  • WGet from one site on a server to another site on the same server

    - by JoshReedSchramm
    Hey all, I've recently been asked to administer a couple ubuntu boxes running web servers. I'm a dev by trade so if this question is fairly noob please forgive. We have about a dozen sites running on this box. 2 of our sites need to talk back and forth over a restful api. Unfortunately we are having issues with the sited connection to each other via wget. When we try and run wget manually from the command line from the server pointing to a site also on that server it hangs and eventually times out. If we do the same thing from outside the server to the same site on the server it works. Is there something that could be preventing sites on the same server from communicating with each other? The same thing happens pinging the site from the server.

  • How does one debug Windows network share authentication?

    - by ajs410
    I have machine0 with 32-bit Vista, logged in as a domain user, running a VMWare image of 32-bit Vista, logged in as a local user, with the VM set to bridge the network. From an administrator account (called admin) within the VM, I try to access the hidden C$ share on machine0 (i.e. start - run - "\\machine0\C$\"). I get no prompts for credentials. Worse, machine0 has an admin account (different password), and machine0\admin gets locked out when VM\admin tries to access the network share. I get a message several seconds later, which feels like a cached credential failure leading to the lockout. I have checked several places for cached credentials; net use, Stored Usernames and Passwords, mapped shares. I rebooted (both machine0 and VM) to make sure the session was clear of any cached credentials. I can force net use to use my domain credentials when accessing machine0, and then I can see the share. I can also see shares that do not require credentials. I decided to try another machine on the network (machine1), 64-bit Vista, local user. This machine has no lockout policy, and after several seconds (feels like failed cached credentials again) it prompts me for credentials. After I enter them, it re-prompts me, saying "logon unsuccessful" (tried my domain credentials, and also machine1\admin's). Which is bogus, because I proceed to log on with remote desktop using the machine1\admin credentials. I have tried this on another machine (machine2, 64-bit Vista), running a copy of the same 32-bit VM, and I don't remember having this problem. machine0 has a fingerprint reader...could that try storing passwords and interfere? Are there any places I'm missing where there could be cached credentials? Is there a way to see what credentials are flying around when I try to connect?

  • How to re-run one line of a PowerShell cmdlet if it fails

    - by pansal
    I wrote a PowerShell script which is supposed to send emails automatically, but sometimes the email won't send out due to a network issue. Here is how I'm sending email: $smtp_notification.Send($mail_notification) Here are the error logs: Exception calling "Send" with "1" argument(s): "Failure sending mail." At line:1 char:24 + $smtp_notification.Send <<<< ($mail_notification) + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException Is there anyway to re-run the sending line when I met this failure? Can anyone give me some suggestions please?

    We have followed- http://msdn.microsoft.com/en-us/library/ms404869(v=vs.100).aspx every steps of this extremely poorly worded article. We are not able see Dashboards of SharePoint projects.

  • Recreate/Regenerate vhost config in cpanel for one account

    - by Gabriel
    So my boss as allways was messing with cpanel on our production server (we only have production servers, which is bad enough)... so now all of the accounts is pointing to the default apache page in /usr/local/apache/htdocs instead of /home/useracc/public_html. Is there a way how to tell cpanel/WHM to recreate the vhost configuration of the account from scratch? the account has a database and emails associated with them so before i do anything i don't want to mess anything up with cpanel.

  • 'Singleton' application - or let the user only launch one instance of a program at the time

    - by Disco
    I'm running a few linux desktops; mainly for kids (yeah, trying to teach them the right OS at early stage) (running Ubuntu 10.10, Gnome) The problem is that they found very funny to make their workstations (actually, old 512 Mb pentium 4) by launching thousands of firefox instances. I'm looking for a way to restrict them to launch 'N' instances of a particular application. Haven't figured yet how. Thought of a monitoring daemon but I think that would be too ressources hungry. Any idea of a script/trick to achieve this ? Note: i might have 1-2 level of users (the kids, and the more grown up kids) so i have also to limit per user; something like user1: 3firefox, user2: 2firefox instances.

  • Print same text several time to one page

    - by RiaD
    I have a odt(or pdf, or ps) file. [Really I have odt, but I can easily convert it], it consist of 1 page. No I want to print it to another pdf 4 times to 1 page. There is an option pages per side, so If I copy-paste 4 times my document and set this option to 4 I'll have my expected result. But I want to do it without copy-paste because it's quite annoying to copy-and-paste before each printing. Is it simpler way?

  • User account that is not allowed to edit one file on Ubuntu

    - by spacemonkey
    Hi, I wanted to ask if it is possible to create a user account on Ubuntu so that it had all powers and rights of root account except it would be impossible to edit a certain file. What I intend to do is to edit host file in order to block access of certain websites, and then create a user account which would be the same as root account except it would be not able to edit host file. Maybe there is an easier way to block an access of certain sites forever? Thanks!

  • Could one hypothetically upgrade a computer from Windows 95 to Windows 8

    - by JMK
    Hypothetically, could you start with a computer running Windows 95, upgrade this to Windows 98, then upgrade this to Windows XP, then upgrade this to Vista, then to 7 and finally to 8 (consumer preview)? What state would the OS be in after so many upgrades? Would any of the native Windows 95 apps still be sticking around in Windows 8? Has anybody done anything like this before? I don't need to do this, I am just asking out of curiosity! Thanks

  • Change default root user with a new one on Ubuntu Server

    - by MultiformeIngegno
    I have a VPS, until now I used the default root user for SSH access and everything. For security reasons I'd like to use a different user for root, terminal access and sudo operations. So I created another user, gave him the sudo and every other perm. The problem is that all the system files belongs to root. What happens if I set PermitRootLogin No for root? Those files wouldn't be editable by the new root user!

