/tmp vs /var/tmp

I am running Solaris 8, updated to latest patches. When I create Posix message queues or semaphores, the corresponding directories (for example, .MQD and .SEMD) are created in /var/tmp. On all the other machines we have these are created in /tmp. I would like to change this location so that they are created in /tmp. This would help with some permission problems. I have been told that there is a patch to set this up properly, but I updated with the latest Solaris 8 recommended patch set last night, and things haven't changed. Is there some other patch I need or is there a different way to fix this? Thanks.

I don't think there's a good reason for it, at least not one that outweighs the problems.

/var/tmp not getting cleaned out...

This might not exactly apply to the Finder, Dock or Dashboard but it is file maintenance, and I don't see a closer match.
I've noticed that my /var/tmp directory has a lot of files that are pretty old. There's 3 directories there that seem to be written to daily...those I wouldn't touch... But there's a whole bunch of files that are named things like: 4568943754a6d... around 56M worth each is ~1.5M
Why are these not getting automatically cleaned up? Is there a limit to this directory that could be causing me issues. I have several but I don't dare mention them here for fear of being told to open a new post
Thanks!

Hi again
does the '3 days ago' actually set the time? so '1 week ago' would be valid too?Ah, was afraid you might ask that
'3 days ago' does "set the time" as you say. '1 week ago' might work, but the man pages are not particularly helpful on what works and what doesn't. The find man page refers you to the cvs man page, which says:
However, cvs currently accepts a wide variety of other date formats. They are intentionally not documented here in any detail, and future versions of cvs might not accept all of them.But that gives an example of "1 hour ago" being valid, so I tried a few variations
wacking whole directories scares me... especially since there are live directories in here that I think shouldn't be deleted... can I take this part out?Yes, you can leave out the complete second "find" command if you wish. But applications shouldn't leave files or folders lying around in /tmp or /var/tmp and expect them to still be there when they come back!
excuse my ignorance what language is this?This is the Bourne Shell or more accurately bash. You can try reading the man page, but if you're interested I think you'd find an introductory shell scripting book a lot more readable!
My weekly hasn't run since Nov 18th but the Monthy and daily both say Dec 1st!!!No problem. My weekly hasn't run since Nov 15th. It will eventually get run, after about a week of cpu time (not sleeping).
Now that the periodic scripts are managed by launchd, rather than cron, they do eventually get run. Unless you are running a busy server with hundreds of users, rotating the log files is no big deal with today's typical disk sizes.

