TFTP Help

twiggy87

Im having a tftp issue, in that I cant seem to get a connection.

Im trying to upgrade the ios on my 1600 using an old pc I found but I cant seem to get them to communicate. I connect them via a crossover cable into the 10mb port on the router, setup the routing protocol and put them in the same subnet

192.168.1.1 255.255.255.0 - Router
192.168.1.2 255.255.255.0 - PC

and I cant think what the problem is, I really need some help because I have no clue what im doing wrong.

Humper

Could you post the config of the 1600? Remember there is no need to configure a "routing protocol". I am assuming by that you mean RIP,static ..etc?

You will need to configure the e0 interface on the router with some commands like this

ip address 192.168.1.1 255.255.255.0
no shut

on the PC make sure its using 192.168.1.2 and that the subnet is a class C 255.255.255.0 with the gateway being 192.168.1.1

Make sure that it is infact a cross over cable, check for LEDS on the PC. It could be a cable or a NIC issue.

Could this PC access the internet before plugging it into the router?

These are things you need to check

Your subject mentions tftp. Are you running a tftp server service on the PC?

Did you check the configuration of the PCs TFTP server -- does it allow remote connections? The one I use has a default configuration that doesn't allow connections.... so check that.

Have you used that cable before and know for sure it works?

Can you ping between the router and PC?

I am running Solarwinds tftp server, I just cant ping between the pc and the router. The pc connects to the internet perfectly. I was trying to use rip as the routing protocol but it shouldn't be a problem because the pc would be a directly connected route anyway.

So does the PC connect through the router to get to the Internet? Can you give us an ipconfig from the PC? Is your computer running a firewall?

mikej412

If your IP configs and cable are okay -- look for firewall software.

You've go to fix the ping issue first.... then TFTP.

Solarwinds.... yeah.

Did you go to File, Configure, Security and see if it is set to "Transmit and Receive Files" or "Transmit Only"

This one defaults to "Receive Only" if I remember correctly.
