[SOLVED] sshfs - Hangs at different occations (reboot needed?)

I'm using Thunar with gvfs and sshfs, both works fine and does the job.
Only problem is that for some reason, sshfs when going back to a folder after a while (that's bookmarked if that matters) nothing happens, and if i try to "unmount" the remote filesystem it hangs thunar.
I'm not quite sure which mount point to unmount so i usually go full out noob and reboot.
But here's my mount:
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
sys on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
dev on /dev type devtmpfs (rw,nosuid,relatime,size=8194272k,nr_inodes=2048568,mode=755)

Bha solved it (after living with it for weeks)...
ps aux | grep ssh
Just looked for anything suspicious and:
ssh -oForwardX11 no -oForwardAgent no -oClearAllForwardings yes -oProtocol 2 -oNoHostAuthenticationForLocalhost yes -l user -s host sftp
Just killed the correct pid.

Multiple users logged into one server, each users printer has a different name, application needs ONE name to print to.

Multiple users logged into one server, each users printer has a different name, application needs ONE name to print to.
I'm NOT in any way a Terminal Services expert and I need help trying to get an application program working in a multi-user environment.
The issue is that the printer changes for every user that is logged in. The application needs to print NOT to the default printer, but to a "special" printer which is selected in the application... let's call it a label printer to simplify the explanation.
You have your default regular printer, easy for the application to find that one, and then you have a special printer that labels get printed onto. The application needs to know what printer is the label printer. So we allow the user to select that in the
application and the selection is stored in a config file in
C:\ProgramData\mfgr\prog\setting files
I don't have access to the application so I can't change how this works.
In the "regular" world, selecting the label printer driver to use should be per machine, NOT per user. When a new user logs into a machine, the physical printer doesn't go "poof" and a new printer suddenly appear. Same printer for all
users.
Yet in terminal services, the physical machine is "merged" with the virtual machine on the server. And there can be many users logged in at the same time. So each users real machine (and real printer) is injected into the "fake" terminal
services machine. The name of the printers is made unique for each user. So the printers DO go "poof" and change names depending on the user logged into terminal services.
So user "A" logs in and sets up the application to print to "LabelPrinterForUserA" (or whatever the name of the printer happens to be), that setting is stored in the ProgramData subfolder, and all is well. Later, user "B" logs
in, and when they print, the application tries to print to "LabelPrinterForUserA" which doesn't exist for user B or is only accessible by user A. If user B re-configures, that breaks it for user A.
SOLUTION 1: The way that /should/ work (in my mind) is that you define one "generic" printer in Terminal Services... call it "Virtual Label printer" and when the user wants to print to it, the print job gets re-directed back to whatever
physical printer is actually connected to their local workstation. There is a map of virtual printer to actual printer depending on the current user. The application is told once to print to "Virtual Label Printer" for all users.
SOLUTION 2: Or... there should be some way to make the ProgramData sub folders separate per user. E.g. when user "A" tries to access:
C:\ProgramData\mfgr\prog\setting files
they actually get
C:\UserData\UserA\AppData\mfgr\prog\setting files
and user "B" gets
C:\UserData\UserB\AppData\mfgr\prog\setting files
So the question I have is: Does either of those solutions exist hidden somewhere in the setup of terminal server? Or is there another way around this issue that I don't know?

I don't really have a "for sure" answer to this, but because people here can't seem to deal with a question that hasn't been answered I'll provide the best answer I did receive from ServerFault.com user Nathan:
I can feel your pain with using old software on terminal servers ...the solution I've come up with definitely won't scale as it requires some manual configuration, but I've gotten this method to work with our label printers (which require to be
printed to an LPT port...yep, that old).
Share your USB-connected printers to the network on each machine. Then, have the user log in on aunique session for each of them
(a TS account cannot be shared among computers for this to work) and install a network printer pointing to the USB one they shared. Try to use a DNS name to account for possible DHCP movements.
After, it should work. Each user can do this since display names can be identical as long as the ports are different (which they are).
This was clarified by the following series of comments:
I think you are on to something here, and I originally advised the admin to do this. The problem he ran into is that it setup the printer names in the TS as "printer on usersworkstation"
and he could not rename it except to change the "printer" to whatever. E.g. the "on userworkstation" remained. I believe there is another way of installing the printer which avoids this, but I can't find it. Ages ago, one used to do NET
USE LPT2 \\computer\printer password /USER:domain\user /PERSISTENT:YES and then tell the driver to print to LPT2 –  James

