  • Network communication across two private network

    - by Sethu
    Hi All, I am trying to implement a peer to peer communication .. I use sockets for communication between them. I want to know if there are any ways i can use the same sort of communication when the two peers are behind two private Networks (They dont know each others public ip address.) I can think of a shared buffer in a well known location as a means of communication. But is there some other way to get this done?

  • Apple push notifications - firewall?

    - by fede
    I've read that to receive push notifications over Wifi the firewall must allow TCP traffic over port 5223. However, the network administrator tells me he needs the IP addres of the server. Would it be gateway.sandbox.push.apple.com? Thanks!

  • Bash - read as a fallback to $@

    - by user137369
    I have a working bash script (working on OSX) that takes files and directories as input and does something like for inputFile in $@ do [someStuff] done but I want to provide a “fallback”, meaning, if the script is started with no arguments (double-clicked, for example), it can take input at that time, by letting the user drop the files directly on the terminal (possibly through read but not mandatory, I'm open to better/different solutions). I'm guessing I should use some kind of if statement, but I'm not sure how. I'd like to not have to essentially duplicate the script's size by two by repeating [someStuff] for each case. Thank you.

  • Help changing MAC address in Windows 7 [closed]

    - by Niphoet
    Possible Duplicate: Change MAC Address I need to change the MAC address of my wireless adapter in Windows 7 (Ultimate RTM). I used to do this in XP both directly in the registry editor and with a .REG file I wrote. I have used each of these methods in Windows 7, as well as a few tools I found that are supposed to do this. Every time I change it, I disable and re-enable the network adapter in control panel, but upon running ipconfig /all it still shows my old MAC address. Any help? By the way, I do have Administrative Rights and UAC turned off.

  • Certificate Template Missing from "Certificate Template to Issue"

    - by Adam Robinson
    I'm having a problem similar to that posted in this question: Missing Certificate template From certificate to issue The short version is that I've created a duplicate certificate template and I'm trying to add it to my domain CA so that I can issue certificates with it. However, when I go into the Certification Authority MMC and go to "Certificate Templates - New - Certificate Template To Issue", my template is missing (along with quite a number of other templates that are present in the domain). Unlike the previous question, however, my CA is running on Server 2008 R2 Enterprise. Our organization has a single DC and a single CA, so I'm not seeing where there could be propagation delay. Any ideas how to get my template to show so that I can issue certificates?

  • Looking for Inneroffice Access Tool, Workstation to Workstation

    - by nicorellius
    This may be a simple question to answer, and I apologize if it's a duplicate. I looked through the suggestions and nothing jumped out at me as the right answer, so here goes: My office has several workstations, Macs and Windows boxes. We do have a firewall and a VPN solution, so getting in to the network from outside is easy. Likewise, we use GoToMeeting for demos and when we help our customers with their issues. But we have one workstation that has certain testing tools on it, and instead of walking across the office to this machine, I'd like to access it from my desk (and monitor it). I will need to open a command line and run commands. I could start a GoToMeeting and do it this way, but that seems overkill and clunky. Is there a simpler tool that allows pseudo-remote access within the same office/network for this kind of access?

  • Is there an unintrusive antivirus program that I can ask to scan object on demand only? [closed]

    - by Faken
    Possible Duplicate: Recommended offline on-demand virus scanners I'm looking for an unintrusive antivirus program that I can get to run scans on suspicious objects on demand and only on demand. Most other antivirus programs install many layers of protection and things running in the background and preform regular updates and system scans at inconvenient times. I want an antivirus program that I can simply right click and object and select "scan for viruses" and nothing more. Is there a reliable antivirus program out there that offers this and only this without the automatic updates, background processes, and intrusive automatic system scans? Note: this is for Windows.

  • How do I tell logrotate what files to rotate with cron?

