  • Why after deleting a 110+ GB collection, my /var/lib/mongodb directory still have same size?

    - by tunnuz
    I am having some troubles with MongoDB and space usage. In particular, I once used to have a large collection of about 600 million records totaling 110+ GB on disk. Recently I decided to drop it because the data was outdated, to do so I dropped the collection through rockmongo's web interface. Accordingly, rockmongo doesn't show me the collection anymore, however my disk usage hasn't changed at all. Is there any clean operation which I am not aware of, which must be run in order to synchronize the database with database files on disk? I have tried to perform a "repair" but the system complains that there's not enough space on disk ... that's because it is all used by MongoDB.

  • Allow Incoming Responses Apache. On Ubuntu 11.10 - Curl

    - by Daniel Adarve
    I'm trying to get a Curl Response from an outside server, however I noticed I cant neither PING the server in question nor connect to it. I tried disabling the iptables firewall but I had no success. My server is running behind a Cisco Linksys WRTN310N Router with the DD-wrt firmware Installed. In which I already disabled the firewall. Here are my network settings: Ifconfig eth0 Link encap:Ethernet HWaddr 00:26:b9:76:73:6b inet addr:192.168.1.120 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::226:b9ff:fe76:736b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:49713 errors:0 dropped:0 overruns:0 frame:0 TX packets:30987 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:52829022 (52.8 MB) TX bytes:5438223 (5.4 MB) Interrupt:16 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:341 errors:0 dropped:0 overruns:0 frame:0 TX packets:341 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:27604 (27.6 KB) TX bytes:27604 (27.6 KB) /etc/resolv.conf nameserver 192.168.1.1 /etc/nsswitch.com passwd: compat group: compat shadow: compat hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis /etc/host.conf order hosts,bind multi on /etc/hosts 127.0.0.1 localhost 127.0.0.1 callcenter # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.120 netmask 255.255.255.0 network 192.168.1.1 broadcast 192.168.1.255 gateway 192.168.1.1 The Url to which im trying to get a connection to is https://www.veripayment.com/integration/index.php When I ping it on terminal heres what I get daniel@callcenter:~$ ping https://www.veripayment.com/integration/index.php ping: unknown host https://www.veripayment.com/integration/index.php daniel@callcenter:~$ ping www.veripayment.com PING www.veripayment.com (69.172.200.5) 56(84) bytes of data. --- www.veripayment.com ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 1007ms PHP Function in codeigniter public function authorizePayment(){ //--------------------------------------------------- // Authorize a payment //--------------------------------------------------- // Get variables from POST array $post_str = "action=payment&business=" .urlencode($this->input->post('business')) ."&vericode=" .urlencode($this->input->post('vericode')) ."&item_name=" .urlencode($this->input->post('item_name')) ."&item_code=" .urlencode($this->input->post('item_code')) ."&quantity=" .urlencode($this->input->post('quantity')) ."&amount=" .urlencode($this->input->post('amount')) ."&cc_type=" .urlencode($this->input->post('cc_type')) ."&cc_number=" .urlencode($this->input->post('cc_number')) ."&cc_expdate=" .urlencode($this->input->post('cc_expdate_year')).urlencode($this->input->post('cc_expdate_month')) ."&cc_security_code=" .urlencode($this->input->post('cc_security_code')) ."&shipment=" .urlencode($this->input->post('shipment')) ."&first_name=" .urlencode($this->input->post('first_name')) ."&last_name=" .urlencode($this->input->post('last_name')) ."&address=" .urlencode($this->input->post('address')) ."&city=" .urlencode($this->input->post('city')) ."&state_or_province=" .urlencode($this->input->post('state_or_province')) ."&zip_or_postal_code=" .urlencode($this->input->post('zip_or_postal_code')) ."&country=" .urlencode($this->input->post('country')) ."&shipping_address=" .urlencode($this->input->post('shipping_address')) ."&shipping_city=" .urlencode($this->input->post('shipping_city')) ."&shipping_state_or_province=" .urlencode($this->input->post('shipping_state_or_province')) ."&shipping_zip_or_postal_code=".urlencode($this->input->post('shipping_zip_or_postal_code')) ."&shipping_country=" .urlencode($this->input->post('shipping_country')) ."&phone=" .urlencode($this->input->post('phone')) ."&email=" .urlencode($this->input->post('email')) ."&ip_address=" .urlencode($this->input->post('ip_address')) ."&website_unique_id=" .urlencode($this->input->post('website_unique_id')); // Send URL string via CURL $backendUrl = "https://www.veripayment.com/integration/index.php"; $this->curl->create($backendUrl); $this->curl->post($post_str); $return = $this->curl->execute(); $result = array(); // Explode array where blanks are found $resparray = explode(' ', $return); if ($resparray) { // save results into an array foreach ($resparray as $resp) { $keyvalue = explode('=', $resp); if(isset($keyvalue[1])){ $result[$keyvalue[0]] = str_replace('"', '', $keyvalue[1]); } } } return $result; } This gets an empty result array.

