  • Preventing applications from performing run once tasks for multiple users

    - by JohnyV
    In our environment we have several applications that are installed that have a need to run a little prompt the first time they run eg Media player, Google earth etc. The problem is we have many users on many different computers. And the computers have deepfreeze running on them which removes the users profile once the computer is restarted. So next time that user logs in they have to go through the whole thing of run once again. I have managed to prevent IE runonce using group policy and office run once from using the office customisation tool. Is there a way to make this happen for other applications. On windows xp we used to copy a user that has run all the apps and place their default profile into the default profile so that new users get that profile template. Now with windows 7 the process of copy profiles is not as easy. Is there an easy way to copy profiles in win 7 or is there a better way (eg modify reg or app data) to prevent apps from performing an initial run. Thanks

  • Nginx + WordPress + HHVM: Why isn't Batcache working? Would Varnish help even more?

    - by javipas
    I've heard great things about HHVM, so I've setup a copy of WordPress blog (on another domain) with Nginx (with the Pagespeed module) and HHVM. Right now the benefits are obvious: on the same config, load times are between two and three times faster. I'm trying to speed up things a little bit, and I've also installed Memcached and Batcache. I've installed the memcached package, copied object-cache.php (Pastebin) onto the root folder of the WordPress blog, and after that I've installed the Batcache plugin and copied the advanced-cache.php (Pastebin) file onto the wp-content folder. Also, I've included the line define('WP_CACHE', true); in the wp-config.php file. It seems it doesn't work, though. If I quickly reload the page several times Batcache should show the cached page, but it doesn't. It's easy to check that by reloading (Cmd+R on Chrome on OS X) the page several times and then viewing the page's code. Under the <head> section I should see some batcache stats, but they aren't there. I wonder if someone could give me some hint on this. On a side note, I don't know if I could add some other component in order to help the performance be even better. I'm thing about Varnish, but I'm not sure if it's just useless and it's just another way to the same I'm currently doing. Any other component there? (I'll test CDN for images, minifying js, etc and some other tricks as well, but I'm talking from the server perspective).

  • Datacentre Rack naming convention with flexibility for reassignment of server roles

    - by g18c
    We are just shifting across to a new rack and until now have used names of cartoon characters. This is not going to work anymore, and need a better naming convention. Physically i would like to name the servers by location, and then have an alias as to its actual function/customer, i.e. Physical name LONS1R1SVR1 meaning London, suite 1, rack 1, server 1 Customer Alias Since the servers can be reassigned from time to time, for the above physical server name, i would have an alias as a column in a spreadsheet, that would be set to the customers host-name, i.e. wwww.customerserver1.com Patching For patching, I am looking at labeling up the physically connections, i.e. LON1S1R1SVR1-PWR1 LON1S1R1SVR1-PWR2 LON1S1R1SVR1-ETH0 LON1S1R1SVR1-KVM Ultimately if i am labeling cables, I really want to avoid putting LON1S1R1SQLSVR on any patch cord in case the server gets formatted and changed from a SQL server to a WWW server which would need to relabel all the patch cords also. In addition, throwing in virtual machines, i have got confused very quickly. I appreciated that it may be confusing having a physical host-name and customer alias. Please let me know what you run with and any other standards or best practices that i can follow?

  • KVM Hosting: How to efficiently replicate guests

    - by javano
    I have three KVM servers each with 1 guest VM, running directly on it's local storage, (so they are essentially getting a dedicated box worth of computing power each). In the event of a host failure I would like the guests replicated to at least one of the other hosts so I can spin it up there, until the failing host is fixed. I am curious about KVM cloning. I can clone a VM live or when it's suspended/shutdown. Obivously suspended VMs will naturally be quicker to clone but these three VMs comprise three parts of a single solution, so I don't want to ever have any one of them shutdown. How can I efficiently clone these VMs between servers? I have had a couple of ideas, but are these insane or, is there a better method I have missed for my scenario? Set up a DRDB partition between box 1 and 2 where VM 1 runs from, and so is replicated between box1 and box 2, repeat between box 2 & 3, and box 3 & 1 (This could be insane, I have never used DRDB only read about it) Just use standard KVM CLI clone options to perform live clones (I'm dubious about this because I don't know how long it will take and what the performance impact will be during) Run a copy of each VM on at least one other host, and have the guest on one host export it's data to the matching guest on another host where it can import that data, scripting this on the guest) Some of other way? Ideas welcome! Side Note These servers have 4x15k SAS drives in a RAID 10 so they aren't rocketing fast, and as I mentioned, each VM runs from the host's local storage, no NAS or SAN etc. So that is why I am asking this question about guest replication. Also, this isn't about disaster recovery. Guests will be exporting their data to a NAS over a VPN, so I am looking at how I can have them quickly spun up in a host failure situation.

