<p class=MsoNormal>Some specifics first. The current machine that I’ve
had the problem on is running CentOS 5.4 and dhcp-3.0.5-21. The problem
relates to IP information that is received by Nortel IP phones. The first
one was running CentOS 5.2, I believe. The dhcp server has multiple tagged
vlan interfaces on them and dhcp is being served for each interface.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve had this issue twice now. I built the
dhcpd.conf file on a Windows workstation using Notepad++. I don’t
remember if I used Notepad++ or gVim on the first file. When the phone
request a dhcp address it is getting a default route from a different subnet.
When I plug a regular workstation (in this case Windows XP) in, it receives the
correct default route information. This would lead me to think that the
phones are doing something wrong. The problem is that if I build a new
dhcpd.conf file locally on the server or pull one off another Linux box and
then modify the file natively in Linux the problem goes away. All I can
think is that there is some type of hidden data left in the file from editing
it in a text editor in Windows that is not removed when I run dos2unix against
the file. Using vim with :set list enabled, I compared the working
file and the bad file to see if anything looked out of place and I didn’t
see anything wrong. I also looked at the file using od –c and
I didn’t see anything that looked out of place.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Has seen an issue like this before? Any suggestions on
where I should look next? I just want to figure out what happened so I
can make sure it doesn’t happen again.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks.<o:p></o:p></p>
