  • Using GUI ftp on Win7 and Vista without additional software

    - by Stephen Jones
    Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

  • Windows Remote Desktop: "configuring remote session" closes without error

    - by icelava
    I have a desktop/laptop pair at home operating x64 Windows 7 (the desktop was upgraded from Windows Vista, works just fine). I remote desktop to them on a daily basis when outside. In recent weeks, I would occasionally fail to connect to my desktop. It can connect and authenticate fine, but the "configuring remote session" dialog would simply close and not show me the desktop window or any error message. There is no error event log relating to this on the desktop computer. Some suggestions call for disabling remote audio, which mine already is, but trying different audio modes did not yield any different result. I am not too sure if this is related to video card drivers (they do get auto-updated), since remote desktop video is supposed to steer via a virtual device driver? Nonetheless the desktop operates three monitors via an ATI Radeon HD5770 (1 Displayport, 2 DVI). I do not see a real problem with that since I can mostly connect and operate it remotely. I try to "remote tunnel" via my home laptop but obviously won't work either as the problem lies in the desktop. What other conditions can cause remote desktop to break without error? UPDATE I came home and still couldn't connect to the desktop until I restarted the entire system.

  • Ways to have audio output without wires

    - by viraptor
    I'm trying to find a way of using my home speakers/amp without actually having to connect them. There are two laptops that use them normally (so I don't like changing the connection all the time) and I'd rather move the speakers to a place that's away from the couch. I'm not sure how to do this though... The options I can think of are: some kind of wireless jack-jack connection finally getting a media server Unfortunately I can't find any good product for the first solution. I've seen some headphones which have the receiver integrated and a separate transmitted, so in general the idea is already out there, just not the way I need ;) I've seen also http://www.miccus.com/products/blubridge-mini-jack, but I'd have to have a compatible receiver which I can't find on its own (maybe there's some application that the media server could use?). As far as media server goes... many of the plug servers look really interesting, but I'm not sure how to create an audio output and how to redirect the input really. None of the plug servers I've seen so far advertises the option of audio output jack port. I think this part could be fixed by getting one with an usb port and a separate cheap usb soundcard. I hope that input can be sorted out in some rather simple way. I've got Linux running on both laptops so I hope that would be possible to configure jack/pulse/whatever to use the remote endpoint, or even write a simple local-/dev/dsp:network:media-server-/dev/dsp forwarder. So the main question is... are there better ways? Are there any out of the box solutions? Or maybe this was already done by someone and described somewhere?

  • ZFS with L2ARC (SSD) slower for random seeks than without L2ARC

    - by Florian Kruse
    I am currently testing ZFS (Opensolaris 2009.06) in an older fileserver to evaluate its use for our needs. Our current setup is as follows: Dual core (2,4 GHz) with 4 GB RAM 3x SATA controller with 11 HDDs (250 GB) and one SSD (OCZ Vertex 2 100 GB) We want to evaluate the use of a L2ARC, so the current ZPOOL is: $ zpool status pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM afstank ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c11t0d0 ONLINE 0 0 0 c11t1d0 ONLINE 0 0 0 c11t2d0 ONLINE 0 0 0 c11t3d0 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c13t0d0 ONLINE 0 0 0 c13t1d0 ONLINE 0 0 0 c13t2d0 ONLINE 0 0 0 c13t3d0 ONLINE 0 0 0 cache c14t3d0 ONLINE 0 0 0 where c14t3d0 is the SSD (of course). We run IO tests with bonnie++ 1.03d, size is set to 200 GB (-s 200g) so that the test sample will never be completely in ARC/L2ARC. The results without SSD are (average values over several runs which show no differences) write_chr write_blk rewrite read_chr read_blk random seeks 101.998 kB/s 214.258 kB/s 96.673 kB/s 77.702 kB/s 254.695 kB/s 900 /s With SSD it becomes interesting. My assumption was that the results should be in worst case at least the same. While write/read/rewrite rates are not different, the random seek rate differs significantly between individual bonnie++ runs (between 188 /s and 1333 /s so far), average is 548 +- 200 /s, so below the value w/o SSD. So, my questions are mainly: Why do the random seek rates differ so much? If the seeks are really random, they should not differ much (my assumption). So, even if the SSD is impairing the performance it should be the same in each bonnie++ run. Why is the random seek performance worse in most of the bonnie++ runs? I would assume that some part of the bonnie++ data is in the L2ARC and random seeks on this data performs better while random seeks on other data just performs similarly like before.

