celtclient 64kbps more than expected
Hi, The default settings for celtclient are:- Sampling rate 48000 Frame size 256 Packet size 43 According to my calculations this should give a bitrate of 64kbit/sec + a little extra for the 32bit time stamp and 4 null byte pseudo header. Using vnstat I was very surprised to see that it was reporting a bitrate usage of around 16kbyte/sec which is 128kbit/sec, double what I was expecting. I

Intel Quad NIC made visible in guest -> system crash
Hi! we have two Intel Quad Nic 82576, PCI ID 8086:10E8 and use the igb driver 1.3.19.3 on Debian 5.0.1.

NIC traffic monitoring, recording and reporting software?
I have a remote CentOS-5.3 installation that shares traffic with another enterprise. I want to record and measure the actual network traffic that comes into and goes out of that host's net i/f on a monthly basis for billing verification purposes. Does CentOS have a software package to accomplish this? I have run across references to a package called vnstat as a possible answer to my

CentOS 5 sshd does not log IP address of reverse mapping failure
I'm running a mix of CentOS 5 and 6 servers reachable by ssh from the Internet. Of course I allow only public key authentication and no root login. In addition I'm running fail2ban to block obnoxious brute force attack sources. On CentOS 6 this is working pretty well, but on CentOS 5 there's one class of attacks fail2ban fails to ban. (No pun intended.) This isn't fail2ban's

How to diagnostic UDP discovery failed situation
I found the server(1.1.1.1) didn’t receive the MTU probe from client, so I add iptables -A INPUT -p udp —port 443 -j ACCEPT. After this, I see one packet matching on the server side, and the MTU negotiation works, but when I tear down the tinc, and re-establish the tinc connection, the counter of below UDP/443 never increase, and also my other tinc nodes never add this statement on iptables, but

How to diagnostic UDP discovery failed situation
Hi, experts for example, the below case: You can see a lot of back and forth MTU probe packets been exchanged between tinc nodes, but it’s weird that, from the debug log, one line shows "No response to MTU probes from node1”, but it indeed received a lot of MTU probe response, and finally it get the conclusion of "Packet for node1 (1.1.1.1 port 443) larger than minimum MTU”.

What/why this event happens: Can't write to Linux tun/tap device (tun mode) /dev/net/tun: Input/output error
Hi, Guus Thanks a lot for your suggestion, actually I did something else as below. But one question here is if I don’t add "/sbin/ifconfig myvpn 10.0.0.1 netmask 255.255.255.0”, it seems the crontab wouldn’t trigger tinc-up, and then the ip addr of myvpn wouldn’t be configured, then it will prompt the error of "Can't write to Linux tun/tap device (tun mode) /dev/net/tun:

A FAQ: is it mandatory to include the local IP address classes in the global VPN address class?
Hello, Since the present tinc documentation is not very clear about this, please explain the following: is it mandatory to include the local IP address classes in the global VPN address class? Namely, please consider the following setup (which works great in practice): 1. A tinc VPN, full mesh, with n nodes (n > 3) 2. tinc runs on the firewall, which is also the default gateway for each

Tinc 1.1pre15 double-crash
Hello, this morning I apparently had tinc crash on me. In 2 independent tinc clusters of 3 nodes each (but located in the same datacenter), one tinc process crashed in each of the clusters. One process apparently with `status=6/ABRT`, the other with `status=11/SEGV`. Interestingly, they crashed with only 5 minutes difference. The only thing I can come up with that might explain this correlation

Network bandwidth tools.
Hi All, I am wondering what tools are available in CentOS 5.5 that would allow me to measure incoming and outgoing network speeds? My new website seems to be getting a lot more traffic that I had anticipated off the bat and I would like to measure resource usage to ensure it is keeping up. I know that top only measures CPU Best, -Jason

[Bridge] Measuring Bridge Performance (+ebtables/iptables)
Hello, has anyone done any performance measuring of Linux Bridge + firewalling? I did search the net for a long time, to find out what would be the best way to measure the (maximum) performance/throughput. I didn't really come to a conclusion I'm satisfied with. Nevertheless I did create a small bridged test setup with 4 servers (gbit nics) and a linux bridge (2 x 100 mbit nic), all on
