This manual page documents the nutcpc command.
nutcpc is a console-mode client for the NuFW authenticating firewall.
It sends authentication packets to the nuauth server. All parameters
can be set on commandline but nutcpc can also be configured via the
Original packaging and informations and help can be found from
-d Debug mode, don't go into background.
-l Do not verify whether lock file exists before starting. And do
not create lock file.
-k Kill existing instances of the program running on our local
-c Check if a client is already running. Return error if no client
-V Issues program version and exits.
-h Issues usage details and exits.
-q Do not display running nutcpc options on "ps". Useful when using
-H Nuauth IP
Send authentication packet to Nuauth IP.
-p Nuauth port
Send authentication packet to Nuauth port.
-U User ID
Set nufw userid to User ID.
-P User Password
Set nufw password to User Password.
Set connection list refresh interval to Interval. This option is
only useful if nuauth server is in POLL mode.
Set kerberos service name to Service.
Use certificate file stored in the file CertFile to negotiate
the TLS connection to nuauth.
Use authority file stored in AuthorityFile and check the
validity of nuauth certificate against this authority. Nutcpc
will leave if this is not the case.
Use key file stored in the file KeyFile to negotiate the TLS
connection to nuauth.
Use the passphrase CertPass to decrypt the certificate. Check
the -q option if you use this.
Use certificate revocation list file stored in the file CrlFile
to negotiate the TLS connection to nuauth. nutcpc reloads this
file if it gets disconnected from nuauth and needs to reconnect.
Since version 2.2.19, nutcpc reloads the CRL file when receiving
a HUP signal.
Verify that the certificate given by nuauth has a DN equal to
NuauthDN. Nutcpc will leave if this is not the case.
-Q Suppress warning if no certificate authority is configured.
-N Suppress error if server FQDN does not match certificate CN.
By default, the lock file set by nutcpc is at ~/.nufw/nutcpc.
User authentication can be done using a certificate and a private key.
Such a method will be used, if nutcpc can find a certificate at
~/.nufw/cert.pem and the corresponding private key at ~/.nufw/key.pem.
The server identity will be checked if a CA certificate is provided in
~/.nufw/cacert.pem. Certificates and key can also be provided on
command line or via nuclient.conf(5).
HUP When receiving this signal, nutcpc attempts to immediately
reconnect to the server, if disconnected. The signal is ignored
in other cases.
