need info for tftp entry in inetd file

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.

Re: need info for tftp entry in inetd file

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.
Best wishes,

Ganesh.

Re: need info for tftp entry in inetd file

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.