Automounting EncFS encrypted /var/tmp using pam_encfs

I've encrypted /var/tmp using encfs and tried to set up automounting using pam_encfs, following the instructions at https://wiki.edubuntu.org/EncryptedHomeFolder, linked on the Arch Wiki. Basically, what I've done is the following:
1. Install pam_encfs
2. Insert the line "auth sufficient pam_encfs.so" into /etc/pam.d/login and append "use_first_pass" to every subsequent line (see below)
3. Change the source and target in am_encfs.conf to /var/.tmp and /var/tmp, and change "allow_other" to "nonempty"
4. Add fuse to the modules array in /etc/rc.conf
5. Add myself to the fuse group
6. Run "sudo encfs /var/.tmp /var/tmp" and set it up with the default options and my login password
When I restart and login, however, /var/tmp is not mounted. I can manually mount it with "sudo encfs /var/.tmp /var/tmp".
Here is my /etc/pam.d/login:
#%PAM-1.0
auth required pam_securetty.so
auth requisite pam_nologin.so
auth sufficient pam_encfs.so
auth required pam_unix.so nullok use_first_pass
auth required pam_tally.so onerr=succeed file=/var/log/faillog use_first_pass
# use this to lockout accounts for 10 minutes after 3 failed attempts
#auth required pam_tally.so deny=2 unlock_time=600 onerr=succeed file=/var/log/faillog
account required pam_access.so use_first_pass
account required pam_time.so use_first_pass
account required pam_unix.so use_first_pass
#password required pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3
#password required pam_unix.so sha512 shadow use_authtok
session required pam_unix.so use_first_pass
session required pam_env.so use_first_pass
session required pam_motd.so use_first_pass
session required pam_limits.so use_first_pass
session optional pam_mail.so dir=/var/spool/mail standard use_first_pass
session optional pam_lastlog.so use_first_pass
session optional pam_loginuid.so use_first_pass
-session optional pam_ck_connector.so nox11 use_first_pass
-session optional pam_systemd.so use_first_pass
and my /etc/security/pam_encfs.conf:
#This file is parsed top to bottom, until the first mount line that matches is found, then it stops.
#Note that I dont support spaces in params
#So if your for example gonna specify idle time use --idle=X not -i X.
#If this is specified program will attempt to drop permissions before running encfs.
#(will not work with --public for example, as that requires encfs to run as root)
drop_permissions
#This specifies which options to pass to encfs for every user.
#You can find encfs options by running encfs without any arguments
encfs_default --idle=1
#Same for fuse, note that allow_root (or allow_other, or --public in encfs) is needed to run gdm/X.
#you can find fuse options with encfs -H
fuse_default allow_root,nonempty
#For a mount line, - = generic, we try to fill in what we need.
#A Mount line is constructed like this:
#USERNAME if "-" or "*" gets replaced with $USER
#SOURCE if USERNAME is -, replace with path + /$USER
# if USERNAME is *, replace with $HOME/ + sourcepath
#TARGET PATH if - replace with $HOME
# if USERNAME is *, replace with $HOME/ + targetpath
#ENCFS OPTIONS encfs options here is encfs_default + encfs_options
#FUSE OPTIONS encfs options here is fuse_default + fuse_options
#Keep in mind that the configuration file is parsed top to bottom, so if you put your generic line on top,
#that will always match before any custom lines under it.
#In this example, with example_user uncommented, the "-" line will never be parsed if you login as example_user.
#In the lines with the USERNAME "*", all paths are relative to $HOME
#USERNAME SOURCE TARGET PATH ENCFS Options FUSE Options
#example_user /mnt/enc/example_user /home/example_user -v,--idle=1 allow_root
#* .private private -v allow_other
- /var/.tmp /var/tmp -v,>/home/ian/log nonempty
The ">/home/ian/log" option at the bottom was an attempt to direct the output of the command pam_encfs runs to a file, but it didn't create a log file when I tried it. If anyone knows how to do this correctly, that would probably be pretty helpful, since it's difficult to debug without knowing what's failing.
Thanks in advance for any advice.

I think I figured it out. It is indeed a configuration issue.
I found a post on the internet where someone suggested putting the items I had added to /etc/pam.d/system-auth in /etc/pam.d/system-login instead. I also read the documentation for PAM linux (http://linux-pam.org/), as previously I had only been reading the documentation for pam_mount. Then, by looking at all of the files in /etc/pam.d/ I figured out what was going on.
I turns out system-auth is just used by too many other services. In particular, I believe it was the use by the systemd-user service that was causing an issue in this case.
The catch was that system-login is also used by systemd-user, so even that probably wouldn't have fixed the problem.
What I ended up doing was creating a new file that contained only the pam_mount and pam_ecryptfs lines I had added to system-auth previously. Then I modified system-local-login and system-remote-login to include that new file.
I'll also need to make some modifications to the appropriate file for the graphical login manager when I set that up.
Marked thread solved in case this helps anyone else in the future.

Firefox opens links from file:///var/tmp/

Using kdemod with Firefox set as default browser, when I click a link in Kmail, an IRC client, or Kerry Firefox doesn't go out onto the internet it opens the link from the address file:///var/tmp/*. At some point the computer is retrieving text from the internet and creating the tmp file, but I get a really ugly page with no images at all and a really poor layout.
This only affects my login. I've compared the entries in the Control Center --> KDE Components --> File Associations for html between logins and everything seems to be setup the same. Any ideas what could be going wrong?

what about kcontrol > kde components > components chooser > web browser? Is that set to your preferred browser?
*edit*
After re-reading your post I am not sure if the above has anything to do w/ it.

/private/var/tmp has gone missing! ***?!?!?!?

