I have decomissioned an old novell netware serving as fileserver for a
foxpro app with a samba virtual freebsd machine under vmware esxi
all works ok (time of response when browsing folders, throughput at
speed tests, etc), except the following foxpro related issues which I
could not solve in the last week:
- - when ran from LAN, the app randomly freezes from time to time
- - when ran from a remote location (connected via openvpn), the app takes
a very long time to open, and when searching for records it takes more
than 2-3 minutes to display the results of the query (even though other
tests have shown the connectivity is ok and file transfer is as fast as
the line allows) - this happens even if this workstation is the only one
accesing the fileserver
this behavior appeared only after switching from novell to samba
the question which would summarize this situation would be "what exactly
did the novell netware for the foxpro app which samba does/cannot do?"
I have tried with
level2 oplocks = no
oplocks = no
added IPTOS_THROUGHPUT to socket options
and the same result
testparm output is below
thank you for your time,
petre

Does the application create temporary files? Or does it try to create
temporary files? Can you configure the app to use the local client hard
drive for temporary files. I found that some MS Office Apps do funny
things with file permissions that are more likely to show up on a Samba
server (mapping NTFS to Unix permissions) than on a Windows file server
(native NTFS.)
What version of Novell Netware? Were you using IPX/SPX or TCP/IP? Where
you using the Netware client from Novell or the one from Microsoft?
Are you using a UNC path (e.g. \\myserver\share1) or drive mappings to the
network share (e.g. P: is mapped to \\myserver\share1.)

If the client machine is Win7, SMB2 support (due in Samba 3.6.0) might help as Microsoft have done lots of work on the SMB2 redirector for high latency links. Jeremy.

Windows shortcuts contain a hidden server name; if Windows has trouble resolving the server by name you can have long delays. Similarly for database queries. Moray. "To err is human.?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have found a workaround by installing a terminal server and having the app work within the lan - browsing the database is ok, only when printing to the local printer it takes about 30-40 sec however, I would like to find out what is the cause for this behaviour as shown by testparm, wins is enabled I will try to enter the machine in /etc/hosts and see if I get some improvement Moray Henderson wrote:> Petre Bandac wrote: >> - - when ran from a remote location (connected via openvpn), the app > takes >> a very long time to open, and when searching for records it takes more >> than 2-3 minutes to display the results of the query (even though other >> tests have shown the connectivity is ok and file transfer is as fast as >> the line allows) - this happens even if this workstation is the only > one >> accesing the fileserver > > Is name resolution working properly?
