Where are people getting this interpretation of the “133” number?
Typically when I’ve seen the last octet in a Default Class C subnetted address with a non-zero or non-broadcast (255) value, I’ve seen that number interpreted as the Host portion of an address, the result then is that a specific address instead of a range of addresses is specified.
But,
That doesn’t even apply here… From the original post it appears to be a value for the “server-identifier” as follows
server-identifier 192.168.213.133;
Not having seen that before, I decided to find out what this setting is, and in the DHCP MAN pages as follows
The server-identifier statement
server-identifier hostname;
The server-identifier statement can be used to define the value that is sent in the DHCP Server Identifier
The use of the server-identifier statement is not recommended - the only reason to use it is to force a value
The usual case where the server-identifier statement needs to be sent is when a physical interface has more…
Supplying a value for the dhcp-server-identifier option is equivalent to using the server-identifier state-
server-duid EN enterprise-number enterprise-identifier ;
So, it appears to be like much like the other things I see in the OP’s config file which I already alluded to… He’s setting options which aren’t necessary and in this case it bit him (the others aren’t obviously harmful yet).
So, I again highly recommend the use of a config tool like YAST (which I previously posted about) to do your configuration unless you’re and even then I don’t know if an expert would turn down the opportunity to use a config tool instead of relying entirely on his personal expertise.
Hopefully helpful NOTE:
When configuring DHCP in a “non-enterprise” environment which typically means you don’t have LDAP or some other DHCP-integrated network security running, you should specify things like a Domain Name, although DNS might be desirable. Specifying may be result in no harm/no foul, but like this other setting can also prove to be a real problem.
Lastly, if you’re curious what a “basic” /etc/dhcpd.conf should look like, the following is an example of what is absolutely minimally necessary(specifies DG and issues an address, a couple DNS servers and default timeout) and was generated by the YAST DHCP configuration applet
/etc/dhcpd.conf
option domain-name-servers 127.0.0.1, 127.0.0.1;
option routers 127.0.0.1;
default-lease-time 14400;
ddns-update-style none;
subnet 192.168.248.0 netmask 255.255.255.0 {
range 192.168.248.245 192.168.248.250;
default-lease-time 14400;
max-lease-time 172800;
}
