  • Conky starts above windows in Ubuntu Maverick

    - by DesertIvy
    Hey guys, I did not run into this problem until I upgraded my Ubuntu box to Maverick Meerkat (10.10). Basically, whenever I start my computer, conky runs as expected, except it gets drawn over any windows that I load (see screenshot). To fix this for a single session, I simply restart conky by running killall conky; conky in a terminal. Conky gets re-drawn below active windows (namely, only appearing on my desktop), and does not have the border/drop-shadow, but I have to do this every time I start a new session. Is there a simple way to fix this? I have a small shell script that I run on startup, but it does not seem to solve the problem. #!/bin/bash sleep 10 && conky; sleep 5 && killall conky; conky; Below is the non-text part of my .conkyrc file. # Conky settings # background yes update_interval 1 cpu_avg_samples 2 net_avg_samples 2 override_utf8_locale yes double_buffer yes no_buffers yes text_buffer_size 2048 #imlib_cache_size 0 temperature_unit fahrenheit # Window specifications # own_window yes own_window_type override own_window_transparent yes own_window_hints undecorate,sticky,skip_taskbar,skip_pager,below border_inner_margin 0 border_outer_margin 0 minimum_size 200 250 maximum_width 200 alignment tr gap_x 220 gap_y 280 # Graphics settings # draw_shades no draw_outline no draw_borders no draw_graph_borders no # Text settings # use_xft yes xftfont caviar dreams:size=8 xftalpha 0.5 uppercase no temperature_unit celsius default_color FFFFFF # Lua Load # lua_load ~/.lua/scripts/clock_rings.lua lua_draw_hook_pre clock_rings

  • samba "username map" stopped to work

    - by Kris_R
    It was time to upgrade our group server (new HDs, problems with old installation of DRBD, etc..). Going as usually for CentOS i upgraded whole system from 6.3 to 6.4 The later one came with samba 3.6 as the old one was 3.5. I transferred most of users by copying /etc/password, /etc/shadow and samba accounts with pdbedit. Homes were on nfs-drive. The translation of unix accounts to samba accounts are located in /etc/samba/smbusers. Strangely enough on some windows clients there was problem to connect to samba-shares. In one case the only thing that worked was, instead of giving windows name, to use the unix account. In another one, it was possible to mount network drive and to open it in Windows Explorer, however other applications like "Total commander" at the attempt of opening this drive gave the message "Cannot connect to z:" (sometimes at this moment user/pass were requested). The smb.conf has following entries: [global] security = user passdb backend = tdbsam username map = /etc/samba/smbusers ... [Kris] comment = Kris's Private path = /SMB/Users/Kris writeable = yes read only = no browseable = yes users = krisr printable = no security mask = 0777 force security mode = 0 directory security mask = 0777 force directory security mode = 0 force create mode = 0775 force directory mode = 6775 The smbusers: # Unix_name = SMB_name1 SMB_name2 ... krisr = Kris Of course testparm runs without any errors. I was used from samba 3.5 to outputs of form Mapped user Kris to krisr. Nothing like this happens now. Just message check_sam_security: Couldn't find user Kris in passdb. I read on web that some guys had problem with 3.6 and security = ADS, but these were not helpful for me. I'm seriously thinking about downgrading back to samba 3.5 but before this step I wanted to ask if somebody knows the solution of these problems. p.s. i've asked this question at serverfault but no answer came. Maybe I have more luck with this forum. Sorry for duplicate if any of you reads both.

  • Failed to su after making a chroot jail

    - by arepo21
    On a 64 bit CentOS host I am using script make_chroot_jail.sh to put a user in a jail, not permitting it to see anything expect it's home at /home/jail/home/user1. I did it typing this: sudo ./make_chroot_jail.sh user1 after, when trying to connect to user1 first i was getting an error like: /bin/su: user guest does not exist i have fixed this by copying some missed libraries: sudo cp /lib64/libnss_compat.so.2 /lib64/libnss_files.so.2 /lib64/libnss_dns.so.2 /lib64/libxcrypt.so.2 /home/jail/lib64/ sudo cp -r /lib64/security/ /home/jail/lib64/ But now, when trying to connect to user1 typing su user1 and then typing it's password, i am getting this error: could not open session So the question is how to connect to user1 in this situation? P.S. Here are the permissions of some files, this might be helpful in order to provide a solution: -rwsr-xr-x 1 root root /home/jail/bin/su drwxr-xr-x 4 root root /home/jail/etc -rw-r--r-- 1 root root /home/jail/etc/pam.d/su -rw-r--r-- 1 root root /home/jail/etc/passwd -rw------- 1 root root /home/jail/etc/shadow UPDATE1 After some modifications i managed to connect to user1, but the session closes immediately! I guess this a PAM issue, however cant find a way to fix it. Here the log entry for close action from /val/log/secure: Oct 6 15:19:42 localhost su: pam_unix(su:session): session closed for user user1 What makes the session to exit immediately after launching?

