  • How does Subnetting Work?

    - by Kyle Brandt
    How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself. What is classless routing and why is class-based routing obsolete? If I have a network, how do I figure out how to split it up? If I am given a netmask, how do I know what the network Range is for it? Sometimes there is a slash followed by a number, what is that number? Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different? Someone mentioned something about knowing binary for this? What is NAT (Network Address Translation). Not looking for links to other sites (unless maybe you have one post with a bunch of good ones). I already know how to subnet, I just thought it would be nice if Server Fault had a generic subnetting answer.

  • What is the quickest and safest way to test new software and revert all changes, if needed?

    - by calbar
    I'm looking for Windows software that will allow me to quickly create a "checkpoint", do whatever I might need to do to my computer - install programs/drivers/updates, create/delete personal files, reboot the system multiple times, open questionable attachments - and then revert the entire system back to when the checkpoint was created. Essentially I want Windows Restore Points that save my personal files and partitions, too. It sounds like disk imaging might be the ticket, but creating them is much too slow and the restore process too involved... I'm hoping to sacrifice full disaster recovery for speed. Creating a checkpoint should be as close to one-click as possible, and rolling back should be a matter of selecting a restore point and rebooting. Ding! I'm familiar with Sandboxie, True Image Home "Try and Decide", Returnil, and a number of other "virtual system" apps that actively "catch" changes and allow you to commit or reject them. I'm not interested in these for a number of reasons - I prefer the "cut and dry" restore point approach. Finally, I'll note that I've just recently become aware of Comodo Time Machine. It sounds absolutely perfect, however, a quick skim through the user forums show more than a few horror stories of corrupted, unbootable systems. Any positive personal experience with the software to suppress my superstitions, or suggestions for more established alternatives would be greatly appreciated - Comodo Time Machine seems relatively new. Thanks for your help!

  • Apache and MySQL not working well after extending filesystem

    - by xtrimsky
    I had 4Gb on my /var (/dev/mapper/vg00-var) filesystem, and I wanted to extend it to 160Gb. I did it following this tutorial: http://faq.1and1.com/dedicated_servers/root_server/linux_admin_help/7.html Now I have 160: Filesystem Size Used Avail Use% Mounted on /dev/md1 4.0G 424M 3.6G 11% / /dev/mapper/vg00-usr 4.3G 1.4G 3.0G 32% /usr /dev/mapper/vg00-var 198G 6.5G 192G 4% /var /dev/mapper/vg00-home 4.3G 4.4M 4.3G 1% /home none 1.1G 0 1.1G 0% /tmp Now I have a problem, in order for Apache to work, each time I reboot, I need to also reboot apache: "apachectl -k restart" which is already terrible. I think this is because /var contains the htdocs The worst part is, mysql is not starting at all. Mysql has some files also in /var What have I done wrong ?? :( Thank you EDIT: Attaching /var/log/mysqld.log: 120602 11:17:44 InnoDB: Waiting for the background threads to start 120602 11:17:45 InnoDB: 1.1.8 started; log sequence number 8354009 120602 11:17:45 [ERROR] /usr/libexec/mysqld: unknown variable 'set-variable=local-infile=0' 120602 11:17:45 [ERROR] Aborting 120602 11:17:45 InnoDB: Starting shutdown... 120602 11:17:46 InnoDB: Shutdown completed; log sequence number 8354009 120602 11:17:46 [Note] /usr/libexec/mysqld: Shutdown complete 120602 11:17:46 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

