• no way to use opendns on pppoe connection?

  - by magisterludi

  I have an old speedtouch usb modem (revision 0) and on my desktop with xubuntu 12.04 I've configured a pppoe connection. I can connect and my ISP assign an IP address and the DNS but the primary DNS address is not reachable by ping, the secondary yes but no address is resolved then I can't surf the web. Then I want to set the open DNS but there is bo way, if I change manually /etc/resolv.conf it is rewrited by some script (there is the flag usepeerdns on the configuration script, if I exclude it there is no way to assign any DNS server because resolv.conf is not read) also if I set not writable the file changing the default permission. I changed dhclient.conf with the code prepend domain-name-servers 208.67.222.222,208.67.220.220; and now if I connect by a wifi connection to my router I'm using openDNS server but ppp does not use this script as long as I can see and the DNS server is always setted by my ISP. How can I use set DNS manually to a PPP connection? Is there any way to change it after the connection? Why NetworkManager is not able to manage my dsl connection, it seems not able to manage the dsl usb cable modem. If I use pppoeconf NetworkManager doesn't start and I have to manually delete the lines added to /etc/network/interfaces because the system is not able to start with full configuration of network If I connect a modem-router to the same line I can surf with the DNS server assigned by my ISP, I can't figure why. Some suggestion? Thanks to all

• reverse nslookup fails for single machine

  - by matt wilkie

  I have a computer on a windows Active Directory network for which reverse dns lookup fails. It doesn't matter which machine runs the lookup.

• URL protocol handlers in basic Ubuntu Desktop

  - by Hibou57

  There was a way to register URL protocol handlers with Gconf, which is now obsolete and there seems to be no way to do the same with DConf (or Gsettings, its recommended wrapper). How do one properly register an URL protocol handlers since DConf? Additionally, something looks strange to me (as I don't understand it), on my Ubuntu 12.04 The protocol apt:// should be handled by the apturl command. It is so with my Opera browser, but only because I added this specific association using the browser's configuration facility. Otherwise, in the rest of the environment: Running xdg-open apt://foo.bar opens elinks (my www-browser alternative). Running gnome-open apt://foo.bar opens the Software?Center. Opening gcong-editor, I see a key /desktop/gnome/url-handlers/apt whose value is apturl "%s" and its enable. This configuration seems to be ignored, which is reasonably expected, as GConf is considered obsolete. Opening dconf-editor, I can't see anything related to URL handlers or protocols in /desktop/gnome It looks a bit messy to my eyes (just teasing with this wording, nothing bad) What's underneath? Side note: I'm looking for something which preferably works even when the full desktop environment is not loaded, like when running an i3wm session with only gsettings-daemon (and other stuffs unrelated to this case) is loaded. Update Another way to “register” a protocol handler is with *.desktop files and their MIME-Type; ex. MimeType=application/<the-protocol>;. I found a /usr/share/applications/ubuntu-software-center.desktop with this content: [Desktop Entry] Name=Ubuntu Software Center GenericName=Software Center Comment=Lets you choose from thousands of applications available for Ubuntu Exec=/usr/bin/software-center %u Icon=softwarecenter Terminal=false Type=Application Categories=PackageManager;GTK;System;Settings; MimeType=application/x-deb;application/x-debian-package;x-scheme-handler/apt; StartupNotify=true X-Ubuntu-Gettext-Domain=software-center Keywords=Sources;PPA;Install;Uninstall;Remove;Purchase;Catalogue;Store; This one explains why gnome-open apt://foo.bar opens the Software?Center instead of apturl. So I installed this apturl.desktop in ~/.local/share/applications: [Desktop Entry] Encoding=UTF-8 Version=1.0 Type=Application Terminal=false Exec=/usr/bin/apturl %u Name=APT-URL Comment=APT-URL handler Icon= Categories=Application;Network; MimeType=x-scheme-handler/apt; After update-desktop-database and even after rebooting, both xdg-open and gnome-open still do the same and ignore this user desktop file, which is usual, should override the other in /usr/share/applications/. May be there is something special with desktop files specifying x-scheme-handler MIME type and they are not handled the usual way. The desktop-file way does not answer the question.

