And on top of that for support of noncentralized LANs (the normal consulting role) you need to either repeat the solution for each location or allow virtually any IP to attempt uploads to your central server.
Particularly damning from a security and use perspective is that the necessity for file transfers is ad-hoc and erratic. This means that most sites won't need it, and when you do, you need it quickly. Taking the time to set up every LAN with FTP access when you support 50+ of them winds up being a significant time investment and may necessitate several workarounds due to special configurations (and even require new equipment if the client LANs have a limited number of forwardable ports - such as using NetGear's ISDN/DSL routers). After you have that done, you are left with another potential avenue of attack for someone attempting to crack the system. Admittedly, those are all issues which can be overcome, *given sufficient time* to work with them; but that's what most consultants don't have. What it comes down to is that in cases where I find myself needing regular access to customer's systems for file transfer, I usually wind up switching over to pcAnywhere. I don't like it, it isn't nearly as fast, but ultimately it saves them money since I don't have to battle with a lot of other reconfigurations and security issues. When I get time, I will probably start looking at the instant messaging clients concept to see if I can use that to do this; it certainly will save a lot of grief... ----- Original Message ----- From: "Fredrik Malmquist" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, 2002-05-20 11:22 Subject: Re: File Transfer with WinVNC? > > Another option is to set up a company FTP server - then you have a central > > log of all traffic back and forth.
