[solved] /var/run/dbus/pid

After Crashing my System with the kernel Update Yesterday, I set up a new clean Installation. I got now this error message at the start up screen.
Failed to start message bus : The pid file "/var/run/dbus/dbus.pid" ...
I don't understand what I have to do!

@Doehni
You give me the Idea! Thank's a lot
no how I solved the problem
vi /etc/rc.conf
before
DAEMONS=( hal dbus ........)
then changed to
DAEMONS=(...... dbus hal ......)
and the problem was solved

Correct entry for /var/run/slapd.pid

what is the correct pid for slapd?
my os x did not come with slapd.pid so I'm
trying to create one manually, but I don't
know what I'm supposed to use.
also any one know the correct entry for
/var/run/slapd.args?
Thanks,

When slapd is running it saves its pid in the file /var/run/slapd.pid
This allows other processes to find its pid to use to communicate with it.
You do not need to create this file.
also any one know the correct entry for
/var/run/slapd.args?
Similar to above, this is created by slapd. You don't need to worry about it.
The better question is why is slapd not running (assuming your machine is set up to be an OD Master).

/var/run/gdm.pid doesn't exist, perhaps GDM isn't running
I'm getting this message when I'm trying to turn off deamon manualy. There is a file in /var/run/ called gdm.pim . It's started after gnome upgrade. What's wrong with this ?
Thanks for your help

I do not start dbus manually anywhere on my system except for launching lightdm and thermald through a systemd service.

I will mark this as solved for now. In order to minimise the running dbus sessions, I switched back from ldm to startx and also removed the pulseaudio autostart from /etc/X11/xinit/xinitrc.d/ since I want to control myself when pulseaudio starts the dbus sessions.
This is how it looks now with X running and udisks2/gvfs enabled dbus session.

GW POA Can't write .pid file to var/run/novell/groupwise

I'm running GW 8.0.2 HP2 on SLES 10, and just recently figured out after trying to set up a CRON job that I can't restart my POA without rebooting the server. When I run a rcgrpwise status, the POA shows as "unused." Running rcgrpwise stop or restart fails to stop the POA, though the domain goes up and down with no issue. I've checked my gwha.conf file, and everything appears to be in the correct case, and referencing the correct locations. The domain can create its .pid file in /var/run/novell/groupwise just fine.....
I've read and followed the directions in the tid 7003322 (which sounded like a direct match for this issue), but when I edit the header for the POA an rcgrpwise status returns that it is "unable to check [@gw4post.poa]"
The forum thread titled: "rcgrpwise status shows "unused", but it is running." also sounds like the same problem, but there was no resolution.
Anyone have any ideas? Please let me know if I can provide any further informnation - I'm writing this at 0-dark-30 and probably left something out....
Thanks,
Stacey

Okay, so your stuff looks good.
Yes, when the system boots it's supposed to basically load/fire up the rcgrpwise script (more or less, but it reads the gwha.conf file)
That is quite odd that if you bounce the server, it's fine.
Greg is correct that the PID file(s) get written to the directory where your log files are at.
Do you know where you log directories are at for the MTA/POA?
They should be in diff. directories.
Brief section from the docs:
If you selected Launch GroupWise Agents on System Startup in the Installation program, the Installation program configured your system so that the agents start automatically each time you restart your server. The Agent Installation programs always creates a grpwise startup script in /etc/init.d for starting the agents, as described in Starting the Linux GroupWise Agents as Daemons. To enable automatic startup, the Agent Installation programs also create symbolic links named Snngrpwise in the rc3.d and rc5.d directories so that the agents load on restart into level 3 or 5, depending on the configuration of your Linux system. The value of nn is determined by the chkconfig command during installation so that the GroupWise agents are started in the proper sequence with other processes running on the server.
When the grpwise script runs and starts the GroupWise agents, the agents read the agent startup files in /opt/novell/groupwise/agents/share to check for configuration information provided by startup switches. Because the --show switch cannot be used in the startup files, the agents do not run with server console interfaces when started automatically when the server restarts, unless you modify the gwha.conf file as described in Enabling the High Availability Service for the Linux GroupWise Agents.

