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.

I've configured my TCP/IP to have the right protocols to access the internet such as TPC/IP, subnet mask, gateway and dns server but still Im not able to ping anything to the internet. Anybody who has some few good words for me? I need help. Thanks. (2 Replies)
Hello I'm trying to get my sun box to keep its' ifconfig info after reboot. I can get it to keep the IP but it won't take the subnet mask. I'm using a /30 address.
thanks

I understand how to change the ip address permanently however, I need to also make a permanent change to the subnet mask. How would I accomplish this. (5 Replies)
Hi,
I have a task to edit the subnet mask in almost 100+ solaris servers.Few of the servers are configured with IPMP.There will be no change of IP address or default gateway.If its a single IP we can bring NIC down,change the subnet mask in /etc/netmasks,then bring the NIC back to normal.But...

Is there a command that can lookup ip address, subnet mask, gateway, and dns all at the same. I know ifconfig can lookup ip address and subnet mask. I know route -n can lookup gateway. Not sure about a dns command. So I hope there is a way to lookup ip address, subnet mask, gateway, and dns all at... (2 Replies)

Iam attempting to add a client to NIM however the new client has a different subnet than master 10... & 193... , I've established from redbooks that it should be possible but can't find anything that states how?
Does anyone use nim in this way? (5 Replies)
