• Why I Love Microsoft Development

  - by Brian Lanham

  I've been writing software for a while and recently had an opportunity to broaden my horizons and start developing for iOS. We decided to leverage, as much as possible, our existing skills and use MonoTouch and MonoDevelop by Novell.    For those of you who do not know, Mono is a .NET port originally designed for Linux but adapted for other platforms as well. MonoTouch is a port specifically for building iOS applications using the .NET framework. MonoDroid is a port (in CTP-esque release) for Android.   A MISSING COMPONENT - VISUAL DESIGNER   MonoDevelop lacks one very significant component compared with other tools I am using: NO VISUAL DESIGNER. Instead of using an integrated visual designer, MonoDevelop shells to the Mac OS "Interface Builder".  Since MonoDevelop lets me have a "Visual Studio-esque" feel *and* I get to use C#, AND it's FREE, I am gladly willing to overlook this.  In fact, it's not even a question.  Free?  Sure, I'll take it with no Visual Designer.   In my experiences I've grown from UNIX and DOS to .NET development through many steps. Java/JSP/Servlets; Windows; Web; etc. I've been doing .NET for quite a few years and I guess I just got "comfortable" with the tools.   WHY AM I NOT GETTING IT?   Interface Builder (IB) is amazingly confusing for me. I had the opportunity to speak at the Northern VA Code Camp on 12/11/2010. My presentation was "Getting Started with iOS Development using MonoTouch and C#".    At the visual design part of the presentation, I asked one of the 3 or 4 Mac developers in the room about my confusion with the IB. I don't understand why the "Classes" list includes objects. I don't understand what "File's Owner" is. And, most importantly, WHAT THE HECK IS AN OUTLET AND WHY IS IT NECESSARY?!?!?"   His response to these question (especially Outlets): "They did it wrong."   I'm accustom to a visual designer that creates variables for graphical widgets for me. Not IB. Instead, I have to create "Outlets" manually. I still do not understand why and, the explanation from a seasoned Mac developer is that it's wrong. (He received nods of confirmation from the other Mac devs in the room.)   I LOVE MS DEV   I love development for Microsoft platforms using Microsoft development tools. I love Windows 7. I love Visual Studio 2010. I love SQL Server. Azure, Entity Framework, Active Directory, Office, WCF/WF/WPF, etc. are all designed with integration in mind. They are also all designed with developers in mind.   Steve Ballmer recently ranted "It's the developers!" That's why it is relatively quick to build apps using MS tools. Clearly, MS knows that while we usually enjoy building technology solutions, we are here to make money. And we need tools that accelerate our time to market without compromising the power and quality of our solutions.   So, yeah, I am sucking up I guess. But I love Microsoft Development. Thank you, Microsoft, for providing the plethora of great development tools.    P.S. (but please slow down a bit…I'm having trouble keeping up!)

• What alternatives to Animated GIFs are supported on all modern browsers?

  - by Clay Nichols

  I was looking for an alternative animated images to Animated GIFS. But per CanIUseit support for APNGs seems to being phased out. And MNG support isn't even listed there and pages about it don't even mention Chrome (suggesting those pages are very very old) Clarification: This is for a web app, so it'll need to support: - Safari on iPad (so can't depend on extensions) - Chrome on Windows and Mac - Safari 6.0+ on Mac - Chrome on Android