  • Connecting to unsecured wireless network

    - by Sanchez
    I would like to know what information is public and can be intercepted in a non-open, but unsecured wireless network. Moreover, is there anything I can do to make it more "secure", other than using https connection whenever possible. In more details, I recently discovered (with surprise) that the wireless network in my school is actually unsecured. Although not everyone can connect to it (you need a student ID), I am told that certain softwares like Wireshark would be able to intercept the data. Since I have been using the network for all private purposes (email, facebook etc), I do feel quite insecure now and would like to understand the situation a bit better. I installed Wireshark and tried to play with it but all I can see are something alien to me. In any case, all I see seems to come directly/indirectly from my IP address, and I have long thought that usually different computers in the same wireless network would be assigned different addresses. Am I wrong? If not, then I feel very confused about what information is actually being captured (potentially by other users in the network, since I don't think I could capture activities of others in the same network anyway), and whether it's safe to use the network at all. (Gambling on others in the same network showing good behaviour is apparently not an option.) Thank you.

  • CPU temperatures high on new build after gaming

    - by Reznor
    My friend had a problem with his computer a while back. His games were crashing, even within the menus. He was stumped as to what the problem was, so I posted on here requesting help. He found out the day later, when his computer would start up but wouldn't display anything on the screen. His video card must have came screwed up. So, he got a replacement. Now, there's a new problem. His temperatures, which were acceptable before, are now insanely high. His GPU temperature runs 70-80c, which is understandable considering he's running his games maxed out, but the real problem here is his processor and motherboard temperatures. All four of his cores are running at 88-90c after coming out of a game. His motherboard temperature was also 70c at one point. In terms of cooling, his case should definitely be adequate. He has an Antec Twelve Hundred. He's using stock fans. The cable management in his case is very good; better than average. He's using the stock heatsink with the processor too, but note, it was fine before the replacement, so it isn't like there's some inherent problem. He has checked the case too. Everything's fine! No cables in the way. The heatsink is seated properly. He turned his case fans up to high, as well, but the temperatures are persisting. Could the processor be overheating due to running games maxed out? Any ideas?

  • SWATCH - what am I doing wrong?

    - by Brian Dunbar
    What I want/need/desire is to log when a user logs into my FTP server. Problem: I can't make swatch work the way I should be able to. This data is logged to a file - but of course these logs are not kept very long. I can't keep the logs around forever, but I can extract data from then, analyze it, store results elsewhere. If there is a better way to do this than the following, I'm all ears. Swatch version 3.2.3 Perl 5.12 FTP: VSFTP OS (Test): OS X 10.6.8 OS (Production): Solaris From man I see I can pass contents to a command .. so I should be able to echo those values to file, do a sed/cut/uniq thing on them for stats. $ man swatch (snip) exec command Execute command.

  • sbs-server with 2 nics and 2 connections to the internet with different providers not working as it

    - by erik-van-gorp
    We have the following configuration : A sbs-2003 server in a domain (mydomain.com) with 2 network cards, each connected to a different network (provider), with different gateways, one for web and one for mail and clients. (we do this because the bandwitdh we get from our providers is too small to handle all the mail(+spam) traffic and webservices, so we took 2 providers) DNS is as follows : www.mydomain.com 1.2.3.4 mail.mydomain.com 5.6.7.8 NIC 1(192.168.1.3) is connected to to the internet through a firewall at 192.168.1.1, having wan address 1.2.3.4 NIC 2(10.0.0.3) is connected to to the internet through a firewall at 10.0.0.1, having wan address 5.6.7.8 Both nics have their default gateway installed at their corresponding routers. Also the metrics are set equal. (i know this isn't a supported config, but it works more or less). In this configuration i can use RDP on both wan adresses, and telnet to port 25 works as well on both. The issue now is that since a few weeks , we get regular disconnections, and website hickups(timeouts), several per hour. If we set one router to a higher metric, that route no longer works. In short, I want the mails to route through NIC2 and the web through NIC1. Any better configuration (without installing a second mail server) ?

