• How should one refer to their social network profiles in prints?

  - by Omne

  In case a person has many different social network profiles, what is the proper way of referring to those profiles in a work that is meant to be printed or may be viewed as an image? For example one owns the username "CoolCompany" on Facebook, Twitter, Google+ and other websites. Should they provide a URL for each profile? for example: Facebook.com/CoolCompany Twitter.com/CoolCompany ... I often notice that in videos or on TV people may only use the logos but I believe it is not very useful, specially in case that the audience are unfamiliar with a social network... Is it acceptable to provide the logos or names of the networks and mention the username only once like this: Facebook & Twitter: @CoolCompany Or Facebook & Twitter: /CoolCompany

• Cycles through black screen on login after changing password

  - by John L

  On my laptop, I forgot the password to my Ubuntu partition, so I logged into the root command shell on the recovery start up option in GRUB so that I could change the password. On my first attempt to change my user password, I got this error: root@username-PC:~# passwd username (*not my actual user name*) Enter new UNIX password: Retype new UNIX password: passwd: Authentication token manipulation error passwd: password unchanged After doing some research, I discovered that I was stuck as read only on the file system, so I ran the following command to remount the file partition as read/write: mount -rw -o remount / Afterwards, I change my user password using passwd and it was changed successfully. I restarted my laptop and tried to login using the new password but the only thing that happened was after entering my password it flashed to a black screen with some text that I couldn't make out except for "Ubuntu 12.04" then another black screen half a second later, and finally back to the login screen. Repeated attempts to login results in only this action.

• Proper fstab entry to mount a samba share in 12.04

  - by JPbuntu

  I am a little confused on the proper fstab entry for a samba share in Ubuntu 12.04 I can get the drive to mount manually by using: sudo mount -t cifs //192.168.2.2/raid_drive /mnt/homeserver -o username=jon,password=password So I tried putting this in fstab: //192.168.2.2/raid_drive /mnt/homeserver cifs username=jon,password=password,iocharset=utf8,mode=0777,dir_mode=07??77 0 0 Which gives me this error in syslog: kernel: [ 2217.925354] CIFS: Unknown mount option mode kernel: [ 2217.936345] CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3 This guide says to use smbfs although I believe smbfs is deprecated? What is a common fstab configuration for a samba share in Ubuntu 12.04? EDIT: Using the accepted answer below I was initially getting this error message (from dmesg): [ 45.520883] CIFS VFS: Error connecting to socket. Aborting operation [ 45.520990] CIFS VFS: cifs_mount failed w/return code = -115 although it turns out this was due to network connectivity issues, and not related to improper fstab entry.

• Should plus be encoded in mailto: hyperlinks?

  - by Jeff Atwood

  When placing an email address with an address tag (aka sub-addressing) in a mailto hyperlink … <a href="mailto:[email protected]">mail us now!</a> … should the plus in the email be URL encoded? <a href="mailto:username%[email protected]">mail us now!</a> I can't figure this out, and the documentation is conflicting. Our real world tests have produced mixed results as well, making it even more confusing.

• MacOSX VirtualHost: "You don't have permission to access / on this server" error

  - by David Casillas

  The Apache instalation of MacOSX is running Ok. I have tried to create a VirtualHost called test.local, but as soon as I uncomment from /private/etc/apache2/httpd.conf the line Include /private/etc/apache2/extra/httpd-vhosts.conf , and try to access test.local virtualhost I get an error "You don't have permission to access / on this server".

• How do I reset my Ubuntu 12.10 password?

  - by Salvador Yniguez

  So my sister gave me this old laptop that has Ubuntu 12.10. The problem is that she has a username administrator password, but she forgot it. I've tried using GRUB and launching recovery mode and using the root shell prompt. And I type the "passwd username" command, and it tells me to type the new UNIX password, but when I try to type a new password it's like my keyboard doesn't even work. It types nothing. What's the problem? Why does my keyboard not type anything when I try to reset the UNIX password? It always works perfectly fine. I'm grateful for any help, thank you.