  • Motion - takes snapshot without motion detected

    - by Emmanuel Brunet
    I've been installed the standard motion 3.2.12 package on debian 7.5.

  • SharePoint, Exchange and Incoming Emails Without Directory Management Services

    - by Nariman
    Trying to keep this as simple as possible. We've already created the email accounts that we need (e.g. account[1-20]@domain.com) on Exchange/AD. We'd like to now enable incoming emails on SharePoint 2007 lists corresponding to these accounts. My thinking is we don’t need to configure Directory Management Services [2] – the architecture will be simpler without it and the application doesn’t require these services. However, we still need to route messages from Exchange to either local SMTP services (via the connector described in the articles below) or by user-specific drop-folder settings (if permitted by Exchange). So the question is: can we instruct Exchange to use a drop folder just for accounts account[1-20]@domain.com? or do we need to change the accounts to account[1-20]@sharepointsmtp.domain.com and re-route those message to the local SMTP service that will drop them on disk? I've read the material below.

  • Use WSUS without client configuration

    - by sc911
    Hello *, is there any way to let client-PCs use the local WSUS-server without having to configure them? What we need is a system to update PCs before they are delivered to the users. So the WSUS-server is accessible only within our lab, not later on at the users place. We'd like to use WSUS because it will fasten up the download very much. And we don't like to modify the clients as those changes might be forgotten to remove and then at the users place no update will be possible. So the easiest way would be, if one could redirect the normal Microsoft update, but I'm pretty sure that this will not be possible as this update will not be WSUS compliant. An other option I thought of might be, that the DHCP delivers an extra option telling the clients where to get the updates. But I could not find any information about this, so it looks like that this isn't possible too. So, is there any way? Or will it be easier to use a little script to change the WSUS-entries automatically? Regards sc911

  • How to log kernel panics without KVM

    - by Spacedust
    My server is crashing and I can't find an answer why. It all started after my datacenter upgrade RAM from 16 GB to 32 GB. I also found such logs in dmesg - they've started to show itself just before the first kernel panic: EXT4-fs error (device md2): ext4_ext_find_extent: bad header/extent in inode #97911179: invalid magic - magic 5f69, entries 28769, max 26988(0), depth 24939(0) EXT4-fs error (device md2): ext4_ext_remove_space: bad header/extent in inode #97911179: invalid magic - magic 5f69, entries 28769, max 26988(0), depth 24939(0) EXT4-fs error (device md2): ext4_mb_generate_buddy: EXT4-fs: group 20974: 8589 blocks in bitmap, 54896 in gd JBD: Spotted dirty metadata buffer (dev = md2, blocknr = 0).

  • Configure IIS to pass-through CGI output without any conditioning

    - by Daniel Watrous
    I'm building a web service on Windows 2008 R2 with IIS 7.5 and Python 2.5. Right now I have the Handler Mappings and everything else setup just fine, Except that IIS is modifying what it gets back from the CGI script before sending it along the the client. Here's an example: I wrote the following CGI script: # hello.py print "Status: 400 Bad Request" print "Content-Type: text/html" print print "Error Message" According to the HTTP spec this should be fine and a Status of 400 should allow for a description of the error message in the body of the response. When the server response actually comes back to me I get the following: Status: 400 Bad Request Date: Fri, 11 Feb 2011 17:58:30 GMT X-Powered-By: ASP.NET Connection: close Content-Length: 11 Server: Microsoft-IIS/7.5 Content-Type: text/html Bad Request I've seen on this forum and others where I can change or eliminate the X-Powered-By header element, but I would like IIS to leave it alone altogether. I'm not sure why it takes my response, deletes "Error Message" from the body and replaces it with "Bad Request" and then adds all that other junk in. Is there some way to tell IIS to just send the response along without making any changes at all?

