NAME
gogoc.conf -- gogoCLIENT Configuration File SYNOPSIS
The gogoCLIENT gogoc(8) is a client program which enables a host to query a tunnel server to establish a tunnel between the host and the server using the TSP protocol. The gogoc configuration file contains information that is read by gogoc(8) for specific details regarding the server and the tunnel to be established. FILE FORMAT
This file is designed to be human readable and may be edited with any text editor. The file consists of tokens and values, which are sepa- rated by the equal sign. Each "Token=Value" pair must be on their own line. The different configuration directives(or options) are grouped in the following sections: BASIC CONFIGURATION
userid The userid is used for authentication with the server. The TSP protocol supports both anonymous and authenticated tunnels. Refer to the server policies for supported modes and related Services, as well as for how to register your user name. The syntax to use is given below: userid=user_name This variable is MANDATORY if you are using an authenticated tunnel. Leave empty if you are using anonymous access. passwd passwd=your_password Leave empty if you are using anonymous access. server Name and port number of the tunnel server. This variable is used to specify the gogoSERVER to be queried. An IPv4 or IPv6 address or FQDN (Fully Qualified Domain Name) can be used. The port number is optional. The default TSP port is 3653. server=host[:port] server=broker.freenet6.net server=192.168.1.1:3653 This variable is MANDATORY. auth_method The tunnel negotiation authentication method. If you are using anonymous access, enter `anonymous' here. Otherwise, choose one of the following authentication methods: any|digest-md5|passdss-3des-1|plain anonymous sends no username or password. any is the preferred one. The most secure mechanism common to the client and the broker will be used. digest-md5 sends the username in clear text, but not the password. passdss-3des-1 sends the username in clear text, but not the password. plain sends both username and password in clear text. Default: any ROUTER CONFIGURATION
host_type Set the value of this directive to `router' to configure the machine as a router. By doing so, you will be given a prefix to adver- tise on a local interface. host_type=host|router Default: host prefixlen prefixlen specifies the required prefix length for the gogoCLIENT network. Valid values range from 0 to 64; however, values are usually between 48 and 64. Default: 64 if_prefix if_prefix is the name of the OS interface that will be configured with the first /64 of the received prefix from the broker. The router advertisement daemon is started to advertise this prefix on the if_prefix interface. dns_server This directive specifies the DNS servers that should be used for reverse DNS delegation of the prefix allocated. Syntax is: dns_server=fqdn[:fqdn]... For example, to set ns1.example.net and ns2.example.net as authoritative DNS servers for reverse DNS of the prefix, this line would be used in gogoc.conf: dns_server=ns1.example.net:ns2.example.net NOTE: Never use an IP address as a DNS server name. ADVANCED CONFIGURATION
tunnel_mode The tunnel encapsulation mode. It can take the following values: v6anyv4 This mode lets the broker determine whether or not the gogoCLIENT is behind a NAT. The broker will then inform the gogo- CLIENT which tunnel mode to use: v6v4 or v6udpv4. v6v4 Explicitly requests an IPv6-in-IPv4 tunnel. v6udpv4 Explicitly requests an IPv6-in-UDP-IPv4 tunnel (for clients behind a NAT). This type of tunnel is supported under Linux, FreeBSD and Windows. v4v6 Explicitly requests an IPv4-in-IPv6 tunnel (for dual-stack transition mechanism). Default: v6anyv4 auto_retry_connect This directive is used when a keepalive timeout or similar error occurred, resulting in a loss of connectivity with the tunnel end- point. If you wish the gogoCLIENT to re-establish connectivity with tunnel endpoint when such an error occurs, set this variable to `yes'. auto_retry_connect=yes|no Default: yes retry_delay The retry_delay directive is used to set the number of seconds to sleep before reattempting to establish a tunnel with the gogoSERVER. It will retry until it succeeds, unless you have set the auto_retry_connect variable to `no'. Default: 30 keepalive keepalive indicates that this client will send keepalive packets to maintain tunnel activity and detect inactive tunnels (if no response is received from the server). This directive must be set to `yes' when using v6udpv4 tunnels to keep the NAT entry active. keepalive=yes|no Default: yes keepalive_interval The keepalive_interval is a suggestion from the gogoCLIENT to the broker for the interval to wait between sending keepalive mes- sages. The broker may impose a different interval value to the client if the suggested value is too low. keepalive_interval=30 Default: 30 if_tunnel_v6v4 The logical interface name that will be used for the configured tunnel (IPv6 over IPv4). The syntax is: if_tunnel_v6v4=name Under *BSD: gif0 Under Linux: sit0 Under Windows: 2 This variable is MANDATORY. if_tunnel_v6udpv4 The logical interface name that will be used for v6udpv4 tunnels (IPv6 over UDPv4). The