  • Calculate geometric mean in Excel

    - by Libby
    I have some email network data in Excel as a edgelist meaning I have columns Vertex1, Vertex2, and then N columns of properties of that edge like how many emails were sent from one person to another. For each row in the data, Vertex1 is the source of a message, and Vertex2 is the target, so edges are directed. Here's some sample data Vertex1 Vertex2 nMessages Bob Cindy 12 Cindy Bob 3 Bob Mike 11 Cindy Mike 1 I'm trying to calculate a geometric mean of the form gm = sqrt[(# of edges ij)*(# of edges ji)] So gm for Bob and Cindy is gm = sqrt[(messages from Bob to Cindy)*(messages from Cindy to Bob)] or sqrt(12*3) = 6. Is there a way to make that a formula in Excel?

  • RFC 1918 address on open internet?

    - by longneck
    In trying to diagnose a failover problem with my Cisco ASA 5520 firewalls, I ran a traceroute to www.btfl.com and, much to my surprise, some of the hops came back as RFC 1918 addresses. Just to be clear, this host is not behind my firewall and there is no VPN involved. I have to connect across the open internet to get there. How/why is this possible? asa# traceroute www.btfl.com Tracing the route to 157.56.176.94 1 <redacted> 2 <redacted> 3 <redacted> 4 <redacted> 5 nap-edge-04.inet.qwest.net (67.14.29.170) 0 msec 10 msec 10 msec 6 65.122.166.30 0 msec 0 msec 10 msec 7 207.46.34.23 10 msec 0 msec 10 msec 8 * * * 9 207.46.37.235 30 msec 30 msec 50 msec 10 10.22.112.221 30 msec 10.22.112.219 30 msec 10.22.112.223 30 msec 11 10.175.9.193 30 msec 30 msec 10.175.9.67 30 msec 12 100.94.68.79 40 msec 100.94.70.79 30 msec 100.94.71.73 30 msec 13 100.94.80.39 30 msec 100.94.80.205 40 msec 100.94.80.137 40 msec 14 10.215.80.2 30 msec 10.215.68.16 30 msec 10.175.244.2 30 msec 15 * * * 16 * * * 17 * * * and it does the same thing from my FiOS connection at home: C:\>tracert www.btfl.com Tracing route to www.btfl.com [157.56.176.94] over a maximum of 30 hops: 1 1 ms <1 ms <1 ms myrouter.home [192.168.1.1] 2 8 ms 7 ms 8 ms <redacted> 3 10 ms 13 ms 11 ms <redacted> 4 12 ms 10 ms 10 ms ae2-0.TPA01-BB-RTR2.verizon-gni.net [130.81.199.82] 5 16 ms 16 ms 15 ms 0.ae4.XL2.MIA19.ALTER.NET [152.63.8.117] 6 14 ms 16 ms 16 ms 0.xe-11-0-0.GW1.MIA19.ALTER.NET [152.63.85.94] 7 19 ms 16 ms 16 ms microsoft-gw.customer.alter.net [63.65.188.170] 8 27 ms 33 ms * ge-5-3-0-0.ash-64cb-1a.ntwk.msn.net [207.46.46.177] 9 * * * Request timed out. 10 44 ms 43 ms 43 ms 207.46.37.235 11 42 ms 41 ms 40 ms 10.22.112.225 12 42 ms 43 ms 43 ms 10.175.9.1 13 42 ms 41 ms 42 ms 100.94.68.79 14 40 ms 40 ms 41 ms 100.94.80.193 15 * * * Request timed out.