  • Reusing slot numbers in Linux software RAID arrays

    - by thkala
    When a hard disk drive in one of my Linux machines failed, I took the opportunity to migrate from RAID5 to a 6-disk software RAID6 array. At the time of the migration I did not have all 6 drives - more specifically the fourth and fifth (slots 3 and 4) drives were already in use in the originating array, so I created the RAID6 array with a couple of missing devices. I now need to add those drives in those empty slots. Using mdadm --add does result in a proper RAID6 configuration, with one glitch - the new drives are placed in new slots, which results in this /proc/mdstat snippet: ... md0 : active raid6 sde1[7] sdd1[6] sda1[0] sdf1[5] sdc1[2] sdb1[1] 25185536 blocks super 1.0 level 6, 64k chunk, algorithm 2 [6/6] [UUUUUU] ... mdadm -E verifies that the actual slot numbers in the device superblocks are correct, yet the numbers shown in /proc/mdstat are still weird. I would like to fix this glitch, both to satisfy my inner perfectionist and to avoid any potential sources of future confusion in a crisis. Is there a way to specify which slot a new device should occupy in a RAID array? UPDATE: I have verified that the slot number persists in the component device superblock. For the version 1.0 superblocks that I am using that would be the dev_number field as defined in include/linux/raid/md_p.h of the Linux kernel source. I am now considering direct modification of said field to change the slot number - I don't suppose there is some standard way to manipulate the RAID superblock?

  • Can't Connect SQL server - process being used by another process. Conflict with IIS?

    - by shinya
    I'm having problem connecting to MS SQL Server (2012 Express) after accessing a database through IIS (web site).

  • Which twitter client can synchronize unread tweets?

    - by Tom Burger
    Right now I'm forced to read all the tweets in a single client on a single device (TweetDeck on my Android phone). If I would switch to another device and/or client, I would need to search for the last unread tweet, which is sometimes complicated (too many tweets). So, the question: Is there a client who can keep the status (read/unread) on tweets across multiple devices? My target systems would be now Android and MS Windows, but also Linux might be handy.

  • 7-Zip many files from different folders?

    - by mafutrct
    I would like to add a large number of files with different names from different folders to a single 7-Zip archive using 7za.exe. This should be simple, but it turned out to be a major pain. I created a file that contains the paths (7za a out.7z @list.txt), but once there are too many (~100) files, it fails. Apparently the content of the argument file is pushed onto the command line buffer [Edit: This was likely a misinformation on my part, either way it was not the reason], which is far too small (the number of files to add is more than one million). Splitting the process up by adding the files one by one is not feasible due to the way 7za works: When adding the next file, it creates a copy of the archive, adds the file to the copy and finally replaces the original. This is terribly slow once the archive gets to a couple 100 MB in size. So far I am using a combination of the two approaches by adding a dozen files each time in a loop, but it is an unreliable hack and still very slow. Is there a better way to do it? I tried to use 7-Zip wrapper DLLs (I'm a C# programmer), but none of them worked reliably and I was repeatedly suggested to just use 7za instead.

  • How to use the outcome of a formula as the value for Vlookup or another IF formula

    - by Steven
    Ok I will try to explain my issue effectively. I am making a GPA sheet in which the value out of 100 is computer in to a GPA value and then in to a letter. In cell N5 i have the value of all their grades (formula: =H3+H4+H5) Now in cell (j6) I have a formula which is giving them a number depending on the value calculated in N5 (Formula: =IF(AND(N5>=60,N5<=63.999),"2.0",IF(AND(N5>=64,N5<=66.999),"2.25",IF(AND(N5>=67,N5<=69.999),"2.4",IF(AND(N5>=70,N5<=73.999),"2.5",IF(AND(N5>=74,N5<=76.999),"2.75",IF(AND(N5>=77,N5<=79.999),"2.9",IF(AND(N5>=80,N5<=83.999),"3.0",IF(AND(N5>=84,N5<=86.999),"3.25",IF(AND(N5>=87,N5<=89.999),"3.4",IF(AND(N5>=90,N5<=93.999),"3.50",IF(AND(N5>=94,N5<=96.999),"3.75",IF(AND(N5>=97,N5<=100),"4",IF(AND(N5<=59.999),"0"))))))))))))) Still no problem... as the values I was looking for comes out (example 84.2 shows up as 3.25 as I wanted). However here comes the problem.... I have tried to use the outcome in J6 to do Vlookup or another if formula, however excel does not seem to recognize the value in J6. For example: =VLOOKUP(j6,B3:C15,2,FALSE)... this returns N/A however if I enter =VLOOKUP(3.25,B3:C15,2,FALSE) it gives me what im looking for. It seems that excel will not register the outcome of my formula as a number. What can I do please?