  • Removing extended partition without deleting logical in it

    - by HisDudeness
    I'm running a Linux-based laptop, and in order to multi-boot several distros in it, I created an extended partition which contains a bunch of logical ones with GParted. Now, after quite a long time with this setup, I've changed my mind because of the consequent lack of storing space for my data partition. Now I want to keep one distro alone like it's normal, and eventually have some other operating systems stored in external supports to plug in and use if I want. Obviously, also this partition I want to keep (and to enlarge a little too) is just a logical inside the extended I want to keep. For what concerns the number I'm ok, meaning I currently have this big distro dedicated extended, the swap and the data partitions, so there's space for another primary before I delete the extended, but I don't know how to delete it without touching the logical in it, I don't want to reinstall the system losing all changes and settings, and I don't want to keep an extended partition for a logical alone. How can I do? Do I have to create a new primary, copy the logical content in it and then delete everything? Will the system boot and maintain exactly all the features it has now? Or is there a way to convert an extended into a primary once it contains just one logical? Or can I directly move a logical out of an extended turning it into a primary? Or, again, am I screwed?

  • running a command as root with /bin/su and without gives different results

    - by n00bInCpp
    Some background: I have a machine with SLES 11 installed. I am running a bash script that one of its lines is /bin/su $USER -c SOME_CMD. Unfortunately, the SOME_CMD that comes after the -c keeps failing, no matter if USER=root or any different user. However, if /bin/su $USER -c part is omitted then everything runs smoothly. Moreover, I have run the script on RHEL5 and it worked fine. Anyway, my question is why does it happen? If it is a permissions problems then why when I run this as root with /bin/su and without I get different results? P.S. apologize if somebody else has asked it before, I have done many googling and got nothing that satisfies. Thanks in advance, n00bInCpp EDIT Okay, I figured it out, I hope so. Instead of running /bin/su I used /user/bin/sudo -u $MY_USER_1 MY_ENV_VAR="/home/user1" SOME_CMD. I don't understand why I have to use sudo, though. I am used to run a command as a different user using su and not worrying about permissions problems, but I guess it doesn't work like that on SLES 11/SuSE. Anyhow, thanks to everyone who wanted to or helped me.

  • Flash Backed Write Cache (FBWC) without capacitor pack

    - by Martyn
    I brought a HP Smart Array P410 controller and it is installed and working fine in a HP Prolient Microserver with 4 drives in two RAID 1 arrays. I didn’t realise however that it came without any cache so would only work by directly writing straight to the disk, and the performance was horrible. So I then brought the 512MB Flash Backed Write Cache (FBWC) memory module as I was under the impression that with FBWC I would not need a battery. I got this idea from a forum post. "What do you guys think of the choice between 'BBWC' (battery backed write cache) and 'FBWC' (flash backed write cache)? The flashed based ones use non-volitile memory so need no battery." After installing the cache module however the server pretty much won’t boot. The P410 has a flashing amber light on it, and from the manual that doesn’t sound good. I’ve managed to get to the on board BIOS once and even managed to get to boot to the HP Array Configuration Utility (ACU) CD once, but every other time the Server continuingly reboots once it get to the POST screen and reads ARRAY INITILIZING %%%. The one time I reached the ACU, it reported a problem with the Cache Module. To me, it seems like the cache module is faulty, however the supplier tells me “Do you have an FBWC battery pack, p/n 587324-001, because that is required for the cache to work. If you have it, please complete an RMA form and we'll send a replacement / credit.” Does this sound right to you? I’ve been ordering the parts from the US and I don’t want to spend $77 + $40 p&p on a battery, wait a week for the shipping to find the card is faulty, and I don’t want to send back a working card?

  • Restoring MBR, partition table, and boot sector of memory card without data loss ("USBC")

    - by Synetech
    Abstract I have a FAT32 memory card that when inserted into a computer causes Windows to prompt to format it. The card is definitely not supposed to be blank and has a bunch of files on it. Symptoms Using a hex-editor/disk-viewer, I examined the card and found that several sectors/clusters have been overwritten with something that has a signature of USBC at the start of the sector. Specifically, the master boot record (and partition table) is gone (hence Windows thinking the card is blank and needing to be formatted), as are the boot sectors (they have the USBC signature and a volume label of NO NAME and partition type of FAT32). Fortunately, it looks like both copies of the FAT are almost entirely intact (a few FAT entries at the start of a cluster here and there seem to be overwritten by USBC). The root directory is also nearly intact—I can see the volume label entry and subdirectory listings, but one sector is overwritten. (There are no more instances of USBC after the last one in the FAT2.) Hypothesis These observations seem to indicate some sort of virus that erases a few key filesystem structures, and then overwrites a few extra sectors here and there. Googling it seems to corroborate the idea of a virus, except that others report a file called USBC which does not apply here, and in fact, could not be possible since there is no filesystem to even see files. I cannot find any information about a virus with these symptoms, nor a removal tool. (I can't help but wonder if it is actually due to an autorun virus prevention tool.) Question I can likely fix the FAT corruption since they are mostly contiguous chains and maybe even the lost sector of the root directory, but does anyone know of a convenient way to restore or (re)create the MBR/partition table and boot sectors (without formatting or overwriting the data)?

