Assuming you have connectivity, I have found sometimes that you don't have
to specify the pathname on the Cisco.  Other times, I have found you have to
specify the whole kit and caboodle, and URL it to boot.  I Now that I think
about it, I'm sure you tried that, too...oh well.  my two cents.

Subject: Re: tftp configs... ?



I have used tftp successfully with older RH installs... This is the first
time I've had a problem..
xinetd looks ok, ... ???

I am trying to store a bunch of router cfg's for backup...

Long term goal, cron runs expect script weekly, backs up all routers... :)


Current errors:

Remote (Cisco )Router says:
{
TFTP connection fail(-1).

file tftp:/tftpboot/temp.cfg cannot be opened for write (TFTP write error)
Cannot write buffer to file
Cannot copy from config: to tftp:/tftpboot/temp.cfg
}

I  have created an empty file, and alsoo tryed with no file....
{
[root at proxy1 /tftpboot]# ls -l
total 0
-rwxrwxrwx    1 nobody   nobody          0 Apr  3 18:46 test.cfg
[root at proxy1 /tftpboot]#
}

The Kernel: uname: kernel 2.2.22
