General :: Windows - Establishing A VNC Connection Through A Firewall?

Jun 28, 2010

What's the best way to establish a VNC connection to a computer located behind a firewall/router, to which you don't have access? I have a home Linux computer on a Comcast connection, which explicitly blocks incoming requests, so I can't hit the IP directly, but I'd like to remote into it from an arbitrary Internet connection. How would I work around this?

I've witnessed some commercial products, such as one employed by Dell tech support, which appears to use a public web server, which you visit from the target computer in order to "expose" it to an incoming VNC connection. Is there anything similar that's free/cheap for personal use?

Ubuntu Networking :: Establishing A VPN Connection - Kubuntu 10.10 - 64 Bit

Apr 15, 2011

I have a problem with establishing a VPN connection, it's driving me nuts already. No matter what I try, which packages I (re)install, or how many configuration settings i change.. the result is always the same (see syslog at the end of this post). On the same machine, but on a different harddrive, I have installed Windows 7. The VPN connection works without any problems on this system.

I played already with KNetworkManager, NetworkManagerm, KVpn and so on. Further I re-installed each VPN- and network packages multiple times (eg KNetworkManager, NetworkManager, network-manager-pptp, pptp-linux). Further I tested almost every possible VPN configuration (PAP,CHAP,MSCHAP(v2),EAP,MPPE, stateful encryption, no password, BSD compression)... My syslog is as follow:

Apr 13 18:15:02 defcon-inc pppd[3721]: LCP: timeout sending Config-Requests
Apr 13 18:15:02 defcon-inc pppd[3721]: Connection terminated.

Ubuntu Networking :: Updates Lead To Failure In Establishing A Wired Connection

May 21, 2010

One of the (many many) problems that I had with Ubuntu 10.4 was that I wasn't able to connect using a wired. It really came to me as a huge surprise, because that's a problem that I have never encountered. I had dealings with wireless-issues in the past. But never a wired connection failed. The thing is that we (in the dormitory where I live) had a network problem recently. A hardware piece got fried and we weren't able to replace it for about 3 weeks (go figure :X ). But in the past 3 days or so we're back online. The thing is - none of my neighbours (all of them are using Windows) has network issues now. Usually it was on the contrary - I was the one who had beautiful connection while they had to deal with a load of d@ng. That said - I made a fresh install of Ubuntu 9.10. The problem got resolved and I was as happy as a chick during her first wedding night with Don Goivanni in her bed. BUT after I updated (note - update and NOT upgrade) my system, I was suddenly unable to use the wired connection. The strange thing is that the NM says that I am connected AND I even get some short bursts of network traffic (last for 2-3 seconds) but usually not enough to load even a simple web page. Ping always returns 100% loss no matter how long the package burst lasts. I have slept this night for about 3 hours looking for a solution. None has been found so far. I don't have WAPs at home so wired connection is the only way for me to use this modern thing called internet.

Ubuntu Security :: Establishing A SOCKS Proxy Connection At An Internet Cafe

Aug 7, 2011

I've got my netbook set up so that I can run a SOCKS proxy via my desktop machine. This works fine at home, but I'm wondering what happens at an internet cafe with public wifi.

Specifically, the connection needs initially to be set up with an ordinary direct internet connection so that I can log in to the cafe's router. I'm concerned that when I then set the network proxy to SOCKS host, the router will cease to recognise me and will disconnect me. This particular detail doesn't seem to have been covered in any instructions that I've seen (maybe I haven't looked hard enough).

Fedora Networking :: Establishing A Vpn Connection Using Vpnc / Error Failed To Bind To Address Already In Use?

Nov 24, 2010

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).

As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message


Failed to bind to Address already in use
[user@computer ...]# vpnc-helper --local--port 0

If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.

If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.

Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.

Does anybody have an idea how to enforce that the vpn connection is actually used?

General :: Installing Firewall / Gateway Into Linksys Router To Protect Windows?