@JamesNewton That's actually the exact method we used. The way around the "network printer" part is to install it as local printer and map it to a TCP/IP port that way. –  Nathan
C Mar
17 at 16:28
You mean in the case where the printers are TCP/IP connected and not local USB / LPT to the users workstation? That makes sense. Wonder if this will work for USB connected printers... –  James
NewtonMar
17 at 16:35
@JamesNewton You'd share the local printer on the client's PC then on the server connect via TCP/IP to it. You'd need static addresses or use DNS names if DHCP, though. –  Nathan
C Mar
17 at 16:51
Ah. Yes. I see. Looks like the LPT thing should work even with a USB connected printer:superuser.com/questions/182655/… –  James

Is it possible to load an instructional DVD with several chapters onto my iMac and then somehow access the different chapters as needed remotely on my iPad?

Is it possible to load an instructional DVD with several separate chapters onto my iMac and then somehow access the different chapters as needed remotely on my iPad?

The "TDMS Open" node does more than open a file handle, it will load meta data (including file/group/channels' properties) and create index structures in ram for fast accessing any raw data in TDMS file. Thus, my advice is:
1) You can save the efforts to write sub-VIs to preload properties of a TDMS file at least, since they are already kept in memory after the file is opened.
2) Since index structures are presented, the performance to read data of any part in a tdms file will not be affected by the file size and the read performance might already satisfy your application. You can have a try.

SEVERAL different iphoto libraries - need to consolidate

I have had a couple macbooks and now an imac. Have also done a lot of moving stuff around using drives/time machine etc. In short, I have a bunch of different iphoto libraries on various different drives and need to consolidate.
I am thinking of just exporting all photos in original format from each library onto one large drive and then importing onto one library then basically starting all over again getting them organized. I think I can then also more accurately weed out duplicates etc. I assume that the various different albums I have on the different libraries will not be kept and might lose meta data etc. But not sure how else to proceed.
Suggestions would be appreciated

What version of iPhoto?
With iPhoto '11 version 9.3 and Aperature 3.3 you can merge libraries in Aperature
Otherwise the only solution to merging is the paid version of iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -
Your exporting and importing merges teh photos but no versions, no metadate, etc

Iphone 4 hangs many times a day.needs to be switch off to reset.

iphone hangs a lot.it always needs to switch off to b reset.the problem started after updating to io7 .now running 7.0.4 with same issue.
any solution????????????'

Did you use a backup to restore the device after updating to iOS 7.0.4? What other user troubleshooting have you done except to power the phone off/on? The next step is a reset, holding the sleep/wake and home buttons together until you see the Apple logo and then release. After that is a restore from backup, then if needed a restore as a new device.

Different between Reboot Role Instance and Restart role

Can anybody tell the different between
Reboot Role Instance
http://msdn.microsoft.com/library/azure/gg441298.aspx
and
Restart Role
http://msdn.microsoft.com/library/azure/jj157197.aspx
are they redundant?
Even one is put under virtual machine operations, but virtual machine is also a role instance in a cloud service anyway.

When you reboot a role instance, the instance is taken offline, the underlying operating system is restarted for that instance, and the instance is brought back online. Any data that is written to the local disk is persisted across reboots. Any data that is
in-memory is lost.
Ref - http://msdn.microsoft.com/en-us/library/azure/gg441298.aspx
In particular to cloud services, - customizations done on the role instances e.g. manually installed software, deployed files (either through RDP or through web deploy) will be lost and the instance will be brought back to the initial state.

SL hangs during reboot, need to power-cycle

Hi,
I've upgraded my 10.5 machine to 10.6. Now my machine does not reboot anymore. It hangs on a blue screen with the spinning wheel. I have to turn my Mac off to get it back on.
Upgrading to 10.6.1 did not resolve this issue.
Before the upgrade to 10.6 the machine rebooted just fine.
Any ideas what might be wrong?
Thanks

If you have anything connected to your USB ports (or firewire ports) you might want to try and disconnect them and try booting again. My problem was a slow shut down with the little cartwheeling going like crazy for a while. You could guarantee that if you had the slow shut down then there was a problem booting the computer. Once I disconnected the two external drives everything works OK.

