tftpd server S not responding
A STATEFUL firewall with ?ip any any? can and will still block asymmetric communications due to the firewall keeping track of state (hence tha name stateful firewall). Tcpdump on your servers /other/ NICs and you?ll see the tftp traffic leaving your server on some other NIC (probably on with the default route). The upstream firewall will then block the tftp response if it never saw the

nilo -> tftp-hpa interaction
I downloaded nilo and oskit from www.nilo.org. Added pcnet32.c linux-2.0.39 driver to oskit. Compiled nilo with pcnet32 and produced boot floppy image. Use it inside vmware vm. My aim is to be able to test pxelinux using vmware+nilo and not a real machine. Floppy starts, detects nic, receives ip from dhcp server, requests boot image to tftpd-hpa, then crashes when talking to tftp. Is

help diagnosing tftp server on centos 5
Hi all, I have a centos 5 box I have setup, current with updates. (I have done this many times on centos 4). I did the yum install tftp-server, changed the /etc/xinetd.d/tftp file as shown. # default: off # description: The tftp server serves files using the trivial file transfer \ # protocol.

[tftp-hpa] [PATCH] support for named pipes
...m it? That way you could write a persistent daemon that would read the pipe and respond with custom content. Client information in this case would be: Source IP address Destination IP address (in case the TFTP server is on a multi-homed host) Source TID/UDP port TFTP transfer mode (octect or netascii, or extension?) It's too bad we can't tell from the TFTP request if it's a UEFI or Legacy boot mode client. Could send either Legacy pxelinux.0 or UEFI syslinux through the same filename Just a thought, -- Philip Pokorny, RHCE Chief Technology Officer PENGUIN COMPUTING, Inc www.pen...

OT: Aastra 57i configuration via TFTP problem
I am currently testing a 57i unit. No problems configuring the phone's config via phone/web UI. We are trying to avoid using the web UI, the reason is it will take a long time typing the softkey xml applications URIs on each phone, so we chose TFTP. Tried configuring the phone via a TFTP config server, but no changes took effect. I wonder why it doesn't work with TFTP even if I was

tftpd: read(ack): Connection refused
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
