  • What is the best way to remove duplicate files on web hosting's FTP server?

    - by Eric Harrison
    For some reason(Happened before I started working on this project)- my client's website has 2 duplicates of every single file. Effectively tripling the size of the site. The files look much like this: wp-comments-post.php | 3,982 bytes wp-comments-post (john smith's conflicted copy 2012-01-12).php | 3,982 bytes wp-comments-post (JohnSmith's conflicted copy 2012-01-14).php | 3,982 bytes The hosting that the website is on has no access to bash or SSH. In your opinion, what would be the easiest way to delete these duplicate files that would take the least time?

  • What is the best place to setup system wide environment variables on Linux?

    - by Sorin Sbarnea
    I just want to setup a system wide environment variable, JAVA_HOME for all users, including root user. Requirements: accessible to normal users accessible to root always loaded, not only for bash (gnome-terminal does not start a bash by default) to work on Ubuntu, Debian and optionally Red Hat great if addition could be easily scripted So far here is the no-list: /etc/profile.d/java.sh - not executed if you start a new console from gnome-terminal /etc/profile - same as above ~/.profile - current user only, also any solution assuming ~ would not be acceptable because home directory could be on NIS, and JAVA_HOME could be different.

  • What is the best way to solve an Objective-C namespace collision?

    - by Mecki
    Objective-C has no namespaces; it's much like C, everything is within one global namespace. Common practice is to prefix classes with initials, e.g. if you are working at IBM, you could prefix them with "IBM"; if you work for Microsoft, you could use "MS"; and so on. Sometimes the initials refer to the project, e.g. Adium prefixes classes with "AI" (as there is no company behind it of that you could take the initials). Apple prefixes classes with NS and says this prefix is reserved for Apple only. So far so well. But appending 2 to 4 letters to a class name in front is a very, very limited namespace. E.g. MS or AI could have an entirely different meanings (AI could be Artificial Intelligence for example) and some other developer might decide to use them and create an equally named class. Bang, namespace collision. Okay, if this is a collision between one of your own classes and one of an external framework you are using, you can easily change the naming of your class, no big deal. But what if you use two external frameworks, both frameworks that you don't have the source to and that you can't change? Your application links with both of them and you get name conflicts. How would you go about solving these? What is the best way to work around them in such a way that you can still use both classes? In C you can work around these by not linking directly to the library, instead you load the library at runtime, using dlopen(), then find the symbol you are looking for using dlsym() and assign it to a global symbol (that you can name any way you like) and then access it through this global symbol. E.g. if you have a conflict because some C library has a function named open(), you could define a variable named myOpen and have it point to the open() function of the library, thus when you want to use the system open(), you just use open() and when you want to use the other one, you access it via the myOpen identifier. Is something similar possible in Objective-C and if not, is there any other clever, tricky solution you can use resolve namespace conflicts? Any ideas? Update: Just to clarify this: answers that suggest how to avoid namespace collisions in advance or how to create a better namespace are certainly welcome; however, I will not accept them as the answer since they don't solve my problem. I have two libraries and their class names collide. I can't change them; I don't have the source of either one. The collision is already there and tips on how it could have been avoided in advance won't help anymore. I can forward them to the developers of these frameworks and hope they choose a better namespace in the future, but for the time being I'm searching a solution to work with the frameworks right now within a single application. Any solutions to make this possible?

  • Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

    - by ProfessionalAmateur
    I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

  • What is the best server or Ip address to use for prolonged testing?

