Anomalies fixed in NFS 203 Patch
****************************************************************************
Nested subdirectories of any length can be accessed now from NFS name space in
an FTP session.
For a user whose password has expired, and only grace logins are left, FTP-
Server would simply give the message "Incorrect password" and deny login for
the user, thereby wasting a precious Grace login for the user.NFS203 patch
fixes this by allowing the ftp client to login with a clear indication that it
is a grace login, and that he needs to change his password from a NetWare
client.
FTP user with a mixed-case home-directory would not be able to login as he
would not be able to CD into the home-directory, this bug has been fixed.
Range of ports that a passive mode FTP-server should use can now be specified
from NWPARAMS file under the FTPSERV section. This feature can be turned off
if not required. However, this feature is currently *not* configurable from
UNICON. This feature was added to support double firewalls, where both the
FTP-server and the FTP-client are protected by their respective firewalls; and
the firewall can be instructed to allow a range of ports to be accessed from
outside.
Fix for supporting FTP clients whose home directory has mixed cases and the default name space
is nfs.
A new configurable NWPARAMS parameter called "HOME_DIR_CASE" is introduced. This parameter
can have the following permissible values:
UPPER
LOWER
STRICT
Eg.
[FTP_SERVER]
HOME_DIR_CASE UPPER
2. STRICT is assumed by default when this parameter is not found in the NWPARAMS.
This will preserve the existing behavior of the FTPSERV.
3. This parameter is used only at the time of logging into the server with NFS
name-space as default name-space. It does not have any effect on the case sensitivity
of NFS name-space for other operations such as DIR, CD, etc. It does not affect
operations in DOS name space.
4. Using this parameter: Setting this parameter to UPPER will make use of the user's default
home-directory in UPPER-CASE before CD'ing into it at the time of logging in to the FTPSERV.
Eg. If users's default home-directory is "Admin", then FTP will try to login to a directory
"ADMIN" when this parameter is set to UPPER. If a directory "ADMIN" exists (all in UPPER
CASE), only then the user will be able to login successfully.
Similarly, setting it to LOWER make use of the user's default home-directory in lower case
before CD'ing to it at the time of logging in to the FTPSERV.Eg. If users's default home-directory
is "Admin", then FTP will try to login to a directory "admin" when this parameter is set to LOWER.
If a directory "admin" exists (all in lower case), only then the user will be able to login successfully.
Setting it to STRICT will not do any conversion, and will try to CD into the user's default
home-directory as it is.Eg. If users's default home-directory is "Admin", then FTP will try
to login to a directory "Admin" when this parameter is set to STRICT. If a directory "Amin"
exists (all in Proper Case), only then the user will be able to login successfully.
5. Warning: If there are two directories differing only in case (this is possible in NFS
name-space), and if one of them is the default home-directory of a user, then with this case
conversion, it could so happen that the user will get into the other directory. Eg. "Admin"
is the default home-directory. Let there be another directory called "ADMIN" too. If you set
the parameter to "UPPER", then the user gets logged into "ADMIN", not "Admin" as expected.
So the side-effect of adding this feature is that you are forced to have case-insensitive
unique named home-directories for each of the users.
NFSGW Synchronization issues has been addressed.
LPR print Gateway Stack Over Flow abend has been fixed.
Automatic Initialization of NIS Maps: A new command line option for UNICON has
been introduced "Load Unicon /n NIS".
This command line option will achieve the following under Unicon Menu
Manage Services -> NIS - > Initialize Master NIS Maps
A new parameter has been introduced in NWPARAMS that would allow LPRGWY to load
even if NETDB has not logged in. SKIP_NETDB_MAPPING Default is OFF, If set to
ON LPRGWY would load without NETDB logging in.
****************************************************************************
Anomalies fixed Prior to NFS 203 Patch
****************************************************************************
When the NetWare server ran the NFS NLMs, the PACKET RECEIVE BUFFERS
continued to increment up to the value set as MAXIMUM PACKET RECEIVE
BUFFERS.
The server appeared to hang, and MONITOR showed high CPU utilization with
most, if not all, ECBs belonging to TCP/IP process.
When reading files, the NetWare NFS server would occasionally abend due to a
page fault.
When accessing files on a NetWare NFS server, file ownership and access
permissions randomly changed.
