  • Cannot change permissions in symlinked dropbox directory in Ubuntu 10.10

    - by Reactor5
    Title pretty much says it all, but here's what I'm doing... ls -l produces this... drwx------ 1 brian brian 4096 2010-12-28 14:19 foldername -rw------- 1 brian brian 0 2010-12-28 15:54 index.html after typing something like chmod o=rx index.html the output of ls -l is the same. This happens whether or not I'm in the original location or the symlink location. However, as a further twist, the output of chmod -v o=rx index.html is the following: mode of `index.html' changed to 0605 (rw----r-x) The location is also being symlinked to by apache. What's going on with my permissions?

  • USB Hardware vs. Software Write Lock

    - by TreyK
    I'm in the market for a USB flash drive, and remember this cool feature a tiny 32MB flash drive of mine had: a write lock switch. This seemed like it would be an amazing feature to have as a shield against any nastiness happening to the drive on an unfamiliar computer. However, very few drives on the market offer this feature. Instead, it seems that forms of software protection are the more prominent method. This software protection causes me a bit of uneasiness, as it seems like this software wouldn't be nearly as bulletproof as a physical switch. Also, levels of protection seem to vary from product to product. Being able to protect certain folders from reading and/or writing would be nice, but is the security trade-off worth it? Just how effective can this software protection be? Wouldn't a simple format be able to clean any drive with software protection? My drive must also be compatible with Windows XP, Vista, and 7, as well as Linux and Mac. What would be the best way forward for getting a well-sized (~8GB) flash drive with a strong write protection implementation, for little or no more than a regular drive? Thanks.

  • Networked Parallel Port in Linux / KVM / QEMU

    - by korkman
    What I want to use is the "-parallel" tcp or udp option from KVM / QEMU, but I don't seem to find any server for this client. I don't serve a printer but a hardware dongle. I checked ser2net, which does provide "/dev/lp0" sharing, but it doesn't seem to work for KVM / QEMU. I suspect KVM / QEMU requires "/dev/parport0". I did rmmod lp, modprobe ppdev, linked ser2net to parport0, but it didn't work out. Perhaps ser2net is not suited for this. I tried socat as well, and I tried netcat. No success. Does anyone know any KVM / QEMU compatible parallel port server? Or did any of netcat, socat or ser2net work for you?

  • Modem doesn't seem to pass internet connection to router

    - by Vian Esterhuizen
    I was supplied a Cisco DPC3825 modem by my ISP and use a Cisco E4200 as my main router. Today the Internet just stopped working, just out of the blue, I can't think of anything that would have triggered it. It's been working pretty good for the past month except for a few random blips here and there. After some trouble shooting I realized that a direct wired connection to the modem would get me Internet access but if I was wired to the router as I was before I would have no connection. Assuming it was router I connected a TP-Link WR841N but it had the exact same problem. Also, connecting to the router via Wi-Fi from multiple devices will connect me to the router but I still can't get access to the Internet. From these test, it seems that the modem just won't send Internet through to the router but is clearly connecting and able to directly connect to my PC. What I've Tried A full reset and factory reset on the E4200 A full reset on the modem (but I believe my ISP has remote access to the modem because the passwords and so on are always set back). My ISP has remotely reconfigured the modem What I Should Try What else can I try? What should I do to try to narrow down the issue? Can you figure out what the problem might be based on this information?

  • Windows XP ad-hoc networking

    - by Abhinav
    I have been using a Windows XP ad-hoc wireless network to connect my Macbook to the internet. Everything was working fine until after a restart of the XP machine, the network stopped appearing in the "Choose a wireless network" screen. It does not show up as an available network on the Macbook as well. But when I try to create a new network it shows me the network name. Creating a new network does not work either.

  • Is it reasonable to have multiple SSH keys?

    - by Leonid Shevtsov
    So far I've created a separate SSH key for each server I need to login to (for each purpose, to be more accurate). I did it out of a sense of security, just like different passwords to different sites. Does having multiple SSH keys actually improve security? All of them are used from the same machine, are located in the same ~/.ssh, most even have the same passphrase. So... should I give up the whole system and just use one SSH key for everything?

