RE: problem with DataConnection.transferToClient(outputStr);

[Janardhanan, Ajith (AJANARDH)]

I am using the ftp command in windows and solaris as the client. The log
file is attached for the ls -l command from the ftp terminal. While
debugging, the found that the command sent is NLST -l, which in turn
lists the directory in the NLIST_FORMAT correctly, but the '-l'
parameter is somehow translated as the remote directory parameter.
I built the apache ftp server code taken from the 1.4 branch in Nov
2007. The result is the same even without my tweaked code. ie; with the
plain apache ftpserver code, an ls -l gives the same result.


Thanks
Ajith

What client are you using for testing? Can you repeat this behavior with
any client? Could you provide the deb level log from the server?
