NAME

gnutls-serv - GNU TLS test server  

SYNOPSIS

gnutls-serv [options]  

DESCRIPTION

Simple server program that listens to incoming TLS connections.  

OPTIONS

 

Program control options

-d, --debug LEVEL
Specify the debug level. Default is 1.
-h, --help
prints this help
-l, --list
Print a list of the supported algorithms and modes.
-q, --quiet
Suppress some messages.
-v, --version
prints the program's version number

 

Server options

-p, --port integer
The port to listen on.
--nodb
Does not use the resume database.
--http
Act as an HTTP Server.
--echo
Act as an Echo Server.

 

TLS/SSL control options

--priority PRIORITY STRING
TLS algorithms and protocols to enable. Unless the first keyword is "NONE" the defaults are:
Protocols: TLS1.1, TLS1.0, and SSL3.0.
Compression: NULL.
Certificate types: X.509, OpenPGP.
You can also use predefined sets of ciphersuites such as:
PERFORMANCE all the "secure" ciphersuites are enabled, limited to 128 bit ciphers and sorted by terms of speed performance.
NORMAL option enables all "secure" ciphersuites. The 256-bit ciphers are included as a fallback only. The ciphers are sorted by security margin.
SECURE128 flag enables all "secure" ciphersuites with ciphers up to 128 bits, sorted by security margin.
SECURE256 flag enables all "secure" ciphersuites including the 256 bit ciphers, sorted by security margin.
EXPORT all the ciphersuites are enabled, including the low-security 40 bit ciphers.
NONE nothing is enabled. This disables even protocols and compression methods.
Special keywords:
"%UNSAFE_RENEGOTIATION" Permits (re-)handshakes even unsafe ones.
"%PARTIAL_RENEGOTIATION" Prevents renegotiation with clients and servers not supporting the safe renegotiation extension. (default)
"%SAFE_RENEGOTIATION" will enable safe renegotiation. This is the most secure and recommended option for clients. However this will prevent from connecting to legacy servers.
To avoid collisions in order to specify a compression algorithm in this string you have to prefix it with "COMP-", protocol versions with "VERS-" and certificate types with "CTYPE-". All other algorithms don't need a prefix.
Examples:
"NORMAL"
"NORMAL:%COMPAT"
"NORMAL:!AES-128-CBC"
"NONE:+VERS-TLS1.0:+AES-128-CBC:+RSA:+SHA1:+COMP-NULL"

-g, --generate
Generate Diffie-Hellman Parameters.
--kx kx1 kx2...
Key exchange methods to enable (use gnutls-cli --list to show the supported key exchange methods).
-p, --port integer
The port to connect to.

 

Certificate options

--pgpcertfile FILE
PGP Public Key (certificate) file to use.
--pgpkeyfile FILE
PGP Key file to use.
--pgpkeyring FILE
PGP Key ring file to use.
--pgptrustdb FILE
PGP trustdb file to use.
--srppasswd FILE
SRP password file to use.
--srppasswdconf FILE
SRP password configuration file to use.
--x509cafile FILE
Certificate file to use.
--x509certfile FILE
X.509 Certificate file to use.
--x509fmtder
Use DER format for certificates
--x509keyfile FILE
X.509 key file to use.
