uucico(8) uucico(8) 1mNAME22m uucico - UUCP file transfer daemon 1mSYNOPSIS22m 1muucico22m [ options ] 1mDESCRIPTION22m The 4muucico24m daemon processes file transfer requests queued by 4muucp24m (1) and 4muux24m (1). It is typically started periodi cally using entries in the 4mcrontab24m table(s). When invoked with the 1m-r122m option or the 1m-s22m or 1m-S22m option, the daemon will place a call to a remote system, running in master mode. When 4muucico24m terminates, it invokes the 4muuxqt24m (8) daemon, unless the 1m-q22m option is given; 4muuxqt24m (8) executes any work orders created by 4muux24m (1) on a remote system, and any work orders created locally which have received remote files for which they were waiting. If a call fails, 4muucico24m returns 1m522m on BUSY or NO DIALTONE, 1m1022m on NO CARRIER and 1m2022m on any other error (like problems during processing of the chat script). If 4muucico24m receives any break signal (^C, ^D, ^E or ^F), it will cleanly abort any current conversation with a remote system and exit. 1mLOCKING22m 4mUucico24m locks the serial port in the same manner Getty does, but doing the equivalent of the 4mlockserial24m command before openning it. Thus, uucico's will never bump into each other on the port. Any terminal program you run should lock the serial port as well. This is done by run ning the terminal program via 4mlockserial24m with the appro priate arguments, see the manual pages for 4mgetty24m and 4mlock24m 4mserial24m for more information (nowadays, a lot of terminal programs support the 1mOwnDevUnit.library22m, if yours does, you don't need to use 4mlockserial24m). 1mCONFIGURATION22m 1mOPTIONS22m You can control 4muucico24m's runtime behaviour with several variables (specify them in AmigaUUCP's config file or the local environment). 1mCopyNotify22m 31 let's you have 4muucico24m send you mail on sev eral events. The value is bitmapped with this Bitmask: 1 notify of send failures that will not be wUUCP 0.0.28 1 uucico(8) uucico(8) retried (ie denied) 2 notify of send failures that will be retried (ie protocol errors) 4 notify of successfull outgoing file copy (uucp'd copies only) 8 notify of incoming file (uucp'd file copies only) 16 notify of incoming failure of anykind Thus, to get an email notification of any failures, use 16 or 19, for report on incoming and outgoing uucp'd files 12, set to 31 for all features. Mail is sent to 1mNotifyUser22m (see below), if unset 1mpostmaster22m. 1mNotifyUser22m uucp sets the user to be bothered with mails created due to the 1mCopyNotify22m entry (see above) to 1muucp22m. Default (if unset) is 1mpost22m 1mmaster22m. 1mUuxqtInterval22m 4 causes a start of 4muuxqt24m in the background after every 4th incoming file with a name starting with 1mX.22m*. 1mUuxqtOnlyOnce22m Y forces old behaviour, i. e. start 4muuxqt24m only exactly once, just before exiting. My be needed in some strange setups where scripts or something similar are used as 4muuxqt24m. Default is to start it at least after each role change slave>master. 1mUse7CharNames22m Y makes uucico (and related programs) use only the first 7 chars of any system's name for finding it's directory in 4muuspool:24m; 1mmust22m be set if the 4msendmail24m/4mrmail24m of wUUCP is used in conjunction with subdirectories in 4muuspool:24m. 1mUUlogs22m xferstat controls which logfiles should be main tained; currently defined are 1mxferstat22m (for the Software Brewery's xferstat file) and 1mtimelog22m (old style DUUCP timelog). If absent, 1mNO22m logs are maintained. 1mNOTE22m that the values ARE case sensitive (i. e. 1mTimeLog22m is NOT recognised). 