tftp problems continue

[Grant Willey]

still cannot get a Windows PC to successfully pull any files off of my HP9000. I cannot even get tftp to transfer files (as a test) to or from itself. I've got everything setup like you guys suggested, but when I go to test the tftp, I get Timeout error messages. The man pages aren't helping me. Can you help?

I was unaware that Windows offered a tftp client. They do have an ftp client that works, if crudely. I first used tftp in 1988, across a Novell Network from a Unix host to a H/P printer. So this is an old, old standard that isn't terribly effective or secure.

In order to really debug the issue, we'll need more information. What version of Unix, and what patch level? What kind of Windows? What other kinds of connectivity work or don't work? What is the command you're using? What does netstat show?

Usually, matters like this are a lot more confusing than difficult. We'll help you figure it out.

tftp? Trivial File Transfer? port69/udp? From hp-ux :

lsof -i udp:69

But the real test from either O/S is telnet'ing to the port number:

telnet 192.1.1.117 69
Trying...
Connected to `hostname`
Escape character is '^]'.

What's the unix to windows connection?

What is the command you are using from the Windows PC to attempt to get files from the HP-UX tftp server? Also what version of Windows are you running on the PC?

Hi,
I try once's tftp from cisco router to Windows.The tftp client I loaded from CISCO website.
Couple of time tftp from cisco to window fails.Later on,I realize you need to launch the tftp client upon/during transfer file.

Is it the same as you problem I don't know.But something to share about.

regards

I'm using WinXP Pro on a laptop. What I'm doing is this:

Connected to the laptop Com1 port is a Cisco wireless access point. To update the flash memory on the AP, I have to download the image from a TFTP server. So I've got a client terminal emulation package loaded on the laptop that connects to the HP-UX server. So basically, the laptop is the middle man between the two. I am now getting timeout errors when trying to TFTP the images over to the AP. The timeout error displays almost immediately after typing the command to pull the image from the HP-UX server. Any ideas??

Cisco's tftp program is rather poor. It seems to have major problems and gets confused when the PC has multiple interfaces. You could probably get it to work if you closed all but one NIC and reinstalled it but you are probably better off with SolarWinds':

which acts as both server and client and understands multiple NICs.

Get a copy of 'tcpdump' and see what's going on on what port.
