Network

If you’ve setup samba (rather than the builtin cifs/smb) chances are that you can only browse to your samba shares directly on IP only.

If you want your box “network browseable” you’ll need to load nmbd.

You can find a really good write up on modifiying the SMF for samba to autostart the required service here : http://wikis.sun.com/display/BigAdmin/Enabling+Browsing+with+Samba+in+Solaris+10+Update+4

import this file samba.xml

run these commands;

# svcadm disable samba
# svccfg import samba.xml
# svccfg delete svc:/network/samba:default
# svcadm refresh samba:smbd
# svcadm refresh samba:nmbd
# svcadm enable samba:smbd
# svcadm enable samba:nmbd

If your keen on enabling jumbo frames in opensolaris this is the way…

I’ve had this with certain kernels (2009.06) on opensolaris. Seems there is some incompatibility between some kernels and the opensolaris virtualbox network emulation. This only seems to effect linux virtual guests.

When you try to ping an address you get something like this…

[root@VA-DHCPWEB ~]# ping 192.168.9.15 PING 192.168.9.15 (192.168.9.15) 56(84) bytes of data. 64 bytes from 192.168.9.15: icmp_seq=1 ttl=128 time=1.85 ms 64 bytes from 192.168.9.15: icmp_seq=1 ttl=127 time=1.88 ms (DUP!)

To show what routes your cisco router currently has loaded type the following command (from the enable prompt) ;

show ip route

To add any new static routes you need to use the following command (from the config terminal prompt) ;

ip route 10.10.20.0 255.255.255.0 192.168.100.1

the syntax as above is ip route network netmask gateway

Things you’ll need; (basic instructions) SSH - either Linux or Open SSH for windows (set this up first and ensure its working!). I have only used Linux, so i do not know the details of setting up a Open SSH box on windows (good luck).

Router with pinhole or port forwarding abilities. – forward your external 443 port to internal 22 on your SSH box

Putty.exe - use this to test your SSH connection locally (you should be able to connect on port 22 locally or 443 externally)

Setting up a trunk between switches

Enable Switch to enable mode Configure Terminal Enter global configuration mode

Interface FastEthernet0/1 Entering interface configuration for port 0/1. This is where you pick the port you want to trunk.

Switchport mode trunk Set port to trunking mode.

Switchport trunk encapsulation dot1q Set trunk type to 802.1q. If your switch only supports either ISL or 802.1q, this command does not exist because there is nothing to specify. This command only works when you can choose between the two.
