• Reliable access to Internet but not local network (not DNS or proxy issues)

  - by Ian Goldby

  I'm looking for help with a Vista Home Premium laptop that has trouble accessing any resource on our home network, but accesses the Internet just fine. The set-up is this: The Vista laptop and a MacBook Pro connect wirelessly to the router-modem. A Synology DS212j NAS drive has a wired connection to the router-modem. Devices on the local network are always referred to by IP address, so this cannot be a DNS issue. The MacBook Pro connects reliably to the NA via AFP (network shared folders), SMB (network shared folders) and HTTP. The Vista laptop connects to and browses sites on the Internet without any problems. It can log into the NAS via SMB and list the shared folders (so there is nothing wrong with the log-in credentials), but when it tries to open any of the folders Explorer just hangs with the spinning cursor for several minutes and then says "\192.168.1.64\shared\Photos is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network name is no longer available." It can ping the NAS successfully. If I try to open the NAS drive's web interface, the browser just hangs. This is the same with IE, Firefox and Chrome. (There is no proxy.) I can log into the NAS drive with FTP and navigate directories, but when I try to list the contents of a directory with more than a handful of entries, the ftp client hangs. I set up a website on the MacBook. The Vista laptop was able to load some of the pages, but loading any of the images was very hit and miss. Images embedded in HTML pages never worked no matter how many times I reloaded the page, but when I linked directly to the image it did load (though several attempts were sometimes needed). I tried all of this with the Windows Firewall turned off, and with AVG turned off. That made no difference. I'd really appreciate any suggestions anyone can make. The fact that the Vista laptop has trouble with HTTP and FTP as well as SMB connections suggests to me that this is a problem at the TCP level or below. But don't forget it accesses sites outside the LAN with no problems.

• Possible to migrate from non-RAID to RAID 1 and then RAID 5?

  - by stueng

  Using software RAID only Is it possible to start with a 2TB disk full of data and safely add it to a RAID 1 array? Is it then possible to add a third disk and migrate the RAID 1 array into a RAID 5 array? OR Is it possible to start with a 2 disk degraded RAID 5 array and then add the third disk later to create a health RAID 5 array? Backstory: I wish to migrate from a 2 disk NAS (RAID 1) to a 3 disk NAS and only purchase one new disk in doing so

• mounted smb share throu fstab, gets read only on added files

  - by Jocke

  I mounted my nas in ubuntu 12.10 and it works with read/write, but when I'm adding a file or directory that file gets read only permissions. My fstab mount looks like this: //192.168.0.12/share/ /media/nas cifs credentials=/home/jocke/.smbcredentials,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0 If I mount the smb share manualy through the GUI it works, but not through fstab.

• configure a Cisco ASA to use MS-CHAP v2 for RADIUS authentication

  - by DrStalker

  Cisco ASA5505 8.2(2) Windows 2003 AD server We want to configure our ASA (10.1.1.1) to authenticate remote VPN users through RADIUS on the Windows AD controller (10.1.1.200) We have the following entry on the ASA: aaa-server SYSCON-RADIUS protocol radius aaa-server SYSCON-RADIUS (inside) host 10.1.1.200 key ***** radius-common-pw ***** When I test a login using the account COMPANY\username I see the users credentials are correct in the security log, but I get the following in the windows system logs: User COMPANY\myusername was denied access. Fully-Qualified-User-Name = company.com/CorpUsers/AU/My Name NAS-IP-Address = 10.1.1.1 NAS-Identifier = <not present> Called-Station-Identifier = <not present> Calling-Station-Identifier = <not present> Client-Friendly-Name = ASA5510 Client-IP-Address = 10.1.1.1 NAS-Port-Type = Virtual NAS-Port = 7 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = <undetermined> Policy-Name = VPN Authentication Authentication-Type = PAP EAP-Type = <undetermined> Reason-Code = 66 Reason = The user attempted to use an authentication method that is not enabled on the matching remote access policy. My assumption is that the ASA is using PAP authentication, instead of MS-CHAP v2; the credentials are confirmed, the proper Remote Access Policy is being used, but this policy is set to only allow MS-CHAP2. What do we need to do on the ASA to make it us MS-CHAP v2? In the ADSM GUI The "Microsoft CHAP v2 compatible" tickbox is enabled, but I don't know what this corresponds to in the config.

