Ubuntu Servers :: MySql Connection Delay With Windows Machines?
Mar 9, 2011
At first I thought the Delay was normal. After looking around it seems that it's not true. I made a post here. The Problem seems to be related to DNS.
The Server in Question is not Online (as in on the web), all machines are on local ethernet. From What I understand DNS is to mask the IP like a named variable for each IP. I am still figuring out the ins and outs of a linux server. DNS is something I have little or no grasp over. So I need help in setting up the DNS for this scenario case. All guides I have seen seem to be for web servers which is where I stop reading and look for other guides. I have webmin and Bind9 installed on the server.

We got a new server with 2 network interface cards with 4 MAC addresses in total. We would like to run two virtual machines (vserver1 and vserver2); one should connect via eth1, the other via eth2, and the host (mainserver) via eth0. The content of /etc/network/interfaces is as follows:
[Code]....
A connection from mainserver to vserver1 or vserver2 is not possible; a ssh connection from mainserver to vserverx ends with a login to mainserver.

Having finally got Samba shares and printer shares working on my Lucid Lynx server, I've noticed that the throughput from/to those shares is very slow to what I was used to when I had those shares on a W2K server.Having Googled this problem, I noted that there was a known issue with this in Karmic (believe Brian Wu was looking at it). However, I don't see any results in Google as to this being a problem in Lucid.
I know ipv6 can cause a problem in this regard but having issued the command:
lsmod | grep inet6
I know that ipv6 is indeed disabled on my Lucid server. Any further information on whether the error reported in Karmic still applies in Lucid, and can this be addressed in any way?

i manged to get a samba server up and running to share with my windows machines. But i still want more. My main goal is to be able to share my movies. I have a laptop hooked to my flat screen with 3TB's of external drives, thats whats acting as my server. I have ubuntu desktop installed because i use it to play movies also.
I'm looking to set up something that is a little faster than samba (yes i no trying to share through USB 2.0 external drives and a wifi connection isn't going to be real fast no matter what) but i want to be able to access my server remotely. like maybe FTP? but what i'm asking here is what protocol should i use and what programs? i was thinking gadmin-proftpd and then filezilla to access?

Im an IT manager for a small company with a small ammount of users. We already use linux for our data server and I would like to implement a domain controller. All of our user machines are WIndows XP pro.
Ive been reading up on using OpenLDAP as an alternative to active directory.
What I want is just a simple active directory like server, with a GUI if possible.
What do I need to look at and how would I go about setting this up? Im fairly proficient with Ubuntu already, I just need to be pointed in the right direction.
Is it even possible to have my windows users be able to log in to their machines using an ubuntu domain controller?

I am facing some strange problem of mysql replication with ssl, my replications which working fine from more than 6 months currently stopped working after i upgrade mysql in to newver version mysql-5.1.41-2, i create new ssl self singed certs but still no sucess, when client try to connect the master using ssl its gives error SSL connection error ERROR 2026 (HY000), with out ssl its working f9.
Platform --> Fedora-11 + mysql-5.1.41-2 (both master/client)
I can seeking the problem on net, and i found the below bugzilla url related to that.
[url]
I read it but not get , either new version support x509 ssl certs or not or either new version support ssl replication or not, here below my server configuration for ssl serts
And for client
Both server and clients certs are signed with same ca but still its currently not working after the mysql upgrade first 5.1.41 and then 5.1.41-2
Either as above bugzilla url, currently mysql support ssl replication or not, or either some need to do special for working with ssl. or i wait for newver version of mysql to fix if its bug or not.

My problem is that every time I use the Ethernet connection (I don't have wireless card) there is a delay of around 30s, even though my download speed is not affected at all once the connection is "established" , no matter what application I use (Synaptic, ssh, firefox, google chrome,wget, update manager, etc.). A weird thing is that my ethernet connection always appears as active.
I'm sure I'm not the only one who has experienced this issue, since I've read the same problem on other forums, but no one has come up with a solution. I hope that there will be a solution at last by this time.
I've been around with this problem for about 1 month, I've tried all sorts of tweaks that involve disabling ipv6 and nothing happens. I don't really know what triggered off this issue because it all started all of a sudden and I don't remember having installed any important update by the time this happened (I did a clean installation of Ubuntu 10.04 32bits on the release date).

I am looking for a version of vmware that manages 2 severs at the same time and that mirrors them such that if one goes down we can still work on the second and of course it also works as a backup. Also, must work on a ubuntu server I have looked but there are so many version that I don't know which one is the best.

After GRUB 2 comes up (I'm running Ubuntu 10.10) and I choose the OS to boot, there is about a 5 second delay where nothing appears to happen after I make the selection -- no disk activity. It happens consistently every time I boot. Again, this is after I choose the OS to boot, so it shouldn't have anything to do with the standard delay to allow me to choose the appropriate OS.Is there a good way to troubleshoot this and determine what is causing the delay?