  • Force delivery retry without restarting the SMTP Service on Windows Server 2008 R2

    - by Mathias R. Jessen
    I have a Windows Server 2008 R2 box hosting 3 virtual SMTP servers; vSMTP01, vSMTP02 and vSMTP03. The first two are configured to deliver all messages to dedicated smarthosts, while the last is set to just deliver the messages on its own. All other delivery settings are as default ----(vSMTP01)-----> {SMARTHST01} / ----Inbound mail--->---SMTPSRV01---[----(vSMTP02)-----> {SMARTHST02} \ ----(vSMTP03)-----> { Internet } Now I want to take SMARTHST01 out for maintenance, but I don't want to reject submissions to vSMTP01 while doing so, so I just let it continue running. When SMARTHST01 is no longer responding, vSMTP01 queues the messages and wait for the first retry interval to pass (15 minutes). So far so good. Let's say SMARTHST01 gets online again after 20 minutes. The first interval has passed, and I'll have to wait another 25 minutes for the second retry interval to pass. If I stop and start the SMTP Service (Services.msc - Simple Mail Transfer Protocol service - Stop), the server will retry all deliveries, but that would cause a service interruption for ALL virtual SMTP servers on the machine, which is highly undesirable. How can I manually force vSMTP01 to retry delivery of all queued messages without interrupting the service of vSMTP02 and vSMTP03?

  • Use old raid drive as boot device without data loss

    - by Gabriel
    There were two disks in sw-raid. There were /dev/md1 as swap, /dev/md2 as boot and a /dev/md3 with ext4. The sw-raid was disabled by stopping and removing mdadm and then zeroing the superblock on each /dev/mdX partition with: sudo mdadm --zero-superblock /dev/sda1 sudo mdadm --zero-superblock /dev/sda2 sudo mdadm --zero-superblock /dev/sda3 In the disk that is the first boot device, I don't know if it's relevant, the system type of each partition was set back from fd to 82 or 83 with fdisk, /etc/fstab was updated, changing /dev/mdX to /dev/sdaX, and grub was reinstalled on the boot partition (/dev/sda2) with grub-instal. But the system wont boot. What else should I do to use this disk as the boot device without reinstall or data loss?

  • Active Directory server down, recovering without reinstalling

    My Windows 2003 server suddenly ceased to function as a DC (this server is the only DC of the domain). All AD related services are down. The only way I can login to the AD is physically to the machine. Everytime I access an AD-related service (e.g. "AD users and computers") I get the below error: Naming information cannot be located because: The specified directory service attribute or value does not exist. Contact your system administrator to verify that your domain is properly configured and is currently online. I found the below system event which matches the time when the issue started, this re-occurs everytime I reboot the server. NTDS General | Global Catalog | Active Directory was unable to establish a connection with the global catalog. Additional Data Error value: 1355 The specified domain either does not exist or could not be contacted. Internal ID: 3200d33 I started the troubleshooting with DNS. Netdiag throws the below error although I think this is simply a consequence of not being able to access the Global Catalog. The procedure entry point DnsGetPrimaryDomainName_UTF8 could not be located in the dynamic link library DNSAPI.dll. Anyway DNS seems OK because I can ping the DC FQDN from the DC itself. I found the below solution which is supposed to help by doing some cleanup of the metadata: http://support.microsoft.com/kb/216498 If I follow procedure 1 here is what I get at step 9: no current site Domain - DC=<mydomain>,DC=<com> no current server no current naming context I can continue the procedure until step 14. I haven't tested step 15 as my understanding is that I will have to reinstall the whole AD again. Is there any way I can recover my AD from there without having to reinstall the whole thing? Update: Yes, the server was powered off/on because reboot would take forever (not because I thought power cycling the unit would fix it more than a reboot).

