Getting Started with Linux 1 (VM virtual machine install openSUSE 11,SECURECRT remote connection)

Linux version:

Opensuse-11.0-gnome-livecd-i386.torrent, (680M): http://ftp5.gwdg.de/pub/opensuse/discontinued/distribution/11.0 /iso/torrent/

Installation is the default, set the size of the hard disk is 8G, memory 1G, network connection Bridge, partition mount is a quick installation of the default, without modification.

After installation, ifconfig view SuSE's IP as 192.168.1.103, while the Physical Machine (notebook) is 192.168.1.100, from which the physical machine can ping through SuSE, while the SuSE side PING-C4 192.168.1.100 cannot ping the physical machine ...

　　Workaround: Shut down the physical machine's firewall.

SECURECRT connection SuSE Tip "Not connected" issue

1. No OpenSSH installed (ubuntu not installed )

2, does not start the SSHD service ( can netstat-antp command view )

3, the firewall is not open

Use the netstat command to see that the sshd service is already in the state of the boot, so only the firewall is not open for the sake of

　　

How to open a firewall reference: http://blog.csdn.net/aaronychen/article/details/2802199

Open this file:/etc/sysconfig/susefirewall2, the internal part of the file is as follows:

　　

Use the command:rcSuSEfirewall2 Restart //Restart the firewall for the configuration to take effect

　　

Boot defaults to file interface

Modify the default boot level in the/etc/inittab file
