• Debian Bluetooth headphones not working

  - by cYrus

  Hardware Headphones Bluetooth dongle Maybe not exactly these models. Setup I tried to follow some guides, here's what I've done so far: Install software: sudo apt-get install bluez-utils bluez-alsa Reboot (just to be sure): $ dmesg | grep -i bluetooth [ 20.268212] Bluetooth: Core ver 2.16 [ 20.268230] Bluetooth: HCI device and connection manager initialized [ 20.268233] Bluetooth: HCI socket layer initialized [ 20.268235] Bluetooth: L2CAP socket layer initialized [ 20.268239] Bluetooth: SCO socket layer initialized [ 20.284685] Bluetooth: RFCOMM TTY layer initialized [ 20.284692] Bluetooth: RFCOMM socket layer initialized [ 20.284693] Bluetooth: RFCOMM ver 1.11 [ 20.335375] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 20.335378] Bluetooth: BNEP filters: protocol multicast The deamon is running: $ /etc/init.d/bluetooth status [ ok ] bluetooth is running.

• On Windows machines, what is the typical toolchain for remote maintenance?

  - by Hanno Fietz

  I need to deploy PHP and Python code and the appropriate environment (web server, db server) to remote Windows systems, and I don't know what toolchain would be the equivalent to ssh, scp, bash and the like. So, basically, what I need to be able to do is the following: access remote Windows with the appropriate privileges in a secure manner, like I routinely do with ssh (I don't even know whether that would be a text or graphic interface on Windows). remotely install software: Apache or IIS, MySQL or Postgres, Python or PHP copy files from remote (the application we're deploying) remotely configure the machine to run regular tasks (e. g. checking for updates to the application) automate tasks like downloading files from a designated place The main question is probably how I get onto the machine securely in the first place, and then the rest is general Windows admin knowledge, which probably is too broad a scope to fit into one question. I have years of experience with maintaining Linux boxes and I have used tools of varying sophistication on those, ranging from plain scping of PHP files to deployment of Java application containers and even full VMs with Vagrant. On Windows, I'm a complete noob, and I don't even know where to start. I have installed Apache, MySQL , PHP on a desktop machine maybe twice in my life, that's about it. Bonus points for things that work from a Linux machine at my end, but I could run a VM and do everything from there.

• "Can't find root filesystem / error mounting /dev/root" when booting to new kernel

  - by salparadise

  I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers. When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common_kernel_problems#Can.27t_find_root_filesystem_.2F_error_mounting_.2Fdev.2Froot From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel. Doing a diff from the old initrd to the new one gives me the following: root-> diff /tmp/kafter /tmp/kbefore 6a7,8 > lib/dm-message.ko > lib/dm-region_hash.ko 8a11 > lib/dm-raid45.ko 13d15 < lib/dm-region-hash.ko 16a19 > lib/dm-mem-cache.ko Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid. I have the same SATA and IDE options configured for both kernels so not sure what else to look for, any help is appreciated.

• How do you initialize networking on a new Xen guest VM?

  - by Marten Veldthuis

  We have a Citrix XenServer setup, and while I personally lean more towards Dev than Ops, I've got an issue that's been bugging me. When you provision a new (Linux/Ubuntu) guest, how do you get it to have the correct IP-address? I'd want my application servers to exist in the range of 10.20.0.0/24, preferably being .1, .2, etc, so I can keep my sanity. I guess that the actual IP-address is something set in Linux itself, and Xen can't touch that, but then what's the best practice for getting it done? If you set up DHCP, don't you just move the problem to getting the adapters the "correct" MAC-addresses? Do you just have to hardcode a large table of MAC-addresses to IP-addresses, and then provision new guests always with the correct MAC-address on the virtual ethernet adapter? What we currently do is have an image of a "app server" that we boot up a new instance of, and then finalize it (with a script) that (among other things) modifies the /etc/networking/interface file to give it the correct IP. But that feels dirty to me, and I feel like surely there must a better way. Please enlighten me?

