Hi guys,
I'm running Solars 8 on a V100 server at home for testing.
If I switch user to root and do:
# echo $PATH
This is the output:
/usr/sbin:/usr/bin
I'm using rsync over ssh and need to add /usr/local/bin and /user/local/sbin.
I do this by running the line:

hi,
I am trying to configure one of my interfaces, but after reboot - i lose the changes to the netmask & broadcast address.
I have added an entry in /etc/netmasks, but it doesnt pick up the new settings. any ideas - much appreciated.

how do I make sure that the entry in the routing table on Solaris 8 stay permanent after rebooting the server.
For example
route add 172.20.1.60 -netmask 255.255.255.0 172.20.255.253
Each time the server reboots the entry disappears when using the command netstat -nr (2 Replies)

Hi
If suppose there is a MAC address of NIC port. I have change the MAC address through following command

GRE(4) BSD Kernel Interfaces Manual GRE(4)NAME
gre -- encapsulating network device
SYNOPSIS
To compile the driver into the kernel, place the following line in the kernel configuration file:
device gre
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_gre_load="YES"
DESCRIPTION
The gre network interface pseudo device encapsulates datagrams into IP. These encapsulated datagrams are routed to a destination host, where
they are decapsulated and further routed to their final destination. The ``tunnel'' appears to the inner datagrams as one hop.
gre interfaces are dynamically created and destroyed with the ifconfig(8) create and destroy subcommands.
This driver corresponds to RFC 2784. Encapsulated datagrams are prepended an outer datagram and a GRE header. The GRE header specifies the
type of the encapsulated datagram and thus allows for tunneling other protocols than IP. GRE mode is also the default tunnel mode on Cisco
routers. gre also supports Cisco WCCP protocol, both version 1 and version 2.
The gre interfaces support a number of additional parameters to the ifconfig(8):
grekey Set the GRE key used for outgoing packets. A value of 0 disables the key option.
enable_csum Enables checksum calculation for outgoing packets.
enable_seq Enables use of sequence number field in the GRE header for outgoing packets.
EXAMPLES
192.168.1.* --- Router A -------tunnel-------- Router B --- 192.168.2.*
/
/
+------ the Internet ------+
Assuming router A has the (external) IP address A and the internal address 192.168.1.1, while router B has external address B and internal
address 192.168.2.1, the following commands will configure the tunnel:
On router A:
ifconfig greN create
ifconfig greN inet 192.168.1.1 192.168.2.1
ifconfig greN inet tunnel A B
route add -net 192.168.2 -netmask 255.255.255.0 192.168.2.1
On router B:
ifconfig greN create
ifconfig greN inet 192.168.2.1 192.168.1.1
ifconfig greN inet tunnel B A
route add -net 192.168.1 -netmask 255.255.255.0 192.168.1.1
NOTES
The MTU of gre interfaces is set to 1476 by default, to match the value used by Cisco routers. This may not be an optimal value, depending
on the link between the two tunnel endpoints. It can be adjusted via ifconfig(8).
For correct operation, the gre device needs a route to the decapsulating host that does not run over the tunnel, as this would be a loop.
The kernel must be set to forward datagrams by setting the net.inet.ip.forwarding sysctl(8) variable to non-zero.

A description of GRE encapsulation can be found in RFC 2784 and RFC 2890.

BUGS
The current implementation uses the key only for outgoing packets. Incoming packets with a different key or without a key will be treated as
if they would belong to this interface.
The sequence number field also used only for outgoing packets.
