• Performance of Cluster Shared Volume file copy from SAN

  - by Sequenzia

  I am hoping someone can help me out with a strange issue. We are running a Microsoft Failover Cluster with Server 2008 R2 and an Equallogic PS4000 SAN. Our main configuration has 2 Dell Poweredge T710 Servers in the cluster. We have CSV and Quorm setup. The servers each have 10 Broadcom 1Gb NICs. Right now 4 of the NICS are on the iSCSI network for accessing the SAN. They use MPIO and the Dell HIT pack. We have 5 VMs running on each node and everything runs smooth. No noticeable performance issues or anything. From the SAN I can see the 4 iSCSI connections from each server to each volume (CSV and Quorm). Again, it seems to perform great. The problem I am running into is with backups. I have tried a few backup programs like backupchain and Veeam. The problem is both of them are very very slow to backup the VMs. For instance I have a 500GB (fixed disc) VHD that’s running on the cluster. It takes over 18 hours to backup that VHD and that’s with compression and depuping turned off which is supposed to be the fasted. We also have a separate server that is just for backups. It has a lot of directed attached storage. As part of the troubleshooting I decided to bring that server into the cluster as a node. It now has access to the CSV and can read from C:\clusterstorage\volume1 which is where our VHDs live. This backup server only has 2 NICs. 1 NIC is going to the iSCSI network and the other is just on the main network. It has Intel NICS in it without any sort of MPIO or teaming. So with the 3rd server now in the cluster I started doing some benchmarking. I have a test VHD that’s about 7GBs that’s stored in the CSV. I have tested file copying that VHD from all 3 servers to directed attached storage in the respective server. The 2 Dell servers that are the main nodes in the cluster (they house the VMs) are reading that file at about 20Mbs/Sec. Which at that rate is way to slow for the backups. The other server which only has 1 NIC to the SAN is reading at around 100Mbs/Sec. I spent a few hours on the phone with Dell today about this . We went through all kind of tests and he was pretty dumb founded. He really has no idea why that server with only 1 NIC is reading about 5 times as fast as the servers with 4 NICS and MPIO. We looked at the network utilization of the NICs while the file copy was going on. The servers with the 4 NICs had a small increase of activity during the file copy but they only went up to around 8-10% on all 4 NICs. The other server with the 1 NIC jumped up to over 80% during the file copy. I plan on doing some more testing after hours and calling Dell back tomorrow but I really am confused (and so is Dell’s support rep) why I cannot get faster file copy access to the CSV on those servers. Anyone have any input on this? Any feedback would be greatly appreciated. Thanks in advance.

• IIS: changing site's home directory while site is running

  - by Jeff Stewart

  I'm trying to understand exactly what IIS 6.0 (on Windows Server 2003) does when I change the "Local Path" of a web site's Home Directory while the site is running. (Specifically with regard to ASP.NET applications.) I'm trying to build support for or against this practice in a deployment scenario: e.g. deploy the new code alongside the old code, then simply switch the IIS web site's local path to the folder containing the new code. IIS seems to handle this gracefully, but I notice that w3wp.exe still keeps some handles on the old code folder after the change. That's strange to me, because I would have expected IIS to recycle the application pool if this happened. Is this safe? Is the behavior well-defined?