• Debian, 2 NICs load-balancing or agregating with one same gateway

  - by pouney

  Hi, I have one server, with double NICs connected to one switch with the same gateway. Behind the switch we have internet. |Debian| - eth0 - switch - internet - eth1 - same I don't understand how to load-balancing between eth0 and eth1. The inbound/outbound traffic always use eth1. This is the config: # The primary network interface allow-hotplug eth0 auto eth0 iface eth0 inet static address 192.168.248.82 netmask 255.255.255.240 network 192.168.248.80 broadcast 192.168.248.95 gateway 192.168.248.81 allow-hotplug eth1 auto eth1 iface eth1 inet static address 192.168.248.83 netmask 255.255.255.240 network 192.168.248.80 broadcast 192.168.248.95 gateway 192.168.248.81 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.248.80 0.0.0.0 255.255.255.240 U 0 0 0 eth1 192.168.248.80 0.0.0.0 255.255.255.240 U 0 0 0 eth0 0.0.0.0 192.168.248.81 0.0.0.0 UG 0 0 0 eth1 0.0.0.0 192.168.248.81 0.0.0.0 UG 0 0 0 eth0 Ips aren't real, it's just for the example. Anybody have an idea on correct routing to use eth0 on 192.168.248.82 and eth1 on 192.168.248.83 ? I have many example for multiple gateway but here it's the same. Thanks all. Regards

• Why does my Intel Tolapai network chip not transmit packets?

  - by Hanno Fietz

  I'm trying to deploy an embedded system (NISE 110 by Nexcom) based on the Intel EP80579 (Tolapai) chip. Tolapai apparently integrates controllers for Ethernet etc. on a single chip (Intel homepage). The machine can't get a network connection. Diagnosis as far as I could manage: Drivers drivers from Intel compiled and installed without problems (version 1.0.3-144). Kernel version and Linux distribution (CentOS 5.2, 2.6.18) match the driver's installation instructions. drivers are loaded and show up in lsmod (module names are gcu and iegbe) interfaces eth0 and eth1 show up in ifconfig ifconfig I can bring up the interfaces with fixed IP pinging the interface locally works ifconfig shows flag UP but not RUNNING Link ethtool shows "Link detected: no", "Speed: unknown (65536)" and "Duplex: unknown (255)" Link LED is on on the other side of the cable, ethtool shows "Link detected: yes" and reports a speed of 1000 Mbps, which has allegedly been auto-neogotiated with the problematic device. Network traffic analysis the device does not reply on ARP, ICMP echo or anything else (iptables is down) when trying to send ICMP or DHCP requests, they never reach the other end activity LED is off on the device, on at the other end. I tried the following without any effect: Different cables (2 straight, one crossed), I get the link LED lit up on each. Three different devices on the other end (one PC, one netbook, one router) Fixed ARP table entries on both sides Connecting both network ports of the machine with each other, won't ping through the cable, but will ping locally. Tried straight and crossed cables for that.

• Fedora 15: em1 recently dissapeared and hostapd no longer serves internet to wirelessly connected devices

  - by Daniel K

  I have a laptop running hostapd, phpd, and mysql. This laptop uses an Ethernet connection to connect to the internet and acts as a wireless access point for my workplace's wifi devices. After installing some software and reconnecting my Ethernet elsewhere, my "em1" device is no longer present and wirelessly connected devices can no longer reach the internet. The software I recently installed is: pptp, pptpd, and updated some fedora libraries. I have also recently moved my desk and laptop to another location and thus had to reconnect the Ethernet elsewhere. Wifi devices no longer have access to the internet. Wirelessly connected devices are able to successfully log into the laptop, showing full strength, correct SSID, and uses the proper password. However, when I tried to connect to a site like google, the request times out. The device "em1" also no longer appears on my machine. Running: # ifup em1 will give me the following output: ERROR : [/etc/sysconfig/network-scripts/ifup-eth] Device em1 does not seem to be present, delaying initialization. And running: # dhclient em1 has the following output: Cannot find device "em1" When I run # dmesg|grep renamed, I get the following: renamed network interface eth0 to p4p1. I've tried to connect to the internet through p4p1 directly from the laptop and was successful. However, my wireless devices connected to my laptop are not able to connect to the internet. I have uninstalled pptp and pptpd using # yum erase ... but the problem still persists. To install pptp I used: # yum install pptp To install pptpd I did the following: # rpm -Uvh http://poptop.sourceforge.net/yum/stable/fc15/pptp-release-current.noarch.rpm # yum install pptpd To update my fedora libraries I used: # yum check-update # yum update EDIT: Running # route produces the following results: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.11.200.1 0.0.0.0 UG 0 0 0 p4p1 10.11.200.0 * 255.255.252.0 U 0 0 0 p4p1 172.16.100.0 * 255.255.255.0 U 0 0 0 wlan0

