Special Forums IP Networking i have dhcp yet i get the same ip , always!!!!how do i change it? Post 302227753 by wrapster on Friday 22nd of August 2008 01:23:10 AM

Yeah even i had the same hunch regarding the lease period..
But this happens only in solaris.
When i was using xp the dhcp used to turn out different IPs each time i connected to the network
Code:
'd also make sure your router/dhcp server isn't looking explicitly for the MAC address of that interface and assigning it an IP based on that MAC address.

How do i check for this?

bptojdb(8)						      System Manager's Manual							bptojdb(8)

NAME
bptojdb - Converts bootptab entries into permanent, static IP entries for JOIN databases. SYNOPSIS
/usr/sbin/bptojdb [-m | -f] filename OPTIONS
Create client IDs for Microsoft DHCP clients. Microsoft does not use the client's MAC address by itself as the client identifier. Instead, it prepends a 01 (Ethernet) to the MAC address and changes the hardware type to 0 (generic). If the clients in your bootptab file are Microsoft clients, you will need to use the -m option. Create client IDs for FTP Software's DHCP clients. FTP Software does not use the client's MAC address by itself as the client identifier. Instead, it creates a 16-byte client identifier with the prefix "cid-". If the clients in your bootptab file are FTP Software DHCP clients, you will need to use the -f option. DESCRIPTION
The bptojdb program reads entries in a standard bootptab file and creates permanent, static IP entries for the JOIN databases. After read- ing the bootptab file, bptojdb displays to the standard output entries in a format suitable for the jdbmod utility. Each MAC address in the bootptab file is given a static IP address with a permanent lease. To store the information in the JOIN databases, run jdbmod with the converted data. For example: bptojdb bootptab | jdbmod FILES

Commands: jdbdump(8), jdbmod(8) bptojdb(8)
