• How do you change your Airport or Ethernet MAC address in Mac OS X 10.6?

  - by Dave Gallagher

  I have a MacBook Pro and would like to set a custom MAC address for either my Airport WiFi card, or Ethernet port. In older versions of Mac OS X, you could do it like this: $ sudo ifconfig en0 ether 00:11:22:33:44:55 // Ethernet $ sudo ifconfig en1 lladdr AA:BB:CC:DD:EE:FF // Airport For it to work on Airport, you'd have to power it on (e.g. $ sudo ifconfig en1 up), ensure it's not connected to any wireless network, and execute the command. I'm aware such a change won't propagate across reboots. Unfortunately, this doesn't work on Mac OS X 10.6.6 anymore. Apple appears to have removed the functionality (the command fails silently). Does anyone have any idea how to do it? Thanks for any help you can offer! :)

• Help importing video from old Sony digital tape HandyCam

  - by thatryan

  Some friends gave me their old HandyCam and a bunch of tapes asking me to put them on a DVD. The model is Sony DCR-TVR103 and it records onto Hi8 digital tapes. It has a firewire port also. I am trying to use import function in iMovie on OS X 10.6. Every import though the video is super fast, like playing in fast forward. Ever seen anything like this? How can I import this video? Thank you.

• Monitor for HD video editing

  - by Kato

  I have been researching for days and nights on a good monitor to buy for a Mac Pro with an ATI Radeon 2600 XT (256mb). It will be used extensively for HD video editing (1080p) and photo editing, and likely also digital/3D animation next year(a lot of FCP + CS4). I am a student, so money is a little bit of an issue, but I want something that I'll be able to use semi-professionally after I'm done school, and am willing to finance something if it is worth the cost. I'm HOPING for something under $1000 though. The IPS Ultrasharps from Dell seem to be getting good reviews from other video editors. Accurate colour correction is a concern for me (hopefully something that covers Adobe spectrum), as well as a decent response time, HD resolutions, and DVI port. Also something with good gradient/definition in black areas, as this is difficult for editing on most LCDs. 1X1 pixel, brightness, good DVD playback etc. Hopefully this is not impossible to find for under $2000!

• Ngnix as reverse proxy for Apache name-based vhosts

  - by Ben Carleton

  I am running several websites on Apache currently utilizing name-based vhosts. All of the sites are on the same server. I would like to add Ngnix on a new server to sit in front of Apache as a caching reverse proxy. What is the best way to handle the multiple name-based vhosts? Should I simply have Nginx handle the names and run each Apache vhost on a separate port? Or is there a way to just have Nginx pass the hostname to Apache and have apache take care of the domain names?

• VMXNET3 nic loses the ability to update ARP table after N hours

  - by Peter

  I have a fedora 18 VM that stops updating the arp table on eth1 after running for a number of hours to days. There are other VMs on the same hypervisor that can access all of the same networks without issue. A tcpdump of the offending NIC shows only ARP broadcasts but no responses. None of the other VMs on the vDS see the ARP broadcasts from the offending NIC. The only way I can currently solve the problem is to reboot the VM and then everything works for a while. I've tried changing the port on the vDS and even flipping the network configurations after I lose eth1's ARP table, but the ARP problem follows eth1 but I can access the machines that were originally on eth1. If I statically add the arp entries for machines on the same subnet I have no problems with connectivity. The Hypervisor is an HP BL49X series with flex-10 network modules. Has anyone seen anything like this before?

• How to disable passive mode in linux ftp command

  - by nute

  I am using the "ftp" command of linux to send data to a 3rd party provider. This company states that we need to "Disable passive mode in your FTP client", and I confirm it doesn't work in passive mode. However, when I googled the linux command, I see that the "-p" flag is "the default now for all clients (ftp and pftp) due to security concerns using the PORT transfer mode. The flag is kept for compatibility only and has no effect anymore." How do I disable passive mode then? And, is it that bad?

• Windows 7 - swap file on a USB disk? [closed]

  - by Sara Cohen

  Possible Duplicate: How to move the page file to another physical disk location Windows 7 I was given temporarily a PC, running Windows 7 Ultimate. The problem is it's hard drive is full, there are like 250 MB free. The swap file is set to none. It has 4 GB RAM. When I load a few tabs in Chrome or IE and start a game it runs out of memory. I already emptied Recycle Bin, %temp%, etc. Deleting/moving user files or adding RAM is not an option. Now I have a USB 3 7200 RPM drive, it's connected to a USB 3 port and is really fast. Is there a way to create a swap file on that drive?