• Can't display RSSI values in Wireshark

  - by Giovanni Soldi

  I am trying to analyze the up-link Wireless traffic generated by my Sony Ericsson phone and captured by my D-Link router, on which I installed the DD-WRT firmware. To do this, first I log in the router and enable the prism0 interface by typing the command: wl -i eth1 monitor 1 and then I start to capture the packets by typing: tcpdump -i prism0 ether src xx:xx:xx:xx:xx:xx -s0 -w /tmp/smbshare/sony_ericsson_test.pcap where xx:xx:xx:xx:xx:xx is the MAC address of my Sony Ericsson phone. After a while I transfer the sony_ericsson_test.pcap file to my computer and open it with Wireshark program. In order to display the RSSI values I follow this procedure: Edit - Preferences... - Columns - Press "Add" button - As "Field type" I choose "IEEE 802.11 RSSI" and finally I choose name "Power" and click on "Apply" button. The problem is that the column "Power" is empty with no RSSI values. Does Anyone has a clue on why are RSSI values not displayed? Maybe I am missing a passage. Looking forward to hearing from anyone of you! Thanks in advance for your help!

• HP Power Manager SMTP setup doesn't have space for username & password

  - by Martha

  Is there some way to configure HP Power Manager to not assume that there's an email server running locally? We recently acquired an HP T1500 G3 UPS, which we're trying to control using HP Power Manager 4.2. The main reason we wanted to get this particular UPS is because it says it's capable of sending notifications (of the "Yo, the power's out, you may want to look into it" type) via email, as opposed to SNMP. Turns out, that's not entirely true. The server is running Windows Server 2003. It is not running an email server of any sort - we do that via two different providers. Outlook email is provided by Verizon, and our SMTP email service is provided by a small local company. When we use CDO to send auto-generated notification emails, we have to provide the SMTP server name, port, username, and password. The HP Power Manager interface only allows us to enter the server name and the username. Thus, not surprisingly, the emails never go anywhere. Help?

• How to place a virtual machine in DMZ?

  - by Giordano

  I have an Ubuntu 12.04 server running few virtual machines with KVM. I would like to expose some of these virtual machines on the internet, to make it possible for customers to test the products we're developing and make available other products for demo purposes. One of the server NICs is configured with a public IP. However before exposing anything on the web I would like to be sure that if one of the virtual machines get compromised, the attacker doesn't reach the rest of the hosts. What I would like to do is to put these virtual machines into a DMZ. These are the steps I'm planning to do: Create a tap interface in the virtualization host (let's say tap1) Create a bridge using tap1 and give it an IP in a subnet separate from the other hosts. Let's say 10.0.0.1 Attach the DMZ virtual machines to the bridge and configure their IP statically (10.0.0.2, 10.0.0.3, etc...) Using UFW, forbid any traffic from 10.0.0.0/24 to any of the internal hosts, allow the traffic from the internal hosts towards 10.0.0.0/24 and expose the virtual machines on the web using port forwarding. Do you think this setup is safe? Can you suggest any improvement or a better/safer approach? Thanks in advance!