Please, I need help on this one. I had an iBook G4 crash on me, then get as far as the white Apple screen with pinwheel before freezing. I tried running Disk Utility off of an OS X install disk, and it found no volume structure errors. However, when I tried repairing permissions on it, Disk Utility was reporting that the directory /private/var/tmp has gone missing, and it could not repair permissions.
What gives? How can the whole directory get fried? How can I replace it? I've already tried doing an archive and install, but the OS X installed won't let me do an archive and install, probably because this folder is missing.
Can anyone help?

Get Prosoft Data Rescue to recover the data to an external hard disk. Shut down the computer, disconnect the drive any other third party peripherals and then next after that do an erase and install of the operating system. You will probably want to use a CD burner to burn off less frequently used data on occasion at least a couple times so that your hard drive does not fill up with unessential stuff. Some more tips on backing up are on this page:

Upgraded to Mavericks - System errors popping up in /private/var/tmp ... Help!!

Hi there,
Ever since I upgraded to Mavericks, and installed my standard software, I'm getting some odd behaviour.
Every so often (no discernable pattern so far) my Finder pops up with a new window in /private/var/tmp. There is a huge system stacktrace printed out in a file with the following format: "
sysdiagnose_2013.10.30_19-53-16-MDT_9956.tar.gz
There are a ton of files in there, so I have no idea how to figure out what is crashing and causing it. I get no "system crash message" to go along with it.

Clearing of /var/tmp/logs

Hi all,
Until now..we are clearing the logs manually by
find /var/tmp -name '*.dbg' -mtime +0 -exec rm {} \;
Now...needed to write a script..when ever the /var/tmp mount point reaches a threshold of 90% the above command should fire...
How can i do the above...
thanks,
baskar.l

Removing those logs is usually done not by database, but by OS commands, manualy or automatic.
The best thing for you would be to write simple shell script, place it in the cron and schedule execution intervals based on you instance activity.
You will need few variables in that script , one of them will propably be for holding the value got from os specific disk usage command and one for
holding your desired treshold value.
Then you could use if-then-else logic to compare those two values through those two variables and when matched execute your removal command.

Does that have something to do with it?

Aurbuild saying "package not found under /var/tmp/aurbuild/pkgbuilds"

Hello everyone
I am using aurbuild for installing aur packages. Since some time now, I keep getting the error message:
package not found under /var/tmp/aurbuild/pkgbuilds
For example the exact message is:
lib32-pciutils not found under /var/tmp/aurbuild/pkgbuilds
No result found
What can I do about that?
Thanks in advance
b1

Please see our Forum Etiquette regarding bumping b1: https://wiki.archlinux.org/index.php/Fo … te#Bumping
Have you tried if the same thing happens with other packages and AUR-builders?

Hey WD... Y'all's got a BUG... When I access the MyClod from my laptop running XP with FireFox, I get the thousands of "sess_*" files written to /tmp, and I get groups of messages of the form Jul 14 22:36:26 WDMyCloud REST_API[23951]: 192.168.1.101 ORION_LOG /var/www/rest-api/api/Auth/src/Auth/User/UserSecurity.php ISAUTHENTICATED [ERROR] Authentication failure for /api/2.1/rest/mediacrawler_status?_=1436938574613

But when I access it similarly from the desktop machine, also running XP with FireFox, I just get *one* of the "sess_*" whatever files written to /tmp, and just one set of messages of the form Jul 14 22:40:26 WDMyCloud REST_API[24325]: 192.168.1.100 OUTPUT DlnaServer\Controller\Database GET SUCCESS

Jul 14 22:40:51 WDMyCloud REST_API[23952]: 192.168.1.100 OUTPUT Alerts\Controller\Alerts GET SUCCESS written to /var/log/user.log. So the MyClod is playing nice with some computers and not others... My guess is this could be happening more than WD knows about and could be producing all manner of mysterious behavior, since not only does it only happen on some machines but it does *not* crash the MyClod - at least not right away. The main effect is to fill /tmp and /var/log with garbage so nothing can write to them, which will probably affect some things and not others... https://www.youtube.com/embed/2Gwnmb6P-3k

Is it safe to delete .appmergegen files in /var/tmp anytime?

