RE: [newbie] Is NFS really that bad (reality check)
Aaron, Thanks for the clarification of your question, which I think has now been answered. I'm afraid you misinterpreted my original post. I did not refer to you as a "Troll." I said it looked as if you were "trolling" (ie. fishing) for damaging information. My apologies for any offense taken. Best regards, Frank Hilliard On Sun, 10 Oct 1999, you wrote: Good morning Frank and Mike I don't appreciate being called a troll and I am actually offended by any suggestion that I might be a front for Microsoft. I put forward this question after reading the LAME guide. It specifically says: Note: Please be aware that having an NFS service available on your system can be a security risk.

RE: [newbie] Is NFS really that bad (reality check)
Good morning Frank and Mike I don't appreciate being called a troll and I am actually offended by any suggestion that I might be a front for Microsoft. I put forward this question after reading the LAME guide. It specifically says: Note: Please be aware that having an NFS service available on your system can be a security risk. Personally, I don't recommend using it. For your reference the URL for this page is http://www.ojichan.com/linux-admin/x1270.html It's the second paragraph with the nice warning finger next to it. Please contact me if you have difficulty finding it - I can confirm that at 9.38am Monday 11 October (Perth Time or WST) the URL containing the aforementioned quote was on-line. I am simply trying to find out information. I will apologise however as the quotes I gave you were not word for word accurate, in fact the post I made was some 24 hours after reading so specifics in both examples I gave in my original post were hazy. This is an error I shall endeavour not to repeat. When I get the chance I will find the correct location for the comment in the how-to. Unfortunately IE5 which I am forced to use at work crashes when accessing ftp sites. If the wording of my original posting appeared to be a troll I again apologise. I am sure we are all aware that the subtleties of language do not translate well in short posts being read by people from all over the world. I would suggest however if you encounter a statement that you believe to be inaccurate, or misquoted, you request further information from the source rather than jumping to somewhat obtuse conclusions, which do little for the sense of community characterising Linux and Linux users. This brings me to my original point, refined as I can only confirm 1 source of information at present. The author of the Linux Administration Made Easy does not recommend using nfs services? The author seems to suggest that this is due to potential security risks, however these risks are not elaborated upon. Is there anyone on this list who has experience in using nfs services, who can shed light on these security risks? Need I be overly concerned by the risks, or are these risks similar for all types of networking/file sharing systems? Thanking you in advance.

Other network file systems to consider (please take these as pointers only, I haven't had occasion to use any of them): Coda, ARLA, (and one more I've forgotten... anyone?)

Well, since grepping the NFS-HOWTO and the files in the LAME html for
those phrases ("horrible" and "problems") returns no relevant matches,
what ought you to conclude?