• VLAN Tagging Traffic on Cisco Switch

  - by David W

  I have a situation where I'm setting up multiple VLANS on a pfSense firewall on the same physical interface for a client. So in pfSense, I now have VLAN 100 (employees) and VLAN 200 (students - student computer lab). Downstream from pfSense, I have a Cisco SG200 switch, and coming off of the SG200 is the student lab (running on a Catalyst 2950. Yes, that's old, but it works, and this is a poor nonprofit we're talking about). What I'd like to do is tag everything on the network as VLAN 100, except for the student computer lab. Earlier today when I was on-site with the client, I went into to the old Catalyst 2950, and assigned all of its ports to access VLAN 200 (switchport mode access vlan 200) without setting up a trunk on the Catalyst or on the SG200. Looking back on it, I now understand why internet in the lab broke. I reverted the lab back to the default VLAN1 (we're still running on a different firewall - we haven't deployed pfSense -, and the traffic is still separated physically). So my question is, what do I need to do in order to properly deploy this scenario? I believe the correct answer is: Ensure VLANs 100 and 200 are setup in pfSense, and that DHCP is operating correctly (on separate subnets) Setup a trunkport VLAN that allows both 100 & 200 traffic, and plug that port directly into pfSense. Setup a VLAN 200 trunkport on the SG200 (It's not running iOS, but if it were, the command would be switchport trunk native vlan 200), which will then plug into the Catalyst 2950. Setup a VLAN 200 trunkport on the Catalyst 2950 (that is plugged into the SG200 VLAN200 port with the same command - switchport trunk native vlan 200) Setup the rest of the ports on the old Catalyst 2950 in the lab to be access ports on VLAN200. Is there anything that I'm missing, or do I need to tweak any of these steps, in order to properly segment the network traffic?

• Comprehensive solution for managing patches, event viewing, change management, inventory, etc

  - by Holocryptic

  I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

• Internet explorer rejects cookies in kerberos protected intranet sites

  - by remix_tj

  I'm trying to build an intranet site using joomla. The webserver is using HTTP Kerberos authentication with mod_kerb_auth. Everything works fine, the users get authenticated and so on. But if i try to login to the administrator panel i can't because IE does not accept the needed cookies. No such problem with firefox. The intranet site is called "intranet_new" and is hosted by webintranet04, under the directory /var/www/vhosts/joomla/intranet_new/. I have my virtualhost for intranet_new containing this: <Location /> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms PROV.TV.LOCAL Krb5KeyTab /etc/apache2/HTTP.keytab require valid-user </Location> The same is for webintranet04 virtualhost, which is the default pointing to /var/www and contains: <Location /vhosts/joomla/> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms PROV.TV.LOCAL Krb5KeyTab /etc/apache2/HTTP.keytab require valid-user </Location> the very strange problem i have is that if i open http:// webintranet04/vhosts/joomla/intranet_new/administrator IE allows me to login, accepting cookie. If i open http:// intranet_new/administrator, instead, i loop on the login page. Last, intranet_new is a CNAME record of webintranet04. This is only an IE problem. I need: - the admin interface to work with IE - the "kerberized" zone to accept cookie, because i am deploying other programs requiring cookies.

• Is Cherokee (probably) the best static content server for beginner sysadmins?

  - by Bad Learner

  I have read the pros and cons of most of the popular web servers and have come to a conclusion that Apache would (probably) be the best web server for serving dynamic content - - no wonder YouTube, Flickr and Facbook, among many others, use it. I do not know if that C10K problem applies to Apache even when serving dynamic content only, but I think any web server used to serve dynamic content needs some good tweaking for optimized performance, and the fact that nothing beats Apache when it comes to documentation, resources and support on the web, I think should will go with Apache for dynamic content. That apart, the confusion begins when it comes to choosing web servers for static content (including streaming videos). I see that Nginx, Cherokee and Lighttpd are among the best (I am not considering non-open source or non-linux stuff here). So, which too choose? I know one cannot go wrong with any of the three (Nginx, Cherokee, Lighttpd). Lighttpd's development has evidently gotten slower than it was a good time ago. The documentation is pretty good for all the three, and hopefully, so are the resources (knowledge of these among the users of Stackoverflow/Serverfault sites, the web etc). Precisely, and noting point [2] and [3], if I am not wrong, I should either go with Nginx or Cherokee. I would love to see someone clarify these... is Cherokee just as fast (mb/s), performant (connections/s), and reliable (think downtime/restarting server) as Nginx for serving static content and load balancing, for small, medium to large (and really large) websites and applications? (Think, the size of YouTube, Apache or Facebook.) if the answer for the Q above is a big "hell, yes!" then, I should probably prefer Cherokee, right? Because, since I am a beginner, it would a lot easier to setup Cherokee as it has a graphical admin user interface + really good documentation. Yes? I could be wrong, I could be right. I put down what I know so that you can offer most relevant advise. Pardon if anything I've said is offensive.