  • With CentOS 6 and LXC, "ifconfig" is unable to see network interface (but busybox "ifconfig" works fine)

    - by larsks
    I've just started working with LXC under CentOS 6 (via the libvirt adapter). If I create an LXC container, I'm unable to see any network interfaces when using the native system tools: # ifconfig -a # The behavior is very odd; specifying an interface by names yields neither the expected output nor an error message. This is true even for clearly invalid interface names, like this: # ifconfig foo # The ip command exhibits the same behavior. On the other hand, if I use "ifconfig" provided by busybox, everything works as expected: # busybox ifconfig -a eth0 Link encap:Ethernet HWaddr 52:54:00:E0:12:C8 inet6 addr: fe80::5054:ff:fee0:12c8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:268 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17814 (17.3 KiB) TX bytes:552 (552.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) So...what does busybox know that the native tools don't? The libvirt config for this environment is pretty standard; the network definition looks like this: <interface type='network'> <mac address='52:54:00:e0:12:c8'/> <source network='default'/> <target dev='veth0'/> </interface> The full configuration is here if you think it might help. I'm running: lxc-0.7.2-2.el6.x86_64 kernel-2.6.32-71.29.1.el6.x86_64 EDIT Weirder and weirder...it's a display issue, not a functionality issue. I can see the output of ifconfig if I pipe it into anything, so for example: # ifconfig eth0 | cat eth0 Link encap:Ethernet HWaddr 52:54:00:E0:12:C8 inet addr:192.168.10.10 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fee0:12c8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:573 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:37914 (37.0 KiB) TX bytes:552 (552.0 b) And in fact even when not piping the output, strace shows that ifconfig is in fact writing the output to file descriptor 1 (aka stdout), so it's not clear why no output is actually showing up. This could be either an LXC or a virsh issue, I guess.

  • Kickstart installation: Unable to read package metadata.

    - by yacov
    I'm trying to install a CentOS OS with kickstart using HTTP as the installation source. The kickstart server and the installed server are both running on VMs on the same machine. after the anaconda system installer starts it fails with the following message: I tried installing two different versions of Centos(5.5 and 5.2), and they both pass a CDROM media test the manual installation provides. The only errors on the kickstart server side are some errors in the httpd log I consider irrelevant: [Sat Mar 12 23:25:19 2011] [error] [client 192.168.1.112] File does not exist: /tftpboot/linux-install/platforms/CentOS5.5/images/product.img [Sat Mar 12 23:25:19 2011] [error] [client 192.168.1.112] File does not exist: /tftpboot/linux-install/platforms/CentOS5.5/disc1 I tried searching the internet for days and haven't found any solution... Does anyone have any idea?

  • How to set the subversion repository root in Debian?

    - by Andrew Whitehouse
    I have just switched from an old Fedora Core server to Debian Linux v5.0.4. Having migrated the old repository and configured access through svn+ssh, I now want to be able to access the repository with the same path on the client as before. On Fedora you could specify the repository root with "svnserve -r " but having checked the config files and svnadmin options I'm stuck as to how I can do this on Debian. Is there a way to set the repository root in Debian?

  • Location Services are always disabled in Mac OS X Lion

    - by rplusg
    A simple location services program was working fine on my machine and suddenly stopped working. Upon further exploring the problem, I realized that some process has disabled location services in System Preferences » Security & Privacy » Privacy. I checked Enable Location Services, but again it got disabled automatically. After some research I found that it's not just my program, even built-in system functions are also failing because of this problem for example System Preferences » Date & Time » Time Zone failed to get the current location. Every time I check Enable Location Services, I see the following error in the console logs: 16/10/12 11:23:15.636 AM [0x0-0x42042].com.apple.systempreferences: ERROR,Time,372059595.636,Function,"CLInternalSetLocationServicesEnabled",CLInternalSetLocationServicesEnabled failed 16/10/12 11:23:15.638 AM [0x0-0x42042].com.apple.systempreferences: STACK,Time,372059595.636,1 CoreLocation 0x00007fff8f9957be CLInternalSetLocationServicesEnabled + 110 Notes: WiFi is on I didn't install iOS Simulator I use Xcode Version 4.5 (4G182) I use Boot Camp and made my MacBook Pro dual boot (Mac OS X Lion and Windows 7) I do only Mac development but not iOS

