= GEC 9 Demo AP / Client Node Image = {{{ Ubuntu Version: 10.04 Current Image Name: ssugrim-node-1-7-2010-09-22-20-04-54.ndz }}} Installed software from Baseline Should Include: * HostAPD - Apt Package * Netsnmp - 2 Apt packages * !OpenVswitch - Downloaded from http://openvswitch.org/releases/openvswitch-1.1.0pre1.tar.gz [[BR]]Additional Packages Required: * libssl-dev * pkg-configure (complains SSL is not found if this is not installed) * ''Optional'' python-json * ''Optional'' python-qt4 * ''Optional'' python-zopeinterface * ''Optional'' python-twisted-conch * ''!MadWifi'' - was requested but omitted, I think they just need generic Wireless drivers. Ath5k drivers are installed by default. modprobe ath5k enumerates the devices. * VLC - Apt package * Wimax driver. * Free-nx ---- === Notes === It makes more sense to have a single image with all the necessary components that can change behavior based on scripts. To that end I've merged all the requirements. === 9/10 === Talked with KK, we'll need to iron out the verion of the kernel we're going to use. Currently I'm missing a few tools/package: NX, vlc, snmp, and snmpd === 9/17/2010 === Starting over with 10.04. We've decided we want the Image to be based of ubuntu 10.04 so that our wimax drivers will work with it. We may have to update date the kernel version. So far I have: * hostapd * snmp * snmpd * libssl-dev * build-essential * vlc * freenx - Installed by following instructions from https://help.ubuntu.com/community/FreeNX '''THIS FAILED MISERABLY''' I had to modify the sources back to their original settings cuz they were a giant mess. FreeNx failed to install and the instruction are buggy at best. The packages claim to be broken. They may have to live with VNC which we know works. If we're scripting, why do we need a remote viewer at all? Apparently the following packages don't exist in the repository (this could be due to my sources being messed up. * pkg-configure (complains SSL is not found if this is not installed) * python-json * python-qt4 --- === 10/22/2010 === Starting over yet again, dues to some package corruption bugs. I've changed the source file to source directly from mit meadia labs for the time being to get past some issues. After an update I installed the main stay of packages. {{{ apt-get install hostapd snmp snmpd build-essential libssl-dev pkg-config }}} I'll also need kernel headers for moudle support. {{{ sudo apt-get install linux-headers-$(uname -r) }}} With that stuff setup I'm going to Install OpenVswitch with kernel module support. {{{ ./configure --with-l26=/lib/modules/`uname -r`/build }}} I'm including a copy of config.log for refrence. I ran the usual, make, make install combo. Once run the ovs-* tools should be accessible. From here I simply need to insert the module and see if I can make a virtual switch. Create some virtual interfaces, and add them to the virtual switch. {{{ root@node1-7:/opt/openvswitch-1.1.0pre2# insmod datapath/linux-2.6/openvswitch_mod.ko root@node1-7:/opt/openvswitch-1.1.0pre2# lsmod Module Size Used by openvswitch_mod 61272 0 root@node1-7:/opt/openvswitch-1.1.0pre2# ip link add type veth root@node1-7:/opt/openvswitch-1.1.0pre2# ovs-dpctl add-dp dp0 root@node1-7:/opt/openvswitch-1.1.0pre2# ovs-dpctl add-if dp0 veth0 root@node1-7:/opt/openvswitch-1.1.0pre2# ovs-dpctl show system@dp0: flows: cur:0, soft-max:1024, hard-max:1048576 ports: cur:2, max:1024 groups: max:16 lookups: frags:0, hit:0, missed:0, lost:0 queues: max-miss:100, max-action:100 port 0: dp0 (internal) port 1: veth0 }}} We can verify all the drivers and modules are working with ifconfig. {{{ root@node1-7:/opt/openvswitch-1.1.0pre2# ifconfig -a dp0 Link encap:Ethernet HWaddr 00:23:20:88:f5:b8 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) eth0 Link encap:Ethernet HWaddr 00:0f:ea:4a:8a:fe BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:11 eth1 Link encap:Ethernet HWaddr 00:0f:ea:4a:8a:ff inet addr:10.40.1.7 Bcast:10.40.255.255 Mask:255.255.0.0 inet6 addr: fe80::20f:eaff:fe4a:8aff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:89811 errors:0 dropped:0 overruns:2 frame:0 TX packets:6729 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:68247118 (68.2 MB) TX bytes:1171359 (1.1 MB) Interrupt:10 eth2 Link encap:Ethernet HWaddr 00:0e:35:9e:52:e6 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:7 Base address:0xa000 Memory:eb018000-eb018fff lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) veth0 Link encap:Ethernet HWaddr b2:13:3e:6a:16:bc UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) veth1 Link encap:Ethernet HWaddr a2:da:ae:0c:31:c9 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) wlan0 Link encap:Ethernet HWaddr 00:60:b3:ac:a1:ce BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) }}} Finally We can start the openflow client in deamon mode with: {{{ root@node1-7:/opt/openvswitch-1.1.0pre2# ovs-openflowd dp0 tcp:10.50.0.13 --out-of-band --detach Sep 22 19:56:05|00001|openflowd|INFO|Open vSwitch version 1.1.0pre2 Sep 22 19:56:05|00002|openflowd|INFO|OpenFlow protocol version 0x01 Sep 22 19:56:05|00003|ofproto|INFO|using datapath ID 000000232080fc2d Sep 22 19:56:05|00004|rconn|INFO|dp0<->tcp:10.50.0.13: connecting... }}}
