Q1: What versions of Windows are supported?
A1: We support all currently supported Microsoft Windows versions. Having said that, Allegro NFS should work on all versions going back to Windows Vista. We even have a build which works on Windows XP. As of v7.0.0 the product is 64bit. If you need a 32bit version please contact us. Contact [email protected] for more information.
Q2: How do I go from the evaluation to the paid version, or upgrade from one version to another?
A2: We recommend these steps to go from the evaluation to paid version, or to upgrade from one version to the next:
- Copy the
nfs.cfgfile from the existing installation directory, which defaults to
c:\AllegroNFS64(64-bit), to somewhere safe.
- Uninstall the current version, saying “yes” to the question about preserving the
nfs.cfgfile. Answering “yes” will cause all files in the installation directory to be removed, except this file.
- Install the new version. This might require you to reboot.
Q3: Why do I get no response from the NFS server?
A3: If you are using firewalls on Windows or any of the clients, their configuration must be adjusted to allow various ports through to the server and clients.
NFS works by using several subprocesses to handle various aspects of NFS operation. These subprocesses are called
lockd. Each of these subprocesses uses one TCP port and one UDP port to listen for requests.
nfsdhave standard port numbers that they use.
portmapperuses port 111 and
nfsduses port 2049.
lockdhowever, use arbitrary port numbers that the
portmapperassigns. This number will likely be different every time Allegro NFS initializes and can be a problem if you want to do a one-time configuration of your firewall to allow NFS to work. To help with this problem, Allegro NFS allows you to assign these services a consistent port number. You can specify the port number by starting the Allegro NFS configuration program, clicking on the “Global” tab, and supplying the port number of your choice in the “Subprogram port assignments” area. Keep in mind that if you use a port number that is being used by some other program, Allegro NFS will fail to initialize correctly and NFS operations will not work. If this happens, try a different port number and restart Allegro NFS.
Here are the ports which must have access through your firewall:
- UDP and TCP port 111 (for portmapper protocol)
- UDP and TCP port 2049 (for NFS protocol)
- Your chosen UDP and TCP port for
Specification of these ports requires Allegro NFS Server version 4.3 or later.
Q4: Are symbolic links supported?
A4: Yes, but it requires Allegro NFS Server version 5.0 or later.
chmod on the client supported?
chmodis not supported.
chmodrequests are simply ignored by Allegro NFS. This was a specific design decision to avoid confusing problems that can be caused when the
chmod‘d files are subsequently accessed on the Windows side. The execute bit is simulated based on filename extension. Files with filename extension
comautomatically have the ‘x’ bit set. If you need the execute bit set, you can make Allegro NFS enable the execute bit on every file, which may suit your needs. You can do this by editing the “set mode bits” setting for the export using the configuration utility. If you use a value of
111, that will set the execute bit for all files.
Q6: When starting Allegro NFS I get ‘Error: portmap_set failed’. What’s wrong?
A6: This error indicates that you likely have another vendor’s NFS product installed and it is causing a conflict when Allegro NFS attempts to set up a portmapper at the same port. The solution is verify that other NFS server products are completely uninstalled, reboot, and attempt to start Allegro NFS again. In particular, customers have noted that Microsoft Services for UNIX includes a portmapper daemon. Uninstalling or disabling this process has been known to resolve this issue.
Q7: I exported a mapped network drive or a UNC path, but when I access the export from an NFS client, the files are inaccessible. Why doesn’t this work?
A7: The Allegro NFS service normally runs under the Windows
LocalSystem) account. This account is very powerful and has access to all files on the local computer (although Allegro NFS will restrict access according to the configuration you supplied). However, the
SYSTEMaccount does not have access to network drives.
To remedy this problem, you can reconfigure the Allegro NFS service so that it runs under a normal user account. To do this, right-click on My Computer and select ‘Manage’. Go into “Services and Applications”, then “Services”. Locate the “NFS Server” entry, right-click on it and select “Properties”. Select the “Log On” tab. You’ll find that it is currently set to “Local System account”. Select the “This account” radio button and fill in the account name (and associated password) for the account that you want Allegro NFS to run under. Then go back to the “General” tab and stop and restart the service.
Note that the user account that you choose will only be able to successfully export files/directories that it normally has access to.
Q8: Why don’t the clients see the exports I created?
A8: Make sure your exports start with a slash (/). The usual way NFS clients reference mounts is from the root (
Q9: The NFS service will not start and I see “wait-for-service-to-start: Unexpected service state: 3” in the NFS console. How to fix?
A9: Likely you have another NFS server installed which is holding onto ports Allegro NFS needs to start. Uninstall or stop the other service, and Allegro NFS should start properly.
Q10: I played around with other NFS server products, but now I’m trying yours, so why are my NFS client requests hanging?
A10: It is likely you have another NFS product installed. Make sure all other products are uninstalled.
Q11: Why can’t I mount my export on Linux clients with
nfs-utils version 1.2.2 or greater?
A11: Newer versions of mount use
mount.nfs4by default. You’ll need to specify version 2 or 3 in your
mountcommand. Usually this is done by specifying
-o vers=3on the command line, but please see
man mount.nfson your system for more information on how to specify the version.
Q12: Why do I get the following error message in Windows:
Error 1061:The service cannot accept control messages at this time. when I try to restart the Allegro NFS service?
A12: You’ll need to restart the service as the Administrator user.
Q13: How do I present the same share with different permissions?
A13: The internal model of Allegro NFS does not allow this, but there is a workaround: use the Windows
SUBSTcommand to make additional drive letters that refer to the same real drive where the share resides, and then have Allegro NFS use different drive letters for the same shared directory. Say you want to share
C:\TMPto several different hosts with different permissions (e.g., different UIDs). You couldsubst d: c:\ subst e: c:\
then make shares for
E:\TMPthat offer these different qualities.
Q14: How do I fix the error “Attempt to take the car of which is not listp” found in the console/log file?
A14: This problem has been fixed in recent versions of AllegroNFS, but if you are running an older version
you might see this error, which prevents the NFS service from starting up. To fix it, remove the file
installation directory and start the service manually.
Q15: Does Allegro NFS use Log4j?
A15: No. Franz Inc. does not use Log4j in any of its commercial products. Please see our Press Release on this topic.
