This is all with nntpcache-1.0.1. First of all, I think I found a minor bug. In expire.c you call statfs and get the number of free blocks using fs.f_ffree. You should probably be using fs.f_favail. fs.f_ffree is the real number of free blocks, but does not take into account the 10% (default) free space that many file systems like to keep empty to keep disk performance high. Second; I've made a minor modification to the above code to make it call quotactl() as well. This allows me to set a quota for the nntpcache program to make sure that it doesn't use more space then I want to allocate for it. I can't use the suggested approach of having a seperate filesystem for the cache because my Unix machine is located about 3000 miles away from me, making it hard to do things like add new disks. If anyone is interested in my quota code let me know and I'll email it in. Thirdly, there were some build problems on my machine (NetBSD 1.0). You define MIN() and MAX() macros in nntpcache.h, but these are also defined in sys/param.h. I just took them out of nntpcache.h and made nntpcache.h include sys/param.h. Finally, the crux of my message. It doesn't appear that articles or XOVER lines are getting cached on my machine. Under /usr/local/var/nntpcache there are the following files: -rw-r--r-- 1 news news 0 Jan 29 15:57 cache.history -rw-r--r-- 1 news news 61 Jan 29 15:57 cache.history.dir -rw-r--r-- 1 news news 0 Jan 29 15:57 cache.history.pag drwxr-xr-x 4 news news 512 Jan 29 15:58 news.dhp.com./ -rw-r--r-- 1 news news 6 Jan 29 15:57 nntpcache.pid.DEFAULT:119 news.dhp.com./ has the heirarchy for the newsgroups that I've read, but the directories under there don't contain any information. I've checked syslog reports (I syslog everything, including debug and haven't noticed anything out of the ordinary. This isn't a bug in my quota code, because it happens even when I use the existing statfs code. I assume I should at least have the cache.mmap file (or whatever its called). Other then this, its working great as a proxy server. Its doing a fine job of replacing dnntpd, which was my previous (much slower) proxy server. Any ideas? alex
