I am not able to connect remotely on port 3306. My hosting company says that i have to allow connection on port 3306 using iptables.
Whats the command to type on terminal
I've been trying to get some information about the MAPI plugin for Evolution - but it all seems to in pieces everywhere, and also mostly a couple of years old.
Anyone had any experience with getting Evolution connecting to MS Exchange via MAPI? Unfortunately, any other connection method (IMAP or WebDAV) is not an option - either because of not being allowed or just unusable.
If I have
>ip ro
192.168.14.0/24 dev eth0
another host can obtain my mac address. But if I flush routing info:
>ip ro flush table main
arp resolution doesn't work. Broadcast packets "Who has 192.168.14.149" reach eth0 but OS (Linux) doesn't respond despite eth0 has address 192.168.14.149. What connection exists between routing and arp resolution?
Hi below is some code I added to my .htaccess code how can I add certain pages to be re-directed to https? such as login.php & login.html
also if the user types in www. they get a "untrusted connection" as the SSL is only valid without the www. how could I fix this?
Thanks
RewriteEngine On

Using the Launchpad from the Mac, trying to connect to Server Essentials 2011, no one is able to actually log in. The little login wheel keeps spinning and spinning. Anyone have any ideas what might be keeping us from logging in? On the mac side, we are using 10.6 and 10.7, but both are exhibiting the same problem. I also cannot connect to the server by remote desktop connection within the local network.
HELP!
We have been running nginx - uWSGI, and now we are evaluating putting
Varnish as a caching layer between nginx and uWSGI (similar to
http://www.heroku.com/how/architecture).
But, nginx only supports HTTP 1.0 on the back so it will have to create new connections with Varnish for each request.
Many recommend running nginx in front of Varnish, but wouldn't it make much more sense to use something like Cherokee so that you eliminate the HTTP connection overhead since it supports HTTP 1.1 on the back?
I have the SSH connection working. I have it successfully modeling the device (Ubuntu Server, in this case).
What I can't get to work is the SNMP portion. It sounds like I have to custom add the snmpwalk command when doing monitoring over SSH - in other words, have Zenoss connect via SSH, and then run an arbitrary command agains the client (in this case, an snmpwalk), and then parse the results.
What I need help doing is:
Add the snmpwalk command to the SSH monitoring
Parsing the output and getting the data back into the charts
There's so much bloat and extras installed, and I just want a clean install. I've got REVO but I'm hesitating over what stuff I can remove without it crashing on me, or losing Internet connection...
Links, ideas, experience always appreciated
Thanks
Mike

I fell into a snare when i downloaded and install virtual box 4.0 on my ubuntu 10.4, when i started the virtualbox i tried i saw that my network icon on my desktop showed my red x showing iam disconnected and this happened shortily when i installed virtual box 4.0
I have searched through the web and found some people who have faced some problem. but the solution they gave them i tried but it coudn't work, of restarting,starting ,stoping the netowrk manager, i was even thinking of uninstalling this virutalbox but not netowrk connection
truely i need your help

Topology overview
Host A has a single NIC.
Host B has four NICs which are bonded using the balance-alb mode.
Both hosts run RHEL 6.0, and both are on the same IPv4 subnet.
Traffic analysis
Host A is sending data to Host B using some SQL database application.
Traffic from Host A to Host B: The source int/MAC is eth0/AA:AA:AA:AA:AA:AA, the destination int/MAC is eth5/B5:B5:B5:B5:B5:B5.
Traffic from Host B to Host A: The source int/MAC is eth0/B0:B0:B0:B0:B0:B0, the destination int/MAC is eth0/AA:AA:AA:AA:AA:AA.
Once the TCP connection has been established, Host B sends no further frames out eth5.
The MAC address of eth5 expires from the bridge tables of both Switch 1 & Switch 2.
Switch 1 continues to receive frames from Host A which are destined for B5:B5:B5:B5:B5:B5.
Because Switch 1 and Switch 2 no longer have bridge table entries for B5:B5:B5:B5:B5:B5, they flood the frames out all ports on the same VLAN (except for the one it came in on, of course).
Reproduce
If you ping Host B from a workstation which is connected to either Switch 1 or 2, B5:B5:B5:B5:B5:B5 re-enters the bridge tables and the flooding stops.
After five minutes (the default bridge table timeout), flooding resumes.
Question
It is clear that on Host B, frames arrive on eth5 and exit out eth0. This seems ok as that's what the Linux bonding algorithm is designed to do - balance incoming and outgoing traffic. But since the switch stops receiving frames with the source MAC of eth5, it gets timed out of the bridge table, resulting in flooding.
Is this normal? Why aren't any more frames originating from eth5? Is it because there is simply no other traffic going on (the only connection is a single large data transfer from Host A)?
I've researched this for a long time and haven't found an answer. Documentation states that no switch changes are necessary when using mode 6 of the Linux interface bonding (balance-alb). Is this behavior occurring because Host B doesn't send any further packets out of eth5, whereas in normal circumstances it's expected that it would? One solution is to setup a cron job which pings Host B to keep the bridge table entries from timing out, but that seems like a dirty hack.
I connect to a remote machine from the local machine and use virsh console to enter the virtual machine. I don't know how to exactly depict how it works. Normally it works well, but when I run VIM:
Then it can't be recovered unless I cut the connection up:
It's very hard to work with a broken terminal. Any advice? My terminal works well on my local machine and the remote machine in which the virtual machine runs.
How can I hide my network connections (the PC with the red X icon on the task bar) when I'm not using a that connection.
Typically, I switch back and forth between wireless and wide connections depending on my location, so I don't want to just simply disable the network device.
I have a wireless network using an Apple AirPort Extreme. That device is set up in my office and hooked up to the cable modem. I have a TV in another room which can accept a wired internet connection (not wireless enabled).
Can I use an Apple AirPort Express's ethernet jack to create a wireless-to-wired bridge? If not, what device would I use to do the same thing?
Couldn't find any help @ google or here.
The scenario:
Windows Server 2008 Std x64 on i7-975, 12 GB RAM. The server is running in a data centre.
One hardware NIC - RealTek PCIe GBE - one MAC Address.
The data centre provides us 4 static external IP's. The first is assigned to the host by default of course.
I have ordered all 4 IP's, the data centre can assign the available IP's to the physical MAC address of the given NIC only. This means one NIC, one MAC Address, 4 IP's. Everything works fine so far.
Now, what I would like to have:
Installed VirtualBox with 1-3 guests running, each gets it's own external IP assigned.
Each of it should be an standalone Win Server 2008.
It looks like the easiest way would be to put the guests into an virtual subnet and routing all data coming to the 2nd till 4th external IP through to this guests using there subnet IP's.
I have been through the VirtualBox User Manuel regarding networking.
What's not working:
I can't use bridged networking without anything else, because the IP's are assigned to the one MAC address only.
I can't use NAT networking because it does not allow access from outside or the host to the guest. I do not wanna use port forwarding.
Host-only networking itself would not allow internet access, by sharing the default internet connection of the host, internet is granted from the guest to the outside but not from outside or the host to the guest.
InternalNetworking is not really an option here.
What I have tried is to create an additional MS Loopback adapter for a routed subnet, where the Vbox guests are in, now the idea was to NAT the internet connection to the loopback 'subnet'. But I can't ping the gateway from the guests.
By using route command in the command shell or RRAS (static route, NAT) I didn't get there as well.
Solutions like the following do work for the one way, but not for the way back:
For your situation, it might be best
to use the Host-Only adapter for ICS.
Go to the preferences of VB itself and
select network. There you can change
the configuration for the interface.
Set the IP address to 192.168.0.1,
netmask 255.255.255.0. Disable the
DHCP server if it isn't already and
that's it. Now the Guest should get an
IP from Windows itself and be able to
get onto the internet, while you can
also access the Host.
Slowly I'm pretty stucked with this topic.
There is a possibility I've just overlooked something or just didn't getting it by trying, especially using RRAS, but it's kinda hard to find useful howto's or something in the web.
Thanks in advance!

