NFS4 and dual symbolic link fails

Very elegant autohome/NIS scripting system to jumpstart and link up homes and user/privs/pkgs etc exists. Upgrade to Solaris 10.
As long as I force users to use NFS3, they can autohome and get all the items they need, no problem. The moment NFS4 is used, and two symbolic links are traversed--the NFS mount fails.
E.g. the autohome is mounting:
/globalhome/tools/$solaris_ver/$CPU/
which is really /globalhome/tools/solaris8/sparc9
If the mount is only /globalhome/tools/$solaris_ver and they use NFS4 = success. The moment two symbolic links AND NFS4 are used together for the NFS mount ( autohome ) everything falls apart.
Thoughts?

NFS4 does not use mountd to effectuate the mount and is
therefore unable to resolve symbolic links.
I wonder if this was an oversight or were links deemed
insecure and incompatible with the new ACL mechanisms.
P.A.

Symbolic links on samba network drives broken?

Note: I first posted this in Apple.com > Support > Discussions > Mac OS X v10.5 Leopard > Using Mac OS X Leopard where it was suggested I post here. In my readings it looks like 10.6 may solve some of this but I'm not sure.
I'm seeing the following sort of behaviour on all of the macs I have tested in the following configuration:
Network file server:
Solaris 10
samba 3.4.2
Macs:
Leopard 10.5.6
Connect to exported folders via smb in finder "connect to server". In the examples below abc123 is a remote folder.
Open terminal and try the following tests:
1. Attempting to remove a symbolic link fails.
* cd /Volumes/abc123/tmp
* touch foo
* ln -s foo .bar # this works
* rm .bar # fails with no message
* rm foo # succeeds
* rm .bar # fails with no message
If the symbolic link is to a socket then you at least get a message when rm fails ("rm: .parentlock: No such file or directory" as an example for a link created on the remote drive by Thunderbird or Firefox).
2. Removing linked file removes unlinked file??
* touch foo
* ln -s foo bart
* touch ._bart
* ls -la # observe that ._bart exists
* rm bart
* ls -la # observe that bart still exists, but that ._bart is gone!!!
3. Removing linked file does not work.
* ln -s bart ._bart
* rm bart # fails
4. Hard links do not delete either.
* touch foo
* ln foo ._bart
* rm foo
* ln -s bar ._bart # ln: ._bart: File exists
* rm ._bart # rm: ._bart: No such file or directory
5. Symbolic links are copied instead of the file contents.
* touch foo
* ln -s foo ._blaht
* cp ._blaht /tmp
and observe that, in /tmp, you have "._blaht -> foo" instead of the actual file.
So can anyone else reproduce any of the above problems? In my limited searching for samba related problems I did not see any posting about this type of situation. Also, everything works just fine on local drives.

Depending on the filesystem, Mac OS X creates ._foo files when you create a foo file, so you'll probably have to live with that. For example, for each file on my FAT32-formatted USB flash drive there is a ._xxx file. Others may be able to explain what these things are. I'm pretty sure they contain file metadata, perhaps like .DS_Store files created for other file systems.

SMB Symbolic Links disabled after update to 10.6.4

I just found out how to fix Access Denied messages for any WIndows share that includes a symbolic link directory. Due to a security issue the default was changed to:
\[global\]
wide links = no
This disables access to symbolic links.
See http://www.samba.org/samba/news/symlink_attack.html
I changed it back to yes for now to get it working. Will look into this more when the network is not in use. This should have been noted in the smb.conf file.

For the non-geeks in the audience. 10.6.4 broke access to smb folders being shared by a 10.6.4 machine. My popcorn hour media stremer would no longer use symbolic links as a means to find all my movies spread out on 2 disks. It could see the links as files and clicking on them gave an error message. In my case these links a symbolic links of the folders on my 2 movie drives, labeled sci-fi, westerns, etc. All the links are in my Movies folder in my main user folder. This is setup to be a shared folder and is accessed as an SMB share with my media streamers.
Apple was apparently fixing a security issue related to symbolic links but killed the ability to set up and use symbolic links like I need them for my home network media streamers.
To fix do the following:
Fixing the symbolic link issue with Samba/SMB access problem in 10.6.4
 * Open smb.conf on the samba server in your favorite text editor
put the following in a terminal window:
sudo nano /etc/smb.conf
 * Find the global samba settings section under [global] and edit the following line:
wide links = no
change to:
wide links = yes
This enables access to symbolic links.
nano is a text editor for the terminal. Use the arrow keys to get to the word no in the above string delete no and type yes.
The control-x to exit and you will be asked to save the file.
Hit return to save the modified file, do not choose any of the save options.
For the terminal editor nano, control is the modifier key in dialogs that looks like a upside-down-superscript v.

