Problem with DHCP



  • I configure the DHCP to use static ip and a range for dynamic adress.
    When i try to connect my pc, after the fist attemp (first time is always ok  :o ) the log say:

    Jan 3 08:26:05 dhcpd send_packet: Permission denied
    Jan 3 08:26:05 dhcpd dhcp.c:1699: Failed to send 300 byte long packet over fallback interface.
    Jan 3 08:26:08 dhcpd DHCPINFORM from 192.168.1.20 via re1
    Jan 3 08:26:08 dhcpd DHCPACK to 192.168.1.20 (60:a4:4c:xxxx:xx via re1

    and i can't connect to the LAN

    if i reboot pfsense the pc can connect again…

    PS: no Captive Portal on this system...



  • After 2 days (and many pc reboot) no problem with the dhcp.
    Today LAN stop working on my pc (the only one testing the firewall)

    after a firewall reboot i can find in the dhcp log:

    Jan 5 16:30:48 dhcpd dhcp.c:1699: Failed to send 300 byte long packet over fallback interface.
    Jan 5 16:30:51 dhcpd DHCPINFORM from 192.168.1.20 via re1
    Jan 5 16:30:51 dhcpd DHCPACK to 192.168.1.20 (60:a4:zz:zz:zz:zz) via re1
    Jan 5 16:30:51 dhcpd send_packet: Permission denied
    Jan 5 16:30:51 dhcpd dhcp.c:1699: Failed to send 300 byte long packet over fallback interface.
    Jan 5 16:32:46 dhcpd DHCPINFORM from 192.168.1.20 via re1
    Jan 5 16:32:46 dhcpd DHCPACK to 192.168.1.20 (60:a4:zz:zz:zz:zz) via re1
    Jan 5 16:32:46 dhcpd send_packet: Permission denied

    :-
    could be an hardware issue?



  • Looking to the log in search of problem i found in routing.log :

    Jan 14 12:53:46 pfSense radvd[34248]: sendmsg: No buffer space available
    Jan 14 12:53:55 pfSense radvd[34248]: sendmsg: No buffer space available
    Jan 14 12:54:04 pfSense radvd[34248]: sendmsg: No buffer space available
    Jan 14 12:54:14 pfSense radvd[34248]: sendmsg: No buffer space available
    Jan 14 12:54:22 pfSense radvd[34248]: sendmsg: No buffer space available
    
    

    Don't know if this could be related  :'(

    Did you configure DHCP/RADVD on a physically disconnected interface?



  • yes… i have 2 nic for 2 separate LAN, one with the problem (some stop working) and the other disconnected (will use it in the future) but with dhcp actived

    so this is a separate problem?  ::)

    Yes, do NOT do that; radvd is super retarded when you do this. https://redmine.pfsense.org/issues/6974
