[syslinux] tftpd error message (File not found)

[Matthew J Fletcher]

Hi,

when i look in my syslog i see.

(syslog)
Mar 12 04:40:49 linuxdev in.tftpd[15218]: RRQ from 10.1.5.121 filename 
scx.elf.gz
Mar 12 04:40:49 linuxdev in.tftpd[15218]: sending NAK (1, File not found) to 
10.1.5.121

here my client has asked for a file, and tftpd has said that it does not exist 
in its path (or cannot access it).

looking in the tftpd.c (from 0.36) i see that on line 779 this error can be 
caused.

<snip>
      ecode = (*pf->f_validate)(filename, tp_opcode, pf, &errmsgptr);
      if (ecode) {
	nak(ecode, errmsgptr);
	exit(0);
      }
 <snip>

i run the tftpd server from xinetd as root, so it cannot be a permissions 
problem (i believe ?).

(/etc/xinetd.d/tftp)
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -vvvvv -s /home/scxnucleus/ScxV6 -T 4000000 
-r blksize -r blksize2 -r tsize -r timeout -r utimeout
        disable                 = no

also if i restart the tftpd service '/etc/inet.d/xinetd restart'

the client can then load the file correctly, and i see in syslog

(syslog)
RRQ from 10.1.5.121 filename scx.elf.gz
