CLAMFS(1) General Commands Manual CLAMFS(1) NAME clamfs - an anti-virus protected file system SYNOPSIS clamfs <configuration.file> DESCRIPTION This manual page documents briefly the ClamFS user-space file system. clamfs is a program that mount anti-virus protected file system into existing directory tree. Features * User-space file system (no kernel patches, recompilation, etc.) * Configuration stored in XML files * FUSE (and libfuse) used as file system back-end * Scan files using ClamAV * ScanCache (LRU with time-based and out-of-memory expiration) speeds up file access * Sends mail to administrator when detect virus Idea ClamFS is completely user-space anti-virus solution for Linux. It uses libfuse and Linux kernel module to provide file system. ClamAV is used as anti-virus scanner. Normally program (or library) uses glibc open() call to obtain file de- scriptor. Glibc calls kernel VFS to open file regardless of file sys- tem used. If file is on ClamFS file system open call from VFS is di- rected to user-space by FUSE. ClamFS calls libfuse to communicate with FUSE and through it with VFS. Internals ClamFS is split into four parts: * libfuse bindings -- used to communicate with FUSE (and with VFS through it), * ScanCache -- store (per file) results of anti-virus scanning to speed up future open() requests * ScanQueue -- queue files for scanning * clamd / libclamav bindings -- communicate with anti-virus scan- ner OPTIONS This program uses only one command line argument - configuration file name.
