• Proper way to measure the scalability of web Application

  - by Jorge

  Let's say that I have a web Application where i'm going to have 300 users and each one have to see data on real time, imagine that each client make an ajax call to the server to see in real time what's happens with the changes of the data, this calls are made each 300 ms per user. I know that i can run a simulation to see if the hardware of my server supports this example. But what happen's if the number of users start to grow up. Is there a way that i can measure the hardware needed to handle this growing behavior, a software, a formula, algorithm or maybe recommend me if i need to implement an distributed application with multiplies servers and balance the loads.

• How can I remove packages using preseed?

  - by Jorge Castro

  I'm setting up an automated "no questions asked" preseed system and using Dustin Kirkland's server preseed as an example. He uses the following line to install three packages as part of the automated install: d-i pkgsel/include string byobu vim openssh-server I am looking for the inverse of this, basically be able to remove packages as part of the automated install. I've checked the Installation Guide I've checked this example preseed, but it's not clear if this is the canonical list of every single option available. I am thinking I need to to use d-i preseed/late_command string apt-remove packagename to clean up stuff I don't want when the install is done, but I am not sure

• Looking for a customizable "Did you know..." dialog application

  - by Jorge Suárez de Lis

  I want to deploy a "Did you know..." or "Tip of the day" application at the office. It should: Show a dialog at login time with a random tip. Obviously, provide some way to store my own tips. Be easy to disable and reenable by the user itself. I'm using puppet, so I'm covered with the deployment. The tips don't even need to be gathered from a server, since I can deploy the newest tips file/database with no costs. Sure, I could hack a quick solution by using zenity and bash, but I'd like to know if there's any application out there specifically targeted at this. I don't like the zenity approach very much because it's very limited on the contents that can be displayed. No text alongside screenshots, for example. Zenity is aimed towards displaying simple dialogs.

• How can I manage multiple administrators with juju?

  - by Jorge Castro

  I manage some deployments with juju. However I am not an island, I have coworkers who also want to manage shared environments. I know I can use the following stanza in ~/.juju/environments.yaml to give people access to my juju environment: authorized-keys: [and then put their ssh IDs in here] What other best practices are available to manage multiple environments with multiple system administrators?

• can't connect to t

  - by Jorge Jimenez

  I installed, today 10/05/12, for the first time. I've used Windows for several years. Well, it's not as user friendly as some people claim. I decided to give it a try but it's very upsetting that everything seems to be OK with my wireless connection, I'm connected, and I just can not connect to the internet. When I open Firefox I get the message "Server not found". Help please! I never had this problems with Windows.

• What kind of permission is this? (Groups+Roles)

  - by Jorge

  I'm starting to need an access control for roles in my app. I don't know much of this, but I understand how vBulletin works: I create groups, then give permissions to groups. I think that what I need is the Role Bases Access Control (RBAC) , but i'm not sure, because I need groups to give permissions instead of single users (Maybe it's not that complicated to achieve). Example of what I'm thinking: Given a post: Editor's Group has permission to view it before it's published. Editor's Group has permission to edit its content. Public Group (Default) has not permission to view it before it's published. Admin Group has permission to delete the post. So basically I wan't orientation about if RBAC is what I need. And also, how would it be good to store group membership in a user, for example, would be good to have: ID NAME PASSWORD GROUPS (1, MyName, MyPassword, 1/2/3/4/5) and explode it via PHP or one registry for every Group membership in a table named permissions, example: USERID, USERGROUP values (1, 1), (1, 2) Maybe should be the second way because of the formal norms but I didn't study yet Databases 1 at college.

