• How can one restrict network activity to only the VPN on a Mac and prevent unsecured internet activity?

  - by John

  I'm using Mac OS and connect to a VPN to hide my location and IP (I have the 'send all traffic over VPN connection' box checked in teh Network system pref), I wish to remain anonymous and do not wish to reveal my actual IP, hence the VPN. I have a prefpan called pearportVPN that automatically connects me to my VPN when I get online. The problem is, when I connect to the internet using Airport (or other means) I have a few seconds of unsecured internet connection before my Mac logs onto my VPN. Therefore its only a matter of time before I inadvertently expose my real IP address in the few seconds it takes between when I connect to the internet and when I log onto my VPN. Is there any way I can block any traffic to and from my Mac that does not go through my VPN, so that nothing can connect unless I'm logged onto my VPN? I suspect I would need to find a third party app that would block all traffic except through the Server Address, perhaps Intego Virus Barrier X6 or little snitch, but I'm afraid I'm not sure which is right or how to configure them. Any help would be much appreciated. Thanks!

• Application that will identify percentage of your system disk bandwidth used on a user-application by user-application basis?

  - by Warren P

  I always (subjectively) feel my computer is far too slow (however fast it is), and so I'm always looking for ways to measure and understand what my computer is actually doing, that is making it seem "slow" to me. It has been my observation that my software-developer workload is most often disk-bound (I am waiting for Disk I/O) more than CPU bound. What has made it worse, is that I am using a corporate PC that has in-memory active-scanning anti-virus software that I do not have control over, and also some IT department mandated services that seem to suck up a lot of available hard-disk bandwidth. The best tool I have seen (in Windows 7) is the Resource Monitor which I usually acess from the button in the task Manager. The disk IO page, however, seems to label Disk Activity at a very low level (for example, showing the Volume Shadow Storage, which is flushing information obviously written by something ELSE other than VSS itself, and then writes to Pagefile.sys, which are obviously due to Virtual Memory faults in some application). What I would like to know is if a utility exists that can add up all direct disk input and output by user-level process, or find the process or service that caused VM or VSS activity. In that way, I hope, you could establish a real idea of how much of your computer's precious disk subsystem bandwidth is attributable to a particular application. here's a scenario: MyApp.exe writes 100k/s and reads 100k/s directly. VSS ends up writing another 100k/s. pagefaults caused inside MyApp.exe cause another 100k/s of writes. So the total "cost" of MyApp.exe running, during a period of time (let's say 1 second) is 400k/s, whereas you can only directly observe half of that, in Resource Monitor. Is there a smarter disk-IO watching piece of software I can use?

• Zabbix doesn't update value from file neither with log[] nor with vfs.file.regexp[] item

  - by tymik

  I am using Zabbix 2.2. I have a very specific environment, where I have to generate desired data to file via script, then upload that file to ftp from host and download it to Zabbix server from ftp. After file is downloaded, I check it with log[] and vfs.file.regexp[] items. I use these items as below: log[/path/to/file.txt,"C.*\s([0-9]+\.[0-9])$",Windows-1250,,"all",\1] vfs.file.regexp[/path/to/file.txt,"C.*\s([0-9]+\.[0-9])$",Windows-1250,,,\1] The line I am parsing looks like below: C: 8195Mb 5879Mb 2316Mb 28.2 The value I want to extract is 28.2 at the end of file. The problem I am currently trying to solve is that when I update the file (upload from host to ftp, then download from ftp to Zabbix server), the value does not update. I was trying only log[] at start, but I suspect, that log[] treat the file as real log file and doesn't check the same lines (althought, following the documentation, it should with "all" value), so I added vfs.file.regexp[] item too. The log[] has received a value in past, but it doesn't update. The vfs.file.regexp[] hasn't received any value so far. file.txt has got reuploaded and redownloaded several times and situation doesn't change. It seems that log[] reads only new lines in the file, it doesn't check lines already caught if there are any changes. The zabbix_agentd.log file doesn't report any problem with access to file, nor with regexp construction (it did report "unsupported" for log[] key, when I had something set up wrong). I use debug logging level for agent - I haven't found any interesting info about that problem. I have no idea what I might be doing wrong or what I do not know about how Zabbix is performing these checks. I see 2 solutions for that: adding more lines to the file instead of making new one or making new files and check them with logrt[], but those doesn't satisfy my desires. Any help is greatly appreciated. Of course I will provide additional information, if requested - for now I don't know what else might be useful.