• Windows VirtualBox failed to attach USB device to Linux Guest

  - by joltmode

  I have Windows 7 64bit Host system, and I am using VirtualBox 4.1.18 (r78361). I have an Arch Linux Guest OS. I have installed VirtualBox Extension Pack (to enable USB2 support) and added my USB device filter to VM. I have also installed the Guest Additions provided by Arch: virtualbox-archlinux-additions (but I have no idea whether it's actually needed for my environment). I can see my USB device from VirtualBox Devices menu. Whenever I am trying to access it, I end up with: Failed to attach the USB device Kingston DT 100 G2 [0100] to the virtual machine Archlinux. USB device 'Kingston DT 100 G2' with UUID {a836ec33-0f41-4ca7-a31d-09cceaf5d173} is busy with a previous request. Please try again later. Details ?

• IPTABLE & IP-routed netwok solution for HOST net and VM's subnet

  I've got ProxmoxVE2.1 ruled KVM node on Debian and bunch of VM's guests machine. That is how my networking looks like: # network interface settings auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address 175.219.59.209 gateway 175.219.59.193 netmask 255.255.255.224 post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp And I've got two working subnet solution auto vmbr0 iface vmbr0 inet static address 10.10.0.1 netmask 255.255.0.0 bridge_ports none bridge_stp off bridge_fd 0 post-up ip route add 10.10.0.1/24 dev vmbr0 This way I can reach internet, to resolve outside hosts, update and download everything I need but can't reach one guest VM out of any other VM's inside my network. The second solution allows me to communicate between VM's: auto vmbr1 iface vmbr1 inet static address 10.10.0.1 netmask 255.255.255.0 bridge_ports none bridge_stp off bridge_fd 0 post-up echo 1 > /proc/sys/net/ipv4/ip_forward post-up iptables -t nat -A POSTROUTING -s '10.10.0.0/24' -o vmbr1 -j MASQUERADE post-down iptables -t nat -D POSTROUTING -s '10.10.0.0/24' -o vmbr1 -j MASQUERADE I can even NAT internal addresses: -t nat -I PREROUTING -p tcp --dport 789 -j DNAT --to-destination 10.10.0.220:345 My inexperienced mind is ready to double VM's net adapters: one for the first solution and another - for second (with slightly different adresses) but I'm pretty sure that it's a dumb way to resolve the problem and everything can be resolved via iptables/ip route rules that I can't create. I've tried a dozen of "wizard manuals" and "howto's" to mix both solution but without success. Looking for an advice (and good reading links for networking begginers).

• Setting up port forwarding for web server

  - by Javier Badia

  This could belong on Super User, but I thought this place was more appropiate. I want to run Apache in my computer and want to make it available to the outside world to test a couple things. Apparently, I have to go into my router's (a TP-LINK TD 8910G) settings and forward port 80 to my PC's IP. So far so good. Thing is, since the router uses a web based interface and it's kind of stupid, it told me that since I was using port 80 for this, I should access its settings through port 8080. Maybe it can't detect requests coming from the LAN, I don't know. Point is, now neither port can't access the configuration, and I can't access Internet. Specifically, trying to access anything (including 192.168.1.1, the router's settings) through port 80 turns up a blank page (maybe if I had the server running in my computer I'd get something, but I don't want to risk trying, I had to reset the router and restore the settings), and port 8080 gives a "Can't establish connection" error in Firefox (and similar ones in other browsers). Is there a way to configure the router to not redirect requests coming from inside the network? I'm a beginner with this stuff, so please try to explain in a simple way. If this is more appropiate in Super User, I'm sorry.

