I have intall a REdhat 9.0 as a server and Ive configure to act as a DHCP however Im having technical problems b/c the file /etc/dhcpd.conf does not exists. I went to the text edit and I created :
subnet 192.192.168.100.0 netmask 255.255.255.0 {

Hi,
I need to get a script together to edit the dhcp service configuration file dhcpd.conf.
Mac addresses are defined in classes ex.
class "HOST1" { match if substring (hardware, 1,18)=00:11:11:FF:FF:FF;}
class "HOST2" ...

Hi,
I've setup DHCP Server on RH linux AS3 and everything works fine except static routes. They are not getting effected on client systems.

Hi there,
I am having a small issue with the mail function on our controllers. Recently we set up all the boxes as NFS slave servers and mail sending was not affected. We then had to change the servers addresses in resolv.conf and now email is being queued and not being sent.

Hi, I have a file with the following line
open (unit=2, file='t0_p0.DAT')I want to change the value of the above zeros with variables $i and $j using a simple perl one linear.
I've tried the following but it doesn't work
perl -i -pe "/open/&&s/t\d+_p\d+/t$j_p$i/" fileThanks! (3 Replies)
This is my first time posting here...so be gentle.
Suppose I have a test.conf file that contains a value such as a IP. I would like to be able to use the Dialog Utility in Linux to allow me to enter the new IP in a Dialog form...and the results get saved into the test.conf file in the place... (4 Replies)
Hy everybody,
Within a dhcpd.conf file, we got some fixed IP adresses from 192.168.0.1 - 192.168.0.254.
Sample:
#ddns-update-style interim;
ddns-update-style none;
ignore client-updates;
deny client-updates;

Hi Experts,
Our DHCP server currently answers the DHCP Discover requests from ServerX. In our dhcpd.conf file there are parameters defined for ServerX.
Now we introduced some additional Servers into the network and want them to get service from the same DHCP server.
Similar configuration... (13 Replies)

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