• OS X server large scale storage and backup

  - by user135217

  I really hope this question doesn't come across as trolling or asking for buying advice. It's not intended. I've just started working for a small ad agency (40 employees). I actually quit being a system administrator a few years ago (too stressful!), but the company we're currently outsourcing our IT stuff to is doing such a bad job that I've felt compelled to get involved and do what I can to improve things. At the moment, all the company's data is stored on an 8TB external firewire drive attached to a Mac Mini running OS X Server 10.6, which provides filesharing (using AFP) for the whole company. There is a single backup drive, which is actually a caddy containing two 3TB hard drives arranged in RAID 0 (arrggghhhh!), which someone brings in as and when and copies over all the data using Carbon Copy Cloner. That's the entirety of the infrastructure, and the whole backup and restore strategy. I've been having sleepless nights. I've just started augmenting the backup process with FreeBSD, ZFS, sparse bundles and snapshot sends to get everything offsite. I think this is a workable behind the scenes solution, but for people's day to day use I'm struggling. Given the quantity and importance of the data, I think we should really be looking towards enterprise level storage solutions, high availability and so on, but the whole company is all Mac all the time, and I cannot find equipment that will do what we need. No more Xserve; no rack storage; no large scale storage at all apart from that Pegasus R6 that doesn't seem all that great; the Mac Pro has fibre channel, but it's not a real server and it's ludicrously expensive; Xsan looks like it's on the way out; things like heartbeatd and failoverd have apparently been removed from Lion Server; the new Mac Mini only has thunderbolt which severely limits our choices; the list goes on and on. I'm really, really not trying to troll here. I love Macs, but I just genuinely don't know where I'm supposed to look for server stuff. I have considered Linux or FreeBSD and netatalk for serving files with all the server-y goodness those OSes bring, but some the things I've read make me wonder if it's really the way to go. Also, in my own (admittedly quite cursory) experiments with it, I've struggled to get decent transfer speeds. I guess there's also the possibility of switching everyone off AFP and making them use SMB or NFS, but I understand that this can cause big problems with resource forks and file locks. I figure there must be plenty of all Mac companies out there. If you're the sysadmin at one, what do you use? Any suggestions very gratefully received.

• What is a good C or Obj-C framework for manipulating Git Repositories?

  - by Andrew Theken

  What Obj-C/C libraries have you used for manipulating git repos in your Mac apps? I am working on a Mac app that I would like to be able to clone and modify git repos. Using git directly is not an option as it is GPL and I'd like to sell my app commercially without opening the source. I've seen libgit2, which I could link, but I'm not sure how to do that properly, and it doesn't appear to implement any of the things necessary for pushing/pulling repos over the git protocol.

• Nautilus copies files but not directories from samba server on OS X

  - by camsolo

  I need to copy files from OS X on a Mac to Ubuntu on a PC. I enabled File Sharing on the Mac and selected the samba option. I was then able to connect to the samba server in Nautilus. Copying files was no problem, but copying directories failed, with the error message "is a directory". I can accomplish what I want using samba in the terminal. But it would be more conveninient to do this in Nautilus.

• MAMP like tool for ubuntu

  - by hrishikeshp19

  I am from mac os x background. To control my apache, mysql, and php, I used to use MAMP tool available for mac os x. On my ubuntu, I have installed all the required softwares but, I want a good UI tool to control my apache. To be specific, I change my document root too often, so I want a GUI tool to where I can just browse for desired document root, and restart the server. Is there any such tool available?

• Should I be running VM's(Virtual Box) for development on the same hdd as my os or a external usb (2.0) HDD or usb (2.0) flash drive

  - by J. Brown

  I have a mac book pro (7200 rpm / 8GB ram) and I like the idea of virtualized development environments as I like to experiment with different technologies and don't like to have environmental cross contamination. I would like to know for the vm's I run (rarely 2 at time..almost always 1 vm at a time) should the virtual hdd be on my laptops native hdd or some external form (usb hdd, usb flash, or since i have mac express card based sad ?). I don't mind maxing out my ram to 16GB if thats a better option to have in the mix. Thank you

• How do I configure Ubuntu Server as Primary Domain Controller for Windows 7

  - by B. C.

  I have a Mac server running OS X Server 10.5 Server and as a PDC for our Windows XP systems. I'd like to use the OS X Server as a PDC for our Windows 7 boxes but the version of Samba in OS X Server is not compatible with Windows 7. It appears that my best bet is to use Ubuntu Server as my PDC. I want the Windows boxes to obtain authentication information from the Mac Server's LDAP. Any suggestions are appreciated.