/var/run symlink replaced by directory after reboot

Hi guys!
I have installed Arch on my home server a few days ago using the latest (2012.06) iso available (not the net install).
My boot, root and swap partitions are all mdadm raid 1 and i use syslinux to boot which works fine.
After setting up my machine for a while i noticed the "filesystem" package was not properly installed by pacstrap (even though it's already pretty old and should be included in the latest iso). Don't get me wrong it WAS installed, but only the /var/lock directory was symlinked. As most of you know this package update should replace /var/run and /var/lock with symlinks.
So i just tried to "reinstall" this package with 'pacman -S filesystem --force' (as described in the news post).
At first it looked great - symlinks were there and i could start several services with systemctl (which didn't work for a lot of services before), but get this:
After every reboot or simply after some time the symlink (just of /var/run , not lock) was GONE and a file (not directory) "run" gets created with the following permissions - -rw------- root root. What happens is that at every reboot systemd-logind dbus and therfor most other stuff won't get started properly. For example after boot i had only just the terminal at F1, all other screens were just black and after some time i get the message that systemd-logind.service failed.
When i manually remove the file and replace it by the symlink i can manually start/restart all services and from that time on everything works great.
What i was interested in was WHAT exactly removed my symlink after some time or at boot time, so i used audit to monitor the symlink for a while.
Here's what i got when the symlink was removed and then a file "run" was "touched": http://pastebin.com/BYsRHWbC
Unfortunately the ppid ( i guess "parent process id") was not running anymore so i still don't have any idea what's going on exactly.
I'd appreciate ANY information or tip you have. My guess is that systemd is involved somehow.
As a sidenote: Before i found out the symlink was missing i installed initscripts once to see of systemd was just still buggy. I removed it shortly after though.
Looking forward to input and I'm happy to answer your questions.

Isn't Shorewall is just a collection of scripts that load iptables rules? Even the Shorewall binary is just a shell script, so you can easily `grep` through it and the config/helper files that make up Shorewall to see what it's up to.
Looks like the only time it messes with `touch` is here:
root@antec /etc/shorewall# grep -R touch /usr/share/shorewall/*
/usr/share/shorewall/prog.footer: touch $STARTUP_LOG
/usr/share/shorewall/prog.footer: [ -n "$SUBSYSLOCK" ] && touch $SUBSYSLOCK
/usr/share/shorewall/prog.footer: [ $status -eq 0 ] && touch $SUBSYSLOCK || rm -f $SUBSYSLOCK
/usr/share/shorewall/prog.footer: [ $status -eq 0 ] && touch $SUBSYSLOCK || rm -f $SUBSYSLOCK
So.. maybe your shorewall.conf file has set SUBSYSLOCK to something invalid, like /var/run, and it's wiping it out each time when it checks for the PID lock file?
I was able to get Shorewall to run and put its PID file in SUBSYSLOCK=/var/lock/shorewall
It didn't mess with /run or /var/run at all.
Had to change the systemd 'shorewall.service' file quite a bit though. It's not correct at all.

Can i run two PIDs at the same time?

Hi
I want to control speed of the rotating shaft and force applied by the pneumatic cylinder using two different PIDs from the same program.
I managed to get two PIDs to work separatly using PID control loop VI`s supplied with labview 6.1 (I got Kc, I and D right, so there is no overshoot). When I try to run both PIDs within my vi they don`t work. I again tried various gains and managed to get one PID to work but not the other. Then through trial and error I managed to get a second PID to work but I had to change refresh time of the FOR loop from 100msec to 1msec.
Does anyone have experience with running two PIDs in the same program? Does the timing of the FOR loop influence PID contorller? Does equiring of other data while
running PID has effect on the PID?
I would really appreciate any comments/help. I am pretty thrustrated at this time
Thanks

I don't know whcih PID vi's you are using but I had similar problems. I
solved it by going to the VI properties of the PID subvi, select category
execution and make sure that reentrant execution is selected. Only then two
instances of the PID vi can run without interfering each other.

Database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2) on mac os x 10.9.2

Dear Fellas:
I received "database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2)" on mac os x 10.9.2.
mysql info:
ps -ef | grep mysql
    0    66     1   0 11:06AM ??         0:00.04 /bin/sh /usr/local/mysql/bin/mysqld_safe --user=mysql

Please help!!

Fascinated and guessing:
Something related to sock(2) because that's not part of your copied info. I'm thinking you've doubled up on sockets and the second socket doesn't exist, meaning you should be connecting to the first socket "mysqld.sock" whether automatic or not.
I've only used GUI tools on purpose, so does this mean you've already got MySQL running and you tried to launch it again manually? Perhaps you already have one instance of a db and you're trying to launch a second instance, and the two can't coexist with a single user local db?
Assuming this is all local, I'd shut down the db service and restart it, out of hand. I've seen similar messages when I set the db to start up on boot, and it didn't finish shutting down when I tried to restart it manually. Usually the GUI won't let me turn it on because it reports it's already running, but in that case it hadn't finished performing what the GUI was reporting.
Just speculating.

