    System: Linux flowscan1 2.2.19pre17 #1 Tue Mar 13 22:37:59 EST 2001 i686 unknown
            Debian Linux 2.2r3 (potato)

    I've gone through the cflowd mailing list archives and seen a few threads
    related to this exact problem, however not much on a resolution.

    When I start cflowdmux, the process stays alive, but doesn't appear to be
    listening on any UDP sockets.

    Dec 10 22:56:37 flowscan1 cflowdmux[28520]: [I] cflowdmux (version
    cflowd-2-1-b1) started.
    Dec 10 22:56:37 flowscan1 cflowdmux[28520]: [I] created 1052672 byte
    packet queue shmem segment {CflowdPacketQueue.cc:247}
    Dec 10 22:56:37 flowscan1 cflowdmux[28520]: [I] attached to 1052672 byte
    packet queue at 0x4016d000
    Dec 10 22:56:37 flowscan1 cflowdmux[28520]: [I] created semaphore: id 4

    # ps aux | grep cflowdmux
    root 28520 0.0 0.2 2884 828 ? S 22:56 0:00
    /usr/local/arts/sbin/cflowdmux /usr/local/arts/sbin/cflowd.conf

    cflowd then fails to get the semaphore...

    Dec 10 23:00:23 flowscan1 cflowd[28525]: [I] cflowd (version
    cflowd-2-1-b1) started.
    Dec 10 23:00:23 flowscan1 cflowd[28525]: [E]
    semget(ftok("/usr/local/arts/etc/cflowd.conf",0),2,S_IRWXU|S_IRWXG|S_IRWXO)
    failed to get semaphore set: No such file or directory
    {CflowdPacketQueue.cc:124}
    Dec 10 23:00:23 flowscan1 cflowd[28525]: [C] failed to get semaphore!
    {CflowdPacketQueue.cc:331}
    Dec 10 23:00:23 flowscan1 cflowd[28525]: [A] failed to open packet queue!
    Exiting. {cflowd.cc:991}

    My cflowd.conf looks like this - IP addresses and AS numbers changed to
    protect the possibly-innocent ;-)

    OPTIONS {
      LOGFACILITY: local6
      TCPCOLLECTPORT: 2056
      PKTBUFSIZE: 2097152
      TABLESOCKFILE: /home/flowscan/cflowd/etc/cflowdtable.socket
      FLOWDIR: /flowdata0/flows
      FLOWFILELEN: 1000000
      NUMFLOWFILES: 10
      MINLOGMISSED: 300
    }

    COLLECTOR {
      HOST: 127.0.0.1 # IP address of central collector
      AUTH: none
    }

    CISCOEXPORTER {
      HOST: 192.168.88.14
      ADDRESSES: { 192.168.88.14 }
      CFDATAPORT: 2055
      SNMPCOMM: 'snmpcommunity'
      LOCALAS: 65535
    }

    Any ideas here would be greatly appreciated.
