Debu messages in ISC???

[ameen.shajahan at wipro.com]

Hi Edward,

                I have DHCP conf file(dhcpd.conf) in /etc/ path with log-facility local7;   option enabled.

                And i have run the dhcp server as mentioned below
./dhcpd -4 -cf /etc/dhcpd.conf -lf /var/db/dhcpd.leases eth0  (with no -d option).So it write all the debug messages to /var/log/messages.
But i need the debug messages tp print in  separate file called /var/log/dhcpd.log.
So i have done some change in /etc/syslog.conf file with  local7.*   /var/log/dhcpd.log
But  still dhcp server writing the debug messages to /var/log/messages.

So i would like to know how to redirect to our own file.
Please let me know.

Thanks,
Ameen S

Hello,
       If I am not mistaken you can tell the conf file what file and where to put the debug info. By default it goes into messages.

*         -p <portnum> - Specify the udp port number on which dhcpd should listen. The default is port 67. The DHCP server transmits responses to the DHCP clients at a port number one greater than the udp port specified. For example, if the default port 67 is used, the server listens on port 67 for requests and responses to the client on port 68. If a port is specified here and the DHCP relay agent is used, the same port on which the DHCP relay agent should listen must be specified. Refer to Section 25.2.4 DHCP Relay Agent<http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/3/html/System_Administration_Guide/s1-dhcp-configuring-server.html#DHCP-RELAY-AGENT> for details.

*         -f - Run the daemon as a foreground process. This is mostly used for debugging.

*         -d - Log the DHCP server daemon to the standard error descriptor. This is mostly used for debugging. If this is not specified, the log is written to /var/log/messages.

*         -cf <filename> - Specify the location of the configuration file. The default location is /etc/dhcpd.conf.

*         -lf <filename> - Specify the location of the lease database file. If a lease database file already exists, it is very important that the same file be used every time the DHCP server is started. It is strongly recommended that this option only be used for debugging purposes on non-production machines. The default location is /var/lib/dhcp/dhcpd.leases.

*         -q - Do not print the entire copyright message when starting the daemon.

hope this helps,

Ed DeLargy

Hi all
                In ISC dhcp-4.2.3 code , while running server(ipv4/ipv6) or relay(ipv4/ipv6)  if we enable -d(debug option) where would be the debug messages will be printed.
                Is there any separate file for storing debug message in ISC code for both IPv4 and IPv6.
                Please let me know.

Thanks
Ameen S
