  • free open-source linux screenshot & ocr tool

    - by Gryllida
    I'm looking for a tool which would be able to capture a screen region, pass it to OCR and put the result into clipboard. "import ppm:- | gocr -i - | xclip -selection c" works, but gocr is unreliable: simple text on a webpage has errors. It is a clear font but the OCR tool always misses "r" and replaces it with underscore. "import ppm:- | ocrad -i - | xclip -selection c" says "ocrad: maxval 255 in ppm "P6" file." tesseract needs an image file and does not accept piping input to it. xfce4-screenshooter does not do OCR. ABBYY Screenshot Reader is proprietary. tessnet2 is freeware running on a proprietary platform. Google Docs can OCR screenshots in a batch. But my data is confidential and better not put online. Graphical interface solutions would be acceptable for this question, too. There is a number of existing SuperUser questions about OCR. They fall in several categories. Questions just about OCR without the "screenshot taking" part.

  • So you're a new sysadmin...

    - by 80bower
    I've recently taken over management of a Windows 2003 Small Business server and network for a small, less than ten person company. I have some (antiquated) sysadmin experience, but I've little experience with Exchange. The documentation of the existing infrastructure leaves much to be desired, and I was wondering if there's any sort of "So you've just become sysadmin" guides that anyone could recommend.

  • How to send mail from ASP.NET with IIS6 SMTP in a dedicated server?

    - by Julio César
    Hi. I'm trying to configure a dedicated server that runs ASP.NET to send mail through the local IIS SMTP server but mail is getting stuck in the Queue folder and doesn't get delivered. I'm using this code in an .aspx page to test: <%@ Page Language="C#" AutoEventWireup="true" %> <% new System.Net.Mail.SmtpClient("localhost").Send("[email protected]", "[email protected]", "testing...", "Hello, world.com"); %> Then, I added the following to the Web.config file: <system.net> <mailSettings> <smtp> <network host="localhost"/> </smtp> </mailSettings> </system.net> In the IIS Manager I've changed the following in the properties of the "Default SMTP Virtual Server". General: [X] Enable Logging Access / Authentication: [X] Windows Integrated Authentication Access / Relay Restrictions: (o) Only the list below, Granted 127.0.0.1 Delivery / Advanced: Fully qualified domain name = thedomain.com Finally, I run the SMTPDiag.exe tool like this: C:\>smtpdiag.exe [email protected] [email protected] Searching for Exchange external DNS settings.

Thanks @mattlant This is a dedicated server that's why I'm installing the SMTP manually. EDIT: I use exchange so its a little different, but its called a smart host in exchange, but in plain SMTP service config i think its called something else. Cant remember exactly the setting name. Thank you for pointing me at the Smart host field. Mail is getting delivered now. In the Default SMTP Virtual Server properties, the Delivery tab, click Advanced and fill the "Smart host" field with the address that your provider gives you. In my case (GoDaddy) it was k2smtpout.secureserver.net. More info here: http://help.godaddy.com/article/1283

  • 5.5.0 smtp;554 transaction failed spam message not queued

    - by Miguel
    Some users are trying to send email to certain domains using Exchange Server 2003, but the message is always is rejected and the following message is shown: 5.5.0 smtp;554 Transaction Failed Spam Message not queued The IP is not in a black list (checked using http://whatismyipaddress.com/blacklist-check and is clean - not listed).

  • Who uses Zimbra Collaboration Suite and why?

    - by AlberT
    I am really curious about other people experiences and choices. After a long scouting, I found ZCS to be a really impressive solution, maybe the only real alternative to M$ Exchange. I'm very interested in opinions and case histories from users having already deployed Zimbra on their infrastructure or planning to do it. Both Community and Network edition cases are appreciated, pro and cons explained too :) Zimlets, addons, useful skins, Zimbra Desktop and other apps or mobile integration use case too of course.

  • Removing Windows 2003 Server and Domain from Network

    - by Mike Ruford
    I have a Windows-2003-Server with five computers (Windows XP) accessing it using a domain. I would like to remove the server and the domain and go straight to peer to peer (file sharing via a NAS). We are moving our email to an Exchange Hosting Provider. We no longer need people to log in from different computers and have their desktops available from any computer on the network (however, I do want to get those files off of this setup). Any suggestions?

