Oops, missed one detail in my previous posting about tuning. If/when you tune NHBUF, it should be a power of 2; ie, 128, 256, 512, 1024, etc. Thanks to those that reminded me about this, -- Frank McGee, AT&T Entry Level Systems Support attmail!fmcgee (preferred) att!cuuxb!fmcgee (those that can't reach attmail)