  • MD3200i Slow Performance and Queue Depth

    - by Caleb_S
    Read performance on our SAN is slow under certain workloads. When we compare this to some local storage, we find the local storage performing 2x as fast. The SAN performs well with a high Queue Depth, and poorly with a low queue depth. However, the local storage performs well with a low Queue Depth. I'd like to know the reason for this occurring and find out what the specific limiting factor is in this situation. MD3200i iSCSI SAN ($15,000) 6 x 600GB 15k SAS RAID5 6 x 2TB 7.2k NLS RAID5 XCOPY /j Benchmark: (Slow) 15k Array - 71MB/s (Queue Depth 1) 7.2k Array- 71MB/s (Queue Depth 1) Robycopy /MT:32 Benchmark: (Fast) 15k Array - 171MB/s (Queue Depth ~12) 7.2k Array- 128MB/s (Queue Depth ~12) , , Read Performance on a Local controller is fast under the workload the SAN is slow at. , HighPoint 2230 RAID Controller ($600) 4 x 1TB 7.2k SATA RAID5 XCOPY /j Benchmark: 7.2k Array - 145MB/s (Queue Depth 1) (appears to max out the SATA bus)

  • Multi Gateway and Backup Routing on a cisco router

    - by user64880
    Hi all, I have a 2611 Cisco Router with only one Fastethernet port Now I have two internet gateways. I want to config my router as when primary routing fails second routing automatically start to route all my packets. When I set 2 IP route command in my router then I check I see it work well but when peer IP on primary routing is down it can not change to second routing until I remove first route command.In the following I write my setting. How can I set it? interface FastEthernet0/0 ip address 81.12.21.100 255.255.255.248 secondary ip address 62.220.97.14 255.255.255.252 ip route 0.0.0.0 0.0.0.0 62.220.97.13 ip route 0.0.0.0 0.0.0.0 81.12.21.97 100 Cheer, Kamal

  • Stop Munin messages from /var/log/syslog

    - by Sparsh Gupta
    Hello I am using munin on a system which is adding a log entry in syslog everytime the munin-node cron job executes. It is not an issue but it sometimes makes other errors spotting difficult. There are entries like Feb 28 07:05:01 li235-57 CRON[2634]: (root) CMD (if [ -x /etc/munin/plugins/apt_all ]; then /etc/munin/plugins/apt_all update 7200 12 >/dev/null; elif [ -x /etc/munin/plugins/apt ]; then /etc/munin/plugins/apt update 7200 12 >/dev/null; fi) every 5 minutes and I was wondering how can I stop the messages going into syslog. For munin specific errors I anyways have to keep an eye on /var/log/munin/* Thanks Sparsh

  • For Loop counting from 1 to n in a windows bat script

    - by raoulsson
    I need to run a windows command n times within a bat script file. I know how to do this in various programming languages but cannot manage to get it right on the windows command line :-( I would expect something like either for(int i = 0; i < 100; i++) { // do something } or even this (though not entirely seriously) 1.upto(100, { // do something }) Thanks! EDIT I can write a program in java, perl, c or whatever that will generate a bat script that looks like this for %%N in (1 2 3 4 5 6 7 8 9 10 11 12) do echo %%N and so on. Or even "better": echo 1 echo 2 echo 3 echo 4 echo 5 echo 6 echo 7 echo 8 echo 9 echo 10 echo 11 echo 12 and then execute it... But the thing is that I need a concise way to specify a range of numbers to iterate through within the script. Thanks!

  • Favorite Linux Variety and why?

    - by Cenoc
    Right now I have Fedora dual booted with Windows 7. The reasoning behind that is just because windows was the first OS I ever used and has some essential software, and Fedora is the first linux distribution I tried, but I would like to hear the argument for other distros, as I may be looking to switch. Thanks ahead of time.

  • Reasons for missing IP info in `last` output on pts logins?

