 Posted: Sat Aug 16, 2008 9:21 pm Post subject: is there a way to prevent an init script from backgrounding? |
 |
|
Hi Folks,
on my Laptop my wireless network starts up with that messages
| Code: |
* Bringing up interface eth1
* Starting wpa_supplicant on eth1 ... [ ok ]
* Starting wpa_cli on eth1 ... [ ok ]
* Backgrounding ... ...
* WARNING: net.eth1 not under our control, aborting
|
i figured out that the "WARNING: ..." message is because of using wpa_supplicant so i can ignore it. i got an ip (yes thats good but it takes some time) and the boot process continues with messages like "sshd would be startet when net.eth1 has started" and /etc/init.d/net.eth1 status tells me somtimes a long long time that the interface is inactive (and the interface already have an ip adress and i can query the net and use irc) and therefor no network depending daemon has been started. i think thats not the best way.
so is there a way to tell my net.* init script to wait until the interface gets an IP adress?
all interfaces are using dhcpcd for querying for ip.
the variables [set in /etc/conf.d/net ] (here for testing purposes to 60 seconds set)
| Code: | wpa_timeout_eth1=60
plug_timeout_eth1=60 |
Won't work for me
are there others i don't realize on my search in all the net.example files? (that one in conf.d and that one in the /usr/...../openrc/.... directory )
kind regards

I have a similar set up on my laptop and I don't get "not under our control" style messages.
Could you post your /etc/conf.d/net file please?
Do you have ifplugd installed?
Cheers

Hi gerdesj,
yes i have ifpluged installed but disabled for eth1.
here the /etc/conf.d/net

then

Please excuse the English comments, my surname is German but my family have been British for 500 years or so! I like the use of postup to turn on an LED in your config - good nerdy stuff.
Now, we need to get to the bottom of why your WiFi interface - eth1 takes so long to come up.
What type of card do you have?
What is the content of your wpa_supplicant.conf?
What type of router do you have?
Cheers

|
| Code: |
modules_eth1="wpa_supplicant !ifplugd"
|
The !ifplugd causes the error message not using wpa_supplicant. Then because you have turned off plug, the timeouts wont work.
You are using OpenRC so the example file is in /usr/share/doc/openrc/net.example (I symlink it back to /etc/conf.d/net.example on all my Gentoo boxes)
This might help:
| Code: |
plug_timeout="10"
# A value of 0 means wait forever.
|
So I suggest that you drop the !ifplugd and use plug_timeout="0" then its a case of fixing up wpa_supplicant.
Just in case it helps, here is my wpa_supplicant.conf:
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=2
ap_scan=1
fast_reauth=1
network={
ssid="roseandjon"
psk="xxxxxxxxxxxxx"
key_mgmt=WPA-PSK
pairwise=TKIP
scan_ssid=1
priority=1
}
network={
ssid="blueloophq"
psk="xxxxxxxxxxxxx"
key_mgmt=WPA-PSK
pairwise=TKIP
scan_ssid=1
priority=2
}
network={
ssid="gerdes"
psk="xxxxxxxxxxxxxx"
key_mgmt=WPA-PSK
pairwise=TKIP
scan_ssid=1
priority=3
}
# Final default, will connect to nearly anything
network={
key_mgmt=NONE
priority=-9999999
}
|
I have a couple of extra settings but I notice that we are both using WPA-PSK so they may help. The examples with wpa-sup0plicant are very detailed so there may be some more help there.
It is worth checking "dmesg" it when your WiFi comes up also running #wpa_cli might give some helpful information.
Cheers

sooo got bad news ... plug_timeout="0" won't work.
also get
| Code: |
# /etc/init.d/net.eth1 restart
* Bringing down interface eth1
* Stopping dhcpcd on eth1 ... [ ok ]
* Removing addresses
* Stopping wpa_cli on eth1 ... [ ok ]
* Stopping wpa_supplicant on eth1 ... [ ok ]
* Bringing up interface eth1
* Starting wpa_supplicant on eth1 ... [ ok ]
* Starting wpa_cli on eth1 ... [ ok ]
* Backgrounding ... ...
* WARNING: net.eth1 not under our control, aborting
|
the dmesg after /etc/init.d/net.eth1 restart
| Code: |
eth1: no IPv6 routers present
ADDRCONF(NETDEV_UP): eth1: link is not ready
ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
eth1: no IPv6 routers present
|
wpa_cli:
| Code: |
> status verbose
bssid=xx:xx:xx:xx:xx:xx
ssid=netz123
id=0
pairwise_cipher=TKIP
group_cipher=TKIP
key_mgmt=WPA-PSK
wpa_state=COMPLETED
ip_address=192.168.0.32
|
any more ideas?
the problem exists since using openRC ... before openRC it workes with the timeout configs ...
a found a Bug (a OLD bug ... wher the same problem exists ... ) https://bugs.gentoo.org/show_bug.cgi?id=196029
i tried every thing in the bug bot nothing workes ...
cheers

OK, using my working one as a model:
I have baselayout-2.0.0, openrc-0.2.5, wpa_supplicant-0.5.10, dhcpcd-4.0.0_rc4
Could you change your /etc.conf.d/net to something like this:
| Code: |
modules="iproute2" "dhcpcd" "wpa_supplicant"
wpa_supplicant_eth10="-Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf"
config_lan1="dhcp"
|
ie explicitly state the wpa_supplicant stuff in here. make sure your -c is correct.
Also, you do have a symlink to net.lo for net.eth1 in /etc/init.d don't you? Also net.eth1 is added to default runlevel.

