SFTP Status

toms1981

Hi All,

Need some helps here. I'm trying to write a sftp script in unix env to upload my files to the server. On top of it, I need to have the logic to check whether all files are successful uploaded to the server or not. Anyone knows how to do this? Spent few days searching Internet but no luck, couldn't get the solution

“I need to have the logic to check whether all files are successful uploaded to the server or not“
well,In my opinion,all files mentioned above should be the filesystem(partition,or lv ),that means the location in which all files were created. so just check this !

SFTP does add overhead to the transfer of files. As a file is transferred between client and server, it is broken up into smaller chunks called "packets." For example, suppose each packet is 32KB. The SFTP protocol does a checksum on each 32KB packet as it is sent, and includes that checksum along with that packet. The receiver gets that packet and decrypts the data, and then verifies the checksum. The checksum itself is "stronger" than the CRC32 checksum (because SFTP uses a 128-bit or higher checksum, such as MD5 or SHA, and because this is done on each and every packet, there is a very granular integrity checking that is accomplished as part of the transfer. Thus, the protocol itself is slower (because of the additional overhead), but the successful completion of a transfer means, de facto, that it has be transferred integrally and there is no need for an additional check.
