- LOGCHECK -- Checks log files for strings Alton Moore
- which signify good or failed Fidonet 1:397/5264 (NEC)
- net connections in batch. WWIVnet 1@1042
-
- Version 1.0, 08/16/1992
-
- ---------------------------------------------------------------------------
-
-
- INTRODUCTION:
- -------------
- This program is intended to determine whether a network transfer occurred
- (say at least once per night) by scanning a network log file for a
- specified string. The addition to the log of text containing this string
- causes the program to exit with a certain error level, which you may use
- in your batch files to determine whether the network transfer just
- attempted was successful.
-
- Although this program is not network-specific in any way, I will
- generally give examples for a FrontDoor/WWIV setup.
-
-
- THEORY OF OPERATION:
- --------------------
- The program will perform 2 functions: marking the current size of a given
- log file and checking that file for the addition of text containing a
- target string (say "connected"). These functions are meant to be used
- before and after a network transfer attempt to determine whether the
- attempt was successful. These functions, in conjunction with a flag
- file, can be used to ensure that, for example, your system calls another
- system at least once per night. The first step would be to create a flag
- file (probably in batch) as soon as you want your system to start trying
- to call the target system. You would create an event which created your
- flag file:
-
- .
- .
- echo This file's presence causes my FrontDoor batch file to do a WWIV callout!
- >\bbs-util\wwiv1040.flg <--- continuation of previous line
- .
- .
-
-
- Then, at some point in your batch file which is often traveled by your system,
- for example just after every net connection or human caller, you might put:
-
- .
- .
- if exist \bbs-util\wwiv1040.flg goto wwiv_callout
- .
- .
-
-
- And then, the actual callout code:
-
- :wwiv_callout
- cd \wwiv
- \wwiv\utility\logcheck -m \wwiv\gfiles\netdat0.log
- \wwiv\utility\clout.exe 1040 1
- \wwiv\utility\logcheck -p 5
- \wwiv\utility\logcheck -s connected
- if errorlevel 1 goto run_frontdoor
- del \bbs-util\wwiv1040.flg
- goto run_frontdoor
-
-
- Note that above, in the first invocation of the program, -m is used as
- the first argument to indicate storing the name of the file we're
- referring to (supplied as the second argument) as the first line of the
- holding file logcheck.dat and the current size as the second line.
-
- The -p invocation prints out the addition to the log file to the screen,
- pausing for 5 seconds to let you get a gander at the results!
-
- The next invocation (scan, indicated by -s) scans the file stored as
- the first line of logcheck.dat, starting at the byte indicated by the
- second line of logcheck.dat. The second argument is the string to scan
- for (use quotes to encapsulate strings with odd characters or spaces).
- If the string is found, then error code 0 is returned; if not, then 1 is.
-

-
- SYNTAX:
- -------
- Run the program with no arguments for the latest help information.
-
- The functions supported by the program are:
- -m [logfilespec] remembers the filespec of the log file
- and the current size and stores them.
- -s [stringtoscanfor] returns 0 if this string was found to be added to
- the file since the last mark operation.
- -p [delaytime] prints the new part of the log to the screen,
- pausing for [delaytime] afterwards.
-
-
- The error codes returned by the program are:
- -m function: 0 = successful
- 2 = bad parameter (function or filename)
- -s function: 0 = successful (string found in new part of log file),
- 1 = unsuccessful (log file same size or smaller or string
- not found in new part of log file)
- 2 = bad parameter (function or filename)
- -p function: Oh, just look at the source....
