perfused -- PUFFS Enabled Relay to FUSE Daemon SYNOPSIS
perfused [-fs] [-d types] [-i -fd] DESCRIPTION
perfused is a userland daemon implementing the FUSE kernel level API. It creates a /dev/fuse socket for FUSE file system daemons to connect to. perfused takes care of mounting the file system using puffs(3). When the kernel sends a puffs(3) operation for the mounted file system, perfused will translate it into a FUSE request, and will send it to the file system daemon through /dev/fuse. The FUSE reply will be converted back into a puffs(3) reply and will be relayed to the kernel. FUSE file system daemons must be modified so that they request perfused to perform the mount(2) system call instead of doing it on their own. This is done by replacing mount(2) and the open(2) calls for /dev/fuse with perfuse_mount() and perfuse_open(), respectively, in their sources. libperfuse(3) must be used at link time. Most FUSE file system daemons use libfuse and will work unmodified, provided the modifi- cation is done in libfuse itself . The following options are available: -d types Print additional debug information. types is a comma-separated list of information types to print: puffs Display PUFFS requests and replies. fuse Display FUSE requests and replies. dump Dump content of FUSE frames. fh Display file handle activity. reclaim Display reclaim activity. readdir Display readdir activity. requeue Display requeue activity. sync Display dirty flags and sync operations. -f Do not fork, but stay in the foreground. -i fd Do not open /dev/fuse but use the socket available from the file descriptor fd. This is used when perfused is started from libperfuse(3). -s Enable debug output only when receiving SIGINFO. SIGNALS
SIGINFO If the -s flag was used, toggle debug output. Do nothing otherwise. SIGUSR1 Toggle FUSE operation dump on and off. When toggling off, the trace is is stored in /var/run/perfuse-xxx.trace (xxx is the filesys- tem mount point). ERRORS
The program logs to the syslog daemon as facility ``daemon''. For detailed debugging use the -d (debug) option. SEE ALSO
mount(2), perfuse_mount(3), puffs(4) AUTHORS
The program was written by Emmanuel Dreyfus <>. BUGS
When perfused runs in the foreground (using the -f flag), some processes using the FUSE file system will sometime hang on 'uvn_fp2'. BSD

xmount - Tool to crossmount between multiple input and output harddisk image files SYNOPSIS
xmount [[fopts] [mopts]] <ifile> [<ifile> [...]] <mntp> DESCRIPTION
xmount allows you to convert on-the-fly between multiple input and output harddisk image types. xmount creates a virtual file system using FUSE (Filesystem in Userspace) that contains a virtual representation of the input image. The virtual representation can be in raw DD, Vir- tualBox's virtual disk file format, Microsoft's Virtual Hard Disk Image format or in VmWare's VMDK file format. Input images can be raw DD, EWF (Expert Witness Compression Format) or AFF (Advanced Forensic Format) files. In addition, xmount also supports virtual write access to the output files that is redirected to a cache file. This makes it possible to boot acquired harddisk images using QEMU, KVM, VirtualBox, VmWare or alike. OPTIONS
fopts: (Options specific to FUSE) -d: Enable FUSE's and xmount's debug mode. -h: Display this help message. -s: Run single threaded. -o no_allow_other: Disable automatic addition of FUSE's allow_other option. -o <fmopts> : Specify fuse mount options. Will also disable automatic addition of FUSE's allow_other option! INFO: For VMDK emulation, you have to uncomment "user_allow_other" in /etc/fuse.conf or run xmount as root. mopts: (Options specific to xmount) --cache <file> : Enable virtual write support and set cachefile to use. --in <type> : Specify input image type. Type can be "dd" or "ewf". --info : Print out some infos about used compiler and libraries. --out <type> : Specify output image type. Type can be "dd", "vdi", "vhd", "vmdk(s)". --owcache <file> : Same as --cache <file> but overwrites existing cache. --rw <cache_file> : Same as --cache. --version : Same as --info. INFO: Input and output image type defaults to "dd" if not specified. ifile: Input image file. If you use EWF files, you have to specify all image segments! (If your shell supports it, you can use .E?? as file extension to specify them files) mntp: Mount point where virtual files should be located. BUGS
Hopefully none. If you find any, please e-mail to <>. EXAMPLE
To xmount an EWF image from your acquired disk as a raw DD image under /mnt, use the following command: xmount --in ewf ./acquired_disk.E?? /mnt To xmount the same ewf image as vdi file, you would use a command like this: xmount --in ewf --out vdi ./acquired_disk.E?? /mnt And to enable virtual write support on a raw DD input image xmounted as VDI file: xmount --out vdi --cache ./acquired_disk.cache ./acquired_disk.dd /mnt Gillen Daniel May 9, 2012 xmount(1)