• ATI ES1000 graphic card

  - by Jorge Biurrun

  I am installing Ubuntu 12.04 on an IBM x3250 M2 server, It has an ATI ES1000 with no acceleration (that does not bother me, we don't need it), we use it to connect remotely via FreeNX. FreeNX works fine, (except than in Windows 7 machines NX Client shows only icons and no text ?!) but the only resolution I can get in the monitor directly attached to the server is 800x600. The display manager also shows me two monitors!, the real one and one IBM 15". Which driver should I install?. It seems that the ATI driver that comes with Ubuntu does not work properly. Any help will be apreciated. Thanks in advance. j&b

• Ubuntu 12.10 hasa no wireless connectivity on Dell Inspiron 1520

  - by Jorge Tijerina

  I have just installed Ubuntu for the first time ever. I have just installed it in a Dell Inspiron 1520 that came pre installed with Windows Vista and i currently run both of the OS (I just choose when the computer starts up). The wifi definitely works on the computer since i used it to download Ubuntu in the first place when I was using Vista. The Network Manager says that I only have a 'Wired' Network and it doesn't have any other options to choose from. I connected the Laptop into a wired connection and downloaded the 'Wicd Network Manager' but it had no effect either. From there I continued to go into 'Software Sources' and installed the wireless drive but that had no effect either. So... What can I do?

• Is code clearness killing application performance?

  - by Jorge Córdoba

  As today's code is getting more complex by the minute, code needs to be designed to be maintainable - meaning easy to read, and easy to understand. That being said, I can't help but remember the programs that ran a couple of years ago such as Winamp or some games in which you needed a high performance program because your 486 100 Mhz wouldn't play mp3s with that beautiful mp3 player which consumed all of your CPU cycles. Now I run Media Player (or whatever), start playing an mp3 and it eats up a 25-30% of one of my four cores. Come on!! If a 486 can do it, how can the playback take up so much processor to do the same? I'm a developer myself, and I always used to advise: keep your code simple, don't prematurely optimize for performance. It seems that we've gone from "trying to get it to use the least amount of CPU as possible" to "if it doesn't take too much CPU is all right". So, do you think we are killing performance by ignoring optimizations?

• Handling exceptions, is this a good way?

  - by Jorge Córdoba

  We're struggling with a policy to correctly handle exceptions in our application. Here's our goals for it (summarized): Handle only specific exceptions. Handle only exceptions that you can correct Log only once. We've come out with a solution that involves a generic Application Specific Exception and works like this in a piece of code: try { // Do whatever } catch(ArgumentNullException ane) { // Handle, optinally log and continue } catch(AppSpecificException) { // Rethrow, don't log, don't do anything else throw; } catch(Exception e) { // Log, encapsulate (so that it won't be logged again) and throw Logger.Log("Really bad thing", e.Message, e); throw new AppSpecificException(e) } All exception is logged and then turned to an AppSpecificException so that it won't be logged again. Eventually it will reach the last resort event handler that will deal with it if it has to. I don't have so much experience with exception handling patterns... Is this a good way to solve our goals? Has it any major drawbacks or big red warnings?

• Memory is leaked only in some machines.

  - by Jorge Córdoba

  We've got a situation where our application is leaking memory while doing some periodic action. The test scenario is composed of a series of processes across two relatively complex WPF windows. The weird thing about the situation is that memory only gets leaked on SOME machines, while others, having exactly the same hardware, can be working for really long times (repeating the process every minute) having their memory almost unchanged (once the GC gets rid of used memory, etc). This is .NET + WPF. Any ideas about where to start looking? What can cause leaks in only some machines? (we're talking about a 30 machine test scenario). I have few experience with WPF, could the graphic card had anything to do with it?

• Subversion and Quickbooks Files

  - by Jorge Fernandez

  I currently have a large problem on one of the file servers I manage for an Accounting Firm. Quickbooks has a tendency to create multiple files of the same thing over and over to prevent data loss. This is a good thing when you handle just a few files. But at an accounting firm it becomes a problem. Some of the older clients have 5-10 files in their respective folders, each with a different cut off date. Because of user error some of these file aren't labeled properly with their correct cutoff dates. This is where Subversion came to mind. Using the revision system would allow for 1 file to be master and have all of its revisions. Has anyone ever tried this with Quickbooks files? I've only used SVN with code for applications making each file size much smaller. How does SVN stand up with larger files like 10-25MB? I'm not exactly sure how SVN handles revisions - does it keep a duplicate of the files and duplicates the disk space space needed?