    - by cwd
    On my webserver I have this file: /etc/logrotate.d/apache2 I know it is logrotating /var/log/apache2/.log, but if I want to add things that are in /usr/home/www/site1/logs/.log do I just duplicate everything below and stick that line in there? Each time I add a new site do I need to manually add lines to this file? Or what is the most professional way to do this? /var/log/apache2/*.log { weekly missingok rotate 52 compress delaycompress notifempty create 640 root adm sharedscripts postrotate if [ -f "`. /etc/apache2/envvars ; echo ${APACHE_PID_FILE:-/var/run/apache2.pid}`" ]; then /etc/init.d/apache2 reload /dev/null fi endscript }

  • Adding multiple gradients to object in Adobe Illustrator

    - by Vass
    Hi, I have an object which is a path (a nose to be specific). Now I want both a linear gradient and a radial gradient to be added to the object. So these must be separate gradient objects I guess, and I can't find a way to add multiple separate gradients to a complete path so do I duplicate the object and then apply a new gradient to each object? And what would the layer transparency features look like? Would the 'normal' overlay of the layers work? I am afraid of multiple shadows creating double dark regions, but maybe that is as its supposed to be if you think in terms of classical art and draw shadows in terms of each light obstruction.

  • Nginx password protect one domain and avoid config duplication

    - by gansbrest
    I got 2 domains dev.domain.com and beta.domain.com. At the moment I have one server section (default) with a bunch of specific locations and rules. Now I need to password protect beta.domain.com. Is there a way to do this without creating additional server section and essentially duplicating all my location and other rules? Generally I would like to know how other people manage complex nginx configurations. Do they just copy sections (duplicate) or include common rules somehow?

  • Why won't Outlook sync with Google Calendar?

    - by mipadi
    A colleague of mine is having problems with Outlook and Google Calendar Sync. He got a new machine and set up Outlook 2007 on that machine. He also installed Google Calendar Sync. However, when he synced Outlook with Google Calendar, he got a number of duplicate entries in Outlook's calendar. We tried deleting all entries in the Outlook calendar and doing a 1-way sync from Google Calendar to Outlook, but the duplicated entries appeared again. We ultimately removed the duplicated entries manually, but we experienced problems pushing the changes back to Google Calendar, so we deleted the calendar in Google Calendar and tried to sync again (using a 1-way sync from Outlook to Google). Now Google Calendar Sync says that it is synchronizing, but no entries appear in the Google Calendar calendar. What could the problem be?

  • Authenticating Mountain Lion over Ubuntu 12 LDAP [closed]

    - by Sam Hammamy
    Possible Duplicate: Ubuntu OpenLDAP and Mac OS X Roaming Profiles I've installed slapd on Ubuntu 12 after a long long day of trial and error. I've added the apple.ldif schema, and the samba.ldif schema, plus a test user. Last week, I had installed slapd on Ubuntu 11, and was able to authenticate against it from OS X Lion after finding the following blog post: Fixing OpenLDAP Authentication on OS X Lion This suggests running the following commands to fix the authentication problem /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string CRAM-MD5" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string NTLM" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string GSSAPI" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist However, I ran these commands on OS X Mountain Lion, and I am still unable to authenticate. I can't even use the Directory Editor app to examine the AD. I am however able to bind to the server via python-ldap's ldap.simple_bind_s('cn=admin,dc=foo,dc=net,'secret'). The error I am getting when trying to use Director Editor is Error Code (5000)

  • Everything Windows Explorer does hangs up t some time or another

    - by William Barnes
    Yes this is a duplicate of something I have tried to ask in the past. I think I am posting wrong since my first question was deleted OK I ran SCANNOW nd it came back with no problems. I booted in Safe mode and windows evplorer worked OK. I am not sure what that proves. I also ran AUTRUNS and disabled everything that you said, but it still dies. I read someplace that it could be a service program, but I can't find that link anymore. Something about shutting off all non-windows SP's and then start adding back SP's until it quits. The problem is that sometimes it will work, but most of the time it does not. Makes saving or retrieving anything impossible. SAVEAS hangs up, my Garmin Map updater hangs up etc.. I was having this problem before installing Garmin so I am reasonably sure it is not the problem HELP PLEASE, I don't have many brain cells left and can't afford to lose more.

  • proxy/vpn by dns entry

    - by rcourtna
    I've been using a service by unblock-us.com, which provides a proxy to Canadians/others allowing access to services that are locked down to only US ip addresses. This is easy enough to achieve by setting up a reverse proxy (eg: squid) on a US-hosted server, and then configuring your browser or OS to use that proxy. However, there is something that unblock-us does that I'm not sure how to duplicate. Rather than configuring your OS to use them as a proxy, you can simply change the DNS Server settings on your router to point to their addresses. Any requests to services they support are automatically proxied. The advantage to this is that you don't have to set up every computer in your house, and it "just works" with clients like ps3, xbox, android, etc. Disadvantage is you really don't have control over what gets proxied, as well as there are privacy concerns I suppose. How can I achieve this same functionality on my own us-based slice?