• VPN Error 691 but server says authenticated on server

  - by Andy

  Hello all, I have a problem with a vpn connection on Windows XP SP3 that appears to be related to an account (maybe privilleges or an option that I have missed). When connecting using my account, which is a domain administrator account it will connect to through the vpn fine. However, using an account created for another person they receive Error 691: Username or Password is not valid for this domain. On the domain controller (windows 2003) I see a logon successful message: User DOMAIN\user was granted access. Fully-Qualified-User-Name = int.company.net.au/People/Management/User NAS-IP-Address = 10.30.0.3 NAS-Identifier = not present Client-Friendly-Name = MelbourneCore Client-IP-Address = Router-ip Calling-Station-Identifier = not present NAS-Port-Type = Virtual NAS-Port = 77 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = undetermined Policy-Name = Remote VPN Access Authentication-Type = MS-CHAPv1 EAP-Type = Does anyone have any ideas as to where else I should look for finding a solution? If i use the wrong password it gives a logon failure error in the event viewer. Also removing them from the remote access group gives a logon failure error. Nothing appears in the event viewer on the local machine. In the past all that is required is to add them into our Remote Access Users group. Any help?

• Time-Machine backup over SSH tunnel to NFS mount

  - by BTZ

  I've recently started using a new NAS which runs CentOS 6.2. One of the purposes of the NAS would be to serve as a backup target. Whilst I have been using Apple's Time-Machine for a while and I am very satisfied with it, I'd like to continue using it. Backing up directly to an address in my network is no hassle; all works fine. For security reasons I'd like all my traffic to go through an ssh tunnel to the NAS. This way I can avoid needing to get a VPNserver (for personal reasons). As of NFSv4 the NFS deamon is bound to port 2049, which makes it easy for me to direct all traffic through a ssh tunnel. Tunnel: ssh -f admin@ms -L 2000:localhost:2049 -N Mount: mount -t nfs -o nfsvers=4,rw,proto=tcp,sync,intr,hard,timeo=600,retrans=10,wsize=32768,rsize=32768,port=2000 localhost:/mac_backup /Volumes/backup This works fine for Finder/terminal and throughput is almost equal to direct traffic. (CPU of the NAS does ride high when I reach max bandwidth though) Now the problem: With Time-Machine I can't use the NFS mount point mounted on localhost. TM seems to try to connect to it and then give me a "OSStatus error 65". I also tried using NFSv3 (I correctly forwarded all ports) with no luck. Can anyone shed a light on this and/or give a solution?

• Shared storage solution for our sql server backups

  - by Gokhan

  We have 3 clustered sql servers. We have 5+ multi terrabyte databases and their backup files (compressed using quest litespeed) are hitting over 600gb each, We are required to keep at least a week or two weeks (if we can) of weekly full backups and then 6 days differential backups, and a week or 2 weeks worth of log backups local. We are currently limited to 2TB volumes from our san team, we can have multiple volumes but they are expensive ($200 per raw TB per month) and having to deal with many backup volumes instead of a single big volume is difficult. I think if we could have a shared network storage of 20TB+ raid 10 or so for all our servers for keeping the backups and another department will copy them to tape from the network storage and delete files according to the retention period would be good, if this box would be a build in operating system (even unix a complete file storage system) that would be good. What do you guys think, does this make sense to you, is there any manufacturer that sells a storage product like that which that work in a clustered environment? Thank you

