The check- sums are from the standard unix sum(1) program. On Berkeley systems, just say 'sum filename', on AT&T sytems, use 'sum -r filename' to get matching results. uuencoded files length sum (1) =============== ======= ======= Juggler 19018 44739 Juggler.info 807 36567 movie.1of7 58053 37844 movie.2of7 58094 43005 movie.3of7 58094 15044 movie.4of7 58094 06921 movie.5of7 58094 07846 movie.6of7 58094 35257 movie.7of7 58792 45375 movie.data 407315 52054 after uudecode length sum (1) =============== ======= ======= Juggler 13784 43398 Juggler.info 562 29448 movie.data 295610 44390 Now if your lengths of sums differ in just a spot or two, you can ask some other site to mail you the correct version. If everything is screwed up, probably some gateway digested your newsfeed and you need to get a copy on diskette or from some other network. Some common uudecode problems: 1) Your mailer eats blanks at the ends of lines. Uudecode expects lines where the length is specified by the first character. You can use the 'l' or ':l' command in ed or vi respectivly to check for this. If this is your only problem, write a little program to pad out the lines. 2) Some funny characters substitutions occured with braces, brackets, squiggles and the like. Some news feeds include ibm systems, especially for bitnet sites. Since IBM systems don't use the ascii character set, there is often some transliteration involved. Too bad... 3) The files were truncated somewhere along the line. The files begin with begin and end with end. All of the lines except the last begin with an M. If this isn't the case, either you lost something, or neglected to edit out the headings or .signature info in some of the files. Well, enuf. Andy already mentioned that this demo requires all of the memory on your system. You need a stripped down startup file that doesn't allocate any buffers or other goodies. Xmodem users should check that they didn't end up with a bunch of control/Z's at the end of each file. To the person who posted the checksum program: your heart is in the right place, but your code isn't very portable. It will give different results for the same data on different systems. This is why I stuck with the unix sum utility... Oh yeah, one last thing... You might want to change the filemode in the first line of a couple of the uuencoded files. My system decided that they should be owned by uucp and not readable by *ME*. 8-( -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
