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.
View 3 RepliesWhen 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:

I 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.

I have been trying to accomplish this feat for about a week now, and I always seem to get a boot up error.
Here is how I call WinPe from my default file
Code:
I did a basic U9.10 server install of postfix with the minimal config. Added a test user and things worked after a few minutes. I now want to setup a few new things and want to switch to use mysql as the back-end. I have mysql installed, setup postfix.admin which in turn setup the database/tables. Now when I logged in to that admin, the original test user is not there (which is fine), but I created the test domain again, created a user and an outside test failed saying user unknown.
Now I looked through the main.cf page and don't see anything obvious to say hey, put backend is mysql, here is the info. I then noticed via apt that postfix-mysql was not installed, so installed that, I see my .cf was backed up, but still don't see anywhere to connect the 2. So currently mail is still accepted from the test1 user running local. I don't mind wiping everyhing, but is there a simple place to just make a change or 2?
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

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.

View 3 Replies View RelatedI 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?
venturing into unfamiliar territory so I'm hoping someone can help me and make things a little more understandable for me. I have setup Postfix on a standalone server connected directly to the internet. I have got inbound and outbound email working for the most part, but I am worried about security.My fear is that if I leave port 25 open to the outside world spammers will find this and start relaying mail through it and eventually blacklisting the IP attached to this box.
For now, I am hosting mail for a single domain and single user (me) with a few aliases. I plan on expanding to IMAP and SMTP access from the outside at some point, but for now I've been using Mutt in a shell and it's fine for my needs for now.
Here are my current Postfix settings:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

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 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.
Mode: netascii Verbose: off Tracing: off
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds
tftp> get hello.o4
tftp: hello.o4: Permission denied
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"
TFTP_DIRECTORY="/tftp"

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 ...

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