  • Borked ubuntu uninstall - need to delete boot partition (i think)

    - by Max Williams
    I just got a new pc laptop with windows 7 and wanted to install Ubuntu on it. Which i did, no problem there, by downloading the installer, burning it to dvd then booting off the dvd and installing. Then, i realised that the new Ubuntu 12.04 uses the Unity desktop, which i immediately disliked, and after some research, began to hate. So, i decided (after a little googling) to install Linux Mint instead. So, thinking i'd better start from scratch, i went to the Windows 7 disk manager and wiped the Ubuntu partition that had been created. Now, when i start up, i get an error from grub, the ubuntu boot manager: error: unknown filesystem grub rescue> _ and a blinking cursor where i can enter commands. I suspect that what i've done is deleted the main ubuntu partition but NOT deleted another partition which is a boot partition, or something like that? Can anyone tell me how i can rescue or unbork this? I'd like to either a) get back to my original windows-only setup OR b) install linux mint off dvd (which i have), into the empty partition, fixing any grub confusion in the process. Any suggestions? Thanks, max BTW please don't answer if you're just going to tell me to stick with 12.04, or install a different distro or something. I definitely want Mint and just want to fix this mess - thanks :)

  • Log shipping on select tables.

    - by Scott Chamberlain
    I know I am most likely using incorrect terminology so please correct me if I use the wrong terms so I can search better. We have a very large database at a client's site and we would like to have up to date copies of some of the tables sent across the internet to our servers at our office. We would like to only copy a few of the tables because the bandwidth requirement to do log shipping of the entire database (our current solution) is too high. Also replication directly to our servers is out of the question as our servers are not accessible from the internet and management does not want to do replication (more on that later). One possible Idea we had is to do some form of replication on the tables we need to another database on the same server and do log shipping of that second smaller database but management is concerned that the clients have broken replication (it was between two servers on their internal network however) on us in the past and would like to stay away from it if possible. Any recommendations would be greatly appreciated. If using some form of replication is the only solution, I am not against replication, I just need compelling arguments to convince management to do it. This is to be set up on multiple sites that are running either Sql2005 or Sql2008 we will have both versions on our end to restore the data to so that is not a issue. Thank you.

  • keyboard intermittently stops working, even after reinstalling windows 7; possibly a Chrome issue?

    - by neverskipbreakfast
    My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash a couple of the ctrl+alt+windows type keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu, but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) *Unplugging & reconnecting keyboard does NOT fix it. *Connecting a different keyboard does NOT fix it. That one won't work, either. *Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. *Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears, they keyboard won't work, and neither will the icon to pull up the on-screen keyboard. Otherwise my mouse can click around just fine. I can only log onto a non-password protected account. *Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. *Clearing my Chrome browsing data stopped the problem from recurring for a week or so. *I use Avira free antivirus software, and repeated scans turn up nothing fishy. *I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. The only thing I suspect is something in Google Chrome -- I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?

  • Is there any way to limit the turbo boost speed / intensity on i7 lap?

    - by Anonymous
    I've just got a used i7 laptop, one of these overheating pavilions from HP with quad cores. And I really want to find a compromise between the temp and performance. If I use linpack, or some other heavy benchmark, the temp easily gets to 95+, and having a TJ of 100 Degrees, for a 2630QM model, it really gets me throttling, that no cooling pad or even an industrial fan could solve. I figured later that it is due to turbo boost, and if I set my power settings to use 99% of the CPU instead of 100%, and it seems to disable the turbo boost, so the temp gets better. But then again it loses quite a bit of performance. The regular clock is 2GHz, and in turbo boost it gets to 2.6Ghz, but I just wonder if I could limit it to around 2.3Ghz, that would be a real nice thing. Also there is another question I've hard time getting answer to. It seems to me that clocks are very quickly boosting up to max even when not needed, eg, it's ok if the CPU has 0% load, the clocks get to their 800MHz, but even if it gets to about 5% it quickly jumps to a max and even popping up turbo, which seems very strange to me. So I wonder if there is any way to adjust the sensitivity of the Speed Step feature. I believe it would be more logical to demand increased clock if it hits let's say 50% load. I do understand that most of these features are probably hardwired somewhere in the CPU itself or the MB, which has no tuning options just like on many laptops. But I would appreciate if you could recommend some thing, or some software. Thanks

  • RAID 6 that can read with least 1000 Mbit/s?