• Incoming traceroute blocked by ufw

  - by Tobias Timpe

  One of my Proxmox VMs running Ubuntu 13.04 won't accept incoming trace routes while ufw is enabled. What command do give ufw to allow incoming traceroute(6)s?

• KVM recommendations

  - by alex

  I recently tried out a cheaper KVM solution, a dual monitor one with a USB hub and audio/mic support. It seemed the perfect KVM. However, these are my experiences. When using my keyboard via the PS/2 connection, none of my multimedia keys work (useful, because it has a volume control and my speakers do not, only on a wireless remote control.) I plugged the keyboard in via the USB port - and it seemed to work. However, I believe to switch the hub from PC to Mac, you need to use a keyboard combo, which is only supported when the keyboard is plugged in via PS/2 Sometimes the middle mouse button doesn't work when connected via PS/2. The multi monitor is VGA - I just found out by the looks of things my Mac Mini outputs DVI Digital only (though this is my fault!). Mac works with 2 screens, but switching and switching back can cause it not to display on the 2nd screen unless I go detect displays again. My question is - is there a KVM out there that supports these features? USB keyboard and mouse inputs will full multimedia keys support Dual monitor DVI connections Hotkey to change PCs and physical button USB hub Emulate screens attached when switching to a different computer Works with PC and Mac Audio / Microphone support Does one exist, that won't cost the world? So far the only one that seems to support all this (that I can tell) is this one. UPDATE I ended up buying the Aten CS1642. It's expensive, but it seems to work great!

• One host on a network can't connect to one other host

  - by Max Williams

  I'm on a local network with a few other people. On of the hosts is a virtual machine running in virtualbox on a mac, which has the ip address 192.168.0.35 (the VM that is, not the mac host). Everyone except one guy can connect (ie ping, ssh etc) to that machine. When that one guy tries to ping it he gets Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 which i understand is just how certain mac os's report an unreachable connection. He can ping all the other hosts on the network, ie our computers, and we can all ping the VM fine and connect to it with no problems etc. His ip is 192.168.0.17. I ssh'd onto his machine (as a new user 'anon') and saw the same problems. I can ssh onto the 192.168.0.35 VM as well. From there, i can ping other users, but when i ping the problem guy, it's unreachable that way round as well. He restarted his mac, and was fine for a while. Then, just stopped working again. He's got a different IP to before. Any ideas, anyone? Don't know enough about this stuff to even diagnose the problem. thanks, max

• Switch Windows 8 from a hybrid MBR/GPT => GPT only on Macbook Pro Retina

  - by Sid

  I used DiskUtility+Bootcamp Wizard to setup my hard drive for Windows 8 (final MSDN). Somewhere in that process, the Apple tools turned my GPT disk into a hybrid MBR/GPT. All my 4 primary MBR partitions are used up, so when I try turning on Bitlocker in Windows 8, it complains about not finding a System drive. I know on Windows 8 the Bitlocker setup tries to create the 200(?)MB system partition if it's missing. However with all 4 partitions filled I suspect it can't create system drive = it can't find it = throws back an error like "BitLocker Setup could not find a target system drive. You may need to manually prepare your drive for BitLocker". I've already tried disabling hibernation, swap file etc. Now I'm thinking that if I were to get rid of the MBR scheme altogether, perhaps I can be alright within the GPT world without MBR's 4 primary partitions limit. So, how can I get rid of the MBR tables on the hybrid scheme in a manner that still leaves Mac OS and Windows 8 in working conditions? Details: Hardware is the MacbookPro Retina. Primary MBR partitions are consumed as follows: EFI partition HFS+ partition (=encrypted, therefore ="Apple_CoreStorage") HFS+ partition (Recovery partition, contains unencrypted Mac bootloader) NTFS partition (Windows8 all-in-one partition) diskutil list output sid-mbpr:~ sid$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_CoreStorage 160.0 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Basic Data Win8 90.1 GB disk0s4 GPT vs MBR addresses sid-mbpr:~ sid$ sudo gptsync /dev/rdisk0 Password: Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 312909639 Unknown 3 312909640 314179175 Mac OS X Boot 4 314179584 490233855 Basic Data Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 312909639 ac Apple RAID 3 312909640 314179175 ab Mac OS X Boot 4 * 314179584 490233855 07 NTFS/HPFS Status: GPT partition of type 'Unknown' found, will not touch this disk.** **: Ignore this message, the gptsync tool is old and doesn't understand the UUID for "Apple_CoreStorage" / FileVault2 partitions. Since LBA addresses are alright, safe to ignore this message.

