[Bug 247584] New: dhcpcd sends DISCOVER before interface is up
https://bugzilla.novell.com/show_bug.cgi?id=247584 Summary: dhcpcd sends DISCOVER before interface is up Product: openSUSE 10.2 Version: Final Platform: x86-64 OS/Version: Linux Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: luizluca@gmail.com QAContact: qa@suse.de Hello, In a Broadcom NIC, dhcpcd sends its Discover package before interface is ready. I checked this using wireshark. Just the second Discover is correctly sent. This way, the startup script backgrounds dhcp. This way, any process that depends on network fails as ntp, autofs and so.

Either this is the job of the driver, or there is a place in sysconfig which waits for the link (I don't know, but I assume so). Christian knows more about this from the sysconfig point of view. In the end, if the link detection does not work correctly, it could be a driver issue. Christian, could you tell us how it normally works, please? There is a possible workaround by increasing DHCLIENT_TIMEOUT in /etc/sysconfig/network/dhcp: ## Type: integer ## Default: 0 # # Some interfaces need time to initialize. Add the latency time in seconds # so these can be handled properly. Should probably set per interface rather than here. # DHCLIENT_SLEEP="0" -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

DHCLIENT_SLEEP won't help cause it sleeps before dhcpcd and the link gets down when dhcpcd is running. Also changing DHCLIENT_TIMEOUT didn't help, even for huge values (99999). I think that it is a problem with the driver. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Maybe the device is broken.

After the dhcp finally gets the config or if I use fixed addresss, everything works perfectly. Maybe the device takes some time to detect the media type. I run it in a 100Mb/s network but the NIC is capable of 1000Mb/s.
