rarp vs. dhcp
- you mentioned that your build server is "in a different IP segment" , see...
-- RARP will only work within the same subnet ;
in other words, RARP does not span or cross subnet boundaries, and is not routeable ;
- if your build server is in the same subnet as the target box, then netboot will work fine ;
- but if you absolutely need to use a build server from another subnet, then you'll have to use DHCP in yout BOOTPARAMS ;
good luck, and success !

ipsec_masktobits
IPSEC_GOODMASK(3) Library Functions Manual IPSEC_GOODMASK(3)
NAME
ipsec_goodmask, ipsec_masktobits, ipsec_bitstomask - check if Internet subnet mask is valid, convert Internet subnet mask to bit count,
convert bit count to Internet subnet mask
SYNOPSIS
#include <libreswan.h>
int goodmask(struct in_addr mask);
int masktobits(struct in_addr mask);
struct in_addr bitstomask(int n);
DESCRIPTION
These functions are obsolete; see ipsec_masktocount(3) for a partial replacement.
Goodmask reports whether the subnet mask is a valid one, i.e. consists of a (possibly empty) sequence of 1s followed by a (possibly empty)
sequence of 0s. Masktobits takes a (valid) subnet mask and returns the number of 1 bits in it. Bitstomask reverses this, returning the
subnet mask corresponding to bit count n.
All masks are in network byte order.
SEE ALSO
inet(3), ipsec_atosubnet(3)
DIAGNOSTICS
Masktobits returns -1 for an invalid mask. Bitstomask returns an all-zeros mask for a negative or out-of-range n.
HISTORY
Written for the FreeS/WAN project by Henry Spencer.
BUGS
The error-reporting convention of bitstomask is less than ideal; zero is sometimes a legitimate mask.