  • How can I run Gnome or KDE locally in Cygwin?

    - by John Peter Thompson Garcés
    Apparently it is possible to do this using cygwin ports, as can be seen in screenshots. I followed this how-to to get apt-cygports set up, and I used it to install gnome-session. This how-to supposedly gives the commands needed to run Gnome or KDE, but whenever I try to run Gnome, a blank X-window pops up and then quickly disappears. Here is the terminal output: $ startx /usr/bin/dbus-launch gnome-session xauth: file /home/jpthomps/.serverauth.4168 does not exist Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 1.10.3.0 OS: Windows 7 Service Pack 1 [Windows NT 6.1 build 7601] (WoW64) Package: version 1.10.3-12 built 2011-08-22 XWin was started with the following command line: /usr/bin/X :0 -auth /home/jpthomps/.serverauth.4168 (II) xorg.conf is not supported (II) See http://x.cygwin.com/docs/faq/cygwin-x-faq.html for more information LoadPreferences: /home/jpthomps/.XWinrc not found LoadPreferences: Loading /etc/X11/system.XWinrc LoadPreferences: Done parsing the configuration file... winDetectSupportedEngines - DirectDraw installed, allowing ShadowDD winDetectSupportedEngines - Windows NT, allowing PrimaryDD winDetectSupportedEngines - DirectDraw4 installed, allowing ShadowDDNL winDetectSupportedEngines - Returning, supported engines 0000001f winSetEngine - Using Shadow DirectDraw NonLocking winScreenInit - Using Windows display depth of 32 bits per pixel winFinishScreenInitFB - Masks: 00ff0000 0000ff00 000000ff Screen 0 added at virtual desktop coordinate (0,0).

  • Users database empty after Samba3 to Samba4 migration on different servers

    - by ouzmoutous
    I have to migrate a Samba 3 to a new Samba 4 server. My problem is that the database on the samba 3 server seems a bit empty. The secrets.dtb file is only 20K whereas the “pbedit -L |wc -l”command give me 16970 lines. On my Samba3 /var/lib/samba is 1,5M After I had migrate the databse (following instructions on http://dev.tranquil.it/index.php/SAMBA_-_Migration_Samba3_Samba4), “pdbedit -L” command on the new server give me only : SAMBA4$, Administrator, dns-samba4, krbtgt and nobody. So I tried to create a VM with a Samba3. I added some users, done the same things I did for the migration and now I can see the users created on the VM. It’s like users on the Samba 3 server are in a sort of cache. I already migrate the /etc/{passwd,shadow,group} files and I can see users with the “getent passwd” command. Any ideas why my users are present when I use pdbedit but the database is so empty ?

  • Setup git repository on gentoo server using gitosis & ssh

    - by ikso
    I installed git and gitosis as described here in this guide Here are the steps I took: Server: Gentoo Client: MAC OS X 1) git install emerge dev-util/git 2) gitosis install cd ~/src git clone git://eagain.net/gitosis.git cd gitosis python setup.py install 3) added git user adduser --system --shell /bin/sh --comment 'git version control' --no-user-group --home-dir /home/git git In /etc/shadow now: git:!:14665:::::: 4) On local computer (Mac OS X) (local login is ipx, server login is expert) ssh-keygen -t dsa got 2 files: ~/.ssh/id_dsa.pub ~/.ssh/id_dsa 5) Copied id_dsa.pub onto server ~/.ssh/id_dsa.pub Added content from file ~/.ssh/id_dsa.pub into file ~/.ssh/authorized_keys cp ~/.ssh/id_dsa.pub /tmp/id_dsa.pub sudo -H -u git gitosis-init < /tmp/id_rsa.pub sudo chmod 755 /home/git/repositories/gitosis-admin.git/hooks/post-update 6) Added 2 params to /etc/ssh/sshd_config RSAAuthentication yes PubkeyAuthentication yes Full sshd_config: Protocol 2 RSAAuthentication yes PubkeyAuthentication yes PasswordAuthentication no UsePAM yes PrintMotd no PrintLastLog no Subsystem sftp /usr/lib64/misc/sftp-server 7) Local settings in file ~/.ssh/config: Host myserver.com.ua User expert Port 22 IdentityFile ~/.ssh/id_dsa 8) Tested: ssh [email protected] Done! 9) Next step. There I have problem git clone [email protected]:gitosis-admin.git cd gitosis-admin SSH asked password for user git. Why ssh should allow me to login as user git? The git user doesn't have a password. The ssh key I created is for the user expert. How this should work? Do I have to add some params to sshd_config?

