I''ve setup Xen 3.0.2-2 (binary install) on Ubuntu 6.06, got my domUs up and running, got them connected to the Internet but I can''t even ping to any of these VMs. Now I''m not linux/xen genious but could the problem be that xen-br0 doesn''t have an IPv4 address?

Hi everybody, Right now, we are blocking pings and traceroutes to our website. But, in order for our members to test the connection when they are experiencing slow browsing, we are thinking about unblocking them... Are there still any security issues (flooding, etc...) in enabling them or is that an old problem fixed a long time ago? Thanks, JD

hi, how to write a scripts which launches 10 pings to different destinations at execution of single shell scripts please help me any ideas regards, Gopinath

Hi All, If I have a vlan-Id on an interface with an ipv6 address, then I am unable to ping a real router. The problem is that the Neighbour Solicitation originated from the Centos machine is missing the Vlan-Id in the packet. Therefore a real router will drop such a packet. I have tried this with Centos 4.7 and with Centos 5.5 with the same result. If I originate the first Neighbour

Hello @all, thanks for all the helpfull answers in this mailing list. They helped me compiling a new kernel 2.6.10.11 with Xen 2.0.6 (my first one), setting up a dom0 with RAID, LVM and loop devices for domU, integrating a second network as xen-br1 (I''m calling the /etc/xen/scripts/network script from within /etc/init.d/xend to bring up / down the second bridge.) and bootstrapping

I'm having a wireless connection issue with an HP laptop and a Zotac media server after the 6.4 package updates from CR repository. Nothing changed with wireless config as far as I can tell. Both have been working fine with previous releases of 6.x. Oddly, if a cat 5 cable is connected for a few seconds and then disconnected the wireless works fine and survives a 'service network

Hello everybody, I''m new to Xen so forgive me if this is already well known issue. I''m using Ubuntu server 7.04 (feisty) with Xen 3.0.3 Everything works perfectly, apart from networking in NAT mode. With bridging it works, with NAT it works, well, quite strange. Namely, pings go through and name resolution works. But when I try to use anything substantial, then

Hello, I have shorewall installed on a dedicated server from OVH This gives me a server monitoring service, but I have set to drop ICMP ¿I can configure shorewall to only accept pings from certain ips? thanks. best regards, Santiago. ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for

I've turned on debug in a (IAXComm based) soft phone. I see the phone sending pings to *. I see * getting the pings. For some reason, with iax2 show debug, I never see any response on the console from *. However, the phone shows a response with INVAL. Seems like an odd response to a ping request. I believed it should get an ACK. Is that wrong? If I should get an ACK, what could I have messed

I apologize for the TLDR-style email, but I wanted to demonstrate that I have done a lot of work (11 hours and at least 8 tutorials including the tinc docs) before asking for help. My basic problem is this: tinc appears to properly connect and authenticate the client to the server, but I cannot ping or access resources. (yes. I know there is no 'server' in tinc, but 'server'

The situation is this: INTERNET -- ROUTER -- ETHERNET+WIFI -- PC's The conection between INTERNET and ROUTER is done with 2 LINKs with static IP's. The conection between ROUTER and PC's is done via ETHERNET lan with many bridges and ACCESSPOINTS. The PC's are in a IP subnet, the BRIDGES in another IP subnet, the AP's in another IP subnet. The ROUTER has 1 bridge interface

Hello All, I am running NTFS over iSCSI on a ZFS ZVOL volume with compression=gzip-9 and blocksize=8K. The server is 2 core P4 3.0 Ghz with 5 GB of RAM. Whenever I start copying files from Windows onto the ZFS disk, after about 100-200 Mb been copied the server starts to experience freezes. I have iostat running, which freezes as well. Even pings on both of the network adapters are reporting

I don't know everything that's going on as someone else has been working on the project, but it hasn't really been going anywhere, so I had some questions. We've got some Snom 320s with Asterisk 1.2.9.1 (I believe). All was well (with a previous release), but the phones started to get real choppy. We are also running a softphone at this location and it was fine. The SIP qualify

Greetings! I am working with Lustre-2.1.2 on RHEL 6.2. First I configured it using the standard defaults over TCP/IP. Everything worked very nicely usnig a real, static --mgsnode=a.b.c.x value which was the actual IP of the MGS/MDS system1 node. I am now trying to integrate it with Pacemaker-1.1.7. I believe I have most of the set-up completed with a particular exception. The "lctl