• OS X Client & Ubuntu Server - Best way for client to access files on server?

  - by Camsoft

  I've got a local development web server running Ubuntu. I also have an iMac running OS X 10.6 which I use a client and is my development machine. I'm currently have Samba server installed on my Ubuntu server. I have shares setup for all the website directories. I then use my Mac and Coda to edit the files via their shares. This generally works really well but I noticed that my Mac was writing loads of resource fork ._filename files everywhere. I found out the following about the files: These files are created on volumes that don't natively support full HFS file characteristics (e.g. ufs volumes, Windows fileshares, etc). When a Mac file is copied to such a volume, its data fork is stored under the file's regular name, and the additional HFS information (resource fork, type & creator codes, etc) is stored in a second file (in AppleDouble format), with a name that starts with "._". (These files are, of course, invisible as far as OS-X is concerned, but not to other OS's; this can sometimes be annoying...) Does anyone know of a way of sharing files between a Mac client and a Linux server that is most compantable between the two operation systems? Ideally it needs to support the HFS filesystem so that the resource forks are not created and it also needs to support the permissions between server and client.

• samba share not on network after upgrading to Ubuntu 12.04LTS. [migrated]

  - by Sylvain Huard

  I just upgraded an old Ubuntu box to 12.04LTS (machine named A-Ubuntu). This is an upgrade not a format re-install. All the accounts and config were preserved. The basic setup is a local network with 2 Ubuntu machines (let say A-Ubuntu, B-Ubuntu) and a MAC (C-MAC). Before the upgrade, all of them could see each other by their names not only the IP address. The local network has a D-Link Router where everybody is connected with RJ-45 wired etherenet (not wi-fi). Since the A-Ubuntu upgrade, we can't see this machine name on the Network and its name is not on machine list in the D-Link router anymore. We can see it's IP address only. I can't access A-Ubuntu from the other two by its name but I can ping it with its address (192.168.0.109). From A-Ubuntu, I can connect and see the shared samba folders on B-Ubuntu and C-MAC. But from B-Ubuntu and C-MAc, I can't connect to A-Ubuntu. Correct me if I'm wrong but this tells me that Samba should be fine and the real problem is that A-Ubuntu does not advertise its name on the Network so the D-Link does not have it in its table so nobody else finds it. After a lot of googling, I see that it is the job of avahi and mdns to do so. Those packages are running, I checked multiple config files for samba, avahi, mdns to see as if it is like the examples on the WEB and also similar to what I find on the working B-Ubuntu machine. This is the same. I did multiple service restart with samba, avahi, remove the firewall to make sure it does not block the hostname broadcast. I rebooted multiple time to make sure the update I was making were effective. Still, Can't see the A-Ubuntu name on the network. Any idea what it can be?, Where to look next?

• What is the best VM for developing WPF apps from within OS X?