  • VMWare use of Gratuitous ARP REPLY

    - by trs80
    I have an ESXi cluster that hosts several Windows Server VMs and around 30 Windows workstation VMs. Packet captures show a high number of ARP replies of the form: -sender_ip: VM IP -sender_mac: VM virtual MAC -target_ip: 0.0.0.0 -target_mac: Switch interface MAC The specific addresses aren't really a concern -- they're all legitimate and we're not having any problems with communications (most of the questions surrounding GARP and VMWare have to do with ping issues, a problem we don't have). I'm looking for an explanation of the traffic pattern in an environment that functions as expected. So the question is why would I see a high number of unsolicited ARP replies? Is this a mechanism VMWare uses for some purpose? What is it? Is there an alternative? EDIT: Quick diagram: [esxi]--[switch vlan]--[inline IDS]--[fw]--(rest of network) The IDS is complaining about these unsolicited ARPs. Several IDS vendors trigger on ARP replies without a prior request, or for ARP replies that have a target IP of 0.0.0.0. The target MAC in these replies is the VLAN interface on the switch. Capture points: -The IDS grabs the offending packets -The FW can see the same ones -A VM on the ESXi host does not see these, although there is an ARP request for a specific IP on the ESXi host that has source_ip=0.0.0.0 and source_mac=[switch vlan interface]. I can't share the captures, unfortunately. Really I'm interested in finding out if this is normal for an ESXi deployment.

  • How to resolve 'No internet connectivity issues' with a Virtualised 2008 R2 Server using Forefront UAG

    - by user684589
    I have spent some considerable time reading up on as many possible blogs and articles as I can to help me solve why my VM (Running on Hyper-V) for DirectAccess has suddenly stopped being able to access the internet. The VM setup shares the same internet connection on which I have written and submitted this question so I know that the actual underlying internet connection is fully functional. Previous to last week the DirectAccess was fully functional and had no issues. This is a recent problem which was led up to by a number of consistent crashes on the DA machine when access was attempted. Upon reboot all seemed well until recently. I am not certain whether it is relevant, but previously to this I had a number of power issues where the entire VM host shutdown unexpectedly leaving around 8 VM's in a bad way. Upon restart, the UAG DirectAccess machine was unable to access its configuration service (although the service was started) but this seemed to relate to the Light-Weight Active Directory Service AD LDS which had a corrupted database. Having repaired this database, I restarted the service and could subsequently reconnect to the configuration service again. For good measure I re-bound the network adapters (virtualised through Hyper-V) and DirectAccess claimed to be all happy again. However as it stands my machine is still unable to access the internet showing the "No internet connectivity" exclamation mark for the external facing NIC. I have also tried removing the adapters, disabling, re-enabling and the problem persists. The intranet part of the VM CorpNet seems to be fully functional as before and I'm running out of ideas. Any input would be greatly appreciated. I am not an advanced Domain Administrator so please be gentle.

  • Understanding Microsoft Word Formatting Behavior. Does anyone?

    - by deemer
    This isn't a question about how to do something (well, not directly), but rather an inquiry to see if anyone understands why MS Word behaves the way it does with respect to formatting from a design perspective. This is also admittedly a rant about Word. This is a question that has plagued me, well, every time I open a document in Word, and covers a lot of individual topics, so I'll restrict the discussion here to two concrete behaviors that baffle me. 1) Backspacing over whitespace changes the format of preceding text. This seems to most often occur when the preceding text is a header or list number. The strangest thing about this is the new format of the changed text usually doesn't appear anywhere else in the document. 2) Numbered lists count almost at random. I am working on a document today where the list numbers count as follows: 1, 2, 2, 3, 3. The lettering in the sublists go like this 1: a, 2: a, 2: b c d, 3: e f g, 3: a. Clicking on each number or letter highlights the other numbers or letters that Word thinks it is related to, which are scattered around the document pretty heavily. Attempts to renumber the list have so far proven fruitless, as Word seems to maintain these associations through clipboard copies, etc. Why could this even happen?

  • Is it possible to trace someone using Google during an online exam?

