  • extra managed+unmanaged switches @ home/office -- best (mis)usage scenario? what would you do?

    - by locuse
    up front -- definitely NOT a mission-critical kind of question. after a 'spring cleaning' of my local office, i've ended up with two 'spare' GigE switches at my home/office -- one managed, capable of VLANs, QoS, etc, and the other unmanaged. i've got more ports than i need. in fact EACH switch has more total ports than i need. but, since i can't have these just sitting around not doing SOMETHING ... ;-) i'm interested in ideas for best combined use of these switches. my local topology is simple: [ net ] -- [ adsl2 modem ] -- [linux firewall/router/DNS ] _______________| | [ some arrangement of the 2 GigE switches ] | ( ... stuff on the lan ... ) [WAP1] [voip ATA] [printer] [desktop1] [mail server] [Xen server [desktop2] ( mostly dev, [desktop3] + file server [desktop4] + media server)] the MailServer is a production mail server the XenServer serves some low vol to the 'net; the MediaServer guest serves ONLY to the LAN is there, e.g., any performance value in segmenting off any of the LAN using the managed switch (VLAN? QoS tagging? something?), feeding the rest into the connected unmanaged switch? or should i simply use one of the switches & be done with it, and use the other for a coffee-cup stand?

  • wireless printer - entering WPA - is there a quicker way?

    - by camcam
    I have a wireless printer (Brother DCP-585CW). The wireless setup instruction says I should enter the WPA key to the printer. The key is entered using up and down buttons on the printer. So, I am supposed to enter 64 characters using up and down buttons. To enter 1 character, it takes on average (24+10)/2 = 17 times pressing the button (digits start after 24 letters). So 17*64 = 1088 times. Is there a quicker way to setup a wireless printer? Maybe there is a Windows program that discovers printers connected to computer through USB or Ethernet (my printer has both sockets) and allows to pre-configure it for wireless usage (enter the long WPA key)? Update There is BRAdmin program and it allows to set up almost all wireless settings... almost - all except WPA :(

  • All items in my pen drive had been renamed automatically and cannot open it

    - by pabz
    All the items (both files and folders) inside my pen drive had been renamed to some characters like :]h.¡?.A++ and when I try to open any folder Windows gives this message. The filename,directory name, or volume label syntax is incorrect I was told that it is a problem of the pen drive, not a virus. They say if I format the pendrive then I will be able to use it again normally. But I'm not sure. And I need those files. Does anybody knows a solution?

  • Enable (or work around) Administrative shares in Windows 8

    - by Brado
    So in using Windows 8, I've discovered that the administrative shares are disabled. There seems to be no easy way to get them re-enabled. Is anyone aware of a work around, or solution? I did not have this issue with Windows 7 After disabling UAC. However in Windows 8 this still doesn't work. This is all I could find, however I am not satisfied with the information provided. http://www.computerperformance.co.uk/win8/windows8-administrative-shares.htm http://www.tomsitpro.com/articles/windows_8-file_sharing-windows_administrative_shares,2-195.html

  • good books about server architecture?

    - by ajsie
    when the traffic for a website grows i dont think one apache server in a vps is the way to go. i would like to know more about how i then should set up the server side architecture. im not that much into hardware stuff (what kind of cables to use, different cpu architectures etc), but interested in the software architecture: what servers (apache, nginx, squid, varnish etc) to use and how they interact with each other one server in one machine? how many mysql servers. how many apache, nginx servers and so on. how the "machine court" looks like. are there any good books about this area?

  • Route outbound connections from local network through VPN

    - by Sharkos
    I have a server A running OpenVPN, an OpenVPN client B (a rooted Android phone as it happens) and a third party C (a laptop, tablet etc.) tethered to B. B can use the VPN to access the internet via A; C can use the tethered connection WITHOUT the VPN to access the internet via B. However, with the VPN on B active, I cannot load information from the internet on C. A appears to log similar traffic inbound and outbound when B or C attempt to load a webpage, say, but the VPN on device B reports no inbound traffic when the connection originated from C. Where should I look for packets being dropped, and what ip rules should I use to make sure they are passed back through the VPN and into the local network B <- C? (I'll obviously post whatever further information is needed.) Further info Without VPN: root@android:/ # ip route default via [B's External Gateway] dev rmnet0 [B's External Subnet] dev rmnet0 proto kernel scope link src [B's External IP] [B's External Gateway] dev rmnet0 scope link 192.168.43.0/24 dev wlan0 proto kernel scope link src 192.168.43.1 With VPN: root@android:/ # ip route 0.0.0.0/1 dev tun0 scope link default via [B's External Gateway] dev rmnet0 [B's External Subnet] dev rmnet0 proto kernel scope link src [B's External IP] [B's External Gateway] dev rmnet0 scope link [External address of A] dev tun0 scope link 128.0.0.0/1 dev tun0 scope link 172.16.0.0/24 dev tun0 scope link 172.16.0.8/30 dev tun0 proto kernel scope link src 172.16.0.10 192.168.43.0/24 dev wlan0 proto kernel scope link src 192.168.43.1 192.168.168.0/24 dev tun0 scope link

  • Is data=journal on a separate device on Ext4 as good as using a RAID controller with battery backed cache for file system consistency?

