ubuntu - LXC networking with public IP

I have installed LXC in ubuntu server 12.04 using this link. It was installed successfully and i am able login using ubutu/ubuntu as username and password. Then I tried to setup network for LXC container.



I changed in /etc/network/interface as




auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 125.67.43.100
netmask 255.255.255.0
broadcast 178.33.40.255
gateway 125.67.43.1



Content of /var/lib/lxc/mycontainer/config is:



lxc.utsname = mycontainer
lxc.mount = /var/lib/lxc/test/fstab
lxc.rootfs = /var/lib/lxc/test/rootfs


lxc.network.type = veth

lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.veth.pair = vethmycontainer
lxc.network.ipv4 = 125.67.43.102
lxc.network.hwaddr= 02:00:00:86:5b:11

lxc.devttydir = lxc
lxc.tty = 4
lxc.pts = 1024

lxc.arch = amd64
lxc.cap.drop = sys_module mac_admin mac_override
lxc.pivotdir = lxc_putold


Containers etc/network/interface



auto lo
iface lo inet loopback


auto eth0
iface eth0 inet static
address 125.67.43.102
netmask 255.255.255.0
broadcast 178.33.40.255
gateway 125.67.43.1


This is how my configuration is




-------------        -----------         -----------   
| LXC | -----> | Host OS | ------> | Gateway |
| Container | | Ubuntu | | |
------------- ----------- -----------
eth0 125.67.43.102 br0 <-> eth0 NAT GW:
gw 125.67.43.1 br0 125.67.43.100 125.67.43.1
gw 125.67.43.1

Ping 125.67.43.100 ping 125.67.43.1
ok OK

Ping 125.67.43.1 ping 125.67.43.102
FAIL OK


LXC container is not know outside host, any idea what i made wrong here?



Additional info




user@host$cat /proc/sys/net/ipv4/ip_forward is 1





I have added Nat rule




ip_tables -t nat -A POSTROUTING -s 125.67.43.102 -o eth0 -j MASQUERADE




Note: IPs I have used above is not original

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits,

apache 2.2 - Server Potentially Compromised -- c99madshell

So, low and behold, a legacy site we've been hosting for a client had a version of FCKEditor that allowed someone to upload the dreaded c99madshell exploit onto our web host. I'm not a big security buff -- frankly I'm just a dev currently responsible for S/A duties due to a loss of personnel. Accordingly, I'd love any help you server-faulters could provide in assessing the damage from the exploit. To give you a bit of information: The file was uploaded into a directory within the webroot, "/_img/fck_uploads/File/". The Apache user and group are restricted such that they can't log in and don't have permissions outside of the directory from which we serve sites. All the files had 770 permissions (user rwx, group rwx, other none) -- something I wanted to fix but was told to hold off on as it wasn't "high priority" (hopefully this changes that). So it seems the hackers could've easily executed the script. Now I wasn't able
