To disable the visual bell for the current screen instance, hit:
CTRL+A, CTRL+G
For a permanent fix, put the following into the ~/.screenrc file
vbell_msg "bell: window ~%" # Message for visual bell vbellwait 2 # Seconds to pause the screen for visual bell vbell off # Turns visual bell off
While I was trying to add a virtual disk to a headless virtual machine, upon running
VBoxManage modifyvm MachineName --hda DiskName.vdithis error occurs:
ERROR: Could not find a storage controller named 'IDE Controller'This can be resolved by replacing
<StorageControllers /> with
<StorageControllers>
<StorageController name="IDE Controller" type="PIIX4" PortCount="2">
</StorageController>
</StorageControllers>
Actually, scratch everything above. Use the following tutorial: http://forums.virtualbox.org/viewtopic.php?f=7&t=28273
If Sendmail takes several minutes to start, and your PHP scripts hangs when attempting to send emails via sendmail (eg: using the mail() function), ensure that your hosts file has its host name as an alias to localhost.
For instance, your hosts file should look something like this:
[leo@crow ~]$ cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 109.169.59.122 crow
You would want to add your host name to 127.0.0.1:
[leo@crow ~]$ cat /etc/hosts 127.0.0.1 localhost.localdomain localhost crow 109.169.59.122 crow
Once that’s done, Sendmail should start and work normally.
