Mersenne: hackerz attackerz

Dear all: This is off-topic, except in the sense that it involves the ftp server where I maintain the Mlucas software for mersenne testing Unix clients. My ftp server has suffered its first (to my knowledge) hacker penetration. I think I stopped the attack before any serious damage was done,

Re: Mersenne: hackerz attackerz

First I am not a real expert. Turning off write permission on the blanks directory is not enough. You need to turn off permission on all the subdirectories also. Use find ' ' -type d -print | xargs chown root (between the quotes are 3 spaces). From your description, it sounds like your

Re: Mersenne: hackerz attackerz

So my question to the sysadmins out there is: what's the best way to avoid this sort of thing, without installing a firewall and while still permitting ftp access? In re-reading the DEC Unix manpage for ftpd, it seems to me the weakest link is the guideline for the ~ftp/pub directory, which the

Mersenne: Manual Use of Primenet

I've got a possible glitch report regarding the manual use of Primenet which may be useful, and a couple of comments. I run Prime95 on my main PC (PII 300) which has a dialup connection to the Internet. Having been thus hooked on this project for a year, I recently added a dedicated P166 (more
