how to check ethernet connections in debian??
my server has 2 nics, how do I view them and their usage uptime etc in debian stable
I wanna see if they are being used randomly (usage on both), or if it hasn't been already setup and I need to do it (found a tutorial on how to do this, but dont' wanna fix it, if it ain't broken)
I now have to move on to the question of Ethernet ports in relations to rack mount servers. I have just about ever question answered now. Now my question is about the connection to the web my server will use. Is it better to have a single or a dual Ethernet post?
I see a lot of duals. Here are some of the samples I have read when building my server.
2 x Intel® 82546GB Gigabit Ethernet Ports
Dual Onboard Gigabit Ethernet LAN Ports
Dual Intel® 82541GI Single-port Gigabit Ethernet Controller
Broadcom dual Gb NICs
Intel dual Gb NICs
Broadcom BCM5754, 10/100/1000Mbps
I don’t know which one to look at or get?
There use to be a thread on here but because of the wht hack, it didn't get saved...so now I can't go back to it.
It was a command in ssh that printed out a number of connections. Like 12,000 or something.
I am facing to this trouble: apache max out the number of connections. When viewing status, all I get here
Code:

which account on server is the reason please? I am on CentOS box with DirectAdmin.
I just ordered a server which has that setup:
AMD Athlon 64 X2 6000+ Dual Core
8MB RAM
2x750GB RAID 1 HD
Now I wanna run it with DirectAdmin, but obviously DirectAdmin doesn´t support the Debian 64 which is installed but only 32 bit Debian.
Now I wonder wether I could setup a Debian 32 as well on that system and if yes, wether it would give me a deficit in Performance?
Or would you rather go with CentOS 64 which Directadmin supports?
Can anyone recommend a product that converts a DS3 to an Ethernet connection?

1. A NAS (e.g. Lacie or Thecus) with 1GB port connected to a gigabit switch
2. An external storage that uses USB 2.0 interface
3. An external storage that uses eSata inferface.
Assumption:
All of it use sata drives under a raid 5 configuration.
would you recommend some PCI with 2 or 4 Ethernet 10M ports?
View 1 Replies View RelatedSay I have my own office to start building out my own "mini" data center.
If I wanted a lot of bandwidth for the most reasonable cost, how do one go about buying bandwidth from various providers? What is Metro-Ethernet vs. say a DS3? I know there is Fractional DS3 (6 to 45mb/s) and then Ethernet services up to GigE. I'd rather not mess with BGP right now either.
If I am looking at 15-20mb/Sec of bandwidth, what would be a good route to go? My budget is about $1500/month for bandwidth and IP Addresses (I need 2 Full Class-C IP Spaces). I also want to be able to turn up speed as needed without a lot of hassle.
Is this a reasonable budget? And where would be a good place to start? Just call up like Level 3 or am I too small potatoes to even deal with?
What low-cost Gigabit Ethernet switch would you recommend for providing residential IP services to an apartment complex that is already prewired for copper Ethernet? My only real requirement is that is it a managed switch supporting QoS, capping, and has fiber uplinks.