Could you check to see if #etc-update has anything left to do?
In the meantime I'll try to find time to dig through this whole thread.

Based on
https://forums.gentoo.org/viewtopic-p-5090768-highlight-associatetimeout.html#5090768
I think there is no way to easily accomplish what you want to do.
Neither ifplugd nor netplug will work.
Ifplugd says:
| Quote: |
Have a look on waproamd if you need a facility to configure WEP keys before AP associations succeed
|
The home page for waproamd says
| Quote: |
waproamd is obsolete, please use wpa_supplicant instead. waproamd contains some race conditions that are impossible to fix. wpa_supplicant supersedes waproamd in almost every way.
|
and doesn't seem to support wpa
netplug only works with wired networks.
/usr/share/doc/openrc/net.example is wrong
There is no associate_timeout_<if>.
You could fix it by hacking /lib/rc/net/wpa_supplicant.sh
Look in the function wpa_supplicant_pre_start and search for
| Code: |
ebegin "Starting wpa_cli on" "${IFACE}"
start-stop-daemon --start --exec "${wpac}" \
--pidfile "/var/run/wpa_cli-${IFACE}.pid" \
-- -a "${actfile}" -p "${ctrl_dir}" -i "${IFACE}" \
-P "/var/run/wpa_cli-${IFACE}.pid" -B
if eend $?; then
ebegin "Backgrounding ..."
exit 1
fi
|
The fix would be to change that "if eend $?; then" to go into a loop waiting for association which is what the pre-OpenRC scripts. Pehaps that code could be adapted. I may look into that. |

I whipped up this patch to add associate_timeout_<iface>=<int> to /etc/conf.d/net (when using the wpa_supplicant module) where -1 = background (how it works now), 0 = infinite and any other number is the timeout.
http://www.lanfear.net/~mark/stuff/openrc_wpa_supplicant_assoc_timeout.patch
It works for me and I'm disinclined to support it. If you don't know how to apply patches you may wish to ignore it.

nice ... today i got the time to test the patch
IT WORKES!!!...
so now i only have to try to apply a similar "patch" for the net.eth0 device ... that THAT wont go in background .. or is that already in there an i only have to configure it? [edit]see below p.s.[/edit]
cheers
Gnom
p.s. my eth0 init.d script now gets an IP (with plug_timeout_eth0="0" configured) and then it tells me * WARNING: net.eth1 not under our control, aborting ... that ummm i only can say "workes" ... but it dont really lookes "good" ... i wanna get it working like the "old" way ... waiting for an ip a defined time and abort if it wont get one ... is there a way to get it working like that?
atm the restart process of both interfaces looks like that:
| Code: |
~ # /etc/init.d/net.eth0 restart
* Bringing down interface eth0
* Stopping dhcpcd on eth0 ... [ ok ]
* Stopping ifplugd on eth0 ... [ ok ]
* Removing addresses
* Bringing up interface eth0
* Starting ifplugd on eth0 ... [ ok ]
* WARNING: infinite timeout set for eth0 to come up
* received address 192.168.0.31/24
* WARNING: net.eth0 not under our control, aborting
# /etc/init.d/net.eth1 restart
* Bringing down interface eth1
* Stopping dhcpcd on eth1 ... [ ok ]
* Removing addresses
* Stopping wpa_cli on eth1 ... [ ok ]
* Stopping wpa_supplicant on eth1 ... [ ok ]
* Bringing up interface eth1
* Starting wpa_supplicant on eth1 ... [ ok ]
* Starting wpa_cli on eth1 ...
* timeout set for association on eth1: 20
* dhcp ...
* Running dhcpcd ...
eth1: dhcpcd 4.0.0-rc4 starting
eth1: hardware address = xx:xx:xx:xx:xx:xx
eth1: DUID = xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
eth1: broadcasting for a lease
eth1: offered 192.168.0.32 from 192.168.0.32
eth1: acknowledged 192.168.0.32 from 192.168.0.32
eth1: checking 192.168.0.32 is available on attached networks
eth1: leased 192.168.0.32 for 21600 seconds [ ok ]
* received address 192.168.0.32/24 [ ok ]
* Running postup ...

so is there a way to tell my net.* init script to wait until the interface gets an IP adress? |
Sorry if I interrupt your long thread, but if the quote states your problem, would this help?

Hi Tuam,
yes that helps me for stopping the ssh daemon needing both of the network interfaces up ... (i think i write about that problem in one of the first posts ... ) but i realized that some days before ... and changed it ... but that doesn't change anything about backgrounding of the init.d script.... i really _hate_ that backgrounding of the scripts ... ok the system boots faster ... but what is when it screwes up some other scripts because of the need it running? ... (my preup function would not prevent the wireless lan from getting up if the init.d script from the wired network interface is in "inactive" state ... so everytime i got 2 interface up wich getting the same IP (the dhcp is usually configured to serve both network interfaces the same ip to prevent other network stuff from getting screwed up by a different ip) => that ends in a crash that no network device or one of those (nobody knows which one is faster at the boot time) working ... so i think the best way would be to build in a function like the associate_timeout_${iface} variable wich configures the timeout/backgrounding ... default (if not configured or -1) sould be "go in background" and if configured use infinitive (if 0 [zero]) or the specified timeout ...
thats only my opinion but i think its the best way to let the user choose wich behavior he/she want.
regards
Gnom
p.s. if somebody knows where i can patch that for my own system ... please can you tell me?
thanks