• Cannot authenticate to SBS 2003

  - by Lerp

  I am trying to connect my machine to my work's entirely windows network and I am having a few issues: Whenever I try to access the server, the authentication dialog just keeps popping back up. I cannot connect to the printers (it says connecting to device failed) I have tried setting up samba, winbind, kerberos, likewise open all to no avail. I have a feeling I am just setting them up wrong. My nautilus shows this when I go to Network Windows Network MASTERMAGNETS I can ping both MASTERMAGNETS.LOCAL and 192.168.0.2 after modifying my /etc/hosts james@jamesmaddison:~$ cat /etc/hosts 127.0.0.1 localhost jamesmaddison 192.168.0.2 MASTERMAGNETS.LOCAL 192.168.0.50 Sharp-Printer # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters I believe that's the correct domain (not sure if that's the correct term) as when I do nslookup MASTERMAGNETS.LOCAL I get the following: james@jamesmaddison:~$ nslookup MASTERMAGNETS.LOCAL Server: 192.168.0.2 Address: 192.168.0.2#53 Name: MASTERMAGNETS.LOCAL Address: 192.168.0.3 Name: MASTERMAGNETS.LOCAL Address: 192.168.0.2 It all worked fine before I reinstalled Ubuntu and now I just cannot get access to the server. All help is appreciated, I need to get this working or I fear I will be forced to develop in a windows environment :(

• Windows 7 - Virtualbox host only adapter doesn't get an IP

  - by Craig

  When I create a new host only network adapter, it will not set the IP address I assign to it. After I save the IP address & netmask it looks like it works (I see the Windows 7 User Account Control verification box), but the IP address doesn't get stored on the adapter. I have tried adding/removing the adapter from within virtualbox and settings the values manually in the Windows aapter settings dialogue. I am using a Windows 7 host. Does anyone know why the settings don't get saved, or how to get more information?

• Send one invalid email response to sender

  - by Kafuka

  I discovered that my postfix/dovecot configuration isn't rejecting emails. If a person sends an email to an invalid email-address, it just drops it. I am fine with this behavior since I think it discourages spammers from mining emails (I have had some success). Recently a person I did not want to talk to emailed an address I cut off and didn't receive a response back. It would have saved me some problems if they knew to call me instead of sending 50+ emails. How would I configure Dovecot/postfix to send a message back to a sender of an email address and then limit this 1 per domain or unique email. Debian Stable Linux 3.6.5-linode47 Dovecot 1.2.15 Postfix 2.7.1 PSQL - backend if that matters

• hardware addressing and configurable addressing scheme

  - by Zia ur Rahman

  basically i want to ask question about configurable addressing scheme for LAN interface hardware. i have read about it from a book, some main points are given by a configurable addressing scheme provides a mechanism that a customer can use to set a physical address.The mechanism can be manual (the switches that must be set when the interface is first installed).or an electronic memory such as an EPROM that can be downloded from the computer(what does this means). Most hardware needs to be configured only once- configuration is usually done when the hardware is first installed. Question:Suppose a network administrator configures the LAN interface hardware (assigns the address) when he installs it. Now later on if he needs to change the physical address of the device can he change it? Or in this addressing scheme the hardware can only be configured once and we can not reconfigure it later on.

• Shibboleth + IIS and Pound Reverse Proxy

  - by boburob

  Having a bit of a problem getting Shibboleth (SSO) working with ADFS and Pound. The main problem seems to be that: The website address will be https://website.domain.com Pound will then terminate the SSL and forward the traffic to the webserver on a different port (http://server.domain.com:8888) I have set up Shibboleth to protect the address http://server.domain.com:8888, which allows me to retrieve metadata and it all seems to be working fine. However the problem seems to be that ADFS is configured to protect the https website, so when Shibboleth attempts to recieve information from ADFS I get nothing except the following error: A token request was received for a relying party identified by the key 'https://msstagrevproxy.cwpintranet.com/shibboleth', but the request could not be fulfilled because the key does not identify any known relying party trust. Key: https://msstagrevproxy.cwpintranet.com/shibboleth I am not really sure how I can work around this as to retrieve the metadata from Shibboleth I have to use the https address but this does not actually exist in Shibboleth or IIS. Has anyone had any experience with this before or using any other SSO with a reverse proxy that works?

• Apache doesn't autostart because vpn isn't up yet.

  - by Col. Shrapnel

  I have a FreeBSD8 server, and VPN connection to my ISP. I use mpd5 and it works fine. A have an Apache server whch works fine, if I start it manually, after VPN is get up. But when I add it to rc.conf autostart, it fail to start, saying (49) can't assign requested address: make_sock could not bind to address I suppose it's because VPN isn't up yet and no IP address assigned to the interface which i set in the Listen directive in the httpd.conf. If i set Listen to the existing 127.0.0.1, it fail to serve wan requests. Is there a solution, either to delay apache autostart or configure it some different?