The dangers of robocopy and symbolic links

I was backing up a laptop to a USB drive overnight, using robocopy to copy the directory structure of C:\Users on a Win 7 Pro build. The process ran all night. By the next morning, the copy had failed due to insufficient space on the drive. The data being
backed up was only 120 GB and the drive was an empty 500 GB. According to the log, the process only made it about 20% of the way before it got caught in an endless loop of copying the C:\Users\<username>\Application Data link. I had forgot to include
the /xjd switch in the job file it seems.
Unfortunately, now I am unable to delete the "Application Data" folder as I get a "...filenames are too long for the destination folder..." error. Upon inspection, the folder appears to point to itself, creating a seemingly endless subdirectory
tree. I've tried manually deleting parts of the directory structure through cut, paste and delete operations but I gave up after 2 hrs. I then tried writing a batch script using robocopy to mirror an empty folder, hoping that would remove the "Application
Data" folder, but that too fails after a few minutes once the directory path gets too long.
I've checked online but haven't been able to find any tool which would allow me to delete the circular link that was created by robocopy. Does anyone have suggestions on how to remove this file structure besides formatting the drive?

From all the other threads I've read, I'm beginning to realize this just isn't an option with this O/S.
Thanks for the help and suggestions.
I got intrigued by this problem, then spent a couple of hours on finding a solution. You can use the batch file below to deal with your circular folder. It will deal with any folder, no matter how deep.
@echo off
goto Start
This batch file will delete circular directories that are
created by robocopy.exe when used without the /XJ switch.
The batch file will warn you before it deletes any folder.
Pressing Ctrl+C will terminate it.

How can I stop from getting the "Firefox is already running" error message when trying to open links and FF has already been opened through a symbolic link?

I use symbolic links and program shortcuts as a way to easily open different Firefox profiles ie. one for casual/personal use and another for work. This works well, but I get the "Firefox is already running, but is not responding" error message if I try to open external links with FF as my default browser. FF is actually open and running fine, but I guess it doesn't acknowledge this fact because of how I'm originally starting the process.
I wasn't able to add the symbolically linked executables to the default program pane. Is there a way to bypass this error or other way to fix this?
The solution to the question linked below is what I'm using to open the different FF profiles.
http://superuser.com/questions/255312/pin-same-app-multiple-times-in-windows-7

hello, this is probably happening when you run the default profile with the -no-remote switch.

Does Java/JVm have a way to ditinguish between real files and Symbolic link

Hello guys,
I am using java.io.File.listFiles to list files in a directory. I have a symbolic link in the directory. the "listFiles" listing symbolic file contents too. As the real directory Symbolic link pointing is huge, the application taking too much time to load. is it a normal behaviour? are there any work arounds?

Short version: If getCannonicalPath() and getAbsolutePath() return different values, then the file you look at is a symlink.

Symbolic linker ssd and hdd

I have a macbook pro 15 inch mid 2012 (not retina) with Mountain Lion and Bootcamp Windows 7 Ultimate both stored on main bay SSD. I replaced my superdrive with the HDD and have an external superdrive. Was wondering how to Symbolic Link both OS from SSD to HDD. SSD Intel 520 180 GB is filling up fast but HDD has plenty of room 750 GB. Also i have norton on Winows 7 patition do i now need norton for osx as well? Dont want to lose the speed of SSD but am about to give up and put HDD back into main bay. Any ideas would be great Thank you -)

Can I use Unix symbolic links between Mountain Lion and Snow Leopard Mail folders?

After upgrading to Mountain Lion, I partitioned my iMac HD to have two partitions: Macintosh HD has Mountain Lion; I reinstalled Snow Leopard on Macintosh HD 2. Best part: you can access your user-created files from EITHER disk partition. But not so OS X Mail. I wanted to revert to Snow Leopard, since I don't like the iOS-like Mountain Lion (swipe THIS!), but Mail is a problem since all my Snow Leopard Mail was successfully migrated over to Mountain Lion during upgrade.
Is there a way to use Unix symbolic links between actual OS X Mail folders in Mountain Lion and OS X Mail in Snow Leopard?
It seems the (trial) symbolic link created pointed to a blank file.

It's not a matter of "letting" each maintain its own database, William. By default, I believe, I have no control over what gets written. In fact, if there were a way to set a preference that says, use this index named "spotlightindexSL' only [while in SL], that might solve my problem. Then when booting up in ML, it would just go after the index it last made.
My guess is that while I am in ML or SL and not the other, there are all sorts of changes to files and the system freaks and says "Oh, now look at what a mess I've made — there are all sorts of files unaccounted for. Now I have to rebuild the whole thing."
I have 2 had drives in my Mac, both 500GB. One (Working Disk) has no operating system and all my files, and the other drive is partitioned 470/30gb with SL on the 470 and ML in the 30. When I restart in either OS, the auto-start Indexing as if for the very first time, and do both hard drives (in total: 3 partitions of files, not counting the ML Restore partition).
I know it all uncoventionally — just wanted to see what my $20 new OS will cost me in software upgrades, in particular my $1800 Adobe Design Suite CS4 and a few others.