    - by Jeff Strunk
    It seems to me that data=journal prevents file system inconsistency in the case of power failure. Using it with a dedicated journal device mitigates the performance penalty of writing the data twice. A power outage would still lose the data that is currently being written to the journal, but the file system on disk would always be consistent. If that amount of loss is acceptable, is a RAID controller with battery backed cache really worthwhile?

  • Putting and configuring grub on an external drive

    - by HisDudeness
    I want to put a bunch of minor emergency operating systems (such as GParted Live, DSL, Puppy Linux and so on) on a partitioned USB pen drive, with a dedicated grub boot loader on it, which I want to start when I select the drive in the BIOS to boot. The problem is: when writing grub boot options I must tell where kernel and initial ram files are located, but the USB drive can have different letters depending on when I did plug it in, if some others external drive were mounted. So, how can I write appropriate options which automatically refer to the drive grub is installed on without having to specify absolute paths, which might change (I mean, like (hd1,msdos1) ot /dev/sdb1)? And, while we are at it, can I have grub working on a device without an operating system on it to which it can refer? I mean, I want to address the command sudo grub-install /dev/sdb from the LMDE system I'm on right now, but I won't have LMDE on my pen drive. Is that a problem? And installing grub on another device, will I keep the grub I have right now on my HDD?

  • securing communication between 2 Linux servers on local network for ports only they need access to

    - by gkdsp
    I have two Linux servers connected to each other via a cross-connect cable, forming a local network. One of the servers presents a DMZ for the other server (e.g. database server) that must be very secure. I'm restricting this question to communication between the two servers for ports that only need to be available to these servers (and no one else). Thus, communication between the two servers can be established by: (1) opening the required port(s) on both servers, and authenticating according to the applications' rules. (2) disabling IP Tables associated with the NIC cards the cross-connect cable is attached to (on both servers). Which method is more secure? In the first case, the needed ports are open to the external world, but protected by user name and password. In the second case, none of the needed ports are open to the outside world, but since the IP Tables are disabled for the NIC cards associated with the cross-connect cables, essentially all of the ports may be considered to be "open" between the two servers (and so if the server creating the DMZ is compromized, the hacker on the DMZ server could view all ports open using the cross-connect cable). Any conventional wisdom how to make the communication secure between two servers for ports only these servers need access to?

  • USB 3 to Gigabit Ethernet adapters: where are they?

    - by intuited
    I'm looking for an adapter that will let me use a USB 3 port as a Gigabit Ethernet port. This is proving surprisingly hard to find! Is there some reason why this product is either unavailable or very obscure? Is there an online shop (US/Canada) where I can buy such an item? Newegg, TigerDirect, NCIX, etc. do not seem to carry such an item. I find this surprising since it will provide at least double the bandwidth (possibly quadruple) compared to a USB 2 Ethernet adapter.

  • Disable the "smoke" in SmokePing for multihost

    - by Tuinslak
    Hey, I'm running SmokePing to monitor the latency to several machines. I have been playing around with the multihost feature, allowing me to draw stats of multiple machines in one graph. However, on the details page, smoke is being drawn as well, resulting in this: Is there a way to disable this? As it makes the graph pretty much unreadable. Smoke is enabled for the stats per server, so it's duplicated data here.

  • Do 7.2k SATA drives and a hardware raid controller always end with trouble?

    - by xelco52
    I'm reading the FreeNAS userguide and came across the statement: Note that hardware RAID configured as JBOD may still detach disks that do not respond in time; and as such may require TLER/CCTL/ERC-enabled disks to prevent drive dropouts. I'm using a '3Ware 9550SX-8LP RAID Controller' and see quite a few stories of people successfully running raid5 on 7.2k consumer SATA drives without issue. Are detached disks only a theoretical problem, or should I expect this to be a common occurrence?

Is it possible? OS: Ubuntu on both machines I tried this man (setting laptop2 wlan0 in ad-hoc mode): https://help.ubuntu.com/community/WifiDocs/Adhoc#Network_Manager laptop1 connects to laptop2, but can't access to internet.

  • A Single wireless network is not showing up in Ubuntu that used too, and other devices have no issue finding or connecting to it

    - by Kit Sunde
    Up until about a week ago I could connect to my wireless, but now I suddenly can't. Every other wireless in the area show up in the network manager. My kindle can connect to it, my friend can connect to it (in windows) without having connected to it before. My other netbook (Samsung NC10) can connect to it, but my other Samsung N150 now cannot even see it. I have tried deleting the old auto entry for it in the network manager Tried disabling and enabling both the networking and the wireless through the network indicator. Disabled the networking through the hardware shortkut key thing [fn] + [F9] Attempting to connect to it as if it was a hidden network. I'm at a loss, how would I go about debugging and unborking my computer?

  • Adding new virtual disks to a Windows host in ESX “live”

    - by warren
    Building on my previous question about RHEL, how do you add get the guest OS to recognize that you've added new drives to it without a reboot? I have Windows 2003, XP, and 2008 guests running on ESX 4. I've added new virtual disks to the VM, but have not figured-out how to get the guest to recognize them without a reboot. Is this possible? If so, how?
