Can not set default gateway to lan2

[mura-kei7]

There are 2 lan interfaces on a itanium HP-UX, lan0 is closed local address and lan1 must be reach another segment address. I defined routing data as default gateway for lan1's gateway address on this HP-UX server by sam, but sum abort by segmentation fault?

So , I wrote routing data directly in /etc/rc.config.d/netconf  and type command " route add default gw xx.xx.xx.xx".

(xx.xx.xx.xx is lan1's gateway address)

1. Please tell me why sam failed?

2. Can lan1's(not lan0) gateway works default gateway on this HP-UX?

Hi,

Could you please show me the output

#netstat -rn

Thanks

Shalom,

It is certainly possible to use lan2 and set its gateway to lan2.

To really assist you, I'd need to see relevant portions of /etc/rc.config.d/netconf and your routing tables.

netstat -rn

Hi,

I just assume what are you trying to do and hope it would help you to overcome this.

Below i provide the step and hope this could help you

Files need to be configure:

• /etc/hosts - Hosts configuration file (resolve hosts and IPs)
• /etc/rc.config.d/netconf – IP address, routeing address and hostname stored in this file

Scripts for network:

• /etc/init.d/net start – Use to start, stop network service

Misc command related network could help you
# lanscan

 All in one lan configuration utility (lan0 is first Ethernet interface) to configure and view the system IP address:

# ifconfig lan0 - Display IP info such as IP address netmask etc.

# ifconfig lan0 up - Up network interface (allow traffic)
# ifconfig lan0 down - Down network interactive (deny traffc)
# ifconfig lan0 x.x.x.x netmask x.x.x.x up - Setup/change IP adddress

Display routing table/info:
# netstat -nr

Define new route:
# route add default 192.168.1.254 1

HP's LAN diagnostic tool
# lanadmin

Setup various lan properties, dns client, NIS client configuration etc using GUI tool:
# sam
# set_parms

Thanks

Thank you for your advice,

I'm sorry, lan1 of my first post is spell miss of lan2 .

Unfortunately I can NOT copy  all files on the hp-ux server to outside, because security of the customer's policy.

So I write some file's information on this reply.

When I got sam's error, hosts and netconf files was defined bellows.

------

1. /etc/hosts

   define lan0's address -> lan2's address

   192.168.0.10 xxx

   192.142.1.11 xxx     <- defined same name

2. /etc/rc.config.d/netconf

....

INTERFACE_NAME[0]="lan0"
IP_ADDRESS[0]="192.168.0.10"
SUBNET_MASK[0]="255.255.255.0"
BROADCAST_ADDRESS[0]=""
INTERFACE_STATE[0]=""
DHCP_ENABLE[0]=0
INTERFACE_MODULES[0]=""

...

routing data are default. (all lines were comment outed)

...

DEFAULT_INTERFACE_MODULES=""
IP_ADDRESS[2]=193.42.1.11
SUBNET_MASK[2]=255.255.255.0
INTERFACE_NAME[2]=lan2
BROADCAST_ADDRESS[2]=193.42.1.255
INTERFACE_STATE[2]=up

-------

and I tried to add routing information 193.42.1.254 by sam "Add Default Route..." menu.

When I pushed apply button, sam showed me core dumped message,

and routing info on /etc/rc.config.d/netconf  was not changed.

I forgot netstat -nr's output , but folowing output was returned, mabe.

No gateway setting found.

---

destination   Gateway 

193.42.1.11  19342.1.11

193.42.1.0  19342.1.11

I could defined lan2's routing address as default gateway by direct modification of /etc/rc.config.d/netconf.

ROUTE_DESTINATION[2]=default
ROUTE_MASK[2]="255.255.255.0"
ROUTE_GATEWAY[2]="193.42.1.254"
ROUTE_COUNT[2]="1"
# ROUTE_ARGS[2]=""

# netstat -nr's output are

default 193.42.1.254 UG 0 lan2

So this machine could reach outside server of gateway 193.42.1.254.

Thank you for all messages.