• Choice of an OS for a home ZFS NAS

  - by OlafM

  I am preparing a home NAS with an old Athlon 64 X2 3800+, 4 GB ECC RAM, Asus M2V MX motherboard, and a single 3 TB WDC Green (another one as mirror may be installed in the future). It's the cheapest solution I found that includes ECC memory and the higher energy consumption is offset by the lower (zero) cost of acquisition. The system will be used for: music storage and stream to other desktop computers; storage of the scanned dia slides (3-4k slides, 180 MB TIFF each one plus reduced quality JPEG version); stream of these photos to a local iPad 2 (maybe Plex App? not yet sure); (one additional) remote backup via rsync/ssh or ZFS send/receive. It will be controlled via remote ssh, maybe VNC, no monitor attached. Absolute requirement is a reliable ZFS solution, plus the ability to easily install packets/software/virtual machines and to update remotely (I will be the admin and I don't live near the NAS). I have mainly three options: NAS4free/FreeNAS OpenIndiana Solaris Express 11 (yeah yeah I know the license requirements, I will write a perl script on it to count it as development machine). Problems: NAS4free/FreeNAS (I tested only NAS4free) required embedded installation for remote upgrading, but full install for easy addition of software packets. Since I need at least AirVideo Server (linux/win) and Plex App (win/linux) to stream the photos and some videos to iPad (they both require virtualbox), but I cannot be there to install updates, NAS4free/FreeNAS are excluded. http://www.nas4free.org/general_information.html explains the issue: embedded can be remotely updated, full cannot. Solaris has also another advantage: Crashplan client supports Solaris and I'm already using it for other backups. I would like to leave the option open, even if I will be doing backups probably through zfs send/receive. NexentaStor was left out because zfs send/receive are not included in the free version. The question is now Solaris 11 Express over OpenIndiana. To ease the management, I will be using http://www.napp-it.org Which one would you suggest and why? I found lots of informations and it's difficult for me to decide. I think (from the napp-it manual) that Solaris has some additional options for SMB shares, but are they really needed at home? I think I won't even use ACLs, since normal unix-style permissions are enough. OpenIndiana has maybe more frequent updates (Solaris offers only security updates between releases), but again, do I need them? I don't think so. Moreover, this is a NAS that has to work and nothing else, I cannot risk having problems that require me to access the server. Isn't OpenIndiana a bit more... cutting edge (in the Solaris world)? I'm just asking, no need to focus on this for the answer :-) I would limit myself to these two options (SE11.1/OI) also because I will be making a NAS for me in the future (where high performances with Mac shares are also required) and Solaris has kernel support for AFP. I will use this server to gather experience as well. After this long question, thanks in advance! If you need additional info, let me know and I will update this post.

• Picture syncing on Multiple Macs, iPhones, and iPad together so each device can update them all

  - by cohortq

  Hello! One of the owners of my company has put me to task to sync his pictures between the following devices together. (2) iPhones (2) iMacs (1) Macbook Air (1) iPad Here is what is happening 1) He has a camera that can upload pictures into iPhoto in either (1) of his iMacs, or Macbook Air. 2) He has (2) different iPhones. And here are how they are paired up iPhone - iMac Home iPhone - Macbook Air 3) He has MobileMe syncing Calendar, Contacts, and Notes across all devices 4) Currently we are using MobileMe web galleries to sync all photos, by having ME create each album and upload them to the MobileMe web gallery. Not the problem is. He wants to just take pictures, and once he does that it syncs with all his devices, he'll even dock the iPad. Is there a better way to sync photos between all devices?

• Configuring Mail Relay

  - by ServerChecker

  I'm running Ubuntu Server 9.10 with Postfix and Webmin. I have created virtual hosts for 3 domains following this serverfault.com answer. But the mail isn't relaying out to the world. I have 3 domains tied into my DNS in webmin, as well as inside DNS clicked Mail Server and followed that instruction using this article on the web. The domains and the web servers work just fine. I also have FTP working just fine. So, the remaining problem I have is mail. Can't forward mail out to a Gmail account for some reason. Note I'm just trying to do the "easy version" of Postfix config and if your answer is in Webmin-ease, that would help me. However, I can edit a text file if you suggest.

• Can I use Zoneedit to do URL rewrite?

  - by chilly-child

  This is our scenario: Our DNS is hosted by a company. They don't manage the DNS. We use Zoneedit (www.zoneedit.com) to manage the DNS such as nameservers, CNAMEs, etc... Then we have our web host where we just have our files hosted. We have a subdomain created on zoneedit. We would like to do a URL rewrite so that subdomain.ourdomain.com is displayed as www.ourdomain.com/subdomain. Do I use Zoneedit to do the URL rewrite or the web host or the DNS host? I checked the Zoneedit docs but I could not find a way to do a URL rewrite. Need some advice. Thanks

• Run Python Server at Startup

  - by DizzyDoo

  Hello, I've got a few Python based servers that I need to run, and would like them to start automatically when I start my Ubuntu Server box. What is the best way to execute them like this? I was hoping I could write a Bash script and use Screen to get them running in the background, where I can check on them every now and then, but where as echo screen -d -m python works just fine, echo screen -d -m `sudo python /home/matt/tornadoServer/tornadoDeploy.py` doesn't, with no error messages. Is that something to do with the spaces? Even though I did surround it with backquotes? I also tried: WEB="screen -d -m `sudo python /home/matt/tornadoServer/tornadoDeploy.py`" echo $WEB As a way of escaping the spaces, but no luck. What's Bash scripting way to do this? And, once the Bash script works, where can I put it to make it execute on startup?

