Are you going to provide consulting services -- for free -- when what the customer wants to do is not allowed because of your network filtering choices? -Mat -----Original Message----- From: Adam Rothschild [mailto:asr () latency net] Sent: Monday, November 20, 2000 8:06 AM To: nanog () merit edu Subject: Re: Operational impact of filtering SMB/NETBIOS traffic?

You'd have LOTs of complaint from me and many of my clients. Many of us log into our external gateway PDCs from foriegn locations. We have shares because we want shares.
Yikes. Isn't that what secure road-warrior VPNs are for?
You are considering killing off a whole bunch of legitimate use because some are too brain-dead to not have unintentional shares on the internet?
Intentional or not, sniffing SMB passwords and share info doesn't require much skill.
We use SMB/Samba INSTEAD of NFS because we believe SMB to be more secure.
That's like saying the electrical chair may be far more appealing to some than lethal injection. NFS and SMB are both insecure and inefficient mechanisms for file transfer over the public Internet. SMB may be the lesser of the two evils, but it's really irrelevant. Why not use ssh/sftp, or for the Unix impaired, some https-based file transfer interface, instead?

Howso? Sounds like you'd be promoting responsible usage instead. -adam