    - by Mike Pennington
    I have five CentOS 6 linux systems at work, and encountered a rather strange issue that only seems to happen with my userid across all the linux systems I have...

Mon Nov 12 14:41 - 14:46 (00:04) You can see two of my pts login entries above that do not have a source IP address associated with them. My CentOS machines have as many as six other users that share the systems, but the mpenning userid is the only one that has this issue. Approximately 5% of my logins see this issue, but no other usernames exhibit this behavior. Questions Given the kind of scripts I keep on these systems (which control much of our network infrastructure), I'm a little spooked by this and would like to understand what would cause my logins to occasionally miss source addresses. Is there anything (other than malicious activity) that would reasonably explain the behavior? Other than bash history timestamping, are there other things I can do to track the issue down? Informational Since this started happening, I enabled bash history time-stamping (i.e. HISTTIMEFORMAT="%y-%m-%d %T " in .bash_profile) and also added a few other bash history hacks; however, that does not give clues to what happened during the previous occurrences. All the systems run CentOS 6.3...

  • tmux: unbind C-[ as a prefix

    - by StanAngeloff
    I have a fairly straight forward .tmux.conf file which does nothing more but to define a couple of options, such as history-limit. I have not added any custom key bindings yet. I find it extremely annoying that I cannot unbind C-[ as a prefix in tmux. Here is what I mean: $ uname -a Linux stan-inspiron 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ tmux [0] 0:~* "stan-inspiron" 10:05 12-Jun-12 % vim Whilst inside vim, when I go to insert mode and then use C-[0 to escape insert mode and move to the first character on the line, tmux grabs the key first and complains: Window not found: :0 ** I tried all sorts of things in my .tmux.conf, but nothing works. I thought it might be a terminal or shell issue, but confirmed same behaviour on a configless machine using Bash and [Gnome] Terminal. So the question really is, how do I unbind the C-[ key from tmux? ** I have base-index 1 set.

  • Areca 1880ix RAID hangs

    - by Dave
    Areca RAID controller ARC-1880ix-12 (firmware 1.50) hangs when on high load. My setup is: Chenbro 3U chassis Intel S5500BC mainboard Xeon 5603 CPU 16GB of RAM 12 Seagate SAS drives ST32000645SS (2 of them as hot spare, 10 as RAID10) Mellanox Infiniband HBA card This server is working as external infiniband storage for Xen VMs. When load is quite big Areca's firmware hangs - it becomes unreachable even from Areca's ethernet adapter. After resetting the server power it returns to normal operation. While Areca is hanged I can confirm that it is powered (ethernet link is active) and Infiniband HBA works Ok. Thanks in advance for any idea or suggestion where the problem might be!

  • Routing all data through an VPN tunnel with ppp

    - by Oliver
    I'm trying to create a VPN tunnel that forwards all data from the local machine to the VPN server. I'm using ppp-2.4.5 for this with the following configuration: pty "pptp <VPNServer> --nolaunchpppd" name <my login name> remotename PPTP usepeerdns require-mppe-128 file /etc/ppp/options.pptp persist maxfail 0 holdoff 5 I have a script in if-up.d with the following content: route del default eth0 route add default dev ppp0 Before starting the VPN tunnel my routing looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 2 0 0 eth0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 After starting the tunnel (via pon) it looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 12.34.56.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 Now the problem is, that the VPN tunnel seems to be looped into itself.

  • Error sending email to alias with Postfix

    I'm on Ubuntu 11.04 64bit. I'm trying to set up Postfix on my VPS, which has been configured but when I send an email to an alias e.g. [email protected] it will send it to [email protected]. Now when I sent the email from my GMail account, I got this returned: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain.

  • How to display recently installed programs and when they were installed?

    - by salvationishere
    I have a Windows XP and I just installed about 12 new programs. Big mistake! Before I installed these programs, my internet connection was running great. But now after installing and restarting my laptop, the internet is crawling. How can I see what was changed? Hint: prior to installing these 12 programs, I installed IE version 8. So probably if I removed that it would fix it, but the problem is I need IE in order for my SQL/C# web application to work properly.

