ipsynd IPSYND is the syndication daemon which is normally started as a local process by the main IP system. It continually checks the syndication contorl queue for new client transmissions to start (flagged by a SYN_client record in spool/syn/control). These would have been written by MUI user interface SYN or crontab or the Web interface. Once a record has been found, IPSYND opens the CLIENT parameter file for the ROUTE to start the transmission on. It then checks the PORTS file in tables/syn for a valid port to use. If this is NOT already in use by another syndication/library client, IPSYND starts program IPSYN to do the dirty work. Once started, IPSYND checks on progress. If IPSYN has failed completely or has not managed to send all the files, IPSYND restarts it. The Ports file which is in tables/syn, has the following syntax : ; comment route:(routename) host:(hostname/terminal server) port:(port no) multi:(number) telnet: where route is the name of a route file in tables/syn/route host is the hostname of the terminal server port or network device port is the port number on the terminal server multi is (optional) number of simultaneous connections on the port multi defaults to one - and for terminals servers is generally all you can have. telnet is (optional) telnet transparency OFF for this port. rawtelnet is (optional) use raw telnet (ie binary/no escapes) for this port. These parameters are case insensitive in the PORTS file as filenames etc are automatically forced Uppercase and hostnames lowercase. A single port can be specified for several routes. However only one connection will be allowed at any one time (unless 'multi' is also specified) : route:hayes12 host:svr3 port:1103 route:hayes24 host:svr3 port:1103 route:hayes96 host:svr3 port:1103 When there is more than one modem/port available for the same traffic, the 'route' is NOT unique : route:x25slow host:bigpad multi:7 route:x25slow host:lilpad This will allow up to 8 simultaneous transmissions, 7 via 'bigpad' and another via 'lilpad'. The Client parameter file has the following syntax : ; comment route: name of the Routing file in tables/syn/route alt: (optional) name of the Alternate Routing file in tables/syn/route timeout: (optional) the number of seconds delay between attempts. default is 90. tryalt: (optional) try the Alternate route every N goes. Default: 5 (or half the 'retry' parameter below) This can be tryalt:(number from 2 to 100) or tryalt:even meaning every other go remsys: name of the System file in tables/syn/remsys retry: (optional) the number of retries before stopping the the whole transmission Default: 11 Normally 11 retries is adequate - if slightly too many - but you can vary it between 1 and 100 according to taste. prior: (optional) priority of this client This is a number from 1-99 which is the order in which the client is serviced. The client with the lowest number has their files sent first. default is 50 maxtime: (optional) maximum time in secs to allow for the transmission default no limit eg. for a 10 mins timeout : maxtime:600 maxkill: (optional) script to destroy a program/ftp/script which has taken more than 'maxtime'. This is only used if maxtime has been specified and is > 0. If no 'maxkill' is specified, just the running PID is zapped. If this is 'ipsyn or 'ftp' that will be fine. However if it is a script which is running other programs, you need to kill all the 'children' too. Script '/fip/local/killer.sff' is an example. If 'ipsyn' is NOT the transmittor either a program or script or FTP can be used : script:(path and name of script) The path name is usually a good idea. Extra parameters can be added script:/fip/local/bigcommie "red" "underBed" You may also use FTP to send. The following keywords are significant : useftp: Use FTP in place of ipsyn if there are no parameters the program starts '/usr/bin/ftp -dinv' eg: useftp:/usr/ucb/ftp -zSx ftpline: A single line for the FTP command file. eg ftpline:binary General Notes on the Client file -------------------------------- -- IPSYND ignores the 'remsys' parameter as only 'ipsyn' needs that. -- These parameters are case insensitive in the CLIENTS file as filenames etc are automatically forced Uppercase and hostnames lowercase. Notes for FTP ------------- -- There are normally at least 2 lines specified is this order : ftpline:user logon,passwd ftpline:cd /remote/path where 'logon' and 'passwd' and '/remote/path' are correct for this transmission -- Other lines could be to send binary rather than ascii text : ftpline:binary or using a proxy server : ftpline:proxy open myfirewall ftpline:proxy user spy,hole ftpline:open clientbox ftpline:user anonymous,email@example.com -- Each file in the input queue at the begining of the tranmission is sent using a 'put' without you needing to specify. Please note that the filename on the remote system will be the same. So pls tidy the filename BEFORE transmission. -- A log line is automatically created in log/syn/CLIENT.date.and.time with the results of the session Notes for SCRIPT ---------------- -- the script MUST start '#! (shell)' in the first line or you will get Execlp error 8. eg: #! /bin/csh for the c shell -- Parameters for the script are : scriptname -c client -q queue -s termsvr -p port -l logfile -r inuseflagfile -z successflagfile var0 v1 var2 v3 var4 v5 var6 v7 var8 v9 var10 v11 var12 v13 var14 These variables are : 0 - program to use 2 - name of client (forced uppercase) 4 - name of queue to scan in '/fip/spool/syn' (forced lowercase) 6 - Terminal Server name - optional 8 - Port number or zero if not relevant - optional 10 - logfile. Pls write relevant information into this file as the transmission progresses. Normally the file is /fip/log/syn/CLIENT.date.and.time 12 - file to be used as a I-am-still-running flag This file is a flag for IPSYND to say the script is still running and the port is still in-use. So IPSYND creates it when the script starts but the script MUST delete it when it finishes. If you do NOT delete it at the end of transmission, the port will remain out-of-use until someone reboots the machine or use SYN to unlock the port manually. The parameter will be top and tailed with double quotes as it will contain pipes. 14 - file to be deleted if the program returns success (0) This is the control file for I-need-a-transmission. So if the script finishes with no errors (ie so it does NOT need to be restarted), it should delete/zap this control file (in /fip/spool/syn/control). This file will be top and tailed with double quotes as it will contain pipes. Note that Terminal Server/Hostname and Port Number (and there switches) are optional depending on whether they have been specified in the PORTS file. -- a ROUTE in the client file is Optional but, if stated, there MUST be a corresponding entry on the PORTS file. -- SYSTEM file (in tables/remsys) and any parameters within are ignored. -- you can add extra parameters to the script. As it can be in FipSeq, system varaibles etc can be added. Additionally any 2 letter header codes can be randomly added to the CLIENT file EG if the client file is called JUKEBOX and looks like : ; JUKEBOX ROUTE:funnycomms C1:234765403299 ALT:funnycomms A1:234765400319 L1:SECRET L2:BINGCROSBY script:/fip/local/funnies -1 \C1 -2 \C2 -y \L1 -z \L2 if there is no entry for 'funnycomms' in the PORTS file will give start /fip/local/funnies -1 234765403299 -2 234765400319 -y SECRET -z BINGCROSBY JUKEBOX jukebox spider3 0 "/fip/log/syn/JUKEBOX.10Jan97.14.10" "/fip/x/SYN|123|JUKEBOX" "/fip/syn/control/JUKEBOX" if the entry for 'funnycomms' in the PORTS file is route:funnycomms host:obnoxiousnoise port:9191 will give start /fip/local/funnies -1 234765403299 -2 234765400319 -y SECRET -z BINGCROSBY JUKEBOX jukebox obnoxiousnoise 9191 "/fip/log/syn/JUKEBOX.10Jan97.14.10" "/fip/x/SYN|123|JUKEBOX" "/fip/syn/control/JUKEBOX" The only input parameter for IPSYND is -v : print version number and exit.