• Management VLAN Cisco Catalyst

  - by cha789

  I have configured a couple of VLANs on a Cisco Catalyst switch, i will put all the ports that clients is connected to, into these VLANs. I want to configure the native VLAN [vlan 1] as management VLAN so i can use a telnet client to connect to the switch. How can i block all but one specific IP-address to telnet into the switch? As i understand vlan 1 has many task regarding different protocols and i do not want to break that but only allow one specific IP-address to connect to the switch with a telnet client [actually the gateway ip address of the switch].

• Deployment of broadband network

  - by sthustfo

  Hi all, My query is related to broadband network deployment. I have a DSL modem connection provided by my operator. Now the DSL modem has a built-in NAT and DHCP server, hence it allocates IP addresses to any client devices (laptops, PC, mobile) that connect to it. However, the DSL modem also gets a public IP address X that is provisioned by the operator. My question is Whether this IP address X provisioned by operator is an IP address that is directly on the public Internet? Is it likely (practical scenario) that my broadband operator will put in one more NAT+DHCP server and provide IP addresses to all the modems within his broadband network. In this case, the IP addresses allotted to the modem devices will not be directly on the public Internet. Thanks in advance.

• Why is it a bad idea to use multiple NAT layers or is it?

  - by iamrohitbanga

  The computer network of an organization has a NAT with 192.168/16 IP address range. There is a department with a server that has an IP address 192.168.x.y and this server handles hosts of this department with another NAT with the IP address range 172.16/16. Thus there are 2 layers of NAT. Why don't they have subnetting instead. This would allow easy routing. I feel multiple layers of NAT can cause performance losses. Could you please help me compare the two design strategies.

• How to setup external mail addresses without external autodiscover tries?

  - by Tarnschaf

  We have a little Exchange/Outlook installation here that fetches the mails from our provider with POP3. Now to be able to send emails outside our organisation, I added another SMTP address to the Exchange User: [email protected] (Default / Reply Address) [email protected] Sending email works using the default address. But now there is an error message each time we start Outlook. Outlook tries to autodiscover using autodiscover.ourcompany.com which doesn't exist. Our autodiscover files are placed on our local server. I think all the servers are discovers, because everything works as expected. Everything except the error message on each Outlook start. (The error message is actually because of an invalid certificate but I don't see why Outlook should contact an external host at all!) So how can I solve this? Forcing Autodiscover on every Outlook client to use the local hosts? Or ist there an even better way?

• Getting bounced mail in OS X terminal

  I just noticed when launching my terminal a message "You have new mail." I would like to know if someone is trying something malicious with my email and name. The mails are all returns from the same server. There are 20 of them: N 1 MAILER-DAEMON@ussjoa Tue Nov 10 16:57 73/2522 "Undelivered Mail Retu" Each message appears to be the same, some sort of attempted registration (note: I omitted my personal email address from the following code): --6A9539564F2.1257902972/ussjoaboynton3.us.deloitte.com Content-Description: Undelivered Message Content-Type: message/rfc822 Received: by ussjoaboynton3.us.deloitte.com (Postfix, from userid 501) id 6A9539564F2; Tue, 10 Nov 2009 17:29:32 -0800 (PST) To: [email protected] Subject: Your registration informaton From: **(personal email address omitted)** Message-Id: <[email protected]> Date: Tue, 10 Nov 2009 17:29:32 -0800 (PST) First Name: as Last Name: as Email Address: as Username: as Password: F!ekUXN3 --6A9539564F2.1257902972/ussjoaboynton3.us.deloitte.com-- byte 2302Diagnostic-Code: X-Postfix; unknown user: "as" Any information to help figure out what is happening is greatly appreciated.

• Using which technique does facebook and pininterest show images?

  - by manish

  If anybody has ever noticed that when you open a image in Facebook something like this happens:- suppose you are at your homepage on Facebook:- the URL is https://www.facebook.com/ now if you open a image it gets opened in new modal like window and URL changes to:- https://www.facebook.com/photo.php?fbid=10151125374887397&set=a.338008237396.161268.36922302396&type=1&theater As far as I know in any common case a modal overlay would have kept the url in the address bar the same , My question is how does facebook / pintrest achieve this behaviour of not re-loading the whole page but still achieving the change in the address bar. Is there any jquery or javascript plugin for this?

• L'iPhone 4G dévoilé par une fuite, Apple exige la restitution de l'appareil

  L'iPhone 4G dévoilé par une fuite, Apple exige la restitution de l'appareil Voici comment un secret si bien gardé jusqu'alors s'est retrouvé à faire le tour du Web ... Un simple oubli a suffit à gâcher le grand événement que constitue d'habitude l'annonce d'un produit Apple : l'iPhone 4G devait être annoncé en juin, avant qu'un ingénieur de chez Apple ne l'oublie dans un bar près du siège... Le jeune homme aurait utilisé ce nouvel iPhone alors qu'il fêtait le 18 mars son 27ème anniversaire au «Gourmet Haus Staudt», un bar de Redwood City, non loin du siège californien d'Apple. En fin de soirée, il aurait oublié le téléphone le plus célèbre au monde sur un tabouret. Un autre fêtard anonyme l'aurait récupéré puis, se r...

