How to setup Terminal Server on linux(OpenSUSE) for Dynamips

My dynamips was running on Window XP before it migrated to OpenSUSE. Since I used GNS3
on OpenSUSE, I didn't need to setup Terminal Sever. However, current work environment is not
flexible with GUI, so I tried to setup Terminal Server on linux(OpenSUSE) for Dynamips. It was
that hard to find tips and information thru web. Here is a shortcut to make it happens.
How to setup Terminal Server on linux(OpenSUSE) for Dynamips
1. Add "f0/0 - NIO_tap:tap0" on your Dynamips file. in this case
"TerminalServer-linux.net"
autostart = False
[localhost:7200]
workingdir = /home/Dynamips/lab/TerminalServer-linux.net
udp = 10000
[[3660]]
image = /home/Dynamips/ios/C3660-JK.extracted.bin
idlepc = 0x605f0ccc
ghostios = True
sparsemem = True
mmap = false
chassis = 3660
[[ROUTER TermServ]]
model = 3660
console = 2000
cnfg = /home/Dynamips/lab/TerminalServer-linux.net/TerminalServer-linux.cfg
f0/0 = nio_tap:tap0

2. Login your OpenSUSE system as root, or change privilege to sudo
OpenSUSE:/etc/sysconfig/network # sudo -i
Have a lot of fun...
Directory: /root
Sat Nov 14 21:07:08 EST 2009
OpenSUSE:~ #
3. Create a file "ifcfg-tap0" under /etc/sysconfig/network/ and reboot the
system.
/etc/sysconfig/network/ifcfg-tap0
BOOTPROTO='static'
STARTMODE='onboot'
IPADDR='10.10.10.1/24'
TUNNEL='tap'
TUNNEL_SET_GROUP=''
TUNNEL_SET_OWNER=''
TUNNEL_SET_PERSISTENT='yes'
OpenSUSE:~ # ping 10.10.10.1 ; after reboot the system.
OpenSUSE:~ #
4. Run "TerminalServer-linux.net" thru Dynamips and telnet in the the
Termserv(in this case Cisco3660 router is used, b/c it take small memory
)
