DESCRIPTION
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
file nuclient.conf(5).
Original packaging and informations and help can be found from http://www.nufw.org/
OPTIONS
-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 userID.
-c Check if a client is already running. Return error if no client are running.
-V Issues program version and exits.
-h Issues usage details and exits.
-q Do not display running nutcpc options on "ps". Useful when using "-W"
-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.
-I Interval
Set connection list refresh interval to Interval. This option is only useful if nuauth server is
in POLL mode.
-Z Service
Set kerberos service name to Service.
-C CertFile
Use certificate file stored in the file CertFile to negotiate the TLS connection to nuauth.
-A AuthorityFile
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.
-K KeyFile
Use key file stored in the file KeyFile to negotiate the TLS connection to nuauth.
-W CertPass
Use the passphrase CertPass to decrypt the certificate. Check the -q option if you use this.
-R CrlFile
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.
-a NuauthDN
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.
LOCK FILE
By default, the lock file set by nutcpc is at ~/.nufw/nutcpc.
CERTIFICATE AUTHENTICATION
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).
SIGNALS
HUP When receiving this signal, nutcpc attempts to immediately reconnect to the server, if
disconnected. The signal is ignored in other cases.
