Re: [Vserver] vmware-player on host
are you sure you have successfully rebuilt your vmmon/vmnet modules? yep, I re-emerge vmware-player after patch the kernel with Linux-VServer patch. running vmware-config.pl doesn't resolve the problem. Are you sure everything works as planned there? I'm successfully running vmware server on a vserver-patched host. I needed the vmware any-to-any patch though, to get the vm* modules to compile (vmware are doing a really bad job at keeping up with kernel development ;) Tom ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

Re: [Vserver] vmware in vserver?
You might be spinning your wheels on that - many win-apps will detect vmware and refuse to run - even Windows virus applications will usually detect vmware and go into hiding. Going way off-topic here, but I've never ever had any windows app refuse to run because it was running inside a vmware instance.

I've made different scripts already to be able to monitor daemon stuff through cacti, and was planning on making on one side some nice graphs about load and memory and such, and otherwise an overview page with all the info on it.

Re: [Vserver] HOWTO deal with NAT'ing firewalls and source-based routing with vservers
given address
Then the source address of the packets are translated as it
should!
So forget about MASQUERADE. But now I hear you cry: But
then I have to
change the SNAT rule every time eth0 changes address!. No I
fixed that:
* Install ISC DHCP Client 3.x (on debian do: # apt-get
install
dhcp3-client).
* Download the tarball,
http://wheezy.homelinux.net/cgi-bin/viewcvs.cgi/dhclient-scripts.tar.gz?view=tar,
and install it (instructions are in the scripts).
Basically this packages provides a small perl script, which
is called by
the DHCP client, and it is setting a SNAT rule according to
the IP
address that the DHCP client got. It also removes the rule,
if the
interface is shutdown, and it updates the rule, if the
interface changes
address.
If you don't want to use ISC DHCP Client 3.x but for
instance ISC DHCP
Client 2.x, then you have to find a way to have the dhcp
client call
snatman.pl with the correct parameters.
Configuring the source-based routing automatically on
debian.
Add the entry to /etc/network/interfaces:
auto dummy0
iface dummy0 inet static
address 192.168.2.1
netmask 255.255.255.255
Make a script /etc/network/if-up.d/vserver containing:
#!/bin/sh
if [ $IFACE = dummy0 ]; then
if ! egrep --quiet \
--word-regexp \
vserver /etc/iproute2/rt_tables; then
echo You haven't created a vserver table \
in /etc/iproute2/rt_tables
echo Try adding a line like '100 vserver' \
to /etc/iproute2/rt_tables
exit 1
fi
if [ ${MODE} = start ]; then
ip rule add from 192.168.2.0/24 table vserver
ip route add default dev eth0 table vserver
ip route add 192.168.1.0/24 dev eth1 table vserver
fi
fi
and make /etc/network/if-up.d/vserver executable:
# chmod 0755 /etc/network/if-up.d/vserver
Also make the script /etc/network/if-down.d/vserver:
#!/bin/sh
if [ $IFACE = dummy0 ]; then
if ! egrep --quiet \
--word-regexp \
vserver /etc/iproute2/rt_tables; then
echo You haven't created a vserver table \
in /etc/iproute2/rt_tables
echo Try adding a line like '100 vserver' \
to /etc/iproute2/rt_tables
exit 1
fi
if [ ${MODE} = stop ]; then
ip route del default dev eth0 scope link table
vserver
ip route del 192.168.1.0/24 dev eth1 scope link
table vserver
ip rule del from 192.168.2.0/24 lookup vserver
fi
fi
and make it executable too:
# chmod 0755 /etc/network/if-down.d/vserver
Thats it.
thanks, good work!
best,

This reduces the problems of having to have staff on-site selecting the kernel at boot time. If it panics, we tell them to just hit the reset button and it'll come back up on the old kernel. ~From memory the option is the '-R' command line switch. (And typical, now I go look for it, it's on that Fedora machine!) Yep, -R. Very useful, particularly with the panic= kernel commandline option... e.g. panic=30 waits 30 seconds then reboots automatically.

[Vserver] Bugreport: Hang when starting vserver in the background
Hi, A few days ago I started a vserver with vserver name start, as I wanted to do other stuff while it was starting. However, it didn't come up... I then typed fg to see if it would then come up while in foreground, but it didn't... Terminal just sat there, ctrl-c also did nothing. As I was in a hurry I just rebooted the host machine (had to happen anyway). Sorry I dont have more information. :) Tom ___ Vserver mailing list [EMAIL PROTECTED] http://list.linux-vserver.org/mailman/listinfo/vserver