• The Web Hosting Connundrum for "not quite" developers

  - by saltcod

  Hey all, Apologies if this post feels like its been covered elsewhere, but I don't think it has. I've been down a winding web hosting road. To date, I've tried: Joyent, Media Temple, Bluehost, Hostgator, and finally Linode. The reason for switching are likely obvious to everyone: speed. With the exception of the lightening fast Linode, all of the shared hosts are absolutely sloooow. What do do when you're not really a "developer" While I'v grown addicted to the speed of Linode, I really don't feel like its where I should be. I have this nagging feeling in the back of my mind that one of these days (likely soon), I'm going to run into something that i won't be able to figure out and i'll have days worth of downtime. Just the other day, for example, I realized that one of my domains wasn't sending emails. After 4(!) hours looking into the problem, I still can't get sendmail or postfix to work. Four hours!! I want to be a Drupal expert, not a Ubuntu expert That's really the heart of my problem: I spend way too much time learning Ubuntu's ins-and-outs, and not nearly enough time working on Drupal. So here goes: Is there a web host out there anywhere that offers the speed of Linode, but will let me focus on Drupal instead of sys-admin-ing? Thanks! [ I know, I know. There are going to be lots of people who read this saying - "just learn Ubuntu like a real developer". And I get that. I do. But when I work full-time and try and develop some of these sites in my evenings and weekends, I'm really feeling like the sys-admin stuff gets in the way.

• Linksys SFE2000 Interface

  - by boburob

  I have a real problem with a layer 3 Linksys switch. First, every time it looses power, it seems to reset back to an older config. Not only this, but when this happens it looses interface settings on one subnet. This would not be a problem but I am completely unable to get to the interface on the working side. It allows me to log on and then just displays a blank screen. I have tried this on: IE6 IE7 IE8 IE9 Firefox 3.5 Opera Chrome All with the same results, except for Opera, which loads half the interface but nothing I can really use. I really need to get onto this switch so I can sort out routing and VLAN tagged ports, so if anyone has any ideas on either of these issues please let me know ASAP! Thanks! Also, due to its location and my lack of laptops with serial connections I cannot putty into it. UPDATE: Looked into this a bit more and it looks like this model of switch does not save the current config to boot unless you make sure to save it yourself, which explains the first issue, however the broken interface is more worrying!

• Why does lighttpd keep static files in cache, even when modified on disk ?

  - by Pixelastic

  I am using lighttpd to serve static files. I have a bunch of images in a dir that I regularly update. This will change the file content (and filesize) as well as the modification date, but not their filename. When I access the files through http, the updates are not taken into account and lighty serves the old file. I can manually rename the file to something different, then lighttpd will return a 404 error, and if I rename my file back, I will get the correct updated version. Seems like lightty is using some kind of cache mechanism of its own (which is fine) to return static files. Unfortunatly, it seems that this mechanism doesn't update itself when files are modified. I checked through Wireshark, and my browser is really doing a request to the file, this is not a browser caching issue. It returns a 200 OK when requesting it from an empty cache, and a 304 Not Modified otherwise, as expected. But the file is returned with a wrong Last-Modified header that do not reflect the real last modification date. Maybe there is some config directive that I am not aware of ? I would like the files returned by lighty to reflect the changes made on disk directly, or at least being able to invalidate its cache.