    - by eldorel
    I usually run uptime/latency tests against (and from) two servers that we own at different sites and until recently I've used the google dns servers as a control group. However, I've realized there is a potential problem with monitoring latency over extended periods of time. Almost all of the major service providers are using ANYCAST. For short tests this doesn't matter, but I need to run a set of tests for at least a week to try and catch an intermittent problem, and a change in the anycast priority while trying to test latency will cause the latency values for that server to change accordingly. Since I'm submitting graphs of this data to the ISP, I need to avoid/account for as many variables as possible. Spikes in the data for only one of the tested servers will only cause headaches. So can anyone recommend servers that: are not using anycast are owned by an entity that has a good uptime reputation (so they can't claim that the problem is server-side) will respond to ICMP requests Have an available service that runs on TCP/UDP (http or dns preferably) Wont consider an automated request every 10 minutes to be abuse Are accessible from anywhere in the world Are not local to the isp ( consider this an investigation of a hostile party ) Thanks in advance. Edit: added #6 and #7 above. More info: I am attempting to demonstrate a network problem for an entire node of our local ISP's network. They are actively blaming the issue on the equipment installed at the customer sites (our backup site is one of these), and refuse to escalate the problem. (even though 2 of these businesses have ISP provided modems, and all of us have completely different routers/services running) I am already quite familiar with the need to test an isp controlled IP, but they are actively dropping all packets targeted at gateway ip addresses and are only passing traffic addressed beyond the gateways. So to demonstrate the issue, I am sending packets to other systems in the same node, systems one hop away from the affected node, and systems completely outside the network. Unfortunately, all of the systems I have currently are either administered directly by myself, or by people who are biased enough to assist me. I need to have several systems included in the trace/log/graphs that are 100% not in the control of either myself or the isp so that the graphs have a stable/unbiased control group. These requirements are straight from legal, I'm just trying to make sure that everything that could be argued to invalidate the data is already covered. In Summary: I need to be able to show tcp/udp/icmp as 3 separate data points, and I need to be able to show the connections inside the local node, from local node to another nearby node, from those 2 nodes to the internet, and through the internet to both verifiable servers and a control group that I have no control over whatsoever. Again, Google/opendns/yahoo/msn/facebook/etc all use anycast, which throws the numbers off every time the anycast caches expire, so I need suggestions of an IP or server that is available for this type of testing. I was hoping someone knew of a system run by someone such as ISC or ICANN, or perhaps even a .gov server (fcc or nsa maybe?) setup for this type of testing. Thanks again.

  • What's the best NAME for "quick" Category you add to a file?

    - by Joe Blow
    So the other day I was sick of typing out repetetive addTarget:action:forControlEvents:s, and macros are only entertaining for so long, so I did this: @implementation UIControl (xx) -(void)addTarget:(id)target action:(SEL)action { [self addTarget:target action:action forControlEvents:UIControlEventTouchUpInside]; } @end *and simply added it at the top of the .m file in question. Works great of course, but notice the "xx".* What's the best thing to NAME a "quick" Category like this? Annoyingly, it appears you can not leave the xx blank - it would then become an "Extension" (which, incidentally, I don't understand at all). I was thinking maybe: a single underscore the name of the class again identically "quick" perhaps the name of the class in this file (as in "quick extra routines for UIControl in CherryBomb") - so it would be UIControl(CherryBomb), ie, remind you that these extra routines are handy for CherryBomb "x" your or your company's initials (use the same "quick" Category name everywhere) "ThisTextNeverUsedAnywhere" By the way, I've been assuming that Categories only happen in the files that see them (CherryBomb.m in the example) - they do not from then on apply app-wide. ie they only apply where you include the header file (UIControl+NattyStuff) or in the "quick" case only in the file to which one adds the text. (By the way ... it appears you do not actually need to include an interface for such a Category, i.e. you can omit... //you can actually get away without these lines... //#import <UIKit/UIControl.h> //@interface UIControl (x) //-(void)addTarget:(id)target action:(SEL)action; //@end ... that part and it works fine.) For people who love Categories, and who doesn't, what's the answer to this troubling question? What should you name a "quick" Category where the name is never going to be referenced again and is irrelevant? Is "_" a solution?

  • What is the best way to create RAID 1?

    - by user3125731
    I'm looking for a way to create the RAID 1 array without losing my data on CentOS. Here's my situation: I've got a web server running on CentOS. There is one VG partition with few LV volumes. I bought a second HDD (the same model and size as the first one) and I want to create the RAID 1 configuration. I can't just shut down this server for more than an hour because my clients will be disappointed. I need to do this as quickly as possible with minimal risk of data loss.

