Each line in this file specifies a disabled protocol name. The following are some examples:

tcp
udp

At program start, if there is a disabled_protos file in the global configuration folder, it is read first. Then, if there is a disabled_protos file in the personal configuration folder, that is read; if there is an entry for a protocol set in both files, the setting in the personal disabled protocols file overrides the setting in the global disabled protocols file.

When you press the Save button in the “Enabled Protocols” dialog box, the current set of disabled protocols is written to the personal disabled protocols file.

When Wireshark is trying to translate an hardware MAC address to a name, it consults the ethers file in the personal configuration folder first. If the address is not found in that file, Wireshark consults the ethers file in the system configuration folder.

This file has the same format as the /etc/ethers file on some Unix-like systems. Each line in these files consists of one hardware address and name separated by whitespace. The digits of hardware addresses are separated by colons (:), dashes (-) or periods(.). The following are some examples:

ff-ff-ff-ff-ff-ff    Broadcast
c0-00-ff-ff-ff-ff    TR_broadcast
00.2b.08.93.4b.a1    Freds_machine

The settings from this file are read in when a MAC address is to be translated to a name, and never written by Wireshark.

Wireshark uses the entries in the hosts files to translate IPv4 and IPv6 addresses into names.

At program start, if there is a hosts file in the global configuration folder, it is read first. Then, if there is a hosts file in the personal configuration folder, that is read; if there is an entry for a given IP address in both files, the setting in the personal hosts file overrides the entry in the global hosts file.

This file has the same format as the usual /etc/hosts file on Unix systems.

An example is:

# Comments must be prepended by the # sign!
192.168.0.1 homeserver

The settings from this file are read in at program start and never written by Wireshark.

When Wireshark is trying to translate an IPX network number to a name, it consults the ipxnets file in the personal configuration folder first. If the address is not found in that file, Wireshark consults the ipxnets file in the system configuration folder.

An example is:

C0.A8.2C.00      HR
c0-a8-1c-00      CEO
00:00:BE:EF      IT_Server1
110f             FileServer3

The settings from this file are read in when an IPX network number is to be translated to a name, and never written by Wireshark.

At program start, if there is a manuf file in the global configuration folder, it is read.

The entries in this file are used to translate MAC address prefixes into short and long manufacturer names. Each line consists of a MAC address prefix followed by an abbreviated manufacturer name and the full manufacturer name. Prefixes 24 bits long by default and may be followed by an optional length. Note that this is not the same format as the ethers file.

Examples are:

00:00:01        Xerox   Xerox Corporation
00:50:C2:00:30:00/36      Microsof        Microsoft

The settings from this file are read in at program start and never written by Wireshark.

This file contains your Wireshark preferences, including defaults for capturing and displaying packets. It is a simple text file containing statements of the form:

variable: value

At program start, if there is a preferences file in the global configuration folder, it is read first. Then, if there is a preferences file in the personal configuration folder, that is read; if there is a preference set in both files, the setting in the personal preferences file overrides the setting in the global preference file.

If you press the Save button in the “Preferences” dialog box, all the current settings are written to the personal preferences file.

This file contains GUI settings that are specific to the current profile, such as column widths and toolbar visibility. It is a simple text file containing statements of the form:

variable: value

It is read at program start and written when preferences are saved and at program exit. It is also written and read whenever you switch to a different profile.

This file contains common GUI settings, such as recently opened capture files, recently used filters, and window geometries. It is a simple text file containing statements of the form:

variable: value

It is read at program start and written when preferences are saved and at program exit.

Wireshark uses the services files to translate port numbers into names.

At program start, if there is a services file in the global configuration folder, it is read first. Then, if there is a services file in the personal configuration folder, that is read; if there is an entry for a given port number in both files, the setting in the personal hosts file overrides the entry in the global hosts file.

An example is:

mydns       5045/udp     # My own Domain Name Server
mydns       5045/tcp     # My own Domain Name Server

The settings from these files are read in at program start and never written by Wireshark.

Wireshark uses the ss7pcs file to translate SS7 point codes to node names.

At program start, if there is a ss7pcs file in the personal configuration folder, it is read.

Each line in this file consists of one network indicator followed by a dash followed by a point code in decimal and a node name separated by whitespace or tab.

An example is:

2-1234 MyPointCode1

The settings from this file are read in at program start and never written by Wireshark.

Wireshark uses the subnets files to translate an IPv4 address into a subnet name. If no exact match from a hosts file or from DNS is found, Wireshark will attempt a partial match for the subnet of the address.

At program start, if there is a subnets file in the personal configuration folder, it is read first. Then, if there is a subnets file in the global configuration folder, that is read; if there is a preference set in both files, the setting in the global preferences file overrides the setting in the personal preference file.

Each line in one of these files consists of an IPv4 address, a subnet mask length separated only by a “/” and a name separated by whitespace. While the address must be a full IPv4 address, any values beyond the mask length are subsequently ignored.

An example is:

# Comments must be prepended by the # sign!
192.168.0.0/24 ws_test_network

A partially matched name will be printed as “subnet-name.remaining-address”. For example, “192.168.0.1” under the subnet above would be printed as “ws_test_network.1”; if the mask length above had been 16 rather than 24, the printed address would be “ws_test_network.0.1”.

The settings from these files are read in at program start and never written by Wireshark.

Wireshark uses the vlans file to translate VLAN tag IDs into names.

If there is a vlans file in the currently active profile folder, it is used. Otherwise the vlans file in the personal configuration folder is used.

Each line in this file consists of one VLAN tag ID and a describing name separated by whitespace or tab.

An example is:

123     Server-LAN
2049    HR-Client-LAN

The settings from this file are read in at program start or when changing the active profile and are never written by Wireshark.
