Versions:
lftp 3.4.4
openssl 0.9.7 and 0.9.8
RedHat ES 3.0
I am using lftp to connect to a ftps server to put and get files. When
I connect to the ftps server and issue a ls command lftp hangs with the
following message: `ls' at 0 [Receiving data]. lftp does not come back
unless I issue a control-c. Interestingly enough I can use the version
of lftp that comes with RedHat ES 3.0 and the ls command works. The
RedHat version is 2.6.3.
Here is the debug session information:
lftp [EMAIL PROTECTED]:~> debug

`ls' at 0 [Receiving data]
Here is the strace output for lftp(after issuing the ls command):