• WebLogic not reading boot.properties 11.1.1.x

  - by James Taylor

  In WebLogic 11.1.1.1 the boot.properties file was stored in the $MW_HOME/user_projects/domains/[domain] directory. It would be read at startup and there would be no requirement to enter username and password. In later releases the location has changed to $MW_HOME/user_projects/domains/[domain]/servers/[managed_server]/security In most instances you will need to create the security directory If you want to specify a custom directory add the following to the startup scripts for the server. -Dweblogic.system.BootIdentityFile=[loc]/boot.properties create a boot.properties file using the following entry username=<adminuser> password=<password>

• In a SSL web application, what would be the vulnerabilities of using session based authentication?

  - by Thomas C. G. de Vilhena

  I'm not sure the term even exists, so let me explain what I mean by "session based authentication" through some pseudo-code: void PerformLogin(string userName, string password) { if(AreValidCredentials(userName, password)) { Session.Set("IsAuthenticated", true); } else { Message.Show("Invalid credentials!"); } } So the above method simply verifies the provided credentials are valid and then sets a session flag to indicate that the session user is authenticated. Under plain HTTP that is obviously unsafe, because anyone could hijack the session cookie/querystring and breach security. However, under HTTPS the session cookie/querystring is protected because client-server communication is encrypted, so I believe this authentication approach would be safe, wouldn't it? I'm asking this because I want to know how authentication tickets can improve web applications security. Thanks in advance!

• How to deal with social login

  - by Matteo Pagliazzi

  In my new web app I'm going to allow social login through Twitter (maybe), Facebook and Google and I'm in search of the best way to do it. Actually I'm using Rails with Devise + Omniauth and this is the problem: Should I ask the user to choose a password so that he can login without a social network? Or maybe the user should be able to set a password if he want (for example when editing his account?) The second way seems the best one but since Twitter doesn't provide user email and google doesn't provide an username I'll probably have to ask the user for username/email when he log in so in that case I may also ask for the password... waht do you think?

• Can't Enter Password in Recovery Mode

  - by Mike Lentini

  When I go into recovery mode to get to the command line, I enter "telinit 3" to drop out of root. This works on my desktop, but on my laptop it asks for my username and password, then I hit enter and the first letter of my password appears and it doesn't log me in. It then proceeds to ask me for my username and password again, and the issue continues. Am I doing something wrong? Is this a known issue with a solution? EDIT: Worked around this by going into /etc/default/grub and setting it to boot in text mode. Still would like a solution for this though.

• Connecting to an Amazon AWS database [closed]

  - by Adel

  so I'm a bit overwhelmed/bewildered by the whole concept of networking/remote-desktop , etc. The context is that - in my company I need to access a remote database. The standard way I use is to first connect using a VPN-Client( called Shrew Soft Access manager), then once that says: "network device configured tunnel enabled" I'm good to connect using windows "Remote Desktop Connection" . But now our company set up an Amazon AWS database, and I'm told I need to connect, and I ony need to use RDP. So I tried the standard windows one - but it doesn't work. On wikipedia , I looked up remote desktop sftware and downloaded one called VNC Viewer. but it doesn't work. Any advice/tips/comments appreciated EDIT: YAYA! I finally got a little more connected . I had to use my username as a fully qualified name: Computer: XYZ.XYZ.XYZ.XYZ USERNAME: XYZ.XYZ.XYZ.XYZ\aazzam

• java.net.SocketException: Connection reset; No available router to destination

  - by adejuanc

  Sometimes a Weblogic Server will be unreachable, there could be several reasons, the server is hang, down, and thus not responding to a ping, or it could be related to a network issue.A possible point of failure in the network layer are firewalls. You should contact your network team if you have following messages: java weblogic.Admin -adminurl t3://adminServer.mydomain.com:7777 -username admin -password lockdown PINGFailed to connect to t3://adminServer.mydomain.com:7777: Destination unreachable; nested exception is:java.net.SocketException: Connection reset; No available router to destination A possible work around for the ping command is to use the HTTP protocol, instead of the t3 protocol. To enable this you must configure WebLogic to do HTTP tunneling. To enable, access the administration console, click servers-> server you want to reach-> protocols -> http -> enable Tunneling. no restart is necessary. And then, following command will work: java weblogic.Admin -adminurl http://adminServer.mydomain.com:7777 -username igmadmin -password l0ckdown PING