• Linux router and firewall with IP accounting

  - by Andrew

  I'm working on a project to replace my organisation's aging Slackware gateway/router/firewall machine in our colo rack. Previously we used rc.firewall but we are now looking for something more modern and easily configurable. The requirements are: Act as a gateway router & firewall Port forwarding to a Terminal Server in the colo IP/traffic accounting, preferably accessible via SNMP (already using cacti for other servers) Possibility of acting as a PPTP server & routing these connections Is not an out-of-the-box Cisco product (don't have the finances or support to maintain it) I'd prefer to use Ubuntu or some other Debian-based distro but something that integrates everything we're looking for is certainly an option if it offers all the desired features and is easy to configure. Is there a simple set of packages that will provide me with the Firewall & Accounting features, or am I best served with a custom-built distro / other solution?

• Server 2008 Web Edition IIS6 SMTP conflict

  - by user219313

  I'm using IIS6 Manager to setup the SMTP service on Windows Server 2008 Web Edition. There seems to be a conflict (port 25?) which means that I cannot start and stop the Default SMTP server within IIS6. I can start and stop it with the services.msc snap in and this is reflected in state of the SMTP server in IIS6 manager. I'm worried that none of the settings I want to get at within IIS6 (logging, authentication etc..) are having any effect. None of these settings are available within IIS7 in Web Edition.

• Can't perform ODBC connection to MySQL server on local network

  - by Emmanuel

  I have a wamp server running on LAN ip address 192.168.1.101 . From the browser on my PC which is on the LAN I can access the webserver and have as well set the phpmyadmin.conf file to be able to access the phpmyadmin interface. This works smoothly. On the wamp server I have a database which I'd need to access from any PC on the LAN using the MySQL Connector/ODBC. The problem is that I do not manage to setup the connection correctly. Here are the paramenters I use: Data Source Name: test_connection Description: test conenction Server: 192.168.1.101 Port: 3306 User: root Password: Database: The error message I get is the following: Connection Failed: [HY000][MySQL][ODBC 5.1 Driver]Can's connect to MySql server on '192.168.1.101' (10060) Would anybody have a hint to set up correctly the connection?

• Are there any negative impact running all services on a single static IP?

  - by Jake

  I need to setup a VPN trunk (with remote branch office location), Video Conference and Web Server on-premise in the office. I am used to ISP providing blocks of 8 or 16 IPs. But I have a new ISP which says they only can provide a single IP. Are there any issues with running all services on a single IP? I don't think this has any thing to do with bandwidth..? I'm not using SSL certificates... I can do port forwarding to different machines... What else...? Disclaimer: I am a programmer by training. Sorry for noob question.

• Remote Desktop connection repeatedly aborting

  - by DerKlaus

  I connect to my workplace computer using Remote Desktop. After 1-2 minutes the application freezes to tell me after one more minute that the connection was aborted. It then reconnects. Everything works again for 1-2 minutes. Then the process repeats. Probably Forever. My coworkers do not experience such problems when connecting to the workplace. My workplace computer: Windows 7 32bit My home computer: Windows 7 64bit connected to the internet via WLAN-router with integrated ADSL modem (Linksys WAG200G) Things I already tried to fix the problem: disabled the Windows firewall disabled the other firewall reduced the MTU upgraded the firmware on the router configured port-forwarding to forward all packets to my home computer The problem remains unchanged. What could be the cause of the connection aborts? What else can I try to fix the connection? Thanks in advance.

• Freebsd or Linux? as BGP router over 100mbps

  - by Yucong Sun

  I am building a server to act as a BGP border router for my 100mbps uplink in ISP. I needs these feature: 1) Dual stack BGP peering/routing (at least 100Mbps, maybe more). 2) Potential full internet BGP feed. 3) Some basic ACL functionality. The hardware is L3426/8G ram. NIC will be on-board dual port Broadcom 5716. I've worked with Linux extensively before and it seems to be able to handle 100mbps, but I heard FreeBSD is faster on networking stuff. Which one should I use? And do we have some performance benchmark numbers out there? Cheers.

• How does bridged networking work?

  - by agz

  How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

• How can I monitor network traffic in an all Mac home network?

  - by raiglstorfer

  I have an all Mac network consisting of an Airport Extreme, 1 MacPro, 1 Mac Mini, 2 MackBook Pros, 2 iPads, and 2 iPhones. The Mac Pro is connected directly to the Airport Extreme via Cat5 and the rest is all running via Wireless. Lately I've been getting prompted by Google to enter Capchas frequently. The message states that I might have software running on my network I'm not aware of. My wireless router is password protected using WPA2 Personal and I frequently change my password so I don't think someone is using the network from outside (but I've no way to confirm this). I'm looking for a relatively cheap (preferably open source) solution that would enable me to monitor and profile the network usage by machine and port. Can someone recommend a solution?