    - by Diblo Dk
    I purchased a Dell PERC 6/i which I expected to be able to read with 1000 Mbps. There is not much to do now, but there are some things I wanted knowledge about for another time. I have configured it with four 2 TByte drives and RAID 6. It have 256 MByt ram and transfer rate of 300 Mbps. The benchmark test showed: Min read rate: 136.3 Mbps Max read rate: 329,6 Mbps Avg read rate: 242,2 Mbps What could I had done to get at least 1000 Mbps? Is it normal for internal and external RAID controllers to have a lower transfer rate eg. 300 Mbps? (I did not noticed at the time that it was not 3 Gbps) How would a RAID 10 had performed compared to RAID 6 or 5? Would it have been better to use software RAID (Linux) with the internal 3 Gbps SATA controller? UPDATE: The drives is SATA III 6 Gbps. http://www.seagate.com/files/staticfiles/docs/pdf/datasheet/disc/desktop-hdd-data-sheet-ds1770-1-1212us.pdf (2TB)

  • configure a Macbook Pro to use external monitor at boot (Debian Linux)

    - by Eric
    In the spirit of reuse, I've installed Debian (version 6.0.5 "squeeze") on my wife’s old Macbook Pro (circa 2009 or so), to repurpose it for various tasks. The catch is the display is flaky. It will last a random amount of time, between 2 minutes and 2 hours, before freezing and graying out. This is a known issue with that generation of MBP. Fortunately it’s no problem for me, as I plan to use it with an external monitor anyway. Which brings us to the problem: How do I configure this thing to output to the external display by default, and hopefully disable the built-in LCD? The ideal solution would be to modify a setting in the EFI (BIOS), but I’m not holding out much hope for that. Next best thing would be a kernel option I can pass to the NVIDIA driver. What won’t work is a solution that doesn’t give me a display until X starts. I need to have console access, especially given that the built-in LCD is dying, and any day now might give out completely. So far I haven’t been able to find anything online. lspci says I’ve got an NVIDIA GeForce 9400M Help is much appreciated! Eric PS if this question is better suited to the Unix & Linux area, pls advise and I will move it.

  • how to set up dual wireless routers (G and N) with single broadband connection

    - by user15973
    A local cafe has an 802.11g wireless router attached to either an 8- or 12Mbs broadband connection. Although many customers still have -g devices, an increasing number are showing up with 802.11n devices (e.g. Mac laptops, iPads). The cafe owner is content with his router's area coverage, but he would like for his customers to be able to take advantage of the higher -n download speeds. He could simply replace the -g router with a -n router, but reportedly -n routers slow down considerably when servicing both -g and -n connections. Another option would be to buy the -n router, run an Ethernet cable between the two routers, and (of course) hook up the broadband connection to one of the two routers. Still another option would be to attach an ordinary, wired switch to the broadband connection and then attach both routers to the switch. Aside from the cost issue, what are the tradeoffs of those approaches? Which would you recommend, and why? Is there a better option than the ones I mentioned? Thank you in advance for your advice.

  • Is Hyper-V server suitable as a desktop testbench?

    - by Thomas.Winsnes
    At the moment we are running a test bench with several desktop computers, that are reimaged every time we need to test on a different operation system. Also because different versions of our software is tested on each image, we have to install our software every time we want to test it. The problem we have had with going with a virtualization technology is that our software is depending on directx/opengl and 3D acceleration, and this has not been something that virtual machines have excelled at. With the release of SP1 for Windows 7 and Server 2008 R2 Hyper-V has gotten better 3D acceleration support, so we are looking into virtualizing our testbench using this. Our test scenario would most likely be something close to this: 1. Remote into the hyper-V server and load the test VM needed for the current tests 2. Remote into the VM and install the new version of the software 3. Run the tests It would be nice, but not essential, if our support team could remote into the VMs to match the users OS+software combination when doing support. Does anyone have any experience with this kind of settup with hyper-v?

