• A font like RomanS in appearance but with support for more characters (Autocad)?

  - by kokbira

  In a Autocad 2010 installation, the standard font used is RomanS. That font is so limited on characters, so when I use "text" command I cannot add "³" on text of cubic meters measures (a "?" is displayed instead of the "³" character - see isolated text on figure below and Font characters Latin Supplement range). When I use a dimension command, like multileader, Autocad "corrects" that issue using another font that support that missing character, resulting on an awful mixture (see text on multileader below - on multileader text properties, we can see 3m{\fArial|b0|i0|c0|p34;³}). I can easily change that font with another, like Verdana, Times New Roman... that have more characters than RomanS font, but I would like to use an alternative font more like RomanS in appearance. Any help?

• Connecting FreeNAS 8 to Mac OS X Lion LDAP Server

  - by Absolution

  I currently have Mac OS X Lion Server running from a MacMini and want to use it purely as an LDAP server for authentication for FreeNAS 8. I have FreeNAS setup and running on a VM, all features working correctly and as expected however I cannot connect to my LDAP server (MacMini). Error message; **Nss_ldap: could not search LDAP server – server is unavailable** For LDAP service settings in FreeNAS, I know my Hostname and Base DN are correct (exact copies of what I set originally and ones that are shown in server:open directory overview) however I am unsure what to enter for Root bind DN, password and Suffix’s. I have researched into where I can find these out and other than following the FreeNAS examples it appears there is a way to find out within the Server Workgroup Manager specific to my settings – however this function is unavailable to me and cannot be ‘ticked’ to view for some strange reason. Some forums explain how Root bind DN should be uid=admin, dc=… and others cn=admin, dc=… – I’m rather confused and would appreciate your help or advice with this.

• Shell script with ImageMagick: hangs forever?

  - by AP257

  I've generated a shell script that uses ImageMagick to convert and crop around 18000 images. Here's a sample entry (so there are 18000 of these): if [ ! -f ./cropped/16333-1.png ] then convert -crop 724x118+876+1989 ./lin/34.png ./cropped/16333-1.png echo cropping 16333-1 fi if [ ! -f ./cropped/16333-1_thumb.png ] then convert -define jpeg:size=400x100 ./cropped/16333-1.png -thumbnail '400x100>' -background transparent -gravity center -extent 400x100 ./cropped/16333-1_thumb.png echo thumbing 16333-1 fi The script only runs for about 2000 images before hanging forever. Am I missing something, or leaking memory somewhere? Thanks for your help!

• 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.

• Setting up a router as a DNS server only

  - by Jacob R

  I have a Linksys WRT54GL router that I don't need anymore, since I had to buy a 3G capable router (Dovado 3GN). As I only have a 3G connection at home, I want to optimize it as much as possible. I want to setup a caching DNS server, including some blacklisting of ad domains. The router currently runs the DD-WRT firmware. Is it possible to use this router as an ordinary computer, running only a DNS server, disabling all other features such as DHCP, WLAN, etc? Connecting it to my other router, should I simply run a cable into the WAN-port of the Linksys router?

• Color Temperature in PowerPoint 2010

  - by Otaku

  I'm teaching PowerPoint 2010 and it's got some great new features. Unfortunately, one that I can't wrap my head around is the the new "Color Temperature" feature for pictures. I do understand color temperature in general (i.e. the lower the number, the "colder"/"oranger" - the higher the number, the "hotter"/"bluer"). The way PowerPoint implements it seems opposite from most other programs - like Photo Filter in Photoshop. So I need to understand what this feature is in more detail so I can explain it to my students. Does anyone know?

• Content Length and Transfer Encoding Chunked nginx, node-http-proxy

  - by rampr

  I have the following setup - node-http-proxy acts as a reverse proxy forwarding all requests to nginx/socket.io as necessary My problem is this When I send a HTTP DELETE request from the browser, node-http-proxy adds a header "Transfer Encoding Chunked" as the request from the browser had no Content Length. The request from the browser had no Content Length as it had no body. Nginx doesn't like the Transfer Encoding Chunked Header and throws a 411 asking for Content-Length. The problem gets solved when I send dummy data as part of the DELETE request so there is a Content Length and node-http-proxy doesn't add Transfer Encoding Chunked header and nginx is happy. I want to understand if node-http-proxy isn't working as expected, because it adds a Transfer Encoding Chunked header when Content Length is missing because there is no Content Body.