  • Bridging VirtualBox over OpenVPN TAP adapter on Windows

    - by Sean Edwards
    I'm trying to configure a virtual machine (VirtualBox guest running Backtrack 4) with a bridged adapter over a VPN connection. The VPN is is hosted by the cybersecurity club at my university, and connects to a sandboxed LAN designed for penetration testing against various servers that the club has built. My host (Windows 7 Ultimate) connects to the VPN fine and is assigned an IP through DHCP, but for some reason the VM can't do the same thing, and I'm not sure why. It's like OpenVPN is filtering out packets from the MAC address it doesn't recognize. I want the virtual machine to bridge over the VPN connection, because our IT office has very strict policies about what you can and can't do on the network. I want to be able to run active attacks (ARP spoofing, nmap, Nessus scans) in the sandbox environment without risking the traffic accidentally going over the university network and getting my internet access revoked. Bridging over the VPN connection and running all attacks from inside the VM would solve that problem. Any idea why the host can use this interface, but the VM can't?

  • With the Supermicro Embeded BMC, is it possible to connect to Serial Over Lan via SSH?

    - by Stefan Lasiewski
    I have several dozen Supermicro servers which use the Supermicro Embedded BMC. The documentation on that page suggests that I can access the Serial Over LAN (Serial Console) over SSH: SMASH and CLP support SSH based SOL Power control of the server But when I ssh into my BMC, all I see is a Busybox implementation, with no clear ability to connect to the SOL: # ssh 192.168.100.100 -l ADMIN [email protected]'s password: BusyBox v1.1.3 (2011.02.12-01:48+0000) Built-in shell (ash) Enter 'help' for a list of built-in commands. # show -sh: show: not found # smash -sh: smash: not found Supermicro support is giving me inconsistent answers. Is it possible to connect to the SOL via the SSH interface?

  • Cisco 2811 router ignored input errors

    - by elbekay
    I've got a Cisco 2811 (AdvIPServices 12.4(25e)) that is showing input errors on both its interfaces, all the errors are of the ignored type. The counter for ignore errors is not increasing continuously, which made me think it would be happening in line with traffic bursts, but there really isn't a large amount of traffic running through it at any time. Both the router interfaces are connected to a 4900 (IPBase 12.2(54)) series switch. The only things I can see are: There is a slight mismatch in duplex/speed negotiation settings, one side is set to auto/auto and one full/auto, however they have negotiated fine. There have been a few fallbacks on the interface buffers, and some trims in the public buffers. Any suggestions for things to look at? I will be correcting the duplex neg settings, and might try a buffer tune, but I don't think it will help.

  • KVM machine does not start ssh, network is started, used to work

    - by lleto
    have been searching an pulling my hear out for the last 6 hours. I have a virtual machine that has been running fine for the last six months. I was happy ssh'ing into it and it was running a database and some small apps. Tonight ssh stopped working, so I decided to reboot the machine. I now have the following situation: virsh list --all states machine as running I can ping the machine and get a reply When I ssh to the machine I see "ssh: connect to host [myserver] port 22: Connection refused" nmap does not show port 22 as open I have tried to: - reboot the machine once more (no luck) - mount the filesystem and check /etc/ssh/sshd.conf (has not changed since working situation) - install virsh console, however this does not seem to work When I mount the fs directly using losetup the strange thing is that file dates seem to be frozen in /var/log/ around the time of the crash. If I look in /var/run/ I can see an sshd.pid, but the time is 6 hours ago (and numerous reboots). My virsh xml looks like this: <domain type='kvm' id='21'> <name>myserver</name> <uuid>09678c8d-a99b-1d18-a7af-88d027cc8f93</uuid> <memory>1048576</memory> <currentMemory>1048576</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc-1.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/disk01/myserver'/> <target dev='hda' bus='ide'/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <controller type='ide' index='0'> <alias name='ide0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:e3:13:86'/> <source bridge='br0'/> <target dev='vnet0'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/1'/> <target port='0'/> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/1'> <source path='/dev/pts/1'/> <target type='serial' port='0'/> <alias name='serial0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1'> <listen type='address' address='127.0.0.1'/> </graphics> <video> <model type='cirrus' vram='9216' heads='1'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </memballoon> </devices> <seclabel type='dynamic' model='apparmor' relabel='yes'> <label>libvirt-09678c8d-a99b-1d18-a7af-88d027cc8f93</label> <imagelabel>libvirt-09678c8d-a99b-1d18-a7af-88d027cc8f93</imagelabel> </seclabel> </domain> I'm sort of lost as to where I can look to get the machine up and running again.