  - by MarqueIV

  All of my machines are Macs (Mac Pro, MacBook Pro, MacBook Air and Mac Mini (and Apple TV 2.0 too! :) ) but for my day-job, I develop .NET/WPF applications. Normally I just boot into Boot Camp and develop that way, which of course works great, but there are times when I need to simultaneously get to things on my Mac-side of the equation, so I've bought both VMware 3.1 and Parallels 6. Both work, however, even on my Mac Pro where I paid to upgrade to the better video cards (the NVidia 8600s I think vs. the stock ATI cards) the WPF performance bites!! Now this confuses me since both boast that they support not only hardware-accelerated OpenGL 2.1, but also hardware-accelerated DirectX 9 (VMware even allegedly supports DirectX 10!) via their respective virtual drivers and both can run 3D games just fine, even in a window. But even the simple act of resizing a WPF window that has a tiled background results in some HIDEOUS repainting and resizing behaviors. It's damn near closer to what you'd expect over RDP let alone a software-only renderer (forget accelerated hardware completely!) So... can anyone please tell me WTF WPF is doing differently? More importantly, how can I speed up the WPF performance? Should I switch to VirtualBox that also has support for DirectX? Or am I just gonna have to 'byte' the bullet (sorry... had to. So I like puns! Thank Jon Stewart!) and continue using Boot Camp?

• Windows 2008 R2 Servers Sending Arp Requests for IPs outside Subnet

  - by Kyle Brandt

  By running a packet capture on my my routers I see some of my servers sending ARP requests for IPs that exist outside of its network. For example if my network is: Network: 8.8.8.0/24 Gateway: 8.8.8.1 (MAC: 00:21:9b:aa:aa:aa) Example Server: 8.8.8.20 (MAC: 00:21:9b:bb:bb:bb) By running a capture on the interface that has 8.8.8.1 I see requests like: Sender Mac: 00:21:9b:bb:bb:bb Sender IP: 8.8.8.20 Target MAC: 00:21:9b:aa:aa:aa Target IP: 69.63.181.58 Anyone seen this behavior before? My understanding of ARP is that requests should only go out for IPs within the subnet... Am I confused in my understanding of ARP? If I am not confused, anyone seen this behavior? Also, these seem to happen in bursts and it doesn't happen when I do something like ping an IP outside of the network. Update: In response to Ian's questions. I am not running anything like Hyper-V. I have multiple interfaces but only one is active (Using BACS failover teaming). The subnet mask is 255.255.255.0 (Even if it were something different it wouldn't explain an IP like 69.63.181.58). When I run MS Network Monitor or wireshark I do not see these ARP requests. What happens is that on the router capturing I see a burst of about 10 requests for IPs outside of the network from the host machine. On the machine itself using wireshark or NetMon I see a flood of ARP responses for all the machines on the network. However, I don't see any requests in the capture asking for those responses. So it seems like maybe it is maybe refreshing the arp cache but including IPs that outside of the network. Also when it does this NetMon doesn't show the ARP requests?

• Ubuntu 12.04 suddenly cannot connect to WPA2/WPA Personal protected connection. Windows 7 can

