My router is a DHCP Server.My Access Point is a DHCP Server.I'm wondering if it is really necessary and usefull.Is it possible to get an IP from the Router through the Access Point.For exemple I connect my laptop to the wifi Access Point and the IP is given by the router only.
I know there are tons of help guides out there for this, and I have looked at and tried them all. I am trying to do something really simple, and just can't seem to get it working. I have been trying on and off for the better part of a week now, with not much luck. What I am tyring to do is have a Ubuntu 10.10 server serve out DHCP addresses and be the DNS for the local network. The local network will have no internet access, so it only needs to know the names of the local server. My network setup is as follows:
1: Windows Vista web server 2: Ubuntu DHCP3 and BIND server to give IP's and resolve local names. 3: A bunch of tablet computers connected via dhcp to the network, that need to access the web server on the Windows machine.
I have DHCP working nicely, but it fails to propagate the hostnames to the tablet computers. Unfortunately I need this to work, as the tablets do not have the capability of having a 'hosts' file.I have tried just about every self-help guide I can find, and just can't seem to get this work. Everything seems to work fine except for the name resolution. Any help would be great, I don't have that much hair left to pull out!
I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?
For strange reasons I was stuck without an Internet connection for about 2 hours. I couldn't establish a connection, even local network only via DHCP. This was on Natty. After 30mins passed, I rebooted to Maverick only to get the same results. With nothing else to do, one hour after, I booted into Windows XP to play Dragon Wars 2. Lo and behold! I had Internet connection. At first I thought it was a technical problem with my ISP. So I rebooted hurriedly to Natty and after several minutes of trying to coax Network Manager for a damn fre*kin* connection it still couldn't.
Back again to XP, I couldn't believe that I wasn't experiencing some kind of on/off signal from my ISP. It wasn't just a coincidence that I could connect on XP and not on Natty. The connection was fine! And I've reason to believe for the past 2 hours, my ISP wasn't the culprit. .. this time it was on my end.Now - on Natty - I manually configured the connection (Instead of DHCP) to be greeted with the familiar Connection Established prompt from notify-OSD.
I've installed the Ubuntu 10.04 Server onto a PPC G4 Mac just for the experience of setting up a server. During the installation process Ubuntu couldn't auto-configure my DHCP Network. I'm using the airport card on a wireless network. How can I manually configure the network once Ubuntu is installed.
I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)
I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).
I'm trying to install Ubuntu server on an older 05-06 Desktop (IBM) and when I get to the Configuration part it stops right around 95% and the prompt reads that configuration failed do to the fact that my unit is running a non DHCP Network or my machine is two slow. Now it does only have 1 gig in it right now so I'm thinking that might be the problem also. But if it is a DHCP issue how can I install UBUNTU or is it even possible?
I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.
However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.
Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?
Does anyone know if you switch networks Where you have your servers hosted on a Non-DHCP Network, and you switch your IP addresses, then do you have to switch change/assign your new gateway address? I'm not sure if its manually assigned? How do you do it? Also what about nameserver resolving?
I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
Why I am getting this messages and more importantly how do I get rid of them.
I've followed several guides and am trying to get NFS working on my local network. For starters, I think I should be able to NFS mount a drive on the server (192.168.1.65) TO the server. From there I'll work with another client (currently 192.168.1.80)
I am setting up my first server (which will be a file server when complete). I have some experience with a terminal, but not much. I'm not at all afraid of it, and want to learn more (one of the reasons I'm doing this project). At the moment I am trying to get the server to see my network. Using the info I found here: URl... I have been able to ping the router. I cannot, however, reach other computers on the network. Nor can other computers ping the server.I am looking for a newbie guide on how to connect to my local network.
I'm attempting to run a DHCP server on my home network to enable PXE booting for ethernet clients, but I'm having quite a few issues getting it all up and running. I'm not entirely sure what is wrong, but I keep encountering errors in syslog as follows:
Feb 27 02:26:46 servnerr-1 dhcpd: Wrote 0 leases to leases file. Feb 27 02:26:46 servnerr-1 dhcpd: Feb 27 02:26:46 servnerr-1 dhcpd: No subnet declaration for eth0 (192.168.1.3).
Networking is not exactly my strong suit, but I would like to get this up and running if at all possible.