  • How to automate wIntegrate import/export?

    - by Paul Ayling
    Our company uses pic database and wIntegrate 4.02 to interface with. How would I go about automating the .wis files for importing and exporting through wIntegrate? Is there some type of macro, software solution or built in routine I can use? At the moment I manually login to pic using wIntegrate and goto run - querybuilder and select the desired .wis script for importing and exporting data and select ok to run. This is not a solution, it needs to be automated. Anyone? Is there some type of point a click freeware recording software? I hate to do a hack job like that but I'm running out of ideas and no one seems to have worked with this software before...

  • Windows 7 client can't connect to CentOS PPTP VPN

    - by Chris
    Have a Macintosh (10.8.2) that connects just fine to a CentOS 6.0 virtual private server (OpenVZ, with PPP added by the host) via PPTP. A Windows 7 Home Premium client (virtualized in Sun's Virtual Box), on the same computer, using the same Ethernet connection, cannot connect to the Linux VPN server. I have iptables disabled (for testing) on the Linux box. I have the Windows firewall turned off. /var/log/messages looks like this, for a Windows connection: Oct 12 18:44:30 production pptpd[1880]: CTRL: Client 66.104.246.168 control connection started Oct 12 18:44:30 production pptpd[1880]: CTRL: Starting call (launching pppd, opening GRE) Oct 12 18:44:30 production pppd[1881]: Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded.

  • Public IP Routing over Private GRE tunnel

    - by Paul
    I have a GRE tunnel configured between two linux boxes. The tunnel works fine. I can ping from each host the other private ip. Head privateip: 10.0.0.1 publicip: 8.8.8.8 Tail privateip: 10.0.0.2 publicip: 7.7.7.7 The public IP on Tail has the network block 9.9.9.0/23 statically routed over the 7.7.7.7 interface. The idea is to make the 9.9.9.0/23 ips work on servers on the 8.8.8.8 network. I configure the tail host to route the /23 block. I mounted a 9.9 IP on the head server. I can ping the 9.9 ip from the tail to the head. I can't ping the 9.9 ip from the public internet. I think I need to add some other routes because of gateway issues, but I can't seem to wrap my mind around it (not a router guy, just beating my way through something that I have never done before and vaguely understand) --danks

    I need some help in define a route I have two connections one from eth0 and other a ppp0 (a 3G card) Not having the ppp0 connection active my route table is: Destination Gateway Genmask Flags Metric Ref Use Iface default DD-WRT 0.0.0.0 UG 100 0 0 eth0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 I can access my webserver from an outside network through ethernet interface Than I have also my ppp0 3G connection active havig the following route table: D estination Gateway Genmask Flags Metric Ref Use Iface default 10.64.64.64 0.0.0.0 UG 0 0 0 ppp0 10.64.64.64 * 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 Now I only can access my webserver in outside networks through the IP of the 3G connection Note that my server is serving at 0.0.0.0 IP (to all interfaces) But I need to get access to webserver to both interfaces ethernet and 3G connection I only can have access to both connection in local network Any help to configure this network to have both interfaces with outside networks access is welcome Can anyone give me an example to configure this network with 2 gateways to give outside networks access One for IP 192.168.1.149 and other for the ppp0 IP 89.214.60.196 Tanks

  • Is there a Windows or Linux equivalent of Soulver calculator application?

