• DNS and RPC Unavailable

  - by Berek Bryan

  I have a server that is host a MSSQL database and some other server related tasks. The server communicaties with a large number of devices. The devices send data to the server. The communication links are down between the devices on the intranet and to the outside world. However it seems I can ping and can be pinged from machines on the same switch. This includes the DNS Servers. When I run, C:\ipconfig /registerdns I get RPC Server is Unavailable. So, it seems that the server can not verify the DNS server. Both DNS server are up and running. No other machines are affected on the network.

• Can someone explain the fascination with twitter.com? [closed]

  - by raven

  I don't get it. WTF do people see in this? I'm trying to figure it out, but I can't. Have you seen what people post? Let's use Jeff Atwood as an example. What does he gain by posting (with disturbing frequency) all those, well... posts (I find the term "tweets" disgusting). What is a "follower" supposed to get from these posts? I know many of you are thinking, "Just don't use it!". Yes, I know I don't have to use it, but it's like asking me not to look at the space shuttle that just crashed in my front yard. The rest of the world thinks it's the greatest thing since sliced bread. I'm just trying to understand what people see in it.

• Prevent Internet Explorer 8 from exiting when closing the last tab

  - by LongTTH

  Firefox doesn't exit when I close the last tab, just by doing some customization in about:config. But now, my company has to work with some website that only works well on Internet Explorer. I currently use Internet Explorer 8 on Windows XP SP3. So, how do I prevent Internet Explorer 8 from exiting when closing the last tab? I've searched for such a feature for a while but found nothing helpful. FYI I gave up with my "customization habit", now I'm trying to live with IE world, ... phew...

• 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.

• What's the weirdest thing you've ever seen a non-techie do to a computing device?

  - by googletorp

  I thought it would be fun to bring out the stories on what people have done throughout the ages with computers due to their sometimes, to put it politely, less than perfect grasp of technology. I'll start out with a little story from my high-school days. After graduation, a classmate of mine, who took IT and subsequently scored an A in the subject, was sent an e-mail by a friend. She replied to his mail: "I'm sorry, but I can't reply your mail, since I don't have your email address." Till this day I still can't understand why she gave such a weird reply as she was a bright girl although not a techie. Now, let's hear those other battle stories from the real world...

• Web application and remote storage of files

  - by Matt

  Hi have a web application that can store lots and lots of files on the server. i.e. users upload data to it. The files are stored below a particular storage path. The web host will be an IBM xseries 345. However, the disks are really expensive so we would like to put the files onto a less expensive server. Now here is the question. Should I use an NFS mount on the IBM server of a path on the storage server? Or should I write some scripts to upload the files to the storage server instead. Both the storage server and the web host are on the same network. Only the web server is visible to the world. Is NFS performance suitable for an expected low to moderately loaded server?

• Information System for an Academic Institution

  - by birukw

  Hi, The University I am working for is undergoing a major renovation of the ICT system. The team currently undertaking the task is designing a centralized system with the intent of providing most (if not all) services of the institution electronically. Most of us are academicians with little practical experience. The questions we need answers for are What are the systems (preferably free, as in Beer, and/or open) and best-practices in use in other academic institutions? What are the experiences of people administering academic ICT systems? What are the overheads of attempting to provide services through an intranet cloud (like UEC) for us (a medium-sized academic institution, in a third-world country)? We would very much appreciate it if you could give us your take on the situtation. Thanks

• Best practice Raid groups for EqualLogic PS6510X

  - by 20th Century Boy

  We are thinking about purchasing 4 x EqualLogic PS6510X SANs (the Sumo boxes). Each has 48 x 600GB 10k SAS drives. They will be stacked to form a logical pool of storage (all in the same location). I understand that when you create a RAID group its done on a "per box" basis. So one box could be Raid 50, another Raid 10 etc. My question is, should I make one box a "performance" box ie Raid 10, and the other boxes "standard" ie Raid50? How do people configure their EQL arrays in the real world?

• Linking to lua libraries w/ codeblocks on linux

  - by person

  After I downloaded the source for lua, I followed the install instructions, doing... make linux install make generic install I've also done the make test and it passes, printing out Hello World, from Lua 5.1. However, I can't link to the lua libraries in CodeBlocks. I know where lualib.a is (usr/local/lib) which I set in my Search Directories for the linker. I still get error messages like... undefined reference to lua_isstring Am I missing something critical here? P.S. I had this running on Windows via Visual Studio.

• Best and Proper Permissions Settings for Directory

  - by Dr. DOT

  I am interested in knowing the proper, yet security-conscious settings for a directory. Here's my scenario: I have a username for FTP access to my server called "user". For the purpose of the scenario, PHP runs as "nobody" on my server. I have a directory off the document root called "sample". The "sample" directory is chmod'd at 0755 (drwxr-xr-x) "Sample" is owned by "user" and the group is set to "user" The above is all very straight forward and standard. So I want to have a script be able to create (mkdir) and delete (rmdir) directories under "sample". Yet, I don't want to obviously overly expose my server by opening up the permissions (I could easily chmod sample to 0777 and make it world write-able). What is the best combination of permissions, owner settings and/or group settings to allow my script to create and delete directories under "sample" while retaining the ability for "user" to continue to FTP into the directory? Thanks.