Also the firewall stopped the port scanning from a server within the same dc.
I checked it on google and the explanation's varies but most say that is a problem of the router/switch or similar.
Say a server has 2 gig-e ports on board, and the OS
is using both. Can I still use IPMI feature? Or do I have
to get an additional ethernet card?
We're ready to setup 3-4 42U racks for servers and are in need of choosing Ethernet switches. What do you guys use and why?
I'm looked at Cisco switches, but lost in their product forest. I'm looked at Express 500, 2960 and 3750-E models. Is there any more difference (in exception of stacking, cli and hot-swap fan/psu) that I need to consider? Prices differentiate too much.
I'm also looked at Linksys/D-Link business products and they seems to have the same features as Cisco Express series, but only 50% cheaper.
I've a rack in the datacentre, and actually sharing the ethernet line with another partner's rack.
Something like:
Bandwidth -> Switch 1 -> Switch 2 (partner's rack)
Bandwidth -> Switch 1 -> Switch 3 (my rack)
After a previous uplinks issue, i'm never able to hit above 4Mbps of download speed to my home's cable broadband anymore. I have no idea whether it's because my partner capped my bandwidth from Switch 1, or his usage has increased such that it's affecting my traffic too. I can't be too concerned about it with him, as he's paying the bulk of the bandwidth costs.
For the whole rack, i'm not able to hit above 5Mbps accumulatively, and my normal bandwidth usage is only about 1-2Mbps.
So i'm thinking of getting another line for bandwidth directly from the datacentre to my Switch 3, perhaps starting from just 1-2Mbps only.
How will things improve? Just a silly thought, whether my total available bandwidth can now be 5Mbps + 2Mbps = 7Mbps.
We have a few CPanel servers, all with multiple NIC's. (2 Each)
We want to setup Eth0 to be the managment interface (ie. 72.2.24.x)
We want to setup Eth1 to be the Shared / Exclusive IP Nic (ie. 67.69.141.x)
Here is the issue, Eth1 is on a totally different Vlan than Eth0.. thus, isolating DDOS attacks, and any other type of traffic concerns for managment.. But, it also has a different G/W as Eth0.
We are in the process of buying a server to co-locate
All the server centre's we look at are trying to charge lots of money for firewalls
We have looked into renting and buying firewalls
but all the bought ones seem to be in the form of 1U
my question is this:
Is it possible to have a firewall that fits inside a 1U rack?
...something like a network card with an inbuilt firewall
does any hardware like this exist or will we need something that takes up a 1u space?
how can I change ethernet port speed. For example I want to change 100 mbit to 20 mbit. I m using centos 4.5 final.

I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts
I want to backup a entire folder thats in / not in any other folders.
I've tried this command but I get the error described below..
tar cvpzf opensim.tgz
tar: Cowardly refusing to create an empty archive
Try `tar --help' or `tar --usage' for more information.
The folder is called opensim. I was logged into SSH with root access and tried the command directly, not going into other folders because well I dont want to, I wanna backup that 1st opensim folder that I can see on the FTP also.
I'm having some trouble finding a VPS host that offers Debian and Plesk. I've searched the forum but nothing's really panned out. I'm currently with Geekstorage but the server has been slow (same problem reported by others).

Install Required software
NX server needs ssh and some libraries to run. These packages are normally not installed during the basic installation process.Use the following comamnd to install
#aptitude libstdc++2.10-glibc2.2 ssh
Install Free NX Server in Debian Etch
First you need to download the .deb packages using the follwoing commands
i did the three steps..
Now you need to install .deb packages in the following order this is very important
#dpkg -i nxclient_2.1.0-17_i386.deb
#dpkg -i nxnode_2.1.0-22_i386.deb
#dpkg -i nxserver_2.1.0-22_i386.deb
If you get any errors use the following comamnd to fix
#apt-get -f install
Now you need to make sure ssh and nx servers are running if not start with the following commands
#/etc/init.d/ssh start
#/etc/init.d/nxserver start
--------------------
but the problem is i cannot connect to the nx .
i installed the program on windows but what is the username and password should i use? i tried to use the root but it said that the user root cannot be used.
i have the vps with debian 3.1

I have just installed my vps with webmin on debian 5 and I need a guide to how to configure my system to use suphp, Ive googled it but not come back with any clear guide.
I better add Ive plunged in at the deepend and after the secuity breach at Vaserv, I can not take the easy option and install lxadmin any longer.
Which OS is better in security and easy to use for vps beginner:
CentOS™, Debian™, Ubuntu™, Fedora™, or Gentoo™.?
I'm leaning towards centos but am concerned that development priority in that distro will switch over from Xen to KVM as RHEL does. Which distro would you choose for dom0 and why?
View 3 Replies View RelatedFrom some weeks I try to have a secure install for my Debian. THis server will be a shared hosting host so need special security but I don't know how to do this.
My requirement are :
- Apache
- PHP (mod, not cgi)
Actually, users can navigate into my server by using phpshell script. And someone put lots of file into /tmp directory so I tri to secure all of that but don't find good tuto for that; do you know where can i have some?
And what about php using cron so execute with php-cli how to secure it?
where I can find a guide or how-to to hardening Debian Lenny web server (a xen vps one)?
