  • What is the crappiest network build you've ever seen?

    - by Ivan Petrushev
    This is only about networks you have seen personaly, not heared from others or seen on pictures at the web. Cables hanging from the ceiling lamps? Cables going trough culverts and other tubes? Switches and other equipment in the cleaner's closet? Cleaning lady's rags drying hanging from the cables? Key to the main node door possesed only by the janitor (or other non-tech and completely non-network-related guy)? Switches powered by foreign power adapters (cheaper and providing non-specified voltage or amperage)? All of this was in my old dormitory. Tell us about your bad experience.

  • Tunning scrolling in urxvt

    - by Ivan Petrushev
    Hello, I'm using rxvt-unicode version 9.06 at Ubuntu 9.10. I was used to aterm, where you can use SHIFT + up/down arrow to scroll the printed output with a line up or down. You can also use SHIFT + pgup/pgdown to scroll one screen up or down. In urxvt I can use the pgup/pgdown combination as well, but can't use the up/down arrow combination. It is very useful to be able to scroll by single lines. Do you have any idea how to enable the up/down arrow scrolling? This is my ~/.inputrc: set show-all-if-ambiguous on And this is my ~/.Xdefaults: URxvt*geometry:80x35 URxvt*transparent:true URxvt*shading:40 URxvt*saveLines:12000 URxvt*foreground:White URxvt*background:Blue URxvt*font: -*-terminus-*-*-*-*-14-*-*-*-*-*-*-* URxvt*color4:RoyalBlue URxvt*color12:RoyalBlue URxvt*scrollBar:true URxvt*scrollBar_right:false URxvt*scrollstyle:rxvt

  • Allow access from outside network with dmz and iptables

    - by Ivan
    I'm having a problem with my home network. So my setup is like this: In my Router (using Ubuntu desktop v11.04), I installed squid proxy as my transparent proxy. So I would like to use dyndns to my home network so I could be access my server from the internet, and also I installed CCTV camera and I would like to enable watching it from internet. The problem is I cannot access it from outside the net. I already set DMZ in my modem to my router ip. My first guess is because i'm using iptables to redirect all inside network to use squid. And not allow from outside traffic to my inside network. Here is my iptables script: #!/bin/sh # squid server IP SQUID_SERVER="192.168.5.1" # Interface connected to Internet INTERNET="eth0" # Interface connected to LAN LAN_IN="eth1" # Squid port SQUID_PORT="3128" # Clean old firewall iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X # Load IPTABLES modules for NAT and IP conntrack support modprobe ip_conntrack modprobe ip_conntrack_ftp # For win xp ftp client #modprobe ip_nat_ftp echo 1 > /proc/sys/net/ipv4/ip_forward # Setting default filter policy iptables -P INPUT DROP iptables -P OUTPUT ACCEPT # Unlimited access to loop back iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT # Allow UDP, DNS and Passive FTP iptables -A INPUT -i $INTERNET -m state --state ESTABLISHED,RELATED -j ACCEPT # set this system as a router for Rest of LAN iptables --table nat --append POSTROUTING --out-interface $INTERNET -j MASQUERADE iptables --append FORWARD --in-interface $LAN_IN -j ACCEPT # unlimited access to LAN iptables -A INPUT -i $LAN_IN -j ACCEPT iptables -A OUTPUT -o $LAN_IN -j ACCEPT # DNAT port 80 request comming from LAN systems to squid 3128 ($SQUID_PORT) aka transparent proxy iptables -t nat -A PREROUTING -i $LAN_IN -p tcp --dport 80 -j DNAT --to $SQUID_SERVER:$SQUID_PORT # if it is same system iptables -t nat -A PREROUTING -i $INTERNET -p tcp --dport 80 -j REDIRECT --to-port $SQUID_PORT # DROP everything and Log it iptables -A INPUT -j LOG iptables -A INPUT -j DROP If you know where did I miss, please advice me.

  • Intel mobile CPU power consumption at idle levels?

    - by Ivan Petrushev
    I was wondering if someone has observations (or specifications) of different mobile processors power consumption levels when idle? Let's define 'idle' with 'browsing web sites trough wifi, no flash, no multitasking'. There are different series processors, recognizable by their first letter. The letter tells about the maximum TDP. For example: T - 30-39W P - max 25W L - 12-19W U - <12W However this is about maximum consumptions during load. Is there any difference in power levels when the CPU is idling?

  • How can you get internet on a train?