    - by Shevek
    I've just been shown a brilliant calculator app called Soulver which is only available on Mac OS X Maths on a Mac as it should be Soulver is a new kind of calculator application which uses a simple yet powerful word-processor style interface instead of the traditional "button" approach to doing math. Main Features No equals button - Soulver instantly calculates as you type. Multiple lines - Soulver lets you do math over multiple lines and edit previous expressions. Flexible to words - Soulver doesn't mind if you include words or labels between numbers. Basic functions - Soulver includes every standard calculator function, like sin(), cos() & tan() Clever English functions - Soulver includes some "English" math functions. For instance you can type "10% off $200" and get $180 Floating palettes - Soulver's answer & stats palettes will give you conversions and statistics on your work as your type Save your work - like a word processor, Soulver allows you to save and reopen your work This is a fantastic concept and I would really like to find it's equivalent for Windows and/or Linux. Any suggestions?

  • Open source alternative for Canonical Landscape?

    - by netvope
    From Canonical: Landscape is an easy-to-use systems management and monitoring service that enables you to manage multiple Ubuntu machines as easily as one through a simple Web-based interface. However, Landscape is not free. The RedHat counterpart Satellite has a free version called Spacewalk, but it doesn't work on Ubuntu. (There is an attempt to port Spacewalk to Debian, but it doesn't look like it's stable yet.) Are there any open source alternative to Landscape? Better yet, are there any Spacewalk-like software that works for both RedHat-based and Debian-based systems?

  • grep pattern interpretted differently in 2 different systems with same grep version

    - by Lance Woodson
    We manufacture a linux appliance for data centers, and all are running fedora installed from the same kickstart process. There are different hardware versions, some with IDE hard drives and some SCSI, so the filesystems may be at /dev/sdaN or /dev/hdaN. We have a web interface into these appliances that show disk usage, which is generated using "df | grep /dev/*da". This generally works for both hardware versions, giving an output like follows: /dev/sda2 5952284 3507816 2137228 63% / /dev/sda5 67670876 9128796 55049152 15% /data /dev/sda1 101086 11976 83891 13% /boot However, for one machine, we get the following result from that command: Binary file /dev/sda matches It seems that its grepping files matching /dev/*da for an unknown pattern for some reason, only on this box that is seemingly identical in grep version, packages, kernel, and hardware. I switched the grep pattern to be "/dev/.da" and everything works as expected on this troublesome box, but I hate not knowing why this is happening. Anyone have any ideas? Or perhaps some other tests to try?

  • Would firewire networking be better than 100Megabit ethernet?

    - by Josh
    My office network has a fully switched 1000Megabit ethernet network. I have an Apple iMac with a Gigabit NIC and FireWire, and a Compaq laptop with a 100Megabit NIC and a 4-pin FireWire interface. Accessing my office's shared drives using my laptop is (obviously) much loswer using my laptop than my iMac. Would I see a noticeible performance boost if I enabled Internet Connection Sharing on my iMac and shared the private ethernet network from my iMac with my laptop over FireWire? FireWire is 480Mbit/sec, right? So would I see roughly 4x speed improvement with such a setup?

  • Huawei b260a gsm modem not forwarding gre for pptp tunnel

    - by Priit
    I have a huawei gsm modem that does not want to let gre through. The goal is to connect into a pptp server thats behind the huawei. In the modems port forwarding settings theres a ready made profile for pptp (1723). After activating that the MS pptp test tools show that connection is being initiated but no gre packets make it to the server. After taking a closer look into the modems iptables rules theres nothing in there about gre. So I tried making gre rules manualy into forward and preroute chains without any success what so ever. As far as I can tell theres no ip_gre module present on the device is that needed for gre forwarding? Thats what I'm afraid of that it doesn't support gre in NAT but how would I turn it into a bridge? The wan interface is ppp0 so bridging it with eth0 would not work right? Is there some iptables rule I could use to make the modem let all the traffic just straight through?

