Networking :: Hide The IP Of Y Server Want X Server To Be As VNC Proxy And Redirect All VNC Sessions To Y Server
Aug 21, 2010I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so
Server :: Server Configuration For Small Office Server, Which Smtp, Pop Imap Server And Backup?
Apr 2, 2010I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
Networking :: Bonded NICs At Host OS - Ubuntu Server - Bridged To Virtual OS - UServ - In VMware Server
Jul 19, 2009Just something that struck me while working on our virtual servers today.
I have bonded 3 NICs at the host in Ubuntu Server 8.04 LTS. They are using mode 0 for Round-robin. Point is to increase the speed/performance of all the servers, but mainly the fileserver. The fileserver is a virtual server running Ubuntu Server 8.04 LTS on VMware Server 2.0.
1) I noticed the NIC in the slave OS reported link speed as 1000 and Im unable to change it as the NIC (virtual one) doesnt support it. Does this not really matter, as the NIC doesnt exist, and it will run at higher speeds anyway? Or do I have to remove the bond on the host, bridge all 3 interfaces from the host to the slave OS, and then make a bond in the slave OS?
2) While at it, does mode 0 only increase performance on data being sent from the host or does it also increase the available incoming bandwidth?

Ubuntu Networking :: Error - Cannot Connect To Server - You Must Enter A Name For The Server
Apr 17, 2011In Gnome Places->Connect To Server dialog, I am having problem using the Custom Location Service Type. I enter in the URI as
Code:
smb://username:password@ipaddress/share_name
I get an pop up error message that says:
Quote:
Cannot Connect To Server. You must enter a name for the server.
Which would be fine if there was actually a place for me to enter the name which there is not. What am I doing wrong. This is the first time I have tried using the Connect To Server dialog. Normally I just use a script I wrote to mount my share in a folder on my local drive as some programs cannot access the mounted network folder. In a browser all I have to do is:
Code:
smb://ipaddress/share_name
I tried using Windows Shares, but that did not work either. It does work if I click on network and access the share that way, but some programs like firefox and a few others that I want to save a file to my network drive do not show the network unless the share is mounted in a folder. So, I wrote a script:
Code:
#!/bin/sh
#mount ext storage drive
mount -t cifs //192.168.0.2/files -o username="username",password="password" /mnt/files
This works and I can use this, but it would be handy if I could just use the Connect To Server dialog.
Ubuntu Networking :: Setup A Server 10.04 Lts As File Server?
Apr 3, 2011I set up a ubuntu server 10.04 lts as file server in a network filled with xp, win 2003 and win 2008.
I noticed that if from any bill's SO machine i copy a file (for example a vob file of 1gb, or a lot of doc and pdf files) in the samba server, while the copy is in progress if in another windows I browse other folders shared in Samba, the copy process stops and say ' the name in the network is no more available( or something like this). It seems that samba pay attention on the fact that a user is browsing the share and doing so it seems that Samba forget that in one of its share there was a copy in progress, very annoing. A file server cannot do that, in this way is useless.
Networking :: Server On Multiple VLANs Server Not Responding To Pings From Non-local Subnets?
Jul 14, 2010I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Networking :: Pug Server File Server No Longer Shares Drive To Windows?
Nov 19, 2009My Pug Server has worked faithfully for many years just sitting in a closet. It is designed wo that you never need to add a monitor or keyboard as it is administered through a web interface. Recently it had a problem with the motherboard and I had to replace it, but the machine is now working. However, it no longer is visible as a network drive on my Windows machine.Unfortunately I have no idea where to start looking to see what the problem is. I did attach a keyboard and monitor and logged on, but everything looks okay (I can see my files, etc.).
This is an old machine (c. 2003), so has an old version of Linux (I have no idea what version, or even how to find out). Since it is never meant to be used directly it doesn't have any GUI installed, so I have to do everything using command line.Does anyone have any suggestions as to how I can even start to determine what the problem is or how I can go about trying to fix it? At this point I would be happy just to get the files out and replace it with a newer NAS.

Aug 10, 2010I have a OpenSUSE 10.1 system on my college network and I am able to ssh to other college servers, but I cannot ping these servers. More importantly than pinging when I try install one particular program it needs to be able to access one of the college servers (which has the license for it) but it is not able to contact the server.I have installed this program on other computers (windows and redhat linux) on the college network and they can connect to the server (and they can also ping the server).But Idon't know how to fix this problem.I have googled lots of things but I am a bit bamboozled.I have turned off the firewall but it doesn't make a difference.
View 2 Replies View RelatedServer :: Server Networking Suddenly Flaky?
Aug 24, 2010I've had a server running for over a year and it's been very stable. Suddenly (no config or software changes) it's behaving oddly. If I perform a network related activity, it appears to effect other separate network functions. Example: I get onto the machine using realvnc server and suddenly port 80 goes down, or I can access port 443 inside the network but not externally, or I can get to 443 but not 80. The server has two network cards. Switching to the second card appears to have had no effect. I also tried rebooting, switching in a new network cable, bouncing the network card (which does re-establish services, but not consistently). I have several servers and this is the only one misbehaving. It's running Debian Etch (as are a few others).

View 14 Replies View RelatedDebian Configuration :: Install A Multi-core System And Configure It To Run Several VMs, One Each For A Firewall, A Caching Proxy Server, A Mail Server, A Web Server?
Jan 25, 2011I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
Server :: Configure Internal Zimbra Server To Use External Server To Send Mails?
Feb 16, 2010I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?
