 partition mixed in with ext3's, so i installed mepis on the sda6, and let it write grub to mbr (i think, not really sure where it wrote it). anyway, i still get the identical black screen. no grub type menu or anything. the screen used to show "DHCP for a few seconds", but doesn't anymore after i disconnected the ethernet cable.........

$ uname -a
Linux a 2.6.35.10-74.fc14.i686.PAE #1 SMP Thu Dec 23 16:10:47 UTC 2010 i686 i686 i386 GNU/Linux
$ lsb_release -a
LSB Version: :core-4.0-ia32:core-4.0-noarch

How can I set a pattern that will output a filename equal to the original filename? E.g.
something.mp3 → something.ogg
And why isn't this implemented in SoundConverter?
PS: {Filename} doesn't work.

I need to split a filename into its filename and extension, so I can append a datestamp to the filename. I'm using bash.

I've installed ethernet adapter, it is made in china from a manufacturer called FOX. The driver for that adapter is supported for sco linux kernel version 2.4.x and 2.5.x .However, I'm using Centos5 but the OS didn't recognize the adapter alone, so I'm trying to follo instructions on the driver on the attached CD.
The CD contains file named "SC92031.c", the instructions tell me to do the following "Compile the driver source files and it will generate sc92031.o"

I have a relatively new computer that won't boot Win 7. After going through a lot of tries, I got a suggestion that I try to boot using Ubuntu from a USB flash drive ( since I can't burn a CD).
I followed the procedure to put the necessary files (Version 10.04 64 bit if I recall correctly) on the drive and tried to boot using it.
I got this message:
When I tried to boot again (from the above) I just got the second message (No DEFAULT etc.)

How can we convert a dynamic library (filename.so) to a static library (filename.a) using gnu gcc . Can we get a static library form a dynamic library . I saw a few post in which the conversion form a static library to a dynamic library is mentioned but, unfortunately, not the other way.

I am new to Ubuntu almost installed it after windows showed blue screen 4 ever n ever. However after installing ubuntu whenever I log in windows it doesnt detect any network connection but when I use Ubuntu it automatically does can it be that Ubuntu is causing any problem? And how to check how many packets are being sent and received through my wired network and do I have to install any drivers for my modem in Ubuntu.

This has been bugging me for quite a long time. I need to have a pptp connection to my university. I have tried to locate the error, but this has been a real trouble.
A little bit of history: My girlfriend had a laptop with M$ vista on it with a working PPTP connection. I had a laptop with Ubuntu, with which I couldn't get the PPTP working.
When my laptop crashed, I bought a new one on which I run a dual boot XP SP3 and Ubuntu. I also own a desktop (Dual M$ Win 7 / Ubuntu standard Karmic) and my girfriend also upgraded to Win 7.
Currently, the XP version is the only one on which I can get a connection. Both Ubuntu and the Win 7's give me a GRE proc 47 not received error. I know our router (a DAVOLINK DV2020) is notorious for not sending through GRE proc 47, but this either shouldn't be the case or it shouldn't matter, since I can make a perfect connection through the XP OS.
This is quite a handicap, since we both study at the university for which we require working VPN PPTP connections.
Settings:
Gateway: vpn-eur-pptp.eur.nl
Username: 123456ab@eur.nl
Password: password
Authentication: MSCHAP / MSCHAPv2

I was wondering if there was a Windows or Ubuntu way to limit the amount of data that is able to be sent over the internet between certain times, eg. Between the times of 7am and 7pm can only download 300 MB from the web, when this limit is reached the web is either disconnected or slowed down.

I am having (seemingly) random trouble with my wired network ever since I installed Lucid. I have no problem getting an ip address from dhcp. However, randomly the computer will boot and although I have an ip address I do not receive any responses for pings on the network nor can I browse the web. If I sudo /etc/init.d/networking restart a few times (or reboot) it will start working. However, restarting the networking services (as mentioned above) again will cause me to no longer receive responses for pings or browse the web.
Furthermore, I have never been able to successfully ping if I manually set an ip address. I have un-installed network manager and I am using /etc/network/interfaces to configure the network. Using Lucid Lynx 64bit on a Dell Precision. I have pasted below the output of a few working commands. When I switch between static ip and dhcp I am commenting/uncommenting the lines shown in /etc/network/interfaces.

where packets are stored when they're received. After some googling, I think perhaps libpcap with mmap would be the solution. Does libpcap 1.0 and above support mmap?From my understanding, mmap would allow me to directly access the buffer without having to explicitly copy the packet to another buffer for me to do processing. I would also appreciate it if someone can let me know where I can find examples of such applications, as many examples of mmap I've found involves mapping a buffer for file operations, rather than integrating it with pcap functions like pcap_loop, pcap_next_ex etc.