I have still have dial-up(cant afford highspeed) and I am trying to configure my desktop with vista to share that connection with Ubuntu Ive got it all setup but ubuntu wont get on the internet at all. Can yall help me with this problem.
I have a CentOS 5.5 server hosted in a remote data center. I usually access this server from a Red Hat Enterprise Linux 5 server using the ssh command. Now my organization has implemented a proxy server, this is not allowing me to connect to the VPS server.
I see the following error using the command root@<ip address>:-:
ssh: connect to host <ip address> PORT 22: connection refused.
Can anybody help me with this issue?
It is possible to use the include = /somepath/%u.smb.conf in the global section to call a script /somepath/cb0.smb.conf if the user cb0 connects to the samba server.
Unfortunately this does not wotk for me because testparm alway gives me
Can't find include file /somepath/.smb.conf
When I connect to the server I can enter a username and pass but it alway rejects the connection.
I'm using Samba Version 3.2.5
How can I achieve to load a custom user script depending on the user that is connecting ?
I'm trying to setup multiple virtual interfaces with VLAN's on a single NIC. I'm running Debian Squeeze.
Currently this is my /etc/netowrk/interfaces
auto eth0.10
iface eth0.10 inet dhcp
This gives me a working connection, however I'm not sure how to configure several like these on a single NIC so I can use multiple external IP's.
I have tried aliasing the VLAN's like so:
iface eth0.10:1
But that was not successful and it said failed to bring up interface.
And suggestions would be greatly appreciated :)
I am writing an application that contains a web server running on port 50000. On Windows 7, short of turning the firewall off completely, I am having trouble configuring the firewall to allow other computers on the same private LAN to connect to the server. Simply adding the program to the allowed programs list doesn't seem to work. The network connection is set to be a "Home" network (but I am not using Home Networking). Can anyone suggest where I should be looking to troubleshoot this?

I see a lot of connection attempts to 1283/tcp on my firewall from a client computer to a Windows Server 2008 Domain Controller. What exactly is this traffic? Something to do with NetBIOS, perhaps?
We have a local network (A) of about 50 computers connected via gigabit ethernet. We get a connection to the internet using two broadband connections to a backbone and distribute the bandwidth across the 50 computers using a CISCO 1811 router, but the bandwidth is not enough for everybody.
There is a campus wide wireless network(B) that has very high bandwidth, is there a device or way to setup multiple individual connections to network B and supply the bandwidth to our network A?
I connect to a remote computer using mstsc on a slow connection. Now I have set the settings in the experience tab to the lowest. I was wondering if reducing the color depth will improve my experience any further
This started happening when I installed Windows 7. I've tried with Filezilla and with the FireFTP Firefox plugin, and I could never connect. Filezilla gave the error message "ECONNREFUSED - Connection refused by server". I tried disabling the Windows Firewall, but no luck. Any ideas on what might be causing this?
I just discovered that I can connect with web services like net2ftp, but not with FTP clients.
I am trying to push DNS to the client with OpenVPN server with config:
push "dhcp-option DNS 192.168.x.x"
It is working well, but what I really need is that during the VPN connection I do not want to use my primary resolvers, clients should use only the DNS provided by the server.
It can be done with push redirect-gateway, but I do not want to tunnel all connections from the client thru the VPN, only specific networks.
Is it possible to do it somehow?
Linux clients are OK with a script, on Windows I am not sure