  • After Effects Question

    - by Josh
    Question here, not sure if it's the correct stack exchange site, sorry if it isn't. I have an After Effects project for school, and I've created a movie using JPEG sequences (10 @ ~100-200mb/each ). I have the output setting on the composition set to 640x480. I resized each JPEG layer via the fit to comp tool, but when I export the movie as a Quicktime movie, it is 1.1 gig for ~35 seconds of movie at 30fps. What am I doing so horribly wrong here?

  • Guests can't access KVM host server by name although nslookup and dig returns correct record

    - by user190196
    So I have a KVM host that also runs an apache server with some yum repos. The VM guests are connected to the default virtual network, which is configured to offer DHCP and forwarding with NAT on virbr0 (192.168.12.1). The guests can successfully access the yum repos on the host by IP address, so for example curl 192.168.122.1/repo1 returns the content without problems. But I'd like to have the guests be able to reach the web server on the host by name rather IP address. I added the desired name record to the host's /etc/hosts file and libvirt's dnsmasq service seems to be serving that correctly to the guests since nslookup and dig successfully resolve the name on the guests: [root@localhost ~]# nslookup repo Server: 192.168.122.1 Address: 192.168.122.1#53 Name: repo Address: 192.168.122.1 [root@localhost ~]# dig repo ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6 <<>> repo ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55938 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;repo.

  • Moving Server to new Hardware - SBS 2008

    - by MikeT505
    Hi, We have very quickly out-grown our Small Business Server 2008 current hardware and have decided to purchase a complete new server. What is the best and easiest way to move the server to new hardware? It is one complete box, we do not have any SAN's or any complicated setup. We do have a couple of SQL databases running on the server and we also use Exchange. I'm sure there must be some easy way to move everything :-)

  • Remember login when connecting to another domain on Windows 2008 Sever

    - by lox
    I run Windows 2008 Server (x64) as a workstation and my computer is on one domain and my exchange server, shared folders and intranet is on another domain. Every time I connect to these eg. every time I open Outlook I am prompted to supply username and password in a "Connect to"-dialog and the "Remember password" option has no effect. What can I do to avoid this manual step every time?

  • Optical multicast

    - by Randomblue
    I have a 10G XPF+ optical cable with market updates from a stock exchange. This cable goes into a switch, which then multicasts every packet to a couple of computers. The problem with using a switch for multicast is that there is latency overhead, even with a pass-through switch (~200ns). Are there "optical" solutions (I'm thinking of a beam splitter of some sort) which would allow for close to zero latency 10G multicast?

  • Why do Ping and Dig provide different IP address than nslookup?

    - by user1032531
    When pinging my domain name which points to my home public IP from two different servers on my LAN, it shows them pinging different IP. Further investigation shows dig and nslookup providing different results. See below. A little history. My IP used to be 11.22.33.444 and is hosted by Comcast. I changed routers, and it somehow got changed to 55.66.77.888. I've since updated my 1and1 domain name to point to the 55.66.77.888. desktop is a basic server, runs the web server, and connects wirelessly to my LAN. laptop is a GUI and connected via CAT5. Both operate Centos6.4. My old router was a D-Link, and used their "Virtual Server" feature to pass port 80 to desktop. My new router is a Linksys, and I use their "Port Forwarding" feature to pass port 80 to desktop (however, I haven't gotten this part working yet). What is going on??? Why the different IPs? Obviously, it most somehow be stored on the server, but why does the actual machine even know the public IP since it is on a LAN? How do I purge the old IP?

  • Is there a Kerberos testing tool?

    - by ixe013
    I often use openssl s_client to test and debug SSL connections (to LDAPS or HTTPS services). It allows me to isolate the problem down to SSL, without anything getting in the way. I know about klist that allows me to purge the ticket cache. Is there tool that would allow me to ask a Kerberos ticket for a given server, not event sending it ? Just enough to see the whole Kerberos exchange in Wireshark for example ?

  • Virtual Machine with Bridged Adapter to Centos not accepting ssh from host machine [migrated]

    My company is switching email servers and I wanted more input from people who know more about IT. We are a small company that would only have 7-8 users. We use MS outlook and need a compatible solution. Im not sure what server we are switching from but i have been looking at google apps. Exchange is a little more expensive but we are considering that as well. Any suggestions/ recommendations regarding these two or others????