  • Configure X connections over TCP without using an X connection

    - by Darren Cook
    I want to run a GUI application on a remote machine I only have ssh access to. I don't need to, or want to, see the GUI window. (I know I could use something like ssh -C -X remote_server if I wanted the GUI to be on my client.) I know X is running on the remote machine, as ps shows this: root ... /usr/bin/Xorg :0 -br -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7 I set DISPLAY=:0.0 but I then get "Xlib: connection to ":0.0" refused by server" when I try to use it. At Get remote x display working in linux without ssh tunneling and Xserver doesn't work unless DISPLAY=0.0 I see the advice to use gdmsetup to allow X to listen on TCP. But, gdmsetup is a GUI application! And trying to run it over ssh -X did not work ("X11 connection rejected because of wrong authentication"). So, is there a text file I can edit to remove -nolisten? And, after editing it, how do I safely restart X, remotely? (There is other stuff running on this machine, so requesting a reboot is possible, but undesirable.) If not, should gdmsetup be able to run over ssh and I should persevere in that direction? UPDATE: I had to do the ssh -X session as root (ssh as a normal user, then sudo or su, does not work.) So, I did the edit with gdmsetup. I then restarted X with gdm-restart. I've also done xhost + from that ssh -X session. The ps line no longer shows the -nolisten tcp part. But still no luck connecting to it, with either DISPLAY=:0 or DISPLAY=localhost:0

  • Redirect without changing URL

    - by Coobadivin
    Here's the setup. We have a hardware load balancer with an http virtual cluster. Let's call this virtual cluster example1.com. This virtual cluster load balances between two squid reverse proxies which are also on the same physical servers as the web servers. Squid listens on 80 and points to itself as the cache_peer web server which listens on 81. We also have a standalone web server which we will call example2.com. What we are trying to do is create a subdirectory on example1.com called example1.com/example2. This will point to example2.com, but we want our users to stay at example1.com/example2 in their browser. So, it's like a redirect without actually being a redirect. How the hell do I go about doing this? Is this even possible? I'm looking at squid docs in the meantime. example1.com is running a proprietary web server - not Apache :( We can't host example2.com's content in example1.com's file system. These are two very different platforms.

  • Apache forwarding without redirecting (application won't follow redirects)

    - by DrewVS
    Recently we had to move /task to /public/task, and I'd like to configure Apache to redirect accordingly. However, using mod_rewrite, though it works in the browser, seems to break applications making api calls to the above location. What happens is the application returns a page with the message saying the page was moved, but the app doesn't follow the redirect. So, is there a way to simply forward any traffic to /task to /public/task without 'redirecting', i.e, returning a redirect status code? EDIT: Here's a little more information. I've found a simple test to clarify what I'm trying to fix. Here is the URL path that needs forwarding: https://mydomain.com/task Needs to go to: https://mydomain.com/public/task If I use curl against the original domain, it just returns a redirect page notice. If I add the -L flag, which tells curl to follow redirects, it then follows the redirect successfully. I assume something very similar is happening in the application (which I don't have access to) that makes calls to the /task URL path. Since I cannot modify the application to make it follow redirects properly, I'm looking for a solution I can implement in Apache.

  • Windows scroll without focus

    - by DanielCardin
    So I have a windows 8 laptop at home, and a windows 7 laptop at work. Both have synaptics touchpads. The problem is that on the work laptop, I can scroll any window regardless of which one is currently focused. That is the behavior that I want on both computers. This does not currently happen on the windows 8 computer. I know I can use (and have tried!) wizmouse, alwaysmousewheel, katmouse, etc; but none of them work 100% like the work computer. katmouse sometimes stops working, alwaysmousewheel, ive had problems with it scrolling on its own, wizmouse sometimes makes the mouse lag. Others have just not worked. Before I got the work computer, I had resigned myself to it, but now I see that it works, out of the box without using any external programs, on an older operating system, and wonder why I cant get it to work the same way on my own computer! All my searches have just been people suggesting the external programs that ive already tried, so answers suggesting those aren't really what I'm looking for (unless its some magic I can do with the synaptics driver, which by the way is more up to date on the windows 8 computer that is doesnt work on).