1mRequiredSpoolSpace22m 300000 specifies the amout of space uucico should wUUCP 0.0.28 2 uucico(8) uucico(8) leave free on the local target filesystem. If unset or set to 0, the default 300000 is used. Note that this options behaviour is related to the command line option 1mTaylor22m for Taylor UUCP size negotiation: if Taylor size negotiation is used, the check for free space is performed before the transfer is initated, based on the filesize the remote tells us. If free space minus file size is less than 1mRequiredSpoolSpace22m set ting, the transfer is rejected (remote usu ally just keeps it queued for transfer on the next occasion). If that feature is not used, the check is also performed before transfer but only based on the actual free space on the tar get volume; if it's less than 1mRequired22m 1mSpoolSpace22m, the send request is denied (remote may abort the connection in this case some uucicos seem not to understand or be able to handle the SN6 code correctly =:<). But if your setting of 1mRequired22m 1mSpoolSpace22m is too low, you may still fill up your volume entirely: if you suddenly get a file of 2 MB with the default setting and only 400 BK left, the transfer will fail. The only resolution is to get the remote site to install an uucico that understands (Taylor) size negotiation, e. g. Taylor UUCP, and use that nifty feature. 1mGENERAL22m 1mOPTIONS22m Options marked with ¹ are supplied automatically on Getty initiated connections. 1mD22m dev ¹ Use device 4mdev24m; default is 1mserial.device22m (space is required) 1mU22m unit ¹ Use device's unit 4munit24m, default is 1m022m (space is optional). 1mACU22m acu Call only entries with matching 4mACU24m; this may be used to differentiate between dif ferent devices ... Let's say you have the following 1mL.sys22m entries: imart Any isdn 64000 ATD55547120 ogin: bla word: fasel imart Any isdn 64000 ATD55547121 ogin: bla word: fasel imart Any ser2 57600 ATD5550815 ogin: bla word: fasel imart Any ser 38400 ATD5554711 ogin: bla word: fasel wUUCP 0.0.28 3 uucico(8) uucico(8) If you ommit the 4mACU24m switch, 4muucico24m would dial all entries with given 4mdevice24m and 4munit24m settings; usually this would result in much nonsense, as you may use e. g. the 1misdn.device22m to call nonISDN ports, but you can't connect to the analouge modem there. Vice versa, calling an ISDN port from an analouge modem doesn't work. You can use the 4mACU24m switch to filter 1mL.sys22m entries, i. e. 1muucico22m 1msimart22m 1m722m 1mACU22m 1misdn22m 1mD22m 1misdn.device22m 1mU22m 1m022m 1mP722m would force 4muucico24m only to dial the first two entries (the ones with an ACU of 1misdn22m) and skip the remaing two. Refer to 4mL.ports.doc24m for further informa tion ... 1mx22mn Set log level for us and for remote system to 4mn24m. 1mX22mn Set log level but do not tell remote system about it. 1mxx22m Debug handshake to stdout (but not once connection is established). Useful for debugging L.Sys sendexpect stuff. 1mh022m Ignore Carrier Detect. 1mb22m Run 4mbatchnews24m before anything else. 1mq22m Don't run 4muuxqt24m. 1m722m Set 1m7WIRE22m mode for serial connections (i. e. hardware handshaking). 1mForceOurGSettings22m Instead of accepting the window and packet sizes the remote side wishes us to use, grant only the maximum of our and their settings (P5 here and P7 there would lead to P5 in direction to remote). 1mWarning:22m 1musing22m 1mthis22m 1moption22m 1mwith22m 1ma22m 1mremote22m 1muucico22m 1mnot22m 1mfully22m 1mimplementing22m 1mthe22m 1mg22m 1mproto22m 1mcol22m 1m(e.22m 1mg.22m 1mHDB)22m 1mwill22m 1minhibit22m 1many22m 1mfile22m 1mtransfer.22m 1mUse22m 1mthis22m 1moption22m 1mwith22m 1mcare!22m wUUCP 0.0.28 4 uucico(8) uucico(8) 1mproto22m n Set `protocol hack' flag to 4mn24m (0..9); not well documented anywhere (including the sources), better leave it alone ... 1mp22mprotos Set list of protocols, defaults to 4mGqg24m. 4muucico24m will choose the first common both in orginate and answer mode. 1mpri22m[1mn22m] 4muucico24m ups its priority by 1 (or, if 1mn22m was given, sets it to 1mn22m) during transfer, then downs it by 1 (relative to uucico's initial priority) to run 4muuxqt24m (i.e. initial prior ity+1 (or 1mn22m) during transer, initial prior ity1 for 4muuxqt24m). 1md022m IGNORE DTR switch forces 4muucico24m to use the +++ sequence to disconnect instead of drop ping DTR. This is a workaround for a possi ble bug in the serial device for those who experience crashes when 4muucico24m tries to disconnect. 