I have strange net problems on my stable machine. Irc connections,
identd, xmcd etc don't work always and perfectly. Here is example how
to emulate xmcd database query with telnet.

tick:~(13)% telnet cddb.ton.tut.fi 888
Trying 193.166.80.16...
Connected to mylly.ton.tut.fi.
Escape character is '^]'.
201 mylly CDDBP server v1.0PL0 ready at Sat Jun  8 15:18:36 1996
cddb hello tomppa tick.fidata.fi xmcd v2.0PL2
200 Hello and welcome tomppa@tick.fidata.fi running xmcd v2.0PL2.
cddb query 7e0a2c0a 10 183 15823 37875 50415 66678 83428 104515 119083 138313 158238 2606
200 rock 7e0a2c0a Scorpions / Best of Scorpions Vol. 2
cddb read rock 7e0a2c0a

It should continue session like this:
210 rock 7e0a2c0a CD database entry follows (until terminating `.')
# xmcd 1.4 CD database file
# Copyright (C) 1995 Ti Kan
#
# Track frame offsets:
#       183
#       15823
#       37875
....

It works correctly with Solaris 2, BSDI, ISC SVR3, RiscOS, FreeBSD
2.1.0R, FreeBSD 2.1.0R with June 4 stable kernel, FreeBSD 2.1.0 April
12 stable with May 29 stable kernel.

It don't work with June 7 stable or stable that I supped early May.
It hangs after cddb read command.
