Description shan 2005-12-08 15:12:04 UTC
Description of problem:
FTP to NFS Client ( RHEL 2.1 -- ia64 --WU-ftpd ) hangs if NFS server is down.
Telnet happens Fine in this situation , also here there is no need for the 
exported file system available   for FTP to function fine.

In case of  Vsftpd (RHEL -4)  ftp to the NFS client ( RHEL 4 --VSFTPD)functions 
fine  even when the NFS server is down.



Version-Release number of selected component (if applicable):	wu-ftpd-2.6.1-20


How reproducible:

Case 1. 
Mounted the /tmp folder of the NFS server (RHEL 4) to a NFS Client (RHEL 2.1). 
Shutdown the NFS server (RHEL 4) , FTP to NFS Client( RHEL 2.1) failed , with 
Session time Out message. 
Note :-In the tested Lab system , RHEL 2.1 is with the latest versions of nfs-
utils , portmap , wu-ftpd for RHEL 2.1. 
Case 2. 
Mounted the /tmp folder of the NFS server (RHEL 2.1) to a NFS Client (RHEL 4). 
Shutdown the NFS server (RHEL 2.1) , FTP to NFS Client( RHEL 4) is happening 
fine . 


  
Actual results:When the NFS server is down FTP to WU-FTPD will fail where as 
FTP  to VSFTPD will work fine.


Expected results:FTP to WU-ftpd should work similar to VSftpd , even when the 
NFS server is down as there is no relation between the exported file system 
(/tmp) and the ftp login.


Additional info: RHEL 2.1 (wu-ftpd) packages is installed and tested with the 
latest updates version available in the rhn.redhat.com 

Hence a wu-ftpd version or any other FTP package is needed for RHEL 2.1 in 
which the ftp wonât get affected due to the NFS server in-availability.