  • Logitech Performance MX Mouse Jumps on OS X Lion (10.7.4)

    - by Adam Thompson
    I have a Logitech MX Revolution wireless mouse that I am trying to use with OS X Lion. Everything is working except for one problem... there is a small, but quite noticeable, jump when the mouse cursor is moved. The problem is mostly prevalent when dragging and dropping files or trying to highlight items. It makes performing any task with the mouse accurately next to impossible. I did quite a bit of looking and found that all kinds of people have had mouse issues with OS X. I've tried all of the following with absolutely no success: Using the official drivers from Logitech (these performed worse than the default mouse drivers in OS X) Using SteerMouse as a third party mouse driver. This worked ever so slightly better than the default driver, but still suffered quite frequently from the skipping problem Cleaning the sensor on the mouse and ensuring it's not the result of the surface that it's being used on. Tested the mouse on a Windows machine. The mouse worked absolutely flawlessly on the other machine. Changed the channel that my wireless router operates on by the off chance my problems were the result of interference. This also had no effect. I can't think of anything else that could possibly interfere with the mouse. I'm am out of ideas on what to try, so I would really appreciate if anyone has any suggestions. I should also mention that an old wired mouse I had laying around worked just fine when I plugged it in. This really isn't the best solution, however, as I really prefer the MX Revolution.

  • OpenVPN-based VPN server on same system it's "protecting": feasible?

    - by Johnny Utahh
    Scenario: hosted machine (typically a VPS) serving wiki, svn, git, forums, email lists (eg: GNU mailman), Bugzilla (etc) privately to < 20 people. People not on team not allowed access. Seeking VPN-restricted access to said server. Have good user experience with OpenVPN-based servers/clients, but have yet to server-admin such systems. Otherwise, experienced Linux sysadmin. Target system: Ubuntu, probably 12.04. Seeking to put an OpenVPN process on above server to "protect" all the above-mentioned services, enabling only OpenVPN-authorized clients/processes to access above services. (Can easily acquire additional IP address(es) as needed for this setup.) Option: if absolutely needed, can employ an additional, dedicated, "VPN server" VPS simply to be my VPN server "front end." But prefer to have all server processes (VPN server plus other server apps) all running on same machine, if possible. Will consider further if dedicated-VPN-machine setup enables 1. easier installation/administration, 2. better/easier end-user experience, and/or 3. makes system significantly more secure. Any of above feasible? The main intention: create a VPN from purely-hosted resources, and not spend all the effort to make a non-VPN, secure site--which typically means "SSL wrapping" + all the continual webserver-application-update management. Let the VPN server deal with access security, and spend list time pushing said security "down" in the other apps/Apache.

  • MX records set up

    - by andrei.troll
    I just want to know how other people set up their MX-entries for mail accounts used with google apps. I work at a local web-hosting firm and we get a lot of tickets from clients who want to set up these settings. I just set them up something like: example.com. 14400 IN MX 10 ALT1.ASPMX.L.GOOGLE.COM. example.com. 14400 IN MX 10 ASPMX4.GOOGLEMAIL.COM. example.com. 14400 IN MX 15 ASPMX5.GOOGLEMAIL.COM. example.com. 14400 IN MX 15 ASPMX2.GOOGLEMAIL.COM. example.com. 14400 IN MX 30 ASPMX3.GOOGLEMAIL.COM. I see another firm (rival one) who sets up way more MX-records ? Roughly, around 10-15 entries. Am I doing something wrong ? More is better in this case ? Is there a secret that I'm not on too ?