  • Run CGI in IIS 7 to work with GET without Requiring POST Request

    - by Mohamed Meligy
    I'm trying to migrate an old CGI application from an existing Windows 2003 server (IIS 6.0) where it works just fine to a new Windows 2008 server with IIS 7.0 where we're getting the following problem: After setting up the module handler and everything, I find that I can only access the CGI application (rdbweb.exe) file if I'm calling it via POST request (form submit from another page). If I just try to type in the URL of the file (issuing a GET request) I get the following error: HTTP Error 502.2 - Bad Gateway The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are "Exception EInOutError in module rdbweb.exe at 00039B44. I/O error 6. ". This is a very old application for one of our clients. When we tried to call the vendor they said we need to pay ~ $3000 annual support fee in order to start the talk about it. Of course I'm trying to avoid that! Note that: If we create a normal HTML form that submits to "rdbweb.exe", we get the CGI working normally. We can't use this as workaround though because some pages in the application link to "rdbweb.exe" with normal link not form submit. If we run "rdbweb.exe". from a Console (Command Prompt) Window not IIS, we get the normal HTML we'd typically expect, no problem. We have tried the following: Ensuring the CGI module mapped to "rdbweb.exe".in IIS has all permissions (read, write, execute) enabled and also all verbs are allowed not just specific ones, also tried allowing GET, POST explicitely. Ensuring the application bool has "enable 32 bit applications" set to true. Ensuring the website runs with an account that has full permissions on the "rdbweb.exe".file and whole website (although we know it "read", "execute" should be enough). Ensuring the machine wide IIS setting for "ISAPI and CGI Restrictions" has the full path to "rdbweb.exe".allowed. Making sure we have the latest Windows Updates (for IIS6 we found knowledge base articles stating bugs that require hot fixes for IIS6, but nothing similar was found for IIS7). Changing the module from CGI to Fast CGI, not working also Now the only remaining possibility we have instigated is the following Microsoft Knowledge Base article:http://support.microsoft.com/kb/145661 - Which is about: CGI Error: The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: the article suggests the following solution: Modify the source code for the CGI application header output. The following is an example of a correct header: print "HTTP/1.0 200 OK\n"; print "Content-Type: text/html\n\n\n"; Unfortunately we do not have the source to try this out, and I'm not sure anyway whether this is the issue we're having. Can you help me with this problem? Is there a way to make the application work without requiring POST request? Note that on the old IIS6 server the application is working just fine, and I could not find any special IIS configuration that I may want to try its equivalent on IIS7.

  • disk-to-disk backup without costly backup redundancy?

    - by AaronLS
    A good backup strategy involves a combination of 1) disconnected backups/snapshots that will not be affected by bugs, viruses, and/or security breaches 2) geographically distributed backups to protect against local disasters 3) testing backups to ensure that they can be restored as needed Generally I take an onsite backup daily, and an offsite backup weekly, and do test restores periodically. In the rare circumstance that I need to restore files, I do some from the local backup. Should a catastrophic event destroy the servers and local backups, then the offsite weekly tape backup would be used to restore the files. I don't need multiple offsite backups with redundancy. I ALREADY HAVE REDUNDANCY THROUGH THE USE OF BOTH LOCAL AND REMOTE BACKUPS. I have recovery blocks and par files with the backups, so I already have protection against a small percentage of corrupt bits. I perform test restores to ensure the backups function properly. Should the remote backups experience a dataloss, I can replace them with one of the local backups. There are historical offsite backups as well, so if a dataloss was not noticed for a few weeks(such as a bug/security breach/virus), the data could be restored from an older backup. By doing this, the only scenario that poses a risk to complete data loss would be one where both the local, remote, and servers all experienced a data loss in the same time period. I'm willing to risk that happening since the odds of that trifecta negligibly small, and the data isn't THAT valuable to me. So I hope I have emphasized that I don't need redundancy in my offsite backups because I have covered all the bases. I know this exact technique is employed by numerous businesses. Of course there are some that take multiple offsite backups, because the data is so incredibly valuable that they don't even want to risk that trifecta disaster, but in the majority of cases the trifecta disaster is an accepted risk. I HAD TO COVER ALL THIS BECAUSE SOME PEOPLE DON'T READ!!! I think I have justified my backup strategy and the majority of businesses who use offsite tape backups do not have any additional redundancy beyond what is mentioned above(recovery blocks, par files, historical snapshots). Now I would like to eliminate the use of tapes for offsite backups, and instead use a backup service. Most however are extremely costly for $/gb/month storage. I don't mind paying for transfer bandwidth, but the cost of storage is way to high. All of them advertise that they maintain backups of the data, and I imagine they use RAID as well. Obviously if you were using them to host servers this would all be necessary, but for my scenario, I am simply replacing my offsite backups with such a service. So there is no need for RAID, and absolutely no value in another layer of backups of backups. My one and only question: "Are there online data-storage/backup services that do not use redundancy or offer backups(backups of my backups) as part of their packages, and thus are more reasonably priced?" NOT my question: "Is this a flawed strategy?" I don't care if you think this is a good strategy or not. I know it pretty standard. Very few people make an extra copy of their offsite backups. They already have local backups that they can use to replace the remote backups if something catastrophic happens at the remote site. Please limit your responses to the question posed. Sorry if I seem a little abrasive, but I had some trolls in my last post who didn't read my requirements nor my question, and were trying to go off answering a totally different question. I made it pretty clear, but didn't try to justify my strategy, because I didn't ask about whether my strategy was justifyable. So I apologize if this was lengthy, as it really didn't need to be, but since there are so many trolls here who try to sidetrack questions by responding without addressing the question at hand.