The timing of the FOR loop will influence your PID control, which is a fundamental part of PID control. Acquiring data doesn't affect the PID although it could affect the timing of the loops. For instance if you only have one DAQ card you would want to have it all in one loop because you can not have two AI sessions open to the same card.
For more detailed information on PID I would recommend reading the "PID Control Toolset
User Manual" which should have been installed to your machine but can also be found at : PID Control Toolset User Manual"

Error: Can't connect to auth server at /var/run/dovecot/auth-master: No su

Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory
error showing up, there is no auth-master file in /var/run/dovecot
this has just happnened over night
any ideas how to re-install dovecot
google search goes on about linux but barely any info about max osx server

auth-master is created when you start the mail service. Deleted if you stop the mail service. If that is not happening, you may have to re-install mail. Dovecot is the IMAP/POP part of the mail service. I am not sure what happens if you disable IMAP. I am guessing it is not there. But that is the extent of any tips I can offer. I suppose you could reinstall, but that seems a bit extreme to me.

Shared memory in /var/run instead of /tmp

I use shared memory segment on a diskless node.
This shared memory segment are stored in /tmp.
Is there a way to put them in a "memory based" directory, as /var/run (solaris 8) instead of
the disk-based directory

My problem was especially to change toe location
of the shared memory on file system. I succeed
with FIFO but not with shared memory. I
don't find any solution.
concerning the definition of memory base vs. file
based I have no clue but the following extract from
docset
------[Extract from solaris 8 documentation]-----
The /var/run File System
A new TMPFS-mounted file system, /var/run, is the
repository for temporary system files that are not
needed across system reboots in this Solaris release
and future releases. The /tmp directory continues to
be repository for non-system temporary files.
Because /var/run is mounted as a memory-based file
system rather than a disk-based file system, updates
to this directory do not cause unnecessary disk
traffic that would interfere with systems running
power management software.
The /var/run directory requires no administration.
You may notice that it is not unmounted with the
umount -a or the umountall command.
For security reasons, /var/run is owned by root.

/var/run/name_service_door - zones stuck in single user mode

Hello,
I have two Sol10 boxes - e4500 & x86. Both have multiple zones configured which have been working for quite a while. I was enabling audit logging on these machines (perzone) which required a reboot.
After a reboot, the zones won't come out of the singleuser milestone. Trying to ping the global zone by name (nsswitch is files, dns), it hangs. A truss reveals:
open64("/var/run/name_service_door", O_RDONLY) = 3
fcntl(3, F_SETFD, 0x00000001) = 0
door_info(3, 0xFF16F7A8) = 0
door_call(3, 0xFFBFD790) (sleeping...)
and hangs forever.
I threw the latest patch cluster at both and it had no effect.
Each zone has a /etc/sysidcfg, /etc/.NFS4inst_state.domain, and proper nsswitch.conf/resolv.conf that had been working (rebooting) until I tried to enable auditing. This happened a while ago and a total uninstall/reinstall of the zones fixed the issue.

Hi, snikpmup.
Your panic log cites a page fault:
panic(cpu1 caller 0x001A3135): Unresolved kernel trap (CPU 1, Type 14=page fault)…
This is a common fault type, indicating the processor could not access either data memory or the next instruction to be executed. Potential causes include RAM problems, hard disk corruption, and programming errors.
The panic log you posted is incomplete, so there's not much else to say based on what you've posted. I do note some messages prior to the panic indicating M-Audio devices: you might want to check with those folks re: Mac Pro compatibility, any necessary updates, etc.
I suggest following the full set of troubleshooting steps cited in my "Resolving Kernel Panics" FAQ. The FAQ includes step-by-step instructions for identifying and resolving some of the most common causes of kernel panics. The FAQ is a roadmap: start at the beginning and work systematically through the end, i.e. the "If all else fails..." section.
Good luck!

     for a while, one of my 10.6.8 servers looses its DNS adresses at each reboot and put the old adresses instead.
      When I change it in System Preferences, /var/run/resolv.conf is OK, but after reboot this file is generated with old values.
      NOTE : since last week, it changes them when it is running .
     Any idea would be very appreciated.
Regards,
Joan

Hi dmare,
     thank you for your reply.
     I do not modify resolv.conf directly, I modify DNS IPs in System Preferences > Network which modifies resolv.conf.
     I do that to put correct DNS IPs.