syntax is: if_tunnel_v6udpv4=name Under FreeBSD: tun1 Under Linux: tun Under Windows: tunv6 if_tunnel_v4v6 The logical interface name that will be used for v4v6 tunnels (IPv4 over IPv6). The syntax is: if_tunnel_v4v6=name gogoc_dir The directory where the gogoCLIENT program is installed. Binaries, manual pages, this configuration file and templates are all located in this directory. This variable may resemble the following: gogoc_dir=/usr/local/gogoc This variable is MANDATORY. template This directive indicates which configuration template must be used when configuring the tunnel. The configuration template is a script file, located in the template directory of the package, that contains the system commands to be executed for tunnel setup. The directives are passed to the script file as environment variables. The template directive is normally set when the package is built for the specific operating system. View the contents of the template directory to learn which ones are available. The tem- plate name must be the file name without the .sh or .cmd suffix. template=linux This variable is MANDATORY. proxy_client The proxy_client directive indicates that this client acts as a TSP proxy for a remote client tunnel endpoint machine. It is set to `yes' if the machine running the gogoCLIENT requests a tunnel for another machine. (e.g.: cisco template). This directive must be used in conjunction with a static IPv4 address assigned to the client_v4 variable. NOTE: proxy_client=yes is incompatible with tunnel_mode=v6udpv4 Default: no client_v4 The IPv4 address of the client tunnel endpoint. If the host has more than one IPv4 address, it is recommended to manually set this variable with its local IPv4 address as the value. If set to auto, it chooses the source IP address used when communicating with the server. This variable may resemble the following: client_v4=auto|a.b.c.d Default: auto client_v6 This directive is similar te client_v4, except that this one is for users that have enabled IPv4 in IPv6 encapsulation (i.e., DSTM). client_v6=auto|XX:XX::XX:XX Default: auto broker_list The 'broker_list' directive specifies the name of the file where the broker list received during broker redirection will be saved. Default: tsp-broker-list.txt last_server The 'last_server' directive specifies the name of the file where the address of the last broker to which a connection was success- fully established will be saved. Default: tsp-last-server.txt always_use_same_server The value of the 'always_use_same_server' directive determines whether the client should always try to connect to the broker speci- fied by the 'last_server' directive (if any). Default: no LOGGING CONFIGURATION
log_file This directive is used to specify the quantity of information that will be logged to the file. Values range inclusively from 0 (no logging) to 3 (full logging). Default: 0 log_stderr This directive is used to specify the quantity of information that will be logged to the standard error device. Values range inclu- sively from 0 (no logging) to 3 (full logging). Default: 1 log_console This directive is used to specify the quantity of information that will be logged to the console. Values range inclusively from 0 (no logging) to 3 (full logging). Default: 0 log_syslog This directive is used to specify the quantity of information that will be logged to the syslog. Values range inclusively from 0 (no logging) to 3 (full logging). Default: 0 log_filename When logging to file is requested via the 'log_file' directive, the name and path of the file to use may be specified using the 'log_filename' directive. log_filename=[/path/to/the/]file Default: gogoc.log log_rotation When logging to file is requested via the 'log_file' directive, log file rotation may be enabled using the 'log_rotation' direc- tive. When enabled, the contents of the log file will be moved to a backup file just before it reaches the maximum log file size speci- fied via the `log_rotation_size' directive. The name of the backup file is the name of the original log file with `.<timestamp>' inserted before the file extension. If the file does not have an extension, `.<timestamp>' is appended to the name of the original log file. The timestamp specifies when the rotation occurred. After the contents of the log file have been moved to the backup file, the original file is cleared, and logging resumes at the beginning of the file. log_rotation=yes|no Default: yes log_rotation_size The `log_rotation_size' directive specifies the maximum size a log file may reach before rotation occurs (if rotation has been enabled via the `log_rotation' directive). The value is expressed in kilobytes. log_rotation_size=16|32|128|1024 Default value: 32 log_rotation_delete The `log_rotation_delete' directive specifies that the log file will be recycled on rotation. No backup log files will be kept. (if rotation has been enabled via the 'log_rotation' directive). log_rotation_delete=yes|no Default: no syslog_facility When logging to syslog is requested using the `log' directive, the facility to use may be specified using the `syslog_facility' directive. Valid values are USER, and LOCAL[0-7]. syslog_facility=FACILITY Default: USER FILES