  • How to set WAN side buffers for WRT54GL running Tomato Firmware

    - by Vickash
    I've recently set up a machine running m0n0wall to try and fight buffer bloat and do some traffic shaping. It was more convenient (geographically speaking) to connect the cable modem directly to my old WRT54GL, then pass everything to the m0n0wall machine and have that do the real routing work. It took a bit of work, but it's working pretty well. I have a cable connection. I have m0n0wall set up to utilize only 90% of the specified speed of my subscription, which is fine. But I've noticed that at certain times of the day (possibly when my true bandwidth drops below that 90%), there's more latency if the connection is used heavily, and traffic shaping doesn't seem to work as well. I suspect this is caused by the buffers on the WRT54GL still being unnecessarily large. If the connection is working as expected, they won't get filled, but in times of reduced bandwidth they would. Does anyone know the command I need to execute, on the WRT54GL running Tomato Firmware, to reduce the buffers on the WAN interface to the minimum size possible?

  • Parse HTTP requests through Wireshark?

    - by diogobaeder
    Hi, guys, Is there any way to parse HTTP request data in wireshark? For example, can I expose the request parameters upon an HTTP GET request (being sent by my machine), so that I don't need to read the (sometimes) truncated URL and find them by myself? I was using Tamper Data and Firebug, on my Firefox, to analyse these requests, but they're not as reliable as a stand-alone tool for monitoring my network interface, but wireshark keeps data too raw concerning HTTP flow. If you guys know any other stand-alone tool that does this (must be Linux-compatible), please tell me. Thanks!

  • RAID1 Hard drives with Intel Controller

    - by Dave_H
    I have an older server with 2 35GB hard drives arranged as a RAID-1 drive. I have 3 open bays, I'd like to add 2 more hard drives to the open bays and have all 4 drives configured as a RAID-1 drive that Windows sees as 1 larger drive. Is this possible? If not, the new drives are 2x as big as the old drives, is it possible to replace 1 of the old drives and rebuild then replace the second drive and rebuild and somehow expand the array to use all of the available space? The server is using an Intel hardware raid controller, the software interface is Intel Storage Console v2.12.

  • KVM CLI install for CentOS 6.3 defaults to Minimal Install

    - by i.h4d35
    So I now I've installed KVM (and its associated tools and packages- libvirt, VMM etc.). On the GUI (i.e using the VMM), installation works as its supposed to. However, when I try to create a VM using the command line interface, the OS (I am working with CentOS 6.3) defaults to a Minimal Install instead of giving me options to choose from at the time of installation. I am trying to install using the following command: virt-install \ --connect qemu:///system \ --virt-type kvm --name testVM2 \ --ram 512 --disk path=/var/lib/libvirt/images/testVM2.img,size=8 --vnc \ --cdrom /media/db18de8e-0853-49fb-80de-5c794d58a46f/CentOS-6.3- x86_64-bin-DVD1.iso \ --network network=default Specifying the OS-type or the OS-variant parameters doesn't make a difference. Is there something that I am missing out on or some other parameter that I must specify? Thanks in advance.

  • Using Zebra LP 2844-Z over the network

    - by Jason Kealey
    Hello, I am looking for a network-based label printer. I am looking at this Zebra LP-2844-Z printer. Unfortunately, it does not come with a network interface like the lower-end LP 2824 Plus. The ZebraNet 10/100 Print Server is both expensive for what it does (~$600) and only seems to support wireless networking, not wired. I prefer wired for reliability. Questions: Can I use a cheaper off-the-shelf print server to turn the LP-2844Z to a network printer. Would I get any trouble communicating with the printer via its own programming language or via OPOS? (instead of the Windows driver) Are cheaper print servers reliable? Would I be better to get another printer model that has it built in directly to avoid having issues due to the print server? What other printer would you recommend?

  • Can't resolve localhost on Mac OS X Server

    - by iainbeeston
    I have a server running OS X Server 10.5 and it can't resolve localhost to 127.0.0.1. When I try ping this is what happens: ping localhost ping: cannot resolve localhost: Unknown host SSH and web browsers get similar results (uknown host). If I try using 127.0.0.1 or the ip address assigned on the LAN all of the above work. Here's the contents of my /etc/hosts file: cat /etc/hosts ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost I have no local DNS service running. Does anyone have any idea why this might be happening or how I can fix it?

  • TvTuner as webcamera

    - by BarsMonster
    Hi, I have decent TVTuner which can capture both analog signal & HDMI. I am able to connect my camera and see output of it in realtime in VirtualDub. I want to be able to use it in Skype and other software which use webcams. The problem is that they only use first "videoinput" of my videodevice, but HDMI is 3rd, and there is no interface to switch (in Skype for example)... So could you suggest any "proxy" software which can take video from Tuner, and show as a webcam?