• How to configure network on Windows Server 2008

  - by Gokhan Ozturk

  I have a IBM x3400 Server Machine with Windows Server 2008 R2 installed on it. But, since I am not expert on networking I have some problems. These roles installed on my server: Active Directory DNS File Sharing Hyper-V ISS VPN There is two network card on them. I configured them like this: Local Connection 1: 192.168.30.3 255.255.255.0 192.168.30.2 127.0.0.1 Local Connection 2: 192.168.30.101 255.255.255.0 192.168.30.6 127.0.0.1 My problem is, when I use this Ip gateways, It is sharing internet to all computers. This is not I want. I want to use Local Connection 1 for internal network. I am giving all computers gateway and DNS IP as 192.168.30.3 The Local Connection 2 is for Hyper-V and VPN connections. 192.168.30.2 and 192.168.30.6 are my modem's gateways. I am using 192.168.30.6 external IP for VPN connections. There is two 24 port switches. There is a connection between them and this two ethernet card connected directly to them. And modems are connected to switches as well (Morems are not near the server. They are somewhere in the building). I disabled network Bridge and removed all ethernet cards from it. With this configuration, all computers can ping my server's IP (192.168.30.3) but on server I cannot ping any clients (Request timeout). What is the best way to configure my network? Thank you.

• Can ZFS ACL's be used over NFSv3 on host without /etc/group?

  - by Sandra

  Question at the bottom. Background My server setup is shown below, where I have an LDAP host which have a group called group1 that contains user1, user2. The NAS is FreeBSD 8.3 with ZFS with one zpool and a volume. serv1 gets /etc/passwd and /etc/group from the LDAP host. serv2 gets /etc/passwd from the LDAP host and /etc/group is local and read only. Hence it doesn't not know anything about which groups the LDAP have. Both servers connect to the NAS with NFS 3. What I would like to achieve I would like to be able to create/modify groups in LDAP to allow/deny users read/write access to NFS 3 shared directories on the NAS. Example: group1 should have read/write to /zfs/vol1/project1 and nothing more. Question The problem is that serv2 doesn't have a LDAP controlled /etc/group file. So the only way I can think of to solve this is to use ZFS permissions with inheritance, but I can't figure out how and what the permissions I shall set. Does someone know if this can be solved at all, and if so, any suggestions? +----------------------+ | LDAP | | group1: user1, user2 | +----------------------+ | | | |ldap |ldap |ldap | v | | +-----------+ | | | NAS | | | | /zfs/vol1 | | | +-----------+ | | ^ ^ | | |nfs3 |nfs3| v | | v +-----------------------+ +----------------------------+ | serv1 | | serv2 | | /etc/passwd from LDAP | | /etc/passwd from LDAP | | /etc/group from LDAP | | /etc/group local/read only | +-----------------------+ +----------------------------+

• Recover data from hard drive with partitions (but not most data) overwritten

  - by Macha

  I have a 500GB hard drive I've been keeping around to recover data from that I removed from a failing NAS drive that got sort of... erratic at the end. I finally got rid of the NAS when during a firmware update it removed the partition table. Fast forward to a week ago, when I was building a new PC, and a mixup resulted in me placing the hard drive in question in the new PC and installing Windows XP on the first 100GB. I'm presuming any data on that first 100GB is now gone, but for the rest of it, is there any way I can recover it at home, as professional data recovery is currently too expensive? I have a blank 1TB HDD if I can store any images of that hard drive on. The problem was definitely with the NAS and not the hard drive, as the hard drive had a successful install of Windows when mistakenly place in the new PC, and there were capacitors in the NAS's circuitry clearly broken. The data I want to recover (in order of priority) is: High: Some jpgs of family photos. Medium: Some RAW files. (There are also jpg versions of all of these) Low: Some mp3s, avis and ISOs, I can re-rip most of these if need be, but it'd be handy not to have to. (I don't need a backup lecture, and if you can hold it in from nagging Jeff Atwood for it, you can hold it in from nagging me for it) In short: The partition tables are gone and overwritten. The data is not overwritten, except for an amount equal to the size of a Windows XP SP3 installation.

