  • How do I reattach to Ubuntu Server's 'do-release-upgrade' process?

    - by Alex Leach
    I accidentally pressed Ctrl+C during Ubuntu Server's do-release-upgrade process. I'd dropped to a shell to compare a .conf file in /etc/. When I pressed Ctrl-C, it asked whether I wanted to try to reattach to the upgrade process, but it failed to do so. So I quit, and now there's a hanging dpkg process which is holding onto the apt lock. This is a virtualised server with no GUI frontend... Is it possible to recover the upgrade process, or do I have to kill the dpkg process and start again? UPDATE:- AFAICT, there was no way to reattach to the upgrade process. However, it wasn't a disaster at all. I killed the hanging dpkg process, and then ran dpkg --configure -a. This walks you through reconfiguring all packages already installed on the system, tidying up any problems whilst it does so. After that, I used aptitude to upgrade the remaining packages, which had already been downloaded, but hadn't been installed or configured.

  • What settings to use for fastest reloading of a MySQL backup?

    - by Alex R
    I have a MySQL database which dumps to a 3.5 GB backup (mysqldump) in about 10 minutes. But reloading this backup on a standby / test server takes upwards of 12 hours. What are some settings that would maximize reloading performance? The most promising appear to be innodb_buffer_pool_size, innodb_additional_mem_pool_size, and innodb_log_buffer_size... but I'm reaching the limits of my trial-and-error approach. Which of these settings "should" be the most important? Through trial-and-error I was not able to get more than 70% CPU utilization and 63% memory utilization. I'd like both at 100% during a reload. All tables are InnoDB.

  • Synchronising a remote folder with a local one.

    - by Workshop Alex
    I am using a network disk (that's connected to my router by USB) to store several data files. A simple .NET application that I've created is supposed to read and modify these data files. However, some security issues are preventing this application to access these files directly. (Actually, these have been built-in to my application on purpose since it's not going to support NAS disks.) Since this disk is shared with several computers, I just want to have a simple synchronisation method, which will copy the files to a local folder where3 my application can access them. And, once modified, it should send back the modified files to the NAS disk again. I have two options: 1) Build a second application to do my own synchronisation. 2) Find some build-in function inside Windows 7 Ultimate which can do this for me. Option 2 is preferred. Option 1 is something I can do easily, if need be. I don't need third-party tools. (Still, feel free to add some references to good tools, although I won't accept them as answers.) Basically, is this possible with Windows 7 and if so, how?

  • Overscan in Catalyst Control Center

    - by alex
    I've connected my PC to my TV via HDMI (I've also tried using DVI). Whatever the resolution (anything from 800 x 600 to 1080p), the image displayed on the TV does not fill the entire screen surface; there's a black border on the edge of the image. This happens in both Vista and Windows 7. After a bit of searching I came to the conclusion it's got something to do with overscan done by the graphics card (ATI 3200HD). It's definitely not the TV because on my old PC there were no such problems. I've searched for the option in Catalyst Control Center 9.9 but it's not available for the TV; if I connect a normal LCD display, the option is there, but only for the LCD screen. If I choose Configure for my TV, where the overscan option should be, it takes me to the Welcome tab in CCC. How can I make the image fill the entire screen? How can I enable/disable overscan for my TV?

  • Missing management console for Symantec Antivirus, Corporate Edition

    - by Alex C.
    I work for a small (80 employees) non-profit organization. We have a Windows network with a domain. The file server is running Server 2003. A vendor recently installed Symantec Antivirus, Corporate Edition, ver. 10.1.8.8000. It used to be the case that when I logged in to the file server as administrator, I would see an icon on the desktop that took me to the management console for the antivirus software. I could check logs, statuses of client machines, set policies, etc. That icon is now missing, and I can't find anything relevant under the "Start" menu. There is an entry for Symantec Antivirus, but that only gives me the panel for the client process, not the overall management console for the whole network. I don't want to call the vendor back to fix this (I'm baffled how we lost the icon in the first place). Can someone offer some guidance?

  • My DNS works! But, what is the simplest way to add something to it?

    - by Alex
    This is my current DNS example.com.db zone file. I followed a tutorial. It works, because when I point to this DNS from another server via resolve.conf, it will actually forward me to the right IP when I do "ping example.com". ; ; BIND data file for example.com ; $TTL 604800 @ IN SOA example.com. info.example.com. ( 2007011501 ; Serial 7200 ; Refresh 120 ; Retry 2419200 ; Expire 604800) ; Default TTL ; @ IN NS ns1.example.com. @ IN NS ns2.example.com. example.com. IN MX 10 mail.example.com. example.com. IN A 192.168.254.1 www IN CNAME example.com. mail IN A 192.168.254.1 ftp IN CNAME example.com. example.com. IN TXT "v=spf1 ip4:192.168.254.1 a mx ~all" mail IN TXT "v=spf1 a -all" Right now, ping example.com....goes to 192.168.254.1. That's great!!! it works! My question is--how can I add something do this file so that when my other servers: ping dbserver1....goes to 44.245.66.222 ping cacheserver1 ....goes to 38.221.44.555 I want to use it like a universal hosts file for my machines.