• XAMPP server giving 404 error when requested by ipv4 connection

  - by boyb

  This is in reference to a previous question that I asked and was answered by womble. http://serverfault.com/a/406280/127729 So, now we have the real DNS records, we can do some diagnosis. dig for both A and AAAA on akosiboybastos.broker.freenet6.net gives a valid response, with an appropriate address. Good. dig for both A and AAAA on bastosforum.strangled.net gives the same responses (with a CNAME response thrown in). Also good. This means that the problem is not DNS-related, as those records are in order. wget -6 bastosforum.strangled.net/ gives a 200 OK response. wget -4 bastosforum.strangled.net/ gives a 404 Not Found response. This means that your webserver is misconfigured so that it's not serving the response you desire on IPv4. Given that the initial DNS problem asked in this question has been solved, I would recommend posting a new question with relevant webserver-related configuration, if you can't determine the configuration error yourself. I am using XAMPP(latest version) running phpbb3.0.10 via ipv6 tunnel from freenet6 and my domain is akosiboybastos.broker.freenet6.com, nothing fancy with the installation just out of the box install(with a few cosmetic mod). Both ipv4 and ipv6 traffic can connect using that url, but when I try to put a CNAME record on my test domain which is bastosforum.strangled.net pointing it to akosiboybastos.broker.freenet6.com only ipv6 can connect. As suggested by womble, this is a misconfigured webserver. To be honest I don't know where to start checking on the server as it is fully working if you use the domain given by freenet6 (akosiboybastos.broker.freenet6.com), any info on how to go about this server issue is welcome as i'm really a noob when it comes to computers. regards boyb

• Is it possible to to create a live linux iso containing a win xp virtual machine?

  - by mark

  I would like to have a Linux live system that contains a Windows xp virtual machine. This would be run from a bootable USB flash drive. My attempts so far have been unsuccessful. I created a Lubuntu 12.04 virtual machine with VMware. I updated and configured it to my needs, and installed Virtualbox. I then created a Windows xp vm with Virtualbox in the Lubuntu vm. I tested everything and everything worked, including USB devices. I installed Remastersys in the Lubuntu vm, copied the xp vm folder to the /etc/skel folder then created the custom iso with remastersys. I burned the iso and tested it on a laptop. It worked flawlessly. All programs and wireless networking worked. My problem was the xp vm. Virtualbox started fine but would not run the vm. I have the following error: Result Code: NS_ERROR_FAILURE (0x80004005) Component: VirtualBox Interface: IVirtualBox {c28be65f-1a8f-43b4-81f1-eb60cb516e66}. I ran remastersys again changing the permissions on the skel folder to R W for everyone. I also logged into Lubuntu as root and ran remastersys again. Each iso I created worked fine but would not start the xp vm inside. The last attempt virtualbox gave me an access error stating it can not access the virtual disk. Is what I want to do possible? In theory I don't see why it would not work. Is it a permissions issue? Should I create the iso then add the xp vm after by editing the iso by hand? Using a vm and not real hardware as a build machine a problem? Any ideas? keep any responses in laymens terms. I am still a Linux novice.

• Permissions error when creating desktop shortcut

  - by Ryan M.

  Hey guys, I have a user that's got a weird permissions problem on Windows 7. He's trying to create a shortcut for Outlook on his desktop(he doesn't want it in his start menu or his taskbar...). If we right click the outlook.exe and do Send to Desktop, it works just fine. If we do a search for "outlook" in the search bar, and then try and drag and drop the outlook icon to the desktop, we get the error message "You need Permission to perform this action. You require permission from SYSTEM to make changes to this file: Microsoft Office Outlook 2007". Dragging and dropping other exe's onto the desktop work just fine. They create shortcuts without any problems. But if I try to do ANY of the Office programs (Word, Excel, Outlook, etc..) I get this permission error. Any ideas? He's using an A.D. account and he's in the local administrators group. He's an executive so he's not accepting "this isn't a real problem because I found another way to make a shortcut" as an answer. Any help is appreciated.

• Can next hop address be same as destination address?

  - by Raj

  Like if host address is 100.0.0.1 and next hop address is 100.0.0.2 and destination ip address is also 100.0.0.2 Is this a valid use case? Any real life usage? <dest ip> <next hop> ip route 100.0.0.2 255.255.255.255 100.0.0.2 weight 1 next-hop-vrf GlobalRouter Above is the command on a router inside a VRF. 100.0.0.2 is pingable from host. 100.0.0.1 & 100.0.0.2 are an ip address assigned to a VLAN on host & destination respectively. On a linux box, Such configuration is valid. [root]# netstat -r -n Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 55.55.55.55 55.55.55.55 255.255.255.255 UGH 0 0 0 eth0 [root]# ip route show 55.55.55.55 via 55.55.55.55 dev eth0 As per my understanding, If a destination IP is reachable (i.e in the same subnet of host IP) we dont need a next hop. I came across one application for using next hop for destination IP in same subnet (i.e for VPN) See this: Will packets send to the same subnet go through routers? If next hop != destination IP but they are in same subnet as that of host, is a valid scenario for VPN, then i am wondering what are the applications of next_hop==dest_ip & subnet same as host? This is my first post in Super User. Extremely happy with the quick and warm response.

