Software :: Can Tftpd Be Configured To Not Have The File Exist Before Transfer?
Jul 28, 2011
I am learning Linux and especially the scripting and server administration aspect. I recently installed TFTPD on a Debian Lenny box and was satisfied with the results. The only drawback that I could find was that a file had to exist before TFTPD would allow a transfer. I understand that this is standard practice however I was wondering if there was a way around this. I am using this TFTP server to backup configurations and IOS images on our Cisco devices in a private network. If there isn't anyway to do this is there a different TFTP server that I could install that would support this functionality. I have read the man pages without much luck and doing Google searches hasn't yielded many results. I really appreciate your help and if there is anything you need from me please let me know./etc/inetd.conf fileQuote:
#:BOOT: TFTP service is provided primarily for booting. Most sites
# run this only on machines acting as "boot servers."
tftp dgram udp wait root /usr/sbin/tcpd /usr/sbin/in.tftpd -s

I just noticed that I'm downloading about 60KB/s but no connection is established according to "netstat -tup". I use fluxbox, no automatic updates and the transfer exist even after relogging of my user.

Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished. From another after copy progress closed I right clicked PSP and unmounted it..
It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched. Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished.

I want to create a logon script (or somesuch) that creates a file (if it doesn't already exist) and checks the file for some info otherwise. If it finds a given trigger in that file, it logs into a local database and does some operations.
Now my problem isn't with creating that file or even getting it to function as a logon script -- it's with permissions. After the logon script creates the file, I want that user to have read access on it ONLY. Further, I don't want to give the user any kind of root access so that they could do the database operations in question or chown/chmod the file.
What's the best practice here? I'm noticing that whenever the script runs (in .bashrc right now) the script runs with the current user's permissions. Ideally, I'd like to make it so the login script can run at a higher level of permissions, (higher than the user has). Is this even possible? What's the best way to do this?

I have to perform a bonding in few of the redhat linux servers. This is the set of files I created in /etc/sysconfig/network-scripts
ifcfg-bond0
DEVICE=bond0
BOOTPROTO=static
IP=XXXX
NETMASK=XXXXX
[Code].....
Those two are showing still configured. What is the procedure to remove them from the configured list. I don't have a x display to do it graphically.
All I want to do is rename them to different file names and remove them from the network service.

My brother is working for a company that is making various types of embedded software. He's been trying to install Micro Core Linux on a device, and it worked after some manual kernel patching & configuring. The issue is this; he need to install this system on hundreds of similar devices. Is there a way of making the configured kernel into a bzImage, so that the kernel can be compiled on the other systems without any tweaking?

What is the proper way to stop tftpd from starting up? There is no numbered rc script symlink for it so I can't use update-rc.d. I don't want to just hack a file unless that is considered "the way".

Having a problem with tftpd on CentOS 5.5. I am only able to download files from the localhost address.
I have checked iptables (by adding rules and by turning the firewall completely off -- nothing changes) and enabled tftpd logging (by adding -v to the server_args section in xinetd.d/tftp) and I DO see the request coming in, but no response from the daemon. I've also tried upping the verbosity by adding multiple -vs and/or --verbosity 10 to the mix, but all I ever see is the initial request come in, nothing more. I've even tried running the daemon in foreground mode with -L but I get no verbosity then.

I just installed Debian 5.0.4 successfully. I want to use the PC as a File Server with two Drives configured as a RAID 1 device. Everything with the RAID device works fine, the only question I have belogs to the GRUB 0.97 Booloader. I would like to be able to boot my Server even if one of the disks fail or the filesystem containing the OS becomes corrupt, so I configured only the data partitions to be a RAID 1 device, so on the second disk should be a copy of the last stable installation, similar to this guide:[URL]...

I have a problem with TFTP files greater than 32MB with Ubuntu. I haven't been able to find a fix for this issue. This has been a known issue for years and was corrected in the winodws world(AUGH !). when I did an apt-get install this morning it said my tftp was up to date.

Due to a motherboard issue, I need to edit a parameter in the "etc/default/grub" file.
However, the problem is, that file doesn't exist.
Grub does seem to be installed, I can get into grub from the command line etc.
This is a fresh install of Ubuntu Server - 10.04.2 LTS
Brand new box, no previous installs of anything, no other operating systems etc.
Is there somewhere else that file could reside ? I tried find -name '*grub*' and got plenty of files, but none are the one that I need.
Is there someway to generate this file ?
I remember when installing from the CD it asking about grub, but I don't recall which option I chose, it was whichever one was the default.
This thing won't reboot right after power loss etc until I can edit that value... which at the moment seems to not exist....
Btw, I'm not a total linux noob but far from an expert, so I may need any answers "dumbed down" a bit.
EDIT (more info):
It seems that I have regular "grub" and not "grub2" installed... I'm assuming that is part of the problem ?
My version: grub-install (GNU GRUB 0.97)
Does this version of grub allow you to edit options etc ?
Specifically, what I need to do, is edit this value: GRUB_CMDLINE_LINUX_DEFAULT
I need to add "reboot=a" to this line.

I am running a fairly new Debain Jessie stable installation with Xfce desktop. I need to use Xfce4 becuas the standard Gnome 3 does ot work when logging in with xrdp which I use becuase the actual box is headless.
I have an issue when starting synaptic. When I start it from the menu entry it just does not start. When I start from the terminal with
Code: Select allgksudo synaptic
I get an error box "Unable to copy the user's Xauthorization file" At the same time I can see in the terminal window a message
"Error copying '/home/userxxx/.Xauthority' to /'tmp/libgksu-SwcIe0': File or Directory not found".
I assume it is related to that I use a rdp session to connect, but I am otherwise clueless.
Code: Select alluserxxx@server2>xauth
xauth: file /home/userxxx/.Xauthority does not exist

I'm getting openbox up and running on squeeze. I performed a netinstall and did a simple apt-get openboxI need to modify a file called ~/.xinitrc, but it does not exist. I read that I can copy one over from /var/x11r6/lib/xinitrc, but the /x11r6/ directory doesn't exist either. I've installed xorg, but the directory still eludes me. A package search yields nothing useful. I am using the SLiM display/login manager, which I believe calls startx, which should theoretically generate the ~/.xinitrc file.
