Start up routines

[Loonygirl]

I'm running Tru64 Unix. My network is running at 100 MPS half duplex, the box itself is running at 10 half, which is causing severe clashes.

I can change the speed of the tru64 box using lan_config. However the network needs to be rebooted before the changes take effect (I think...please correct me if I'm wrong!!). My GUI had crashed, so I decided to restart the whole server. Checking the messages file, I saw that auto negotiation was off, and the box was forced to run at 10 half. This is obviously written into a start up routine somewhere....I'm totally new to Unix. Where do I look to find the file which specifies these settings??

I also need to add a couple of settings into this file - one is to add a default gateway (otherwise I have to add it manually everytime I start the box up, and I keep forgetting to!!!!). Can I just add "route add default 192.168.44.1" to the file as is??

Thanks,

Sarah

Hopefully man rc will give you some info on startup routines.

Hope This Helps, PH.

Hi Sarah,

It would help if you could post what the hardware is. Assuming it is an Alpha, then the Ethernet speed setting is done at the chevrons (>>> ). If you have a DE500 Ethernet adapter (like our systems), then use:
>>> set ewa0_mode twisted-pair (for 10mBit
>>> set ewa0_mode fast (for 100mBit

I can post further examples and explanations later if your hardware is similar to ours.

If you want to check the current setting try:
consvar -g ewa0_mode

To add a default gateway, edit the file /etc/routes and add the line (NB no leading spaces):
default <gateway-ip-address>


I hope that helps you.

Mike

Hi,

man rc doesn't work??

Forgive me for being very dumb here!!
when I do cat /etc/routes, I'm just dropped back to the # prompt. This is (I assume) because the file itself is empty?

#cat /etc/routes
#

If I vi and add the line
default 192.168.44.1

everything should be happy??

ewa0_mode isn't found.

Hardware: the only thing I can tell you is out of my messages file:

tu0: DEC TULIP (10/100) Ethernet Interface
tu0: autonegotiation off: selecting 10BaseT (UTP)port: half duplex

This always comes up when the server is rebooted, no matter what I set the setting to before I reset, therefore it must be stored somewhere?


Thanks for the advice so far!!

Does Tru64 support /etc/defaultrouter?

 

[KenCunningham]

Answer: No. Should have read Mike's post in more detail!!

 

[Loonygirl]

Hi Ken,

No.../etc/defaultrouter does not exist in my version of Tru64.

Incidentally....I forgot to post all the info on the hardware itself:

man rc doesn't work??

well, in Tru64, it's
man rc3

and see also: man rc2, man rc0

 

[Loonygirl]

well, in Tru64, it's
man rc3

and see also: man rc2, man rc0

Thanks )

Was following stuff through via S11gateway -> /sbin/rc3.d
which appeared to be a whole load of C code....
One of the variables NEWGATED pointed towards /usr/sbin/gated, but this file is a load of jargon.

I'm not a programmer....am I meant to be editing this code? Because going by the code which I normally produce, this would not be a good idea ;o)

Sarah

 

[hoinz]

Sarah,

no, /sbin/rc3.d/S11gateway is not C code; it's a shell script.
And no, I would not suggest that you edit this code.

But one way to overcome the problems you described in your initial post would be this:
Put all those commands you now have to enter manually after booting in a file, and make sure that this file is executed when booting.
To achieve this, you may call this file /sbin/rc3.d/S99mysettings.

This should work, but nevertheless there should be a way to change your config files, so that this additional work will not be necessary.

regards

Hi hoinz,

Thanks for the help!

I have an S99 already, so I assume I can use any number as long as it isn't taken.

If I use this file:

route add default 192.168.44.1
lan_config -i tu0 -s100

and save as /sbin/rc3.d/298mysettings

This will all happen at boot up and everything should be ok?

I'm still interested as to where the computer is picking up the settings for the network speed from - I'm surprised that auto-negotitation has been turned off - so if anyone has any ideas, please let me know!!

Thanks,

Sarah

 

[hoinz]

and save as /sbin/rc3.d/298mysettings

shouldn't this be
/sbin/rc3.d/S98mysettings
?

 

[Loonygirl]

Um....yes....maybe!

So, the above should be ok if I add it? (I'm bound to add something silly otherwise which sends the box into an infinite loop !)

Thanks,

Sarah

 

[hoinz]

yes
(and don't forget chmod to make the file executable)

 

[Loonygirl]

chmod /sbin/rc3.d/S98mysettings 999

Sarah

 

[hoinz]

no,
chmod 755 sbin/rc3.d/S98mysettings
man chmod

 

[KenCunningham]

...and there's no reason you shouldn't use S99 again, if there are two S99's the one first alphabetically will be executed first, followed by the second. However, S98 will do as well, don't want to muddy the waters further!! Good luck.

 

[Loonygirl]

hoinz,

yes, I looked at the manual and got it to be executable with a different set of commands

In future I will always read the manual before posting dodgy commands!!

Ken - thanks, that's good to know in the future!
Is S99 the highest that you can go? Or is it possible to have S100 etc?

Sarah

 

[KenCunningham]

Sarah, glad to help. S99 is the highest you should go to as the names are (as far as I know) ordered in ASCII character value, therefore 100 would actually some before 99 in these terms. As an aside, the S indicates Start me at boot up, while a K before a script in /etc/rc? indicates Kill me at shutdown. Replacing S or K with a lower case version essentially deactivates the script at startup/shutdown.

 

[Loonygirl]

Ah right, thanks.
I knew S was start up and K was shutting down, but I couldn't work out what the K actually stood for

Cheers for all your help everyone.
Server will be rebooted over the weekend, so we'll see whether my changes have produced the correct effect or not!!
