Operating Systems Linux Unable to connect guest VM to internet (QEMU via both 'User-mode networking' and 'TUN/TAP') Post 302982076 by temp-usr on Friday 23rd of September 2016 07:53:19 AM

I installed Oracle VirtualBox v4.3.36 and only ticked "NAT Networks" which is default mode from:

File Menu -> Preferences -> Network

then installed FreeBSD on it and it can connected to internet without any problem, altough it has some limitation which of cource these limitations normally don't affect normal network use:
Thanks to SUN Microsystems and Oracle Corporation.

I changed "DNS nameserver" on FreeBSD from:

#bsdconfig
-> Networking Management -> DNS nameservers

and changed it from 127.0.0.1 to 10.0.2.3

problem solved! on VirtualBox I did not have to deal with this problem. I think this problem was created by me, because several times when my modem was turned off I configured ethernet interface on FreeBSD with enabling and disabling DHCP, I'm not sure, just likely.

NAME
bsdconfig -- system configuration utility SYNOPSIS
bsdconfig [-h] bsdconfig command [-h] bsdconfig [OPTIONS] [command [OPTIONS]] DESCRIPTION
bsdconfig is used to set up many system configuration settings, both for new systems, as well as changing configuration settings of existing systems. bsdconfig optionally takes a command as an argument. If invoked with no arguments, it will bring up an interactive menu listing the avail- able modules. The following options are available: -d Provide lots of debugging info on standard-out when running. -D file Send debugging info to file. If file begins with a plus-sign debug info is sent to both standard-out and file (minus the leading plus). -f file Load file as script and then exit. If multiple occurrences, program will only exit after last occurrence. If file is a single dash ('-'), bsdconfig reads from standard input. -h Print usage statement and exit. -S Secure X11 mode (implies -X). As root, always prompt-for and validate sudo(8) username/password before starting. -X Use Xdialog(1) in place of dialog(1). COMMANDS
The following commands (sorted alphabetically) are currently included in the base bsdconfig program, with more to be added soon. Other com- mands can be added, as detailed below in the ADDING COMMANDS section, and once added, will appear in the master menu as well as in the -h listing. console Utilities to customize the behavior of the system console. defaultrouter Shortcut to the Default Router/Gateway menu under networking. diskmgmt Manage disk partitions and/or labels.

INTERNATIONALIZATION
i18n features are built into bsdconfig and language-specific translation files will be added as they become available. In the absence of language-specific translation files, the default (en_US.ISO8859-1) files will be used. ADDING COMMANDS
To be documented later. Document menu_selection="command|*" syntax of INDEX files. ENVIRONMENT VARIABLES
The following environment variables affect the execution of bsdconfig: LANG If LANG is set, messages and index information will be read from files named messages.$LANG and INDEX.$LANG and fall back to files named messages and INDEX if messages.$LANG and INDEX.$LANG do not exist. LANG takes precedence over LC_ALL. LC_ALL If LC_ALL is set, messages and index information will be read from files named messages.$LC_ALL and INDEX.$LC_ALL and fall back to files named messages and INDEX if messages.$LC_ALL and INDEX.$LC_ALL do not exist. FILES
/usr/share/examples/bsdconfig/bsdconfigrc can be copied to $HOME/.bsdconfigrc and customized as needed. EXIT STATUS
The bsdconfig utility exits 0 on success, and >0 if an error occurs. SEE ALSO
bsdinstall(8) HISTORY
bsdconfig first appeared in FreeBSD 9.2. AUTHORS
Ron McDowell Devin Teske <dteske@FreeBSD.org> BUGS
The docsinstall and diskmgmt modules call bsdinstall. Bugs found in these modules should be considered those of bsdinstall, not bsdconfig. BSD
