CentOS 5 Networking :: Starting Wireless At Boot Time On SSH Box
Dec 31, 2010
I have a SSH box which is command line only and no X, this will be used remote and i'm trying to get the wireless network configured to start at boot. I'm using wpa_supplicant as the access point is secure with WPA2 At present if I send the following commands the machine will connect to the wifi and be reachable via ssh
ifup wlan0
/usr/sbin/wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf -D wext -dd -i wlan0 -B
dhclient wlan0
This does not start at boot but requires manual input of the above commands. I've just come to a complete blank on geting this to start at boot time. Also I would like to set a fixed IP for this box.

I've just installed CentOS 5.3 on my laptop and trying to connect to wireless internet connection at my home but I've found no success so far. I have a key on my laptop that turns blue when wifi is activated, but it is always red in linux so I guess I need to install some drivers, but I dont know what they are. When I use Windows, it automatically turns blue without doing anything. Also, yum doesnt work as well as its not connected to internet...

When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.

I installed and configured privoxy - everything worked nicely when I run it manually by
Quote:
/etc/init.d/privoxy start
After restarting the computer privoxy wasn't start automatically. I checked the links in /etc/rcX.d - are o.k. I installed sysv-rc-conf - shows that for runlevel 2 - 5 privoxy is running. I changed /etc/rc2.d/S20privoxy to /etc/rc2.d/S99privoxy - to start that process at the end. I installed Boot-Up Manager. Privoxy is marked for start automatically. I added in /etc/rc.local line: /etc/init.d/privoxy start
Privoxy still doesn't turn on at boot time and every time I must start it manually. Could you tell me how could I repair this ?

In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..

I would like the samba service (smb) to start on boot.
In the terminal (as root) I did:
/sbin/chkconfig smb --add
But after a reboot the samba service still doesn't start automatically. Is there something I'm doing wrong here?
-- Quick side question: Most of my experience is from debian and I'm confused as to why I have to add the /sbin path to most of my commands.

My fedora 11 (2.6.30-102) spends a long time while initializing services on
"Starting system message bus:"
---------- Post added at 08:47 PM CST ---------- Previous post was at 06:33 PM CST ----------
Auth is LDAP.
There's a 3.5 years old bug in redhat bugs database, that's still not resolved,regarding dbus trying to use ldap auth, before ldap service is started.Workaround is to change ldap config to soft binding.
3.5 years for a bug that affect enterprise users - are you there redhat?

Have just installed 5.4 64 bit on an AMD64 x2 system with 4 GB ram running ESXi4.Text based install went fine, but on reboot starting up it gets as far as 'Starting udev' and just hangs. Checking the performance in ESXi it appears to be using 100% cpu.I have left it for half an hour and it does not progress and the only thing to do is to power cycle the VM.I have searched and found a few suggestions for kernel parameters but they did not make any difference. I can't even get in to a command line as it doesn't boot up far enough.I have reinstalled it several times and also checked the MD5 of the downloaded file and all appears Ok.

I just finished installing CentOS 5.2 x86_64 on a Dell Dimension 3100 (Pentium 4 with 64-bit support). On the first boot, after completing the final config steps (firewall, SELinux, time server, etc), the boot hangs on "Starting xend:". I have completed a successful installation on another Dell machine (different processor), with the same installation options (I recorded all of the steps and followed them for the second installation).
My boot commands in grub are:
root (hd0,0)
kernel /xen.gz-2.6.18-128.el5
module /vmlinuz-2.6.18-128.el5xen ro root=LABEL=/1 rhgb quiet
module /initrd-2.6.18-128.el5xen.img

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..

I installed 8.04.3 Ubuntu into a used laptop for a friend, it was an ex business model HP I think, it installed well and wireless was no problem, if the ethernet cable was not plugged in, I could see the wireless signal indicator, it seemed to be there automatically and I could see the available networks displayed.The user has now apparently been using it a lot on ethernet cable for a month or two and wants to begin occasionally to use wireless. She says her daughter gets wireless ok in the house on visits, so I guess that the wifi is always on and available from the (BT, UK) home hub device in the house.
The user is reasonably adventurous, and it is possible that her exploration into a new machine and a new (to her) Ubuntu from previous windows use, she may have inadvertently clicked something and turned off wifi?The user is reporting that without the ethernet cable plugged in, there is no sign of wireless being recognisedA right click on the top panel network icon shows that there is 'no network available' (X sign) and a menu item exists for 'Edit Wireless networks'I have little or no experience about wifi use, so I would be grateful for comments on how I can guide the user to elegantly make use of either wifi or cabled connection

I trying to set up a LDAP server using openLDAP / db4. The server runs fine but I cannot get the client to work. Client and server are on the same machine, as for now. The problem seems to be in PAM. However I cannot start the system-config-authentication tool which should do the trick.
Environment

I just have installed FC 10 on a box that I will use as a router/firewall box. On the box I have three interfaces (eth0, eth0.704 (VLAN), and eth1). When the machine boots up, only eth0 and eth1 come up. If I run /etc/init.d/network restart, then eth0.704 will come up. If I add that command to rc.local, then all interfaces come up at boot.
I have the directive ONBOOT=yes in ifcfg-eth0.704. What would cause this vlan interface not to start at boot on the machine?

