(this implies slave mode)
Ifcico stands for "Internet - Fidonet Copy In / Copy Out", this is a
FidoNet(r) compatible transport agent. Currently it supports FTS-0001,
YooHoo/2U2 and EMSI handshake protocols, Xmodem (untested), Telink
(untested), Modem7 (untested), SEAlink w/overdrive and crash recovery,
Bark file and update requests, WaZOO protocols: DietIFNA, plain Zmodem
(aka ZedZip, EMSI flag "ZMO"), ZedZap and Hydra, WaZOO file and update
requests (nodelist flag should be XA). Password protected requests are
not implemented. There are plans to implement Janus protocol in the
There is also a special protocol optimized to use over TCP/IP
connection, contributed by Stanislav Voronyi <email@example.com>,
it is identified by EMSI proto code TCP (not registered).
Outbound directory structure is BinkleyTerm compatible, with domains
and point subdirectories (full 5d). There are separate "listed" and
"protected" inbound directories for the incoming sessions with the
nodes present in the nodelist(s) and with nodes that have a password
assigned respectively. Files received during an outbound session are
always put into the "protected" directory. (Only "protected" directory
is looked up by ifunpack by default).
"Magic" file request processors are executable files placed in the
"magic" directory. If request is made for a file with matching name,
the executable from the "magic" directory is run, and its stdout sent
to the requester. Full requester’s address, in the form "John Smith of
1:234/56.7" is passed to the executable in the command line. See
"misc/FILES" for an example of a magic request processor. Non-
executable files in the "magic" directory are "references". If a
request is made for a file with matching name, the file is read line by
line, and request re-made for the name found in each line. Up to 5
levels of recursion are allowed.
To run ifcico in master mode, you must make dialout devices
read/writable for ifcico, -B and do the same for the directory where
your uucp locks are created (usually /var/lock/).
To make ifcico work in answer mode, you need an FTN-able getty. Linux
"standard" getty_ps, and Gert Doering’s mgetty (from the mgetty+sendfax
package) and later versions have fidonet support built-in. Getty must
distinguish incoming FidoNet type calls, and start ifcico with one
FTS-0001 call: "ifcico tsync"
FTS-0006 call: "ifcico yoohoo"
EMSI call: "ifcico **EMSI_....."
(in the latter case the received EMSI packet should be passed without
If you are using getty_ps, don’t forget to create the file
/etc/default/uugetty with the contents similar to the following (case
When called without parameters, ifcico runs in slave mode and
determines the type of inbound session itself. This mode may be used
when ifcico runs as an internet or ISDN daemon.
To make ifcico scan for pending outbound mail and do appropriate calls,
start it with "-r1" flag. To force polling of particular nodes,
specify these nodes in the command line (addresses should be in domain
notation, e.g. "ifcico f23.n5020 f155.n5020"). The latter implies
master mode (-r1). Note that "hold" packets and files, as well as file
requests, do not cause the node to be polled.
Inbound directory is created automatically if it does not exist, along
with the "tmp" subdir. The latter is used while receiving files. After
being successfully received, the files are moved up to the "inbound"
directory. "protinbound" and "listinbound" directories accept files
received during password protected sessions and session with the nodes
present in the nodelist(s) respectively.
Ifcico can use text format nodelists in original (MS/DOS) form with
<CR><LF>’s as well as in UNIX form, with <LF>’s only. When you get a
fresh nodelist, or change the "nodelist" statements in the config file,
you must rebuild index with ifindex program.
For outgoing calls, status files are created for nodes, with the
extention ".sts". These are ascii files containg three decimal numbers
in a single line:
time retries code
time is the last call attempt time (attempts failing with "retry time
not reached" do not count). It is unsigned long representing the
number of seconds since the epoch.
retries is the number of consequitve call attempts made that returned
"call failed" or "could not establish session". This field is zeroed
when call succeeds.
code is the return code of the last attempt.
nlpatch program compiles a new version of the nodelist from the old
nodelist and nodediff.
-h Display a short help message.
-x Verbosity Set the debug verbosity Verbosity may be a
number from 0 to 32 to set ’on’ bits from 1 to number, or a string of
letters where ’a’ = bit 1, ’b’ = bit 2, etc. up to bit 26.
-I File Use the alternate configuration file File.
-r Role 1 - master, 0 - slave. default is 0 (slave mode)
if no node is provided; else the default is 1 (master mode).
-a Inetaddr Tell an internet address Inetaddr to make a
connection by TCP/IP. A specific port can be given ( -a Inetaddr:Port
). The default is the one given by fido in /etc/services.
-t Mode 0 - TCP, 1 - Telnet-Vmodem. Tells the mode to use
for TCP/IP connections, the default is TCP mode (-t0)
For modem conections, this overrides the phone number given in
For modem connections, this overrides the tty value give in the
Node This is the FTN addres of the node to call. The
addres must be in the format "[pNN.]fNN.nNN[.zNN[.domain]]".
tsync | yoohoo | **EMSI_INQC816 Those values are
typically given by an FTN-able getty ( mgetty or getty_ps ), they
determine the type of FTN protocol to use. They imply slave mode.
ifcico returns maximum return code for all calls made. Codes are as
0 Successfull call
1 Dialout port unavailable
2 Dial failed (no "CONNECT" or TCP connection failed)
3 Could not reset the modem (no "OK")
4 System locked
5 Retry time not reached
6 Fatal error in nodelist lookup
7 Call prohibited by config options
8 Phone number unavailable
9 No matching ports defined
>10 Session failures (not defined yet)
30 Could not establish session