Computer was running fine until today, when upon trying to unlock it there was a hang. I could move the mouse cursor, and the keyboard LEDs would toggle, but there was nothing on the screen (except the cursor).
Throughout the day, I've seen random graphical corruption + hang.
Looking through the system logs, before each hang I see something like the following:

That line reading "GPU lockup" seems especially suspicious.
This is a fairly new graphics card; purchased in the last six months. I'm using nouveau, obviously, with stock kernel. Have never seen anything like this with this graphics card before today. Don't think I've done a system update yet this year.
Some Googling turned up a possible match (I had the URL, but then somehow it got dropped, oh well), but that's not identical since the problem described in the bug is the X server not starting, while mine will start and run for a few hours before barfing. It does involve the "GPU lockup" message, and is a software bug, but that bug is theoretically fixed as of the 3.6 kernel (I'm using 3.6.11).
I'm going to try installing the nvidia proprietary drivers, but that's a pain in my rear.
Does this problem sound familiar to anyone? Any upstream bug I could track?

[SOLVED] Clarify - directory ownership differs during sysmd upgrade

Hello,
I get the warning (see below) - and I am wondering if I understand it correctly that I do not need to do anything about this warning?
warning: directory ownership differs on /var/log/journal/remote/
filesystem: 0:998 package: 0:0
It is the same warning discussed in this thread: https://bbs.archlinux.org/viewtopic.php?id=193782, and since it is solved,
and the bug report here: https://bugs.archlinux.org/task/43852 also does not give me a conclusive answer, I opened this one.

Hello,
I tried to solve this by doing:
1. Checking the systemd package
pacman -Qkk systemd
warning: systemd: /var/log/journal/remote (GID mismatch)
2. Change the "/var/log/journal/remote" to the root group and user
# chown root:root /var/log/journal/remote/
3. Checking the systemd package again
pacman -Qkk systemd
systemd: 1003 total files, 0 altered files
4. Seems correct, so I rebuild my initramfs and reboot (hoping this will keep the above chown edit)
# mkinitcpio -p linux
# reboot
Checking the systemd package again
pacman -Qkk systemd
warning: systemd: /var/log/journal/remote (GID mismatch)
So after my reboot I am back where I started - and I do not get it, what am I suppose to to with this warning, point me in the right direction please.

From later in this thread:
Solution
Ok, do:
ck-list-sessions
There were two sessions for myself. So, the new slim is starting your exec line already with a console kit session. This is new behavior. It didn't before.
So, I modified my exec line to remove "ck-launch-session" in .xinitrc to:
exec dbus-launch --exit-with-session startxfce4
Reverted the changes I made to the shutdown/restart policy and rebooted. Shutdown, restart, mounting USB drive: they all work again now.
Edit: from even later on in this thread, just:
exec startxfce4
As your .xinitrc exec line should be sufficient for practically anyone. "startxfce4" does the dbus-launch itself.
Original post here:
Changed in my /etc/slim.conf:
default_path /bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin
Same issue, in Action buttons Shutdown and Restart grayed out.
in .xinitrc, launch line:
exec ck-launch-session startxfce4
Launch line was:
exec ck-launch-session dbus-launch --exit-with-session startxfce4
But, same issue with that launch line. Was googling and I found results saying dbus-launch is contained within startxfce4.

I have a report from WhatisHang which (in theory) tells my why my firefox constantly hangs up. But I need someone who can help figure this out.

I hope this section will work, i couldnt find a place for Hang ups, and this problem doesnt usually cause a full crash, which is why it was hard to figure it out.
I finally used the program WhatisHang to try to get an idea of what is causing the seemingly random hanging, but have been unable to find anyone who can help me with it.
I have posted the Troubleshooting Information, though i dont think it would be of much help.
I have the report available but dont know where i can post it.

I must admit I seem possibly to be suffering from hangs also, although as I am often not in a hurry when using firefox on this machine it has little impact. I am using a legacy computer and tend to blame this on the computer or maybe background tasks such as from security software or indexing.
'''Do you still get the hangs in safe mode with all''' (or maybe all but one essential plugin if you think a plugin is involved in the hangs) '''plugins disabled ?
Have you tried to rule out
* background tasks are the problem, (at least monitor what else is running using Task Manager or sysinternals process explorer)
* [[is my firefox problem a result of malware|malware]]. ( consider full system scans with multiple tools/software)
* any other interacting programs or plugins (some may not be listed in firefox, you may need to check / uninstall from the OS {Windows Control Panel})
**it may also be an idea to check hangs still occur when WhatIsHangs is not in use.
* have you tried logging the cc & gc times in the error console, (if for instance you see times in 1000s of milliseconds appearing you may have then identified one reason for firefox being unresponsive, even if the cause is not yet identified. - a symptom the memshrink firefox developers will no doubt be eager to investigate)
* if you can get hangs in safe mode, on at least the Aurora channel releases I suggest you immediately go ahead and file a bug yourself. (I will try to find time if not today then next weekend to look more closely at my own system to see if it is showing hangs in firefox use)
** ideally try with all default preferences
** As you have changed preferences, I suggest you include as a attachment in the bug your list of user modified preferences (use ''about:support'' or Troubleshooting Information option)
** State what security software is in use, it could be an important factor. (I imagine the majority of users have security software, or if not have security vulnerabilities and potentially an undetected malware problem)
I will try to find and download a copy of WhatIsHang, see if it works on my system and what results it then shows.
I realise I have not said anything terribly helpful I solving your problem, but I suspect you are not alone in having hangs, if you are able to spare the time to investigate and report I am sure it will help others.
Firefox has had a few problems recently that would have been solved sooner if they were investigated when first reported, but unfortunatly an advantage of firefox is how easy it is to customise, but the downside is differentiating between a firefox fault and customisation problems.