• Setting Gmail as mail server

  - by Tim S.

  I’m in a slightly weird situation right now, and I don’t have sufficient knowledge to sort this myself without truly understand what I’m doing. Yesterday, I’ve registered a domain (.com) and ordered a VPS, attached to that domain. Chances are I may receive mail on my .com address to confirm the domain. Unfortunately, that domain is nothing, but an empty domain. Currently, there’s no mailserver that fetches my mail. Because I don’t have a mailserver available, I (temporarily) want to use Gmail. I prefer to add it to my existing, personal address, but I’m okay with creating a new account as well. I just want to read possible incoming mails. I’ve tried to set MX records to What do I need to do to get mail to a Gmail address? PS. I’m aware of Google, NSA, etc. PPS. I just want to receive mail. I don’t care if I can’t send via my domain. PPS. Detailed steps would be greatly appreciated, I’m a noob.

• Change Envelope From to match From header in Postfix

  - by lid

  I am using Postfix as a gateway for my domain and need it to change or rewrite the Envelope From address to match the From header. For example, the From: header is "[email protected]" and the Envelope From is "[email protected]". I want Postfix to make the Envelope From "[email protected]" before relaying it on. I took a look at the Postfix Address Rewriting document but couldn't find anything that matched my use case. (In case you're curious why I need to do this: Gmail uses the same Envelope From when sending from a particular account, no matter which From: address you choose to use. I would prefer not to disclose the account being used to send the email. Also, it messes with SPF/DMARC domain alignment - see 4.2.2 of the DMARC draft spec.)

• Why are we being twitter spammed?

  - by Tom Gullen

  This is a search relating to us: https://twitter.com/#!/search/realtime/scirra We're getting a of of new accounts tweeting: The Layers Bar - Scirra.com Firstly this is not us doing it as we're quite proud of doing everything completely whitehat. Also this tweet doesn't make any sense, "The Layers Bar" seems to be referring to a manual entry of ours. They all seem to be new accounts with no followers and no prior tweets coming in like clockwork every hour. Does anyone know why this could be happening? Could this harm us? It it possible to find out the source of this? I should mention I'm hesitant to report them all as spam because it could look like we are the culprits.

• Why do I get "General Failure" when pinging host name on a Win 7 node on the network?

  - by hydroparadise

  This is a very peculiar problem with a station on our network. The client pc is running Windows 7 Pro. What makes this problem interesting is that this client is the only node on the network that seems to be experiencing this proglem. When I try to ping a specific Win 08 server by host name, I get an IPv6 address and get General failure. But when I ping it's IPv4 address, it responds just fine. My first thought would check the DNS server the name resolutions to see what would be going on, but the problem begs the quesion, why does the station get an IPv6 address back and fails as opposed to using the IPv4 settings (which are static btw). What gives? I am including a screen shot of trying the one specific server and failing while trying another server with success. All other nodes on the network don't have problems communicating with the server the one station is having issues with.

• postfix smtp relay script

  - by Peter Sander

  I have a Postfix server and using it with Outlook (POP/SMTP). I have different sender addresses for an account. Now I want to configure a relay for a specific sender address. For example I have postfix for my main domain domain1.com. Now I have a sender address that is domain2.com. For that sender address I want that postfix to relay mail to a second SMTP server. I think that should be possible without problems. But the problem is that I have to create a SSH tunnel to the second server to connect to the SMTP server. But I cant use a persistent SSH connection so I want to know if it is possible that postfix executes some script before relaying the mail to the second SMTP server. I already found some information for executing a script when incomming emails but I only want to establish the SSH tunnel before postfix relays the mail to the second SMTP server.

• Different ways of solving problems in code.

  - by Erin

  I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very differently than most examples I see on the web. Rather then writing things like: foreach (string bar in foo) { //bar has something doen to it here } I write code that looks like this. foo.ForEach( c => c.someActionhere() ) Or var result = foo.Select( c => { //Some code here to transform the item. }).ToList(); I think my using code like above came from my love of map and reduce in python - while not exactly the same thing, the concepts are close. Now it's time for my question. What concepts do you take and move with you from language to language; that allow you to solve a problem in a way that is not the normal accepted solution in that language?
