Ubuntu Servers :: Dynamic VLAN's - VMPS - Where To Start To Get This Configured
May 11, 2011
Basically im trying to setup a dynamic vlan setup with my Cisco 2950 switch. I understand that freeradius has support for vmps and i'm wanting to use this. (as i'd also use the radius server for authentication for my squid proxy server)
But i have no idea where to start to get this configured. Right now i've got the freeradius package installed and i've done a bit of google'ing and i cant seem to find much about vmps and freeradius.
Looking for any help I can get here.. We have a 9.10 server with both (ifenslave & VLAN) installed and configured. When we are running in bond mode (bond0) it sets the MTU to 9000 just fine.
Yesterday, I tried to get two monitors working by editing xorg.conf. When it failed, I tried using my old xorg.conf, but that didn't work either. dpkg-reconfigure xserver-xorg did not work (it literally did nothing). Uninstalling and re-installing xserver-xorg did not work.So now I have zero working monitors instead of two. Xorg.0.log says something about "Screen was found, but doesn't work with existing setup." Anyway, I am less concern with the specific problem I am having than with the general way to fix problems with X. I read somewhere that dpkg-reconfigure xserver-xorg doesn't work anymore, but I haven't figured out what I'm supposed to use in place of it when X won't start.
I have been wanting conky to run at start up... fortunately I got that part done (I am very new) but after that, even though my conky was not configured to stand on top of my applications it would, and I didn't want that so I added some more code, and now it disappears if I click over it, it is still running, just not visible.
I need to obtain daily dynamic IP address from my router for remote user. In order to get into the router page, I need to login to it with ID and password.
Can I tell the server to do this every time it started up to login to router and extract the ip address and send out via email?
The router can only access through web interface and below is what I copied from browser.
I just install a new server and I would like to now what are the basics that I should install. It currently has LAMP stuff. Any one know how are the VPS server configured at hostgator.com and similar web hosting platforms.
I want to restrict the Visitors to my Webserver whom i want to give access But the persons whom i want to give access. have Dynamic IP. I want to use DynDNS and update IP address of person. Based on the Hostname Pointing to Dynamic address of person.
As far as I can tell, the server guides only explain a bit about what dynamic routing is, but not how to implement it.
My situation is this:
We require a server with 3 interfaces. One local, one to a vsat link and the other to a fibre link. The fibre will be the default route for Internet traffic but we want dynamic routing to automatically switch to the vsat link when the fibre link goes down (which happens fairly often in Zimbabwe!) and then switch back to the fibre link when it comes back up again.
The first option would be to handle dynamic routing on a Cisco router, but at the prices of Cisco devices here, it's not the most affordable option.
I have this strange problem which I am unable to web search on and not sure what to do next. My Linux knowledge is between basic to intermediate but I know how to troubleshoot general hardware problems.
My problem is that Ubuntu 9.04 Jaunty 64-bit hangs while SFTP is active and dynamic IP changes. For example, I SFTP into my home server and transfer file then suddenly my ISP decides to renew my IP and give me a new IP while my SFTP client is still uploading files to my home server. This causes my SFTP client to stop working. Upon checking, my router is still running with a new IP lease from my ISP. My Linux box still powers on but typing anything from the keyboard does not make it "wake up" and put things on the monitor. Nothing seems to make it respond and the only way is to get about it is to power off and on. During that time, you cannot SSH into the server as there is no respond. SFTP into the server is not possible too because connection fails.
The server has all new hardware, latest BIOS, etc. Memtest86 shows no errors after running for more then 5 hours. I am unable to find anything out of the norm in /var/log/kern.log or in dmesg. All hardware seems to be working.
When I think about it, I tend to think OpenSSH (probably that is the default package in Jaunty) is causing this system hang whenever there is an interrupted connection from the outside world. However, I fail to agree with this is because I am sure the daemon and Linux can tolerate this situation without resorting to system hang. FYI, I have installed vsftp as well but this should not be a problem.
I have 4 servers that I got at auction and they now have ubuntu running with gnome interface.I installed apache2 and tried to edit the conf file but i am not sure if it is a router issue a dns or the config.I am trying to figure out how to set the server to hold the domain from a dynamic ip address and also how to create some test page to see if i can acess from the internet.
I have purchased some books on the command lines and how ubuntu works, I am understanding it so far, but dont know how to have a directory for the dns request to point to for the sitewhat i want to do with the servers...voipeb server for about 4 websites - one is for a volunteer rescue organization, another for a test auction site and 2 portfolio sitesremote file access- if possiblealso on a side note, is it possible to have a message relay from one cell phone or transmit to the server and have it send sms message to cell phones? - this will be used for the rescue group as well.
For backup and pre-functionality purposes, I need to simulate a VirtualHost in my Fedora (14) machine. I found some interesting links to carry out that process but with an IP fix.So, how can I simulate a VH through a localhost with a dynamic IP?
I am having trouble with setting up BIND9 for 6 virtual servers that use ubuntu x64 v10.10. I have main server running ubuntu as well. host name is xeonserver I would like to explain my setup first.
my router ip: 192.168.1.1/24 host server for VMs ip: 192.168.1.2/24 Then on qemu my virtual machines are in 10.0.0.0/24 network, gateway to my router is 10.0.0.1
1. kerberos.xeonserver (not configured yet) 10.0.0.2 2. dns.xeonserver (the one I have trouble with) 10.0.0.3 3. mysql.xeonserver (not configured yet) 10.0.0.4 4. apache.xeonserver (not configured yet) 10.0.0.5 5. ftp.xeonserver (not configured yet) 10.0.0.6 6. mail.xeonserver (not configured yet) 10.0.0.7
To configure it I followed instructions found on [URL]
i want to set up an email server both to receive and send emails. I also am on a dynamic ip scheme with my ISP. I do have a dynamic dns account with no-ip.org the Questions are:
-will somebody be able to send emails to me at the <user>@<dyndns_name>.no-ip.org email address?