  • Rename multiple files as "Modified Date/Time" using cmd or Powershell

    - by Mehper C. Palavuzlar
    I have hundreds of JPG files in a folder. I want to rename each file so that the file name is replaced with "Modified Date/Time" of that file, namely DD.MM.RRRR.HH.MM.jpg. For example, Before After 001.jpg 11.01.2011.16.58.jpg 002.jpg 12.01.2011.09.32.jpg 003.jpg 14.01.2011.12.41.jpg ... ... Since colon (:) cannot be used in file names, the colon between HH and MM must be replaced with a period. I don't want to use a 3rd party tool. Can you provide me with the code to achieve this in Powershell or command line?

  • Why am I getting 'undefined method' exceptions when executing 'run_list add', 'run_list remove' and 'rackspace server delete'?

    - by Peter Groves
    [Originally posted this to opscode forum, got no response] I’m testing out a free hosted chef-server account and multiple subcommands are failing with ‘Unexpected Errors’. Perhaps my version and the server version are incompatible? OS: Ubuntu 12.04LTS Local Chef: 10.12.0 (Installed through gem) Local Ruby: 1.8.7 Also, the workstation machine has been manually configured, but the client(s) I’ve been experimenting with are launched with the Rackspace plugin (using ‘knife rackspace server create…’) The problem commands seem to fail when talking to the host chef-server, however, before it ever tries to modify the client, so I don’t believe that’s where the problem exists. The virtual-servers that are launched by ‘knife rackspace server create’ are launched properly but then deleting them with knife fails. If I include a recipe in the run_list when I create the server, the recipe is properly added to the run_list. If I try to add it later or remove the one that there server was initialized with, those commands fail. Here is the output of a few relevant commands (with stacktraces): https://gist.github.com/7100ada3fd6690113697

  • Graphics card artifacting

    - by White Phoenix
    This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 @ stock clocks 3x 2GB DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) My graphics card started artifacting while I was playing a game. It artifacted, the display blinked, then I got an NVIDIA driver has crashed and recovered message. Kept going, more artifacts, another crash, but this time my display blanked out and I couldn't do anything. Restarted my computer - artifacting is in the BIOS - got to Windows 7 but it BSOD'd before I could even log in. I restarted the computer again - artifacts cleared themselves out and I managed to get to Win7, but it soon started blinking in and out and artifacting again. Checked the card temps and they're well within range. (50 idle, 70 full load) The ambient temperature here is about 80-85F with high humidity. Tried Safe Mode and it still froze up/BSOD'd. Already tried the following to fix this problem: - Reseat the graphics card and swapped in a different slot. - Removed cover on card and sprayed with compressed air to clean it out. - Swapped around memory and/or went with only using one stick at a time. - Underclocked card I called EVGA Tech Support and they said that the voltage on the 12V rail of my Corsair AX750 PSU was on the high end of the "acceptable" range (12.4V, highest within acceptable range is 12.6V - optimal is obviously 12V). They gave me an RMA number anyway, but I want to get a second opinion from you all before I send this thing off, as shipping from where I live to EVGA is kind of pricey. This PSU is only 6 months old. So that I don't have to play RMA tag, which case would be most likely? I'm strapped for cash at the moment so I want to reduce the amount of RMAs I have to do since shipping is expensive here. Is there any surefire way to test to see if it's really the graphics card or the PSU? I tried unplugging any devices that were connected to the 12V rail (except for my SSD and graphics card) as I do have 3 mechanical hard drives, but the voltage for that rail didn't drop (it remained at 12.4V). I'm fairly sure it isn't the drivers since I'm getting the artifacting at the BIOS too. Right now I'm back in Windows 7 but I don't know for how long until it messes up again. Any ideas?