• Over gigabit connection, Teracopy does 31MB/s, but Windows 8 does it at ~109MB per second?

  - by Gaurang

  I got my brain-melting first taste of Gigabit networking today, between my 2011 MacMini and Windows 8 Pro desktop connected via Cat.5e to Linksys WRT320N(sporting dd-WRT). After making sure that the line speed on both systems showed 1Gbps, I proceeded to copying a 2.4GB MP4 from the Mini to the Win 8 desktop (SMB sharing). Although satisfied with the 30-34 MB/s that Teracopy was showing (that was a proper step-up for me from 10 MB/s), I still was curious about this massive difference in the advertised and real-world speed. 2 hours of Google had me believing that there were other factors that resulted in less speed, SMB being one. So just for the sake of doing it, I iPerf'd both the systems and guess what that showed - around 875mbps on both systems! I then stumbled upon this little piece of info after which I turned off Teracopy and copied the same file through Windows 8's regular copier. 109 MB/s. Molten brains :) What exactly is causing this? And can I enable such speeds via Teracopy? I really dig the extra features that Teracopy has, will surely miss them now :D

• Network Sniffing and Hubs

  - by Chris_K

  This will likely seem naive to the experts... but it has been on my mind lately. For years I've been using ntop and a cheap 4 port hub to sniff client networks to determine who's doing what -- and how much. Great way to see what's going on when they call and say "Geeze, the network seems really slow today." No need to bring in a managed switch (or access the existing one) and no need to configure spanning or mirroring. I just drop in the hub inline where I want to measure. Lately I noticed it is just about impossible to buy a real honest-to-goodness hub anymore. While looking for a new one, I had someone tell me that I should be sure to get a full-duplex hub or I'd only be seeing half the traffic when I monitor. Really? I've been using a crusty old Netgear DS104 all this time. No clue if it is half or FD. Have I really been understating my measurements? I'm just not bright enough about the physical layer to really know... Side note: Just ordered a Dualcomm Ethernet Switch TAP as a hub replacement. Seems like a nifty gadget. Any notes or tips about it would be welcome in the comments :-)

• Why am I unable to mount my USB drive (unknown partition table)?

  I'm a real newbie to linux. Anyway the problem is that my USB doesn't get recognized anymore which is really annoying because I need information from it.

• Windows Server 2003 (w/Exchange) move to new machine

  - by James Booker

  I have an ageing domain controller (the only one on a 10-pc network) which needs rebooting often. I have a Dell Poweredge 2850 server doing nothing, so I'd like to move the DC to that, but here's the catch - I don't have Win2k Server Std install media any more as it's been lost. I purchased "Easus Todo Backup Advanced Server" which claims to be able to recover to dissimilar metal, but it's not quite working (although I don't think it's the product's fault) I know the server and PERC RAID card are good because I installed Ubuntu on the logical drive (4 x 72GB disks RAID 5) no problems. I've booted frmo the Easus Todo backup CD (which is WinPE based) and recovered to the logical disk on the RAID (after installing driver inside the WinPE environment from a NAS drive) The problem is when I boot the server, I can get the OS selection menu, but any option results in a blank screen, with no errors. I figure this is probably because the driver wasn't installed on the old machine (which is IDE-based (i know, i know!) and doesn;t have a RAID controller) I've booted from the CD and copied the mraid35x.sys file to the c:\windows\system32\drivers folder on the recovered system, but it makes no difference. I made a boot.ini with rdisks 0-10 defined, and booting from each of these resulted in a file error (i.e. 'this isn't a real disk') - the only disk that gets any response (the blank screen) is multi(0)disk(0)rdisk(0)partition(1) which just gives me the blank black screen and no disk activity. Is there any way I can force the drvier to be installed on the source system (so i can do a full backup again), i've tried right-clicking the oemsetup.inf and clicking install, but it didn't actually do anything. I attempted to force it with the 'Add new hardware' wizard and forcing with the 'have disk' option but it still gave me no hardware to select. Also I've got an identical machine running WinXP which uses the PERC driver successfully (which was obviously done at install time) and the boot.ini settings are the same : multi(0)disk(0)rdisk(0)partition(1) Any ideas would be appreciated.