  • Formula-based Excel page headers

    - by Jake Krohn
    I'm using the "Rows to repeat at top" function in Excel's "Page Setup" dialog to ensure that a multi-row header block appears on every printed page of my worksheet. However, I'd like to be able to change certain bits of the header based on the content of the current page. I would simply like to display the value of one cell in the first row that is printed on the page. If this is my header: Section: xx And the data looks like this (columns are Section and Name): 1 Foo 1 Bar 2 Baz I want the "xx" in the header to be "1". If, further down on the next page, the value in the Section column is "3", I want that printed in the header of the next page. I originally thought that using the "OFFSET" function might help, e.g. ="Section: "&OFFSET(A2, 1, 0) But it only shows the offset from the original placement of the header, thus only working on page 1. The end document is a PDF, so right now I'm able to go back in with the "TouchUp Text Tool" in Acrobat and add the numbers page by page. But it gets to be a tedious process with 70+ page reports. Anyone have any better ideas that don't require me mucking up the original Excel document with inserted headers every N lines? This is Excel 2008 for Mac, if it makes a difference.

  • Test script if host is back online

    - by brubelsabs
    E.g. system: Ubuntu/Debian. As many of you do this probably via ping and a terminal, I always forget this terminal when switching to other task... So a noftification popup would be useful. So can I do better as this?: while; do if ping -c 1 your.host.com; expr $? = 0; then notify-send "your.host.com back online"; sleep 30s; else sleep 30s; fi; done You will need zsh and libnotify to let the snippet work. As script: #!/usr/bin/env zsh while; do if ping -c 1 $1; expr $? = 0; then notify-send "$1 back online"; sleep 30s; else sleep 30s; fi; done

  • IP tables blocking access to most hosts but some accesses being logged

    - by epo
    What am I getting wrong? A while back I locked down my web hosting service while hardening it or at least trying to. Apache listens on port 80 only and I set up iptables using the following: IPS="list of IPs" iptables --new-chain webtest # Accept all established connections iptables -A INPUT --protocol tcp --dport 80 --jump webtest iptables -A INPUT --match state --state ESTABLISHED,RELATED --jump ACCEPT iptables -A webtest --match state --state ESTABLISHED,RELATED --jump ACCEPT for ip in $IPS; do iptables -A webtest --match state --state NEW --source $ip --jump ACCEPT done iptables -A webtest --jump DROP However looking at my apache logs I notice various log entries in access_log, e.g. 221.192.199.35 - - [16/May/2010:13:04:31 +0100] "GET http://www.wantsfly.com/prx2.php?hash=926DE27C156B40E55E4CFC8F005053E2D81E6D688AF0 HTTP/1.0" 404 206 "-" "Mozilla/ 4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 201.228.144.124 - - [16/May/2010:11:54:16 +0100] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 226 "-" "-" 207.46.195.224 - - [16/May/2010:04:06:48 +0100] "GET /robots.txt HTTP/1.1" 200 311 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)" How are these slipping through? I don't mind the indexing bots (though I am a little surprised to see them get through). I suppose they must be getting through using the ESTABLISHED,RELATED rules. And no, I can't for the life of me remember why the first match state rule is there So 2 questions: is there a better way to set up iptables to restrict access to specified hosts? How exactly are these 3 examples slipping through?

  • Setting up ssh config file with id_rsa through tunnel

    - by Rubens
    I've been struggling to set up a valid configuration to open a connection with a second machine, passing through another one, and using an id_rsa (which requests me a password) to connect to the third machine. I've asked this question in another forum, but I've received no answer that could be considered very helpful. The problem, better described, goes as follows: Local machine: user1@localhost Intermediary machine: user1@inter Remote target: user2@final I'm able to do the entire connection using pseudo-tty: ssh -t inter ssh user2@final (this will ask me the password for the id_rsa file I have in machine "inter") However, for speeding things up, I'd like to set my .ssh/config file, so that I can simply connect to machine "final" using: ssh final What I've got so far -- which does not work -- is, in my .ssh/config file: Host inter User user1 HostName inter.com IdentityFile ~/.ssh/id_rsa Host final User user2 HostName final.com IdentityFile ~/.ssh/id_rsa_2 ProxyCommand ssh inter nc %h %p The id_rsa file is used to connect to the middle machine (this requires me no password typing), and id_rsa_2 file is used to connect to machine "final" (this one requests a password). I've tried mixing up some LocalForward and/or RemoteForward fields, and putting the id_rsa files in both first and second machines, but I could not seem to succeed with no configuration whatsoever. Hope somebody can help me here! Regards! P.S.: the thread I've tried to get some help from: http://www.linuxquestions.org/questions/linux-general-1/proxycommand-on-ssh-config-file-4175433750/