  - by d4ryl3

  I have a laptop with Windows 7 and Ubuntu 12.04. I have a Cisco E1200 and when I set it up, it created 2 SSIDs. Let's name them: MyConnection (WPA/WPA2 personal), and MyConnection-Guest (no authentication, guest password entered via web browser). I had no problem connecting to MyConnection before, either in Windows 7 and Ubuntu. But now, I can't access MyConnection on Ubuntu. It just says "connecting..." then disconnects after a while. But I'm able to access the internet (on Ubuntu) when I connect to MyConnection-Guest. MAC filtering is off (even if it's on its MAC address is in the white list). Any idea why I'm unable to connect to MyConnection in Ubuntu? Thanks. Update: My Ubuntu installation can connect to ANY WiFi connection (WPA/WEP/no auth), except for MyConnection. Update2: This is what "The not so easy way" returned: Initializing interface 'eth1' conf '/etc/wpa_supplicant.conf' driver 'default' ctrl_interface 'N/A' bridge 'N/A' Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf' Reading configuration file '/etc/wpa_supplicant.conf' Priority group 0 id=0 ssid='MyConnection' id=1 ssid='MyConnection' id=2 ssid='MyConnection' id=3 ssid='MyConnection' WEXT: cfg80211-based driver detected SIOCGIWRANGE: WE(compiled)=22 WE(source)=21 enc_capa=0xf capabilities: key_mgmt 0xf enc 0xf flags 0x0 netlink: Operstate: linkmode=1, operstate=5 Own MAC address: xx:xx:xx:xx:xx:xx wpa_driver_wext_set_key: alg=0 key_idx=0 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=1 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=2 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=3 set_tx=0 seq_len=0 key_len=0 wpa_driver_wext_set_key: alg=0 key_idx=4 set_tx=0 seq_len=0 key_len=0 ioctl[SIOCSIWENCODEEXT]: Invalid argument Driver did not support SIOCSIWENCODEEXT wpa_driver_wext_set_key: alg=0 key_idx=5 set_tx=0 seq_len=0 key_len=0 ioctl[SIOCSIWENCODEEXT]: Invalid argument Driver did not support SIOCSIWENCODEEXT wpa_driver_wext_set_countermeasures RSN: flushing PMKID list in the driver Setting scan request: 0 sec 100000 usec WPS: UUID based on MAC address - hexdump(len=16): 16 3b d8 47 9e 24 50 89 96 16 6d 66 35 f3 58 37 EAPOL: SUPP_PAE entering state DISCONNECTED EAPOL: Supplicant port status: Unauthorized EAPOL: KEY_RX entering state NO_KEY_RECEIVE EAPOL: SUPP_BE entering state INITIALIZE EAP: EAP entering state DISABLED EAPOL: Supplicant port status: Unauthorized EAPOL: Supplicant port status: Unauthorized Added interface eth1

• iptables captive portal remove user

  - by Burgos

  I followed this guide: http://aryo.info/labs/captive-portal-using-php-and-iptables.html I am implementing captive portal using iptables. I've setup web server and iptables on linux router, and everything is working as it should. I can allow user to access internet with sudo iptables -I internet -t mangle -m mac --mac-source USER_MAC_ADDRESS -j RETURN and I can remove access with sudo iptables -D internet -t mangle -m mac --mac-source USER_MAC_ADDRESS -j RETURN However, on removal, user can still open last viewed page as many times he wants (if he restart his Ethernet adapter, future connections will be closed). On blog page I found a script /usr/sbin/conntrack -L \ |grep $1 \ |grep ESTAB \ |grep 'dport=80' \ |awk \ "{ system(\"conntrack -D --orig-src $1 --orig-dst \" \ substr(\$6,5) \" -p tcp --orig-port-src \" substr(\$7,7) \" \ --orig-port-dst 80\"); }" Which should remove their "redirection" connection track, as it is written, but when I execute that script, nothing happens - user still have access to that page. When I execute /usr/sbin/conntrack -L | grep USER_IP after executing script I am having nothing returned, so my questions: Is there anything else that can help me clean these track? Obviously - I can't reset nor mine, nor users network adapter.

• Packets being dropped by iptables

  - by Shadyabhi

  I am trying to create a Software Access Point in linux. I followed the blog here. Steps I performed: Started dhcp server on wlan0. Properly configured hostapd.conf Enabled packet forwarding & masquerading. Two commands executed regarding iptables: iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE iptables --append FORWARD --in-interface wlan0 -j ACCEPT I enabled logging on iptables & I get this in everything.log Jun 29 19:42:03 MBP-archlinux kernel: [10480.180356] IN=eth0 OUT=wlan0 MAC=c8:bc:c8:9b:c4:3c:00:13:80:40:cd:80:08:00 SRC=195.143.92.150 DST=10.0.0.3 LEN=44 TOS=0x00 PREC=0x00 TTL=52 ID=38025 PROTO=TCP SPT=80 DPT=53570 WINDOW=46185 RES=0x00 ACK URGP=0 Jun 29 19:42:03 MBP-archlinux kernel: [10480.389102] IN=eth0 OUT=wlan0 MAC=c8:bc:c8:9b:c4:3c:00:13:80:40:cd:80:08:00 SRC=195.143.92.150 DST=10.0.0.3 LEN=308 TOS=0x00 PREC=0x00 TTL=52 ID=14732 PROTO=TCP SPT=80 DPT=53570 WINDOW=46185 RES=0x00 ACK PSH URGP=0 Jun 29 19:42:03 MBP-archlinux kernel: [10480.389710] IN=eth0 OUT=wlan0 MAC=c8:bc:c8:9b:c4:3c:00:13:80:40:cd:80:08:00 SRC=195.143.92.150 DST=10.0.0.3 LEN=44 TOS=0x00 PREC=0x00 TTL=52 ID=14988 PROTO=TCP SPT=80 DPT=53570 WINDOW=46185 RES=0x00 ACK FIN URGP=0 Jun 29 19:42:03 MBP-archlinux kernel: [10480.621118] IN=eth0 OUT=wlan0 MAC=c8:bc:c8:9b:c4:3c:00:13:80:40:cd:80:08:00 SRC=195.143.92.150 DST=10.0.0.3 LEN=44 TOS=0x00 PREC=0x00 TTL=52 ID=63378 PROTO=TCP SPT=80 DPT=53570 WINDOW=46185 RES=0x00 ACK FIN URGP=0 I have almost no knowledge of iptables, all I did was through googling.

