OpenSUSE Network :: How Does A Server Without A Dedicated Monitor Work
Mar 29, 2011
When you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.
I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?
I am trying to connect to my VNC Server from a Windows 7 Box running TightVNC:I've followed all the instructions on this page:[URL]And I changed my xstartup scripts:
/etc/sysconfig/vncservers # The VNCSERVERS variable is a list of display:user pairs. #
i have a script in /home/rpcaldeira/server.sh to start my source dedicated server. But i would like to start this on boot time. get this to start on boot time? I'm running openSuse 11.2 in Text Mode.
The Fedora 13 Visualization guide mentions the ability to use "shared physical device" to give virtual guest full access to a network device. Where can I find more info on setting this up. When installing my first guest, the drop down menu didn't supply this as an option. Eth0 and Eth1 were not selectable (e.g. grayed out).Is there a better section to ask KVM related question? If so, I'll move there.
I'm setting up my first KVM guest now, played aroudn with VMware briefly. I did spend a lot of time wtih VM on mainframes (yes, I'm old)... and from my research, KVM is "catching up" with what we could do in the old days.
After installing 11.4, I need to type in the command to update the firmware for a broadcom wifi adapter. Then I needed to reboot, twice, before the system knew to use the adapter (where the adapter wifi light goes from orange to blue).
Then I needed to add my wireless network and type in my key. But the key does not take. If I click on my wireless network icon, it just re-asks for the key and does not connect nor give any other message. Network icon continues to display no connection.
So I need to reboot again.
When the system starts again, the adapter is blue, I click on the icon for my wifi network and it connects without asking for my key and I can then set to start my wifi by default.
My workstation is on a network, let's say 10.100.0.0/24. I'm opening up an openVPN Tunnel to a test environment in my company, receiving a lot of routes to this network (address range 172.xx.yy.0). Everything is working fine so far. In this test environment I placed a number of virtual systems having their own private network (10.99.0.0/24). I have one machine in this virtual cluster which is able to forward incoming IP traffic to the others.
When I login to this gateway system, using the 172.xx.yy.zz address, I can logon to the others using the 10.99.aa.bb addresses. Fine so far. But I have to be able to call these machines with the 10.99.0.0/24 addresses from my laptop. So I tried to add a route like: route add -net 10.99.0.0 netmask 255.255.255.0 gw 172.xx.yy.zz
Unfortunately I received an error messages: SIOCADDRT: No such process
According to the entries in other forum articles (Google helps in most cases), I have to add a host route first: route add -host 172.xx.yy.zz gw 172.well.defined.dest
I currently want to set up a network with 2 Ubuntu servers (mail and web) in a DMZ in order to separate them from an internal network. I want to use a dedicated Linux firewall. This firewall will have 3 network interfaces on it. One network interface will connect to the external router/modem (router and modem in one box), one interface will connect to the DMZ and the other interface will connect to the internal network. The router/modem lets you put, I think it's 1 or 2, interfaces in a DMZ.
But, when I think of any of the dedicated firewall's or servers' interfaces it doesn't make sense to me to put any of them in the router/modem's DMZ (I think it would be better for the dedicated firewall's and the servers' interfaces to have static private I.Ps ie 192.168.2.4 etc right?). What I mean is that even if, as far as the router/modem is concerned, none of the interfaces were in a DMZ, the area where the servers are would still effectively be a perimeter network and with such a set up would still be, effectively,a DMZ, right?
How to setup Dedicated Server for Web Hosting using Ubuntu Server or equivalent opensource Operating System? And how to make secured my Dedicated Server on public?
I am trying to setup a sendmail server on my dedicated server. It was pre-configured to use exim from cpanel. Is it possible to use exim for all emails from a a certain domain i setup on the server and sendmail for others?
ex. domain1.com -> exim domain2.com -> sendmail
If it is possible can someone let me know how i would go about doing this? If it is not how would i disable exim and use sendmail for all mail?
I want to rent a (root) linux server to run a vpn service on it. I want to allow people to use this vpn.
My questions are as follows: - What kind of server/service should I rent - dedicated or vps? - Is one IP-Address enough to connect, say, 100 user? (I plan to run IPsec or OpenVPN, maybe PPTP) - What Bandwith and/or traffic limits I need to consider to make the service reasonably fast for the users? - Which Linux-distro should I use? Ubuntu Server, CentOS, FreeBSD, Debian etc? - How much RAM and HDD space is recommended for such an endevour? - Any advice on the processor type the server should have? - Is 100M network ok or better 1000M? - What means 100Mbps shared bandwidth in contrast to 10Mbps dedicated guaranteed per server?
Can anyone walk me through the process of increasing my max connection on my linux server?Over the last few weeks I have been getting errors saying I have to many connections.I think the default is 100 and I would like to maybe increase it to 150 or 200I know I cannot go to high because I will then be using to much of my memory or maybe CPU
The /var directory is 97% full on my dedicated server:
I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).
I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.
