[syslinux] Problem in getting tftp transfer to succeed
Setup:
Server: Mac OS X Server which serves dhcp and tftp requests
client: Acer with PXE boot agent 4.0.19
file to transfer: -rw-r--r-- 1 root wheel 10988 Apr 12 13:50
pxelinux.0
The default tftpd daemon doesn't support the tsize option (I think,
look at the packet trace at the end, it reports the file isn't found,
but I think this is because of tsize ... but I could be wrong)
So I changed the tftpd with tftpd-hpa, I had to comment out:
/* Set up the supplementary group access list if possible */
/* /etc/group still need to be accessible at this point */
#ifdef HAVE_INITGROUPS
setrv = initgroups(user, pw->pw_gid);
if ( setrv ) {
syslog(LOG_ERR, "cannot set groups for user %s", user);
exit(EX_OSERR);
}
#else
#ifdef HAVE_SETGROUPS
if ( setgroups(0, NULL) ) {
syslog(LOG_ERR, "cannot clear group list");
}
#endif
#endif
because otherwise I couldn't get the daemon to function.
I tested the tftdp with a tftp client on the command line and it works.
Now when I try to load pxelinux.0 with the Acer PXE client I get the
following error: Missing mode.
Here is the packet trace ...

So the tftp transfer for pxelinux.0 should have succeeded, regardless of the standard or tftp-hpa tftp server. Only the pxelinux tftp requests (for /private/tftpboot/pxelinux.cfg/default e.g) depend on the tsize option. So I think this is a more general problem - maybe even with your network card. Could you perhaps try to set this up under a linux server, and after that switch back to MacOS? I think noone tried this under MacOS already (anyone?), though tftp-hpa also works on Solaris, AIX and even cygwin.

Perhaps the client insists on a special (or not even special) option to come from the server. I've seen clients refusing to boot if they get the boot file via the bootp options, but boot fine with the dhcp ones. This would be options 'bf' vs. '66' AFAIR. Take a deep look at the dhcp packets the server sends out, perhaps you can get the server to support these options for your pxelinux clients. If you need help with that post the whole DHCP request (4 packets - Discover, Offer, Request, Ack ) for both servers, and see what we can do about this.