• Can I rely on S3 to keep my data secure?

  - by Jamie Hale

  I want to back up sensitive personal data to S3 via an rsync-style interface. I'm currently using s3cmd - a great tool - but it doesn't yet support encrypted syncs. This means that while my data is encrypted (via SSL) during transfer, it's stored on their end unencrypted. I want to know if this is a big deal. The S3 FAQ says "Amazon S3 uses proven cryptographic methods to authenticate users... If you would like extra security, there is no restriction on encrypting your data before storing it in Amazon S3." Why would I like extra security? Is there some way my buckets could be opened to prying eyes without my knowing? Or are they just trying to save you when you accidentally change your ACLs and make your buckets world-readable?

• Reconnoiter - Anyone using it?

  - by Marco Ramos

  Reconnoiter is a new tool in the world of monitoring. It is not only a trending tool but also alerting/fault detection one. In my particular case, I reckon that it's in the trending capacities that Reconnoiter has a very huge potential. One of the premises Recoinnoter is built upon is that RRDTool large installations are very inneficient regarding I/O and I think this is RRDTool major problem. One of the things that would make me change from Cacti is, obviously, the cost of change and the learning curve. So, any of you has experience with Reconnoiter? How's the learning curve? Was it difficult to move from RRDTool frontend applications (Cacti, Munin, Ganglia) to Reconnoiter? I'm looking forward to read your opinions.

• Why is my Wifi connection slower than ethernet even though bandwidth should saturated?

  - by supercheetah

  I'm wondering why it is that my wireless connection is slower than my wired connection for things going to the outside world (so, not files being transferred within the network), which is should be faster than the outside connection, which, I would think, would mean that downloading something like an ISO or other large file from the Internet should be the same either way since that should saturate the connection anyway. Does it have something to do with the encryption (WPA)? Could it have something to do with MTU since the MTU for ethernet can be in the range of 1500 to 9000 bytes, and 2304 bytes for 802.11? Do wireless packets have to be buffered, whereas this wouldn't be an issue with ethernet? What's the math behind the difference?

• What is the easiest way to get MySQL's Archive Storage Engine working on CentOS 5.4

  - by tronda

  The Archive Storage Engine is not enabled by the default build of MySQL in CentOS/RHEL. I would like to enable it on our CentOS 5.4 server. My initial reaction was to modify the SPEC file for the SRPMS file, but this indicates that this might not be that easy. There's always the option to build from MySQL source, but I would prefer if possible to stay within the RPMS/Yum world. Does anybody have a successful approach to this by using RPMS/SRPMS/Yum? Some patches which makes this work flawless with SRPMS?

• multiple file systems for mysql

  - by RainDoctor

  Does mysql support multiple file systems for a single database with most of the tables being on MyISAM? Context: we have a 1.5TB mysql database, which is increasing at the rate of 200GB per month. The storage is directly attached, whose slots are almost full. I can add another DAS, and increase the file system. But resizing volume, resizing file system, etc are getting messy. Is there a concept of "tablespace, datafile" (like in oracle) in MySql world? Or how you guys manage mysql db with these kind of constraints?

• Dummy HTTP server for debugging

  - by Andrea

  This is more or less the inverse of my previous question. I need to debug some HTTP requests that I am making. Since these requests arise from the use of some external libraries, sometimes I am not sure of what is the actual data I am sending. Is there some dummy server (for Linux) that accepts HTTP requests and just prints them somewhere so that I can inspect them? I would like to be able to see in plain text the full request, like POST /foo HTTP/1.1 Host: www.example.com Accept: text/xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-gb,en;q=0.5 Content-Type: text/plain Content-Length: 11 Hello world

• Known Hosts ECDSA Host Key Multiple Domains on One IP

  - by Jonah

  Hello, world!, I have a VPS set up with multiple domain names pointing to it. Arbitrarily, I like to access it via SSH through the domain name I'm dealing with. So for example, if I'm doing something with example1.com, I'll log in with ssh [email protected], and if I'm working with example2.com, I'll log in with ssh [email protected]. They both point to the same user on the same machine. However, because SSH keeps track of the server's fingerprint, it tells me that there is an offending host key, and makes me confirm access. $ ssh [email protected] Warning: the ECDSA host key for 'example2.com' differs from the key for the IP address '123.123.123.123' Offending key for IP in /home/me/.ssh/known_hosts:33 Matching host key in /home/me/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? Is there a way to ignore this warning? Thanks!

• Downloading movies with Bit torrent

  - by Quintin Par

  I come from a part of the world where the average Hollywood movie is released a year + later than in US. For example: Transformers: Revenge of the Fallen will be released only 5-6 months down the lane. The Reader, I think will not be released at all. Is this a right justification for me to download movies from the torrent networks and watch them? Even if I don’t share it? P.S I don’t think my country has all these American type cyber laws to catch me. It’s just the guilt feeling. Note: SuperUser is not a legal resource.