Hi,
I saw when I start an weblogic server, it writes deployment files in /var/tmp in exploded format.
Do anybody has any idea on these files? and why weblogic writes these in /var/tmp?
And can these be deleted anytime without restarting weblogic?
e.g. here are some of the files generated today:
(each of the directory contains deployment files in exploded format)
drwxr-xr-x 5 ecmspbea ecmspbea 512 Sep 14 07:29 .appmergegen_1222796450487_da.war
drwxr-xr-x 9 ecmspbea ecmspbea 512 Sep 14 07:42 .appmergegen_1252939053427_da.war
drwxr-xr-x 3 ecmspbea ecmspbea 512 Sep 14 07:42 .appmergegen_1252939053427
For background:
This is weblogic 10.0 on a Solaris 9 box.

Thanks for your answer.
But I am curious to know if these are not required at all after deployment is successfull, why weblogic does not delete these? It is going to be an overhead to the administrators to periodically delete these files from /ver/tmp or to write scripts ... whatever ...
I'll delete all such files from /var/tmp. but needed a confirmation that weblogic server not at all access these during runtime (means we do not need to restart weblogic servers after deleting all these) ...
Appriciate your help.

/private/var/tmp running full with cache

We're importing a lot of JPEG and Photoshop pictures and in a big job the folder /var/tmp (locally on the FCServer, who is also the only Compressor) is running full with cache files.
A lot of these:

As you can see, big files.. So big that the last 2 days my server startup HD filled almost full (1 GB left).
So it looks like FCServer is not cleaning up after his self. Can I do something about this? At least change the max caches size?
Thanks

Hi,
It was a corrupted PSD, one file corrupt all the other ones after that one also failed.... we removed the corrupt one and 'Analyze' all the other ones.
Problem solved??

No space under /var/tmp

Hi all,
I'm having difficulties in one of our Solaris 10 boxes. When I try to edit a file using vi editor it gives me a message saying no disk space in the /var/tmp. but it seems like sufficient disk space available since /var/tmp is mounted to root partition. see the output
5stac5(5.10):/var/tmp>df -k .
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/dsk/c0t0d0s0 10331209 6897631 3330266 68% /Please help me with this
Thanks,

Not specific. Even for a new file this error was given. However i've noted that large number of files created under /var/spool/clientmqueue. Is that can be a problem?

Sandbox deny file-read-metadata /private/var/tmp

Hi,
I have Berkeley DB 5.2.28.
And I tried to use Berkeley DB on iOS 4.3.
I wrote;
printf (stderr, "db open - 1");
ret = dbenv.open(strDBdir,
DB_CREATE |
DB_INIT_LOCK |
DB_INIT_LOG |
DB_INIT_MPOOL |
DB_INIT_TXN |
DB_THREAD |
DB_RECOVER,
S_IRUSR | S_IWUSR);
printf (stderr, "db open - 2");
I runned this app on iPod 4 (iOS 4.3), and then in xCode's Organizer found a message: "sandbox[363] <Notice>: myapp(362) deny file-read-metadata /private/var/tmp", between "db open - 1" and "db open - 2".
How to resolve it?
Please, help me.
Thank you.

Hi,
I assume you have correctly followed and built BDB 5.2.28 for Apple iOS by following the guide for Building Berkeley DB for UNIX/POSIX and the notes specific to Apple iOS (iPhone OS).
The error message you reported:
sandbox[363] <Notice>: myapp(362) deny file-read-metadata /private/var/tmpis not an error from the BDB layer, but rather from the OS layer. It could point to insufficient privileges or rights (to write in that /private/var/tmp directory) or maybe a profile / access control list that is not configured correctly to allow the user you're running under to read metadata and data for a file; for example, make sure you have something like this in your sandbox profile:
(allow file-write* file-read-data file-read-metadata
(regex "^/path_to_BDB_environment__strDBdir")
(regex "^(/private)?/var/tmp/")
(regex "^(/private)?/tmp/"))If this does not help then I suggest you post on the Apple discussion forums.
Regards,
Andrei

Wlappc defaults to /var/tmp

my wlappc task defaults to /var/temp directory to genearate the temporary jars. This could cause issues when two user tries to compile will use the same /var/tmp directory.
How can i set my prefered temp directory in wlappc task. Below is the wlappc task in my ant script
<wlappc debug="true" deprecation="yes" compiler="javac" verbose="yes" nowarn="yes" >
Any suggestions will be highly appreciated.
Thanks!