I have a Webserver (Co-Location) and all runs fine ... since last week. Now there are a lot of RX-ERR shown in netstat and ifconfig. And when I try to upload a external website direct on the server for example via wget, it is very very slow and hangs very often.
RX packets:2919694 errors:990386 dropped:0 overruns:0 frame:596420
TX packets:4231423 errors:0 dropped:0 overruns:0 carrier:0
I have analyse the network but I was not able to find a problem. My hoster has checked the network and all looks fine. For example my hoster has plugged-in a pc in the same switch ... and was able to do wget (load external data, like websites) in normal speed.
Since last week my websites were delivered slower as before, too. It seemed there is a network-problem ... but how can I find it?
Actually I can install moduls ... but the server needs hours. So, if you knows a good command-line tool to analyse the network.

I'm trying to mount a windows share (that mac users use) using:mount -t cifs //x.x.x.x/Graphics /mnt/graphics -o username=x,password=x,iocharset=utf8.It mounts ok for the most part, but where the mac users put bullets in front of their file names, ubuntu displays questions marks. I've tried this without the iocharset as well and same result when I execute ll -l.

I used to connect to the internet via a Linksys router using the following terminal commands (Network Manager has never worked for me on any Ubuntu install):
Code:
sudo ifconfig wlan0 down
sudo dhclient -r wlan0
sudo ifconfig wlan0 up
[code]....
However, I recently changed the old modem + router for a new wireless modem (a Thomson TG585v8 ). Now, the result of that last command is this:
Code:
amosupremo@amosupremo:~$ sudo dhclient wlan0
Internet Systems Consortium DHCP Client V3.1.3
[code]....
No working leases in persistent database-sleeping. I've tried to connect in Natty(both Ubuntu and Kubuntu) and it's not working either.I also purged Network Manager and installed wicd and I managed to get an intermittent, slow connection.
1 ) Machine Brand and Model (PC/Laptop): No brand. I built it with the following specs:
AMD Athlon II X4 2.6GHz
2 HD: 100GB Sata (Ubuntu and XP64 install) / 80GB IDE (XP)
4GB RAM
Gigabyte Motherboard
2 ) Wireless Brand, Model and Wireless Chipset:
Code:
amosupremo@amosupremo:~$ lsusb
Bus 002 Device 005: ID 0ace:1201 ZyDAS 802.11b
Bus 002 Device 004: ID 049f:000e Compaq Computer Corp. Internet Keyboard
[code]....
3 ) check interface:
Code:
amosupremo@amosupremo:~$ ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:02:72:04:d0:04
[code]...
I am also attaching the wicd log. It contains a session where I got the intermittent connection. I stopped that connection and restarted it (with the same results) two times.

The task I am trying to complete is the virtualization of an IPv6 router created using two fedora machines. Here is the physical setup I have now...
PC1:eth0 <------> network
PC1:eth1 <------> PC2:eth0
PC1:eth2 <------> PC2:eth1
PC1 runs radvd to provide router advertisements to the network and a DHCPv6 server for stateful addresses.Each interface is configured on a separate subnet. PC2 runs a DNS server on eth0. PC2:eth1 is used as an IPv6 client for testing purposes. The connections from PC1 to PC2 are just crossover cables.I've created virtual machines of both PCs and have created 4 virtual adapters on the host machine for each of the local-only interfaces.Now I have this:
PC1:eth0 = HOST eth0
PC1:eth1 = HOST vboxnet0
PC1:eth2 = HOST vboxnet1
[code]....

I have a Sony Vaio PCG-5A1N (built for Japan) which has a malfunctioning CD-ROM. The bios doesn't support USB external CD-Drives and it doesn't have any USB boot either.The only method, I am left to work with is the PXE boot. I have finally setup a PXEBOOT on another CentOS server and everything works fine all the way to choosing language etc....but after it grabs images/stage2.img this is what it gives me:
loader received SIGSEGV! Backtrace:
[0x8048cf4]
[0x300420][code]...

i want to resolve the above error. I'm using systemimager to autoinstall system images on pc's connected in lan. while doing this i got the error No DHCPOFFERS received. Also at the time of booting my pc it shows the message No dhcp and/or proxyDHCP offers recieved. But i've started the dhcpd deamon on my pc. Also the systemimager rsync deamon is running. The two pc's are also connected in lan properly.
Still while autoinstalling the image on client it fails showing the error message... No DHCPOFFERS recieved. what do i do in order to make my autoinstall work properly? How do i come to know whether the dhcp server is running or not? What will be the exact problem in autoinstalling?
