- netrom <subcommands>
-
- These commands influence netrom behavior.
-
- netrom acktime [<milliseconds>]
-
- (B) Displays or sets the ack delay timer, similarly to ax25 t2.
- Default is 8000ms (i.e. 8 seconds).
-
-
- netrom alias <aliascall>
-
- This sets the netrom alias call for this station. Other stations
- can connect to the ax25 callsign and to the Netrom alias (when
- set). The alias is broadcast with a Netrom broadcast. If netrom
- is not activated, you can use the 'ax25 alias' command to set the
- alias callsign, such that users can still connect to the alias,
- even though netrom activities are not allowed.
-
-
- netrom bcnodes <iface>
-
- Initiates an immediate broadcast of nodelist on <iface>. Verbose
- behavior is controlled by the 'netrom interface' command.
-
-
- netrom bcpoll <iface>
-
- Initiates a poll sent to the named interface. This poll will
- request a netrom routes broadcast from other nodes, so that the
- routing table can be updated. This is automatically done any time
- an interface is activated (or changed) for netrom. This should
- speed up route discovery at startup. This is NOT currently
- implemented in Thenet or Net/Rom nodes, but works with Data
- Engines running JNOS40 or with systems running JNOS v1.05 or
- later.
-
-
- netrom choke [<milliseconds>]
-
- (B) Display or set the time breaking a send choke. Choke is the
- term netrom uses for flow control conditions. Default is 180000
- ms (180 seconds.)
-
-
- netrom derate [ON|off]
-
- (B) Display or set automatic derating of netrom routes on link
- failure. Default is on.
-
-
- netrom hidden [on|OFF]
-
- Display or set the hidden node flag. Nodes with aliases starting
- with the '#' character are displayed using the command 'N *'.
- Default is OFF.
-
-
- netrom interface [<iface> <quality> [n]]
-
- Activate <iface> as a netrom interface. <quality> can be between
- 1 and 255. Interfaces are activated using verbose routes
- broadcasting by default, meaning that they broadcast all known
- routes. This can be changed by adding the optional 'n' parameter
- to the command. Then only the system itself will be announced in
- a broadcast, not the known routes.
-
- If the paclen of the interface is smaller then the netrom mtu +
- 20, then the netrom mtu will be set to paclen-20 . This is to
- avoid fragmentation, causing incompatibilities with none-NOS
- based Netrom nodes. See the 'ifconfig <iface> paclen' command for
- more.
-
- If <iface> has already been activated as a netrom interface, re-
- issuing the command will set <quality> and [n] to the new values.
- 'netrom interface' will show the currently active netrom
- interface.
-
- Each time an interface is activated or changed, a broadcast poll
- will be sent out on the interface. This minimizes the route
- discovery time at startup, and will update routes when the
- interface quality has changed.
-
-
- netrom interface <iface> <quality> [<min-bc-quality>] {JNOS40}
-
- Set or display the netrom interface(s) for the node. This
- command is essentially the same as the command for JNOS.
- Only nodes of min-bc-quality and better will be broadcast in a
- nodes boradcast on this interface. If <min-bc-quality> is not
- set (no value assigned), then the 'netrom minquality' value is
- used. If <min-bc-quality> = 0, then no nodes are broadcast
- except this one (same as 'n' parameter above.)
-
- Examples:
-
- netrom interface ax0 224 180 -> nodes >= 180 are broadcast
-
- netrom interface ax0 224 0 -> only ourself is broadcast
-
- netrom interface ax0 224 -> nodes >= 'minquality' are
- broadcast
-
-
- netrom irtt [<milliseconds>]
-
- (B) Display or set the initial round trip time. Default is
- 45000ms, i.e. 45 seconds.
-
-
- netrom kick <nrcb>
-
- Give the control block a kick to get activity going again.
-
-
- netrom load
-
- Retrieves the last set of netrom destination data saved with the
- 'netrom save' command.
-
-
- netrom minquality [<minqual>]
-
- (B) Display or set the minimum quality for recognizing a node
- entry. Entry's below this value are not considered valuable for
- usage. Default is 50.
-
-
- netrom mycall <call>
-
- Displays or sets the call to be used by the netrom interface.
- Note: this is a shortcut for the 'ifconfig netrom linkaddress'
- command. It defaults to the 'ax25 mycall' value.