  • Poor home office network performance and cannot figure out where the issue is

    - by Jeff Willener
    This is the most bizarre issue. I have worked with small to mid size networks for quite a long time and can say I'm comfortable connecting hardware. Where you will start to lose me is with managed switches and firewalls. To start, let me describe my network (sigh, shouldn't but I MUST solve this). 1) Comcast Cable Internet 2) Motorola SURFboard eXtreme Cable Modem. a) Model: SB6120 b) DOCSIS 3.0 and 2.0 support c) IPv4 and IPv6 support 3-A) Cisco Small Business RV220W Wireless N Firewall a) Latest firmware b) Model: RV220W-A-K9-NA c) WAN Port to Modem (2) d) vlan 1: work e) vlan 2: everything else. 3-B) D-Link DIR-615 Draft 802.11 N Wireless Router a) Latest firmware b) WAN Port to Modem (2) 4) Servers connected directly to firewall a) If firewall 3-A, then vlan 1 b) CAT5e patch cables c) Dell PowerEdge 1400SC w/ 10/100 integrated NIC (Domain Controller, DNS, former DHCP) d) Dell PowerEdge 400SC w/ 10/100/1000 integrated NIC (VMWare Server) 4) Linksys EZXS88W unmanaged Workgroup 10/100 Switch a) If firewall 3-A, then vlan 2 b) 25' CAT5e patch cable to firewall (3-A or 3-B) c) Connects xBox 360, Blu-Ray player, PC at TV 5) Office equipment connected directly to firewall a) If firewall 3-A, then vlan 1 b) ~80' CAT6 or CAT5e patch cable to firewall (3-A or 3-B) c) Connects 1) Dell Latitude laptop 10/100/1000 2) Dell Inspiron laptop 10/100 3) Dell Workstation 10/100/1000 (Pristine host, VMWare Workstation 7.x with many bridged VM's) 4) Brother Laser Printer 10/100 5) Epson All-In-One Workforce 310 10/100 5-A) NetGear FS116 unmanaged 10/100 switch a) I've had this switch for a long time and never had issues. 5-B) NetGear GS108 unmanaged 10/100/1000 switch a) Bought new for this issue and returned. 5-C) Linksys SE2500 unmanaged 10/100/1000 switch a) Bought new for this issue and returned. 5-D) TP-Link TL-SG10008D unmanaged 10/100/1000 a) Bought new for this issue and still have. 6) VLan 1 Wireless Connections (on same subnet if 3-B) a) Any of those at 5c b) HP Laptop 7) VLan 2 Wireless Connection (on same subnet if 3-B) a) IPad, IPod b) Compaq Laptop c) Epson Wireless Printer Shew, without hosting a diagram I hope that paints a good picture. The Issue The breakdown here is at item 5. No matter what I do I cannot have a switch at 5 and have to run everything wireless regardless of router. Issues related to using a switch (point 5 above) SpeedTest is good. Poor throughput to other devices if can communicate at all. Usually cannot ping other devices even on the same switch although, when able, ping times are good. Eventual lose of connectivity and can "sometimes" be restored by unplugging everything for several days, not minutes or hours but we're talking a week if at all. Directly connect to computer gives good internet connection however throughput to other devices connected to firewall is at best horrible. Yet printing doesn't seem to be an issue as long as they are connected via wireless. I have to force the RV220W to 1000Mb on the respective port if using a Gig Switch Issues related to using wireless in place of a switch (point 5 above) Poor throughput to other devices if can communicate. SpeedTest is good. Bottom line Internet speeds are awesome. By the way, Comcast went WAY above and beyond to make sure it was not them. They rewired EVERYTHING which did solve internet drops. Computer to computer connections are garbage Cannot get switch at 5 to work, yet other at 4 has never had an issue. Direct connection, bypass switch, is good for DHCP and internet. DNS must be on server, not firewall. Cisco insists its my switches but as you can see I have used four and two different cables with the same result. My gut feeling is something is happening with routing. But I'm not smart enough to know that answer. I run a lot of VM's at 5-c-3, could that cause it? What's different compared to my previous house is I have introduced Gigabit hardware (firewall/switches/computers). Some of my computers might have IPv6 turned on if I haven't turned it off already. I'm truly at a loss and hope anyone has some crazy idea how to solve this. Bottom line, I need a switch in my office behind the firewall. I've changed everything. The real crux is I will find a working solution and, again, after days it will stop working. So this means I cannot isolate if its a computer since I have to use them. Oh and a solution is not throwing more money at this. I'm well into $1k already. Yah, lame.

  • Can I set up a separate RAID 5 devices?

    - by GregH
    I have a GIGABYTE GA-P55M-UD2 motherboard in my system (Windows 7 64 bit) and currently have a Western Digital SATA 10k RPM drive in it. Is it possible to add three more SATA drives to make a single RAID 5 device that is separate from the current 10k rpm drive that I have in it? Once I enable RAID for the SATA drives, I am not required to make all of the drives part of the RAID volume am I? I can have separate RAID'ed and non-RAID'ed volumes can't I?

  • Canon MF3200 Printer Problems

    - by Derick K.
    I bought a Canon MF3200 and used it on an old Windows laptop. The laptop broke, and now I'm trying to setup the printer on a laptop with Windows 7. I downloaded the new driver, and Windows was able to install it and mark it "Ready to Go." But whenever I try to print, an error comes up and it doesn't print. I tried to troubleshoot, to no avail. What else can I do? Any ideas on what the error might be?

  • How are PID's generated?

    - by Helltone
    On *nix, PIDs are unique identifiers for running processes. How are PID's generated? Is it just an integer which gets incremented or a more complex structure such as a list? How do they get recycled? By recycling I mean that, when a process terminates, it's PID will eventually be reused by another process.

