similar to: "Secure" tftpd source for Linux?

Hi, I have a tftp client which loads quite happily from a tftpd built from netkit-tftp-0.16 but which fails to load from from a tftpd built from tftp-hpa 0.29. In both cases, tftpd was built from pristine sources and run from xinetd under Redhat 7.3. [netkit-tftp-0.16 is the ancestor of tftp-hpa, predating HPA's maintenance of same] [the tftp client also.. .. fails with the prebuilt tftpd

Hi. I don''t know if this one is known, but I can''t recall seeing anything about it. If it is old news I apologize. I discovered a bug in the inetd that comes with NetKit-B-0-08 and older. If a single SYN is sent to port 13 of the server, inetd will die of Broken Pipe: write(3, "Sun Jan 12 21:50:35 1997\r\n", 26) = -1 EPIPE (Broken pipe) --- SIGPIPE (Broken pipe) ---

I just wanted to post this so that it was out there and Googleable. Hopefully it will save other people a bit of time. If you have a Cisco phone (I was testing with a 7970, though presumably it would affect 7960 and others as well) that is looping trying to fetch the CTL tlv file - it may be because you are using Debians 'tftpd' (should be netkit-tftpd...*cough*hey, Debian

Hello, On my previous TFTP server I had logging. I did see all requests in logfiles. On my current TFTP server I have also added the options '-v -v -v', but nog logging. At least I can't find it them in /var/log/*/* Where does tftpd-hpa writes it's logging? Groeten Geert Stappers -- Leven en laten leven

Hi, This is my current patch queue. The patches are independent, AFAIK, so feel free to cherry-pick or reject them independently. The bottom one was needed for a successful build here; the top one contains all the modifications you requested on IRC, and more. Meanwhile I hit one of the four stray TABs in tftpd.c, and decided to get rid of them. Comments welcome. --- Ferenc Wagner (5):

Hello, Peter and others! there are some issues regarding the tftp-hpa server: 1. Running as Windows service seems to require that the application does not detach (otherwise "net start" says smth. like "could not start, the service didn't report any errors"). The attached patch adds the option "-n", which can be used to have tftpd run in foreground.

AI_CANONNAME is only relevant when the resulting official name is used, which is not the case in tftpd for the address to bind to. Also AI_ADDRCONFIG isn't helpful. This flag is good for sockets used to connect(2) somewhere. But for listening sockets it makes tftpd fail to start when -a 0.0.0.0:69 is passed and no network device is up yet. This addresses Debian bug

Hi, I have been running TFTPD server for 3 weeks and performed about 100 deployments. After that, TFTPD started throwing the follwing errotrs in /var/log/messages Aug 20 21:52:55 RTP-OSP-Server tftpd[7146]: warning: cannot open /etc/hosts.allow: Too many open files Aug 20 21:52:55 RTP-OSP-Server tftpd[7146]: warning: cannot open /etc/hosts.deny: Too many open files Aug 20 21:52:55 RTP-OSP-Server

I configure the system of remote boot. Almost all was done. But one simple problem. tftp doesn't download pxelinux.0 from boot-server, in.tftpd is running at. Problem isn't in pxelinux.0, but in protocol itself. I've created test file "test" in /tftpboot and tried to download it but "Timeout occured". From /var/log/messages: Mar 27 16:32:27 dk in.tftpd[26576]:

> Correct. Like most UDP-based inetd services, tftpd is intended to be run in 'wait' mode. When the first request arrives, inetd starts the service but does not read the incoming packet (it can't, because it has no way to pass it along to the server). After that, inetd ignores that socket until the server exits. This isn't critical for tftp, but it does help to keep down the

Hi! I am using OpenBSD 4.4 with the build-in TFTP-Daemon for PXE. Distributing OpenBSD works fine. Now I want to distribute OpenBSD and WinPE. I've installed PXELinux 3.72 and configured it. Works also fine for PXELinux and distributing OpenBSD. To distribute WinPE I need a remap rule (\ -> /) for the TFTP-Daemon. I've created a file /etc/tftpd.remap with the following rule: rgG \\ /

Hi, I've been struggling with this problem for the last couple of hours and am nowhere near solving the problem. I am trying to run a tftp server in a chroot jail. Now perhaps I am being paranoid, but I would like to have it launched from within its own jail even if it supposedly does a chroot itself and runs with a parameterizable user. I downloaded the atftp-server package and tried

Hi, I have a question on tftpd on Slackware - I know this is an embedded Linux forum, but I think it still must be the appropriate place to ask. I have hpa-tftpd V0.40 on Slackware 9.1. No matter what I do, I can't get files transferred to the tftp server. I just get timeouts - no messages in /var/log/messages or in /var/log/syslog - just dealthly silence. This is the configuration line

I've got in.tftpd configured on a Fedora Linux server. The service is configured to boot printersm and sun sparcs. The printers boot fine, but there's a problem with the sparcs. When the sparc sends an initial request for a file, in.tftpd forks a process to handle it. If I do a "netstat -pan | grep tftp" I see that this forked process is listening on local address

Hello, we have two diskless machines in a routed network. Both get their IP adresse and tftp configuration via dhcp. When we start one machine all works well, when the second machine tries to download the kernel via tftp we get this error: Jul 8 09:49:52 voyager2 in.tftpd[8374]: RRQ from 10.63.5.122 filename /andreas/pxelinux.0 Jul 8 09:49:53 voyager2 in.tftpd[8374]: tftpd: read: Connection

It seems that tftpd-hpa is more suitable at serving arbitrarily large files (greater than 65535 blocks long; with pxelinux.0 using a default block size of 1408 this is 92,273,280 bytes) as atftpd will complain in the log stating "Requested file to big, increase BLKSIZE". I saw that a while back HPA mentioned that atftpd was probably more scalable (number of clients) while tftpd-hpa is
