tftp and cisco

["Jephe Wu" <jwu asiansources com>]

I have a Redhat Linux server running on our LAN,(192.168.0.2) and a Cisco
2601 router (192.168.0.254), I hope to download cisco route configuration
file to linux server by tftp . so I enabled tftp in /etc/inetd.conf on Linux
server as follows:

tftp   dgram   udp     wait    root    /usr/sbin/tcpd  in.tftpd /tmp

and /tmp is set to drwxrwxrwx . anyone can write to it.

but when I telnet to route and route# copy running-config tftp , it reported
error message.

Writing shanghai--isdn-confg ..... [Failed]

why? how should I do?

Thanks