  • What's the best way to rewrite traffic from domainA.com/foo to domainB.com/bar while properly rewrit

    - by Chad DePue
    We have a number of sites that have blogs, like domainA.com/blog domainB.com/blog and we host the blogs on wordpress multi user: our-separate-wordpress-site.com/domaina_blog our-separate-wordpress-site.com/domainb_blog for SEO reasons we really, really want domainA.com/blog to be the blog url, not the other path. But we don't see any examples where this is done, because we need not to just rewrite the traffic, but cookies as well... is this possible with a webserver or a reverse proxy?

  • What is the best solution for letting both Macs and PCs access digital images and videos on a networ

    - by Gertbert
    I'm looking for a simple way to share digital images and videos over a network to both Macs and PCs. I'm currently looking into three options: NAS, WD MyBook Mirror drives attached to a router, or an HP WHS product like the Data Vault. I'm looking for something easy to implement that allows for drive mirroring but also has good performance for both Macs and PCS. I've read that the HP WHS devices rebalance on their own schedules, making them useless for streaming video, and hope someone can definitively confirm or deny this as it's a dealbreaker if true. Any other suggestions are appreciated. Thanks!

  • What is the best policy for user account on a Windows 7 Media Center shared by the whole family

    - by Matt Spradley
    What is a good way to manage user accounts for a Windows 7 Media Center PC that is part of an entertainment center for a family? Each family member keeps most of their personal stuff on their own computer. I was thinking the simple approach would be to create an admin account for management and then just create a "Family" user account w/o a password that is the default account used by the media center. This account would be used for the PVR, playing blu rays, music, etc. I don't think it is practical for someone to have to log in every time they use the media center.

  • Waht are the best proxy servers for Mikrotik router?

    - by niren
    I want to setup proxy server for my Mikrotik router. There is inbuilt web-proxy for Mikrotik router but I can extend this upto transparent proxy(kind of proxy server) only. We need High anonymity proxy so that we can hide our LAN static IPs(we don't have private IP) from outside Intruder/hackers. And also I know I can setup NAT rule to hide our IP(only private IP not public/static IP) as per this link, but I cann't hide static/public IP. Essentially I want to hide our Public/Static IP (there is static/public IP for all systems in our company) from outside Internet. To achieve this I guess I need other software apart from Mikrotik router gateway setup. can anyone suggest me Is there any other software to achieve my requirement? I know about squid proxy but am not sure whether It can hide our static/public IP. Note: we have assigned public/Static IP to all systems of our company since we have rights to access our company's system from anywhere by dedicated laptop(given by our company with more security) through VPN connection.

  • What the best way to recover from when your RAID H/W incorrectly thinks a disk is missing

    - by Software Monkey
    I have a Windows 7 system with an MSI motherboard (running the latest AMD BIOS) and two of my four disks (not the system boot disk) configured via the Mobo as RAID-1. After a normal system restart today, the RAID BIOS reports that one of the two drives has been disconnected or has failed. It's not really failed; via recovery tools I can verify that if I take the BIOS out of RAID mode. But I can find no way to re-add the second hard disk to the array and rebuild via the BIOS - the only option seems be to delete the array and recreate it, but I've done that once before and it blows away the disk. It's done this once before, however on a subsequent reboot after double-checking the drive cabling (but not changing anything) and it boot up fine. So I think the mobo RAID is a little bit flaky. At this point I would like to remove the RAID drivers, change to AHCI mode and switch over to using a Windows 7 dynamic mirror disk. But the RAID drivers seem somehow deeply bound into the Windows startup - I can't find anything like the good ol' safe-mode in Windows 7. If I boot from the Win 7 install disk in ACHI mode I can use recovery tools to log in to the Windows 7 installation, so the boot drive it seems fine with ACHI mode. Additionally, I can see all my other disks, run chkdsk on them and they seem to be fine. If I try to boot from the HDD in AHCI mode, it just reboots part way through, presumably because the RAID drivers load and conflict with the BIOS being set to AHCI. So: How do I strip the RAID drivers from my Win 7 installation? If I delete the RAID logical disk, will it really delete partitioning information, or is that just a poorly worded message when it says the data on the disk will be deleted? If I disconnect the 2 disks in a RAID array, then delete the logical disk array, and then reconnect and reboot still in RAID mode, will the disks simply revert to RAID single-disks like my other 2 and then maybe I can leave windows with RAID drivers by operate the disks as singles with 2 of them in a Windows dynamic disk mirrored setup? Does Windows 7 have anything like the Windows XP Repair Install, where it will reinstall the O/S binaries from CD, but leave apps and setup alone. I am really hoping I don't have to do a complete reinstall of Windows 7 - the last one, when I upgraded from XP, took me two days to get everything set up and installed.