[SOLVED]Arch hangs on startup, unable to find root device Mac

For posterity, I'm editing the post with how I solved both issues.
Hi All,
I'm trying to dual boot Arch and Mac 10.4.11 on an old 32 bit MacbookPro1,1. I did the following:
1) Partitioned Drive with an EFI partition, Mac partition, root partition, home partition, and swap partition
2) Installed Mac to its respective partition
3) Installed rEFInd to the ESP
4) Confirmed the rEFInd was able to boot Mac
5) Installed Arch to the root partition and mounted the separate /home and swap partitions
6) Followed the beginners guide for the rest of the installation
7) Did NOT install a bootloader
- I am just using rEFInd to boot Arch; I installed Ubuntu in a similar fashion on my other (2013) MBP. I didn't create a mount point for /boot, did not install GRUB, and it works perfectly
8) Rebooted. Selected the Arch installation from the rEFInd menu, it launched, and shortly after I am presented with this message:
ERROR: device 'UUID=142bf...777' not found. Skipping fsck.
ERROR: Unable to find root device 'UUID=142bf...777'.
You are being dropped to a recovery shell
Type 'exit' to try and continue booting
sh: can't access tty: job control turned off
[rootfs /]#
I then booted to the live cd to try and do some noob detective work:
# mkdir /mnt/arch
# mount /dev/sda3 /mnt/arch
# cat /mnt/arch/etc/fstab
# cat /mnt/arch/etc/mkinitcpio.conf # my searching suggested the HOOKS might be the issue
HOOKS="base udev autodetect modconf block filestystems keyboard fsck"
Here is the output of /etc/fstab
I am including the outputs of
# lsblk
# fdisk -l /dev/sda
# blkid
as a photo.
EDIT:
I was able to use rEFInd's line editor to boot with the fallback image. Everything went well for the first five seconds and I got past the previously mentioned failure. However, it is now stuck at
[ OK ] Started Rebuild Hardware Database
I booted again, and it froze at:
[ OK ] Started udev Kernel Device Manager.
I did this a few more times and it froze at:
[ OK ] Reached Target Swap.
[ OK ] Reached Target Sound Card.
and
[ OK ] Started Flush Journal to Persistent Storage.
Why is it freezing at different points each time I boot (with fallback)?
EDIT 2 [HALF SOLVED]:
By switching the order of the hooks ( I still have no idea what they do) as per this link, I am now able to boot in normal (not fallback) mode. For the record, here is what I did:
# mkdir /mnt/arch
# mount /dev/sda3 /mnt/arch
# chroot /mnt/arch/ /bin/bash/
# nano /etc/mkinitcpio.conf # here I put block before autodetect in the hooks line (Why isn't this the default if it prevents the system from booting?)
# mount -t proc proc /proc
# mount -t sysfs sys /sys
# mount -t devtmpfs udev /dev
# mkinitcpio -p linux
I then rebooted and it started up, except now it is freezing at various points in the startup sequence like the fallback image did above. What could be causing this issue?
EDIT 3 [SOLVED]
I don't know why this worked, but after following this advice I am now able to boot into login. Steps:
1) Select Arch in the rEFInd menu and press F2
2) Press F2 again to edit the boot parameters
3) Scan to the end of the line and add
nomodeset
after the linux image.

Yes, the UUID displayed in the error message upon bootup is the same as the UUID for /dev/sda3 as found when running blkid which is the same as the UUID for the root partition in /etc/fstab.

[SOLVED] sshfs - Hangs at different occations (reboot needed?)
