I will be setting up a LAN at home where there will be a few PCs connected to the network.
My idea is that I will have linux box where I will route all the traffic through to monitor it. I was wondering what would be a free solution to go "hardcore" on this. When I mean hardcore, I really mean hardcore. I want stats, packet shaper etc.. It would be a learning process for me too. The only thing is that alot of solutions out there are more enterprise and expensive.
Anyone here use or know a good solution? I was told I could use m0nowall on freeBSD. Another thing I was looking at would be Squid. But to be honest I'm not sure.
Whats a good free software that can do this? Perhaps something really cheap if there is a cost involved.
I'm working on setting something up for monitoring my bandwidth/traffic on multiple interfaces. I have setup interface aliases so I have eth0, eth0:0, eth0:1 and the issue I'm running into is that it seems snmp cannot tell the diff between the aliased interfaces. I've found references in the cacti forums of using ipchains rules to track the bandwidth, but I've not found a good howto that explains what I need to get going on this.
I currently have a windows 2003 server box which is being used only for huge file downloads (Media server). Wanted to know if there is some sorta program or script that lets me check the current connections and what speed each connection(ip) is downloading at?
I currently have 2 VPSs that I'm monitoring and I noticed that on one of them the memory usage is much higher than the other which doesn't make sense to me. I tracked the high memory usage to the Apache processes.
Here's the overview of the VPSs:
LiquidWeb VPS- 512MB RAM, 10 Sites with minimal usage. Average httpd process (Owner Priority Cpu% Mem% Command): nobody 0 0.0 1.2 /usr/local/apache/bin/httpd -k start -DSSL
Virpus VPS- 384MB RAM, 61 sites with moderate usage. Average httpd process (Owner Priority Cpu% Mem% Command): nobody 0 0.0 0.3 /usr/local/apache/bin/httpd -k start -DSSL
Both Apache configurations are identical, the only difference besides the hardware is that LiquidWeb runs CentOS4.7 and Virpus runs CentOS5.2, any ideas? It's not to big of a deal since I'm not near my limit for either of them but I was just curious.
what's going inside my provider Powervps/Defender hosting, they are offering now 25% OFF of new customers + triply bandwidth.
Curent customers are not allowod to get this offer, until they order a new VPS and cancel the older.
I'm asking, because i feel, it's samething, why they don't go upgarading the account throughly with keeping IPs and data..? why do old customers need to cancel the old VPS then they go get a new VPS..?
are Old VPSs powerfully then the newest..? any informations...?
In order to increase the reliability of a audio streaming service I am thinking to take the action I describe below.
1. Buy two Windows VPSs with WMS installed.
2. Register a domain name (i.e audiostream.com) with 4 nameservers: ns1.ip1_vps1, ns2.ip2_vps1, ns3.ip1_vps2, ns4.ip2_vps2.
3. Create all publishing points (streams) on both servers.
Normaly VPS1 should serve all clients. In case VPS1 goes down, VPS2 should jump in and serve all clients-connections. As soon as VPS1 becomes available (ns1 & ns2 start responding again), VPS1 starts serving all new connections.
Load balancing or any other kind of advanced load, traffic, etc management is not important.
Then we have the following cases: 1. VPS1 is down , which means that VPS2 should take charge.
2. VPS1 is up (ns, http, ftp services), but WMS1 is down (crashed). Means that the playlist (asx) file should be built so that it also includes the IP, port & publishing points of VPS2. This should be done because ns1 & ns2 will answer without any problem, but WMS1 will be crashed and won't serve any media connections, thus ASX will look for the next available stream in the playlist.
Do you think that the above is possible. Is this gonna work?
Last month I order 2 Xen VPSs from Xenvz.co.uk and use them for VPN proxy.
But a few days ago, xenvz stopped one vps and state "This is because it is spreading the Conficker virus.". I'm a little surprise because there's only 10+ users on this vps. Most of them use VPN for visting Youtube or P2P download or gaming. And Conficker virus can only run on Windows, but all my vps is running on Debian.
Maybe someone had download something that contain Conficker virus?
Anyway, I had to move a few users to another vps yesterday.
But xenvz stop my another vps today for the same reason!
I really do not know whether or not one of my user is spreading or other reason, but as I know, Conficker virus had affected thousands of hosts in the past. If someone download or being affect by conficker for any reason, provider then stop their host, I'm afraid thousands of sites would down.
Most VPS offerings have "burstable" memory allocations. I get how you can do this with most things -- letting a VPS access more CPU cycles can be done pretty easily, and a 10 Mbps line burstable to 100 Mbps makes sense.
But how does the guest OS handle all of a sudden having more memory? Since a lot of VPS guests run without modification, how does this work? Does the typical Linux system support dynamic changes in RAM? I can only imagine that dealing with "un-bursting" is even more complex: suppose I have 128MB, burst to 512, but then the host node tries to reclaim some of it. Is the system smart enough to seamlessly swap out to disk when RAM "disappears?" I'd fully expect a kernel panic when the system's RAM shrinks in size, particularly when the RAM was in use.
I'm curious about exactly how all of this is managed. Given that 95% of VPS hosts give a burstable range of RAM, what exactly manages this? Is the virtualization platform handling this and somehow "tricking" the kernel, or is the guest system able to deal with changing RAM allocations? And, if the latter, is this a standard feature of the Linux kernel, or are guest OS mods still necessary to deal with burstable RAM?
I want to monitor my application to make sure it is 24x7 uptime, if there is anything interrupt, I will be notified by email/SMS right away. There are several web monitoring service, but they all monitor ports, not application. I have bad experience, like, althoguh the web server is alive, but the application is already dead.
So, I want to monitor application instead of monitor a port. Anybody knows where I may find this kind of service?
I see a lot of web hosts that link to webhostingstuff.com which tracks the uptime of their main page. i would like to offer a similar service, where i track and list the uptime of hosts. can anyone point me in the proper direction for this? is there a particular script that I can purchase? how is this done?
My server has a tyan thunder 8kse (s2892) motherboard, and i'm looking for some script to monitor it. Unfortunately, tyan only offers such applications for windows. So, how can i monitor the motherboard in linux? Or preferably, webbased.