I followed the instructions that came with the 802 .11 Linux STA driver and was able to initialize my card and connect to a protected network! The instructions also tell me how to load the drivers at boot time, but I get an error when I try to run
Code:
# sh: for i in `find /lib /var -name wl.ko`; do mv $i ${i}.orig; done
The message returned is
Code:
bash: syntax error near unexpected token `do'
Upon restarting, my wireless is no longer active. My card is Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

I would like to mount a bunch of folders/shares when I start my machine up. I will be adding the mounts into my /etc/fstab folder BUT my WLAN0 only comes "up" and connects to my WAP AFTER logging in.
how I get it to start on PC boot instead of log in?
I think I need to disable network manager but I'm unfamiliar with the procedure in Fedora

I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

One of my ubuntu 10.04 boxes starts apache2 server automatically at boot. I know from the output of the command:
Code:
sudo /etc/init.d/apache2 status
I can't remember even setting that up, and I don't think it does so by default, since my other box in fact does not even have apache2 server installed. I can stop the server once I login, but is there a way to stop it from automatically starting the server, or even better, completely uninstall the daemon. I tried
Code:
sudo apt-get remove apache2
but that does not work. I guess the daemon is part of some bigger package.

I would like to stop network manager from starting up on boot. I have tried moving
Code:
/etc/init.d/network-manager stop
to rc.local and it did nothing but boot me into the CLI
I have also tried to put
Code:
sudo service network-manager stop and that did nothing also.
After I get network manager to stop on boot up. How do I make it so it will not auto connect to networks? My computer keeps on joining a different network on boot up. And I don't like this as some times I go to my banks website and I am on there network with out realizing it (because of the auto connect) Is there a way to stop this also?

I'm hoping someone knows about this one... I'm running the latest CentOS 5.4 with kernel 2.6.18-164.15.1.el5 (x86_64).When I boot the machine, it gets to the udev starting bit, hangs for like 5 minutes, then prints a message "Failed, will continue in the background." Then it boots OK after that.I tried booting again with the kernel option (from grub) "udevdebug", and what I saw when it tried again was a million messages saying it was waiting for "/sbin/pam_console_apply" to return, but I guess it wasn't returning... ;) Again, after 5 minutes, it gave up and finished booting.Now, this host is an LDAP client.
I figured that may have something to do with it as it is likely that pam_console_apply tries to make an LDAP lookup, which is wrong, because networking hasn't even started yet. If I disable LDAP (by removing ldap lookups in nsswitch.conf), I get no pam_console_apply errors from udev and it boots quickly. But that's a bummer, I need LDAP on this box, and I don't want my boot time to be 7-8 minutes. ;)Presumably before, when LDAP was enabled and it waited 5 minutes and then notified me that it will "continue in the background", that it was eventually successful after networking started. LDAP otherwise works fine on this box, just like all the other servers we have.This is new behavior, I've not seen it with CentOS 5.3 and below. Has anyone seen this? Any hints on what I can do to avoid it? It seems like a pam bug or something, but I don't know for sure.

I have a Fedora 11 PC, which I want to connect to the ldap server at my organisation. When my /etc/ldap.conf file is in place, the machine will not boot past "starting system messagebus" and just hangs there. I have to press the reset button, and boot it into single user mode, and remove /etc/ldap.conf, and only then will it boot. The ldap.conf file is fine, I think, because if you boot the machine up without ldap.conf, then log in.
I can put ldap.conf in place and immediately I can see all the user accounts etc. from the ldap server. If I then reboot, with ldap.conf in place, it hangs on boot again. I found a bug report for FC5 which stated this problem, but there was no solution. There was a workaround, making messagebus starting later in the boot process (move it from S22 to S27 in rc3/5.d), but that didn't help in my case.
My ldap.conf contains this (I've removed my actual ldap info):
host my.server.ip.addr
base dc=my,dc=dn
uri ldap://ldap.mydomain.com
ssl no
tls_cacertdir /etc/openldap/cacerts
pam_password md5
bind_policy soft
As I say, I think the ldap config is fine, because you can start it manually once the machine has booted up without an ldap.conf in place. I lifted it from a Centos client, which works fine and doesn't have the same problem with booting that Fedora does.
