Hi All,

does the -s in the path in this file represent a soft link.? If so, where would I find this link's path..?

[root@localhost xinetd.d]# cat tftp
service tftp
{
       socket_type             = dgram
       protocol                = udp
       wait                    = yes
       user                    = root
       server                  = /usr/bin/tftp
       server_args             = -s /tftpboot
       disable                 = no
       per_source              = 11
       cps                     = 100 2
}

Doing a find / -name tftpboot -print gives the following,

[root@localhost xinetd.d]# find / -name tftpboot -print
/var/tftpboot
/var/tftpboot/tftpboot

Is one of those the link's location.? Cheers.

according to man tftpd

-s  Change  root  directory  on startup.  This means the remote host
    does not need to pass along the directory as part of the
    transfer, and may add security.  When -s is specified, exactly one
    directory should be specified  on  the  command  line.
    The  use  of  this option is recommended for security as well as
    compatibility with some boot ROMs which cannot be easily
    made to include a directory name in its request.

Hi All,

Alex, if I'm trying to upload a running-config file of a cisco switch to
/tftpboot, what do I specify at the switches prompt,

Switch>en
Switch#copy run tftp
Address or name of remote host []? 192.168.168.12
Destination filename [running-config]? running-config

Is this correct, above.? I can't seem to get it to work.

Switch#copy run tftp
Source filename [running-config]? running-config
Destination IP address or hostname []? 192.168.168.12
Destination filename [running-config]? running-config
Building configuration...
.....
%Error opening tftp://192.168.168.12/running-config (Undefined error)

Cheers.