  • Unison synchronization problem. Roots are not identical after synchronization.

    - by binary255
    Hi. When I synchronize two folders using Unison, only one of the roots seems to be affected. Below are all the information I would think is necessary to figure out why it is working like it is. I'm using $ unison -version unison version 2.27.57 From the Ubuntu repositories. My work laptop: $ echo $UNISONLOCALHOSTNAME worklaptop $ pwd /home/userfoo $ ls -lAR .unison* .unison: total 8 drwxr-xr-x 2 userfoo userfoo 4096 2010-04-26 11:39 backups -rw-r--r-- 1 userfoo userfoo 231 2010-04-26 11:38 default.prf .unison/backups: total 0 .unisonroot: total 0 $ cat .unison/default.prf # Roots of the synchronization root = /home/userfoo/.unisonroot root = ssh://devel//home/userbar/.unisonroot path = * backuplocation = central backupdir = /home/.unison/backups backupprefix = $VERSION.bak $ mkdir .unisonroot/aDirectoryFrom-$UNISONLOCALHOSTNAME $ echo something >.unisonroot/aFileFrom-$UNISONLOCALHOSTNAME $ ls .unisonroot/ aDirectoryFrom-worklaptop aFileFrom-worklaptop And the Ubuntu server I want to synchronize with: $ echo $UNISONLOCALHOSTNAME workcmpuserbardevel $ pwd /home/userbar $ ls -lAR .unison* .unison: total 4 drwxr-xr-x 2 userbar userbar 4096 2010-04-26 11:38 .unison .unison/.unison: total 0 .unisonroot: total 0 $ mkdir .unisonroot/aDirectoryFrom-$UNISONLOCALHOSTNAME $ echo something >.unisonroot/aFileFrom-$UNISONLOCALHOSTNAME $ ls .unisonroot/ aDirectoryFrom-workcmpuserbardevel aFileFrom-workcmpuserbardevel I perform the unison synchronization: $ echo $UNISONLOCALHOSTNAME worklaptop $ unison Contacting server... Connected [//worklaptop//home/userfoo/.unisonroot -> //workcmpuserbardevel//home/userbar/.unisonroot] Looking for changes Warning: No archive files were found for these roots, whose canonical names are: /home/userfoo/.unisonroot //workcmpuserbardevel//home/userbar/.unisonroot This can happen either because this is the first time you have synchronized these roots, or because you have upgraded Unison to a new version with a different archive format. Update detection may take a while on this run if the replicas are large. Unison will assume that the 'last synchronized state' of both replicas was completely empty. This means that any files that are different will be reported as conflicts, and any files that exist only on one replica will be judged as new and propagated to the other replica. If the two replicas are identical, then no changes will be reported. If you see this message repeatedly, it may be because one of your machines is getting its address from DHCP, which is causing its host name to change between synchronizations. See the documentation for the UNISONLOCALHOSTNAME environment variable for advice on how to correct this. Donations to the Unison project are gratefully accepted: http://www.cis.upenn.edu/~bcpierce/unison Press return to continue.[<spc>] Waiting for changes from server Reconciling changes local workcmps... dir ----> aDirectoryFrom-worklaptop [f] file ----> aFileFrom-worklaptop [f] Proceed with propagating updates?

The desired result would have been that the two folders would have ended up being identical, holding the union of the contents of the two roots.

