  • How to grant standard users access to disk partitions and flash storage?

    - by JK04
    I have a partition that I need standard users (not administrators)to have read/write access to. However, this partition does not even appear to them as it does to me as an administrator. How can I make it so that standard users can read/write to this partition? It would be nice if they could have the ability to mount it if needed. I have the same problem with removable media - if I have a flash card in the computer, the standard users cannot see this storage media.

  • How to open a server port outside of an OpenVPN tunnel with a pf firewall on OSX (BSD)

    - by Timbo
    I have a Mac mini that I use as a media server running XBMC and serves media from my NAS to my stereo and TV (which has been color calibrated with a Spyder3Express, happy). The Mac runs OSX 10.8.2 and the internet connection is tunneled for general privacy over OpenVPN through Tunnelblick. I believe my anonymous VPN provider pushes "redirect_gateway" to OpenVPN/Tunnelblick because when on it effectively tunnels all non-LAN traffic in- and outbound. As an unwanted side effect that also opens the boxes server ports unprotected to the outside world and bypasses my firewall-router (Netgear SRX5308). I have run nmap from outside the LAN on the VPN IP and the server ports on the mini are clearly visible and connectable. The mini has the following ports open: ssh/22, ARD/5900 and 8080+9090 for the XBMC iOS client Constellation. I also have Synology NAS which apart from LAN file serving over AFP and WebDAV only serves up an OpenVPN/1194 and a PPTP/1732 server. When outside of the LAN I connect to this from my laptop over OpenVPN and over PPTP from my iPhone. I only want to connect through AFP/548 from the mini to the NAS. The border firewall (SRX5308) just works excellently, stable and with a very high throughput when streaming from various VOD services. My connection is a 100/10 with a close to theoretical max throughput. The ruleset is as follows Inbound: PPTP/1723 Allow always to 10.0.0.40 (NAS/VPN server) from a restricted IP range >corresponding to possible cell provider range OpenVPN/1194 Allow always to 10.0.0.40 (NAS/VPN server) from any Outbound: Default outbound policy: Allow Always OpenVPN/1194 TCP Allow always from 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) OpenVPN/1194 UDP Allow always to 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) Block always from NAS to any On the Mini I have disabled the OSX Application Level Firewall because it throws popups which don't remember my choices from one time to another and that's annoying on a media server. Instead I run Little Snitch which controls outgoing connections nicely on an application level. I have configured the excellent OSX builtin firewall pf (from BSD) as follows pf.conf (Apple App firewall tie-ins removed) (# replaced with % to avoid formatting errors) ### macro name for external interface. eth_if = "en0" vpn_if = "tap0" ### wifi_if = "en1" ### %usb_if = "en3" ext_if = $eth_if LAN="{10.0.0.0/24}" ### General housekeeping rules ### ### Drop all blocked packets silently set block-policy drop ### all incoming traffic on external interface is normalized and fragmented ### packets are reassembled. scrub in on $ext_if all fragment reassemble scrub in on $vpn_if all fragment reassemble scrub out all ### exercise antispoofing on the external interface, but add the local ### loopback interface as an exception, to prevent services utilizing the ### local loop from being blocked accidentally. ### set skip on lo0 antispoof for $ext_if inet antispoof for $vpn_if inet ### spoofing protection for all interfaces block in quick from urpf-failed ############################# block all ### Access to the mini server over ssh/22 and remote desktop/5900 from LAN/en0 only pass in on $eth_if proto tcp from $LAN to any port {22, 5900, 8080, 9090} ### Allow all udp and icmp also, necessary for Constellation. Could be tightened. pass on $eth_if proto {udp, icmp} from $LAN to any ### Allow AFP to 10.0.0.40 (NAS) pass out on $eth_if proto tcp from any to 10.0.0.40 port 548 ### Allow OpenVPN tunnel setup over unprotected link (en0) only to VPN provider IPs ### and port ranges pass on $eth_if proto tcp from any to a.b.8.0/24 port 1194:1201 ### OpenVPN Tunnel rules. All traffic allowed out, only in to ports 4100-4110 ### Outgoing pings ok pass in on $vpn_if proto {tcp, udp} from any to any port 4100:4110 pass out on $vpn_if proto {tcp, udp, icmp} from any to any So what are my goals and what does the above setup achieve? (until you tell me otherwise :) 1) Full LAN access to the above ports on the mini/media server (including through my own VPN server) 2) All internet traffic from the mini/media server is anonymized and tunneled over VPN 3) If OpenVPN/Tunnelblick on the mini drops the connection, nothing is leaked both because of pf and the router outgoing ruleset. It can't even do a DNS lookup through the router. So what do I have to hide with all this? Nothing much really, I just got carried away trying to stop port scans through the VPN tunnel :) In any case this setup works perfectly and it is very stable. The Problem at last! I want to run a minecraft server and I installed that on a separate user account on the mini server (user=mc) to keep things partitioned. I don't want this server accessible through the anonymized VPN tunnel because there are lots more port scans and hacking attempts through that than over my regular IP and I don't trust java in general. So I added the following pf rule on the mini: ### Allow Minecraft public through user mc pass in on $eth_if proto {tcp,udp} from any to any port 24983 user mc pass out on $eth_if proto {tcp, udp} from any to any user mc And these additions on the border firewall: Inbound: Allow always TCP/UDP from any to 10.0.0.40 (NAS) Outbound: Allow always TCP port 80 from 10.0.0.40 to any (needed for online account checkups) This works fine but only when the OpenVPN/Tunnelblick tunnel is down. When up no connection is possbile to the minecraft server from outside of LAN. inside LAN is always OK. Everything else functions as intended. I believe the redirect_gateway push is close to the root of the problem, but I want to keep that specific VPN provider because of the fantastic throughput, price and service. The Solution? How can I open up the minecraft server port outside of the tunnel so it's only available over en0 not the VPN tunnel? Should I a static route? But I don't know which IPs will be connecting...stumbles How secure would to estimate this setup to be and do you have other improvements to share? I've searched extensively in the last few days to no avail...If you've read this far I bet you know the answer :)

