DHCP server fail with error in config



  • I am using a 6/4 snapshot and everything was going fine (configured two WANs, 1 LAN, 1 WLAN) until I rebooted. I could not get any dhcp address and I found the following:

    When I log into the console, the WLAN interface address does not show:

    *** Welcome to pfSense 2.0-BETA2-pfSense (i386) on lanner_pfsense ***
    
      WAN (wan)                 -> em3        -> 192.168.2.197 (DHCP)
      LAN (lan)                 -> em2        -> 192.168.10.1
      WAN2 (opt1)               -> em4        -> NONE (DHCP)
      WLAN (opt2)               -> ath0_wlan0 -> NONE
    
    

    I set my ip address manually on my machine and I am still able to get to 192.168.10.1. Checking the system logs, I get the following message:

    php: /system_gateways_edit.php: The command '/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /var/dhcpd/etc/dhcpd.conf em2 ath0_wlan0' returned exit code '1', the output was 'Internet Systems Consortium DHCP Server V3.0.7 Copyright 2004-2008 Internet Systems Consortium. All rights reserved. For info, please visit http://www.isc.org/sw/dhcp/ /var/dhcpd/etc/dhcpd.conf line 23: expecting numeric value. subnet netmask ^ Configuration file errors encountered -- exiting'
    

    Inspecting the dhcpd.conf file, I see the problem:

    option ldap-server code 95 = text;
    option domain-search-list code 119 = text;

    }

    Do you see any errors on the console at boot-time about missing functions?



  • No, I didn't see any missing function error messages…

    It might be because you have DHCP enabled on your wireless interface, but it has no IP address. Not sure how that might have happened.

    I see it in the config, but it is not on the console output.



  • Yeah, that's what I noticed as well but in interface statistics screen, all the information about the interface is correct.

    Status  	 up
    MAC address 	00:0b:6b:09:xx:xx
    IP address 	192.168.20.1  
    Subnet mask 	255.255.255.0

    It appears to be correct in some areas but not in others, which may indicate that certain areas aren't getting the right interface information. This is known to happen if you don't have a proper pfSense.so PHP module, hence my questioning the boot errors.

    You may just need to upgrade to a new snapshot (from today or last night) and see if it's any better.



  • I think the problem is with timing or the order of which the ip address is assigned to OPT2, wireless interface. On a fresh boot, i see the following error message.

    Jun 8 18:43:22 	miniupnpd[63897]: HTTP listening on port 2189
    Jun 8 18:43:22 	php: miniupnpd: Starting service on interface: lan
    Jun 8 18:43:22 	php: miniupnpd: Interface opt2 has no ip address, ignoring
    Jun 8 18:43:22 	php: : The command '/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /var/dhcpd/etc/dhcpd.conf em2 ath0_wlan0' returned exit code '1', the output was 'Internet Systems Consortium DHCP Server V3.0.7 Copyright 2004-2008 Internet Systems Consortium.

    Notice miniupnpd also thinks there is no ip address for opt2 but later on, it gets an address.