  • What would be the best way to dynamically add a set of rows to a table using JQuery?

    - by user312157
    I have a following table using MVC that shows number of items the user has. <table border = "1" id="tblItems"> <% var itemnum = 1; foreach (var item in Model.Items) {%> <tr> <td colspan="2" bgcolor="Silver"><strong>Item#<%=itemnum%></strong></td> <td><%=Html.ActionLink("Delete", "DeleteItem", "Item", new { id = item.ID })%></td> </tr> <tr> <td><strong>Name:</strong></td> <td><%=Html.TextBox("ItemName_" + itemnum, item.Name)%></td> </tr> <tr> <td><strong>Description:</strong></td> <td><%=Html.TextBox("ItemDescription_" + itemnum, item.Description)%></td> </tr> <%itemnum++; } %> </table> I will have a button that will Add New Item that will dynamically add identical structure. Any ideas on what is the best way to do this using JQuery? Thanks for all the suggestions!

  • Best NIC config when virtual servers need iSCSI storage?

    - by icky2000
    I have a Windows 2008 server running Hyper-V. There are 6 NICs on the server configured like this: NIC01 & NIC02: teamed administrative interface (RDP, mgmt, etc) NIC03: connected to iSCSI VLAN #1 NIC04: connected to iSCSI VLAN #2 NIC05: dedicated to one virtual switch for VMs NIC06: dedicated to another virtual switch for VMs The iSCSI NICs are used obviously for storage to host the VMs. I put half the VMs on the host on the switch assigned to NIC05 and the other half on the switch assigned to NIC06. We have multiple production networks that the VMs could appear on so the switch ports that NIC05 & NIC06 are connected to are trunked and we then tag the NIC on the VM for the appropriate VLAN. No clustering on this host. Now I wish to assign some iSCSI storage direct to a VM. As I see it I have 2 options: Add the iSCSI VLANs to the trunked ports (NIC05 and NIC06), add two NICs to the VM that needs iSCSI storage, and tag them for the iSCSI VLANs Create two additional virtual switches on the host. Assign one to NIC03 and one to NIC04. Add two NICs to the VM that needs iSCSI storage and let them share that path to the SAN with the host. I'm wondering about how much overhead the VLAN tagging in Hyper-V has and haven't seen any discussion about that. I'm also a bit concerned that something funky on the iSCSI-connected VM could saturate the iSCSI NICs or cause some other problem that could threaten storage access for the entire host which would be bad. Any thoughts or suggestions? How do you configure your hosts when VMs connect direct to iSCSI?

  • Best way to find the computer a user last logged on from?

    - by Garrett
    I am hoping that somewhere in Active Directory the "last logged on from [computer]" is written/stored, or there is a log I can parse out? The purpose of wanting to know the last PC logged on from is for offering remote support over the network - our users move around pretty infrequently, but I'd like to know that whatever I'm consulting was updating that morning (when they logged in, presumably) at minimum. I'm also considering login scripts that write the user and computer names to a known location I can reference, but some of our users don't like to logout for 15 days at a time. If there is an elegant solution that uses login scripts, definitely mention it - but if it happens to work for merely unlocking the station, that would be even better!