• Thecus N5200, disk has dropped out of RAID5

  - by Anders Ekdahl

  We have a Thecus 5200 NAS here at work with five WD Caviar Black 2TB disks in a RADI5 array. Yesterday, disk 4 dropped out of the array, and in the NAS web interface there's a warning about the RAID array being "degraded". When I go into Storage - Disks, disk 1 and 4 has a warning next to them. When I click on the warnings, this information about the disks are displayed: Tray Number 4 Model WD2001FASS-00W2B Power On Hours 2403 Hours Temperature Celsius 34 Reallocated Sector Count 66 Current Pending Sector 1447 Raw Read Error Rate 61 Seek Error Rate 0 Hardware ECC Recovered N/A Tray Number 1 Model WD2001FASS-00W2B Power On Hours 2403 Hours Temperature Celsius 32 Reallocated Sector Count 0 Current Pending Sector 1465 Raw Read Error Rate 0 Seek Error Rate 0 Hardware ECC Recovered N/A I'm not really an expert on either disks or RAID arrays. Does this indicate that the fourth disk is damaged, and needs to be replaced? And what about disk number one? It has a warning, but it's still in the array. Is it safe to add the fourth disk back into the array as a spare? I can't find any way to add it back as a it were before.

• Best all in one linux based proxy,firewall, dhcp and wins server.

  - by BeStRaFe

  I help to run a lan in Sydney. We have a need for a proxy/gateway solution to allow those pesky games that require internet to work. I have been doing this with an ISA server and it has worked quite well. However now i wish to port this over to run on the same hardware as our cacti / nagios box under a vmware VM. ISA server is horridly nad due to the massive ram and i/o requirement for something is basically port blocking and handing out IP's. The needs are as follows. 1. DHCP 2. WINS (otherwise network devices fight over who is the WINS master) 3. Filtering based in PORT for outbound traffic. 4. Ability to whitelist IP/MAC's for internet access. 5. Web Interface. I had been thinking to use PFSENSE however there is no option for a WINS server and i cbf working my way around bsd.

• How to merge arbitrary snapshot into base vdi in Virtualbox

  - by jmathew

  I botched a transfer of a VM from one harddisk to the other. Now I'm left with the base vdi and a whole bunch of snapshots. My steps Copied old VM directory over to new HDD Deleted old VM and added new VM using using Machine-add and providing the old XML file Couldn't add base vdi file due to conflict so changed the UUID of base vdi with VBOXMANGE.EXE internalcommands sethduuid <path/to/vdi> Attempt to rollback to a snapshot, but it seems the VM is looking for the snapshots on the old HDD (which is formatted and gone) This is the error (networked is the name): Failed to restore the snapshot networked of the virtual machine lfs. Could not open the medium 'H:\vm\ft.vdi'. VD: error VERR_PATH_NOT_FOUND opening image file 'H:\vm\ft.vdi' (VERR_PATH_NOT_FOUND). Result Code: E_FAIL (0x80004005) Component: Medium Interface: IMedium {53f9cc0c-e0fd-40a5-a404-a7a5272082cd} The old HDD was drive H: the new one is drive N: How can I modify the snapshots/VM to look in N:\vm\ft.vdi for the base vdi? I've already set the default settings in VirtualBox in general (default vm/vm snapshot location). Or if not that how can I merge the old snap shot with the base vdi given that the only things that have changed is the base vdi's UUID?

