What you'll need to get Wireshark up and running ...
1.2.1. General Remarks
The values below are the minimum requirements and only
"rules of thumb" for use on a moderately used network
Working with a busy network can easily produce huge
memory and disk space usage! For example: Capturing on a fully saturated
100MBit/s Ethernet will produce ~ 750MBytes/min! Having a fast processor,
lots of memory and disk space is a good idea in that case.
Wireshark won't benefit much from Multiprocessor/Hyperthread
systems as time consuming tasks like filtering packets are single threaded.
No rule is without exception: during an "Update list of packets in real
time" capture, capturing traffic runs in one process and dissecting and
displaying packets runs in another process - which should benefit from two
1.2.2. Microsoft Windows
Windows 2000, XP Home, XP Pro, XP Tablet PC, XP Media
Center, Server 2003, Vista or Windows 2008 (XP Pro recommended)
32-bit Pentium or alike (recommended: 400MHz or greater),
64-bit processors in WoW64 emulation - see remarks below
128MB RAM system memory (recommended: 256MBytes or more)
75MB available disk space (plus size of user's capture
files, e.g. 100MB extra)
800*600 (1280*1024 or higher recommended) resolution with
at least 65536 (16bit) colors (256 colors should work if Wireshark is
installed with the "legacy GTK1" selection of the Wireshark 1.0.x releases)
Older Windows versions are no longer supported because of
None of the developers actively use those systems any longer which
makes support difficult.
The libraries Wireshark depends on (GTK, WinPCap, ...) are also dropping support
for these systems.
Microsoft also dropped support for these systems.
Windows 95, 98 and ME will no longer work with Wireshark.
The last known version to work was Ethereal 0.99.0 (which includes
WinPcap 3.1). You can get it from http://ethereal.com/download.html.
According to this
bug report, you may need to install Ethereal 0.10.0 on some
BTW: Microsoft no longer supports 98/ME since July 11, 2006!