• Apache 2.2.16 + PHP 5.2.14 sometimes causes Apache to not stop properly

  - by ZiggyTheHamster

  Sometimes, Apache decides not to shut down nicely. killall apache2 or kill -9 (apache2 PID here) shuts it down so that it can actually start back up without the port being in use. Other posts seem to indicate that PHP 5.2 might have issues hanging up Apache. I'm using the worker MPM on an x86_64 Gentoo Linux system if that helps. Any other things I should consider hanging up Apache besides PHP? Should I be stopping Apache with /etc/init.d/apache2 gracefulstop instead of /etc/init.d/apache2 stop?

• Security question pertaining web application deployment

  - by orokusaki

  I am about to deploy a web application (in a couple months) with the following set-up (perhaps anyways): Ubuntu Lucid Lynx with: IP Tables firewall (white-list style with only 3 ports open) Custom SSH port (like 31847 or something) No "root" SSH access Long, random username (not just "admin" or something) with a long password (65 chars) PostgreSQL which only listens to localhost 256 bit SSL Cert Reverse proxy from NGINX to my application server (UWSGI) Assume that my colo is secure (Physical access isn't my concern for the time being) Application-level security (SQL injection, XSS, Directory Traversal, CSRF, etc) Perhaps IP masquerading (but I don't really understand this yet) Does this sound like a secure setup? I hear about people's web apps getting hacked all the time, and part of me thinks, "maybe they're just neglecting something", but the other part of me thinks, "maybe there's nothing you can do to protect your server, and those things are just measures to make it a little harder for script kiddies to get in". If I told you all of this, gave you my IP address, and told you what ports were available, would it be possible for you to get in (assuming you have a penetration testing tool), or is this really protected well.

• Running dnsmasq as an authoritative DNS server

  - by Lord Loh.

  I am trying to implement a dynamic dns service for my computers. I have pointed h.lohray.com to my EC2 instance in the NS record of lohray.com and have installed dnsmasq on that system and have made sure to unblock the firewall port. For now, I have statistically added an entry on my /etc/hosts file. 129.118.19.163 i7.h.lohray.com however, i7.h.lohray.com does not resolve correctly with nslookup or dig :-( This is the only time I could have this resolved (online nslookup) - 50.19.103.190 is the IP address of the EC2 instance where dnsmasq is running. Where could I have gone wrong?

• Can I set up OpenVPN on two or more machines so that they can each act as client and server?

  - by ianfuture

  The question summarises what I want to achieve. In more detail: I have a Windows XP Pro PC at a work location that I want to be able to access my home Windows XP Pro PC and other home computers from. But I also want to be able to connect to the work PC from home. I think the term generally used is a "mesh" network. Can I do this with OpenVPN ? If so how would I do it? What are the most important things to remember to do? EDIT: The work Windows XP Pro PC is largely managed by IT Dept, I do have local admin rights to install things. Some settings are disabled. My main concern was firewalls and port forwarding on the work PC. Any suggestions?

• What could cause my LAN Pings be greater than 100ms?

  - by James Holland

  I have 2 servers (Both: Windows Server 2008, Dual Xeon 2.8Ghz, 32GB RAM, 8 x 15k SAS Drives). One of them is a DC / Web server / Exchange Server, the other is a SQL Server (2008). I have a 48 port Netgear GS748T Gigabit switch. When I ping from server to server, I get ping times <1ms, great, but when I ping from a PC, I get varying pings from the occasional <1ms to 500ms!! If I log into either server and look at Task Manager, CPU usage peaks at 20%, memory usage is 100%, but I am led to believe this is normal as Exchange will just use as much as you have, and release it when requested. Network usage peaks at 1%. I really don't understand how the ping can vary that much. I know I am giving very little info, but this is all I know, I apologise, but can anyone help? In response to question, I have pinged by both IP address and hostname, no difference in ping times.

• Windows 7 Internet Sharing - How to have simultaneous Internet Access to my client

  - by Marl

  The condition: I'm running on windows 7, I'm using a usb broad band for my computer, then my computer is connected to the router tp-link tl-wr340g (in this sense my computer is the internet source since my router has no usb port for this type of broad band). I set the broad band to have internet sharing. I got 3-4 client connected through the router. The problem is whenever a client is using the internet, other clients including me don't have internet connection, additionally, If I have the internet access other clients don't have internet access. In my setup in windows XP (bridging the broad band and the router network) it works perfectly fine, every one has simultaneous internet.