• How to create a shared folder using command line on a server

  - by sadmicrowave

  After following the tutorial here I ran into a problem. Here is what I did. On my server I installed nfs-kernel-server and edited the /etc/exports file to include the folder I want to share: /var *(rw,sync) On my client machine I edited my fstab file to include share: //128.251.xxx.xxx/var/ ~/uslonsweb003 nfs #username=[username],password=[password], 0 0 Entered command: sudo mount -a which gives this error: mount.nfs: remote share not in 'host:dir' format Where did I go wrong with this setup? Also if there is a better way (using command line) to setup a folder share on an Ubuntu 10.10 server that will be accessed by other linux and windows machines please let me know. UPDATE: The mapped drive is now not letting me create,edit,delete files or folders (readonly access) my configuration is as follows: client fstab file: 128.251.xxx.xxx:/var /home/coreyf/uslonsweb003 nfs rw,hard,intr, 0 0 server exports file: /var *(rw,no_root_squash,sync,no_subtree_check) UPDATE 2: Using Allans solution my drive mounted correctly however after putting rw,intr as my additional parameters I cannot create, edit and delete folders/files.

• How to host a site in another site - with little or no coding

  - by tunmise fasipe

  SUMMARY: All of these happens on Site A User visits site A User enter username and password User click on Login Button User authenticated on Site B behind the scene User is shown a page on Site A that contains his/her profile from Site B as layout/styled from Site B User can click links in the Profile page that links to other area in Site B Meaning: Session has to be maintained somehow I have web application where I store users' password and username. If you logon to this site, you can login with the password and username to have access to your profile. There is another option that requires you to login to my site from your site and have your profile displayed within your site. This is because you might already have a site that your clients know you with. This link is close to what I want to do: http://aspmessageboard.com/showthread.php?t=235069 A user on Site A login to Site B and have the information on site B showing in site A. He should not know whether Site B exists. It should be as if everything is happening in Site A This latter part is what I don't know to implement. I have these ideas: Have a fixed IFrame within your site to contain my site: but I am concerned about size/layout since different clients have different layout/size for their content section. I am thinking of how to maintain session too A webservice: I don't know how feasible this is since the Password and ID are on my server. You may have to send them back and forth. It means client would have to code with my API. But I am not just returning data, I have to show them a page that contains the profile details OpenID, Single-SignOn: Just guessing - but the authentication and data resides on my server. there is nothing to access on your side in this case Examples: like login into facebook within my site and still be able to do post updates, receive notifications Facebook implement some of these with IFrame e.g. the Like button *NOTE: * I have tested the IFrame option. It worked but I still have to remove my site specific content like my page Banner, Side Navigation etc. I was able to login normally as if I was actually on the site. This show my GUI but - style sheet was missing - content not styled with CSS - Any relative url won't work. It would look for that resource relative to the current server. Unless I change links to absolute - Clicking on the LogIn button produces this error: The state information is invalid for this page and might be corrupted. UPDATE: I was reading about REST webservice few days ago and I got this idea: What about the idea of returning an XML from a webservice [REST or SOAP] and providing an XSLT (that I can provide) to display it. Thus they won't have to do much coding?

• Trying to configure samba share with office server

• Are two database trips reasonable for a login system?

  - by Randolph Potter

  I am designing a login system for a project, and have an issue about it requiring two trips to the database when a user logs in. User types in username and password Database is polled and password hash is retrieved for comparative purposes (first trip) Code tests hash against entered password (and salt), and if verified, resets the session ID New session ID and username are sent back to the database to write a row to the login table, and generate a login ID for that session. EDIT: I am using a random salt. Does this design make sense? Am I missing something? Is my concern about two trips unfounded? Comments and suggestions are welcome.