• How can I automate or script daily downloads for any new anti- virus databases, and then have the program scan my drive?

  - by Macgrimm

  Howdy all Super Users" I humbly ask if any Super User can direct this long time, gray haired Apple Tech in the right direction on this issue. I believe there probably are many ways to skin this cat. But I am looking to find simply the best, most unattended way to get it done. Any help will be greatly appreciated. also (I know there are much better softwares out there for the Mac so please don't go there! The politics of this company dictate which Anti virus we have to use) anyway without any further wait: basically I am trying to automate 2 very important functions of Mc'Afee anti-virus for Mac. First I want to automate the process of retrieving new virus definition files, and second I want to automate the process of scanning for viruses. It turns out that Using Mc'Afee Anti-Virus for the Mac are both manual functions. And they left up to the user (per user account) to perform. Depending on all of about 150 MAc users to perform these 2 tasks themselves is around 65% compliance. My question then is: If I wanted to use the command line such as (open /Applications/McAfee\ Security.app) It will open up the Security Console. But how can I make command Mc'Afee go out and grab the definition files and scan the computer? I have to admit I am at a crossroad and Macaltimers has set in. I would really appreciate it if any of you "Super ~ Users" can help me out with this MacAltimers loss of how to what to do. Thanks to All up Front Macgrimm

• Windows 7 using llt for ipv6

  - by Seoman

  The question asked below is based on the specific implementations of the Os not the RFC. Looking on a way to be able to assign a fixed ip address to a host, before it boots I found that Centos 6 works fine with no modifications and Windows 7 does not work at all. As defined in enter link description here exists 3 valid ways of generate a DUID: 1 Link-layer address plus time 2 Vendor-assigned unique ID based on Enterprise Number 3 Link-layer address Looking at the centos, that works fine, I can see the following autogenerated DUID: option dhcp6.client-id 0:1:0:1:19:60:25:f1:52:54:0:6b:b9:9e; and the MAC address for this host is: ifconfig eth1 | grep HWaddr eth1 Link encap:Ethernet HWaddr 52:54:00:6B:B9:9E As you can see, the DUID containts the MAC address. I can assign a fixed ip address to this host by including an entry on my dhcp server similar to: host vm { hardware ethernet 52:54:00:6B:B9:9E; fixed-address6 2001:db8:0:1::200; if packet(0,1) = 1 { log(debug,"VM Request match!"); } } And the Centos 6 gets his ip. On the windows side, I faced a common problem explained on this other link enter link description here As summary, Win7 uses the option 2 of the DUID generation or a variation of this one. On the link explains how to move it to a llt (link layer + time) but is not working fine. If I modify the DUID to one that looks like the one generated on Centos (but with the right MAC) it works as expected. Question 1 How Can I change the DUID generation for Windows 7 to be based on MAC as Centos 6 does? Thanks
