It is possible to replace your Microsoft Lync client by a free IM client : Pidgin with a special enabled-plugin : SIPE
To download the latest win32 Pidgin version :
Download the SIPE plugin compiled for Windows :
Then, install your new IM client by launching the installer. Do the same for the SIPE client. Now, add your Lync account into Pidgin by providing the following information :
Protocol : Office Communicator
Username : your professional email address
Login user : your_firm_Active_Directory_domain_name\your_windows_login_name
and that’s all. For your first connection, you will be asked to enter your AD password and probably to accept some security certificates. No further configuration needed. It should work out of the box.
If you try to reinitialize the root passwd of your Linux installation through a recovering boot with init=/bin/sh, you may have the following error message :
passwd: Authentication token manipulation error
First check if your / filesystem is mounted read-write or read-only. Restart your machine and at the Grub prompt (tested on a fresh install of RHEL 6.2 with Grub version of 0.97), change ro to rw as indicated below :
kernel /vmlinuz-2.6.32-220.el6-x86_64 ro root=/dev/mapper….
kernel /vmlinuz-2.6.32-220.el6-x86_64 rw root=/dev/mapper….
An other solution is to make sure that the content of /etc/passwd and /etc/shadow are the same with the pwconv command.
As root, before reinitializing again its passwd, run the command below :
You should have no more error message.
If you have a document in jpeg format and you want to print it in a more friendly printable format, let use convert from the ImageMagick utilities.
To install it :
root@localhost:~#apt-get install imagemagick imagemagick-doc
To make the conversion :
fool@localhost:~$ convert your_image.jpg your_image.pdf
Then you can open your new document with your pdf viewer.
Sometimes, this process can lead to a bigger file in size. Adding the following option -compress jpeg may help decrease this size :
fool@localhost:~$convert -compress jpeg your_image.jpg your_image.pdf
If you are planning to make more complex operations on pdf documents, have a look at the utilities provided by the pdfjam package.
