Gettting Syntax Error for an entry setuped in file /etc/bootptab for relaying bootp requests.

[Prasad Joshi]

Hi All,

We are having a ignite server as well as pxe server for OS installation on HP-UX and Linux servers respectively. Having these to servers in the same subnet is creating a problem. So,
what we are trying to do is, shutdown the DHCP on the PXE server and relay the bootp requests from linux client to Linux PXE server. I think this should work.

Now, to relay the bootp requests I have added these lines in the /etc/bootptab

<<<<<<< a part of /etc/bootptab >>>>>>>>>>>

galapagos:\
ht=ethernet:\
bp=10.216.152.40:\
th=2:\
hp=8

swlx42:\
tc=galapagos:\
ha=00093D111D03:\
ip=10.216.154.42:\
hn:\
sm=255.255.248.0

<<<<<<< a part of /etc/bootptab >>>>>>>>>>>

galapagos ==> is the PXE servers hostname and its IP is 10.216.152.40

swlx42 ==> machiine on which I want to install LINUX. IP->10.216.154.42 and MAC 00:09:3D:11:1D:03



Now, when I try installing OS on Linux machine through PXE. I am getting these error msgs in the file /var/adm/syslog/syslog.log

So, there is some problem with the entries that I have made in the file /etc/bootptab.

Can anyone please tell me the correct syntax for writing these entries?

Thanks and Regards,
Prasad.

These are the correct logs from syslog.log file.
