how to custom port mountd nfs ?

WorldIsNotFair · 07-29-2008, 04:38 AM

Hello brotha,

Need a hand,

How we can custom that ?

I noticed on fedora dist, we can custom it on /etc/sysconfig/nfs,

but i don't know how to do it on slackware.

Any Slackers, please help me ...

Thanks.

I think you have gotten no replies because you have not given enough information. What do you want to do? What do you mean by "custom", is it "customize"? I have never needed a file to customize nfs mounts. Explain a little more, please.

Bill

Ok Bill,

Thanks for replying.

Yes, i mean customize the port for port that related to nfs services so that we can config iptables rules more easy.

From what that i learn, these are the related port :
- portmap
- mountd
- statd
- nlockmgr
- rquotad

On redhat based distros, i change those port to 4002-4005 (except portmap).

There is an issues with iptables if the portmapper run dynamically, so i want to customize the related port.

If the other distros can do, i'm sure slackware can do it, i just can't figure it out.

Please help brotha.

Regards,

Heinz

Well, Heinz, now that I know what you want, I can't help you. I've never had to do that nor ever researched it, so I have no clue.
Sorry,

Well, take a look at the man page for mountd

man mountd

One of the options is the following:

Code:

-p  or  --port num
              Force rpc.mountd to bind to the specified port num, instead of using the  ran-
              dom port number assigned by the portmapper.

That's a capital P by the way ...

Now, what to do with that. Looking at /etc/rc.d/rc.nfsd you can see the following section:

Code:

if [ -x /usr/sbin/rpc.mountd ]; then
    echo "  /usr/sbin/rpc.mountd"
    /usr/sbin/rpc.mountd
fi

This might be a good place to use the -P option. Something like:

Code:

if [ -x /usr/sbin/rpc.mountd ]; then
    echo "  /usr/sbin/rpc.mountd"
    /usr/sbin/rpc.mountd -P <fixed port#>
fi

Total guess here. Never done it myself.

Another option might be in install webmin which may allow easier manipulation of this and other parameters. get the SlackBuild slackbuilds.org.

This is covered in some detail in the Slack Wiki here :

Thanks to our benefactor Robby Workman. This should get you going.

Thanks for all replies bro.

I had tested it and it works except for nlockmgr.

Showmount and rpcinfo is working.

I will continue to use slack for my desktop, thanks to you all, really appreciated.

Regards,

Heinz

From the link I posted - credit again to R.Workman..

Quote:

Finally, make the lock daemon listen on port 4045 only - note that this requires
setting module load options in a file in /etc/modprobe.d/ - I create an aptly
named file of /etc/modprobe.d/lockd and add the following:

options lockd nlm_udpport=4045 nlm_tcpport=4045

This seems relevant to the nlockmgr ports.

WorldIsNotFair · 08-02-2008, 02:54 AM

thanks bgeddy, but i already tried it, doesn't work.

should i supposed to activate some modules and recompile kernel for that ?

coz i don't know any modules related to this and i believe that i'm not running nfsd as module.

hey, on belowed page from his wiki, he said bout irc channel, do u know what channel ?

Regards,

Heinz

Are you running the installed "huge" kernel ? If so this won't work. It is recommended to switch to the generic kernel anyway after installation. From the CHANGES_AND_HINTS on the install media :

Quote:

Use one of the provided generic kernels for daily use. Do not report
bugs until/unless you have reproduced them using one of the stock
generic kernels. You will need to create an initrd in order to boot
the generic kernels - see /boot/README.initrd for instructions.

This will load lockd as a module and then the /etc/modprobe.d/lockd will take effect.

You don't need to recompile your kernel for this.

Robby Workman frequents the ##slackware irc channel so I suppose this is the one he's referring to.

Thanks bgeddy,

I install smp generic kernel + kernel modules, its work,

But my battery power meter dissapeared now .. lol ...

Thanks for you all.

bgeddy · 08-03-2008, 07:13 PM

Glad to see it works - but - if you are having difficulties with the power meter perhaps you might want to start a different thread here for help ?

I'm sure the Slackware folks will respond.

WorldIsNotFair · 08-03-2008, 10:33 PM

I had edit the kernel conf and recompile it, no issue now bro.

Thanks, you're very nice.

For the record, all you had to do to enable the battery power meter was uncomment/add a line in /etc/rc.d/rc.modules-$(uname -r) that loads the proper module. For example, this line in /etc/rc.d/rc.modules-2.6.24.5-smp:

Code:

# Battery (adds battery information through/proc/acpi/battery):
#/sbin/modprobe battery

WorldIsNotFair · 08-05-2008, 03:28 AM

Great info,

i'm still using 2.6.21.5-smp , i can't find battery modules on /lib/modules/$(uname -r), when i run modprobe, module not found.

is it only applied to 2.6.24.5-smp?

Thanks T3slider.