    - by George
    I happen to be a professor at a reputed college. I want to design an online exam for over 1000 students via around 50 computers right after the vacation ends. Now the problem is that I have heard that many students use Google on a different tab to find answers when no invigilator is around. I want to know if there is a way to backtrace it after the exams via some kind of history or any other possible way. In our university there is a standard system. I am not good with computers but I will try to explain. Each computer uses mozilla to connect to a server centrally located via an IP. The students open it and enter a unique ID and password to start the exams. Many questions are jumbled and different groups of students give exam in a different time slot. Is there any way to trace it since I want to set an example for students so they won't cheat and give exams in an honest way. Additional details: Since the number of computers are less than the number of students, more than 10 students are going to use a single computer on a single day over a period of 10 hours. After this, if I check the history (and let's say someone even forgot to delete the history and I see it), will I able to figure out who among the 10 has done it? Moreover, is it even practical and feasible?

  • What is the "in-the-wire" size of a ethernet frame? 1518 or 1542?

    - by chrisapotek
    According to the table here, it says that MTU = 1500 bytes and that the payload part is 1500 - 42 bytes or 1458 bytes (<- this is actually wrong!). Now on top of that you have to add IPv4 and UDP headers, which are 28 bytes (20 IP + 8 UDP). That leaves my maximum possible application message to as 1430 bytes! But by looking for this number in the Internet I see 1472 instead. Am I doing this calculation wrong here? All I want to find out is the maximum application message I can send over the wire without the risk of fragmentation. It is definitely not 1500 because that includes the frame headers. Can someone help? The confusion is the the PAYLOAD can actually be as large as 1500 bytes and that's the MTU. So now what is the size in-the-wire for a payload of 1500? From that table it can be as big as 1542 bytes. So the maximum app messages I can send is 1472 (1500 - 20 (ip) - 8 (udp)) for a maximum in the wire size of 1542. It amazes me how things can get so complicated when they are actually simple. And I have not clue how someone came up with the number 1518 if the table says 1542.

  • Clicking far away in vim in tmux in urxvt

    - by paps
    I use vim inside tmux inside urxvt, and the mouse works perfectly well for clicking and selecting text, except when I want to click too far to the right. It seems to be related to the distance in number of columns from the left. When I go beyond column ~200 (not sure about the exact number), clicking simply does nothing. Note that it's not related to a vim window: with two vim windows taking ~150 columns each, clicking will not work after the ~50th column in the second window. It's related to the whole vim session. Also note that clicking far away in a big tmux pane (200 columns) works perfectly. In my .tmux.conf I have this line: set -g default-terminal "screen-256color" and in my .vimrc I have this: if &term =~ "^screen" autocmd VimEnter * silent !echo -ne "\033Ptmux;\033\033]12;7\007\033\\" let &t_SI = "\<Esc>Ptmux;\<Esc>\<Esc>]12;5\x7\<Esc>\\" let &t_EI = "\<Esc>Ptmux;\<Esc>\<Esc>]12;7\x7\<Esc>\\" autocmd VimLeave * silent !echo -ne "\033Ptmux;\033\033]12;14\007\033\\" end It changes the cursor's color depending on the editing mode of vim, and it works, meaning that tmux really sets $TERM to "screen-256color" — but I don't know if this has any relevance with my mouse problem. I'm running Ubuntu 12.04, vim 7.3, tmux 1.6 and rxvt-unicode 9.14. Does anybody have an idea about what is causing this problem? Thanks.

  • Siege - running a stress test benchmark

    - by morgoth84
    I need to do a benchmark test of a HTTPS server using Siege, to see how it behaves under massive load. I'm initiating tests from another machine which is quite powerful and it is connected to the same physical switch the server is connected on. But when I initiate a test, I can't get it to make more than 170 requests per second. With this load the server's CPU usage is at 15-20% and the average response time for a request is approx. 0.03 seconds. Load of the client machine is approx. at 10%. So, I gradually increase the number of users in Siege (the number of worker threads) and request rate linearly increases up to 170 reqs/sec, but it never gets over it. No matter how many more worker threads I start, the load on the server is never more than 20% (and the client's load also doesn't increase any more). How can I overcome this? I've googled a bit and found out that after a request is completed, a socket associated with one ephermal port remains in WAIT_TIME state for some time during which it can't be reused. I tried to overcome this by doing these things: sysctl -w net.ipv4.ip_local_port_range="1024 65535" echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle Oh, and the client machine is a Linux (RedHat, I think, but I'm not sure). Any help would be appreciated.
