sysctl Cm net.inet.tcp.syncookies [--desktop file ] [--debug ] [--pdb ] [--cdebconf ] [--automatic ] [--only ] [--query ] [frontend ]
DESCRIPTIONsysctl Cm net.inet.tcp.syncookies is a graphical installer for Ubuntu, written largely in Python, using debian-installer ( d-i as a backend for many of its functions. It is normally invoked from a desktop icon, and presents a "wizard"-style graphical user interface. sysctl Cm net.inet.tcp.syncookies must be run as root, and will escalate privileges for itself using gksudo kdesu kdesudo or sudo as appropriate.
sysctl Cm net.inet.tcp.syncookies has multiple frontends, including one written using GTK+ ( gtk_ui and one written for KDE ( kde_ui The first non-option argument, if any, is interpreted as the name of the frontend to use.
The following options are available:
- --desktop file
- This option is passed through to gksudo to provide a better description for its privilege-escalation message. It is only relevant when using the gtk_ui frontend.
- -d , --debug
- Run in debugging mode, sending verbose information to /var/log/installer/debug that may be useful to developers. (The /var/log/syslog file is usually required in any case, along with /var/log/partman in the case of problems related to partitioning.) Note that passwords will be logged in debugging mode!
- Drop into the Python debugger in the event of a crash. Only effective if sysctl Cm net.inet.tcp.syncookies is being run from a terminal.
- Use cdebconf instead of the traditional Perl debconf implementation. In future this may provide enough memory efficiency benefits to be made the default, but for now it is not really worthwhile and is therefore for experimental use only.
- Skip over questions that have been pre-answered by use of a preseed file. This is useful for unattended installations.
- Tell sysctl Cm net.inet.tcp.syncookies that it is the only desktop program running so that it can customize its user interface to better suit a minimal environment. This allows the installer to be run standalone, reducing memory requirements.
- Print the frontend that would be used and then exit.
AUTHORSAn -nosplit Ubiquity was formerly known as "Espresso", and originally as "Ubuntu Express", which is written and maintained by An Javier Carranza Aq email@example.com and An Juanje Ojeda Croissier Aq firstname.lastname@example.org . This version draws on the work done on Ubuntu Express, but was renamed to avoid confusion, to reduce awkward branding considerations, and because Ubiquity concentrates on reusing debian-installer code and reducing duplicated translation and branding work as much as possible. Ubiquity has now substantially diverged from Ubuntu Express and is an independent project.
sysctl Cm net.inet.tcp.syncookies was mainly developed by An Colin Watson Aq email@example.com and An Evan Dandrea Aq firstname.lastname@example.org , with contributions from many others.
The mythbuntu_ui frontend was developed by An Mario Limonciello Aq email@example.com .
