Tools ===== repo tools use the command line to instruct different behavior of repo. ## ndnputfile This tool is used to insert data into repo. $ndnputfile <command> repo-prefix ndn-name filename Here is a list of commands supported so far: $ndnputfile -h -u: unversioned: do not add a version component -s: single: do not add version or segment component, implies -u -D: use DigestSha256 signing method instead of SignatureSha256WithRsa -i: specify identity used for signing Data -I: specify identity used for signing commands -x: FreshnessPeriod in milliseconds -l: InterestLifetime in milliseconds for each command -w: timeout in milliseconds for whole process (default unlimited) -v: be verbose Next, we will introduce these commands one-by-one: #### List If you want to add a version number manually after the ndn-name, you can specify -u. Otherwise, ndnputfile will automatically append a version number according to current time. For example $ndnputfile -u /exmaple/repo/1 /example/data/1/%FD%00%00%01G%F0%C8%AD- test.txt $ndnputfile /exmaple/repo/1 /example/data/1/ test.txt In both cases, the real nun-name is /example/data/1/%FD%00%00%01G%F0%C8%AD-. If you want to use exact one data to storage your file, you can specify -s. Otherwise, your file content will be separated into multiple segmented data $ndnputfile -s /exmaple/repo/1 /example/data/1/ test.txt In this way, all you content will be stored in one data packet and no segment number will be appended. The real ndn-name for example will be /example/data/1/%FD%00%00%01G%F0%C8%AD-. If the file is large enough and cannot be stored into one data packet, you should not specify -s. In this way, ndnputfile will automatically separate the data content and use the segment number to identify different segments. $ndnputfile /exmaple/repo/1 /example/data/1/ test.jpg In this case, data will be segmented and the segment number starts from 0. The real ndn-name could be /example/data/1/%FD%00%00%01G%F0%C8%AD-/%00%00. Notice: If the data is not large enough to use segmented data to insert, not specify -s will only generate one segment, whose real ndn-name contain a segment number /%00%00. You can specify -D to choose the DigestSha256 as the signing method to sign data packet and command interest $ndnputfile -D /exmaple/repo/1 /example/data/1/ test.txt You can also specify the identity to sign command interest or data by using -I and -i respectively. $ndnputfile -I /ndn/test/alice /exmaple/repo/1 /example/data/1 /example/data/1/ test.txt $ndnputfile -i /ndn/test/bob /exmaple/repo/1 /example/data/1 /example/data/1/ test.txt You can set the data freshness time by using -x. The time is measured in milliseconds. For example: $ndnputfile -x 4000 /ndn/test/alice /exmaple/repo/1 /example/data/1 test.txt If you want to specify the interest life time, you can use -l to set the interest time out value. For example. $ndnputfile -l 1000 /ndn/test/alice /exmaple/repo/1 /example/data/1 test.txt You can use -w to set the timeout for the whole insert process. The process will stop if time expire. You can print the log information by specifying -v.