• Tie stock quote value to cell in Excel 2011 Mac

  - by vedantchandra

  I've been working on a mock stock portfolio in Excel, and I've been looking for ways to automatically update the data, eg. stock price and P/E ratio. I have tried using a web query to MSN Money, but that just brings up the whole stock quote across multiple cells, I want data to be updated in individual cells only. The only web query solution I can think of is if someone hosted a website where each value in the stock quote was saved on a different HTML file. I could then WebQuery to that file for each cell requiring that value. However, no website offers this. So in essence, is there any tool on Excel 2011 Mac that will let me pull individual values from a stock quote and assign them to a single cell?

• Why might one host be unable to access the Internet, when it can ping the router and when all other hosts can?

  - by user1444233

  I have a Draytek Vigor 2830n. It's kicking out a 192.168.3.0 LAN. It performs load-balancing across dual-WAN ports, although I've turned off the second WAN to simplify testing. There are many hosts on the LAN. All IPs are allocated through DHCP, most freely allocated from the pool, but one or two are bound to NIC MAC addresses. All hosts can access the Internet, save one. That host (192.168.3.100 or 'dot100' for short) gets allocated an IP address (and the right gateway address, DNS server addresses, subnet etc.) dot100 can ping itself. It can ping the gateway, and access the latter's web interface via port 80. It's responsive and loss-free (sustained ping over a couple of minutes reports no data loss). Yet, for some reason that evades me, dot100 can't ping an external IP address or domain name. I suspect it's never been able to, because it was getting some Internet access from a second adaptor (different subnet), but that's now been turned off, which exposed the problem. In dot100, I've tried: two operating systems (Windows 8 and Knoppix), to rule out anti-virus programs etc. two physical adaptors two cables, on each adaptor two IPs (e.g. .100 and .103 assigned by Mac and .26 from the pool) both dynamic and assigned (MAC-bound) DHCP-allocated IPs but none of this experiments yielded any variation in the result. dot100 is a crucial host. It's a file server for the network, so I need it to be reliably allocated a consistent IP. Can anyone offer a potential solution or a way forward with the analysis please? My guess My analysis so far leads me to believe it's a router issue. I've checked the web interface very carefully. There are no filters setup in Firewall - General Setup or Filter Setup. I suspect it's a corrupted internal routing table, but the web UI shows this as the Routing table: Key: C - connected, S - static, R - RIP, * - default, ~ - private * 0.0.0.0/ 0.0.0.0 via 62.XX.XX.X WAN1 * 62.XX.XX.X/ 255.255.255.255 via 62.XX.XX.X WAN1 S 82.YY.YYY.YYY/ 255.255.255.255 via 82.YY.YYY.YYY WAN1 C 192.168.1.0/ 255.255.255.0 directly connected WAN2 C~ 192.168.3.0/ 255.255.255.0 directly connected LAN2

• How does geolocation based on IP address work?

  - by Martin

  As all Internet users, I've visited web sites which appear to know in which country and city I'm located. I understand that these web sites typically look up my IP address in a database which maps IP address to country / city which works fairly well. I've also seen companies selling this type of database. How is this database, which maps an IP address to a country / city, created in the first place? Is there a central database somewhere where each ISP registers the link between IP address and country/city? Or does the companies selling geolocation databases contact different ISP's and purchase the mapping information from them? Or is there some organization 'above' ISP's who keeps track of this?

• A different interface for the Sql Server Reporting Service?

  - by AngryHacker

  I have a SQL Server 2005 SQL Reporting Services implementation. It seems that the only way to actually access the reports is for the users to use Internet Explorer. The web page uses an ActiveX control to do its printing (and probably other functions as well). Does SSRS have a different way to access its functionality via the web browser? Like maybe Java or HTML based? If so, how do I actually turn it on? The reason I am asking is because the security is being tightened and ActiveX controls will be banished, thus the users won't be able to print.

