CHANGELOG
|

=========
|
||||
|
||||
In Development
|
||||
--------------
|
||||
|
||||
Mail:
|
||||
|
||||
* Fixed a long-standing issue with training the spam filter not working (because of a file permissions issue).
|
||||
|
||||
Control panel:
|
||||
|
||||
* Munin system monitoring graphs are now zoomable.
|
||||
* When a reboot is required (due to Ubuntu security updates automatically installed), a Reboot Box button now appears.
|
||||
|
||||
Setup:
|
||||
|
||||
* A swap file is now created if system memory is less than 2GB, 5GB of free disk space is available, and if no swap file yet exists.
|
||||
* Setup dialogs did not appear correctly when connecting to SSH using Putty on Windows.
|
||||
* We now install Roundcube from our own mirror because Sourceforge's downloads experience frequent intermittant unavailability.

/usr/lib/munin/cgi/munin-cgi-graph is a perl cgi script in the munin package

headers based on parameters in the requesting URL. All output is written

to stdout which munin_cgi splits into response headers and binary response
|

data.

munin-cgi-graph reads environment variables as well as passed input to determine

querystring to be in the env-var QUERY_STRING as well as passed as input to the

munin-cgi-graph has several failure modes. Some write HTTP Status headers and

others return nonzero exit codes.

the cgi script behind mailinabox's auth mechanisms and avoids additional

# prevent for instance spam filtering from crashing
|

|

# and buffers for the system. We will only allocate this file if there is more
|
||||
# than 5GB of disk space available
|
||||
|
||||
# The following checks are performed:
|
||||
# - Check if swap is currently mountend by looking at /proc/swaps
|
||||
# - Check if the user intents to activate swap on next boot by checking fstab entries.
|
||||
# - Check if a swapfile already exists
|
||||
# - Check if the root file system is not btrfs, might be an incompatible version with
|
||||
# swapfiles. User should hanle it them selves.
|
||||
# - Check the memory requirements
|
||||
# - Check available diskspace
