After more testing I have found that sending a file via scp or cat'ing through sendmail works like a champ if I go to a machine outside of the network. But seems to be a problem for the same machine when trying to go to a server connected to the same switch. OK.. maybe its the switch you say. Me too. Until I just came from putting the machines on a different switch and still having the same problem. It's also a completly different make and manufacture of switch. Also one other weird question. What is the real difference between a cable with 2 pairs and a cable with 4 pairs were 10/100 ethernet is concerned. On another server that was using a SMC/DEC card I found it would go nuts when it had a 2 pair cable, but worked Ok with a 4 pair cable. From everything I can tell, 10/100 ethernet should not care abt the extra 2 pairs.