    - by Ivan Petrushev
    Hello, There are some rail road companies offering an internet connection to their customers. How can they do it? What kind of internet connection can they have on board a moving vehicle? Satellite connection? I think the train movement will displace a mounted dish and it also will have to be constantly moved around to find the satellite as the train makes turns. Speed isn't greater either. GSM connection - EDGE, UMTS, CSD? 3G coverage often is not an option in rural areas where train goes. These kinds of technologies doesn't offer good speed. WiMax? Wikipedia article on it says it could provide 40Mbps for long distances. Is that what they use mostly? Some kind of power line internet carrier?

  • How to copy a dynamic TrueCrypt volume quickly?

    - by Ivan
    I have created a dynamic TrueCrypt volume file, set it size to 40 GiB and put about 20 GiB of files on it. When I open the volume file properties it says "Size: 40.0 GB, Size on disk: 23.0 GB". When I try to move the volume file to another physical partition it takes a lot of time as it tries to copy all the 40 GB instead of just 20 GB that the volume file actually takes. Also, when it is less than 40 GB free on the target drive it says insufficient space even though it is more than enough space considering how much does the image file actually take. How do I overcome this? Creating a new volume file on the target drive works but needless to say I'd like a better solution.

  • How to configure all the special IMAP folders in Outlook?

    - by Ivan
    Using different versions of Outlook with an IMAP mail account I have found how to configure Outlook 2007 to use particular folder for sent mail (but not any more). I have also found how to specify the deleted mail folder in Outlook 2010 (but not in 2007). But I'd like to choose specific sent, junk, deleted and draft mail folders. Is there a way? Perhaps a hack/patch of a sort if there is no standard way?

  • Mac OS X Snow Leopard: permissions changed on /var results in dns lookup issues

    - by Ivan
    I was attempting to solve an issue ("/var/log/msmtp.log: permissions denied" error when attempting to send mail using msmtp) when I did this: > chmod -R 770 /var After that, my machine would not resolve domain names via cURL. (ping also fails) But, oddly, I can enter domain names into Safari and visit any web pages w/o a problem... I'm actually not sure if the chmod command is the cause of the problem, but I suspect it is. Also, if I ls -l on /var (or /private/var) it doesn't seem that any of the subdirectories or files there actually changed permission, but there are many, so I can't say that conclusively... Incidentally, I fixed the original error (msmtp.log permission denied) by setting TMPDIR=/tmp in my local environment (bash). Now the error goes away, but I get this error: msmtp: cannot locate host domainname.org: nodename nor servname provided, or not known Any ideas about how to go about getting DNS working again?

  • Starting nginx with systemctl fails, but running the command manually doesn't

  • What command to use to unpack a .tar.gz file in Windows?

    - by Ivan
    I use to receive tar.gz files fromm colleagues but unpacking them with 7zip is not convenient as it unpacks a tar file from gz first while I usually seek to get the tar file contents (so I have to unpack the tar file explicitly next). I've tried adding tar -zxvf %P%N command to Total Commander button bar but it turned that tar -zxvf doesn't work but returns the following error (tried it in bare command prompt): tar: Cannot fork: Function not implemented tar: Error is not recoverable: exiting now I have got both GnuWin32 and cygwin installed, but I seek a solution that will work in Windows command line promt (and so will be callable from Totat Commander), not in cygwin command line promt.

  • php server settings for restrict post queries

    - by Korjavin Ivan
    I have php script on hosting, which receive big data with ajax/post. Just now, after some works on hosting, I see that script is broken. I checked with curl: file temp1: user_avatar=&user_baner=&user_sig=.... 237 chars total, and curl -H "X-Requested-With: XMLHttpRequest" -X POST --data @temp1 'http://host/mypage.php' works perfect. But with file temp2: name=%D0%9C%D0%B5%D0%B1%%B5%D0%BB%D1%8C%D0%A4%%B0%D0%B1%D1%80%D0%B8%D0%BA%D1%8A&user_payed=0000-00-00&...positions%5B5231%5D=on total chars: 65563 curl -H "X-Requested-With: XMLHttpRequest" -X POST --data @temp2 'http://host/mypage.php' curl return nothing. Looks like a problem with apache/php/php.ini or something like that. I check .htaccess php_value post_max_size 20M Which other parameters I should check? Is it possible that %BO encode kill php/apache? Or total number of parameters (about 2800) ?