• Apache gives empty reply

  It happens randomly, and only on moodle installations. Apache don't add a line in the logs when this happens, and I don't know where to look. koke@escher:~/Code/eboxhq/moodle[master]$ curl -I http://training.ebox-technologies.com/login/signup.php?course=WNA001 curl: (52) Empty reply from server koke@escher:~/Code/eboxhq/moodle[master]$ curl -I http://training.ebox-technologies.com/login/signup.php?course=WNA001 HTTP/1.1 200 OK The apache conf is quite straightforward and works perfectly in the other vhosts <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /srv/apache/training.ebox-technologies.com/htdocs ServerName training.eboxhq.com ErrorLog /var/log/apache2/training.ebox-technologies.com-error.log CustomLog /var/log/apache2/training.ebox-technologies.com-access.log combined <FilesMatch "\.(ico|gif|jpe?g|png|js|css)$"> ExpiresActive On ExpiresDefault "access plus 1 week" Header add Cache-Control public </FilesMatch> </VirtualHost> Using apache 2.2.9 php 5.2.6 and moodle 1.9.5+ (Build: 20090722) Any ideas welcome :)

• Is there a way to capture the "network user name" and the "host name" during a "login failed" alert

  - by Jorge Rivera

  I am a SQL Server 7 DBA and I would like to "improve" the default "Login failed" alert that brings SQL 7. I need a way to know what "user" (network user name) was trying to connect to the server (not only the SQL user account) and I would like to know from where the user was trying to connect (the hostname). Does someone know if this is possible? Using the SQL Profiler is not the best way since is a resource consuming task. Would be a way to setup an alert for doing this? Thanks in advance.

• Cloudstack virtual machines can't communicate with virtual routers when they are on different hosts

  - by Jorge Suárez de Lis

  I'm using Cloudstack 2.2.14 on a Ubuntu 10.04 set of hosts, and I have a problem on my setup. I have two hosts running. When a virtual router is created on host 1 and a virtual machine using that virtual router is created on host 2, or vice versa, I have no connectivity at all on the virtual machine. First of all, I have to setup the network manually on that virtual machine -usually DHCP is working, but not here-. Then, I can't ping to the virtual router from the virtual machine or vice versa. When both virtual router and virtual machine are created on the same host, everything works! Maybe those packages are being filtered somehow? I have no clue on how to proceed. Both hosts can communicate directly outside the virtualization.

• NFSv3 + ACL: mask is gone on clients

  - by Jorge Suárez de Lis

  I'm sharing a NFS folder among a user group. The default umask on the clients is 0700, and this is a problem because newly created files won't be readable/writable by another users. So, I'm using ACLs to force the umask 0770 on the shared folder, and this works OK on the server, but not on the clients. server # getfacl /export/proyectos getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:mask::rwx default:other::r-x server # getfacl /export/proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx mask::rwx other::--- default:user::rwx default:group::rwx default:mask::rwx default:other::--- As you see, the default (and also a specific on the second directory) mask ACLs are being applied. I mount the whole share on the client: 172.16.54.56:/export/proyectos on /proyectos type nfs (rw,noatime,rsize=131072,wsize=131072,acregmin=10,acl,nfsvers=3,addr=172.16.54.56) But the mask and default:mask ACLs are gone. client $ getfacl /proyectos/ getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/ # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:other::r-x client $ getfacl /proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx other::--- default:user::rwx default:group::rwx default:other::--- It lacks the default:mask and mask ACLs, the only ones that I've setted. So the proposed solution to enforce umask won't work for me. Why is happening this?

• Filesystem access through web interface

  - by Jorge Suárez de Lis

  I have an SSH+Samba server so people can access its files from anywhere on the network. I thought it would be also interesting to provide access through a web interface, so they can access the files even when they don't have access to the VPN or a Samba/SSH client. Something like the Ubuntu One or Dropbox web interface. The http server could be on the same machine as the SSH+Samba, so it should just provide access to local files and some way to login with their username/password. Someone knows any software like this?

