[gentoo-user] timeouts with dhcpcd 5.1

[gentoo-user] timeouts with dhcpcd 5.1

[covici]

Hi.  I had a strange problem when I emerge dhcpcd 5.1 I get a timeout
when trying to get a lease -- it says broadcasting for a lease and times
out, however when I go back to 4.0.13 everything is fine.  I even tried
toput -I "" in the command line to emulate the old behavior, but it
didn't make any difference.

Any ideas on this would be appreciated.

I'm pretty sure you can start dhcpcd with a verbose flag.

Sure can. "dhcpcd -d <ifname>" will do it. Or put 'dhcpcd_<ifname>="-d"'
in your /etc/conf.d/net to have it always show the output during boot.

Ah, splendid!

I didn't feel the need to to look up that information because I was  
sure <snark> the OP would find it in the manpage. </snark>

You know, I almost didn't click on send, because I had a fleeting
thought that you might have used that reasoning. Always go with your
first instinct, eh? :-P

However, when I put the -d, it didn't tell me anything except that
dhcpcd sent several discover packets and then said timeout, so my
original question still remains -- why a timeout with 5.1 with the same
dhcpcd.conf and no timeout with 4.0.13.

It may be a bug.  The trick is how do you establish who the bug belongs to?  
dhcpcd-5.1 or your router's firmware?

I recall similar incident with my router and an older dhcpcd version (can look 
through the M/L for a URL if you need me to) whereby the MAC address sent by 
dhcpcd was not being picked up by the router.  The router was looking for 
that info in the ID field or some such.  Having had static IP addresses for 
my LAN machines meant that my PC would not be given the reserved IP address 
and then dhcpcd would eventually time out.  My router's firmware was not 
compliant with the respective RFC that dhcpcd was upgraded to.

The fix I came up with was router specific, therefore I do not have a useful 
suggestion for your circumstances I'm afraid - other than:

Try static IP address for your machine (use ifconfig to set this up and route 
to set up the gw).

Try using a different dhcp client to see if the problem persists.

Try updating your router's firmware just in case.

File a bug for dhcpcd-5.1 with your findings.

PS.  Other than testing is there a reason why you don't use a stable dhcpcd 
version?

I am using unstable generally, so it just came in the update.  I have no
router, this is FIOS from Verizon.

Sorry if this is a dumb question, but presumably the interface is an  
ethernet card, right? What's it connected to?

FISO sounds all very new & "experimental" and with the potential for  
not every glitch to be discovered yet. Can you beg borrow or steal a  
router from somewhere, connect your computer to that, instead, and see  
if dhcpcd 5.1 receives a lease from it? (Or alternatively, set up  
dhcpd on another machine, connect them together with a cable and see  
if that machine responds to the requests of dhcpcd 5.1)

Not sure I can get another router or another dhcp server, and it is an ethernet card.  One interesting
thing is that 4.0.13 gives the ethernet address whereas 5.1.0 does not.
