Fedora Networking :: Way To Allow Only Static Leases In Dhcpd.conf File?
Dec 29, 2010
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 installed dhcp server on RHEL5.after instalation when i want to restart it.it shows failed message. rpm package is also installed.(dhcp-3.0.5-13.el5) dhcpd.conf file is also in /etc directory
How can I keep /etc/resolv.conf static ... as in preventing it from being changed by the network manager ... without actually disabling the network manager (so wireless users can get their wireless setup that includes IP address, but leave the resolver configuration as is)?
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.
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:
I have a dynamic Internet connection. My eth0 is configured to DHCP client. I need to rum one personalized command all time the dhclient renew the lease. I have a program that update the /etc/hosts with the new IP and I need to run this command when dhclient receive one lease update.
I have been routing network traffic based on MAC addresses, so we can distribute traffic evenly over a series of WAN IP addresses.Everything seems to be going well, but I have a very curious problem. One of the users can connect to the network without problem, but I don't see him in my network administration application (neither his MAC address or leased IP address).At the same time, I'm trying to identify other unknown computers on my network based on MAC addresses I don't have on file.
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 can connect to the internet and browse. I'm wired and using DHCP on a Windows network. Updating Ubuntu or downloading programs takes hours for 52MB of updates. Why? I read some articles that mention Network Manager needs to be enabled at the .conf file. Can I edit this using GUI or command line only?
Ubuntu Server 9.10I want to set up my dhcp server to also be my DNS server so do I skip these lines or point them at the same server that the config file is on?
I'm interested in learning how to start a wireless connection via the terminal rather than the NetworkManager applet. Every resource I've found on this subject talks about how you need to make a .conf file, then use wpa_supplicant. Is there a way to establish the connection without having to a create any file whatsoever? What are the steps for establishing the connection?
From what I've read, establishing a WEP connection is as simple as calling iwconfig and then dhclient. Are there similar steps for WPA2?
and I have share1 and its subfolder " subshare " the thing i have to do is that, i have 2 assign user1 and user2 to share1 that means user1 and user2 can only access share1 through password and user3 can access only its subfolder "subshare" i have done this upto first level permission of share1 not able to do for its subfolder "subshare"
If i type gedit while as root it give this warningQuote:(gedit:5655): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supportedGConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)And over the time, the paragraph block from GConf Error.... to ...was broken is repeated again and again
subnet IP netmask MASK { range IP START IP END ; default-lease-time 86400; max-lease-time 172800; }
And now in the /var/lib/dhcpd/dhcpd.lease file, there few entrie for the same IP. Sometime I've ten same entries for the same IP. Can I have only one entrie by IP? Is there any problems in my configuration of my dhcpd.conf file?
Is it possible to import an xorg.conf file from Debian to Fedora and have it work? The reason for this is that I have an older monitor that only offers 800x600 as the maximum resolution.
I want to run networking on my laptops in different environment (home, office, airport etc). I found that Netowrk Manager assigns information from DHCP although I requested fixed IP and configured the gateway and DNS. If I reconfigure the DHCP server so that there is no free IP address, the laptop refuses to connect. When I remove the interfaces from the network manager, I get the fixed IP address, /etc/resolv.conf is not overwritten from DHCP but WiFi connection cannot be established, there is no dialog for setting WPA-PSK. The static IP address seems to be taken into account only if the DHCP server is not found. I need the static address at home and in my office because I need the possibility to ssh to my laptop from another computer but I need IP from DHCP possibly authenticating against RADIUS (Eduroam) when travelling somewhere else. Is there an easy way how to achieve it and how to switch profiles easily? And I cannot switch DHCP off because some devices in my LAN cannot work without it.
I installed Fedora 10 and used dynamic IP first. Then I found out that bonding works with static ip only so I switched to static IP. But then, since I have 3 NIC cards, I configured bonding. I need help in these points:
1- steps to follow so that I switch from dynamic to static IP 2- steps to follow so that I configure bonding
I've seen a lot of questions on the forum about static IP's and how often people have problems configuring them. Here is how it works:
If you have a router in your network, the router is the boss. You can configure anything you want in your computer's network manager, but in the end, the router will win. Say you have 3 computers and configure each one for a static IP. If the router is still set to assign IP's dynamically, it may want to ignore that unless you boot the computers in order of IP#. In other words if you set your IP's to .001. .002, and .003 you have to boot the one with .001 first to be sure it gets that IP.
If you boot .002 first the router wants to assign it the first IP in the list; .001. If the computer will only accept .002 the router may (or may not depending on the router) eventually assign it .002, or you end up with a power struggle between the computer and the router, and have no connection to that computer.
That said sometimes setting IP's on each computer works, at least most of the time, again depending on the router. Some routers will assign the same IP to the same computer when each has individual settings, but even then you still have to deal with settings on each computer; a lot of work. And at some point you will probably still have a glitch or problem, at least temporarily. In my experience setting static IP's on the computers is hit or miss in the long run.
If you set the static IP's in the router and make sure the router recognizes each computer by it's MAC address it's a done deal. You can boot the computers in any order, they will always be assigned the same IP, and you don't have to do anything on any of your your computers or in your network managers to make it happen. Bada bing, bada boom, done. Less work, more stable network, fewer headaches.
I need to edit a line in a file in gedit, but its read only. I need to change
; default-sample-rate = 44100 to default-sample-rate=44800.
Would anyone know if there is an option to make a read only file editable? Judging by the responses to the thread I followed to enable my soundcard, it is possible, and perhaps there is some setting etc that needs changing
I got this message on Friday from just one domain. uote:mailsrv.forthnet.gr #<mailsrv.forthnet.gr #5.5.0 smtp; 554 5.5.0 Your message was considered to be spam by the FORTHnet Antispamming Policy and was not delivered to the recipient. The following spam tests returned positive for this message:FORGED_RCVD_HELO,RCVD_IN_BRBL. For further information visitWe are not a spamming community but it seems we have a statice IP address that has a Reverse lookup to "myipaddress.static.lyse.net" and not my email domain. Would setting a cname mail.mydomain.no -> myipaddress.static.lyse.net cure this problem or are there more tricks to be performedOnce I have cured the FORGED_RCVD_HELO I can move to getting the IP removed from BARACUDA.
I have just installed Fedora 10 on an old laptop and was quite impressed with how smoothly it all went ... until it came to setting up networking!
I have battled for three days now and I'm almost there; - installed updated firmware to the built in Broadcom 4306 wireless network adapter - got NetworkManager to work with a static ip address by manually editing the ifcfg-wlan0 file - managed to get the WPA security to work
The only problem I am left with is that there is no default route; if I set one up using: ip r a default via 10.1.1.1 dev wlan0
Then everything starts working.
If I try to add routes using the NetworkManager gui interface they dont get saved (no suprises there then! ).
I have tried creating a route-wlan0 file in /etc/sysconfig/network-scripts/ but this seems to be ignored by NetworkManager.
Since the NetworkManager GUI is almost useless, does anyone know if there are any other configuration files I can manually modify to get a default route set?
