While configuring dhcpd.conf on centos 4 I couldn't find option to reserve that ip addresses. I have subnet of 10.0.0.0 network of which i want reserve 1 - 50 addresses for my servers. I'll assign static ips to my servers & printers.
[Code]...
Is there any way to associate a group to subnet in dhcpd.conf? I want hosts in a specific group to be locked to an IP range defined in subnet. Something like this:
Code:
authoritative;
ddns-update-style ad-hoc;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.1 192.168.0.100;
option blah1;

I have a router with ddwrt on it that runs a DHCP server. What I want to do is only allow people who have pre-determined MAC addresses to get an address to get on my network. That being said I have a VM set up as a DHCP Server. Since doing this I will be setting the dhcp settings on my router to be a forwarder to the VM. Is there a way to allow only static leases in the dhcpd.conf file? I do not just any computer on my network to get an address I want to base it on MAC addresses.

I have tried creating the file and giving it permissions to be accessed, but that isn't solving the issue. I tried to go through some of the older fixes, and one was really close to working but lacked the same folders as I have.
EDIT: one solution that worked was to use ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid dhcpd3 -cf /etc/dhcp3/dhcpd.conf at0
I have a dual monitor setup (Twinview), both monitors are connected to my 1xNvidia MSI NX8600GT card...I've been using a 21.6inch HannsG HG216D (herein referred to as HG216D) monitor as my LEFT monitor, and a Dell 1905fp (herein referred to as 1905fp) as my RIGHT monitor.
I recently got rid of the 19inch 1905fp Dell monitor and moved my HG216D to the RIGHT and now I have a new 23inch DELL S2309W (herein referred to as S2309W) on the left. The new S2309W is connected to my computer via DVI cable and is configured Perfectly at it's native 1920x1080 resolution.
However I can't for the life of me get my HG216D back to it's native 1680x1050. The HG216D is connected via VGA cable that is also routed thru a KVM, I realize this means that this monitor can't/won't be auto-configured. However I should be allowed to set it manually right?...
Code:
Won't let me select 1680x1050 for the HG216D resolution, it will only let me select 1440x900 MAX, there is no option for 1680x1050, (See attached: screenshot)

My Dell Precision Workstation was shipped in 2003 with RH Linux installed (most likely RHEL 4) - though not sure.
At the time, the dual monitors worked by replacing the X86config file with one sent from Dell.
Since, my disk failed and I had to replace the disk and reinstall RH Linux with the shipped disks, RHEL 5.
Now, I can not find X86config; rather, I have been trying to update the Xorg.conf file with no to limited success.
Both monitors are driven off of one Nvidia Quadro FX 1300 videocard. My goal is to get the screen to span both.
Does anyone have a Xorg.conf file that would support this?

View 4 Replies View RelatedI've been scanning the apache2 docs for the past few days and have not come up with an answer my following issue:
In my httpd.conf file, at the very end, I have the line
Include conf/vhosts/vhost_*.conf
However, when I run apache checkconfig or try to start apache, it gives me the error:
httpd: Syntax error on line 993 of /etc/httpd/conf/httpd.conf: Could not open configuration file /etc/httpd/conf/vhosts/vhost_1.conf: Permission denied
It appears as if the Include line is correct - in terms of it grabbing the first virtual host conf file. However, I'm confused on the permissions. the /etc/httpd folder is owned by root:root, as are the subfolders. As a test, I chown'd the conf/vhost folder combination and all the vhost files to apache:apache to see if that made a difference, and it appeared to make no difference at all. The log files don't contain anything (assumed because apache isn't starting). If I place the contents of the vhosts in a singular vhosts.conf it works - with the permissions set to root:root. I'd like to avoid having to use one vhosts conf for the configuration I'm trying to achieve - as it would make my life a lot easier.
I have a question regd. reservations for the system GID's/UID's in Redhat. I understand that numbers <500 are reserved for systems and >500 for users. In the former, is there a range that is reserved for private use (like the 10. range in the case of IP addresses)? I need to create a system group and user and specify a GID and UID and I would like to make sure that the numbers do not conflict with some other package.
View 1 Replies View RelatedHave DHCP3 running on an ubuntu server. Using config of the below but the 10.1.1.2 address is being given to a windows pc (which does not have that MAC address). Tried getting windows to release ip address, then clearing the lease file and restarting dhcp3 service, then renewing dhcp request from windows, but address 10.1.1.2 is still given.
Code:
it appears i haven't quite grasped the meaning of dhcpd.conf despite the numerous tutorials i went through in the internet and the detailed read of dhcpd.conf that i did. what i basically want to put you in perspective, is to have all the pc's in my home network (desktops and laptops) regardless of any other settings, to send their computer name (hstname basically) to the dhcpd (during the handshake)... then the dhcpd will use that name as the hostname and append the known domain name, thus creating an entry (an A record and a PTR record) in BIND....
so say a laptop comes into wifi range of the domain "myhome.org."... i take it that during handshake, the laptop will send its hostname (i don't know what that will be for winXP and win7 dhcp clients, but i presume it will send the output of command 'hostname' for linux clients - or at least thats what i would like it to send....).say "nass-notebook" Then the server will append "myhome.org." and it will update the DNS with an entry looking like[URL].. corresponding to some ip address.

I am trying to provide dynamic IP addresses for devices that are on a different VLAN (101). The server is currently providing 172.17.x.x/16 range for its own VLAN (417).

However my laptop on the VLAN 101 keeps getting IP of 172.17.x.x/16 range..
I have a RHEL 5 64bits installed on a virtual server. I set up a a dhcpd server for one subnet last week and I have a strange behavior : the IPs are provided in a decreasing order. What's the? So I have tried to exchange range values but the result remains the same.

I've been using dhcpd for address assignments to PCs for a very long time with no issues. I recently upgraded from lenny to squeeze and now dhcpd seems to have new behavior which I can't seem to change. Here's what I want to do. First, I have a simple situation and don't want to get involved with dynamic DNS updates. I have host statements for each of my PCs and a range statement for cases where I install a new device and don't yet have a host statement for it. Previously, I could discover the ethernet address for the new device from the dhcpd log and add a host statement with an address of my choosing for the new device.
I'd then restart dhcpd and do something like reboot the device or issue an ipconfig /renew statement on the new PC. What would happen is that the old dynamically assigned IP address would be NAKed and the device would do a DHCPDISCOVER, etc. and get the new IP address I specified in the dhcpd.conf host statement. In squeeze, this no longer works. The client asks for the old address it got dynamically and the server just says yes. I can't seem to find a way to get it to NAK the dynamic address and use the new address I've specified in the host statement. I'd appreciate any enlightenment on how this is now supposed to be done. Here's my simplified dhcpd.conf file:
authoritative;
log-facility daemon;
ddns-update-style none;
[code]....
Note that the address here was assigned based on a previous range statement and isn't consistent with the above config file.
I have a dhcpd server running CentOS and Webmin. I noticed in my lists of expired leases some of the lease times are only a few hours even thought I have lease length set to 1 week. I want to keep a lease for a week even if the device requests that it be expired. Is there some way I can do this in dhcpd? I am attaching a screenshot of some of my lease times listed in Webmin.