  • Internet TV streaming applications

    - by mark kirby
    Are there any programs for Ubuntu that can pull TV streams from the Internet ? For example like on a blu-ray player you get BBC iplayer and hulu and youtube as apps, so is there an application that can do this ? I know XMBC can but its to fiddly and resource hungry, I just want the net TV apps and not the full media center. Boxee was great for this, it was a media center but had an interface for the apps not just sticking them in some strange menu like XBMC. Please let me know of anything you know of

  • Unable to boot to Ubuntu

    - by nsk
    Just got a new laptop and removed Windows 8 and installed 13.10 using LiveUSB. Initially it was booting to "No boot media" but I was able to resolve it with boot-repair. I realized some of the items I need isn't supported on 13.10, so attempted to install 13.04 instead. Now without LiveUSB, the laptop just boots to "No boot media" but boot repair doesn't seem to be fixing it. Tried going back to 13.10, but no dice. After boot repair it says "Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/grubx64.efi file!". GParted shows sda1 has the boot flag. Using Toshiba Satellite P50. Secure Boot disabled. UEFI enabled. Any help would be highly appreciated. http://paste.ubuntu.com/6366556/

  • How to Automatically run two commands after login?

    - by Covi
    I have these two commands that I need to manually run every time after login: autossh -M 2000 -N -f -q -D 127.0.0.1:7070 [email protected] and sudo mkdir /media/C sudo mount /dev/sda2 /media/C I'd like to make them automatically run every time I boot and login to my computer. I'm currently using 10.04LTS. BTW, I only vaguely know what init.d or runlevel mean. But I still prefer to know a command-line based way to achieve this, not a fancy GUI way. Also, the autossh will only succeed after Ubuntu automatically detect and connect to my network, so should we let it retry infinitely until successfully executed? Thank you!

