edition of /etc/sysctl.conf

[Balbuzard]

Hi!

I have installed OpenVZ on Debian 5.0 Lenny and I am afraid having some trouble with an error-message which comes out during the reboot of the debian-computer;

Setting kernel variables /etc/sysctl.conf line net.ipv4.conf.eth1.proxy_arp=1 is an unknown key failed

I have followed the steps to install OpenVZ on Debian, except for this line, I have had to change eth0 to eth1 because the eth0 interface is broken.

I have not configured openvz now, could you please explain to me if this error-message will have consequences during the creation of the containers? And is there any way to fix it?

Thanks a lot for your answers!!

Do you see this error also when you run sysctl -p? What's the output of ifconfig?

[Balbuzard]

No, there is no error in the output of sysctl -p
Here is the output of ifconfig:

Maybe is's just a warning, and there is no real problem with it...
Thanks for your answer!!

EDIT:

I have created my first container, and setted it its IP address:

:~# vzctl start 101
Starting container ...
Container is mounted
Adding IP address(es): 192.168.0.101
arpsend: 192.168.0.101 is detected on another computer : 00:00:0c:07:ac:00
vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 192.168.0.101 eth1 FAILED
Setting CPU units: 1000

I don't understand the WARNING message, is there any link with the trouble I have had before?
Thanks for your help, falko!

Do you get the error also when you use net.ipv4.conf.eth0.proxy_arp=1 instead of net.ipv4.conf.eth1.proxy_arp=1?

[Balbuzard]

Yes, it's the same. I have not used the eth0 interface because there is a problem on it.
Thanks for your answer!

[falko]

What's in your /etc/sysctl.conf?

[Balbuzard]

Hi!
Here is my sysctl.conf file (I have not pasted all the comments)
Thanks again for your help! But maybe this error doesn't mean anything?

# Uncomment the next line to enable packet forwarding for IPv4
net.ipv4.ip_forward=1

# Uncomment the next line to enable packet forwarding for IPv6
#net.ipv6.conf.all.forwarding=1
#-- OpenVZ begin --#

# On Hardware Node we generally need
# packet forwarding enabled and proxy arp disabled
net.ipv4.conf.default.forwarding=1
net.ipv4.conf.default.proxy_arp = 0

# Enables source route verification
net.ipv4.conf.all.rp_filter = 1

# Enables the magic-sysrq key
kernel.sysrq = 1

# TCP Explict Congestion Notification
#net.ipv4.tcp_ecn = 0

# we do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects = 1

net.ipv4.conf.eth1.proxy_arp=1

#-- OpenVZ end --#

Looks ok. Not sure what the problem is... :(

[Balbuzard]

OK
I consider this trouble as solved, I have not had issues when building the internet connection between the containers or between internet and the containers, so maybe it's just a warning, even if it does not look like it.

Thank you for your help!