  • What are the best tools for modeling a pre-existing SQL database structure?

    - by Ejoso
    I have a MS SQL database that has been running strong for 10+ years. I'd like to diagram the database structure, without spending hours laying it all out in Visio or something similar... I've seen nice models diagrammed before, but I have no idea how they were created. From what I've seen - those models were created in advance of the database itself to assist in clarifying the relationships... but my database already exists! Anyone have any suggestions for tools that would work, or methods I could employ to tease out a nice clean document describing my database structure? Thanks in advance!

    I downloaded the huge Windows 7 .iso file and burnt it to a DVD. I then used that DVD to install Windows 7 on my machine and then realized that I the .iso file was on the Vista operating system that I replaced with Windows 7 (didn't upgrade). So now I would like to get the .iso file back but with the same key, etc. How can I convert the DVD I burned back into an .ISO file?

  • What would be the best way to correlate logs and events on several hosts?

    - by user220746
    I'm trying to build a log correlation system on multiple hosts. SEC seems interesting but I don't know if it will cover my needs. How could I correlate system events, logs, network events, etc. on multiple hosts at the same time, in real time? Examples: If 5 failed logins happened on host A the last minute and if firewall B has denied lots of access on differents ports on A, then we assume there is a potential attack in progress on A. If the Apache service on host A didn't receive any request for the last N minutes and Apache service on host B did, then the load balancing could be faulty.

  • Best way to block a country by IP address?

    - by George Edison
    I have a website that needs to block a particular country based on IP address. I am more than aware that IP-based blocking is not a foolproof method for blocking visitors, but it is a necessary step in the right direction. Since I'm using PHP, what I would do is use a GeoIP database like geoplugin.net. However, I'm curious to know if there's a better way of doing this. The website is on a shared webserver (I don't have root access) and it is running Apache on centOS. I guess my question is "can an .htaccess file be configured to block by IP using an external source to lookup IP addresses."

  • Squid reverse proxy array - siblings not communicating with each other

    - by V. Romanov
    I want to set up 2 squid servers to act as reverse proxy and cache for a webserver on our intranet. The load balancing will be done with DNS round robin or just different mappings for different clients. The thing is, I want both servers to try and contact each other to see if they have the object required in cache before contacting the webserver for it (the network that servers the webserver is the bottleneck and I'm trying to eliminate it) Both squids are configured the same, here are the relevant config lines : acl dvr1_cache_it_best_tv_com dstdomain dvr1.cache.it.best-tv.com acl squid1_it_best_tv_com dstdomain squid1.it.best-tv.com acl squid2_it_best_tv_com dstdomain squid2.it.best-tv.com http_access allow dvr1_cache_it_best_tv_com http_access allow squid1_it_best_tv_com http_access allow squid2_it_best_tv_com http_access allow all http_port 8081 accel defaultsite=dvr1.cache.it.best-tv.com cache_peer dvr1.origin.it.best-tv.com parent 80 0 no-query originserver name=Proxy_dvr1_origin_it_best_tv_com cache_peer squid1.it.best-tv.com sibling 8081 3130 weight=10 name=Proxy_Squid1_it_best_tv_com cache_peer squid2.it.best-tv.com sibling 8081 3130 weight=10 name=Proxy_Squid2_it_best_tv_com cache_peer_access Proxy_dvr1_origin_it_best_tv_com allow dvr1_cache_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow squid1_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow squid2_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow dvr1_cache_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow squid1_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow squid2_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow dvr1_cache_it_best_tv_com just to make it clear - dvr1.cache is the alias for the proxy servers. dvr1.origin is the web server. Both servers work, both serve content and cache it and work fine. However, when I clear the cache on one server and then access it, it gets the content from the parent (DVR1_ORIGIN) instead of going to the sibling squid. What did I configure wrong? Or perhaps I don't understand the architecture correctly? I read the squid manuals but as far as I see i did it all by the book and yet it doesn't work right. Any help will be appreciated!