  • Work from home on an iPad?

    - by Alex Basson
    The situation: My wife has a 13" MacBook Pro that she uses for email, Facebook, web surfing, and working from home. I'm about to buy us our first iPad. My wife's brother's computer just went belly-up, and she's contemplating giving him her MacBook and just using the iPad. The question is whether or not this is possible or realistic. Obviously, the iPad is well-suited for the email/web/Facebook tasks, but the working-from-home thing is an absolute must -- if the iPad can't handle that, it's a deal-breaker. For my wife, working from home means two things: Accessing her workplace computer's Windows Vista desktop, which she currently does via Remote Desktop. Editing Office documents locally, which she currently syncs via Dropbox. Being able to edit documents locally is important, because sometimes she will download documents and edit them when she doesn't have network access (e.g. on the subway). I'm more than happy to get a keyboard dock for her, so typing won't be an issue. Are there any iPad apps she can use to access her work computer and edit her work files? Thanks for any suggestions!

  • Redirect everything except the homepage

    - by Alex
    Is there a way in nginx to redirect everything from domain1.com to domain2.com, except for the homepage? Right now I have: server { listen 80; server_name www.domain1.com domain1.com; rewrite ^ http://domain2.com$uri permanent; } This works, except that I'd like http://domain1.com (without any additional path) to be left alone and not redirected. Basically, I need to redirect everything, to avoid broken links, but I want to use the homepage of domain1 to serve a static file.

  • Killing CLOSE_WAIT sockets without killing parent process on Linux

    - by Alex Neth
    Tomcat is leaving me with CLOSE_WAIT sockets which ultimately saturate the maximum number of connections. I've tried many methods in my client and server code to get rid of these to no avail, including closing connections, calling System.gc(), etc. Now I'm trying to find a way to simply time these out quickly in the OS. I've got conntrack working, but am not sure how to use that to kill these connections. I've also set /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_timeout_close_wait to 1, which of course is too low but the connections persist. Is there a way to kill these zombie sockets? Running Ubuntu.

  • NFSv4 - ACLs not working

    - by alex
    I've setup an NFSv4 server (Debian) and client (Ubuntu/Mythbuntu). It seems that uid username mapping is working nicely out-of-the-box (I get correct usernames on ls -l if the usernames match between the two boxes, even if the uids don't), but ACLs are not working. I've installed nfs4-acl-tools and I can read the ACLs correctly on the client, but they don't get applied. What needs to be done for ACLs to work? To clarify; username mapping works for regular permissions. ACLs are applied using uid/gid (I can even set ACLs by uid and they work).

  • Unable to sync iPod Touch with my PC

    - by alex
    I'm trying to sync a first gen iPod Touch to my PC running Windows 7 64 bit. The problem is that whenever I connect the iPod, iTunes completely freezes (if I start iTunes after connecting the iPod it will simply hang until it's physically disconnected from the PC). I reinstalled iTunes thinking that it had been corrupted, but without any luck. I've had this problem with all the latest versions of iTunes. I've also tried using MediaMonkey and DoubleTwist. None of these apps see the iPod as being connected; DoubleTwist also freezes, just like iTunes. The really strange thing is that I was able to sync the iPod with this PC a while back, but I now seem to have lost that ability. I don't know what changed. Windows detects the device every time it's plugged in (I can see it in Device Manager and I can browse all photos on iPod as if it were a camera). Also, I can sync it to iTunes on Mac OS X without any major problems.

  • My iPhone is stuck at screen with USB cable and iTunes logo

    - by alex
    I just tried updating the iPhone's firmware, and things went haywire. iTunes informed the update had failed and linked me to this page. The iPhone is stuck on the image from the top of that page. I held down the sleep and home buttons until it turned off and turned it back on, and then went through the iPhone's 'restore' mode. It then error'd again and I'm stuck back with the logos on the iPhone. Does anyone know how to fix this? Thanks

  • How can Facebook's session get mixed up because of NAT and/or Proxy

    - by Alex
    Have received some reports from a customer (a very large company) they reported issues from clients who are using Facebook. These clients claim that once in a while when they log in to Facebook they end up in someone else's session. I know that network is NATed then Proxied before getting to Facebook.com. Although I'm not able to explain how this issue can occur. Is it possible that the Proxy is not sending the right session back to the clients? How can they end up with someone else's session since Facebook is cookie based session?? Anyone seen this before?

  • Seriousness of a "Smart" disk error. How long will it last?

