View 5 Replies View RelatedI want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
I've written a script that restarts the server of a game I play, giving you a 15 second notice. If I manually start this script, it works fine. invalid option say Server is restarting in 15 seconds-ne and it says this for every line in the rest of the script (substituting the correct phrases of course, but always starting at the "say" and ending with the "-ne")

I have a script that changes the default gw (I have 2 providers) if the link is down. The script runs very well when I call it from the terminal, however when I try to set a cron job to run it, it hangs in the middle of the script. I don't have any idea of what is happening, or how to debug but it seems to hang when running a command like: route add default gw [ip]
I can publish the script here, but it's fair an simple and the algorithm is:
- start
- Find out the current GW
- Find out the alternative GW
- Ping the current GW and capture the result
- if we have a fail then change the default gw to the alternative Gw and send an email, else do nothing
- end
The cron job is run as root, so I don't think this is a rights problem.

I have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?

$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?

setuid bit allows the process to execute the file with the uid of the file. But, what is the purpose of setting setuid without execute bit? The man page tells that if a file is setuid without execute flag, the permission will be displayed as 'S' (capital s) in ls command. Why should anyone set the setuid without execute flag? Does setting setuid without execute flag have any special meaning?

I am running Linux Mint on my primary hard drive, and I would like to access some folders I have on my second hard drive, which has Windows XP installed on it. However, whenever I try to use these folders, I am greeted with the error message, "The file is not marked as executable." While I know how to set files as executable whenever I am using folders on my Linux drive, whenever I try to set such permissions on my XP folders, I can't seem to make it work. The files revert to their former status, and I'm told that I don't have permission. Should I set the files as sharable from within XP, so that they aren't marked as read-only? Or is there another solution I've missed?

I am running a web server with a public ip that is dynamic. I am using ZoneEdit.com and my WRT54GS router to manage my dynamic ip address whenever it changes. It is working as it should.
However, the subdomains ip addresses are not changing. It still shows the old addresses versus the new address. Is it possible to set it where my subdomains address will change as well?
Right now on my router under the ddns menu, I have the host name set to domain.com. Do I need to make a wildcard?

View 1 Replies View RelatedOkay, a few days ago I got a small job setting up a router for a neighbour of mine. He wanted me to set up a wireless network for him. The router he bought is a Linksys Wireless N-Router E1000. I set it up the passwords and everything. Only to find out that I couldn't connect at all to it. The main computer with a direct ethernet connection to the router was the only one that had internet. Everytime I attempt to connect wirelessly with any device, it will take extremely long time to connect, to the point where I will just quit connecting.(Example: 15 minutes of waiting, when the laptop is right next to the router)
Any ideas about what I am doing wrong here? As far as I can think of it might just be a faulty router, because the router will not implement any changes(like setting a password) I set on it. Only wired connections seem to work. the router is called a linksys wirless N-router E1000.
World of Warcraft requires that TCP Ports 1119, 1120 and 3724 are forwarded. The Blizzard Downloader requires that TCP ports 3724, 1119, 4000, 6112, 6113 and 6114 are forwarded. It can also benefit from having ports 6881 through 6999 forwarded. The World of Warcraft Voice Chat feature uses UDP Port 3724.
i use the hotspot feature to play warcraft and i am running ubuntu 10.10 ... i need to forward these ports ... any way to easily download an app to configure the phone like you would a router? its probably easy i just cant find it.
post the "perfect" tutorial for setting up a router and firewall for Ubuntu 10.10 Server 64-bit? I'm kind of a n00b when it comes to Linux, so I get really confused with some things, I have seen things on the ubuntu wiki about this... but it really confuses me =
I'm trying to setup my ubuntu sys as a router and firewall... Internet -> Ubuntu (Router) -> Switch (no DHCP on it) -> Computers I've already setup bind and dhcp3 and got those working perfectly... I've also setup Squid3 and Dansguardian for content filtering (blocking ads and such) and got them working too... I want to set it all up to be transparent, and allow the system itself to function as a powerful firewall router, giving absolutely NO issues to client computers connected, and no speed reduction at all.... I want to setup the firewall to allow all outgoing connections, but block everything incoming (stealth the network)... Forcing all http/s traffic to pass through dansguardian, then to squid...
But am very confused on how to pull this off... The system is running Ubuntu 10.10 Server 64-bit, with 4 GB of RAM, 320 GB SSD, and two 1Gb NIC cards... Sorry if I'm not very clear, I do speak english perfectly, but just kinda new to the "Linux world", I was using SONICWALL but that's getting a little too costly to my network and wanna do a free alternative... Something completely CUSTOM, not using some network security distro.
I decided to try and get my network ready for IPv6. All of my hosts are set up to do stateful autoconfig, I have radvd installed and working, and I can ping6 ipv6.google.com from my Ubuntu server. However, when one of the clients on the inside tries to ping6, no packets return and I get this message in the router's syslog:
Code:
Feb 8 17:55:17 foo kernel: [ 1344.824474] Dead loop on virtual device tun6to4, fix it urgently!
So what I want to do is setup a gateway(or router, idk what Ubuntu refers to it as.). So my set up would be Modem>Server>Switch>Router. I know that I need to set up it up as a DHCP server as well. I would also like to setup it up as a firewall too. I already have two Gbit cards that are already configured. So how do I do this? I already tried one tutorial, but it was old and was for Debian. I also installed ebox, but I couldnt figure that out either.
View 1 Replies View RelatedThe problem isn't with thew new computer but with my computer running Ubuntu. The problem is that I'm having trouble getting the Internet to work. Before the router I just plug my PC straight into the modem but now with the router I can't get on the Internet. I can get a connection to the router but no Internet. I know the it is not the router because I use my PS3 and it worked fine. I spend like an hour just trying to get the connection but can't figure out the Internet problem. What I did to get the connection is copy the ip address, Mac, and etc. from the PS3. Then I made a new connection and put the data in the IPV4 settings and it got a connection but I'm not sure if I did that right or just got lucky

On my laptop (HPDV7), using DHCP for network access, KDE4.
I use Network Manager to manage wired and wireless connectivity.
I also have Samba server running for connectivity to Windows machines.
My router runs DD-WRT.
How do I tell this HPDV7 system to propagate a Host Name up to the router?
In the DD-WRT status screen, I see Host Name as "*" associated with the assigned IP address.
I cannot, for example, ping my HPDV7 machine from my windows machine, I assume because the router (also providing DNS for my network) does not provide the name to address translation.
I CAN ping the IP address directly, and Samba connectivity from the Windows machine to HPDV7 works.
