DCC problem with 1.3.30 and solution

[Denis Beauchemin]

Hello all,

Last week-end my DCC was updated (through /etc/cron.weekly/updatedcc) to 
version 1.3.30.  After that no DCC request came through.

The problem was as follows:

    * cdcc stats
      sendto(dcc1.dcc-servers.net (2001:888:20ee::6277,6277)): Network
      is unreachable
    * or in my maillog, I had tons of:
      Mar  8 04:06:42 smtpe2 dccifd[19156]: sendto(dcc1.dcc-servers.net
      (2001:888:20ee::6277,6277)): Network is unreachable

I corrected the problem this way:

    * cdcc 'ipv6 off'
    * cd /var/dcc
    * mv dcc_conf dcc_conf.20060308
    * mv dcc_conf-new dcc_conf
    * vi dcc_conf :
      DCCD_ARGS="-4"
    * ./libexec/rcDCC restart

After that I was able to use DCC again:

    * cdcc stats
      cdcc stats
      dcc1.dcc-servers.net 208.201.249.233,512

Don't know why this happened.
