Description

This is a known problem due to a bug -- tftp puts don't work at all. Corrected RPMs are available at e.g.: ftp://ftp.redhat.com/pub/redhat/beta/wolverine/en/OS/i386/RedHat/RPMS/ *** This bug has been marked as a duplicate of 18128 *** tftp-0.17-9 still doesn't fix tftp uploads My tests indicate that it's tftp client that it's broken. I grabbed tftp-0.16-5 compiled on RHL62, and uploads to 0.17-9 work fine with it. There are no compile warnings with tftp client 0.17-9 (except implicit declaration of memset, which doesn't cause this), so this is most weird. Perhaps reverting back to the beta for now might help ? *** Bug 30294 has been marked as a duplicate of this bug. *** I'm able to confirm that this is happening with 0.17-9. Get works, but put doesn't. Tim A sniffer trace shows that tftp is failing to respond with correct block number to start the transfer. The correct sequence is to ACK NR=0 . This would allow the client to begin the data transfer. The failing tftp always responds to the TFTP WRQ with ACK NR=1 and the data transfer never gets started. -- Blaine This bug should now be fixed in tftp-0.17-11, available from rawhide or directly from ftp://people.redhat.com/hdeller/ Please also check your /etc/xinetd.d/tftp to have at least the following entries: wait = yes user = root server = /usr/sbin/in.tftpd server_args = -cs /tftpboot disable = no (The -c in server_args enables the tftpd-server to create files), and that user nobody has write-permissions on /tftpboot if you want to test uploads/puts. *** Bug 36738 has been marked as a duplicate of this bug. *** Version 0.17-11 still does not work. No puts, no gets. /etc/xinetd.d/tftp is as above, /tftpboot is owned by nobody.nobody, mode 777, file /tftpboot/testing is the same, tftp will not get the testing file. Puts also don't work. I installed tftp-server-0.17-11 . Both puts and gets work for me. Check to see if your /usr/sbin/in.tftpd actually was updated. The tftp-server-0.17-11still does not work . Using redhat rpm and did not
compile code. Has anyone had any luck? Does any know if tftp compilied code
work? Below is my setup and log files. Does anyone have any suggestions? I have
verified that /usr/sbin/in.tftpd is updated.

please try ln -s /tftpboot /tftpboot/tftpboot chown nobody.nobody /tftpboot/tftpboot on your TFTP-server and send again. Please ignore my last comment - Try the following steps instead: rm -rf /tftpboot/tftpboot # in case you already created /tftpboot/tftpboot ln -s . /tftpboot/tftpboot chmod 775 /tftpboot/tftpboot chown nobody.nobody /tftpboot chmod 775 /tftpboot which creates the symlink /tftpboot/tftpboot and fixes the owner and read/write permissions. added the following commands and still could not get tftp-server to work. ln -s /tftpboot /tftpboot/tftpboot chown nobody.nobody /tftpboot/tftpboot no messages in log file Secure file log Apr 24 10:40:14 blacksun xinetd[7628]: START: tftp pid=7733 from=192.168.200.1 Apr 24 10:40:37 blacksun xinetd[7628]: START: tftp pid=7735 from=192.168.200.1 Apr 24 10:40:57 blacksun xinetd[7628]: START: tftp pid=7737 from=192.168.200.1 error message from cisco router federal.net.nih.gov#copy run tftp Address or name of remote host []? 192.168.200.222 Destination filename [federal.net.nih.gov-confg]?
