Hi all,
After upgrading to 2.9.1 from 2.9.0, !remote! definitions in the
network table is no longer generating the required shared-network
stanzas in /etc/dhcp/dhcpd.conf for CentOS 6.
I noticed that the man page for "networks" states the format needs to
now be !remote!<nicname>, so I have tried
site.dhcpinterfaces=eth1,!remote! eth1,!remote!eth1 and finally
eth1,!remote!<eth1> while also updating networks.mgtifname to the same
thing to no avail, I cannot get the shared network stanza to be
generated anymore in dhcpd.conf.
This all worked fine prior to the 2.9.1 upgrade. No configuration
changes were made between the 2.9.0 and 2.9.1 upgrade. Any help is
appreciated, thanks!
Here's what my current tables look like:
Site table:
"dhcpinterfaces","eth1,!remote!",,
Networks table:
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,comments,disable
"10_55_Corporate","10.55.167.0","255.255.255.0","eth0","10.55.167.1",,"10.55.167.32",,,,,,,,,,,,
