Software :: Deal With An Existing WDS PXE Directory?
Jun 28, 2011
An existing Windows 2003 Server hosts a WDS pxe role. A networtk shared directory provides some customized OS.
I have to migrate this server without altered the WDS directory. Is it possible to deal with this stack under Redhat with pxelinux ?
Actually, my tests are negative. But I definitively have to deal with as a requirement. Otherwise an update will be made for each alteration of the OS.
POC : Red Hat 5 64bits, Apache2, Samba3, pxelinux, tftp-hpa.
I had successfully boot a virtual pc under Red hat. But I'm alaways game over with the corporate OS. When I load a pxeboot.n12 file there is an invalid file or corrupt error. When I rename this file as pxeboot.0 (to use pxelinue) the next step is a boot menu. I load a BCD file but after a boot.ini file is required but not present. This file doesn't exits in the current directory.

I have a directory of about 1500 tagged mp3s (the directory contains a sub-dir for each artist which contains a sub-dir for each album which contains mp3s). What I am looking for at the moment is a player that allows me to import this directory once and then allows me to navigate the mp3 by tag. I have looked at audacious and abraca but either these don't have such a feature. How to me how to achieve what I need? I use 64-bit squeeze

Today I found something really interesting (at least to me) on one of our test servers:
I can change into an existing directory from my actual working directory using a relative path, but that very same directory is not listed when using ls -a.
Here is the shell session (as root):
$ pwd
/you/are/here
$ ls -a
. .. <-- Note: "somedir" is not shown to root
$ echo $CDPATH
[Code]....
I had checked the automount thing mentioned by Gilles, but as I had changed to somewhere and issued a mount|grep somewhere there were no output.
Here is the lsattr and strace output as suggested: [URL]

i have been using linux for about 2 months now , and still can't deal with tar.gz files! i extract the achieve , open the folder , open terminal in that folder , then make and..... nothing i didn't find the make file in firefox 6 tar.gz for example , for other files there was missing libraries , is there a compiler that can do the job simply like synaptic? it is really stupid that every application should have its installation instructions!!!! why there isn't some standardization for all linux distro in this point? deb packages are simple to use , why there isn't a general package system for all linux distro ? or at least a unified system for compiling where i can use the tar.gz files like .deb files?

I have an existing unix user that some how didnt make it into the copy over to our LDAP server. How do I add an existing unix user to an existing LDAP directory? Will ldapadd work? I was under the impression ldapadd required an ldif file to work properly.

All the Ubuntu networking info I can find online talks about Samba and how to deal with a Windows/Ubuntu networks.
I have 4 computers for my family, I just installed Ubuntu (10.04 lts on 2, 10.10 & 11.04) on them. They are all dual boot with XP.
Is there a tutorial that talks about just dealing with an Ubuntu network? I would assume you don't use or need Samba if windows isn't involved?
Also it looks to me that the work-group name is more important to windows. Is it even necessary with Ubuntu?

It's starting to feel like Ubuntu 9.10 users have been left out in the cold, or at least forced to fend for themselves. I'm referring to the publicly-known vulnerabilities present in Firefox 3.5.9 (the version currently in use by Ubuntu 9.10). Ubuntu 10.04 (which uses Firefox 3.6.x instead of 3.5.x) users received their package updates June 29th, yet Ubuntu 9.10 seems to have been placed on the back burner. So basically, my questions are: Does anyone know what's going on? What's taking so long? Has security support for Firefox been terminated for Ubuntu 9.10?
PS: I can sort of understand how Ubuntu isn't able to provide Firefox patches for Ubuntu 9.04, as it uses Firefox 3.0.x (which isn't supported upstream anymore) and the distro release is so close to EOL. But, surely Ubuntu 9.10 doesn't need to be treated the same way, given that the 3.5.x branch it uses is still supported upstream and the distro release won't reach EOL until Q2 2011.

Also happens with Gimp (when it does run it's plug-ins). Parts of Gimp started by `gimp q.jpg&' freeze and cannot continue unless "killall -CONT" or made foreground. Is it a bug? How to reliably start things in a background?

I have a strange problem regarding the connection to a LAN. I have a asus eeepc 1000H with Ubuntu netbook remix 9.10 (dual boot with WinXp). I've discovered two days ago that one of the pins from the ethernet port is pushed inside. This led to the fact that my netbook is not capable to deal with some UTP cables in the sense that it won't connect at the network through this cables. These cables work perfectly for any other computer.This is true for XP - for Ubuntu I found that it is not possible at all to connect through any cable at a LAN. There is an exception to that - my internet connection at home is done through PPPOE and I am able to access the internet through Ubuntu and WinXp.
Asus Romania won't honor the warranty (in their opinion I abused the product and it is my fault - fair enough - it is my fault since I am the single owner of the product - and I am connecting it in various locations to various ethernet cables) and in order to fix it they told me they will need to change the entire motherboard - which I guess it will cost me a price close to the price of the netbook itself - and I don't want to pay that much just for a pushed inside pin. (I wrote these to avoid questions regarding the warranty).I can live with the fact that some of the ethernet/UTP cables won't work with my netbook - but I can't live with the fact that the Ubuntu OS is not capable to connect to the internet through the ethernet port in any other locations besides my home. I require help in order to establish if there is something wrong with the Ubuntu ethernet settings or the Ubuntu OS is not capable to connect to internet through the faulty ethernet port (WinXp can).

we've been trying to become a bit more serious about backup. It seems the better way to do MySQL backup is to use the binlog. However, that binlog is huge! We seem to produce something like 10Gb per month. I'd like to copy the backup to somewhere off the server as I don't feel like there is much to be gained by just copying it to somewhere else on the server. I recently made a full backup which after compression amounted to 2.5Gb and took me 6.5 hours to copy to my own computer ... So that solution doesn't seem practical for the binlog backup.Should we rent another server somewhere? Is it possible to find a server like that really cheap? Or is there some other solution? What are other people's MySQL backup practices?

