ethersrv-linux is an implementation of EtherSRV for Linux. It allows a Linux
computer to share its drive over Ethernet with multiple DOS clients running
EtherDFS.
Requirements:
ethersrv-linux requires a fairly recent Linux operating system to run, and gcc
to compile.
How to build:
just type 'make', then an 'ethersrv-linux' binary should appear (unless things
go wrong).
How to run:
ethersrv-linux [options] iface directory [directory2] ... [directoryN]
Note that, in order to be able to operate on ethernet sockets, ethersrv-linux
needs to have the CAP_NEW_RAW system capability. Usually this means that you
have to run it as root.
where:
'iface' is the name of the network interface you wish to hook ethersrv to
(for example eth0)
'directory' is the directory in your filesystem you wish to share (for
example /mnt/dosfs). You can mention several directories (up to
24), the first one will always be mapped to a virtual "C:" drive,
the second to "D:", etc.
available options:
-f do not daemonize the process (stay in foreground)
Notes:
* it is HIGHLY recommended to run ethersrv-linux over a FAT filesystem.
Other file systems might work, too, but FAT attributes will be unavailable
and DOS might get puzzled with upper/lower case filenames. The presence
and/or order of '.' and '..' directory entries might also end up being
unusual, possibly confusing applications that rely on the assumption that
both these entries are first in non-root directories.
* some Linux distributions treat FAT volumes in a case-sensitive way by
default. Such behavior leads to troubles when used by DOS (through
EtherDFS). I tested two Linux modules for FAT support: 'msdos' and 'vfat'.
The 'msdos' module worked consistently for me at all times. The 'vfat'
module, on the other hand, is known to interpret file names as UTF-8 on
some distributions, which makes the file system case-sensitive. To avoid
this, either use the 'msdos' module, or mount your vfat volume with an
explicit iocharset. Examples:
# mount /dev/sda2 /mnt/fat -t msdos
# mount /dev/sda2 /mnt/fat -t vfat -o iocharset=cp437
You can also create a FAT disk image and mount that. Example:
# fallocate -l 1024M fat.img
# mkfs.msdos fat.img
# mount -o loop fat.img /mnt/fat
