Where can I find examples of configs to emulate WANs, I am looking for slow speeds and high latencies. Thanks

Okay, here is a very simple QOS scheduler that delays packets for 2.6. It is good for testing, and might be useful for people who want to put some class of traffic into a "penalty box". Alexey''s tc command is really easy to extend to new disciplines. There is a version which knows about this scheduler at: http://developer.osdl.org/shemminger/tcp/iproute2-delay.tar.bz2 The

I need to decide on the best way to add a voip SIP or IAX client to a website. I'm thinking that I'd like it to be inline, like an aplet, on the page. I've got some asterisk servers running to connect up to, so the real challenge is finding an easily integrated open source client. Any suggestions from those who know? Jason

Hello, I am thinking of connecting a Shorewall Firewall to three different ISPs and load balancing some but not all connections. Just asking for some advice for now. Here''s the network layout: ISP1 ISP2 ISP3 ADSL Router 1 ADSL Router 2 ADSL Router 3 | | | FW:eth0 FW:eth1 FW:eth2

Here''s my situation: I''ve got an Intel machine running a 2.6.9 linux kernel and this box has 4 modems attached to it via a usb to serial port expander. In order to force data down each of the modems, some pretty simple rules are used and they are as follows: iptables -t mangle -A OUTPUT -p tcp --dport $PORT1 -j MARK --set-mark 1 iptables -t mangle -A OUTPUT -p tcp --dport

Hi! I got some strange problem with routing loadbalancing. I cannot get the full speed from my ISPs until I get some big files from close ftp server. I have server with one connection to internal network and 3 to ISPs: __________ | eth1|---- ISP1 | | internal--|eth0 eth2|---- ISP2 net | | (~300 | eth3|---- ISP3 hosts

Hi everyone, I''m doing some networking experiments over high BDP topologies. Right now the configuration is quite simple -- two Xen boxes connected via a dummynet router. The dummynet router is set to limit bandwidth to 500Mbps and simulate an RTT of 80ms. I''m using the following sysctl values: net.ipv4.tcp_rmem = 4096 87380 4194304 net.ipv4.tcp_wmem = 4096

I first met this problem when our (60 students) internetgateway refused to boot its new kernel, it was a 4.7-RELEASE. Then i loaded the old kernel and went home to check if my 4.8-STABLE does likewise. And the answer was yes! Both kernels were GENERIC + these options taken from the dummynet man pages: options DUMMYNET options NMBCLUSTERS options HZ When i boot the machine

Hello, I have finished setting up the load balancer with IPROUTE ... also patch the kernel to support DGD and now it''s working fine with the valuable guide at LARTC website, Julian Anastasov, and the kind people in this mailing list. Now I would like to launch a web server and a ftp server to the public but I''m stuck into a problem and really need your help. Currently internal

Hello, Thanks for the great Shorewall which has replaced my hard to maintain home-made scripts. First, what works. Our local network is 10.48.X.X with multiple vlan, each on a dedicated interface. We use Shorewall 4.4.11 from Debian Squeeze. We have a 2 ISP: - isp1 : an optical fiber provider with 10 Mbps. - isp2 : a DSL provider with 15Mbits/1Mbits. We use isp2 as the default outgoing

We''re trying to figure out how to have equal cost multipath routing using OSPF (quagga) and have come up with the following... Has anyone done something similar? -- How do you deal with incoming services (mail/web/etc) in such a scenario as below - And does anyone have any suggestions? There''s more detail below.... Diagram and overview: Network A connects to Core1 and Core2

Greetings, Scenario: Centos box with eth1 (10.0.0.0/24) and eth0 (192.168.0.0/24) segment on eth0 has access to full bandwidth of uplink Both are on 100mbps switches Requirements: bandwith on segment on eth1 needs to be throttled to different speeds - say 32, 64, 128kbps and the such. Required for application performance testing purposes. As usual my girlfriend google is very verbose.

I''m attempting to perform some class based routing using Linux in combination with quagga/zebra. My current experience is with FreeBSD/ipfw/quagga. I''ve read most of the LARTC documentation as well Martin Brown''s Guide to IP Layer Network Admin. Here''s the basics of my set up: |- R1 <-> ISP1 R0-| |- R2 <-> ISP2 | |- R3

Hi. We just opened a gaming center and have chosen to run a FreeBsd box for our firewall. IPFW is configured at it's very basic running natd through rl0 and allowing any to any connections from the lan to the outer world. Natd controls access to the lan. We have a 6.0 mb/s ADSL net connection for all the gaming clients to use, however if a gamer starts downloading a file, that file

Hi all! After that good thread "DGD patch not detecting dead gateway" I was able to set up a Load Balancing with ping based DGD (without Julian Anastasov patch). But now I''m facing a new problem and tried some options, with only partial solutions. I made a script based on http://www.mail-archive.com/lartc@mailman.ds9a.nl/msg16257.html (Thank you Manish Kathuria),

Howdy all, I posted this message to the netfilter mailing-list and didn''t get much response. I apologize if anyone here is getting this for a second time. Anyway, I recently migrated my firewall from a FreeBSD box running ipfilter, ipnat and dummynet to a Gentoo Linux box running netfilter and tc. I have to admit that I''m having problems visualizing tc in my head. So, I was

I am working with the telantek.adsi file, and I was wondering how I would create a softkey for Transfer. I tried making a key definition and using SENDDTMF "#", but that didn't work. Is there another way I could do this? Also, does anybody have any ADSI scripts for use with Asterisk that they would like to share? Thank you for your time. __________________________________ Do you

Winamp3 is broken according to some posts here. Try Winamp 2.91 or the latest XMMS. Of course, XMMS requires the xmms-mp3 libraries. Try that and see if it helps.

I recently set up Asterisk with an Adtran TA750. All is well except the phones do not show the MWI. I have configured zapata.conf properly, as all phones will receive a stutter dial tone if there is a message waiting in it's assigned mailbox. Does anybody know how I might fix this problem?