1mn22mwindows Set protocol window size. If 4mwindows24m is not specified, a window size of 1 is forced. The default (n option not speci fied) it a window size of 7. Sometimes it is necessary to reduce the window size to 3 or 4 when connecting to heavily loaded UNIX systems. 1mt22mtimeout Set GIO protocol timeout before packet retry. Default is 5. In many cases this can cause long noactivity delays due to small glitches when, in fact, the receiving host is not loaded down. Setting the time out to 1 generally fixes this. 1mT22mtimeout Set timeout for sendexpect strings, default is 15 seconds. 1mP22msegsize Set segment size, in powers of two where a segment size of 2 == 64 bytes. The maximum segment size is 8 (4096 bytes). This option should be used only by 1mexperi22m 1menced22m 1musers22m. Larger is not necessarily bet ter since all packets are usually fixed wUUCP 0.0.28 5 uucico(8) uucico(8) length (that is, unless 1mpackets22m is used). 1mN22mhostname Sets the 4mhostname24m for this invocation; overrules the config variable 4mNodeName24m. 1mG22mg Set the grade to 4mg24m; our 4muucico24m will only transmit jobs with a grade character lower (based on ASCII order) or equal to 4mg24m; the remote 4muucico24m may or may not support this. Newsbatches usually (should) have a grade of ''e'', thus specifying ''Gd'' makes our 4muucico24m transmit only jobs with grade char acters '' '' to ''d''. The grade character is the one following the, possibly abbrevi ated, system name in command files (e. g. in ''C.hactarB0815'' is ''B'' the grade). Refer to the 4muux24m man page for further information. 1mTaylor22m Enable Taylor style size negotiation; com pare to config variable 1mRequiredSpoolSpace22m and the 4muucpinternals24m FAQ posting in news.answers. In short: on every file request the filesizes are transmitted, enabling the other side to perform some checks (e. g. `will it fit on our filesys tem?') before transfer. 1mnodelay22m Disable a .06 second delay in xgetc() which was introduced to reduce system load on machines with 030 or 040 CPUs. Since this may cause problems with other devices (e. g. an ISDN device I'm testing these days), I made this switchable. 1mpackets22m Enables packet size optimization as defined in the uucpgprotocol. 1mNOTE:22m several systems do not implement that protocol completely, thus they get confused by smaller packets as announced. (The `packets' switch makes uucico send only a 128 bytes packet if it has to send 100 bytes (too big for an 64 byte packet but fits in 128 bytes) instead of the former 1024 bytes (if P6 was used.)) Use with care! 1mGETTY22m 1mINITIATED22m 1mOPTIONS22m 1mGetty22m ¹ wUUCP 0.0.28 6 uucico(8) uucico(8) Tells 4muucico24m that it was started from a 4mgetty24m. 1mMANUAL22m 1mPOLL22m 1mOPTIONS22m 1ms22msystem Poll (callup) the specified system. 1mS22msystem Same as s but ignore time restrictions. 1mr122m Call all systems we have pending work for. 1mr122m 1ms22msystem Call this specific system if we have pend ing work. 1mq22m Do not start 4muuxqt24m when finished. 1mo22m Tells 4muucico24m to not search for a CONNECT message when carrier is detected (hardwired configuration). 1mOBSOLETE22m 1mOPTIONS/WAIT22m 1mMODE22m 1mOPTIONS,22m 1mdo22m 1mnot22m 1muse22m 1mif22m 1myou22m 1mcan22m 1mhelp22m 1mit22m 1mw22m Tells 4muucico24m to wait for one or more con nections (depending on e) AFTER having previously polled one or more systems (4mr24m, 4ms24m, 4mS24m). 1me22m Tells 4muucico24m to loop forever waiting for connections. 1mnooptions22m If 4muucico24m is run without either 4mGetty24m, 4ms24m, or 4mr24m, it will wait for a single connec tion. 1mEXAMPLE22m ; Place a line similar to this in your startupsequence! ; See GETTY manual run <nil: >nil: Getty A B19200 Mm ; Manually poll system 'foo' UUCico sfoo ; From DCRON (DCRON ENTRY) wUUCP 0.0.28 7 uucico(8) uucico(8) 40 1 * * * uucp:c/uucico r1 1mFILES22m The file names may be changed at compilation time or by the configuration file, so these are only approximations.