• Expand a volume residing on one X-RAID disk installed on a Netgear ReadyNas Duo v2

  - by Sid

  I've got a Netgear ReadyNas Duo v2 (2 disk slots). System is configured with X-RAID which does not provide flexibility but automatically expands based on a sort of RAID-5 logic. I had 2 500 GB hard disk installed, redundant, so I had 500 GB of volume size. I wanted to upgrade the whole system to 3 GB * 2 hard disk maintaining both the data already on the NAS and the data on one of the two 3 TB hard disks. So I did this: Unplugged one disk from the ReadyNas. Now the readynas has 1*500 GB non redundant. Plugged one empty 3 TB hard disk. Now the readynas has 1*500 GB + 1*3 TB, redundant. I waited for the resync. I then unplugged the 500 GB hard disk, so that I have only the 3 TB hard disk with the previous data. Now what I want is to copy the data on my other 3 TB hard disk in the NAS, so that I can plug this other disk in the NAS and use it for redundancy. The problem is that: the NAS has the (single) 3 TB hard disk in X-RAID, but the volume does not expand to 3 TB, it remains fixed to 500 GB. Is there a way to tell the ReadyNas to force expanding the volume to the whole disk without plugging in another hard disk of the same size?

• SSH tunneling with Synology

  - by dvkch

  I try to tunnel SMB and AFP services through SSH to acces my NAS shares on my machine. I already do it successfully with my ReadyNAS using the following command line (ran as my user on my mac) : ssh -Nf -p 22 -c 3des-cbc USER@SERVER -L 8888/127.0.0.1/548 -L 9999/127.0.0.1/139 but I cannot reproduce the same with the Synology NAS. Connecting using this command gives me the following error : channel 4: open failed: administratively prohibited: open failed I also tried with a windows client (used bitvise tunneler): it works with the ReadyNAS but not the Synology and get the following error msg : server denied request for client-side server-2-client forwarding on 127.0.0.1:139 I modified /etc/ssh/sshd_config : MaxSessions 10 PasswordAuthentication yes PermitEmptyPasswords no AllowTcpForwarding yes GatewayPorts yes PermitTunnel yes Is there any way to make it work ? I must add that I can successfully connect via SSH to the NAS so I donnot think this is a firewall issue between the Synology and my computer. Thanks for you answers

• ODF (Open Document Format) para ISVs - 16/Dez/10

  - by Paulo Folgado

  Os ISVs (Independent Software Vendors) sentem frequentemente necessidade de incluir nas suas aplicações uma funcionalidade de exportação de informação - uma carta, uma tabela com dados financeiros, um gráfico, etc - para que possa ser trabalhada externamente com ferramentas ditas de Produtividade num 'desktop' (também designadas por 'Suites de Office'). Nessas situações são confrontados com a necessidade de elegerem que formato deve ser usado para essa exportação de dados, sendo a escolha mais usual a utilização dos formatos do Microsoft Office. Contudo, se fôr essa a sua única opção, estarão a auto excluir-se de um mercado em crescimento constituído pelos clientes que utilizam outras ferramentas de produtividade, nomeadamente as que são baseadas no standard ISO Open Document Format (ODF), como é o caso do Open Office. Este seminário tem por objectivo dar aos parceiros ISVs da Oracle: Uma visão sobre o mercado actual de 'suites' de Office e dos standards usados pelos principais fornecedores de soluções A estratégia da Oracle para o Open Office Razões para deverem suportar a norma ODF Como suportar ODF nas suas aplicações Agenda O mercado actual das Suites Office Os standards actuais "de facto" e oficiais - MS-Office, OOXML e ODF Que produtos usam o ODF hoje Estratégia Oracle para o Open Office Porquê suportar ODF nas aplicações Como adaptar as aplicações actuais à utilização de ODF Local: Oracle - Lagoas ParkData: 16 de DezembroDuração: 1/2 diaHorário: 9:30 - 12:00 Inscrições: Email, ou pelo telefone 211929708 Para mais informações, por favor contacte Claudia Costa via Email ou telefone 214235027.