  • PostgreSQL user authentication against PAM

    - by elmuerte
    I am trying to set up authentication via PAM for PostgreSQL 9.3. I already managed to get this working on an Ubuntu 12.04 server, but I am unable to get this working on a Centos-6 install. The relevant pg_hba.conf line: host all all 0.0.0.0/0 pam pamservice=postgresql93 The pam.d/postgressql93 is the default config shipped with the official postgresql 9.3 package: #%PAM-1.0 auth include password-auth account include password-auth When a user tries to authenticate the following is reported in secure log: hostname unix_chkpwd[31807]: check pass; user unknown hostname unix_chkpwd[31808]: check pass; user unknown hostname unix_chkpwd[31808]: password check failed for user (myuser) hostname postgres 10.1.0.1(61459) authentication: pam_unix(postgresql93:auth): authentication failure; logname= uid=26 euid=26 tty= ruser= rhost= user=myuser The relevant content of password-auth config is: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so The problem is with the pam_unix.so. It is unable to validate the password, and unable to retrieve the user info (when I remove the auth entry of pam_unix.so). The Centos-6 install is only 5 days old, so it does not have a lot of baggage. The unix_chkpwd is suid and has execute rights for everybody, so it should be able to check the shadow file (which has no privileges at all?).

  • FastGate A20 Line And Himem.sys Issue With Updating BIOS

    - by Boris_yo
    I have been persistent with a thought to perform my first BIOS update ever through MS-DOS but have been postponing this task until today. Despite people telling me any bootable ISO will do it either through CD-ROM or RAMDRIVE, I am still having problems. First is the problem with CD-ROM driver trying to make it work with 4 driver files (cd1.SYS, cd2.SYS, cd3.SYS, cd4.SYS) as well as starting RAMDISK proved to be failure: CD-ROM XMS Allocation Error RAMDISK XMS Allocaton Error (X: and R: drives not working) This A20 line seemed to be the obstacle which then after a couple of searches pointed me to this article on Microsoft website. It seems that FastGate is the culprit which takes over A20 line and conflicts with himem.sys which should be handling it causing the driver to be unable to allocate memory resources. Albeit article suggests 2 workarounds which is disabling FastGate option or adding switch, I read that the former workaround could cause problems which involves later tinkering BIOS, disabling shadow copy etc. while the latter workaround can just hang system as stated in the link above. I assume it just hangs the boot process from image file though. Summing up the above, I am cautious and think it is risky to follow both workarounds because disabling FastGate or trying adding switch by trying available switches from 1-14 or 16, could crash the BIOS update process by itself. I could do this without the need for himem.sys with bootable USB thumbdrive by making it to be seen as USB-HDD, but some time ago I read that it is never a good idea to update BIOS from hard drive so even thought it is simulation, who knows... Maybe it will deactivate hard drive in the middle of the BIOS update process or even USB thumbdrive per se? One forum discussion was about updating BIOS and somebody suggested to not load himem.sys for some reason, but now that I think of it, what if BIOS update needs upper memory?

  • Controller Error: Do I need to worry?

    I have a HP Pavillion dv5224ea Laptop with Windows 7 on it. Recently I discovered a Error in Event Viewer: The driver detected a controller error on \Device\Ide\IdePort1.

What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

  • Samba4/Ubuntu Shares Incorrectly Available to All Users

    - by Dan
    I've got my Ubuntu server working with Samba4 and got it set up as the Primary domain controller on my network with AD and all that goodness. However, I'm trying to get my Samba configuration to work with the users and groups I've defined with the Active Directory tools from Windows. For instance, I've got a share X which I want users A and B (as part of the 'management' group, known as LLGrpManager in my setup) to see, but no body else. However, after making changes to the configuration, restarting Samba, I test by connecting to the share with my Mac over Samba as user 'C' which isn't part of the management group, and I can, incorrectly, see the X share. I've tried alsorts of combinations of specifying the group with no luck at all. I've got a feeling that my global config might be too lenient or something to do with file permissions but being a bit green, I'm without clue. My /etc/samba/smb.conf # Global parameters [global] server role = domain controller server string = Office Server workgroup = LLDOMAIN realm = lldomain.local netbios name = DUMBO passdb backend = samba4 logon path = \\%L\profiles\%U logon drive = L: log file = /var/log/samba/%m.log max log size = 50 security = ads domain logons = yes domain master = auto usershare allow guests = no valid users = %S [netlogon] path = /var/lib/samba/sysvol/lldomain.local/scripts read only = no guest ok = no [sysvol] path = /var/lib/samba/sysvol read only = No guest ok = no valid users = @LLDOMAIN\LLGrpManager [ShareX] path = /data comment = Entire Data Volume guest ok = no comment = Entire Data Volume guest ok = no valid users = @LLDOMAIN\LLGrpManager admin users = @LLDOMAIN\LLGrpManager browsable = no inherit acls = yes inherit permissions = yes ...

