Slackware :: Disable Dhcp Polling For Eth0 At Boot Up?

Apr 20, 2010

During installation I set eth0 to use dhcp to get an IP address. I then installed gnome and networkmanger which handles my interfaces and works fine. But during bootup the system pauses for 5 seconds or so while it polls for dhcp. It then times out and gives me a 169.254.xx which is then replaced when networkmanager starts up at the end of bootup.

How do I stop the polling to cut out the 5 seconds?

CentOS 5 :: How To Speed Up Boot Time / Disable Or Change Eth0 At Boot / Searching?

Jan 11, 2010

This on a Vostro 1220 Laptop w/ Intel 5300 wireless:

A.I have long boot up time.I think it's because of the eth0 network search which I don't use.I have an intel wireless 5300 card running.How can I speed up the boot time, i.e. disable or change the eth0 at boot, the searching?

B:When I restart or shutdown, the screen flashes repeatedly and gets some garbled colors along the top before finally rebooting looks like windows ME or something).This vostro has an intel x4500HD vid chipset in it.

C.How do I get into gnome configuration editor to turn on Metacity compositing? Alt-F2 and run gconf-editor doesn't do it. I don't do compiz, but need compositing.

D.I need to install Chromium Browser as it sync my bookmarks.I have RPMforge enabled btw also...how can I do that? I.e. rpm repo for chromium?

This will help me get off to a running start so I can get up to speed on CentOS..

Networking :: Eth0 Fixed IP - Eth1 DHCP Gateway - Access To Eth0?

Aug 19, 2009

5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.

I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.

Code: echo !HH | nc 192.168.1.6 80

I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?

Ubuntu Networking :: Eth0 Not Coming Up Automatically With Dhcp (11.04)

pre-up iptables-restore < /etc/iptables.rules
post-down iptables-restore < /etc/iptables.rules

but eth0 doesn't automatically come up. I have to do a "ifconfig eth0 up" and then do a dhclient eth0 in order to get an IP after each reboot.

CentOS 5 Server :: DHCP Config ( No Subnet Declaration For Eth0 )?

I had a server that I use for Radius DNS and Trying to put DHCP on it I have My pool in it seems right. I have 2 adresses aliased one being a helper IP that the router will send the request to. When I try to start the dhcp server I get the following.

Programming :: Continuously Polling A Specified Key?

Nov 23, 2010

In a lot of programs I write, I would love the option to simply hit a key without disturbing the data, and have some other action take place.

An example loop would be,

Code:
for(some var = 0; some var != infinity; some var++){
if(poll(left mouse button)){ stop doing this stuff; }
.
.
.
doing other stuff, because the left mouse button wasn't pressed
}

but, I don't want the loop to pause for more than a the tiniest fraction of a second, and I certainly don't want it to sit there waiting for me to do, or not do, something.

What is it I'm looking for?

(Oh, and if you haven't guessed, c/c++ are the languages of choice for this operation - I don't care which you might have in mind when submitting an answer -- in fact, it need not be either of those languages.)

Fedora Networking :: Dns Not Working Until Disable And Reenable Eth0?

Oct 18, 2009

I've got a 64 bit home server system that was upgraded from FC2 to 7, 9, now 11. I've now got a weird situation where dns inquiries will not work when I reboot the machine, until i restart eth0. When I reboot, I can open firefox on the machine, put in the IP of my dsl router, and look at it's settings just fine. All other internet uses, whether it's yum,squid, or etc. comes back with the usual name server not found messages. I've got thenetwork setup to use the named on this server, ( the web's a tad bit slower when I set it up to use ISP's windows nameservers, go figure).

Anyway, a few years ago I set up the machine to use the network service to bring theseinterfaces up. (I believe this was because the early versions on Networkmanger had some issues. In an attempt to fix this issue I reset Networkmanger start at startup, and reset up eth0 and 1 to be controlled by it.I then got namserver1=XXX.XXX.XXX.XXX in resolve.conf at reboot..(yeah they were really X's, I'm not hiding an ip here) I tried going intonsswitch.conf, found the line hosts: files mdns4_minimal [NOTFOUND=return] dnsand changed it to:hosts:files dns mdns4_minimal [NOTFOUND=return]No joy, I still have to do an ifdown eth0 and an ifup eth0 to get dns to work..

Security :: Disable StrictHostKeyChecking For A DHCP And DNS-using Subnet

Dec 28, 2010

I have a VMware farm where:

- DHCP is in use to give machines IPs
- Machines go up and down all the time
- All IPs are on a certain subnet
- VMs update DNS (we don't go by IP)
- SSH is in use

I would like to disable StrictHostKeyChecking only for this subnet, because IPs change all the time and editing known_hosts usually only works for a few days before the IP changes again, and once I get enough entries, there are tons of conflicts.