  • merge two parts of pdf in one

    - by Yurij73
    I have two searchable pdf documents say even.pdf and odd.pdf which contains respectively even and odd pages of a book. I can decompile each pdf to separate files 001.pdf 002.pdf oo3.pdf ....The question is how to merge them? They are both even and odd sequences numbered 1,2,3. If it where other numbering on decompile stage with pdftk for even 1,3,5 and for odd 2,4,6 instead of existing order 1,2,3, 4.. i coulde simple merge them, but i ignore this method of numbering with pdftk. May be i need to do the task in other way?

  • Monitoring instantaneous network throughput at one second intervals?

    - by Shaddi
    For a testing setup I have, I need to monitor the throughput through a "router"* at regular intervals of around 5 seconds or less (sub-second intervals would be very nice, but not required). Ideally, I would be able to generate a file which contained both the number of bytes and packets seen during each interval. I will eventually be generating a time-series of throughput from this data. On a previous setup using an older version of FreeBSD, there was a tool called "bpfmon" which gave me this information. However, I need to do this under a modern version of Linux (namely, Ubuntu 11.04). I have looked at both iptraf and iftop, but these do not appear to provide the resolution I need, nor do they seem to easily allow scraping the data I need. I understand iptables statistics may be able to give me what I'm after, but the examples I've seen of this seem to rely on repeatedly reading and resetting traffic counters, which seems like it could give inaccurate as read/reset is not an atomic operation. I already capture a tcpdump trace of the traffic I'm interested in on the link I want to monitor, so I am open to approaches which simply parse that. I feel like this must be a common problem though, so I am hoping there will be a standard "best practice" tool for accomplishing this. *I say "router" in quotes because I am really talking about a machine with two bridged NICs through which all the traffic I'm interested in passes.

  • Forums that compell one to read? [closed]

    - by Alex
    I want to create a forum for a very specific, somewhat fight-club-like area of information. The participants need to be unique, not people I know. To be precise, it needs to be an entirely random set of participants. To do this I am going on the assumption that whatever a potential viewer sees when he visits this particular domain he will be COMPELLED to go further. He feels an intense urge within him to read more. I need forum software that will evoke this feeling regardless of the content. Minimal and aesthetically fluid and functional. It must have.. zen.. What are my options?

  • Windows 7 losing one of my displays after restart

    - by j_kubik
    I have an Intel DZ68BC motherboard with Intel HD graphics card using two monitors (on DVI and on HDMI » VGA). My friend asked me to test if his NVIDIA graphics card works well on my computer (at his it was doing some trouble), so I inserted it in my computer, installed the NVIDIA driver and it worked quite well. Then I removed it, uninstalled everything NVIDIA-related I could find and switched monitors back to my Intel card. Since then after every system start/restart, the system sees only monitor on HDMI » VGA connector, completely ignoring the DVI monitor. I noticed that installing the Intel video drivers causes the system to recognize the second monitor if I don't immediately reboot. After a reboot, the system recognizes only the HDMI » VGA monitor. I also tried starting in safe-mode and using DriveSweeper to remove the remains of NVIDIA drivers. While it seems that some drivers were removed, the situation didn't change. Now I am out of ideas and I really wouldn't like to reinstall the system (again...). I also tried restoring the system to the state before this whole story, but it also didn't change anything. EDIT: I am still trying to troubleshoot this problem. The only point that I could start was driver re-instalation. I traced down the part that restores right settings to a call: C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\x64\Drv64.exe -driverinf "C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\Graphics\igdlh64.inf" -flags 20 -keypath "Software\Intel\Difx64" This call fixes my displays, and as workaround, I will add it for now to my autorun. I am still looking for better solution anyway... EDIT2: Using DriverView i made a list of currently used drivers both before and after fixing my display using above command. Then i compared logs: No drivers were removed by fixing command. Drivers added by fixing command: MS Remote Access serial network driver (asyncmac.sys) security processor (spsys.sys) Drivers that changed base address (indicates driver-reload?) Canonical Display Driver (cdd.dll) Intel Graphics Kernel Mode Driver (igdkmd64.sys) Monitor Driver (monitor.sys) Added drivers seem rather unrelated to the problem to me, reloaded drivers are just a cnsequence of installing new driver file so there is not much to go here... I really cannot make heads or tails out of it...

  • Can multiple wordpress's feed off one database?

    - by ThomasReggi
    I am a template designer and I want to create one wordpress with all generic posts, but I don't want to have to keep logging in and copy & pasteing the same wordpress posts everytime. Can I point multiple WP installs to one database? A harder way would be export a master db and importing it to each install. Before I go crazy and try to hack something together, does anyone have any advise? -Thanks in advance.

  • jQuery treat hover on two elements as one elements

    I have an image map which I have overlaid with some markers in the form of anchors. I currently have a hover trigger on each image map area and the associated anchor - as shown in screen shot I need to treat these two elements as one, as currently when mouse is moved out of one onto the other it calls .hover() and callback again. I want to call hover callback only when mouse is moved out of either elements.