• Amazon EC2, fastest way to get a node into an existing cluster

  - by imaginative

  I'm new to Amazon AWS. A lot of the time I hear about people folks spawning instances and almost instantly putting them behind a load balancer and into an existing cluster. In the traditional world of managed machines, this would include provisioning hardware, installing an OS, configuring the network on the machine and once the network is available, use a tool of your choice such as CFengine, Puppet or Chef to bootstrap the machine based on its class. It seems like there are "shortcuts" that are able to get a server of a particular class up and running in Amazon EC2. If I have a particular stack running on my server, such as erlang, tomcat6 etc.. what's the fastest way to get these up and running and hooked into Amazon's load balancer? From network, to software stack to kernel tuning? Is it a combination of creating an AMI then running a tool like Puppet against the new instance? Any idea

• Memory upgrade - is the site reliable?

  - by Yuval

  Hi, I have a late-2008 unibody macbook model with 2 GB of ram. I am looking to upgrade to 4 GB of ram. I looked about a month ago at Other World Computing's 4 GB upgrade kit and I remember it being around $80. I looked today, finally getting to buy it and it went up to almost $100. I found another site, memoryupgrade.pro that calls itself "Pro memory upgrade" and it looks legitimate - it sells the memory for around $80 in its own brand. The only thing is, I haven't been able to find any reviews about it, and I'm not sure if it actually is reliable. Does anybody have any experience with this site? Does anybody have any other suggestions for buying macbook memory? I have friends who bought from OWC and were happy, should I just spend the extra $30 (including shipping) and buy from them? Thanks!

• Why does Tomcat try to use the cache when compilation failed?

  - by etheros

  For some reason, it appears Tomcat is trying to hit its compilation cache when compilation failed. For example, if I create a JSP containing nothing but Hello, <%=world%>!, predictably, I get an error: org.apache.jasper.JasperException: Unable to compile class for JSP. Subsequent requests however alternate between this and org.apache.jasper.JasperException: org.apache.jasper.JasperException: Unable to load class for JSP. Further, if I create a JSP containing Hello!, it of course works just fine. If I modify it contain Hello, <%=name%>!, the response alternates between the previously-mentioned compilation error, and the cached Hello!. What's going on?

• How GZipped contents are transfered on the web?

  - by PJ

  I heard that static contents like CSS and JavaScript can be better delivered in GZip format. And Content Developer Network (CDN) always does so. However I don't understand how the format works. First when I tried making a gzipped file via command-line. The file extension is .gz. This is different from .css and .js. How do browsers recognize which file is gzipped or not. Second, how browsers "decompress" files? I dragged my index.html.gz onto my browsers. But no one worked. How do such gzipped work in the real world? What do I need to do if I want to serve CSS/JavaScript using Gzipped format.

• What are the mandatory Linux kernel modules to run inside of ESXi

  - by Marcin

  I'm used to rolling my own kernels for servers, as it nicely minimizes the number of exploits (and the resulting patches) to take care of. In a traditional (bare metal) world, the whole process is about knowing what you have (hardware), and what you need (Ethernet, IPv4, iptables, etc.) In a virtualized environment, some things stay the same (still need Ethernet and IPv4), some things go away (power management), and then there are some new needs (vxnet3, or vmware-tools, even though that's compiled outside of the kernel). So my question mostly concerns itself with the last two categories: what can I remove completely, and what new stuff do I want? For example, what IO scheduler do I want, if all my disk operations are going through another filesystem/scheduler/cache to get to the virtual disk? Do I need hyper-threading enabled, or is the VM going to show them to me anyway as a CPU anyway? Do I need Large Receive Offload turned on, or is that something that the hypervisor's network drivers are going to do for me?

• organizing images by resolution with batch files

  - by Anthony

  Doing some digging I'm trying to figure out a command line solution for organizing very large archives of images based on their resolution into folders, 1920x1080, 1600x1200, 1600x900, etc. I've come across a few post on Superuser mentioning something called ImageMagick, is that the best method to the madness I'm trying to accomplish? I've never used any command line functions/applets/tools other then those that come from Microsoft. I'm rather new to command line usage but ive been enjoying the hell out of it using Powershell, xcopy and robocopy. I am slowly trying to push myself further into the Linux world with Ubuntu running on one of my physical machines as well as a virtual machine so that's an option as well.

• Should I Upgrade My Old Wireless Router?

  - by lyngbym

  I have an old wireless router, and I mean stone age old (5 years). There is nothing wrong technically with the router, it serves my wireless needs at home but it is really darn old. A search on Belkin's site for F5D7230-4 actually turns up a different old model so I scrounged up this old review for you to get a sense of what I'm running: http://www.pcmag.com/article2/0,2817,1572451,00.asp. Is there a valid security reason to replace this router in 2009? Google searches have turned up a few security threats to it and Belkin hasn't released new firmeware in years for it. I am starting to think I should replace it mainly because its NAT is about the only thing protecting me from the outside world. Buying a new wireless router is a boring way to spend money since it just sits on a shelf doing its job. Thoughts?