  • RewriteRule for URLs with spaces

    - by Robert Cailliau
    My site's pages are in multiple languages whereby each language version shares its media (images) with the other language versions. I place all versions and the media in a single directory with the same name. E.g. pages mypage-en.html, mypage-fr.html etc. will sit in directory mypage. The directory path suffices to reference a page: h t t p : //....../mypage/ is good enough, there is no need for h t t p : //....../mypage/mypage-en/html A rewrite with RewriteRule ^(.*)/([a-zA-Z0-9]+)/?$ /$1/$2/$2-en.html lets me use the shorter form. But what if the name mypage contains spaces (which some do) ? I want h t t p : //....../my page/ to lead to h t t p : //....../my page/my page.html Using RewriteRule ^(.*)/([a-zA-Z0-9|\s]+)/?$ /$1/$2/$2-en.html did not work. Any hints welcome. (please do not ask me why I want to do this, nor tell me I should not use spaces in file names)

  • Images missing after moving Django to new server

    - by miszczu
    I'm moving Django project to new server. I'm newbie in Django, and I don't know where should be upload folder. There are all images which should be displayed on website. In config file I haven't seen upload folder I could specify, so I'm guessing it always should be the same location for django projects or I just can't find it. Locations are saved in database. When I've put uploaded files into media folder, so url was like domain.co.uk/media/upload/media/images/year/month/day/image_name.ext and the same is on the old website, images on website ware still missing. All images are visible if I put url by hand, but django doesn't seems to see files. Also I check django log file: 2012-05-30 09:13:33,393 ERROR render: Thumbnail tag failed: [in /usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py (line 49)] Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 45, in render return self._render(context) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 97, in _render file_, geometry, **options File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/base.py", line 50, in get_thumbnail cached = default.kvstore.get(thumbnail) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 25, in get return self._get(image_file.key) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 123, in _get value = self._get_raw(add_prefix(key, identity)) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/cached_db_kvstore.py", line 26, in _get_raw value = KVStoreModel.objects.get(key=key).value File "/usr/lib/python2.6/site-packages/django/db/models/manager.py", line 132, in get return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 344, in get num = len(clone) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 82, in __len__ self._result_cache = list(self.iterator()) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 273, in iterator for row in compiler.results_iter(): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 680, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 735, in execute_sql cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/util.py", line 34, in execute return self.cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute return self.cursor.execute(query, args) File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue DatabaseError: (1146, "Table 'thumbnail_kvstore' doesn't exist") 2012-05-30 09:13:33,396 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = office-closed-message ); args=(True, u'office-closed-message') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,399 DEBUG execute: (0.000) SELECT `menus_menu`.`id`, `menus_menu`.`name`, `menus_menu`.`slug`, `menus_menu`.`base_url`, `menus_menu`.`description`, `menus_menu`.`enabled` FROM `menus_menu` WHERE (`menus_menu`.`enabled` = True AND `menus_menu`.`slug` = about ); args=(True, u'about') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,401 DEBUG execute: (0.000) SELECT `menus_menuitem`.`id`, `menus_menuitem`.`menu_id`, `menus_menuitem`.`title`, `menus_menuitem`.`url`, `menus_menuitem`.`order` FROM `menus_menuitem` INNER JOIN `menus_menu` ON (`menus_menuitem`.`menu_id` = `menus_menu`.`id`) WHERE `menus_menu`.`slug` = about ORDER BY `menus_menuitem`.`order` ASC; args=(u'about',) [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,404 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = contactdetails-footer ); args=(True, u'contactdetails-footer') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] I checked database and there is no table calls thumbnail_kvstore, but I have database backup, and in backup files this table doesn't exist.

  • SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database

    - by Pinal Dave
    In the yesterday’s blog post we have seen that it is extremely easy to install the NuoDB database on your local machine. Now that the application is properly set up, let us explore NuoDB a bit more and get you familiar with the how it works and what the important areas of the NuoDB are that you should learn. As we have already installed NuoDB, now we will quickly start with two of the important areas in NuoDB: 1) Admin and 2) Explorer. In this blog post I will explore how the Admin Section of the NuoDB Console works.  In the next blog post we will learn how the Explorer Section works. Let us go to the NuoDB Console by typing the following URL in your browser: http://localhost:8080/ It will bring you to the following screen: On this screen you can see a big Start QuickStart button. Click on the button and it will bring you to following screen. On this screen you will find very important information about Domain and Database Settings. It is our habit that we do not read what is written on the screen and keep on clicking on continue without reading. While we are familiar with most wizards, we can often miss the very important message on the screen. Please note the information of Domain Settings and Database Settings from the following screen before clicking on Create Database. Domain Settings User: quickstart Password: quickstart Database Settings User: dba Password: goalie Database: test Schema: HOCKEY Once you click on the Create Database button it will immediately start creating sample database. First, it will start a Storage Manager and right after that it will start a Transaction Engine. Once the engine is up, it will Create a Schema and Sample Data. On the success of the creating the sample database it will show the following screen. Now is the time where we can explore the NuoDB Admin or NuoDB Explorer. If you click on Admin, it will first show following login screen. Enter for the username “domain” and for the password “bird”. Alternatively you can enter “quickstart”  twice for username and password.  It works as too. Once you enter into the Admin Section, on the left side you can see information about NuoDB and Admin Console and on the right side you can see the domain overview area. From this Administrative section you can do any of the following tasks: Create a view of the entire domain Add and remove databases Start and stop NuoDB Transaction Engines and Storage Managers Monitor transaction across all the NuoDB databases On the right side of the Admin Section we can see various information about a particular NuoDB domain. You can quickly view various alerts, find out information about the number of host machines that are provisioned for the domain, and see the number of databases and processes that are running in the domain. If you click on the “1 host” link you will be able to see various processes, CPU usage and other information. In the Processes Section you can see that there are two different types of processes. The first process (where you can see the floppy drive icon) represents a running Storage Manager process and the second process a running Transaction Engine process. You can click on the links for the Storage Manager and Transaction Engine to see further statistical details right down to the last byte of the data. There are various charts available for analysis as well. I think the product is quite mature and the user can add different monitor charts to the Admin section. Additionally, the Admin section is the place where you can create and manage new databases. I hope today’s tutorial gives you enough confidence that you can try out NuoDB and checkout various administrative activities with the database. I am personally impressed with their dashboard related to various counters. For more information about how the NuoDB architecture works and what a Storage Manager or Transaction Engine does, check out this short video with NuoDB CTO Seth Proctor:  In the next blog post, we will try out the Explorer section of NuoDB, which allows us to run SQL queries and write SQL code.  Meanwhile, I strongly suggest you download and install NuoDB and get yourself familiar with the product.