Apr 1, 2010

story is my brother is a dindows lover (gamer) and hes been gettin attacked by virus's,etc cause he runs his Vista setup with no firewall or antivirus

He says the firewall,etc slows down the PC too much for gaming He doesnt want to use Linux as his games wont play on Linux as on dindows

He wants to know if you can install a Linux firewall/gateway or whatever into his Linksys WRT54GC router and thus protect his PC without using a firewall or av in it.

EDIT: precisely; he has a Linksys wireless-G connected to a always-on Verizon Westel 6100G modem so its a wired connection, not wireless

Networking :: No Internet Connection When Firewall (UFW) Enabled

Jul 6, 2010

When I enable my ufw it completely shuts me out and I have no internet connection. When I do:

sudo ufw status numbered
I get:
Status: active

To Action From

[ 2] 80 ALLOW OUT Anywhere (out)

But I need to disable my ufw in order to reconnect back to the internet. Why is that? Doesn't the above rules indicate that I should have inbound and outbound traffic even if my firewall is up?

General :: 12 And Windows 7 - Get Wireless Connection To Work On The Network?

Apr 3, 2010

how to get my wireless connection to work on the network. I don't see anywhere to go to see if the wireless adapter is even setup in Fedora. My other question is when I boot up and get the options to select the OS the first one is Fedora but the other one says it is other.

I think that is is booting up the recovery partion of Windows. I don't know how to change it so that it is looking at the correct portition. I know it has something to do with the menu.lst file but when I try to open it says that I do not have premission. I am not sure where to go to edit it.

Debian :: Why Not Establishing Official User Based Repository

Aug 19, 2011

One may argue that Debian is going mainstream being officially supported by Linux Mint. The chances are high that many users may change from the Ubuntu to the Debian base. By now especially Ubuntu's PPA has grown to a huge respository offering almost anything an user would need. But how does that look like in a Debian world?

There are several approaches to establish a "Debian PPA", amongst them debppa, but there activity is low not to say that they are almost inactive and orphaned. As coming from an Archlinux and Ubuntu perspective I do not know the Debian perspectives enough to reason this but am still curious to know about your motives not establishing a userbased repository.

Fedora :: Re-establishing Soft RAID5 From Previous Install?

I had FC 14 installed on an SSD, and 4 500Gig drives in a software RAID-5 configuration. However, just recently, my FC14 failed horribly. Fortunately my admin had recently backed up the /etc directory. When FC14 failed, he reinstalled FC14 on the SSD. Is there any way for me to re-establish the RAID-5 drives, since they were not affected?

General :: Keyboard Shortcuts To Manage Windows/workspace On KDE And RDP Connection

Jul 29, 2010

On PC-BSD 8.1 (KDE) I have four workspaces. I want to launch rdesktop 1.6 in one of them, full screen if possible (I'll settle for nearly-full in a window if I have to), and be able to do the following:

Switch between windows in the remote session using Alt+Tab. Switch between local workspaces using either the default Ctrl+F1 or what I've switched it to, my preferred Alt+F1.

It seems if I use the -K option, I get 2 but not 1. If I don't, I get 1 but not 2. Is there no way to do this? How can I tell rdesktop to send or not send a specific key combination?

Networking :: Setup Firewall / Sys1 Is Not Connected To Firewall For Testing Purpose?

May 18, 2010

I am learning to setup firewall in my home for that i have selected four system(sys1,sys2....sys4) for testing .I have configured sys2 to act as a firewall with two NIC. sys3 and sys4 are inside the firewall . sys1 is not connected to firewall for testing purpose.

the IP assignments are follows :

sys1 : ( fedora, not connected to firewall i am thinking, But i am not sure )

IP : ,
gateway : blank
dns1 : blank
dns2 : blank

sys2 firewall ,IPTABLES )

what happened is that sys1(not connected to firewall) can ssh to sys4(connected,inside firewall),since the rules are written not to ssh form sys1 to sys4..

then I came to know whatever the request I give, It directly goes as sys1 --> sys4. Not as sys1-----> sys2(firewall)---> sys4 .and the firewall is not filtering and processing anything for both inbound and outbound (i think it's my mistake some where). the requests are directly going inside without firewall.