During install, after all of the files were copied to the server and UNICON was
loading,the installer tried to log in and received the error message that
"Remote TCP/IP administration not running."
The NetWare FTP server would not allow users to log in after the administrator
had modified FTP access through the FTP Administration option in UNICON.
The NetWare FTP server returned a generic return code of 200 upon successful
completion of a directory change. Some clients expected a specific return code
of 250.
The NetWare FTP server did not allow multiple anonymous users to access the
same file at the same time.
When users were at the root level of a volume on a NetWare FTP server, they
could not change to a subdirectory without using an absolute path name.
When a user logged in as an anonymous user, the NetWare FTP server required
a password (when a password had not been assigned).
The NetWare FTP server did not support the STORE UNIQUE (STOU; SUNIQUE)
command.
The NetWare FTP server user could not log in if the NDS home directory was on
a remote server that was down.
The NetWare DNS server did not properly handle a primary domain name suffix
with anything other than .COM.
UNICON failed to save the DNS database to text files. The following error
message was displayed: "NIS and DNS services not configured to run on this
machine."
The NetWare DNS server did not properly resolve the MX (mail exchange) query.
The NetWare DNS Server abended while doing a zone dump from a secondary
server when the size of the reply was larger than the buffer allocated by the
DNS server.
SUN's NIS+ server, when running in YP emulation (NIS emulation) mode, did not
support YPPROC_ORDER remote procedure call. This resulted in a situation where
YPXFR.NLM could not get the NIS maps order numbers and would abort the
transfer of maps.
The NetWare NFS gateway failed to mount DEC VMS file systems.
The NetWare NFS gateway did not support the SGID bit on remote directories.
The NetWare NFS gateway server abended when it tried to mount more than 64
volumes.
The OS/2 session hung while copying a file to a NFS Gateway volume.
Even though the NetWare user was mapped, the NFS Gateway displayed the message:
"Login user xxx does not have NFS UID and GID."
From the UNICON menu, if the administrator selected the following options
(Manage Services-> NFS Gateway->Configure Volumes) and then pressed the <F4>
key, incorrect resource information was displayed.
When the UNIX server had a hard disk larger than two Gigabytes, incorrect
volume information was displayed and write-through was unnecessarily turned on.
A NetWare client could not see changes made from UNIX to a NetWare NFS gateway
directory until a file scan (DIR or other NetWare command that performs a scan)
was done.
When NetWare NFS print services was loaded while NDS was unloaded, the NetWare
server abended with the following message: "NLM unloaded without deleting all
its semaphore."
The PLPD module would unload if the NETDB module did not successfully log in
to NDS.
The PLPD module used too much server memory when several jobs were sent from
UNIX hosts.
After applying the FORTRAN filter, FORTRAN print jobs would not print.
When UNIX to NetWare printing was configured with UNICON, the NetWare server
would occasionally abend.
LPR clients were unable to submit print jobs to NetWare queues when the queue
names were longer than eight characters.
LPR gateway jobs were printed twice if the printer ran out of paper. When more
paper was added, the printer finished the interrupted print job and then
printed the job again.
The PLPD module refused LPR requests from unauthorized port numbers (port
numbers less than 1024).
When using the LPR gateway, PSERVER showed "PRINTER MAY NEED ATTENTION" status
and had to be restarted.
When using the LPR Gateway, PSERVER showed the XRP printer state changing
between "Ready for New Job" and "Error at remote Unix host." The PKERNEL module
displayed the following error message: "No sequence numbers available for the
remote host."
When the LPR Gateway was unloaded and then loaded again, the LPR Gateway
displayed the error message: "No configured UNIX printers."
When running SAA on a server with Netware NFS, TN3270 sessions through SAA
did not work. The solution for this problem is to ensure that SAA is loaded
before UNISTART.NCF in the AUTOEXEC.NCF file.
When doing a login to a UNICON session on the SFT-III server, an error is
displayed "REMOTE TCP/IP ADMINISTRATION NOT RUNNING". If you get this error,
it is necessary to edit the MSAUTO.NCF and include the following command:
LOAD MSIPC.NLM
If you have installed the online documentation and would like to access the
online documentation over the network from a Windows 95 workstation, you need
to map a network drive to the sys: volume on the server where the online
documentation is installed. You can view the online documentation by executing
the documentation viewer only through a mapped network drive.