• LDAP for privilege control?

  - by neoice

  I've been wondering for a while if LDAP can be used to control user privileges. For example, if I have UNIX and web logins, is there an easy way to grant a user access to just or just UNIX (or even both?) My current attempt at solving this very problem was to create 'login' and 'nologin' groups, but this doesn't seem fine-grained enough to meet the ideas I have in my head. I'm also still in the situation where all UNIX users are web users, which isn't a problem so much as an indicator of the limitations. Does anyone have any input on this? Has this problem already been solved?

• Windows Server 2008 Antivirus Software with an API

  - by Dave Jellison

  I'm looking for an Antivirus package that is compliant with Windows Server 2008. That's not the hard part. What I need is an API layer on the Antivirus that i can call from managed .net code. For example: I am developing an Asp.Net (C#) website that allows users to upload files to the web server which the web site resides on. We have full control of the server so there are no security/rights issues on the server. I need to be able to run the antivirus algorithm on the newly uploaded files without (hopefully) shelling out to a command-ilne version of the software. Does anyone know of such a package?

• NLB RPC server is unavailable on the specified computer

  - by Robin Weston

  Hi guys, Firstly, I'll admit that my networking knowledge is limited so as people request more information I'll update this question accordingly. I am trying to create a NLB Cluster across 2 Windows Server 2008 Web Servers. Neither of the machines are members of a domain, and both have 2 NICs (one for processing external web traffic, and one for communicating internally). I have installed NLB on both machines, and have created a cluster on Host A and added itself to it. However, when I try and add Host B (using the address from the external NIC) I get the following error : "The RPC server is unavailable on the specified computer". On Host B I can see that the RPC service is running fine. I can also ping and RDP from Host A to Host B with no problems either. I have disabled the windows firewall on both machines but that had no effect

• Apache log file problem

  I've recently set up an Apache 2 web server and I noticed a quite a few lines in the error and access log that start with the follow sequence (but longer). Does anyone know where this comes from? ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ ....... My set up is an Apache 2 load balancer with mod_balancer enabled and two Apache 2 web servers. All three servers write to the same log files on a share located on a NFS. My first guess is that my problem has to do with it since it's the only difference that comes to mind from other set ups I've used in the past but I'm not sure.

• Apache 2.4 and PHP 5.4 getting connection reset errors in the browser

  - by zuallauz

  In the weekend I upgraded my development web server to Apache 2.4 and PHP 5.4. In my web application which was previously working great on Apache 2.2 and PHP 5.3 it now starts getting these messages saying the "connection was reset" in Firefox. See screenshot. I am connecting to the linux machine via local LAN. I'm assuming it might be something to do with the new version of Apache or PHP, or the new LAMP stack which I downloaded from BitNami? It would seem to happen every 5-10 requests and throw this error, perhaps more likely to trigger it is if I send a POST request from a page. Is it timing out the script or something? These are just basic dynamic pages I'm loading and they worked perfectly in Apache 2.2 and PHP5.3. Here are my httpd.conf and PHP.ini if that has any clues. Any ideas? Any help much appreciated.

• Why does ganglia think my host is down?

  - by NZKoz

  I have ganglia set up to monitor our staging server, it's working great but I'm confused by the definition of 'down' to ganglia. There's a single node, running gmetad, gmond and the web frontend, but some small percentage of the time the web frontend shows some confusing output. Despite the fact that it's a single server in the cluster, and that server is the one serving the web interface, the dashboard output insists that the host is down. Then below that it has a graph which shows 50% down, 50% up. You can see an example of this here: http://i.imgur.com/MCWaS.jpg There's obviously something confusing ganglia somewhere, but I'm not sure where to start looking. Unfortunately googling for any combination of 'ganglia' 'down' 'metric name' seems return nothing but other people's ganglia installations displaying the same nonsense. Any tips on where to start looking would be greatly appreciated

• Enabling NAT loopback on HG556a router?

  - by galdikas

  This is one of the standard issue vodafone routers. So i set up web-server on my laptop, and it is accessible to the internet now. However I need to be able to access it from my machine using the public address. But I just cannot find where to enable nat loopback. I looked for options in both regular and advanced user logins (web interfaces). So I suppose the last option is telneting into it, and using commands to do it.. but I don't know how to access it (cant find the credentials). http://rhiggins.sdf-eu.org/blog/index.php?entry=entry110722-164625 In above link it says that i can find this info in configuration file, but anyone could tell me how to access it? And then what commands should I use to enable the NAT loopback?