• How to establish SIP connection, when SIP-proxy is required?

• Put a Windows computer to sleep remotely (from a Linux box)

  - by snark

  I'd like to have my Linux box (a QNAP TS-210 NAS) send the order to go to sleep (or hibernation) to my main Windows 7 computer. As the NAS is running Linux, I can't use psshutdown from SysInternals' PsTools. Is there any Linux equivalent? Or some "magic packet" that can order the Win7 computer to sleep. I know I could install a SSH daemon and trigger a shutdown command from the Linux box using ssh, but ideally I do not want to install anything on the Win7 computer. I can install Linux software on the NAS, no problem about this. PHP, python and perl are also available on it.

• Why do I have only incoming traffic when copying from network source to network destination?

  - by mxp

  I have a VirtualBox VM that is located on a network share of my NAS. When I copy something from the VM's disk onto another of the NAS' network shares (so the data is visible outside the VM), the Windows 7 Task Manager shows only incoming network traffic (yellow graph). It's as if the data was only received but never sent over the network. I verified that the data arrives on the other network share. As I understand it, the data flow looks like this: +-NAS--------+ +-Win7 PC (VM Host)-+ | Share1(VM)-|>---->|-+ | | | | | | | Share2 <---|<----<|-+ | +------------+ +-------------------+ If it was like this, I would see incoming and outgoing traffic, right? What am I not getting here?

• How to mount private network shares on login?

  I've read all the existing entries I could find on using pam_mount but none of them seem to work for me. I'm trying to automatically mount shares on my local NAS at user login time. The usernames and passwords on my NAS shares match my local user name and password, but there is no LDAP/AD server. My pam_mount.conf has the following: <volume fstype="cifs" server="bain-brain" path="movies" user="*" sgrp="bains" mountpoint="/home/%(USER)/movies" options="user=%(USER),dir_mode=0700,file_mode=700,nosuid,nodev" /> When I login, I see the following in /var/log/auth.log: Oct 13 10:21:26 bad-lattitude lightdm: pam_mount(misc.c:380): 29 20 0:20 / /home/alastairb/movies rw,nosuid,nodev,relatime - cifs //bain-brain/movies rw,sec=ntlm,unc=\\bain-brain\movies,username=alastairb,uid=1000,forceuid,gid=1000,forcegid,addr=10.1.1.12,file_mode=01274,dir_mode=0700,nounix,serverino,rsize=61440,wsize=65536,actimeo=1 The folder /home/alastairb/movies is present but empty (can't see the files which are on the NAS in the respective share folder). In Nautilus, the share is shown in the sidebar under "Computer", and clicking on this takes me to the correct folder, but again, its empty. Any ideas as to what I'm doing wrong?

• How can I boot a vm on Hyper-V 2012 when it has a virtual hard-drive missing?

  - by Zone12

  We have a Hyper-V 2012 server with 8 VM's on. We have attached extra virtual hard-drives to each of the computers to store backups on. These drives are stored on a NAS. After a power failure, we tried to boot the VM's and found that they couldn't be booted without the attached backup drives. We couldn't boot the NAS at that point and so we had to remove all the extra drives manually, boot the VM's and re-attach the drives at a later date when we got the NAS back up and running. These backup drives are non-essential to the running of the system. I would like to know if there is a way to boot a VM on Hyper-V 2012 with some of the hard-drives (scsi) missing so that we can recover automatically from a power failure.

