<p class=MsoNormal><span lang=EN-US>Hi,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I have a problem today and I really don’t
understand why. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’m running 4.1.0 in failover mode (also
tried 4.1.1b3). My lease time in dhcpd.conf is 86400 and everytime I
release/renew my ip from windows xp, I get a lease of 3600. I used
tcpdump/wireshark to see what’s going on and everything is fine except the lease:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US> Option: (t=51,l=4) IP
Address Lease Time = 1 hour<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
Option: (51) IP Address Lease Time<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
Length: 4<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>
Value: 00000E10<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The only value of 3600 that I have in my
config is for mclt (Max Client Lead Time) and max-balance in the failover
section. If I change the mclt value to, let say, 14400, than I get a lease time
of 14400. When I return it to 3600, I get 3600… Some network are ok and receive
the 86400 lease time… The subnet declarations are identical.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>If I create a static host entry in my
config for that pc, I get the 86400 lease time. But as soon as I comment the
static entry I return to 3600 lease time.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I also noticed that when the servers are
restarting after a config change, sometime, if I release/renew at the same time
of the server restart, I get 86400. If I renew after that I return to 3600…<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I don’t remember, but I don’t think I had
this problem last week (Friday). Something to do with daylight saving time
change this weekend?<o:p></o:p></span></p>