-
-
- netrom neighbor
-
- Display all known netrom neighbors.
-
-
- netrom nodefilter <subcommands>
-
- Manipulate node filtering.
-
- netrom nodefilter add <neighbor> <iface>
-
- Add <neighbor> on port <iface> to the filter table. See the
- 'netrom nodefilter mode' command to determine the manner to
- handle node updates from <neighbor>.
-
-
- netrom nodefilter mode [none|accept|reject]
-
- Display or set the initial node filter scheme. 'none' accepts
- all netrom routes and is the default. 'accept' accepts routes
- only from nodes defined with the 'netrom nodefilter add'
- command. 'reject' does not accept routes from any nodes
- defined with 'netrom nodefilter add'
-
-
- netrom nodefilter drop <neighbor> <iface>
-
- Delete the node <neighbor> on interface <iface> from the
- filter table.
-
-
- netrom nodetimer [<seconds>]
-
- (B) Display or set the interval to transmit the nodes list. If
- you want to use other than the default, you must first attach the
- netrom interface with 'attach netrom' and then set the new
- nodetimer value. Default is 1800 seconds (half an hour).
-
-
- netrom obsoinit [#}
-
- (B) Display or set the initial obsolescense count for direct
- routes (Routes table entries) to other systems. Default is 6
-
-
- netrom obsominbc [#]
-
- (B) Display or set the minimum obsolescense count a route should
- have to be included in routes broadcasts originating from this
- system. Default is 4.
-
-
- netrom obsotimer [<seconds>]
-
- (B) Display or set the time a node obsolescence count gets
- decremented. If you want to use other than the default, you must
- first attach the netrom interface with 'attach netrom' and then
- set the new obsotimer value. Default is 1800 seconds.
-
-
- netrom promiscuous [OFF|on]
-
- (B) Enables nodes with a path quality greater than defined with
- minquality. If on, all nodes are received regardless of
- nodefilter mode. Default is off.
-
-
- netrom qlimit [<nnnn>]
-
- (B) Display or set the maximum queue limit for choke to occur.
- Similar to ax25 window. Default is 512 bytes.
-
-
- netrom reset <nrcb>
-
- Remove the control block. You can find the control block with
- the 'netrom status' or 'socket' commands.
-
-
- netrom retries [<nn>]
-
- Display or set the maximum number of retries on connect,
- disconnect or data. Default is 3.
-
-
- netrom route <subcommands>
-
- Netrom routing commands. Routes can be marked as 3 types in the
- various route displays:
-
- 'P' - a permanent route set with the 'netrom route add'
- command
- 'B' - a route received through a nodes broadcast from a
- neighbor node
- 'R' - a recorded route from an incoming packet from a not
- previously known netrom node
-
-
- netrom route add <alias> <call> <iface> <quality> <neighbor>
-
- Add a permanent netrom route. The new route is to netrom
- system <alias> with call <call>, and the route is on interface
- <iface> with quality <quality> via the neighbor <neighbor>.
-
- netrom route add salem af7s-1 port1 178 k7uyx-1
-
- A route to a direct neighbor looks like:
-
- netrom route add crv k7uyx-1 port1 192 k7uyx-1
-
-
- netrom route drop <destination> <neighbor> <iface>
-
- Delete the netrom route to call <destination> via neighbor
- <neighbor> on <iface>.
-
-
- netrom route info [<destination>]
-
- Display the route a packet would take to get to <destination>.
- If <destination> is not given, information about all known
- netrom nodes is displayed. 'netrom route info' and 'netrom
- route info *' are equivalent commands.
-
-
- netrom status
-
- Display all netrom connections.
-
-
- netrom tdisc [secs]
-
- (B) Display or set the Netrom Link "redundancy" timer. Value is
- in seconds. When no data exchange has happened during this time
- the link is reset and closed. Default is 900 seconds (15
- minutes).
-
-
- netrom timertype [exponential|LINEAR]
-
- (B) Displays or sets the type of backoff used on netrom retries.
- Default is linear.
-
-
- netrom ttl [<hops>]
-
- (B) Display or set the maximum number of hops a frame might take
- before being discarded. Default is 10.
-
-
- netrom window [<frames>]

- largest send and receive window we might negotiate. Default is
- 2.
