Dhcp & unknwon host

To fix the problem with unknown host using dhcp in Solaris 10, you need to edit 2 files:

1.) /etc/nodename. Add hostname to this file.
2.) /etc/default/dhcpagent. Edit this file and set this option: REQUEST_HOSTNAME=no

reboot and viola!

VIM: Slow to startup

Vim takes a long time to start.

Check your $DISPLAY variable is pointing to a valid X-Host.

smbclient 2 Windows 2003 server. Quicky

1.) Update smb.conf file: Global section.
# Global parameters
[global]
workgroup = DOMAIN-NT
security = DOMAIN
server string = Samba %v on %h - Wacky
max log size = 65536
preferred master = No
local master = No
domain master = No
wins server = 192.167.0.4, 192.168.0.6
password server = 192.168.0.4, 192.168.0.6
idmap uid = 20000-29999
idmap gid = 20000-29999
template homedir = /dev/null
winbind enum users = Yes
winbind enum groups = Yes

restrict anonymous = 2
syslog = 1

;client schannel = no
;winbind use default domain = Yes

msdfs proxy = no

2.) Join the domain.

/usr/local/samba/bin/net RPC join -U username
And then
/usr/local/samba/bin/net rpc testjoin

3.) Connect.

smbclient //server/share -U username%password -W DOMAIN-NT
Domain=[DOMAIN-NT] OS=[Windows Server 2003 3790] Server=[Windows Server 2003 5.2]
smb: \>

Done.