  • Comprehensive solution for managing patches, event viewing, change management, inventory, etc

    - by Holocryptic
    I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

  • How to cache authentication in Linux using PAM/Kerberos authentication (for CVS)?

    - by Calonthar
    We have several Linux servers that authenticate Linux user passwords on our Windows Active Directory Server using PAM and Kerberos 5. The Linux distro we use is CentOS 6. On one system, we have several Version Control Systems like CVS and Subversion, both of which authenticate users throug PAM, such that users can use their normal Unix resp. Windows AD accounts. Since we started using Kerberos for password authentication, we experienced that CVS on a client machine is often much slower in establishing a connection. CVS authenticates the user on every request (eg. cvs diff, log, update...). Is is possible to cache the credentials that kerberos uses, sucht that is does not need to ask the Windows AD server every time a user executes a cvs action? Our PAM config /etc/pam.d/system-auth looks like the following: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth sufficient pam_krb5.so use_first_pass auth required pam_deny.so account required pam_unix.so broken_shadow account sufficient pam_succeed_if.so uid < 500 quiet account [default=bad success=ok user_unknown=ignore] pam_krb5.so account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password sufficient pam_krb5.so use_authtok password required pam_deny.so session optional pam_keyinit.so revoke session required pam_limits.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so session optional pam_krb5.so

  • "could not find suitable fingerprints matched to available hardware" error

    - by Alex
    I have a thinkpad t61 with a UPEK fingerprint reader. I'm running ubuntu 9.10, with fprint installed. Everything works fine (I am able to swipe my fingerprint to authenticate any permission dialogues or "sudo" prompts successfully) except for actually logging onto my laptop when I boot up or end my session. I receive an error below the gnome login that says "Could not locate any suitable fingerprints matched to available hardware." What is causing this? here are the contents of /etc/pam.d/common-auth file # # /etc/pam.d/common-auth - authentication settings common to all services # # This file is included from other service-specific PAM config files, # and should contain a list of the authentication modules that define # the central authentication scheme for use on the system # (e.g., /etc/shadow, LDAP, Kerberos, etc.).

  • pam_tally2 causing unwanted lockouts with SCOM or Nervecenter

  • How can I create a simple Exchange 2010 backup solution?

    - by bduncanj
    I'm sure this question's been asked a dozen times in one form or another, however after much searching, there doesn't appear to be an obvious simple recovery solution for a single Exchange box. We're using Exchange 2010 on a single server, the server hosts the AD and nothing else on the network uses the AD. The intent is to run this server as you would an externally hosted Exchange server - access only via HTTP (RPC mode or OWA) - all other ports blocked. I've a daily backup running, using Windows Server 2008 volume shadow service to backup the Exchange data to an external hard disk. My question is, how do I perform a bare metal recovery of this server? 1) Do I need to be explicitly including the active directory information in this nightly backup, or will it be there by virtue of the fact that this system is the primary AD server and the Windows backup service knows this? 2) I understand I can re-install Server 2008 onto my new hardware (in the case of hardware failure) and then run Exchange 2010 setup.exe with a /recover argument, referencing the backup volume. 3) It is acceptable to have some downtime during this recovery process. But is there anything else I should be aware of? Thanks! Duncan

  • What could cause Windows 7 to hang whenever I install something?

    - by Larsenal
    I've had this problem when installing several different programs (iTunes, Adobe Acrobat Reader just to name two). Regardless of what the program is, the install usually gets at least 90% through the process and then just hangs. I don't see anything bad in the event log besides the following (and this didn't occur exactly at the time of install): wuaueng.dll (964) SUS20ClientDataStore: A request to write to the file "C:\Windows\SoftwareDistribution\DataStore\DataStore.edb" at offset 16252928 (0x0000000000f80000) for 32768 (0x00008000) bytes succeeded, but took an abnormally long time (185 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. I've run check disk and it passed. I've had some problems with BIOS settings in the past with Windows 7, but I'm not sure whether that could be related. Update... I also see this error in the event log: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process. Operation: Gathering Writer Data Context: Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220} Writer Name: System Writer Writer Instance ID: {33493f01-ac1b-4efb-a378-3053ab03100d} One last wrinkle.... I see "Previous versions" of c:\ which look like they correspond to the time of attempted installation.