• Always use one slow connection in preference of a "faster" one

  - by billc.cn

  In Windows, there's this automatic metric thing where the metric is selected according to the declared speed of the link. I now have a gigabit LAN routed to a 2MB DSL service and a HSDPA mobile broadband connection. The former is always chosen for Internet packets even though the latter is actually faster. I tried setting the mobile broadband's interface metric to 1 and raising its priority in the advanced settings of the adapter settings, but this does not seem to affect the metric of the default route. The default route to the Ethernet interface always have a lower metric than the mobile broadband interface. Am I missing something here?

• Cropping a PDF File's Margin During Printing

  - by JavaMan

  I'm using the free Acrobat Reader to print out some pdf documents having very large top/bottom/left/right margins. I want to remove the margins (which are wasting too much space and making the fonts too small). I used to use Acrobat (the paid version having edit features) to crop the src pdf file manually. But since it is an old version it does not support new pdf format and I don't want to upgrade for such a simple use. Is there any free way to crop/remove unwanted white margins from the printed pdf? I am thinking to print the pdf files to a PDF Printer like the Bullzip PDF Printer and enlarge the output file manually so as to remove any white margin. But there does not seem to be such a feature in Bullzip PDF Printer. Is there any other virtual printer software that can be used for this purpose?

• Good 1U Rack Firewall

  - by AX1

  Hello, I'm trying to find a good 1U rack firewall at a reasonable price. Most pricing is completely out of space (thousands of dollars? Why?). I don't want to list all features I need/want (there are too many variations but I don't care about most of them) - I'm just looking for something simple and not overly expensive. I've looked at the WatchGuard XTM 505 which is more reasonably priced -- are there any other firewalls in that range or even less expensive that are good for a small company?

• cannot connect to MS FTP 7.5 on Windows 2008 on Amazon EC2 instance

  - by minerj

  I have just installed the MS FTP 7.5 upgrade on my Windows 2008 Server (Service Pack 2) running on an Amazon EC2 instance. In the FTP Firewall Support settings for the server in IIS Manager I have set up the passive port range 45001 - 45005 and also set the External Firewall IP address to match the assigned Amazon Elastic IP address. Using the AWS Console I changed the Security Group for the server to allow access to the server through ports 21 and 45001 through 45005. Using an FTP client (either the command line FTP client or Windows Explorer) on the Amazon server I can connect to the FTP server but I cannot connect with an external FTP client. When I checked to see which ports were open on the server using Shields Up it shows that port 21 is open but ports 45001 to 45005 are closed. I assume I'm missing something. Any help greatly appreciated.

• Ubuntu 11.04 and OpenLDAP - where is the config?

  - by Tom SKelley

  I've been asked to setup a multimaster LDAP environment on Ubuntu 11.04 - instead of a single master server. I cloned the master server and recreated it into two VMs. I am trying to follow the instructions on the OpenLDAP documentation here: http://www.openldap.org/doc/admin24/replication.html and it talks about modifying the cn=config tree within LDAP. The subdirectory tree appears to be there at: /etc/ldap/slapd.d/ and a slapcat -b cn=config drops out a load of config information. When I try to connect using a browser and the admin bind credentials: ldapsearch -D '<adminDN>' -w <password> -b 'cn=config' I get: # extended LDIF # # LDAPv3 # base <> (default) with scope subtree # filter: (objectclass=*) # requesting: ALL # # search result search: 2 result: 32 No such object I don't see the config context when I connect via an LDAP browser either. I'm sure I'm missing something, but I can't see what it is!

• Can't set up IIS Web Server on Server 2008 x64 correctly (what have I missed?)

  - by balexandre

  Using a VM I installed Windows 2008 Server x64 and as the image below shows, added the IIS Role full image and assigned all role features of IIS full image But if I have an ASP.NET (aspx) page that does (C#) Session["test-session"] = "A"; and read in other page I always get nothing! NOTE: I do have an entire ASP.NET web application, the example above is to be succinct and explicit on what is the problem I'm facing. Can anyone know what do I have to do to the Server, so I can use the Session variables? All help is greatly appreciated, Thank you

• CentOS (rel6) with default python 2.6, but seperate 3.3.5 installation

  - by Silvertiger

  I have a CentOS server (rel6) that had python installed (2.6), but I needed a few features in 3.3+. I installed 3.3 into a seperate folder and made a symbolic link to execute it: I installed setup tools: yum install python-setuptools I installed a needed module"pandas" easy_install pandas I executed my pyton script, which encountered an error that required i use a newer version I downloaded and installed Python 3.3.5 to it's own folder so as to not override my default python wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz tar xJf ./Python-3.3.5.tar.xz cd ./Python-3.3.5 ./configure --prefix=/opt/python make make install Made s symbolic link to allow me to execute this new python: ln -s /opt/python3.3/bin/python3.3 ~/bin/py The problem is that when I execute the python script with my new py alias, it does not have all the addons needed (explicitly MySQLdb) which the default install does. How do i go about installing the MySQLdb module, or any for that matter, to be reachable or useable for the new Python 3.3.5 installation? Or is there a way to make the current modules in 2.6 available to 3.3.5 as well?