"/usr/lib is not a symbolic link" and testify+libjpeg7 problem

everytime I update pacman or do a "ldconfig" I get this:
/sbin/ldconfig: /usr/lib/ is not a symbolic link
this appeared by the time i installed libjpeg7 from aur (though I'm not 100% sure libjpeg7 is responsible). I've looked through google trying to find out what it means and if it is a problem, but nada! but, while at libjpeg, even though I installed libjpeg7 I can't compile testify (spotify linux-client). I get this error:
In file included from image.c:31:
jmemsrc.h:26: error: conflicting types for 'jpeg_mem_src'
/usr/include/jpeglib.h:959: note: previous declaration of 'jpeg_mem_src' was here
make: *** [image.o] Error 1
make: *** Waiting for unfinished jobs....
when i make /usr/include/jpeglib.h link to /usr/include/libjpeg7/jpeglib.h the compile and install is successful, BUT, testify crashes telling me:
Wrong JPEG library version: library is 80, caller expects 70
if more info's required, I'll provide andif I'm raising a problem already raised (I know there's been a lot of hassle since the upgrade), I'll gladly follow a link to solution.
edit: the "not a symbolic link" appeared after installing libspotify0.0.3. installed it on another computer, and same thing appeared. though, would still like to know why it appears...

Issue with stat() and symbolic links

Has anyone experienced the following issue with stat() ?
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
int main( int argc, char **argv )
struct stat buf;
if( argc < 2 )
return 0;
char *link = strdup( argv[1] );
if( stat( link, &buf ) == -1 ) {
puts( "Error" );
return 1;
if( ( S_IFLNK & buf.st_mode ) == S_IFLNK )
puts( "Is link" );
else
puts( "Not link" );
return 0;
If you compile and run the above code (or similar code), you would expect it to report that the given argument is a symbolic link when indeed the argument is a symbolic link; though, instead of the expected happening, the following happens as shown below:
$ gcc -o islink islink.c
$ ln -s /tmp link
$ ./islink link
Not link
$
Is anyone else experiencing this? My filesystem is ext4. The same error happens when using the S_ISLNK() macro.

man 3p lstat
DESCRIPTION
The lstat() function shall be equivalent to stat(), except when path
refers to a symbolic link. In that case lstat() shall return informa‐
tion about the link, while stat() shall return information about the
file the link references.

Windows 2008 symbolic links and SAP

Dear Gurus.
Is it supported to use windows 2008 symbolic links for sap directories?
For examle disk E: is small local disk and "sap" folder is symbolic
link to network share ?

Hi,
As far as I know it is not possible in Win 2008. Check below link & see if you get any important information.

Clustering, unix symbolic links, and war files

          Hello,
          we use symbolic links in our web application to a large shared storage device.
          This works when running a single server, when the application is not a war file.
          When we cluster the application, the admin server creates a war file, blindly
          follows the symbolic links and tries to include all files in the shared storage
          device. Bad!
          Is there a work-around to this problem in a clustered configuration?
          -Thanks-


          hi,
          can you tell me know you deploy your app to the cluster member
          manually? do you run each member as an admin server? how do
          you group them into a cluster then?
          thanks,
          yan

Networked Drives and Symbolic Links in Mavericks

So I have tried this a few times on my own... and I ended up deleteing all my contect with sudo in terminal..... I have everything restored now... but before I proceed, i thought I would get some help from those that know alot more...
Here is the scenario.. I have a MBP Late 2013 with mavericks installed.. I have a Networked drive at smb://192.168.1.1/ that is mounted and and accessable through finder no problem, and I have it set to reconnect at login so its always there.... there is no permissions for the networked drive its accessable to everyone... I want to take my itunes music and put it on the networked drive at smb://192.168.1.1/Music and have itunes access it from there like it was on the local drive.... so I started reading up on symbolic links
I have had no luck with ln -s in terminal, i keep getting told the directory doesnt exist... this is the exact line i have been triying [ln -s smb://192.168.1.1/Music ~/Music/iTunes/iTunes Media/Music] i thought it may have been a permission issue hence my ussage of sudo... but because of my ignorance I just ended up deleting everything..... what am i missing or doing wrong... someone please help!

Just for some clarification...
A simple saying that someone told me ages ago... "root is God"
When you use the sudo command you are doing the command as root. The "rm" command means remove, the "-r" means that you want the command to be done recursively so it will do the same command in any nested folders, and the "f' means to force the command.. even if it has any errors or is a file that root knows that you shouldnt do a command on..
So basically you told god to remove everything in your music folder, no matter how deep its nested, even if doing so would be immoral and against gods better judgement.

Ie 11 fails with 'IE Security detected that the URL and the configuration link to not match

HI,
I Have a user that is using IE 11 and is getting the following error:
IE Security detected that the URL and the configuration link to not match. Please use the URL as configured. Is and IP based URL. On IE 10 we get a similar message, but as soon as we add it to our trusted site and switch to compatibility
mode the issue goes away.
For example http://10.10.10.180/xxx/iafwebsite_810/
What would be causing this issue?
Any help would be appreciated.
Thanks,
Trish

Hi,
It seems that this URL doesn't meet security level. Thus, as long as you add this URL to Trusted sites zone, this issue is fixed.
Thanks!
