 Posted: Sat Dec 15, 2007 1:26 am Post subject: [SOLVED] Internet questions |
 |
|
So, first of all, when I boot up, I get the following, when trying to get internet.
Device initiated servbices: ipw net.eth0
Starting lo
Bringing up lo
Starting eth0
Configuration not set for eht0 - assuming DHCP
Bringing up eht0 dhcp
Running dhcpcd ...
Error, eth0: timed out
Now what I would like to happen on bootup is:
1. check to see if an ethernet cable is plugged in. If there is, connect via that.
2. Otherwise, if MyHomeNetwork is available, connect to it. Else, connect to the strongest accessible wireless network available.
Also, at the present time, after booting up, I must su into root and get internet working by doing the following (ps. I'm a noob, so maybe I don't need to do this, but as of now, this is what I did today upon booting up to get internet):
iwconfig [put in my network settings, like essid, key [1] .... etc]
/etc/init.d/net.eth1 stop
iwconfig [put in my network settings, like essid, key [1] .... etc]
dhcpcd -d eth1
/etc/init.d/net.eth1 start
How can I simply have internet, or at least start it, without having to do all that, and without having to be root to do it?
Thanks!

| Code: | | emerge sys-apps/ifplugd |
This is a utility that "Brings up/down ethernet ports automatically with cable detection". This will take care of step one.
Step two, I use wpa_supplicant, and I have my home network a higher priority, so that is looked for first. If that is not found, I have an open network setup ( in /etc/wpa_supplicant/wpa_supplicant.conf) that will connect to any open signal. I am not sure about signal strength, but I thought the wireless driver would connect to the strongest frist.

OK, so I've emerged ifplugd, but do I need to do anything else, or will it just do it automatically?
Secondly, I am using wireless-tools because my family's wireless is WEP. i attempted, in the summer, to get WPA working, but I couldn't get Gentoo to work with WPA, nor could I get another Windows machine in my house to work with WPA. So if anyone who uses wireless-tools can help me out, that would be great.
Any more help with the bootup crud would be helpful.  |

Emerging ifplugd is all you need to do for automatic cable detection. So starting/stopping eth0 will be automatic. I myself have not worked out how to start / stop wireless (my ath0) based on a cable connection. I am sure it can be done, I have not worked through it yet.
A link in this fourm for getting wpa_supplicant working is here, http://forums.gentoo.org/viewtopic-t-623183-highlight-.html, if you choose to try.
For wireless tools, ...looking
Edit: Ok, your answers reside in /etc/conf.d/net.example
/etc/conf.d/wireless.example
man ifplugd
That should cure what ails you.

Well I tried making a wireless file, and I changed my net file a bit, but after doing that, I couldn't get wireless AT ALL. Yay for backups. As it stands, I still have to log in to my computer, su as root, then do an almost random permutation of the following commands: /etc/conf.d/eth1 start, /etc/conf.d/eth1 stop, a big long iwconfig string with my required AP info, and dhcpcd -d eth1. I DON'T want to have to do that. I'll post my files here, perhaps someone else can see why this stuff is happening...
Just to reiterate, what I want is:
Boot up my computer, log into my user, have internet ready to go without needing to su or do any crap like that
If a cable is plugged in, use it
If not, go wireless, but use Word as the preferred access point
If Word isn't available, use a different one
The following files are exactly as they are on my machine, except instead of my one-word ESSID I have here "Word" and my key is the same digits as on this page, just a different string of numbers. The hyphens are exactly as in the file as well.
Current net file:
| Code: |
#-----------------------------------------------------------------------------
# WIRELESS (802.11 support)
# Wireless can be provided by iwconfig or wpa_supplicant
# iwconfig
# emerge net-wireless/wireless-tools

# Consult the sample file /etc/conf.d/wireless.example for instructions
# iwconfig is the default

# HOW TO USE THIS ESSID VARIABLE
# You can also override any settings found here per ESSID - which is very

config_Word=( "dhcp" )
dhcpcd_Word="-t 10"
# This blank configuration will automatically use DHCP for any net.*

config_eth1=( "dhcp" )
# Prefer iwconfig over wpa_supplicant
modules=( "iwconfig" )
# If you have more than one DHCP client installed, you need to specify which
# one to use - otherwise we default to dhcpcd if available.
modules=( "dhcpcd" ) # to select dhclient over dhcpcd
# Configure WEP keys for Access Points called ESSID1 and ESSID2
# You may configure up to 4 WEP keys, but only 1 can be active at
# any time so we supply a default index of [1] to set key [1] and then
# again afterwards to change the active key to [1]
# We do this incase you define other ESSID's to use WEP keys other than 1
#
# Prefixing the key with s: means it's an ASCII key, otherwise a HEX key
#
# enc open specified open security (most secure)
# enc restricted specified restricted security (least secure)
key_Word="[1] 1234-5678-90 key [1] enc open"
#key_ESSID2="[1] aaaa-bbbb-cccc-dd key [1] enc restricted"
# The below only work when we scan for available Access Points
# Sometimes more than one Access Point is visible so we need to
# define a preferred order to connect in
preferred_aps=( "Word" )
ifplugd_eth1="..."
ifplugd_eth1="--api-mode=wlan"
dhcp_eth1="nodns nontp nonis"

The following is the net file I tried to play with, but I lost my connect after using it AND a created "wireless" file.

preferred_aps=( "Word" )
ifplugd_eth1="..."
ifplugd_eth1="--api-mode=wlan"
#dhcp_eth1="nodns nontp nonis"
# This tells the dhcp client to release it's lease when it stops, not to
# overwrite dns, ntp and nis settings, not to set a default route and not to
# send the current hostname to the dhcp server and when it starts.
# You can use any combination of the above options - the default is not to
# use any of them.
dhcp_eth1="release nodns nontp nonis nogateway nosendhost"
#-----------------------------------------------------------------------------
# Cable in/out detection
# Sometimes the cable is in, others it's out. Obviously you don't want to
# restart net.eth0 every time when you plug it in either.
#
# emerge sys-apps/ifplugd
# and you're done :)

The following is gleaned from wireless.example. I looked at that file, made changes, and called it wireless. Before making a "wireless" file, there was only a wireless.example file, no wireless file.

NEW QUESTION, SAME TOPIC, SAME PERSON ASKING:
Hi,
So after a bunch of fiddling and observing patterns and such, I'm knocking my head against the wall, because here is how I can successfully get internet on my box:
1. log in
2. su as root
3. iwconfig [my settings]
4. press the refresh button on the browser a bunch of times (or once) til the page pops up
So is the reason internet takes a bit to come up for me (after entering my settings) because Gentoo has to take a second to notice my wireless AP? (Even though I'm sitting right beside my router)
Next question is: I want internet to be ready to go when I log in to my account. How can avoid having to su and running my iwconfig options? I've edited my net file, but that isn't doing it, so is there another way around this? Can I add the command as a command to run at boot? (Remember, though, that I must be root to execute the command in the first place) |