• My linux server "Number of processes created" and "Context switches" are growing incredibly fast

  - by Jorge Fuentes González

  I have a strange behaviour in my server :-/. Is a OpenVZ VPS (I think is OpenVZ, because /proc/user_beancounters exists and df -h returns /dev/simfs drive. Also ifconfig returns venet0). When I do cat /proc/stat, I can see how each second about 50-100 processes are created and happens about 800k-1200k context switches! All that info is with the server completely idle, no traffic nor programs running. Top shows 0 load average and 100% idle CPU. I've closed all non-needed services (httpd, mysqld, sendmail, nagios, named...) and the problem still happens. I do ps -ALf each second too and I don't see any changes, only a new ps process is created each time and the PID is just the same as before + 1, so new processes are not created, so I thought that process growing in cat /proc/stat must be threads (Yes, seems that processes in /proc/stat counts threads creation too as this states: http://webcache.googleusercontent.com/search?q=cache:8NLgzKEzHQQJ:www.linuxhowtos.org/System/procstat.htm&hl=es&tbo=d&gl=es&strip=1). I've changed to /proc dir and done cat [PID]\status with all PIDs listed with ls (Including kernel ones) and in any process voluntary_ctxt_switches nor nonvoluntary_ctxt_switches are growing at the same speed as cat /proc/stat does (just a few tens/second), Threads keeps the same also. I've done strace -p PID to all process too so I can see if any process is crating threads or something but the only process that has a bit of movement is ssh and that movement is read/write operations because of the data is sending to my terminal. After that, I've done vmstat -s and saw that forks is growing at the same speed processes in /proc/stat does. As http://linux.die.net/man/2/fork says, each fork() creates a new PID but my server PID is not growing! The last thing I can think of is that all process data that proc/stat and vmstat -s show is shared with all the other VPS stored in the same machine, but I don't know if that is correct... If someone can throw some light on this I would be really grateful.

• What kind of SATA interface is on a Thinkpad X120E?

  - by Jorge Castro

  I recently ordered a Thinkpad X120E with an AMD Fusion (Zacate) chipset. I am eyeballing an SSD for it, however newer SSDs are coming out with 6Gbps SATA interfaces. I doubt such a cheap laptop has 6Gbps SATA, but I'm debating waiting the a bit longer until the Intel 510 series come out, if anything to future proof myself by putting it in this laptop and then later on when I do upgrade to a laptop with 6Gbps SATA I'll be good to go. The hardware manual mentions that the motherboard is for a "AMD Fusion E-350" but the specifications of each hardware part isn't part of the manual. Does anyone have any information on the kind of SATA controllers in Fusion laptops so I can make a better purchasing decision?

• Good set of web hosting permissions?

  - by Jorge Israel Peña

  Hey guys, I just got a linode and I'm in the process of configuring it. It's running nginx with php-fpm and passenger. nginx was compiled and is running as user nginx. php-fpm (php with fastcgi process manager) is running as www-data (in group www-data). My sites are currently in /var/www, so for example /var/www/test.com I'm just wondering what the general 'flow' of things is. So for example, /var/www is owned by root, should I chown of /var/www/test.com to nginx or www-data? Or should I put nginx in the www-data group? How should site uploading work, I just transfer files to the /var/www/test.com directory as root (sudo) and then chown -R www-data:www-data .? Thanks. I'm capable of figuring things out on my own, I'm just wondering what the typical/general way of handling users/groups/permissions/site-files is on linux with a webserver.

• Provisioning SIP Phones over the internet

  - by Jorge Fernandez

  I have a few SIP Phones that are located of site and connect to my PBX over the internet to make calls. For some reason one of these phones has become unprovisioned. In my office phones get provisioned by the server via TFTP. The ones that I have off site I pre-provisioned manually before I sent them off-site (I'm in Florida the phone is in New Jersey). Whats the best way to provision these over the internet? TFTP is very insecure. Sending the plain text profiles with the SIP Account and Password over the internet is out of the question. The phones have been off-site for about 6 months without any issues. Im using Trixbox and Cisco 7940 Phones.