I tried the following in ~/.ssh/config:

Code:
Host 10.0.217.*
StrictHostKeyChecking no
UserKnownHostsFile /dev/null

Red Hat :: Disable DHCP Client Requests On Rhel 5.4 64bit?

i want to disable all DHCP request, can i turn off the client that if a MAC address changes a dhcp request is not automatically made?reason for this: I have HP blade running with an Intel NC260M mezzanine card running with virtual connect. I have experienced problems with firmware levels with this card where the virtual connect mac address is ignored and the real MAC displayed. As we are using bonds on the servers and have 6 NICs installed we have to tie down the MAC address to a bond. A blade was replaced today without the firmware update and the real MAC appeared, a dhcp request was made and my-eth[2-3] and resolv.conf files were over-written by the dhcp supplied

Slackware :: New LAN Card And Eth0 Disappears

Jan 13, 2010

I have been running an IBM etherjet 100/10 card for several years in a system with the motherboard's VIA Rhine LAN disabled. But, now the etherjet went bad, eeprom corrupted error in system log, so I removeed it and enabled the VIA Rhine on the motherboard.

However, when I boot slackware 13 , smp huge kernel (I have not got around to building custom for this system), I no longer have eth0, only lo.

However, system log has:

So, why does it no appear with ifconfig? I also have a ubuntu 9.10 install on a separate partition and it detects and uses the VIA LAN in place of the old etherjet.

Slackware :: Settings For 'eth0' Go To 'pan1'?

I switch between two ip configurations, a dhcp one and another with static ip. The problem is that, when I changed the 'eth0' part of /etc/rc.d/rc.inet1.conf file to use dhcp, and restart rc.inet1, I get the original ip address unchanged in eth0 interface, and the newly gotten ip address goes to 'pan1'.I can surf the internet as usual, I have noticed this problem because I can not ping to the default gateway or use the network printer.

Slackware :: Possible Error In Rc.0 And Rc.6 With Dhcp

Slackware :: WEP 64-bit - DHCP Won't Assign IP

Jan 6, 2010

The router is set up to use a 64-bit WEP passphrase. From what I've read, that means four different hex keys. One of which is meant to be active. I've tried each of the four generated keys, one-by-one. I've also tried putting them all in and activating one, but the syntax seems to be wrong.

I read Alien's Wiki on it, and various other sources. People keep suggesting wicd, but I want it to work with the rc.inet1.conf file first. Just so I know what needs to be entered in order for that to happen. I have a desktop to set up eventually as well, and that shouldn't need wicd.

My configuration file*: [url]

My lspci entry for the wireless card:

Code:

*I've edited this several times since upload, but nothing has worked so I don't think I need to keep it up-to-date. The online file is basic configuration, I believe.

Slackware :: Static IPs From Dhcp Router?

Jul 6, 2010

My ISP provides my internet via DHCP. I have a home wireless router to provide internet access, wired for my desktop machine and wireless for my laptop. My question is: Is it possible to configure the router (the Access Point) to provide internet to the desktop and the laptop via static IP? Currently I have managed to configure the internet to them via DHCP and it works. I am just curious to know whether it is possible to provide the internet for them by static IPs, given that the internet that actually goes into the Access Point (the wireless home router), is DHCP.I fiddled with this a lot yesterday, but I only managed to get a working configuraton by DHCP for both the desktop and the laptop. If I supply them with static IPs, I can only ping the Access Point, but not beyond it. So does it at all make any sense to try to configure them by static IPs, i.e. is that virtually possible?

Slackware :: Configure System To Start Wlan0 Instead Of Eth0?

Nov 29, 2010

I'm running Slackware-13.1 on my laptop. Connection to my network is via wlan0, a cable in most cases not pluged in.When starting the system the first attempt to configure the network is via eth0, which ends with dhcpcd timing out since there is no cable pluged in. Afterwards wlan0 is set up properly.

I have installed ifplugd, which is a daemon who connects to ethernet only if a cable is connected. With Gentoo this works out of the box. With Slackware ifplugd is started after rc.inet1 (probably). So the the system still tries to connect via ethernet before connecting to the wireless network.

I have also installed wicd.How can I manage that wlan0 is prefered over eth0?I noticed that neither wicd nor ifplugd belong to the default full installation of Slackware and therefore assume, there must be a solution which meets my requirements without even one of both programs.The laptop is only used at home. Wireless connection is normaly used. I need eth0 only in a case of emergency.

Slackware :: Dhcp Fixed Address Not Working

Jun 7, 2010

I have a slackware server running ISC dhcpd and bind, and I want to give a dual boot XP / Ubuntu client a fixed address based on its MAC.

I added a host stanza to my server's dhcpd.conf:

Code:

I restarted bind and dhcpd, restarted the client's networking, and it still requests (and receives) its previously leased address, which is not the fixed address I want it to get. I tried dhclient -r to make the client release the old address, didn't help. On networking restart it still gets offered the old (wrong) address. Could it be that dhcpd somehow hangs on to the old lease even after the client sent a DHCPRELEASE?

How do I tell dhcpd to forget about an old lease, and how do I make dhcpd hand out the fixed address (and only that address) I specified for a given MAC, regardless of what the client requests?