  • Move database from SQL Server 2012 to 2008

    - by Rich
    I have a database on a SQL Sever 2012 instance which I would like to copy to a 2008 server. The 2008 server cannot restore backups created by a 2012 server (I have tried). I cannot find any options in 2012 to create a 2008 compatible backup. Am I missing something? Is there an easy way to export the schema and data to a version-agnostic format which I can then import into 2008? The database does not use any 2012 specific features. It contains tables, data and stored procedures. Here is what I have tried so far: I tried "tasks" - "generate scripts" on the 2012 server, and I was able to generate the schema (including stored procedures) as a sql script. This didn't include any of the data, though. After creating that schema on my 2008 machine, I was able to open the "Export Data" wizard on the 2012 machine, and after configuring the 2012 as source machine and the 2008 as target machine, I was presented with a list of tables which I could copy. I selected all my tables (300+), and clicked through the wizard. Unfortunately it spends ages generating its scripts, then fails with errors like "Failure inserting into the read-only column 'FOO_ID'". I also tried the "Copy Database Wizard", which claimed to be able to copy "from 2000 or later to 2005 or later". It has two modes: 1) "detach and attach", which failed with error: Message: Index was outside the bounds of the array. StackTrace: at Microsoft.SqlServer.Management.Smo.PropertyBag.SetValue(Int32 index, Object value) ... at Microsoft.SqlServer.Management.Smo.DataFile.get_FileName() 2) SQL Management Object Method which failed with error "Cannot read property IsFileStream.This property is not available on SQL Server 7.0."

  • Outlook 2007 OST File Indexing and OneNote 2007 Indexing are Broken

    - by Matt
    I'm running Outlook 2007 under Windows 7 Home Premium RTM. My OST file was previously being properly indexed but eventually searches significantly slowed down so I suspected a problem. Searching and indexing appears broken in OneNote 2007 as well as search time is now significantly longer. I brought up the Outlook 2007 Search Options dialog and noticed that my mailbox (running from an Exchange 2007 server) wasn't listed in the "Index messages in these data files:" list box. Next I ran the Windows "Find and fix problem with windows search" wizard which reported no errors. Then I brought up the Windows Indexing Options dialog which shows Outlook listed (as shown here): then clicked Advanced and Rebuilt the index. No dice - the listbox in the Outlook 2007 dialog still didn't show my mailbox. When I clicked the Modify button in the Indexing Options dialog I see the following: When I hover over the "oneindex://..." entry, the alt text indicates "This location is currently unavailable". When I delete it and rebuild the index, this entry returns. UPDATE: Comparison of the last screenshot above with a working PC shows that on the broken PC, the lower half of the dialog lists Outlook but neither Outlook or OneNote are showing in the upper half. The working PC has Outlook and OneNote in both parts of the dialog.

  • How to remotely open gedit with SFTP URL in Gnome through SSH?

    - by Álvaro Justen
    My setup is weird and I can't change it now. I have two machines: local-machine: it's my desktop running Ubuntu with Gnome remote-machine: it's one virtual machine, also running Ubuntu but without X In both machines I have my private and public SSH keys. I need to run SSH from remote-machine to local-machine and run gedit (in local-machine, under the default $DISPLAY) but openning a file in remote-machine throught SFTP. Something like this: myuser@remote-machine:~$ ssh local-machine "DISPLAY=:0.0 gedit sftp://remote-machine/some/file" The command above doesn't work. gedit shows this message: Could not open the file sftp://remote-machine/some/file. gedit cannot handle sftp: locations. Note that: /some/file exists on remote-machine. I can SSH normally from remote-machine to local-machine using my SSH key without any problems! I can run the command DISPLAY=:0.0 gedit sftp://remote-machine/some/file in a terminal on local-machine and gedit opens the file on remote-machine without any problems - but the terminal in which I executed the command is running in DISPLAY :0 (really, it's gnome-terminal). I also tried -t option of SSH client (to force pseudo-tty allocation) but it didn't work. If I try to run DISPLAY=:0.0 gedit sftp://remote-machine/some/file in local-machine but under a tty (for example in tty1, by pressing <Ctrl>+<Alt>+<F1>) it doesn't not work - I get the same error when running from remote-machine. I found that if I pass the environment variable DBUS_SESSION_BUS_ADDRESS with a correct value, it works! So, if I do something like that: myuser@local-machine:~$ env | grep DBUS_SESSION_BUS_ADDRESS > env.txt myuser@local-machine:~$ scp env.txt remote-machine: and then: myuser@remote-machine:~$ ssh local-machine "DISPLAY=:0.0 $(cat env.txt) gedit sftp://remote-machine/some/file" it works! The problem is that I'm not on local-machine so I can't get the correct value for this env variable. Is there any other way to make this work?