• Hyper-V Ubuntu 10.04, Filesystem suddenly becomes Read-Only?

  - by Daniel Upton

  We are running a Ubuntu 10.04 VM on a Hyper-V system, The VM is dedicated to running one of our web applications. We have enabled the Hyper-V drivers in /etc/initramfs-tools/modules like so: hv_vmbus hv_storvsc hv_blkvsc hv_netvsc And updated the kernel image like so: $ update-initramfs -u And all was good... until.. This morning i got a support request that our web application was throwing an error 500, so i checked the logs and nothing was there. Then I remembered that I had seen this on another of our ubuntu servers so I... $ touch foo.txt And my suspicions were confirmed: touch: cannot touch `foo.txt': Read-only file system Why is the filesystem randomly becoming readonly? Is this only in Ubuntu on HV? Is it a problem on RedHat or Cent?

• UFW: force traffic thru OpenVPN tunnel / do not leak any traffic

  - by hotzen

  I have VPN access using OpenVPN and try to create a safe machine that does not leak traffic over non-VPN interfaces. Using the firewall UFW I try to achieve the following: Allow Access from LAN to the machine's web-interface Otherwise only allow Traffic on tun0 (OpenVPN-Tunnel interface when established) Reject (or forward?) any traffic over other interfaces Currently I am using the following rules (sudo ufw status): To Action From -- ------ ---- 192.168.42.11 9999/tcp ALLOW Anywhere # allow web-interface Anywhere on tun0 ALLOW Anywhere # out only thru tun0 Anywhere ALLOW OUT Anywhere on tun0 # in only thru tun0 My problem is that the machine is initially not able to establish the OpenVPN-connection since only tun0 is allowed, which is not yet established (chicken-egg-problem) How do I allow creating the OpenVPN connection and from this point onward force every single packet to go thru the VPN-tunnel?

• Best Configuration for Performance - ffmpeg streaming / mp4 /flv

  - by Sam Alex

  I have some mpeg video files and a web page. A visitor comes to that web page and according to the selected options, a php script calls ffmpeg and combines the different mpeg files and then converts it to a mp4 file. That mp4 file is then shown to the visitor using flowplayer. The MP4 creation takes some time and flowplayer takes some time to load the file. What do you think is the best way to accomplish this task ? Should i go for streaming server ? I need to reduce the time taken for conversion. Will converting to FLV be faster ?

• Vista laptop won't connect to airport extreme

  - by Hutch

  Our previous router died, and to replace it I procured an apple airport extreme. My mac, my wrt54gs (with ddwrt acting as a bridge) and a linux machine have had no problem connecting to the wireless. None of the wired clients are having a problem obviously. The problem is one of my roommates can not connect. That's not strictly true. He can connect to the network, and will, infact, get a dhcp lease. However he cannot get any packets out. Can't ping the router, can't access any web sites, nothing. However he's fine if we switch to an unsecured network. Which is obviously not acceptable. The airport only allows for 'wpa/wpa2 personal' and 'wpa2 personal' (and of course the enterprise versions there of) I keep reading about this problem in multiple spots on the web, but never see any actual answers... Anyway the laptop: hp/compaq cq50-215nr vista home premium wireess card: atheros 5007 airport is simultaneos dualband II

• Hacking prevention, forensics, auditing and counter measures.

  - by tmow

  Recently (but it is also a recurrent question) we saw 3 interesting threads about hacking and security: My server's been hacked EMERGENCY. Finding how a hacked server was hacked File permissions question The last one isn't directly related, but it highlights how easy it is to mess up with a web server administration. As there are several things, that can be done, before something bad happens, I'd like to have your suggestions in terms of good practices to limit backside effects of an attack and how to react in the sad case will happen. It's not just a matter of securing the server and the code but also of auditing, logging and counter measures. Do you have any good practices list or do you prefer to rely on software or on experts that continuously analyze your web server(s) (or nothing at all)? If yes, can you share your list and your ideas/opinions?