  • Microphones not working on Apple macbook Air 1,1 (Early 2008) under Linux

    - by jj_p
    I'm running Linux on an mba. I can't make the microphones (neither external nor internal) work. I test using alsamixer and arecord -d 5 test-mic.waw together with aplay test-mic.waw It seems there is a problem with kernel trying to decipher Apple (intentionally) corrupted 'bios', in particular the mic pins are wrongly assigned. As far as we are concerned here, is there any difference between using EFI and BIOS-compatibility mode? (see https://wiki.archlinux.org/index.php/MacBook where they claim to have everything working out of the box on mba1,1) A nice proposal would be to compile the latest Linux kernel and run hda-jack-retask to find the right configuration (in the case of Realtek codec, the missing things I'm supposed to check are either some vendor-specific COEF verbs, EAPD or GPIO setup.), and then come up with a kernel patch to address the issue. Since I'm not that familiar with this last part of the story, can anyone help me through this process? Some useful data: The output from alsa script run as root http://www.alsa-project.org/db/?f=adae8ebee1007043fe83414ac4972319e02255fa The command hda-jack-sense-test -a (with external mic in) Pin 0x14 (Internal Speaker): present = No Pin 0x15 (Green HP Out): present = Yes Pin 0x16 (Not connected): present = No Pin 0x17 (Not connected): present = No Pin 0x18 (Not connected): present = No Pin 0x19 (Not connected): present = No Pin 0x1a (Not connected): present = No Pin 0x1b (Not connected): present = No Pin 0x1c (Not connected): present = No Pin 0x1d (Not connected): present = No Pin 0x1e (Not connected): present = No Pin 0x1f (Not connected): present = No Most likely the chip is Realtek ALC885 (compare also ALC889A) http://guide-images.ifixit.net/igi/bBTSqaeK5JpQ1AWe.large , although at the moment alsa reads it as ALC889A Takashi Iwai's tutorial https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt Some people researched the original files from a running OS X installation on this same model (I think the relevant files are AppleHDA.kext/Contents/MacOS/AppleHDA AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.p????list AppleHDA.kext/Contents/Resources/layout12.xml.zlib AppleHDA.kext/Contents/Resources/Platforms.xml.zlib) http://www.insanelymac.com/forum/topic/220090-alc889a-pin-configuration/#entry1554954 Datasheet http://www.realtek.info/pdf/ALC885_1-1.pdf (from the same Realtek, one can also try to download Linux driver, but this is just taken from ALSA project, as stated in the readme file.) Compare with this Arch guy http://www.alsa-project.org/db/?f=3ca8243c0626844f0264a3faad0aa72018bc14f4 Here for the first time support to audio (except mics) for mba1,2 (which is morally the same as 1,1) is patched into the kernel http://www.alsa-project.org/pipermail/alsa-devel/2010-February/025511.html The same jack supposedly works both for HP and ext MIC, I think it's called TRRS, and it's the same as the one used e.g. for iphones This guy might have done a similar job, though to a more recent version and for sound globally, not just mics: http://blogs.aerys.in/jeanmarc-leroux/2013/09/15/fixing-2013-macbook-air-ubuntu-sound-issue/ (this is mirror to http://unix.stackexchange.com/questions/73044/microphones-not-working-on-apple-macbook-air-1-1-early-2008-under-linux )

  • Windows 8.1 Insufficient storage available to create shadow copy

    - by Bob.at.SBS
    [Note: After I entered the problem statement, I found this question, which is apparently the same problem. Maybe one of us will get a good answer...] I have used the "Windows 7 File Recovery" tool under Windows 8 to create system image backups to an external USB hard drive. I built a new Windows 8.1 machine, and I want to create my first system image backup of that machine to the same USB hard drive. The "Windows 7 File Recovery" tool is gone in Windows 8.1, but wbAdmin is alive and well: wbAdmin start backup -backupTarget:\\?\Volume{2a2b...994f} -allCritical -quiet fails with this text displayed: wbadmin 1.0 - Backup command-line tool (C) Copyright 2013 Microsoft Corporation.

  • Active Directory: delete vs. disable departed employees

    - by Matt Rogish
    When an employee leaves your organization, do you delete or disable their Active Directory account? Our SOP is to disable, export/purge the Exchange mailbox, and then after "some time" has elapsed (usually quarterly), delete the account. Is there any need for that delay? After exporting and purging their mailbox, why shouldn't I delete the account right then and there?