  • Hosed Windows 7 permissons

    - by Anthony
    Here is the most interesting thing I've noticed since the problems started: If I go into a control panel/system module (in this case the Resource Monitor) that has a "Check Online" type option, Firefox (my default browser) opens right up without a problem. But if I just start Firefox from any shortcuts (start menu, desktop, etc), the Firefox process starts up (and the start menu icon starts glowing) only to end without notice a few seconds later. Possibly related: If I start up in Safe-Mode (w/o Networking, but haven't tried with yet), I can start up FF or Chrome just fine, but if I attempt to open Chrome normally, I get a permissions error. Opera and Safari seem to be okay (mostly). Safari crashes when I try to download any files. All of the above leads me to believe that some (but clearly not all) core files have messed up permissions. Or rather, that I no longer have permission. System still does, based on Firefox opening without fail when the system initiates it. I've run MS Forefront once in normal mode, Malwarebytes twice in normal mode and once in safe-mode. One trojan found and deleted, but the problem persists. Two other things worth mentioning: I accidentally duplicated my library... I thought I'd try to add the "Internet" folder to my start menu, next to music and downloads. The first advanced thing I tried was "create new library". I clearly misunderstood what this means. I thought it was a way to add virtual folders to the library (which I thought, in turn, would allow me to choose it as a link on the start menu), but instead it recreated my already existing user folder, AppData and all. I didn't notice this until today. Then I tried setting permissions for my User folder to full control, recursively... Confused but not giving up,I thought I could maybe create a shortcut to the NetHood folder manually, but instead got hit with an access denied error. So I tried to change the permission levels for all sub-folders to my user folder so that I had full control. I got several access denied errors along the way. At this point I gave up, went out, ended up caught in the rain and stuck on a friend's couch and showing up late for work the next day. Thanks for nothing, Microsoft. When I finally got home today (20 hours later), I noticed that Firefox was acting really strange. I tried opening Chrome to see if the problem was client side or server side, and instead got the above-mentioned "you don't have permission to open this program" alert. And I think that's the whole story. Oh, I also did a system restore, but not chose a point from this morning (an auto update), and it worked but the problem wasn't fixed. And then all the earlier restore points were gone. So the questions are: a) is there a way to set the admin and user privs back to "default"? b) would this, in anyone's expert opinion, fix the problems I'm having? c) how come being logged in as an admin isn't the same as being logged in with admin privs? It seems that half the time I have to do run as admin for fairy standard things because i'm being treated as me-theuser and not me-theadmin. Thanks for reading.

  • Application that will identify percentage of your system disk bandwidth used on a user-application by user-application basis?

    - by Warren P
    I always (subjectively) feel my computer is far too slow (however fast it is), and so I'm always looking for ways to measure and understand what my computer is actually doing, that is making it seem "slow" to me. It has been my observation that my software-developer workload is most often disk-bound (I am waiting for Disk I/O) more than CPU bound. What has made it worse, is that I am using a corporate PC that has in-memory active-scanning anti-virus software that I do not have control over, and also some IT department mandated services that seem to suck up a lot of available hard-disk bandwidth. The best tool I have seen (in Windows 7) is the Resource Monitor which I usually acess from the button in the task Manager. The disk IO page, however, seems to label Disk Activity at a very low level (for example, showing the Volume Shadow Storage, which is flushing information obviously written by something ELSE other than VSS itself, and then writes to Pagefile.sys, which are obviously due to Virtual Memory faults in some application). What I would like to know is if a utility exists that can add up all direct disk input and output by user-level process, or find the process or service that caused VM or VSS activity. In that way, I hope, you could establish a real idea of how much of your computer's precious disk subsystem bandwidth is attributable to a particular application. here's a scenario: MyApp.exe writes 100k/s and reads 100k/s directly. VSS ends up writing another 100k/s. pagefaults caused inside MyApp.exe cause another 100k/s of writes. So the total "cost" of MyApp.exe running, during a period of time (let's say 1 second) is 400k/s, whereas you can only directly observe half of that, in Resource Monitor. Is there a smarter disk-IO watching piece of software I can use?