• Enabling/disabling proftpd accounts with PHP and WHM

  - by Brett G

  I have a VPS with WHM/CPanel which is being used just by me. It's utilizing proftpd. I'd like to, via a PHP script, disable/enable a specific FTP account. I've done this by having PHP call a bash script which removes/adds the user account line to /etc/proftpd/USERNAME password file. However, in order to do this I have to give other write rights to /etc/proftpd/USERNAME. This isn't ideal, and I'd be willing to do it another way. It also seems like WHM is automatically resetting these permissions on a regular basis. Does anybody have any ideas on a better way to deal with this?

• Connecting to VPN / proxy with different port number

  - by user779159

  I have an IP address, port, username, and password for one of those VPN / proxy services that allows you to use an IP address other than what your ISP gives you, but in the 'Edit Connections VPN' GUI I don't see where to enter a port. I enter the IP address under 'Gateway' and the username and password where it asks for it, but it doesn't work. I try to enter it with the IP address ending with a colon, followed by the port, but that doesn't work either (e.g. "1.1.1.1:9999"). Any idea how I could make it work? I'm using Ubuntu 12.04 LTS. Thanks.

• Unity dash search

  - by To Do

  I have my personal folders to a different partition other than home, I had a series of symlinks in my home folder pointing to the folders on the other partition. This was causing multiple entries in Dash search do I modified my ~/.config/user-dirs.dirs file pointing them to the folders on the second partition. The issue is that when I search for any one of these folders in Dash, I still get two entries, one pointing the folder and another that points to the /home/username/Documents folder. If I click on this link I get a Could not find /home/username/Documents error. Why is this and how do I delete these entries from Dash's records? If deleting records is not possible, is there a way to "reindex" the dash search database?

• Cannot connect to windows share

  - by BCqrstoO

  I've been going through and pouring over resource for the past few hours and I cannot get my box to connect to my friends network drive. My friend doesn't use linux, but he's setup the network share like this: DPR:\\name\images and he's given me the username and password which I've verified is correct. It is located on 192.168.0.2 sudo mount -t cifs -o username=***,password=*** //name/images /media/name/ sudo mount.cifs //192.168.0.2/name/images /media/name/ -o credentials=~/name.credentials (I've confirmed that ~/name.credentials does have the correct credentials as well) Regardless of what I attempt I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I'm not sure what I'm doing wrong, but it's probably really simple and stupid. Thanks to any/all in advance. EDIT: I don't know if this helps, but I'm running Ubuntu 14.04.

• How can I change my "Desktop bar"?

  - by d_Joke

  The problem: In Gnome 3.4 when I click the main menu, it's white. The text of the menu is also white. Original text: I have a problem. When I installed the new version of Gnome (3.4) the "Desktop bar" (I'm sorry, I don't know what's the real name of that bar, but is the bar on the top on Ubuntu 11.10) every time I click on the username icon, or the battery, etc., the menu comes on gray or white and the letters are white. I know maybe this is a stupid question but it annoys me. Besides, my username doest not appear on the login screen. I tried to reset my settings, I delete gnome, and check the Unsettings and CompizConfig but the problem is still there. Maybe I miss something on the process of looking on any configuration tool but I don't think so... Sorry if the question is something basic or even stupid but I'm new on Ubuntu and I'm experimenting whit it.

• What is a good way to keep track of strings for dictionary lookups?

  - by Justin

  I am working through the Windows 8 app tutorial. They have some code about saving app data like so: private void NameInput_TextChanged(object sender, TextChangedEventArgs e) { Windows.Storage.ApplicationDataContainer roamingSettings = Windows.Storage.ApplicationData.Current.RoamingSettings; roamingSettings.Values["userName"] = nameInput.Text; } I have worked with C# in the past and found that things like using constant string values (like "userName" in this case) for keys could get messy because auto-complete did not work and it was easy to forget if I had made an entry for a setting before and what it was called. So if I don't touch code for awhile I end up accidentally creating multiple entries for the same value that are named slightly differently. Surely there is a better way to keep track of the strings that key to those values. What is a good solution to this problem?
