The SFTP server is able to accept >2GB files as I can successfully upload from an Ubuntu version of lftp. Here are logs from lftp on Ubuntu "put 3gb_file" to the exact same SFTP server: ---- path on wire is `/3gb_file' ---> sending a packet, length=26, type=3(OPEN), id=1346 <--- got a packet, length=10, type=102(HANDLE), id=1346 ---- got file handle 36 (1) ---> sending a packet, length=32790, type=6(WRITE), id=1347 ---> sending a packet, length=32790, type=6(WRITE), id=1348 ---> sending a packet, length=32790, type=6(WRITE), id=1349 ---> sending a packet, length=32790, type=6(WRITE), id=1350 ---> sending a packet, length=32790, type=6(WRITE), id=1351 ---> sending a packet, length=32790, type=6(WRITE), id=1352 ---> sending a packet, length=32790, type=6(WRITE), id=1353 ---> sending a packet, length=32790, type=6(WRITE), id=1354 ---> sending a packet, length=32790, type=6(WRITE), id=1355 ---> sending a packet, length=32790, type=6(WRITE), id=1356 <--- got a packet, length=49, type=101(STATUS), id=1347 ---- status code=0(OK), message=The write completed successfully ---> sending a packet, length=32790, type=6(WRITE), id=1357 ---> sending a packet, length=32790, type=6(WRITE), id=1358 <--- got a packet, length=49, type=101(STATUS), id=1348 ---- status code=0(OK), message=The write completed successfully <--- got a packet, length=49, type=101(STATUS), id=1349 ...

Can I assume lftp running on AIX was compiled without largefile support? Jimmy -----Original Message----- From: Alexander V.

I think it is a bug on the server, but it can also be caused by incorrectly formed requests. You can try to download a large file from annother sftp server to find the actual reason for this misbehavior. -- Alexander. _______________________________________________ lftp mailing list lftp@uniyar.ac.ru http://univ.uniyar.ac.ru/mailman/listinfo/lftp