I have Putty Access to root but do not know which command to use.
I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.
My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.
I have only a very basic understanding of command line but really need to get this sorted ASAP.

Is it possible and SAFE to delete files via FTP from the /var/cache/apt/archives?
I am using orion snmp monitor in my network and I have no problem with windows systems but linux systems have some problem first of all snmp monitor shows cpu load on 100% all the time that is completely wrong and secong my snmp monitor can just show cpu and memory and response time information of linux systems and not disk information and nothing more. this is my /etc/snmp/snmpd.conf file content:
com2sec paranoid default public group MyROSystem v1 paranoid group MyROSystem v2c paranoid group MyROSystem usm paranoid group MyROGroup v1 readonly
I broke my apache server. I went into the Yast administrator / HTTP Server and enabled the "rewrite" module. The server stopped working so I went back in and disabled it. Now the server still doesn't work and when I try browsing to any of the sites on it all I see is a page that says "No database selected" for any sites using databases. For static sites I get a 404 error. I broke rule #1 and didn't have back-up configuration files so now I'm stuck. What could the Yast module have done to my configuration files? I have restarted apache several times and even re-booted the computer.
I am using Open Suse 11.2 on my HP DV6 notebook. I am connecting my television to the notebook with a HDMI cable and the television is unable to find any signal. Am I missing anything here? Shouldn't it be simply connecting the HDMI cable finding the source channel on the television and then I get sound and picture..
I was unable to access my dedicated server for few minutes. I have checked the apache error logs and found below notice: [notice] caught SIGTERM, shutting down I have tried to search from Google but could not find much information about this error.
I want to install Webmin on a dedicated remote server. I keep reading different blogs/tutorials etc about installing webmin on Ubunto server 10.10 but it seems too easy to be true. There is never any mention of requirements etc. I did read that even perl isn't needed pre install now and will install with webmin.But do i need to install lamp etc first or does it pull these in when Webmin its installed?
I have a server running slackware 13.1, and it is running windows server 2003 with QEMU-KVM. I followed [URL , now two system can connect each other.
The problem is: I bought two dedicated IPs, and I wanna know how to setup these two system to be Internet Servers.(Nginx in slackware, IIS in 2003) I found some subjects but I can't find what I want.
We have a quad core Intel Xeon E 5410 processor running on recently installed centOS 5.5. Machine can't be pinged all of sudden and when we switch on the monitor, no signal on it, even no response on keyboard. We thought the problem accorded with abrupt temperature changes, is it so? But we have similar machines running efficiently under same temperature conditions.
There is no "security" forum so I figured I'd post this here.
Because of PCI compliance requirements, we are going to begin using the built-in audit utility that comes with SuSE to monitor file/directory changes. The utility comes pre-configured to monitor many system files but I was curious as if there is a standard list of files/folders that should be monitored for PCI compliance? I've scanned the web but haven't come across anything yet.
I have set up a Virtual machine on a dedicated server from 1and1. I hoped to use a bridge to give the vm direct access to the internet but 1and1 do mac filtering and so the only option is to use NAT.
I used Virtual Machine Manager on my Ubuntu 10.04 machine at home to install Debain Lenny on the vm on the server using KVM and all went well. I put it on a virtual network 192.168.100.0 and i can access it from the host and i can access the internet from the guest using NAT that libvirt set-up.
I bought another ip address from 1and1 with the hope of forwarding packets to the new ip address 11.22.33.02 to the guest vm.
I have tried all sorts of routing rules using iptables without any success.
my virtual network is on virbr1 the guest ip is 192.168.100.50 my external network device is ip say 11.22.33.01 on eth0 with the secondary ip say 11.22.33.02 on eth0:1
Here are the latest rules i tried:
Quote:
iptables -t nat -A PREROUTING -d 11.22.33.02 -i eth0 -j DNAT --to-destination 192.168.100.50 iptables -t nat -A POSTROUTING -s 192.168.100.50 -o eth0 -j SNAT --to-source 11.22.33.02 iptables -A FORWARD -p tcp -i eth0 -o virbr1 -d 192.168.100.50 -m state --state NEW -j ACCEPT iptables -A FORWARD -t filter -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
I'm wondering a couple of things about my LAMP stacks:
1) How do I get a list of all the network cards installed in a linux box? I've run this command and it shows 2 network cards which is probably all of them: Code: mii-tool -v
2) How can I check the percent utilization of a given network card? I.e., at any given time, what linux command will tell me the how much of a network card's bandwidth is being consumed? I've checked both ethtool and mii-tool and I don't really see any helpful stats.
3) How can I make sure that a linux box will optimally use both network cards? I'm a bit fuzzy on how IP addresses and network cards and hostnames work together.
I need a software to monitor all USB activities over the network from a red hat server with alert notification i have searched a lot and never found a thing
In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.
As a consequence all network services are not working. I can't connect to any other machine nor to the internet.
I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.
Any suggestions how to make it work again? I'm using Suse 11.3.
