PostPosted: Fri 11 Nov 2011, 22:13    Post subject: TFTP Server in DNSMASQ ONLY allows reads - no Writes!  
Retracted earlier comments.

The TFTP commands I've found to not match the tftp command in Busybox. I have no way to test this. I have noticed that the tftp command in a Puppy terminal does not seem to work when trying to use it to transfer a file to the running TFTP host that is used by this very Netboot facility. BUT, IT DOES WORK TO TRANSFER A FILE FROM THE Netboot facility.
Code:
tftp -r pxelinux.0  -g localhost
To understand correct client command invocation, type "tftp" in a terminal.

Edit: The following CANNOT be done. Its the product's version of security.
Code:
It must be investigated to find the parm in DNSMASQ start to allow TFTP to allow users writing to this server. (BUT, beware as there's a very good  local security reason why you might NOT do this on a Netboot server, though)
Hope this helps
Edit: DNSMASQ DOES NOT ALLOW A CLIENT TO WRITE TO ITS TFTP service! .....the author

Hi puppy_newb!

I'm not familiar with Lucid 5.2.8. I'm using a pupplet based on Puppy 4.3.1. There is Pure-FTPd in the network menu and that is a normal FTP server and I think it is also available in Lucid. With this you can share files, but also should be able to upload files from a client. On the client you can use gFTP or the FTP command in the terminal.

Hi Magic,

Thanks for the gFTP information. The problem is that I need to copy switch config files from an HP switch which only allows copying files from it by TFTP. It just doesn't support FTP. Is there anyway I can get TFTP up and running on any Puppy?

Questions
  • Which HP Switch do you have?
  • Are you using the HP switch utilities or are you using a custom utility on your switch?

Drop it where? I have no idea what you talk about.
okay I have both computers running now. So if I "drop"
the ubuntu iso on one of my computer then I can start it
on the other ? Drop it where?

Any feedback you have, please post it there..
Where is here? This thread or the thread you linked to?

I guess you mean that after reading the txt then I know what you refer to
as just drop it. Where in the text do you tell where to drop the iso.
I am a poor reader of text. I drown in the words.

As I get it now finding the first text?

It sets up a server. That is not an easy thing. Nope I am out of here.

Hi GC

I have an HP 3500 and a 6200 that only support TFTP not FTP.

Which TFTP personality are you trying to be?

These are 24/48 port business class switches. Although, I have seen these switches before, I am not an authority on these specific models. Are you also using POE with these switches?

It appears from this entry that your switch may have SFTP capability as well.

HP, may have given you tools on your CD for backup and recovery of your configurations. Do you have that CD? If you have its part number, we may be able to find a manual on that CD's toolset. (If you're not using these switches for work, you're probably running a small village or have a very large family.)

Hi GC,

I would like a different TFTP Server to work besides dnsmasq. I have it working with RHEL5 using their tftpd service. I just want that software working in puppy. Do you know of a tftpd service port for puppy or another TFTP Server like atftpd?

Hi Aitch,

Thanks for your help but I have already looked into that solution and I can confirm it does not work for Puppy Linux 5.2.8. I guess I can confirm that there is no way a TFTP server which accepts files from a switch can be integrated to a remastered live DVD version of Puppy, unless I can be proved wrong. I have been working on this for about four months and not close to a solution at all.

Maybe you can try the Debian atftp package from here.

The dependencies are only libc6 and libreadline6, which both should be included in Puppy Linux. But the configuration you most likely need to figure out yourself. So far all TFTP-Netbooting has been mainly done with dnsmasq on Puppy Linux, which is not applicable in your case.

I just tried it. It doesn't work. I can't believe this isn't possible with Puppy.

Thanks for all your help! After 4 months the solution was commenting "ALL:ALL" from the /etc/hosts.deny file also known as TCP wrappers. Once this was un-commented, I was able to transfer files from a network switch directly to my Puppy Live DVD running a TFTP server at boot-up. I hope this helps somebody in the future!

Could you please clarify this? The "ALL:ALL" line is UNcommented by default. Had you changed it?

Oh sorry, what i mean is the ALL:ALL is there by default. I had to type # in front of the line in order to un-comment the line out. Once this was done, the TFTP server started working like a charm!
