Hello everyone I am having problems with using LVS in Gentoo, I needed the
following modules built into the kernel:
ip_vs
ip_vs_rr
ip_vs_wrr
ip_vs_lc
ip_vs_wlc
ip_vs_lblc
ip_vs_lblcr
ip_vs_dh
ip_vs_sh
ip_vs_sed
ip_vs_nq
ip_vs_ftp


How I recompile the kernel is select the module that I need

<M> IP virtual server support
>>             -> [*] TCP load balancing
>>             -> [*] UDP load balancing
>>
> then do a make followed by a make modules_install.

ip_vs is in my list of modules (the only ip_vs*) and does not return an
error when I modprobe it but these are not there:

#lvs
ip_vs
ip_vs_rr
ip_vs_wrr
ip_vs_lc
ip_vs_wlc
ip_vs_lblc
ip_vs_lblcr
ip_vs_dh
ip_vs_sh
ip_vs_sed
ip_vs_nq
ip_vs_ftp


I am using kernel 2.6.30r5

Thanks for you Help,
Ninus.

Hi,

First, you got two requests in the other thread you post about LVS, one from
Albert Hopkins who told you to do a find /lib/modules/$(uname -r) -name
ip_vs*.ko, another ask from walt who told you to do manually a depmod, and it
seems that you ignored these advices.

So, did you ran theses commands and saw what happens after ?

Then if they don't works, please post more information about your problem, for
example, your full kernel .config ?

And then, *very* important point, please do not make double or triple posting,
it's very disturbing, and you will not get an answer quicker in this way.

Thanks a lot for your understanding.

Hey Xavier,

I do appologize for the two messages, it will not happen again. When issuing
a "find /lib/modules/`uname -r` -name ip_vs*.ko" I see only

"/lib/modules/2.6.30-gentoo- r6/kernel/net/netfilter/ip_vs.ko"

I do not see the rest

#lvs
ip_vs
ip_vs_rr
ip_vs_wrr
ip_vs_lc
ip_vs_wlc
ip_vs_lblc
ip_vs_lblcr
ip_vs_dh
ip_vs_sh
ip_vs_sed
ip_vs_nq
ip_vs_ftp

I build the kernel via:

make menuconfig
make
make modules_install
cp arch/... /boot/...

I did issue a depmod and still just:

/lib/modules/2.6.30-gentoo-r6/kernel/net/netfilter/ip_vs.ko"

when issuing a "find /lib/modules/`uname -r` -name ip_vs*.ko"


Thanks in Advanced,
Ninus

Ok so, under Networking support -> Networking options -> Network packet
filtering support (Netfilter), you enabled <M> IP virtual server support, then,
under <M> IP virtual server support, you said earlier that you enabled :

  [*]   TCP load balancing support

  [*]   UDP load balancing support

but, you're looking for ip_vs_* modules, so it seems you did not enabled theses
items :

        *** IPVS scheduler ***
  <M>   round-robin scheduling (which is ip_vs_rr.ko)
  <M>   weighted round-robin scheduling (which is ip_vs_wrr.ko)
  <M>   least-connection scheduling (which is ip_vs_lc.ko)
  <M>   weighted least-connection scheduling (which is ip_vs_wlc.ko)
  <M>   locality-based least-connection scheduling (which is ip_vs_lblc.ko)
  <M>   locality-based least-connection with replication scheduling (which is
ip_vs_lblcr.ko)
  <M>   destination hashing scheduling (which is ip_vs_dh.ko)
  <M>   source hashing scheduling (which is ip_vs_sh.ko)
  <M>   shortest expected delay scheduling (which is ip_vs_sed.ko)
  <M>   never queue scheduling (which is ip_vs_nq.ko)
        *** IPVS application helper ***
  <M>   FTP protocol helper (which is ip_vs_ftp.ko)

did you ? And, yes, next time you are looking for something in the kernel
config, please do a search using menuconfig (simply issue make menuconfig in the
kernel tree, and when the menu shows up, then use the '/' key, and enter the
<name> of the CONFIG_ item you're looking for)

HTH.
