I have a small public IP block (/29) I'd like to populate with VM's from a single physical box running CentOS/5. I'd like to get some thoughts on the best way to setup networking to support this. I'm OK with setting up the virtual hosts. Any advice would be appreciated. TIA...

How do you modify the default network parameters? The net-edit command within virsh does not seem to work as expected. TIA

Actually - as I stated - I have cross subnet browsing working (and thus wins). And I do have a samba box on both ends. The behaviour I noted happens irregularly: sometimes I can open a share on the other subnet, but mostly I cannot not. I'll still have a look at your suggestions though, it might help.

Silvertip257, when you did this CentOS 6/KVM/bonding/bridging, did you ever get all the parts playing together correctlhy? I'm facing a setup with only two NIC's, and need for multiple trunked VLAN access, and bonded pairs, and KVM based bridges to get the VM's with exposed IP addresses. I can get basically any 2 out of the 3 server network components working, binding, VLAN's, or

I have several (various brand) sip devices with static IP's. I understand that asterisk will not accept a registration from these devices if the host= parameter is not set to 'dynamic' in sip.conf. I want calls to these extensions to be routable even before the device registers. I understand that is what defaultip= is supposed to do, but it doesn't work. I get a busy tone when

Greetings: Wea re running a older version of linux (5.2) and I need to pull data off of that box to move it to a new system. I have attempted to configure samba but have not been sucessful. My smb.conf looks like this: [global] workgroup = WORKGROUP encrpt passwords = yes [test] comment = testing path = /backup read only = no gueat ok = yes Win 2k clients and win98 clients cannot

I can access Samba and Windows share on my newtork (I have Samba on linux server) and some W2K Server. >From my SUSE 9 Professional client within Konqueror I can create, delete file, rename and even overwrite files on the share of my server (Samba or Windows). But When I open the file (file.txt or any other type) within Konqueror on a Samba share (by example right clicking and choosing open

I'm difficulty diagnosing a tftp-hpa problem. Specfically, when performing a PXE boot, the machine hangs at the "TFTP...." and times out. This is only occuring at one network location (we'll call it network A). Now on network B, the computers on network can tftp boot no problem. If I run a tftp client from my workstation to connect to the tftp-hpa server on network A, I can

Hi, I have what to me is an interesting issue. I am wanting to prioritize (QoS) traffic that will be passing through an IPSec (OpenS/WAN) VPN between two (identical) Linux routers. I know that I can apply the IPSec patches (1-4) to the kernel and IPTables (if they are not already applied by now) filter traffic before and after IPSec encapsulation. My problem is that I don''t know

Hi, We have configured several xen guest OSes on a server running SLES10. The physical server is a Sun 4200 with 3 NICs installed, configured, and working. Each of the xen guest OSes have three virtual nics, configured for RAC, Interconnect, and public IPs as follows; eth0 - public (routable and registered in DNS) eth1 - private (not routable, uses a seperate network subnet for

Hi all, i''ve coded htb-gen, a GPL htb frontend and much more... htb-gen is meant to be an easy, scalable, yet powerfull, bandwidth management tool. You can set up/down portions of bandwith for each host or network, that goes trough your router/firewall. Prioritary traffic(web, mail, gaming, ftp, voip, streaming) is preferred over Junk traffic(kazaa, emule, etc). Also dynamic bandwith

We have a couple oracle RAC servers that we install samba/winbind on. These servers require multiple NIC's / IP's. The problem is when we do "net ads join" it updates windows DNS and really screws us up because seven IP's get put into DNS, all tied to the same host, including the interconnect IP's which oracle insists needs to be 169.254.x.x addresses. Because of the

Hi, Question on setting up networking in xen. I want to do the following on my laptop: dom0 is attached to eth0 and ath0. dom1 is going to by my virtual firewall for all my virtual machines. So I assume 3 interfaces, a bridge to eth0, ath0 and a virtual interface? dom2 and so on will route all their traffic through dom1 (through the virtual interface) I''ve read the documentation a

Hi, For Ethernet and others, we have a configuration file inside /etc/sysconfig/newtork-script/ like ifcfg-ethx where we specify ip address, mask, type etc... For GRE tunneling, how can I specify the parameters for tunneling device, so that I ifup-tunnel will automatically read and start the interface and I don't have to write the below scripts in my start-up file. ip tunnel add netx mode

Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

this is the case: serverA [ CentOs 5.6 kernel 2.6.18-238.12.1.el5.centos.plus, Samba ver. 3.5.21 ] serverB [ CentOS 5.6 kernel 2.6.18-348.1.1.el5.centos.plus, Samba ver. 3.6.6-0.129.el5 ] clientA [ WindowsXP ] clientB [ WindowsXP ] The serverA shares via Samba the resource [test] [global] workgroup = DMIT netbios name = SAMBA server string = DMIT domain server interfaces = eth0

I''m rate limiting and prioritizing traffic upstream of a slow wan link using htb, classic wonder shaper type stuff. I''m using the following command for traffic that does not match any of my defined filters: tc qdisc add dev eth0 root handle 1: htb default 50 It appears that local, non-routable traffic like arps and igmp are being snared by this and end-up queued in the lowest

Hi, Recently I'm noticing an interesting issue. My CentOS servers are trying to send logs to a logging server via 514/udp, however I'm not receiving anything. I did the following on CentOS *tcpdump -vvv -nn udp -i esn160 port 514* In another session on the same server: *nc syslog-server -u 514* tcpdump started to show me messages like: *[bad udp cksum 0x3ce9 -> 0xb0f5!] SYSLOG,
