I have an Asus WL-500G Premium router with OpenWRT, with built in 4-port switch. There is one server connected to each switch port. Is it possible to give a description to every switch port in Asus WL-500G Premium? This description should survive reboot as well Is it possible?
View 1 RepliesServer is on Port 1, with an address of 10.3.2.1.
Someone plugs into Port 2 and gives themself the same address.
That would cause problems, right?
So, is there a way, to say to the switch, "Hey, 10.3.2.1 is on Port 1, and nowhere else. Do not let anyone use the IP 10.3.2.1 on any other port, and if they do, disallow the traffic."
made software which we can get network traffic Report of of Switches for Daily,monthly and yearly base , in MRTG we can configure as a switch so we can get particular switch Traffic but how can we get each port of traffic of a switch in MRTG

View 5 Replies View RelatedMy main wireless is an ActionTek DSL modem: it handles my incoming DSL, all my DHCP and DDNS, and it's a good Wifi base station throughout the house. Life is Good. I want wired access to a desktop PC upstairs: I tried a USB wireless stick, and it just isn't cutting it. I'm hoping I can use an old WRT54G wireless router, install some hew firmware, and use it as a wireless access point. I would like to plug the desktop into the WRT54G (cabled), have the WRT54G get a DHCP address and register the desktop's hostname in DDNS (wireless), and have everything work.
Q: Is "wireless access point" the correct term here?
Q: Should I go with OpenWRT (suggested in a previous post: looks very promising), DD-WRT, or Tomato?
I am looking for a router and trying to decide which one to go with based on the firmware I will want to use. I like how Tomato has alot of graphs and can show alot of graphical data. Does DD-WRT or Openwrt have as many graphs available?

What are the pros and cons of various current model ADSL modem routers for use with DD-WRT, OpenWRT or Tomato? There are, of course, hardware compatibility lists (HCLs) for each of these (DD-WRT, OpenWRT and Tomato) but many of the models are no longer available and there are so many that researching them all would be onerous. Many pages on the Internet recommend the WRTG54L and that would be great but it is no longer an option except second user which is increasingly difficult. What are the pros and cons of the various chipsets: ADM5120, AR7, IXP4xx and BCM63xx?

I have a device that must use a real IP address. Currently, my ISP uses DHCP and I can have up to 4 real IP address assigned. However, the cable modem only have 1 ethernet port and it's connected to my router (running Tomato, but can run DD-wrt or other Openwrt if required). Question stems from how I can connect the additional device, requiring a real IP? would be to get a switch and connect to the CM, Router, and Device. But alas, I want to avoid this route, since:
my wiring cabinet in my home is drawing lots of power and heat already Device will be unprotected by any firewall unable to monitor the traffic to/from device.Besides, what would be the FUN in that? what I want to do is to configure the router, so that one of the switchport is removed from the normal br0 bridge. Instead, I want to make it behave like a switch on the WAN port. What's the best way of doing this? Should I create another bridge on the WAN & the device port? Can a single port belongs to two bridges? or would I need to create a subinterface first? Would I need a DHCP-relay? Am I expecting too much from my poor cheapie router?

I have 2 HBA's in my system, in that one shows as READY state and the other HBA shows as DEAD state. I have asked the datacenter guys to to connect the HBA to another switch port and I rebooted the server. After reboot the second HBA came to READY state but after some time again it went to DEAD state.
Host adapter:loop state = <DEAD>, flags = 0x45a03
Is this the problem with the server or with the storage end
I would need to monitor the status of an electric relay. To do so I was thinking the serial port and perl (as I don't know C ) how to check if a switch connected to a serial port is open or closed. Here is my plan, I'll plug a electric relay on the electric network and monitor the state of the switch. if the switch is closed, that mean that we are on the electric network if the switch is open that mean that we are on our diesel power generator.
PS: There will be no voltage input involve (although I can if that's required)
I'm planning to use this with Nagios to know if we are on the electric network or on our diesel power generator.
I dual boot Windows/Fedora 11 on my Dell Latitude D830 laptop, which has an Intel PRO/Wireless 3945ABG card and I have just bought a Linksys WRT160NL wireless router. I am currently trying to set up OpenWRT linux on the router. Because of the nature of my problem I have also posted this on their forum.I am having trouble connecting to my OpenWRT install via Fedora. Things seem okay in Windows, but when I try to connect from linux my laptop locks up completely and I have to hard reboot. I previously have never had any trouble connecting to any other router with this install of Fedora.
View 3 Replies View RelatedI just spent an hour at Google and the OpenWRT site looking for something that might be called a "List of Features." I did not find one.
I did find this: url but it is not an official project document so I'm left with as many questions as answers.
I know that OpenWRT uses dynamic packages for feature deployment, but I'd expect some sort of grid page -- package vs. edition -- or similar so that one might have some idea what is available to choose from.

I know that part of the Linux sociology involves some amount of "you just gotta know." However, unless one is a networking maven or wonk one does not know enough about network features to state which features one wants ... much less know what name to use in search or discussion.
I was wondering if anyone knew how to get long package descriptions which searching for packages with aptitude.my search results have package descriptions that are truncated even if the terminal is expanded to allow longer one-line package descriptions.

I'm trying to use iptables in order to forward all the incoming packets for port 5555 to port 5556 on the same server (192.168.2.101).
I wrote the following commands:

iptables -A FORWARD -p tcp -m state --state NEW -d 192.168.2.101 --dport 5556 -j ACCEPT
I'm using a Debian servers, as router/firwall.. I've two ethernet interfaces into the server, one for wan and one for lan. The i use SNAT so my LAN clients can access the internet throgh the debian router. That is working... Now i want to be able to access servers on the LAN site from the WAN site, and i wanna use port address translation (PAT). I have a FTP server running on a lan server, so i'm trying to portward port 21.
iptables -t nat -A PREROUTING -p tcp -i eth1 -d (WANIP) --dport 21 -j DNAT --to 192.168.1.2:21
When people try to access my FTP from the WAN site, they are redirected to the local FTP server, and they are promted for crendentials, but when the credentials are typed, and the local ftp server should answer the wan request, the connections dies.
The wan clients are being promted for credentials, so they are redirected to the local lan server, but after that the connections dies, so i think there is some kind of nat problem, when the local lan server is trying to respond to the wan request..

I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 225.0.0.1/23451 and 225.0.0.2/23452
Receiving on 225.0.0.1/23452 and 225.0.0.2/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [225.0.0.1/23452] take its datagrams from emitter [225.0.0.2/23452] and vice-versa!

i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.
