# silcd(8)

SILC server

## NAME

silcd - SILC server

## SYNOPSIS

**silcd** **\[** -f *file* \| -d \| -D \| -x \| -h \| -F \| -C *path* \| -V **\]**

## DESCRIPTION

Silcd is a server for SILC, Secure Internet Live Conferencing network.

## OPTIONS

**-f** *FILE*   Read configuration from *FILE*

**-d**        Enable debugging (Implies -F)

**-D** *LEVEL*  Enable debug messages of level *LEVEL* and lower (Implies -F)

**-x**        Enable hexdumps (Implies -d)

**-F**        Don't fork.  Run silcd on foreground.

**-h**        Display help message

**-V**        Display version

**-C** *PATH*   Create new public key pair. See **KEY GENERATION** for options.

## LONG OPTIONS

**--config-file**=*FILE*      Same as **-f**

**--debug**=*STRING*          Same as **-d**, limit to messages \**STRING*\*

**--debug-level**=*LEVEL*     Same as **-D**

**--hexdump**               Same as **-x**

**--foreground**            Same as **-F**

**--version**               Same as **-V**

**--create-key-pair**=*PATH*  Same as **-C**

## KEY GENERATION

**-C** must be followed directly with a path to directory into which the private and public keys will be written to. When generating new key pair  for silcd (**-C**), the following extra switches apply:

**--pkcs**=*PKCS*       Set the public key algorithm of public key pair.  For example **rsa**.

**--bits**=*VALUE*      Set the length of public key pair, in bits.

**--identifier**=*ID*   Set *ID* as public key identifier.

The identifier has the format of:

UN=\<username\>, HN=\<hostname or IP\>, RN=\<real name\>, E=\<email\>, O=\<organization\>, C=\<country\>

Both UN and HN are mandatory, all the rest are optional but recommended. If no **--identifier** is used, an identifier will be created automatically.

Example:

**silcd -C /etc/silcd --identifier**="UN=foobar, HN=foo.bar.com,  RN=Foo T. Bar, E=foo@bar.com, C=FI"

## FILES

There are two configuration files for silcd:  */etc/silc/silcd.conf* for server configuration and */etc/silc/silcalgs.conf* for SIM (SILC Modules) configuration.  Do note that silcalgs.conf is only needed if cryptographic algorithms are  built as separate modules.