    - by Workshop Alex
    I have an 1 TB data disk and the bios and Windows are reporting a "Smart" error. At least, I get a Smart event but it doesn't indicate how serious the failure could be. My system is about 6 months old, including the disk so the warranty will cover the damage. Unfortunately, I lack a second disk of 1 TB in size which I can use to make a full backup. The most important data on this disk is safe, but there's a lot of work data which can be regenerated but this would cost a lot of time. So I ordered an USB disk of 1 TB which will arrive in three days. By then I can make a full backup of the data and afterwards, it can crash. But will the disk live that long? (Well, I won't use the PC as long as I can't make a backup.) How serious is such a Smart event? I know it's serious enough to have it replaced, but will it live for another week or could it die any moment?Update: I purchased an 1 TB external disk and spent most of the day making a backup of the 1 TB disk. It survived that. I then received a new disk, since it was still under warranty and replaced the hard disk. Then I had to spend most of a day again to put back the backup. I need to send back the faulty disk and now have an additional external disk, which could always be practical. :-) The Smart Error report did not cause any failures on the original disk. I won't advise to ignore these warnings, but the disk still has enough life in it to last a few more days. (Just make sure you have a good back-up.) And oh, the horror of having to make a complete backup such a huge disk. :-) If your data is important, make sure you have something that supports incremental backups and lots of space. (In my case, the data wasn't very important, just practical to have on-disk together.)

  • Serial converter - cat /dev/ttyUSB0 hangs on open

    - by Alex
    I am using Ubuntu 11.04 and attached a Garmin data cable. The device gets recognized [17718.502138] USB Serial support registered for pl2303 [17718.502181] pl2303 2-1:1.0: pl2303 converter detected [17718.513416] usb 2-1: pl2303 converter now attached to ttyUSB0 [17718.513443] usbcore: registered new interface driver pl2303 [17718.513446] pl2303: Prolific PL2303 USB to serial adaptor driver ... but when I do a strace cat /dev/ttyUSB0 it hangs on the open part and does not continue any more open("/dev/ttyUSB0", O_RDONLY|O_LARGEFILEC If I do the same on Ubuntu 12.04 it stops on fread(" ... ") which is okay, as there is currently no data comming in at this port. I am not sure if it is just a different configuration of the system or an driver related problem. How can I track this down further? Unfortunately I can not update the old Ubuntu 11.04 system for different reasons at the moment.

  • VPS to replace MobileMe or Google Apps.

    - by Alex
    All, Yes, this has been touched on in other questions, but I can't find something similar enough. I currently have Google Apps hosting personal email, calendars, contacts, etc. I do like the other google services, but they're outside of Apps. One of the little google irritations that I have to maintain a separate account for Picassa, etc. So, I'm thinking about moving myself away from Google, but purely for personal, privacy type issues. Do I really like the ads, the email snooping, etc? I've had, and liked MobileMe, back when it was iTools, and then .Mac, but it doesn't offer that much really. How easily can I replicate it all on a VPS? I don't want to host it myself at home, I'd lose all the wonderful datacenter goodness. THis isn't about personal geekery in my own basement, just about taking a little control back from Google. So, email is fine running an IMAP server, a nice front-end, etc. What about Calendars and Contacts? And, how easily can it be setup to sync to the desktop and iPhone? Thanks.

  • Regarding AD Domain controllers and remote branch offices

    - by Alex
    We have central HQ building and a lot of small branch offices connecting via VPN and want to implement AD (If you can believe we still haven't). We want everyone to log in using domain accounts and be policed centrally. We are OK with having a RODC in a branch office with like 10 computers. But we have these small branches with two to four PCs only. Some of these branches connect to HQ via IPSec site-to-site VPN, some via remote access (client-based) VPN. So there is no problem with ones that have local RODC or connecting to HQ DCs via VPN router. But how about small branches? We don't really want to set up a machine there, neither we want to invest into Windows Server licenses or fancy network equipment. Also, the problem is that we cannot access HQ DCs via VPN because we are not logged in and connected to HQ internal network yet, so DCs aren't reachable. What is typically done in that situation if it is needed to have central management over policies on those PCs? Or is it better to let 'em loose and use local policies and accounts in this situation?

  • MS Licensing - 3 windows machines, 30 users, how many CALs required?

    - by alex
    I'm in the middle of upgrading, and purchasing licensing for 3 of our Servers. One will be a Windows Server 2008 machine, running SQL Server 2008. The other two machines will be domain controllers, both running Windows 2003. Our organisation has 30 Users. I understand (through our reseller) that a Windows 2008 licence gives "downgrade" rights to use 2003. Realistically, for the above setup of 3 machines, will I just need one set of 30 CALs for 2008?

  • "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.).

  • Suggested benchmark for testing CPU footprint of antivirus software

    - by Alex Chernavsky
    Our organization is currently running Symantec Corporate Antivirus, which is rumored to be a big resource hog. I know that we do have a lot of older machines that are running slow. Our PCs are all running Windows XP Pro and are used only for business applications (mostly Microsoft Office), e-mail, and web surfing. They're not used for gaming (one would hope not, anyway). I'd like to take one of the old PCs and do a speed benchmark test while it's running Symantec AV, then another test with no antivirus, and a third test with ESET NOD32. As I said, I don't care much about graphics performance. What would be an appropriate benchmarking program program to use? Freeware is best, of course. Thank you for considering my question.
