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:
[Code]....
Using Fedora 14 as a TFTP server. I am neither able to get nor put files on the this server. The error I get is "Timeout occurred." Here is /etc/xinetd.d/tftp:
service tftp
{
disable = no
socket_type = dgram
[Code]....
I have verified the files are in the directory. I have given read/write/execute access for everyone on /home/cisco/ms-sol. On Fedora I have disabled iptables and selinux. On the client (windows xp machine) I also disabled the firewall.
When doing put, for example, I took wireshark capture from the windows PC and I see several "read requests" before connection times out.
Since I upgrade our cluster from the FC14 to the FC15 I have a bad problem with the tftpd server. I have some thinstations booting over the network after the update the boot failed with the message "TFTP open timeout". I use an "ip alias" (cluster adress) for the tftp server (next-server in the dhcp), when I use the real ip I have no problem. I found some information about a "Service Guard environment" and an option to enable it:
"This option is required for some tftp clients. These clients reject the tftp reply received from a different IP address than the one requested when the server?s interface is configured with an alias IP address." I do not see an option like that in the tftpd server of the FC15.
In Jaunty (9.04) I've setup a small (eleven-terminal) ltsp network at the local school. It handled around 6600 working hours with ease.
Now I've upgrade the server to Karmic Koala (9.10) and it just stopped working.
1) The clients have PXE NICs
2) They get the proper IPs from the DHCP server and respond appropriately to changes in the DHCP configuration files.
3) DHCP server also points the clients to
filename=/ltsp/i386/pxelinux.0
4) When the clients try to download the pxelinux.0 over tftp they just timeout
5) /etc/inetd.conf has an entry like
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
6) The file /var/lib/tftpboot/ltsp/i386/pxelinux.0 exists on the server
I'm lost at all these configuration files and protocols.
I have a problem installing CentOS 5.5 over lan. I set up a dhcp3 server and it works, client got an ip. I set up a tftpd-hpa server and it works, client can boot the install image of CentOS 5.5 I set up an apache server and it seems to be impossible... In the installation marathon I clicked through the menu to the choice of the web server where my installation files are available. I enter the ip 192.168.138.1 and the path CentOS-5.5 and CentOS tells me "Unable to retrieve http://192.168.138.1//CentOS-5.5/images/stage2.img" . Thats right because the two slashes are not right. Where the hell come the two slashes from???
I edited my httpd.conf like this:
<Directory /tftpboot/CentOS-5.5>
Options Indexes
AllowOverride None
</Directory>

This is very old topic but despite of trying out all possible solutions available on net and forums, I am not able to setup tftp server on my 2.6.32.11-99.FC12.i686.PAE. Is there something obvious missing out.

I am trying to setup a TFTP server and followed these instructions in setting up TFTP-HPA.
[URL]
I pretty much followed every step but commented out these two lines from the /etc/xinet.d/tftp.
# only_from = 172.31.0.240/28
# interface = 172.31.0.252
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
Can i set tftp server on RHEL 5.5 for Fedora Kickstart?

I'm trying to setup a network boot server and I'm having an issue with tftp. In the /etc/xinetd.d/tftp file, I added the "-v" (verbose) option to the server arg line so that i could figure out what was happening. When i looked at the /var/log/messages log file, it let me know that permission was denied to /tftpboot/nbi_img.
So, in short, my problem is that tftp isn't working because it doesn't have permission to /tftpboot/nbi_img. I can't figure out why. I stumbled upon a site where the user figured out a temporary fix to this issue and what he did was disabled the xinetd service and typed the following command:/usr/sbin/in.tftpd -l -v -v -s /tftpboot/nbi_imgWhen I do this as well, it works! but only until I restart and then I have to do that again. Is there a way to be able to fix that for good?
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

So I'm playing around w/ some Cisco equipment and needed a quick tftp server. Go to command line and type yum install tftp-server. I get No Package available! I can clearly see it here on the i386 repo. Any ideas?? In the meantime, I'm just going to upgrade this lil 600m laptop to CentOS 6 to quickly solve the problem but I thought it was curious.
View 4 Replies View RelatedI have tftp-server running on Centos 5. Clients which are on the same subnet as the server are able to get and put without problems. I have a client that is across the internet that is having trouble getting files from my tftp server. A tcpdump reveals that the client is requesting the same file over and over again. In /var/log/messages, I am see the following error repeated over and over until the client finally gives up.

View 1 Replies View RelatedI am trying to wade through the semanage jungle to get permissions for a tftp client. I followed the HowTos [URL] but I get the following at the client:
tftp> status
Connected to 192.168.1.101.

Rexmt-interval: 5 seconds, Max-timeout: 25 seconds

I finally figured out that the firewall directives shown at the end of the HowTo refer to semanage although the options are stated incorrectly according to the man page for semanage. I did insure that the file hello.o4 in /tftpboot has read permission for everybody.

I'm trying to TFTP router configurations to a server in the same local network without having to first make files in the server's TFTP directory . The transfer of a config file from router to server works perfectly if I make a file with touch and then chmod the file with 777. I found information that says to use the -c or --create option in the TFTP configuration file (/etc/default/tftpd-hpa) if you want TFTP to work without having to create the files first. The problem is, I have set this parameter and restarted TFTP , but it is not working.
Here is my /etc/default/tftpd-hpa file:
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
#TFTP_DIRECTORY="/var/lib/tftpboot"

Could not find how to change the post <prefix> I remembered clearly I did before.
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.
I'm looking for a purely standalone TFTP server that does not make use of inetd, can be run by non-root users (at non-root port numbers, of course), and if run as root, can do chroot and switch to a non-root user to shed root privileges.
