Thanks Christopher... I've added the create parameter as you suggest,
however the problem persists.
In /var/log/messages I continue to get a "in.tftpd [5-digit no.,
incrementing by 1 each line] cannot bind to local socket: Address already
in use".
I've stopped iptables (presuming that means all incoming packets are
accepted). Following Nate's suggestion, I've stopped xinetd and then
netstat doesn't show any listening on tftp/69 udp. I can telnet and ftp
to the server without problems.
Anyone with suggestions on how to troubleshoot/interpret the address
already in use message? I'm at a loss at this stage.
Thanks again.

Hi John-Paul,
Well it sure looks like from the syslog that something else is on your
tftp
port, so please verify. -- or -- tftpd hasn't been configured to allow
the
creation of files in your tftphome directory.
Here's my /etc/xinetd.d/tftp file:
# default: off
# description: The tftp server serves files using the trivial file
transfer
\
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware
printers, \
# and to start the installation process for some operating systems.
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s -c /tftpboot
per_source = 11
cps = 100 2
}
The -c in sever_args tells tftp to allow creation of files. security risk
--
you have been warned, so make sure your tftp port is blocked only to those
who should have access!
Cheers,

Hello List...
I'm having problems setting up a tftp server on my rh8.0 box. I want to
use it to backup cisco router configurations.
I've created a file called startup-config in the tftpboot directory with
chmod 777 and chown nobody:nobody. The directory tftpboot is also 777,
nobody:nobody.
>From the router I try a "copy startup-config tftp", and input the ip
address at the next prompt. I then get the error:
%Error opening tftp://10.11.35.28/startup-config (Undefined error)
In /var/log/messages I find a long list of errors:
..." in.tftpd[31383]: cannot bind to local socket: Address already in
use"
The output of netstat -a | grep tftp is:
udp 0 0 *:tftp *:*
Thanks - Any help on this would be greatly appreciated.
/j-p.