• What is the risk of introducing non standard image machines to a corporate environment

  - by Troy Hunt

  I’m after some feedback from those in the managed desktop or network security space on the risks of introducing machines that are not built on a standard desktop image into a large corporate environment. This particular context relates to the standard corporate image (32 bit Win XP) in a large multi-national not being suitable for a particular segment of users. In short, I’m looking at what hurdles we might come across by proposing the introduction of machines which are built and maintained by a handful of software developers and not based on the corporate desktop image (proposing 64 bit Win 7). I suspect the barriers are primarily around virus definition updates, the rollout of service packs and patches and the compatibility of existing applications with the newer OS. In terms of viruses and software updates, if machines were using common virus protection software with automated updates and using Windows Update for service packs and patches, is there still a viable risk to the corporate environment? For that matter, are large corporate environments normally vulnerable to the introduction of a machine not based on a standard image? I’m trying to get my head around how real the risk of infection and other adverse events are from machines being plugged into the network. There are multiple scenarios outside of just the example above where this might happen (i.e. a vendor plugging in a machine for internet access during a presentation). Would a large corporate network normally be sufficiently hardened against such innocuous activity? I appreciate the theory as to why policies such as standard desktop images exist, I’m just interested in the actual, practical risk and how much a network should be protected by means other than what is managed on individual PCs.

• Modifying value of "Rating" column within Explorer for arbitrary file types

  - by Fake Name

  Basically, I have a large body of assorted media (text, images, flash files, archives, folders, etc...) and I'm attempting to organize it. Windows Explorer has a rating column, but there seems to be no way to modify the rating of the files short of opening them in their type-specific software (e.g. Media player, or Photo viewer). However, this does not work when the file is of an unsupported type (.rar, .swf ...), or a directory. I'd be more than willing to consider a file-manager replacement (I've alreadly looked at quite a few, Directory Opus, Total Commander, etc...), or even a solution that stores the rating metadata in a hidden file in each folder, or a separate database. The one real critical requirement is the ability to sort by rating, and being filetype-agnostic. Basically, is there any way to categorize a large collection of assorted files by rating that will work with any file type, including directories? - Ideally, there would be an easy way to add arbitrary columns to windows explorer, and edit them directly. However, there seems to be no way to do this. The rating column is the next best thing.

• Oracle 11g Data Guard over a WAN

  - by Dave LeJeune

  Hi - We are in process of looking at using Oracle's Data Guard to replicate our 11g instance from a colo facility in Washington DC to Chicago. To give some basics we have approximately 25TB of storage and a healthy transaction rate in the 1-2K/sec range. Also, because we are processing data in real-time we have a 24x7x365 requirement for processing data. We don't have any respites as far as volume except for system upgrades (once every few months) where we take the system offline but then course experience a spike in transactions when we bring the system back on-line. Ideally we would want the second instance in the DG configuration semi-online in a read-only fashion for reports/etc. We evaluated DG in 10g and were not overly impressed and research seemed to show that earlier versions had issues with replication over a WAN but I have heard good things about modifications the product has gone through w/ 11g. Can anyone confirm an instance of this size and transaction rate being replicated over a WAN and if so what is the general latency? An information or experiences with a DG implementation that is of this size and scope would really be helpful (or larger - I also realize we are still relatively small compared to many others out there). Many thanks in advance.

• Server 2012 - transparent SMB failover without shared discs, possible?

