but once the string is noticed, the connection is dropped. compare the string size of: 4fug4AtAnNIbg with the size of this: 28 Sep 19 MS Corporation (2182) Latest Internet Critical Upgrade which one do you think is bigger? the real question is, by how many orders of magnitude? ;-) no, i don't think so. anyway you slice it, short of a full blown DOS attack, i think a 13 byte string can be transered many times before it becomes beneficial to eat a latest internet critical upgrade. not to mention the fact that in a best case scenario, the system admin of the remote system will get an email about a frozen message being given up on. he'll go investigate and notice "ohmigosh, i have a virus!". then he'll be so disgusted with the whole virus thing, he'll go out and install linux on all the companies servers. the money they saved go into profit statements, which raise the value of their stock. people notice the stock of the company is starting to rise and they want a piece of the action. the extra cash flow leads to higher production and more income. the business starts to flourish and the hire unix system admins and programmers by the droves. in fact, the hire you. they pay you $250,000 per year to do opengl renditions of their product. all because you drop the connection after a 13 byte string gets transfered. you'd be NUTS not to do it... pete -- GPG Instructions: http://www.dirac.org/linux/gpg GPG Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
