need info for tftp entry in inetd file

[devarshi]

As per the anual patch upgrade on hpux 11.11 m/c one patch says that we have to modify the tftp entry in the inetd file as given below:

tftp dgram udp wait root /usr/lbin/tftpd tftpd -s


Can anyone tell me what is the significance of -s at the end of this entry. The patch says that it is necessary for the fixing the CR JAGad25107 / SR 8606155794, dunno what it is meant for.

Regards

Hi,

man page shows that..

-s

This option enables tftpd to work in the Service Guard environment. This option is required for some tftf clients. These clients reject the tftp reply received from a different IP address than the one requested when the server's interface is configured with an alias IP address.

[Laurent Menase]

apparantly with that option, tftpd will answer with the ip alias source address to which the tftp request was sent.

ie
you have 2 aliases on the same interface
lan0 1.1.1.1 and lan0:1 1.1.1.2
without this option
if you send a tftp request to 1.1.1.2 the source address of the answer will be 1.1.1.1
with the option it will be 1.1.1.2.