  • Logging to MySQL without empty rows/skipped records?

    - by Lee Ward
    I'm trying to figure out how to make Squid proxy log to MySQL. I know ACL order is pretty important but I'm not sure if I understand exactly what ACLs are or do, it's difficult to explain, but hopefully you'll see where I'm going with this as you read! I have created the lines to make Squid interact with a helper in squid.conf as follows: external_acl_type mysql_log %LOGIN %SRC %PROTO %URI php /etc/squid3/custom/mysql_lg.php acl ex_log external mysql_log http_access allow ex_log The external ACL helper (mysql_lg.php) is a PHP script and is as follows: error_reporting(0); if (! defined(STDIN)) { define("STDIN", fopen("php://stdin", "r")); } $res = mysql_connect('localhost', 'squid', 'testsquidpw'); $dbres = mysql_select_db('squid', $res); while (!feof(STDIN)) { $line = trim(fgets(STDIN)); $fields = explode(' ', $line); $user = rawurldecode($fields[0]); $cli_ip = rawurldecode($fields[1]); $protocol = rawurldecode($fields[2]); $uri = rawurldecode($fields[3]); $q = "INSERT INTO logs (id, user, cli_ip, protocol, url) VALUES ('', '".$user."', '".$cli_ip."', '".$protocol."', '".$uri."');"; mysql_query($q) or die (mysql_error()); if ($fault) { fwrite(STDOUT, "ERR\n"); }; fwrite(STDOUT, "OK\n"); } The configuration I have right now looks like this: ## Authentication Handler auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 30 auth_param negotiate program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param negotiate children 5 # Allow squid to update log external_acl_type mysql_log %LOGIN %SRC %PROTO %URI php /etc/squid3/custom/mysql_lg.php acl ex_log external mysql_log http_access allow ex_log acl localnet src 172.16.45.0/24 acl AuthorizedUsers proxy_auth REQUIRED acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl CONNECT method CONNECT acl blockeddomain url_regex "/etc/squid3/bl.acl" http_access deny blockeddomain deny_info ERR_BAD_GENERAL blockeddomain # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # Allow the internal network access to this proxy http_access allow localnet # Allow authorized users access to this proxy http_access allow AuthorizedUsers # FINAL RULE - Deny all other access to this proxy http_access deny all From testing, the closer to the bottom I place the logging lines the less it logs. Oftentimes, it even places empty rows in to the MySQL table. The file-based logs in /var/log/squid3/access.log are correct but many of the rows in the access logs are missing from the MySQL logs. I can't help but think it's down to the order I'm putting lines in because I want to log everything to MySQL, unauthenticated requests, blocked requests, which category blocked a specific request. The reason I want this in MySQL is because I'm trying to have everything managed via a custom web-based frontend and want to avoid using any shell commands and access to system log files if I can help it. The end result is to make it as easy as possible to maintain without keeping staff waiting on the phone whilst I add a new rule and reload the server! Hopefully someone can help me out here because this is very much a learning experience for me and I'm pretty stumped. Many thanks in advance for any help!