  • A SharePoint Developer&rsquo;s Toolchest

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). When we develop for SharePoint, we end up using many tools, third party or Microsoft, to facilitate our development. What are some of your favorite tools? Mine are as below - 1. Reflector: When I saw reflector, I was pretty convinced that a tool better and more useful than it doesn’t exist. Well I was wrong! Redgate took over reflector and they still offer it as a free version, but they have a paid version called reflector pro. It lets you debug third party source code, as if you had the source code. Brilliant! Who needs documentation anymore when you have real code? 2. ULS Viewer: It is no secret, reading ULS logs is a pain in the rear. Well, not so with ULS Viewer, which does work with SharePoint 2007 as well. But it’s just way cooler with SharePoint 2010. You know when you get an error in SharePoint 2010 it shows you an error like as below: Well, the ULS Viewer will allow you to set filtering critereon, allowing you to immediately zero in, into an error, across multiple WFEs even. Also there are numerous other facilities built into the tool, such as advanced filtering, critical error notifications, etc. A must have! You can read the documentation of the ULSViewer here. 3. SPDisposeCheck: Did you know that the MySite object is strange? What is strange about it? That you have to dispose it even if you didn’t create it!? Well who the hell remembers all that! Honestly I do! And you should too. But there is a tool to help you sanitize your code. And that is SPDisposeCheck. You run it against your DLL or EXE, and it will give you suggestions on where you might have missed calling dispose on an object. You still have to use your head, but having this tool helps. 4. DebugView: Debugging for SharePoint can be difficult sometimes. Sometimes your breakpoints don’t get hit. And while you can try and make them hit, it is sometimes easier to just write a bunch of Debug.WriteLines, and catch them from an external application such as DebugView. You simply use your code, and DebugView will catch all the Debug.WriteLine’s in your code like this - 5. BGInfo: One annoying thing about SharePoint projects, it causes the number of servers to multiply like bunnies. As I’m RDP’ing into many computers trying to diagnose a crazy issue, sometimes it becomes hard to remember which machine is which. BGInfo puts all that on the wallpaper, alongwith a bunch of other useful info. A bit like this - 5. WSPBuilder: SharePoint 2007 only, but I think there maybe a version for SP2010 coming later. I think the VS2010 tools for SP2010 development are quite nice, so WSPBuilder, well so far I don’t miss it. But lets see what WSPBuilder for 2010 brings – I haven’t seen it yet. However, I want to confidently assert that WSPBuilder for SP2007 is simply awesome. 6. SharePoint Manager: The SharePoint Manager 2010 is a SharePoint object model explorer. It enables you to browse every site on the local farm and view every property. It also enables you to change the properties. The VS2010 dev tools now include a server explorer, which show you a subset of properties in read-only. I would LOVE to see SharePoint manager like functionality built into VS2010. SharePoint Manager, a total must-have. Comment on the article ....

  • SQL SERVER – ASYNC_IO_COMPLETION – Wait Type – Day 11 of 28

    - by pinaldave
    For any good system three things are vital: CPU, Memory and IO (disk). Among these three, IO is the most crucial factor of SQL Server. Looking at real-world cases, I do not see IT people upgrading CPU and Memory frequently. However, the disk is often upgraded for either improving the space, speed or throughput. Today we will look at another IO-related wait type. From Book On-Line: Occurs when a task is waiting for I/Os to finish. ASYNC_IO_COMPLETION Explanation: Any tasks are waiting for I/O to finish. If by any means your application that’s connected to SQL Server is processing the data very slowly, this type of wait can occur. Several long-running database operations like BACKUP, CREATE DATABASE, ALTER DATABASE or other operations can also create this wait type. Reducing ASYNC_IO_COMPLETION wait: When it is an issue related to IO, one should check for the following things associated to IO subsystem: Look at the programming and see if there is any application code which processes the data slowly (like inefficient loop, etc.). Note that it should be re-written to avoid this  wait type. Proper placing of the files is very important. We should check the file system for proper placement of the files – LDF and MDF on separate drive, TempDB on another separate drive, hot spot tables on separate filegroup (and on separate disk), etc. Check the File Statistics and see if there is a higher IO Read and IO Write Stall SQL SERVER – Get File Statistics Using fn_virtualfilestats. Check event log and error log for any errors or warnings related to IO. If you are using SAN (Storage Area Network), check the throughput of the SAN system as well as configuration of the HBA Queue Depth. In one of my recent projects, the SAN was performing really badly and so the SAN administrator did not accept it. After some investigations, he agreed to change the HBA Queue Depth on the development setup (test environment). As soon as we changed the HBA Queue Depth to quite a higher value, there was a sudden big improvement in the performance. It is very likely to happen that there are no proper indexes on the system and yet there are lots of table scans and heap scans. Creating proper index can reduce the IO bandwidth considerably. If SQL Server can use appropriate cover index instead of clustered index, it can effectively reduce lots of CPU, Memory and IO (considering cover index has lesser columns than cluster table and all other; it depends upon the situation). You can refer to the following two articles I wrote that talk about how to optimize indexes: Create Missing Indexes Drop Unused Indexes Checking Memory Related Perfmon Counters SQLServer: Memory Manager\Memory Grants Pending (Consistent higher value than 0-2) SQLServer: Memory Manager\Memory Grants Outstanding (Consistent higher value, Benchmark) SQLServer: Buffer Manager\Buffer Hit Cache Ratio (Higher is better, greater than 90% for usually smooth running system) SQLServer: Buffer Manager\Page Life Expectancy (Consistent lower value than 300 seconds) Memory: Available Mbytes (Information only) Memory: Page Faults/sec (Benchmark only) Memory: Pages/sec (Benchmark only) Checking Disk Related Perfmon Counters Average Disk sec/Read (Consistent higher value than 4-8 millisecond is not good) Average Disk sec/Write (Consistent higher value than 4-8 millisecond is not good) Average Disk Read/Write Queue Length (Consistent higher value than benchmark is not good) Read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • Using 3G/UMTS in Mauritius