• Route return traffic to correct gateway depending on service

  - by Marnix van Valen

  On my office network I have two internet connections and one CentOS server running a website (HTTPS on port 443). The website should be publicly accessible through the public IP of the first internet connection (ISP-1). The other internet connection, ISP-2, id the default gateway on the network. Both internet connections have routers (the household-kind) with NAT, SPI firewalls etc. The router on ISP-2 is a Netgear WNDR3700 (aka N600) with original firmware. The problem is that the website is unreachable. Looks like incoming traffic on ISP-1 will reach the server but the returning traffic is routed through ISP-2, effectively making the site unreachable. As far as I can tell I can't do port based routing on the WNDR3700. What are my options to make this work? I've been looking at implementing an iptables / routing based solution on the server itself but haven't been able to make that work. Update: Note that the server has one network interface connecting it to both routers.

• Can Octopussy use messages other than syslog style?

  - by Lee Lowder

  I am currently exploring different options for a centralized log server. We use both Linux (Ubuntu 10.04 / 12.04, LTS for both) and Windows, though for this specific issue only Linux is relevant. I like the interface that octopussy has and it's feature list, but I am hesitant due to a few things. One of the biggest concerns I have is that it seems to be syslog only. The end goal is to have a centralized place for our devs and admins to be able to search through the logs generated by Apache, Tomcat and 70+ web apps spread out among a cluster, for both our prod and test environments. While I did see that octopussy has support for plugins, I haven't been able to find any sort of plugin repo or in depth guides as to what can be done with them. Does anyone know if plugins can be used to allow octopussy to non-syslog messages? Specifically log4j type log messages that may include multi-line stack traces and such. Also, is there a user community for this software, such as a mailing list or forum? I've been unable to locate any so far. Thank you.

• What Media Extender / Centre Set up should I use?

  - by Bryn Hird

  I have installed cat6 throughout the house which I use for telephony and network. In my cellar I have a NAS Server, gigabit switch and I want to install a Media Centre to stream my video's, music, photo's and live TV (coax from the aerial to the cellar) over the cat6. Yeah I know I can get stuff on the internet but shared experience of watching TV as a family as it happens is a big plus for live TV. I'm aiming for 1080p. I want different users to be able to watch different channels. Max users = 4. I've played a little with Windows Media Centre, works fine with live TV. Likewise I have XBMC up and running with live TV. The issue I have is what do I put near the TV. I'd like a consistent user interface (grandma and the the other technophobes in the house are continually pestering me on how to use different TVs, change channel, inputs etc.) so a key part of this for me is to make the user experience the same and simple i.e. no keyboards / PCs hanging around the TV. I've just bought a Linksys DMA 2200 to test the Windows Media Centre, but obviously off eBay as they're a dying breed. And with Windows Media Centre removed from Microsoft plans such devices will get rarer. And as for 1080p, think I can forget it with that set up. I have tested XBOX 360, also works but ditto on Microsoft plans for WMC. I was thinking of a WD Live TV to test the XMBC setup. Now to the question. Any advice on Media Centre / Extender setups that will do the job as above and have some degree of futureproofing (building my own with my Raspberry PI is a last resort). I'd like to understand the standards involved in the futureproofing if anyone knows (DNLA, RVU etc.).

• Different external ip addresses from different sites

  - by user630286

  My router is ClearOS 6(Centos 6). In my router, I have two external (internet) network connections from two ISP's. The primary connection is eth2 connected to a cable modem and the second one is ppp0 connected to a dsl modem. I have assigned eth2 as the primary connection (with a high metric value). In fact this is done through clearos's multiwan web interface. I have a test in my Nagios to monitor whether the primary connection. This connection is done based on the result of curl ifconfig.me But it seems that ifconfig.me is always giving the ip address of my secondary connection. I tested it through a browser. Yes ifconfig.me gives the secondary internet's(ppp0) ip address. But whatismyipaddress.[com|org] give my primary ip address (eth2). I checked the default route on the router through ip route list 0/0 which also shows the primary connection (eth2) as the default route. The traceroute www.google.com and traceroute ifconfig.me both seems to trace through the primary connection (eth2). As our secondary internet connection has only got a limited download, I don't want to end up having to pay a large sum at the end of the month. Has somebody got an idea why the ifconfig.me shows my secondary address? What is the best way to ensure that my router(and thus the lan) use the right internet connection.