I've tried, but now I give up. I'm trying to run Apache on FC9. Nothing fancy, no extras, just the default installed apache. [correction, I have coldfusion installed, however the service is not running] I've set the Listen variable to every combination I could think of, with no success. I can set it whatever I like (such as my local IP) on any port other than port 80. If I try to set it to 192.168.x.x:80, it gives me the error message: Starting httpd: (98)Address already in use: make_sock: could not bind to address 192.168.x.x:80
I've run netstat commands to try and find applications listening on port 80 and found nothing. Whenever I chose a port other than 80 to get the service to start successfully, I am able to serve pages locally. But even with my ports forwarded correctly, no one outside the local network can see it. I've checked with nmap that my machine is opening the ports and even cheated, disabling the firewall during testing to ensure it was not part of the problem.
I noticed while locally nmaping my server that whenever I set Listen 192.168.x.x:8081, 8081 is opened, as well as normal port 80. When I stop the httpd service, both those ports are simultaneously closed. Why is httpd opening port 80? I'm assuming this is related to why I cannot assign Listen to port 80. If I run remote scans from sites like www.nmap-online.com and www.canyouseeme.org, nmap-online will report filtered on ports 80 and 8081 if my httpd is running, and if httpd stopped, 80 is closed, filtered 8081.
Can you seem reports success on ports 80 and 8081 if httpd is running, fail if httpd is stopped. I'm sure thats all a lot of information cluttered in to all that. To summarize, I cannot start my httpd server on port 80, and I cannot ever see my webpages beyond my local network. Am I missing something extremely is simple and I'm just over looking it?
The situation is this, I have one of those router cable/wifi. So I have the main pc plugged to the router, the router give local ip for all my network (the others computers connects via wi-fi). Main pc starts up apache under Fedora 12, http://localhost.. works, http://127.0.0.1.. works, http://192.168.0.13 (my local ip) works. But when I try to connect to http://192.168.0.13 from another pc of my local network, it doesn't work. The others pcs are running windows vista.
I go another computers ping 192.168.0.13, responds! From the main computer ping 192.168.0.14, responds! So, there is communication between the machines, but I cant get to work under apache. I tried opening port 80 with iptables, i tried changing apache's port to another.
I had problems with my Ubuntu Server 10.4, so I reformatted and reinstalled (I only choose OpenSSH from the install menu), then after it rebooted I installed apache. So I can access the machine via web, ssh and scp from within my local network, but strangely outside my network I can access it from web, but not ssh or scp. Nothing has changed on my router.
I've been researching this all day with no luck thus far. Basically I need to cutoff port 21/ftp access from IP addresses outside of my local network. My local IP range is something like 192.168.0.100 - 192.168.0.150 -- so anything outside of this range would automatically be blocked.
Any IP address outside of this range would be denied as I use SFTP for remote access, etc. from home, etc.
I've researched IP tables, tcp wrappers, etc. but am still unsure which would be best for what is probably a simple fix.
I am trying to setup a DNS server on my local network. When I set linux clients to use it, it works as expected. However, when I set windows clients to it, the root name doesn't resolve. For example, I have a zone called daniel. On linux "anything.daniel" resolves to the correct ip as does "daniel" which is the behavior I want. However, on windows 7, "anything.daniel" resolves correctly, but "daniel" doesn't. I am new to BIND9 so my config is mostly copy and pasted. Here is my zone file for daniel (where #.#.#.# is the ip I want daniel to resolve to):
@ IN SOA ns1.daniel. admin.daniel. ( 2007031001 28800 3600
I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.
I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
I have a lab of 10 computers with ips from 192.168.1.120 to 192.168.1.130 the server's Ip is 192.168.1.116When I am on client computer I type the server's Ip address on the browser and it works. All i want is that instead of entering my servers Ip I could just enter an address like: example.lan
i have php5 and mysql on ubuntu server which is hosting a WordPress blog. i activated it remotely over the internet and it works fine still over the internet. now im home and using my local network again and now when i try to go into it with its local IP, it just shows some text (blog title, posts and so on) with NO pictures.
I'm trying to setup a NAS for my network, the only problem is that I can't figure out how to do it. On my network I have about 3 computers however only I only use 2 of them so I thought that maybe I could use the third computer in such a way that I could access it 24/7 from the internet as a server for all of my files (school papers, music etc etc...). The only problem is that I don't know where to get started. Both of the computers I'm currently using are Windows and the one that I,hopefully, can turn into a server is running on Ubuntu.
I have public IP and registered domain mydomain.eu. On domain provider DNS servers, mydomain.eu points to my machine called solis (10.10.10.1; this is gateway, dhcp and dns server; eth0 is outsite, eth1 inside my network). I have also laptop which is connected to eth1 through wireless AP. From laptop and solis I have access to outside and inside network without problems. Of course my dream is to have access to solis from local network using name 'mydomain.eu' but not fully name 'solis.mydomain.eu'.