  - by TomTom

  here is the scenario - there is a small set (200gb around) of data that I HAVE to keep available. Those are basically shared VHD images that serve as master images for a lot of our VM's - they then run in differential discs off those. The whole set is "mostly read only". In more detail: A file that IS there and IS used will NEVER change. I may delete files (when absolutely not in use) and add new files, but a file that is there once gets read protection set and that it is until it is retired. Obviously, I need as much uptime as possible. SO FAR we run that by having this directory local on every Hyper-V server. Now I think moving this into our storage fabric. Due to the "it HAS to be there" I pretty much want a share nothing architecture. DFS would be perfect for this - a file never changes, so replication would work nicely. Folders could be replicated to a number of servers, all would reference them from there. Now, that hyper-V supports SMB that could be a good idea to isolate these on a number of servers - we try to move into a scenario where the storage is more centralized. Server 2012 supports always on shares, but it seems that this only works with a clustered disc behind. Is there any way around this for read only file stores? All documentation points to stuff like a shared JBOD - but that would leave me open for file system corruption. I really plan to go quite separately here, vertically - 2 servers, both with SSD only for this, both with their own 2000W separate USV, both with enough bandwidth to handle everything thrown at them (note to everyone tinking this is 10G - this would be SLOW and EXPENSIVE compared to a nice Infiniband backbone). The real crux is that this is an edge case obviously - as the files are read only once in use.

• Truecrypt files corrupted after moving PC into another case

  - by Dygerati

  I recently bought a new PC case and transferred all of my PC hardware into it. The only hardware modification was the addition of two identical ram modules. The entire process went smoothly, and everything worked and booted as before. The only side-effect I found when accessing one my of file-based hidden truecrypt volumes shortly there after. Some of the files in the volume - NOT all - seemed to be entirely corrupted. The directory and file names are garbled characters, but a few of the directories in the same volume appear and function normally. Also, all files in the non-hidden tc volume were still intact. Is this not weird? The only other real change I could think of would be that the hard drives were connected to different SATA ports on the mobo. I really don't know how the truecrypt encryption works well enough to know what could cause this...and the fact that not all the files were corrupted makes it more bizarre still. So, first off (and I'm not too hopeful on this point), would it be possible to restore these files? I had a backup of most, but not all of the files involved. Other than that I'm just curious how this happened and how I can prevent it next time. Thanks!

• Dumping active directory

  - by Nop at NaDa

  I work in the IT support department of a branch of a huge company. I have to take care of a database with all the users, computers, etc. I'm trying to find a way to automatically update the database as much as possible, but the IT infrastructure guys doesn't give me enough privileges to use Active Directory in order to dump the users, nor they have the time to give me the information that I need. Some days ago I found Active Directory explorer from Sysinternals that allows me to browse through Active Directory, and I found all the information that I need there (username, real name, date when it was created, privileges, company, etc.). Unfortunately I'm unable to export the data to a human readable format. I'm just able to take a snapshot of the whole database in a machine-readable format. Doing the snapshot takes hours and I'm afraid that the infrastructure guys won't like me doing entire snapshots on a regular basis. Do you know of any tool (command-line is preferable) that would allow me to retrieve the values of the keys or export it to XML, CSV, etc?

• Is there any functional-like unix shell?

  - by Caruccio

  I'm (really) newbie to functional programming (in fact only had contact with it using python) but seems to be a good approach for some list-intensive tasks in a shell environment. I'd love to do something like this: $ [ git clone $host/$repo for repo in repo1 repo2 repo3 ] Is there any Unix shell with these kind of feature? Or maybe some feature to allow easy shell access (commands, env/vars, readline, etc...) from within python (the idea is to use python's interactive interpreter as a replacement to bash). EDIT: Maybe a comparative example would clarify. Let's say I have a list composed of dir/file: $ FILES=( build/project.rpm build/project.src.rpm ) And I want to do a really simple task: copy all files to dist/ AND install it in the system (it's part of a build process): Using bash: $ cp ${files[*]} dist/ $ cd dist && rpm -Uvh $(for f in ${files[*]}; do basename $f; done)) Using a "pythonic shell" approach (caution: this is imaginary code): $ cp [ os.path.join('dist', os.path.basename(file)) for file in FILES ] 'dist' Can you see the difference ? THAT is what i'm talking about. How can not exits a shell with these kind of stuff build-in yet? It's a real pain to handle lists in shell, even its being a so common task: list of files, list of PIDs, list of everything. And a really, really, important point: using syntax/tools/features everybody already knows: sh and python. IPython seams to be on a good direction, but it's bloated: if var name starts with '$', it does this, if '$$' it does that. It's syntax is not "natural", so many rules and "workarounds" ([ ln.upper() for ln in !ls ] -- syntax error)