• Hiera + Puppet classes

  - by Amadan

  I'm trying to figure out Puppet (3.0) and how it relates to built-in Hiera. So this is what I tried, an extremely simple example (I'll make a more complex hierarchy when I manage to get the simple one working): # /etc/puppet/hiera.yaml :backends: - yaml :hierarchy: - common :yaml: :datadir: /etc/puppet/hieradata # /etc/puppet/hieradata/common.yaml test::param: value # /etc/puppet/modules/test/manifests/init.pp class test ($param) { notice($param) } # /etc/puppet/manifests/site.pp include test If I directly apply it, it's fine: $ puppet apply /etc/puppet/manifests/site.pp Scope(Class[Test]): value If I go through puppet master, it's not fine: $ puppet agent --test Could not retrieve catalog from remote server: Error 400 on SERVER: Must pass param to Class[Test] at /etc/puppet/manifests/site.pp:1 on node <nodename> What am I missing? EDIT: I just left the office but a thought struck me: I should probably restart puppet master so it can see the new hiera.conf. I'll try that on Monday; in the meantime, if anyone figures out some not-it problem, I'd appreciate it :)

• Apache ProxyPass ignore static files

  - by virtualeyes

  Having an issue with Apache front server connecting to a Jetty application server. I thought that ProxyPass ! in a location block was supposed to NOT pass on processing to the application server, but for some reason that is not happening in my case, Jetty shows a 404 on the missing statics (js, css, etc.) Here's my Apache (v 2.4, BTW) virtual host block: DocumentRoot /path/to/foo ServerName foo.com ServerAdmin [email protected] RewriteEngine On <Directory /path/to/foo> AllowOverride None Require all granted </Directory> ProxyRequests Off ProxyVia Off ProxyPreserveHost On <Proxy *> AddDefaultCharset off Order deny,allow Allow from all </Proxy> # don't pass through requests for statics (image,js,css, etc.) <Location /static/> ProxyPass ! </Location> <Location /> ProxyPass http://localhost:8081/ ProxyPassReverse http://localhost:8081/ SetEnv proxy-sendchunks 1 </Location>

• faster ( squid + apache httpd + apache tomcat )

  - by letronje

  We have a production setup where we have Squid in the front(caching images, js, css, etc) Apache httpd in the middle(prefork + mod_rewrite + mod_jk/AJP + mod_deflate + mod_php(few php pages)) Apache tomcat 5.5 at the end serving all the dynamic stuff. What would be the best way to reduce the overhead of having 3 servers in the request path ? Wondering if replacing httpd with a faster web server like nginx/lighttpd will help. httpd right now does the job of url rewriting(for clean urls) and talking to tomcat(via mod_jk) and compressing output(mod_deflate) and serving some low traffic php pages. What would be ideal replacement for httpd given that we need these features? Is there a way to replace (squid + apache) with a single entity that does caching well (like squid) for static stuff, rewrites url, compresses response and forwards dynamic stuff directly to tomcat ? heard abt varnish cache, wondering if it can help.

• IBM storage ds3400 Cant connect to management using fiber

  - by Eli B

  i have a problem with a DS3400 IBM storage system we bought a few years back. when i try to manage the storage using its IBM storage management i cant find it using automatic detection even though its connected directly using the fiber and i can see the Logical drives connected and working properly. when i tried to connect the two management Ethernet wires and manage the storage directly by entering the IP address manually i am able to connect however after i make several changes to the controller configuration one of the controllers stops responding and i am not able to ping it directly (since you cant make any changes without being connected to both controllers this is a problem) whats more bizarre is that when i change the IP of the controller that doesn't respond it starts working .. i have found some articles over the web explaining stuff about LUN31 being missing and causing similar problems however all my attempts to manually configure it failed . *link to an example http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5075711 in short im trying to get my storage to appear in the storage manager when directly connected using only the fiber cable directly attached. thanks in advance

• Why can't I create an Alias Resource Record Set for an EC2 instance

  - by praterade

  I have been working with AWS for over a year, setting up EC2 instances, domains, ELBs, etc. When I want to assign a subdomain to an EC2 instance, I have to create an elastic IP (that I pay for), then assign a CNAME record to that elastic IP. When I want to assign a subdomain to an ELB (load balancer) instance, I just create an alias resource record set to the ELB. I've read over the docs and don't understand why AWS doesn't support aliasing to instances. Am I missing a key concept here? Wouldn't it be simpler to just alias EC2 instances and skip the whole elastic IP bit?

