In following up on the rsh "problem" I was having earlier, I decided to try out the suggestion Felipe sent about using system-config-securitylevel-tui to open up ports 513 and 514, but that doesn't seem to do the job, either. # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere

Situation: Running a simple UDP client/server program where the client on one domU on one computer sends echo packets to another domU on another computer, server sends echoes back. They do this on a specified port (will use any port between 5000-6000). This program works on non-Xen machines in various environments, Linux and Solaris. Program just hangs on the domUs. I believe I need help with

This is a standard RedHat / CentOS firewall configuration, where I told it, through the standard RH setup GUI, that I want ssh and snmp allowed through.

Hi All, whilst not being an expert on iptables, the below ouput of iptables -L seems too insecure to me. Does anyone agree.? Perhaps I'm not understanding it as well as I think I am.? Please give your thoughts on this. Cheers. Mark Sargent. [root at localhost racket]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all

Is there a way to add a rule to the nat table (CentOS 5.7) that would alter the port number of tcp packets destined for the server itself? I have ip_forwarding enabled, but the packets don't seem to hit the prerouting chain. I have the following redirect rule in the prerouting table. I also tried DNAT, but if the packets don't hit PREROUTING, it won't work either. iptables -t nat

Hi, I''ve been making leaps and strides with Xen on FC4. It has been easy to get installed and to start our first virtual host. I''ve got one outstanding issue with iptables that is preventing me progressing further. This is a colo''d server. It has s single NIC with public IPs. The bridge is set to come up binding vif* <> xen-br0 <> eth1. I can start a

Hey, I was originally asking questions on xen-users but no one seems to have any idea about this so I figured I''d try this list. I compiled Xen from source (3.2 testing) on an Intel machine running Fedora Core 8 and have discovered that my guest (Windows Vista) does not have a network connection. Looking at various online documentation and a machine that does work, I guessed that I

I have a simple requirement/test I'm trying to perform, but having difficulty. I have a system with 2 interfaces, BoxA: eth0? 172.26.50.102 eth1? 192.101.77.62 My goal is to have a tcp port built on BoxA such that hosts on the 192.101.77.0/24 network can reach a port on a different box on the 172.26.0.0/16 network. The target system is 172.26.10.120?? tcp/22 The port I wish to build is

CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere. I want to keep the

Hello all, Basically my problem is how can i access a virtual machine from local network.

Here is an extract of my current iptables that are not working: iptables -L -n -v Chain INPUT (policy DROP 8 packets, 1120 bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT tcp -- lo * 0.0.0.0/0 0.0.0.0/0 tcp dpt:3306 0 0 ACCEPT udp -- lo * 0.0.0.0/0 0.0.0.0/0 udp dpt:3306

Running CentOS 6 I have noticed that Libvirt will automatically configure IPtables once a VM is using the built in NAT , or "default" network. How do I modify the IPtable rules without breaking libvirt's ability to configure these rules? This is the firewall settings on a fresh install with no VMs using virbr0... -------------------------- Table: filter Chain INPUT (policy ACCEPT)