• postfix email gateway

  - by k-h

  I am setting up a postfix email gateway. It will not hold any mail but will accept email for my domain and forward it to another internal mailserver and relay mail out from the internal server. One of the main problems is that I am working on a live running system and this will be an upgrade so I am using a test domain which I will change at some point to the real domain. I tried various methods but found the simplest way (that worked) was to use a script to create an aliases file (from ldap entries). There are various problems with this method. The main one being that the entries can't be of the simple form [email protected] because the gateway doesn't know where to send them. They have to be of the form: [email protected]. What I would like doesn't seem hard but I can't get my head around the postfix documentation. There seem to be various ways but none of them seem to work. Most of the examples I have found on the web assume the mail is going to end up on the server. I want a list of users somewhere, preferably of the form: user1, user2, etc rather than [email protected] (I can easily generate this list) and I would like postfix to forward all email to example.com to a particular server: ie realmailserver.example.com. Can anyone suggest clues as to how I might do this?

• How can one restrict network activity to only the VPN on a Mac and prevent unsecured internet activity?

  - by John

  I'm using Mac OS and connect to a VPN to hide my location and IP (I have the 'send all traffic over VPN connection' box checked in teh Network system pref), I wish to remain anonymous and do not wish to reveal my actual IP, hence the VPN. I have a prefpan called pearportVPN that automatically connects me to my VPN when I get online. The problem is, when I connect to the internet using Airport (or other means) I have a few seconds of unsecured internet connection before my Mac logs onto my VPN. Therefore its only a matter of time before I inadvertently expose my real IP address in the few seconds it takes between when I connect to the internet and when I log onto my VPN. Is there any way I can block any traffic to and from my Mac that does not go through my VPN, so that nothing can connect unless I'm logged onto my VPN? I suspect I would need to find a third party app that would block all traffic except through the Server Address, perhaps Intego Virus Barrier X6 or little snitch, but I'm afraid I'm not sure which is right or how to configure them. Any help would be much appreciated. Thanks!

• Understanding ulimit -u

  - by tripleee

  I'd like to understand what's going on here. linvx$ ( ulimit -u 123; /bin/echo nst ) nst linvx$ ( ulimit -u 122; /bin/echo nst ) -bash: fork: Resource temporarily unavailable Terminated linvx$ ( ulimit -u 123; /bin/echo one; /bin/echo two; /bin/echo three ) one two three linvx$ ( ulimit -u 123; /bin/echo one & /bin/echo two & /bin/echo three ) -bash: fork: Resource temporarily unavailable Terminated one I speculate that the first 122 processes are consumed by Bash itself, and that the remaining ulimit governs how many concurrent processes I am allowed to have. The documentation is not very clear on this. Am I missing something? More importantly, for a real-world deployment, how can I know what sort of ulimit is realistic? It's a long-running daemon which spawns worker threads on demand, and reaps them when the load decreases. I've had it spin the server to its death a few times. The most important limit is probably memory, which I have now limited to 200M per process, but I'd like to figure out how I can enforce a limit on the number of children (the program does allow me to configure a maximum, but how do I know there are no bugs in that part of the code?)

• Is NFS capable of preserving order of operations?

  - by JustJeff

  I have a diskless host 'A', that has a directory NFS mounted on server 'B'. A process on A writes to two files F1 and F2 in that directory, and a process on B monitors these files for changes. Assume that B polls for changes faster than A is expected to make them. Process A seeks the head of the files, writes data, and flushes. Process B seeks the head of the files and does reads. Are there any guarantees about how the order of the changes performed by A will be detected at B? Specifically, if A alternately writes to one file, and then the other, is it reasonable to expect that B will notice alternating changes to F1 and F2? Or could B conceivably detect a series of changes on F1 and then a series on F2? I know there are a lot of assumptions embedded in the question. For instance, I am virtually certain that, even operating on just one file, if A performs 100 operations on the file, B may see a smaller number of changes that give the same result, due to NFS caching some of the actions on A before they are communicated to B. And of course there would be issues with concurrent file access even if NFS weren't involved and both the reading and the writing process were running on the same real file system. The reason I'm even putting the question up here is that it seems like most of the time, the setup described above does detect the changes at B in the same order they are made at A, but that occasionally some events come through in transposed order. So, is it worth trying to make this work? Is there some way to tune NFS to make it work, perhaps cache settings or something? Or is fine-grained behavior like this just too much expect from NFS?
