mercurial abort: error: Name or service not known abort: error: Name or service not known abort: error: Name or service not known

Q: when cloning a mercurial repository, if you are getting error

"abort: error: Name or service not known"

If you are behind a proxy please make sure /etc/mercurial/hgrc or ~/.hgrc has correct proxy settings.
Mercurial also uses ENV variable http_proxy if set. you can set http_proxy variable in unix using


where is the host and 8080 is the port.

This error can also happen if you were behind proxy before and now you are not.

So to unset proxy setting for mercurial make sure in
you had commented out those lines

also clear the http_proxy ENV

you can use unset command for this

unset http_proxy

apache htacess directory listing

Apache allows to disable directory listing using htacess files.

By default in ubuntu apache document root directory is /var/www

you can edit configuration file located at /etc/apache2/sites-enabled/000-default

You have a folder called "private" in /var/www/private which contains some information. If your system is connected to internet and have public access anyone can get data from !!

To disable directory listing try this:

create a file called .htaccess in /var/www/private
set your favourite editor

sudo $EDITOR .htaccess

Options -Indexes                #disable directory listing on current directory
Options All -Indexes          #disable directory listing recursively

LSIViewer - The Free online Geospatial Data Viewer

LSI viewer (Libre Spatial Information Viewer) [1] was developed for users who may not have access to a suite of GIS software tools but would like to just view/display and print/export the data they have.
LSIViewer is an Online Spatial Map Viewer for your Local Data including Map Styling. Basic Styling includes changing background color, pen color, fill color, label color, label size, pen width.  It allows to view Attribute Table and export the current map view with styling to a SVG/JPEG/PNG files. Currently it can be used as a Map Viewer for Shapefile (.shp) format data. Other data formats are planned to be supported in later versions.  LSIViewer doesnt depends on MapServer, Geoserver.
You can start a discussion, report bugs, give feedback on our redmine instance[2].