I downloaded the ubuntu server (command line only) iso and set up a server on a spare computer. The only partition is ubuntu. LAMP server installed, and runs. Its plugged into my home network and the router assigns it a DMZ. I use ptty and that allows me to connect the server from my Windows PC. I installed samba and that works, I set up the server as Z: to my windows PC, and I can now use Filezilla FTP to move gigs of files over from my windows PC to the ubuntu server. I have to log in to activate the connection to Z: but it works.
Problem is getting a database connection from my windows PC (client) to my ubuntu server. Server is running a MySQL server and an Apache Derby server but both give connection:refused every time I try to connect with a java app, or with ij from my client. I tried MySQL Workbench, as that has a GUI, that doesnt connect to MySQL either. Every time I start my server I have to add lots of jar files to the CLASSPATH just to get the Derby server running. The Derby client connection on my client PC is also properly set up with PATH and CLASSPATH etc etc all configured and tested. But the server refuses every attempt to connect even though it tells you the Derby server is up and runnign as listening on port 1527!!!
What I want is a script or app that will "unlock" my server so I can actually do something with it instead of constantly trying new settings and packages in the vain hope it will then actually 'serve'. I am missing something here. There is nothing of value on this server that cannot be 'exposed' to the internet, so I'd be happy to turn off all the security just so the damn thing allowed connections...!

Problem started after installing a new firewall in my network. originally after installing the firewall there would be a 10 second delay after entering a command before it was processed, the command would be executed however there would be an error, i forget what it said, something about not being able to resolve my domain name (and it would give my domain name). i realized this was a problem with my NAT, so i configured DNS forwarding on my firewall so that any attempt to access my server using my domain name from inside the network would point back at my server. after setting up the DNS forwarding i no longer receive the error about my domain name being unreachable, however there is approximately a 30s delay between entering a command and its execution.
the problem is hardly critical i do not see any more serious problems, it is just a pain to do any work when every time i try to do something i have to wait for it to execute.

Every time I attempt to restore, maximize or resize a window, there's a noticeable delay (a couple of seconds) before it happens. This doesn't happen with desktop effects turned off, so I figured it's somehow related to compiz. However, I have no idea what it is..

I've set up a cups printing server using ubuntu 10.04.1 LTS. The printer's a HP Laser Jet 1018 I can connect to it over vpn using openvpn from my netbook which is also running ubuntu 10.04.1. I can connect to the printer all right and test page prints without a problem. But if I try to print anything else, it take at least 5 minutes before the job is successfully send and printed out.
Also, on the client side, for example, the file size would like 500k, and when it finally prints out, the file size on the server side is less than 10k. The file is a black and white document, and from what I can tell, the printed page is not missing any information.

I tried to create trusted connection between two machines (named "master" and "node1") for shared account, but no luck. what I had done are as follows:
1.create user account "tester" in "master"
2.set NFS server configuration to have RW for /home/tester for "node1"
3.create user account "tester" without creating home dir in "node1" with same userID and groupID as the one in "master"
4.create dir "homester" in "node1" and mount to "master" (mount -t nfs master:/home/tester /home/tester).in master node: ssh-keygen -t rsa
5.generate authorized_keys in "node1" (details not shown)
but it is not working, if I don't use home/tester as shared dir, and two machines have their own /home/tester , the trusted connection gets created and scp works fine. can we create trusted connection for shared account, if yes, how and did I do miss anything.

I've got a few parts laying around and maybe a 100 bucks on NewEgg I can get a Windows Server going. However, I have a few questions. I already have two Ubuntu servers going. My main concern is OS updates. I have Ubuntu based distros covered via apt-cacher-ng on one of my Ubuntu servers. I also have a nice squid server going with adzapper and so on. However, I have a bunch of Windows based machines on my network, and I have very limited bandwidth. I know I can run a virtual server on my main server, but I prefer to have an actual box just for a WSUS server for personal reasons. This is only an option if there is no option for WSUS style updating through Linux on my current server.
If I have to build a low powered Windows Server box in order to just push Windows updates for XP, Vista, and 7 to save bandwidth in the long run will a copy of Windows Home Server do the trick? I read an article from MaximumPC that WHS 2.0 will have a WSUS feature, but is this feature available in WHS 1.0? This is a really crappy way of storing updates and save bandwidth, but I don't know what other options I have. I live and work in a very remote area and I've already done everything I can think of to help save bandwidth. Like having a transparent proxy server and apt-cacher-ng running. It's also helps run things a lot faster when updating Ubuntu based boxes and surfing the internet. If I could just get the Windows updates out of the way I would be golden. I'll wait for WHS 2.0 if I have to. I'm not buying a full blown copy of Windows Server just for updates, especially on a box that'll cost about 300 bucks when complete. Still better than a prebuilt WHS box advertised on NewEgg for 600 bucks.

Using gnome I love the desktop effects, except the 'maximize window' effect. There is an annoying delay when I maximize a window. Is there a way to turn this particular effect off, while leaving all the others on. I looked in control center>desktop effects, but the option is not there. The only way I could turn off the maximize effect was unchecking the "enable desktop effects" checkbox. But this turns all effects off. All other effects run smooth and snappy.