  • How to Remove a VM From Hyper-V Without Deleting the Configuration File?

    - by Steven Murawski
    I'm in the process of moving a number of virtual machines that are homed on shared storage (a file share, though shared cluster disk would work as well) to a new VM host with access to the same shared storage. The new host is a different build version (moving from Windows Server 2012 Beta to Windows Server 2012 RC - though this same process could be used with migrations of Windows Server 2008/2008 R2 to Windows Server 2012 as well), so I cannot migrate the machine with inbox tooling. I need to remove the VM from management of the source Hyper-V host in order to import the VM to the new Hyper-V host. I want to retain the configuration file, so I can import the VM as it stands and not need to reconfigure it. The VHD files are rather large and they are staying on the same file share, so I'd rather not duplicate them during the move process.

  • OS X Headphone jack issue [closed]

    Possible Duplicate: Optical Audio out stuck on on a MacBook When I plug my headphones into my iMac (27-inch, Mid 2011; OSX 10.8.1) and try to adjust the volume, the volume popup shows a greyed out speaker and there's a circle with a line through it signalling that it isn't working. I've tried the headphones with my iPhone, other iMacs etc and they're fine. This is incredibly frustrating. Other headphones don't generally work either. In Sound preferences the headphones are being listed as "Optical digital-out port" which is incorrect and would explain the problem, but doesn't help me fix it. Any ideas?

  • How does the Twitter rate limit API work with multiple accounts?

    - by dfrankow
    I know there's a Rest API to check the Twitter rate limit. To summarize policy: 150 for an IP, and 150 per non-whitelisted account except for searches (which are IP only). However, my app is using Twython, authenticated, but the limit seems to decrease for both my accounts as I use it. Example: No authentication: $ wget http://api.twitter.com/1/account/rate_limit_status.xml -O - <?xml version="1.0" encoding="UTF-8"?> <hash> <hourly-limit type="integer">150</hourly-limit> <reset-time-in-seconds type="integer">1266968961</reset-time-in-seconds> <reset-time type="datetime">2010-02-23T23:49:21+00:00</reset-time> <remaining-hits type="integer">134</remaining-hits> </hash> Authentication with account #1: $ wget --user b... --password=youwish http://api.twitter.com/1/account/rate_limit_status.xml -O - <?xml version="1.0" encoding="UTF-8"?> <hash> <reset-time-in-seconds type="integer">1266968961</reset-time-in-seconds> <reset-time type="datetime">2010-02-23T23:49:21+00:00</reset-time> <remaining-hits type="integer">134</remaining-hits> <hourly-limit type="integer">150</hourly-limit> </hash> Authentication with account #2: $ wget --user d... --password=youwish http://api.twitter.com/1/account/rate_limit_status.xml -O - <?xml version="1.0" encoding="UTF-8"?> <hash> <reset-time type="datetime">2010-02-23T23:49:21+00:00</reset-time> <remaining-hits type="integer">134</remaining-hits> <hourly-limit type="integer">150</hourly-limit> <reset-time-in-seconds type="integer">1266968961</reset-time-in-seconds> </hash> You see how both accounts seem to have exactly the same rate limit info (134/150)? I only used one account in my app, so why do both accounts show decrease?

  • Log centralization, display, transport and aggregation at scale v2

    - by Eric DANNIELOU
    This is a duplicate question of Log transport and aggregation at scale and http://stackoverflow.com/questions/1737693/whats-the-best-practice-for-centralised-logging, but the answers might differ now : The softwares described in 2009 may have changed since (for example Octopussy evolved from version 0.9 to 1.0.5). Rsyslog has become the default on most linux distro. Requirements have changed (security, software configuration management, ...). I'd like to ask the following questions : How do you centralize, display and archive system logs? How would you like to do it now if you had to? Most linux distro use rsyslog nowadays, which can provide reliable log transport. But some older unices, network devices and maybe windows box still use old udp rfc-style transport. How did you manage to get reliable transport? Storing logs for a few months can represent a huge amount of disk space. How do you store them? rdbms? Compressed and encrypted text files?