• Apache + LDAP Auth: access to / failed, reason: require directives present and no Authoritative hand

  - by Karolis T.

  Can't solve this one, here's my .htaccess: AuthPAM_Enabled Off AuthType Basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthName "MESSAGE" Require ldap-group cn=CHANGED, cn=CHANGED AuthLDAPURL "ldap://localhost/dc=CHANGED,dc=CHANGED?uid?sub?(objectClass=posixAccount)" AuthLDAPBindDN CHANGED AuthLDAPBindPassword CHANGED AuthLDAPGroupAttribute memberUid AuthLDAPURL is correct, BindDN and BindPassword are correct also (verified with ldapvi -D ..). Apache version: Apache/2.2.9 (Debian) The error message seems cryptic to me, I have AuthzLDAPAuthoritative on so where's the problem. EDIT: LDAP modules are loaded, the problem is not with them being missing. # ls /etc/apache2/mods-enabled/*ldap* /etc/apache2/mods-enabled/authnz_ldap.load /etc/apache2/mods-enabled/ldap.load EDIT2: Solved it by changing funky Require ldap-group cn=CHANGED, cn=CHANGED line with Require valid-user Since AuthzLDAPAuthoritative is on, no other auth methods will be used and valid-user requirement will auth via LDAP.

• Configuring vsftpd with nginx on ubuntu

  - by arby

  I have vsftpd installed on Ubuntu 12.04LTS along with nginx, php, and sql on an Amazon ec2 instance. The web server is good to go, but I'm having trouble connecting to the FTP server. I'm not quite sure how to set the privileges or what configuration options I might be missing. By default, the location of the web root is at /usr/share/nginx/www and it is owned by root:root. The web server runs as user www-data in the group www-data. I've opened port 21 and set the passive ports in the ec2 backend and ufw firewall. In vsftpd.conf, I have: ... anonymous_enable=NO local_enable=YES local_umask=0027 chroot_local_user=YES pasv_enable=YES pas_max_port=12100 pasv_min_port=12000 port_enable=YES ... Now, I'm unsure how to create the FTP user that when I login, displays my web directory with write access. I've tried it a few different ways, but I keep running into errors (either no connection, no write access, or very slow timeouts.)

• decrypting AES files in an apache module?

  - by Tom H

  I have a client with a security policy compliance requirement to encrypt certain files on disk. The obvious way to do this is with Device-mapper and an AES crypto module However the current system is setup to generate individual files that are encrypted. What are my options for decrypting files on-the-fly in apache? I see that mod_ssl and mod_session_crypto do encryption/decryption or something similar but not exactly what I am after. I could imagine that a PerlSetOutputFilter would work with a suitable Perl script configured, and I also see mod_ext_filter so I could just fork a unix command and decrypt the file, but they both feel like a hack. I am kind of surprised that there is no mod_crypto available...or am I missing something obvious here? Presumably resource-wise the perl filter is the way to go?

• Configuration Tuning for PostgreSQL 9.1 PostGIS 1.5 Ubuntu 12.04 Server

  - by Martin

  My server performance is poor. At times SSH, top, and other features or commands are very slow to respond, taking several seconds or more. A query that normally takes 5 minutes can sometimes take 30 minutes. The database is mostly being used to do a spatial query (grid and summarize) on approximately 500GB of stored data spread between 4 tables. Restarting the server works as a temporary fix, but cannot be used as a long term solution. Any suggestions for how to diagnose and solve my performance issues?

• Can I run AD commands from a standard PowerShell script?

  - by Ben

  I am putting together a script to run post-sysprep. It should check if the machine is on the network, and if it is then it should query AD to see if a computer account exists with it's service tag (we're using these as the hostnames of the machines.) If it does exist, it should delete the account and rejoin the machine to the domain. I have got the majority of the script running, but need to run the following: Remove-ADComputer -Identity $distinguishedName How can I run this from the "standard" powershell environment? I don't want to use the AD module. (By the way - I'm on a mixed mode 2000/03 domain as we are in the process of upgrading to 2008) I'm new to PowerShell so be gentle if I'm completely missing the point! Thanks, Ben

• Excel: making line charts so the line goes through all data points

  - by Mike

  Hi I've got data based on over 50+ years for various products. Unfortunately not all products have data for each year. I've created a line chart to show the movement (quantity sold) of these products over the years. It works well, except where the data points are too far apart i.e. 1965 and then 1975. For some reason there is no line. It's not perfect data because of the missing years, but I can live with that, I just want to see the trend, and not just sporadic dots; squares or crosses. Any help or links greatly appreciated. Mike
