Maybe, but it can be pretty convenient sometimes.

This gives me a chance to thank the people who gave me the hint to use
"/usr/bin/tty" to set certain environment variables according to the
the virtual console I log into.  The switch I settled on for .login
follows.  It works perfectly; logging in via [Ctrl]+F3 (netbsd/pc98)
automatically sets things up to do kana-kanji conversion:

if ("`/usr/bin/tty`" == "/dev/ttyv2") then
 /usr/local/bin/canuum -Uu
else if ("`/usr/bin/tty|sed 's/\/dev\/ttyp[0-4]/p/'`" == "p") then

# If you've got a better idea, send it this way.  TIA.

 echo ""
 echo -n "         Input Japanese? (Y/N): "
 set yesno=$<
 if ("$yesno" == "y" || "$yesno" == "Y") then
  /usr/local/bin/canuum -Uu
 endif
endif

Not at all.  I do simultaneous logins to a couple of my machines via
telnet and serial consoles.

I hope someone answers this because while I am not worried about a second
mr.bean, I do run a public access guest account, and would like to limit
the (telnet) logins at any one time to about 20.  How is this done?
