Ubuntu :: Configure SSH Server To Let Anyone From Outside LAN Connect
Jan 3, 2011
I tried yesterday with my friend to create ssh server in ubuntu server via vmware on his pc and we're done it, but after typed this (sudo apt-get install openssh-server ) we don't knows what we supposed to do after that, i google it many times but i couldn't find any what i need, all those guides talks about how to connect on ssh in LAN or by useing 192.168.xx.xx but i need to make connect from outside his network, is that mean he need something like domain name or DynDNS ?, my friend got daynamic ip from his isp and i've seen before many websites offers secure shell able to made it connect.

[code]....
I get 5.0.0 errors re:
Code:
May 6 16:06:32 SERVER1 postfix/error[20357]: 2392F21438: to=<SOME_ADDRESS@hotmail.com>, relay=none, delay=0.17, delays=0.1/0.01/0/0.06, dsn=5.0.0, status=bounced (smtp.live.com)
Here's my main.cf

alias_maps = hash:/etc/aliases
append_dot_mydomain = no
[code]...
I get basically the same error no matter what smtpserver/username/password combination I use leading me to believe its my setup and not my username/password

I 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).

I 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?

I'd like to know how to configure Fedora 14 so my VPN connects and reconnects itself automatically, since the "connect automatically" thing I checked in the network manager doesn't work.Is there a way to make sure that everything uses the VPN, so when for some reason the VPN is disconnected the applications will wait for the VPN to reconnect itself instead of switching to the regular network ?Also since it's pptp VPN I tried to disable Ipv6 but I don't know how to check if I successfully did it, can you guys give me the command line to check that ?

I have a dell wireless wlan 1397 mini card with an ethernet 802.3. Now I am trying to connect by a wired connection. Supposedly a have a bcm5784m nic. I have tried to configue the bcm5784m which was shown it to be regonized through fedora 11, i could activate it, and connection still failed. In my driver list on my dell inspiron and studio 1737 the bcm5784m was not checked as a download i needed. What in the hell am I doing wrong. I have searched exhaustively and have found nothing concerning the wire ethernet card or bcm. Supposidly ubuntu does support the dell studio 1737 laptopForgive my spelling. Oh and by the way I am using kubuntu 9.04 jaunty.

how to configure rdesktop to connect to a Windows (XP/2003) computer, but going through a Terminal Services Gateway or connecting to a Terminal Services Server through TLS/SSL? The command line options or any on-line documentation I was able to find, omits this entirely. Using the Windows Remote Desktop Client (RDP6) you can configure Terminal Services Gateway connections from the Advanced Tab. I suspect that rdesktop, gnome-rdp, tsclient et el can't do this yet as they support up to RDP5. Currently I am using a WinXP VM to accomplish this, but would like to do this natively on my Linux box.

As i describe the thread,i won't be able to configure my NIC to connect to internet which is basically done by just running system-config-network in shell to configure xDSL connection.But instead of system-config-network it contains system-config-network-tui which is used for ISDN connection.And after running system-config-network as well as system-config-network-tui it shows the same output which is in attach file
After some google search it shows that there is bug with system-config-network and it is fixed in system-config-network-1.6.0.el6.2-1.el6 but i wont be able to find it.
As i m not subscribed to RHN

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