For about a week now I've been seeing mass attempts to relay through postfix and login to dovecot from the same 2 addresses, none are successful due to how postfix/dovecot are configured and I wouldn't be overly worried but my isp have picked up on it and are nagging at me
What ways do people go about just dropping connection attempts from offending addresses/ranges when stuff like that happens? An ideal thing would be something that detects repeated failed attempts from a host or range and subsequently ignore/ban them, perhaps for a specified length of time, something along the lines of denyhosts and fail2ban for ssh would be great Don't know if there's anything out there or just a plain tried and trusted method anyone might use for stuff like this, if not a hint on the most appropriate way to go about it 'manually' would do

Just wanted to share a script that I wrote to migrate data off of a Time Machine backup. As anyone who's tried this knows, it's not straightforward because most directories are pseudo-hardlinked according to some hare-brained scheme Apple came up with. (Hard-linked directories actually show up as zero-length regular files with bizarre link counts greater than 128. The link count corresponds to a directory called "dir_$N" (where $N is the link count) inside of a special directory at the root of the Time Machine volume called ".HFS+ Private Directory Data^M" (where the ^M is a literal carriage-return character).)
Here's the script (it's also attached, for convenience). It works pretty much the same as "rsync -av <SRC_DIR> <DST_DIR>" would, if the pseudo-hardlinks weren't in the way. In other words, it just recursively copies the first directory to the second. So the first argument (the source directory) is typically something like
/media/<TIME_MACHINE_VOLNAME>/Backups.backupdb/<HOSTNAME>/Latest/<VOLNAME>
if you want the entire latest backup. It can also be a relative path, if you've already changed to a directory inside the backup.

I've been having terrible trouble with my 64bit Desktop v10.04 ever since I upgraded it. Has been a long battle - but I think I have it down to just one remaining issue which I suspect is more related to the network than to the upgrade. So I'll ask here also... The old system always used grub as the bootloader, and has always worked just fine. I have now had to do a complete fresh install, which incorporated a change to grub2 (first time I have used it).
It would seem now, that grub2 is unable to deal with mounting the samba shares on my lan at boot time. The boot always fails, dumping the user to the cli rather than the gui desktop. The error given indicates that the network is unreachable. Most users of the system have given up on Ubuntu altogether because of this, and fallen back into the clutches of the evil empire (the machine dual boots XP). If I log in, and manually startx to open the desktop, the network is there, and the shares are mounted just fine. Everything seems to be working ok - but for crashing out of the boot process with network errors. The fstab file follows, in case there is some cause there I'm not seeing (I have edited names and passwords prior to posting)...

I have a server with Fedora 13 with which I would like to get NFS working. I have looked up multiple howto's and tutorials, but I'm having a problem not addressed by any of them.Official how-to, another how-to, and another how-to.I have verified that nfs-utils, nfs-utils-lib, portmap, and system-config-nfs are installed and running. I have verified that I have, in fact, shared the directory that I want to share, and that the proper permissions are set.
I had to go through some gyrations to get the Belkin wireless N router to allow my server to have a static IP. However, I can ping the server from the nfs client (a toshiba satellite running mint 8), and vice versa. I have (for now) disabled firewalls on both computers. I think I have disabled SELinux on Fedora 13 (for now).When I attempt to connect to the server from the client, the output looks like this:Quote:
aragorn ~ # mount -v 192.168.2.101:/test /home/kelev/test/
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Sat Dec 18 12:21:09 2010

I've done a low level format on them so they're completely empty. When I use them with my windows machines, they're absolutely fine. When I plug them into my Ubuntu machine, there is a hidden directory created called 'RECYCLER' which I'm assuming is for deleted files?However, it also creates a .exe file in this directory called 0x2D9FA278 which has an Icon with an H in it and a comment of 'Facebook Photo' This has the effect of making all the directories on the stick into shortcuts! I googled the file name and it seems to be some sort of Trojan, but I don't understand how it's go into my Ubuntu machine, I've scanned with ClamAV and it finds nothing.

I am a student studying computer science course.
Well, I am facing problem when doing lab questions.
I must use DLXLinux bundled in Bochs (bochs.sourceforge.net).
I am required to use the /usr/local directory.
In /usr directory, there is no directory named 'local' but there is one thing called 'local@'. So, when I try to use mkdir command to create 'local' directory in /usr , there are error "cannot make directory.....".
Look at my screenshot at [url].

Recently I mounted a larger partition into my home directory since I was running out of space, Everything went smoothly, but it caused me to wonder about something I cant figure out. While playing with the mount unmount commands when I was copying everything over... before editing my fstab.
Is there a way to access the files that existed in a directory before you mount a partition to that directory? after mount the original files are gone.unmount and they are back, Where do they go?
