My server is rx6600 and OS is HP-US 11.3. Server rebooted and after this IP configuration lost. No clients could connect.
I connected via iLO. During running net start got error:
# /sbin/init.d/net start
/sbin/init.d/net[135]: 1500: not found.
ERROR: Incorrect data in the file /etc/rc.config.d/netconf.
First i didnt know what is worng. After several researches found out that this parameter has wrong value in netconf file:
...
ROUTE_COUNT[0]=1
ROUTE_MASK[0]=
ROUTE_ARGS[0]=-p 1500
and i changed ROUTE_ARGS[0]= "-p 1500" then restart net start. Since put in quoted ROUTE_ARGS value everything works.
So question, for what is ROUTE_ARGS and what's differ between values -p -f and -n?
Where missed quoted then? i didnt changed netconf, so what could be the reason on changing netconf after reboot?
regards and thanks,
rustam

Re: incorrect netconf file
excerpt from netconf:
# ROUTE_ARGS: Route command arguments and options. This variable
# may contain a combination of the following arguments:
# "-f", "-n" and "-p pmtu".
'-p' is for setting the MTU for the given route. What others mean you can read in:
#man route

Re: incorrect netconf file
> ROUTE_ARGS[0]=-p 1500
...is illegal shell syntax. You must quote (using single or double quotes) any variable assignment that contains whitespace:
# ROUTE_ARGS[0]="-p 1500"
or:
# ROUTE_ARGS[0]='-p 1500'

Re: incorrect netconf file
But i dont know who\what could change MTU value. The ioscan result is:
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
lan 0 0/4/2/0 iether CLAIMED INTERFACE HP AB352-60003 PCI/PCI-X 1000Base-T Dual-port Core
lan 1 0/4/2/1 iether CLAIMED INTERFACE HP AB352-60003 PCI/PCI-X 1000Base-T Dual-port Core
lan 2 0/6/0/0/0/0/4/0/0/0 iether CLAIMED INTERFACE HP AD337-60001 PCIe 1000Base-T Dual-port Adapter
lan 3 0/6/0/0/0/0/4/0/0/1 iether CLAIMED INTERFACE HP AD337-60001 PCIe 1000Base-T Dual-port Adapter
I wasnt a long time in office, and 2 guys also had access. But they say we didnt change anything.

Re: incorrect netconf file
It would seem that someone must have changed the file.
You shouldn't need to use the -p MTU on the route anyway, Dynamic Path MTU Discovery is on by default .
And if you don't know why it was changed, and you're the admin, then I'd take it back out.
There could be times you'd need to change the pMTU, though. E.g, if the default route is the actual router to your ISP and is using ADSL or something, you might need to drop it to prevent framentation if the discovery is not getting an appropriate value.
## ndd -get /dev/ip ip_pmtu_strategy
1
1 means dynamic discovery is on
## netstat -rvn
last column will show the pMTU for all routes.

Re: incorrect netconf file
i didnt notice modification and remembered about after changed file. Does there any function\utilities which shows previous modification?
so you think that i have to change this parameter to default (zero)?

Re: incorrect netconf file
You didn't make the change.
Whoever/whatever made the change didn't make it correctly.
The change is not necessary.
So, yes, I'd remove the change:
just remove the "-p 1500" and leave it at:
ROUTE_ARGS[0]=
