changed this the comma was missing: 
print OUT $_ , "\#\ SQLNET\.AUTHENTICATION_SERVICES=\ (NTS)";

OK. Now the line prints, i wanted it to overwrite the original line but it prints to the next line maybe i need to "remember" the line number and overwrite it?
result: 
SQLNET.AUTHENTICATION_SERVICES= (NTS)
1# SQLNET.AUTHENTICATION_SERVICES= (NTS)<p>

Are the parentheses around (NTS) interpreted as "backreference" and printed before as 1 ...?

Thanks
MH
