Segmentation fault in 3.0.3

[Wang WenRui]

Hi,

  There is segmentation fault when I connect to a ftp site. Again, this
  is inconformity of the server software with RFCs. But lftp shouldn't
  crash.

  The debug message and stack trace is :

Detaching after fork from child process 14188.

sorry, it seems to be inconformity of the server software with rfc 2389.

Cannot connect to remote server in 3.0.3

[Wang WenRui]

Hi,

  lftp cannot connect to a remote server, which works well with other
  clients. I believe it is a bug in ftpclass.cc dealing with 221 code.

  lftp [EMAIL PROTECTED]:~> debug
  lftp [EMAIL PROTECTED]:~> ls
   Connecting to mail.ustc.edu.cn (202.38.64.10) port 21

  Thanks.