-will I be able to send emails from the <user>@<dyndns_name>.no-ip.org email address?
I know i'll be able to login to accounts like gmail and yahoo and download emails from there.. but even that i don't know - even macroscopically how its done:
-is it the sendmail deamon that accepts the mail from <me>@gmail.com, <me>@yahoo.com, <me>@<dyndns_name>.no-ip.org?
-is it the sendmail deamon that does the sending of email (as well)?
-can it push emails that I want to send as <me>@gmail.com to the gmail smtp servers (and they in turn will push my email even further)?
-can it push emails from <me>@<dyndns_name>.no-ip.org to receipients? and finally,
-WILL receiving pop/imap servers allow incoming email from my server? or due to the dynamic ip they'll assume I'm a spam server?
My problem is configure and start FTP server on own computer. I edited configure files, and i try to run ProFTP. Then i see that communication: Launch proftpd: - warning: unable to determine IP address of 'dhcppc1'
Tomcat6 is built in server with it but i dont know how to use it .I am doing a dynamic web project based on servlet and eclipse galileo is being used as IDE for it.
The problem is that I have set up a test installation with DHCP server and DNS server on Fedora 14 and want to set up dynamic updates from the DHCPD to the NAMED. The problem is that any attempts to make updates of the DNS server fails with a "SERVFAIL" error. I can not even update it through the NSUPDATE tool. This is NAMED.CONF:
After upgrading my server from 10.04 to 10.10 I keep getting the following php error, "PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/syck.so' - /usr/lib/php5/20090626+lfs/syck.so: cannot open shared object file: No such file or directory in Unknown on line 0"
I have a mysql database and i use it with apache for my webpages. And I guess it dosen't start when the computer starts so I have to manually start it with "sudo /etc/init.d/mysql start" This returns fail so i went to '/var/run/mysqld/' and the folder was empty. I don't know if this is the problem or not. How can I fix this?
I have a RedHat box that I have configured, security, audit rules, latest updates, etc. I want to be able to "image" that configuration so I can kick other boxes with that "image", that way no other configuration/updating needs to be done on the newly kicked boxes. What is the best way to accomplish this? To make things more difficult, it would be near to impossible for me to pull any software off the internet for this.
the problem is that with the above configuration, i connected 3 linux boxes on the switch but non of them could connect with each other. when i did a ping, it says "destination unreachable"
what am i missing out here, and whats the fix?
i assigned static ip address to these boxes, also there's no router in this network by the way. i dont think i will need one either as all the machines in in the same vlan2.
I'm preparing to "follow" these directions which will make VirtualBox's networking behave like VMWare's "NAT" networking. Of course, these instructions are for a Ubuntu/Debian setup.
I am quite certain that I can write a script that'll do the equivalent steps on my Fedora 11 box -- which is acceptable to me. I would, however, like to know how to splice this stuff into NetworkManager and/or /etc/sysconfig/networking/devices/, to do this the "right" way.
The desired networking behavior: -VM's get assigned addresses via DHCP on a virtual network -VM's can talk to each other and to their physical host -VM traffic out to the 'real world' is NATted
i have configured transparent squid with dansguardian for content filtering i used this squid server ip on client gateway(not on browser) for content filtering, is it possible that i could use this squid server in different VLAN.
I am trying to provide dynamic IP addresses for devices that are on a different VLAN (101). The server is currently providing 172.17.x.x/16 range for its own VLAN (417). My server is RHEL4 and DHCPD is version 3.0.1. The core switch (Cisco 3750) is configured with ip-helper on VLAN 101 interfacce. Here is my dhcpd.conf file:
I'm trying to setup a Asterisk box with two NIC's. The idea is that one NIC connects to the LAN on VLAN2 (for internal voice) and the other to the SIP trunk on my ISP's Cisco 1811, configured for VLAN3.
Some info: The Cisco's VLAN1 + 2 are available on my switch. VLAN1 = 10.105.44.x with gateway .254 (the Cisco). VLAN2 = 10.106.45.x with gateway .254 (the Cisco). The Cisco's VLAN3 is available on only a single port on de Cisco, connected to one of de NIC's of the Asterisk box, eth1, with IP 10.106.46.1 and gateway .254 (the Cisco). The other NIC, eth0, is connected to the switch, on a port setup for VLAN2.
So, what I'm trying to achieve: Use eth1 tagged with VLAN3 to connect to the SIP trunk. (I could do this with a static route because my provider has a fixed IP to connect to) Use eth0 for all other traffic.
Here are some config files I've setup so far (I'm stuck on connecting to the SIP provider):
I just have installed FC 10 on a box that I will use as a router/firewall box. On the box I have three interfaces (eth0, eth0.704 (VLAN), and eth1). When the machine boots up, only eth0 and eth1 come up. If I run /etc/init.d/network restart, then eth0.704 will come up. If I add that command to rc.local, then all interfaces come up at boot.
I have the directive ONBOOT=yes in ifcfg-eth0.704. What would cause this vlan interface not to start at boot on the machine?