• Virtualized data centre&ndash;Part three: Architecture

  - by marc dekeyser

  Having the basics (like discussed in the previous articles) is all good and well, but how do we get started on this?! It can be quite daunting after all!   From my own point of view I can absolutely confirm your worries and concerns, but also tell you that it is not as hard as it seems! Deciding on what kind of motherboard to buy, processor and how much memory is an activity you will spend quite some time doing research on. And that is not even mentioning storage! All in all it comes down to setting you expectations and your budget. Probably adjusting your expectations according to your budget :). Processors As a rule of thumb you want VT-D (virtualization) technology built in to the processor allowing you to have 64 bit machines running on your host. Memory The more the better! If you are building a home lab don’t bother with ECC unless you are going to run machines that absolutely should be on all the time and your comfort depends on it! Motherboard Depends on what you are going to do with storage: If you are going the NAS way then the number of SATA port/RAID capabilities do not really matter. If you decide to have a single server with lots of dedicated storage it obviously matters how much SATA ports you will have, alternatively you could use a RAID controller (but these set you back a pretty penny if you want one. DELL 6i’s are usually available for a good bargain if you can find one!). Easiest is to get one with a built-in graphics card (on-board) as you are just adding more heat, power usage and possible points of failure. Networking Just like your choice of motherboard the networking side tends to depend on how you want to go. A single virtualization  host with local storage can usually get away with having a single network card, a cluster or server which uses iSCSI storage tends to have more than one teamed up :). Storage The dreaded beast from the dark! The horror which lives in the forest! The most difficult decision you are going to make in the building of your lab. Why you might ask? Simple my friend, having the right choice of storage can make or break your virtualization solution. The performance of you storage choice will have an important impact on the responsiveness of your virtual machines and the deployment of new machines. It also makes a run with your budget! If you decide to go the NAS route you will be dropping a lot more money than if you would be having just a bunch of disks sitting in a server and manually distributing the virtual machines over the disks. Platform I’m a Microsoftee so Hyper-V is a dead giveaway for me. If you are interested in using VMware I won’t stop you but the rest of my posts will be oriented on Server 2012 Hyper-V (aka 3.0)! What did I use? Before someone asks me this in the comments I’ll give you a quick run down of what I am using. - Intel 2.4 quad core processors (i something something) - 24 GB DDR3 Memory - Single disk in each server (might look at this as I move the servers to 2012) - Synology DS1812+ NAS - 3 network interfaces where possible - HP1800 procurve managed switch I decided to spring for the NAS as I will also be using it for backups and media storage (which is working out quite nicely with my Xbox 360 I must say). At the time of building my 2 boxes (over a year and a half ago) these set me back about 900 euros each so I can image you can build the same or better for a lower price. Next article will be diagramming what I want to achieve and starting a build on the Hyper V 3.0 cluster!

• WTK emulator bluetooth connection problem

  - by Gokhan B.

  Hi! I'm developing a J2ME program with eclipse / WTK 2.5.2 and having problem with connecting two emulators using bluetooth. There is one server and one .client running on two different emulators. The problem is client program cannot discover any bluetooth device. Here is the server and client codes: public Server() { try { LocalDevice local = LocalDevice.getLocalDevice(); local.setDiscoverable(DiscoveryAgent.GIAC); server = (StreamConnectionNotifier) Connector.open("btspp://localhost:" + UUID_STRING + ";name=" + SERVICE_NAME); Util.Log("EchoServer() Server connector open!"); } catch (Exception e) {} } after calling Connector.open, I get following warning in console, which i believe is related: Warning: Unregistered device: unspecified and client code that searches for devices: public SearchForDevices(String uuid, String nm) { UUIDStr = uuid; srchServiceName = nm; try { LocalDevice local = LocalDevice.getLocalDevice(); agent = local.getDiscoveryAgent(); deviceList = new Vector(); agent.startInquiry(DiscoveryAgent.GIAC, this); // non-blocking } catch (Exception e) {} } system never calls deviceDiscovered, but calls inquiryCompleted() with INQUIRY_COMPLETED paramter, so I suppose client program runs fine. Bluetooth is enabled at emulator settings.. any ideas ?

• Making all variables accessible to namespace

  - by Gökhan Sever

  Hello, Say I have a simple function: def myfunc(): a = 4.2 b = 5.5 ... many similar variables ... I use this function one time only and I am wondering what is the easiest way to make all the variables inside the function accessible to my main name-space. Do I have to declare global for each item? or any other suggested methods? Thanks.
