-
An application level server-client model FileSharingProtocol with support for uploading and downloading files and indexed searching.
-
Client has the ability to do the following:
-
Know the files present on the server side in the designated shared folder.
-
Download files from this shared folder.
-
File Transfer incorporates MD5checksum hash to handle file transfer errors.
##Commands
- shortlist (flag):
- Client wants to know the names of files with timestamps within a particular range
- Command format: $-> IndexGet shortlist
<startTimeStamp><endTimeStamp> - example command: $-> IndexGet shortlist YYYY MM DD HH:MM:SS YYYY MM DD HH:MM:SS
- Output: includes 'filename', 'size', 'timestamp' and 'type/permissions' of the files between the start and end time stamps *longlist (flag):
- client gets the entire listing of the shared folder/directory including 'name', 'size', 'timestamp' and 'type/permissions' of files
- example command: $-> IndexGet longlist
- Output: same as shortlist but with complete file listing
- Client can check if any of the files in the shared folder on the server side have been changed.
- verify (flag):
- Checks for the specified file name provided as a command line argument on the server side and returns the 'MD5checksum' and the 'last modified timestamp'.
- command format: $-> FileHash verify
<filename> - Output: 'MD5checksum' and 'lastModifiedTimeStamp'
- checkall (flag):
- Does the same as verify except that it does so for all files on the server side.
- command: $-> FileHash checkall
- Output: 'filename', 'MD5checksum' and 'lastModifiedTimeStamp' of all files in the shared directory
- Used to download files from the shared folder on the server side to our folder.
- flag can take value of either TCP or UDP.
- Command format: $-> FileDownload TCP/UDP
<filename> - Output: filename, filesize (in bytes), last modified timestamp and the MD5 hash of the requested file.