  • middle click works only once

    - by Ivan Peevski
    Just recently I'm having problems with middle click. After a reboot, it works the first time I use it, but then it doesn't work after that. As far as I've investigated, that's the same on Linux and Windows. The mouse is Reaper ZMS-1000. To me it sounds like a hardware issue, but it's strange that it works after a reboot every time just for one time. Any suggestions?

  • After logging out of SSH, screen sessions disappear on Arch Linux

    - by Ivan
    On Arch Linux (I'm on a single dedicated server, where my domain name points to only one IP), when I SSH into a user (say, for example, user mc), and then do screen -S test (or -dmS, the resulting issue is the same), run a command, and then detach from it, then exit out of my SSH session, and log back in, the screen session disappears. screen -ls returns No Sockets found in /run/screens/S-mc. The only way I can reattach to my sessions is if I never logged out of my SSH. How do I fix this? I do have read/write access in /run/screens/S-mc I detach from screen sessions with Ctrl-A,D disown -a && exit gives me the same problem shopt huponexit returns "huponexit off" There is no ~/.logout, and ~/.bash_logout is empty, with 3 lines of comments, telling me it's the ~/.bash_logout file ls -l /usr/bin | grep screen returns lrwxrwxrwx 1 root root 12 Oct 31 2012 screen -> screen-4.0.3 -rwsr-xr-x 1 root root 363672 Oct 31 2012 screen-4.0.3

  • Why would you use EAP-TTLS instead of PEAP?

    - by Ivan Macek
    As I understood EAP-TTLS and PEAP share same level of security when implemented in wireless networks. Both only provide server side authentication via certificate. The drawback of EAP-TTLS can be non native support in Microsoft Windows so every user has to install additional software. The benefit of EAP-TTLS can be support for less secure authentication mechanisms (PAP, CHAP, MS-CHAP) but why would you need them in modern and properly secure wireless system? What are you opinions? Why should I implement EAP-TTLS instead of PEAP? Let's say that I have most Windows users, medium Linux users and least iOS, OSX users.

  • Netbeans multi row tab bar?

    Is there a way to put Netbeans open files tab bar into several rows? I have to scroll left and right when I open more than 3-4 files. For Firefox there is that extension "Tab Mix Plus" that provides that option. Is there a plugin or setting for this in Netbeans?

  • How to find who deleted a line from a file in a SVN repository?

    - by Ivan Petrushev
    Hello, I work on a very large project (10000+ versions) and sometimes it happened that I need to know who of the other users deleted some line in a file. Is there a way to do that that? I can do svn blame with revision number to check if a line exists in that revision, then see in which revision the line is gone and see who commited that revision, but that procedure is lame with that large project. Is there a smarter way to do that?

    - by Ivan Perekluyev
    Hi, i need to build mapnik on freebsd 6.3, but port marked as 'broken', so i forced to build it from source. With boost 1.41 (which is in ports) mapnik doesn't build. somewhere in internet, i found that mapnik successfully builded with boost 1.42. So, i download patch from wiki.freebsd.org/BoostPortingProject andd apply it: wget http://alexanderchuranov.com/boost-port/boost-from-1.41-to-1.42-2010-02-16-17-11.diff cd /usr/ports patch -p0 -i ~/boost-from-1.41-to-1.42-2010-02-16-17-11.diff after that, i trying to install boost-all metaport, but its failed. cd devel/boost-all make install 2>&1 | tee build.log tail -n 100 build.log > short_build.log Build.log (attention, 5m !): dl.dropbox.com/u/7365614/build.log Short build log: http://paste.pocoo.org/show/224474/ Thanks!

  • How to use a custom Windows 7 system drive letter?

    - by Ivan
    The subject PC has many hard drive partitions dedicated for different purposes, C: being a Windows XP system drive and F: (which is actually the next primary partition placed right after C: physically) being intended to host a newly installed Windows 7 instance (meant for "dual boot" configuration). Needless to say the intention was all the partitions to have exactly the same letters under both OSes, needless to say Windows 7 has detected all of them in a completely different order which would not be a problem (as the non-system drives letters can be changed easily after installation) if it wouldn't have named it's system drive C: (meant to be F:), which I have no Idea how to change. Is there a way to set the letter you want? I don't mind reinstalling Windows 7 from scratch if it is to be set at installation time or even configured in some text files on the installation DVD. I have tried this way, but it renders the Windows 7 system desktop unbootable (gets stuck on "Preparing your desktop..." after "Welcome").