    After some conversation, threads in online forum and mailing lists I thought about writing this article on how to setup, configure and use 3G/UMTS connections on Linux here in Mauritius. Personally, I can only share my experience with Emtel Ltd. but try to give some clues about how to configure Orange as well. Emtel 3G/UMTS surf stick Emtel provides different surf sticks from Huawei. Back in 2007, I started with an E220 that wouldn't run on Windows Vista either. Nowadays, you just plug in the surf stick (ie. E169) and usually the Network Manager will detect the new broadband modem. Nothing to worry about. The Linux Network Manager even provides a connection profile for Emtel here in Mauritius and establishing the Internet connection is done in less than 2 minutes... even quicker. Using wvdial Old-fashioned Linux users might not take Network Manager into consideration but feel comfortable with wvdial. Although that wvdial is primarily used with serial port attached modems, it can operate on USB ports as well. Following is my configuration from /etc/wvdial.conf: [Dialer Defaults]Phone = *99#Username = emtelPassword = emtelNew PPPD = yesStupid Mode = 1Dial Command = ATDT[Dialer emtel]Modem = /dev/ttyUSB0Baud = 3774000Init2 = ATZInit3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0Init4 = AT+cgdcont=1,"ip","web"ISDN = 0Modem Type = Analog Modem The values of user name and password are optional and can be configured as you like. In case that your SIM card is protected by a pin - which is highly advised, you might another dialer section in your configuration file like so: [Dialer pin]Modem = /dev/ttyUSB0Init1 = AT+CPIN=0000 This way you can "daisy-chain" your command to establish your Internet connection like so: wvdial pin emtel And it works auto-magically. Depending on your group assignments (dialout), you might have to sudo the wvdial statement like so: sudo wvdial pin emtel Orange parameters As far as I could figure out without really testing it myself, it is also necessary to set the Access Point (AP) manually with Orange. Well, although it is pretty obvious a lot of people seem to struggle. The AP value is "orange". [Dialer orange]Modem = /dev/ttyUSB0Baud = 3774000Init2 = ATZInit3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0Init4 = AT+cgdcont=1,"ip","orange"ISDN = 0Modem Type = Analog Modem And you are done. Official Linux support from providers It's just simple: Forget it! The people at the Emtel call center are completely focused on the hardware and Mobile Connect software application provided by Huawei and are totally lost in case that you confront them with other constellations. For example, my wife's netbook has an integrated 3G/UMTS modem from Ericsson. Therefore, no need to use the Huawei surf stick at all and of course we use the existing software named Wireless Manager instead of. Now, imagine to mention at the help desk: "Ehm, sorry but what's Mobile Connect?" And Linux after all might give the call operator sleepless nights... Who knows? Anyways, I hope that my article and configuration could give you a helping hand and that you will be able to connect your Linux box with 3G/UMTS surf sticks here in Mauritius.
