General :: Set OpenWrt Routers DHCP To Give /32?

Mar 7, 2011

How can i set my OpenWrt 10.03 router to not to use 192.168.1.0/24? instead, use a /32 mask, so every client, that gets an ip from the DHCP server just can't sniff the network traffic - it would be a great security feature to safely use e.g.: FTP!

Networking :: Configure Dhcp To Give Front Numbers?

Jan 12, 2011

I setup DHCP on CentOS 5.5. My issue is whenever my client leases, the server gave the last available IP. eg. my dhcp ip range is 192.168.1.10 to 192.168.1.100, the server gave me 192.168.1.100, then 192.168.1.99 for the second machine. How to configure the dhcp to give the front numbers, eg 192.168.1.10 first, then 192.168.1.11 and so on. Then on option domain-name-servers 8.8.8.8; how can I include second nameserver ? 8.8.4.4 See below for my dhcpd.conf

General :: Convert To ASCII Format Under OpenWrt?

But theres no iconv under OpenWrt. Are there other working methods to convert a piped ( "|" ) text to only ascii format (under OpenWrt 10.03)?

General :: Check_NRPE From Ubuntu Server To OpenWRT Router - Connection Refused By Host

May 23, 2011

I am trying to monitorize an OpenWRT (Backfire 10.03, r23115) router from an Ubuntu server, but I am having some problems. I have installed Nrpe (2.12) on the remote host (OpenWRT), I have executed the program as a deamon (/usr/sbin/nrpe -d) but when I start the NRPE deamon, I don't get anything about NRPE executing netstat -at or ps -ef.I would need to install check_nrpe on OpenWRT to find out if NRPE is working, but I can't find any ipk package with it. Now, once in the monitoring host when I try to reach the remote host from the server:

/usr/local/nagios/libexec/check_nrpe -H ip_remote_host

I get: Connection refused by host

Even, trying with localhost:

/usr/local/nagios/libexec/check_nrpe -H localhost

I get the same error: Connection refused by host

I have installed Nagios Plugins and the check_nrpe plugin. I have edited the /etc/nrpe.cfg file:

allowed_hosts=127.0.0.1 ip_server

I don't exactly know if it is remote host's fault, monitoring host's fault or both.

Networking :: Go With OpenWRT DD-WRT Or Tomato?

Mar 20, 2010

My main wireless is an ActionTek DSL modem: it handles my incoming DSL, all my DHCP and DDNS, and it's a good Wifi base station throughout the house. Life is Good. I want wired access to a desktop PC upstairs: I tried a USB wireless stick, and it just isn't cutting it. I'm hoping I can use an old WRT54G wireless router, install some hew firmware, and use it as a wireless access point. I would like to plug the desktop into the WRT54G (cabled), have the WRT54G get a DHCP address and register the desktop's hostname in DDNS (wireless), and have everything work.

Q: Is "wireless access point" the correct term here?

Q: Should I go with OpenWRT (suggested in a previous post: looks very promising), DD-WRT, or Tomato?

Networking :: Which Current Model ADSL Modem Router For DD-WRT - OpenWRT Or Tomato?

Mar 25, 2010

What are the pros and cons of various current model ADSL modem routers for use with DD-WRT, OpenWRT or Tomato? There are, of course, hardware compatibility lists (HCLs) for each of these (DD-WRT, OpenWRT and Tomato) but many of the models are no longer available and there are so many that researching them all would be onerous. Many pages on the Internet recommend the WRTG54L and that would be great but it is no longer an option except second user which is increasingly difficult. What are the pros and cons of the various chipsets: ADM5120, AR7, IXP4xx and BCM63xx?

Ubuntu Networking :: DHCP Server No Longer Responses To DHCP Requests - Can't Ping Gateway

Oct 22, 2010

Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.

Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces

Code:

auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static

[code]....

why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

Networking :: Configure A (openSUSE) Client To Dhcp To EBox DHCP Server - Lease An IP Address

Mar 25, 2010

I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response

openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.

The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0

I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?

Ubuntu Servers :: DHCP Server And DHCP Client Simultaneously?

Aug 4, 2010

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.

When I now want to use this private key in a script to log on to the remote server via ssh and do something, how can I give the passphrase? Alternatively, is it possible to use a different private key without passphrase ? I doubt it, but it doesn't harm to ask.
