Ubuntu Networking :: Change The Proxy Settings And Put In The IP Address And Enter The Port To 3000?
Nov 8, 2010
My college providers shifted to a different setting.. I'm not sure what needs to be done. On windows, under the connections tab you need to change the proxy settings and put in the IP address and enter the port to 3000. Questions:
1. where lies the linux (ubuntu 10.04) variant to execute the operation.
2. What can be the major obligations of such a change?
I am sure its siimple enough, but I can't get my net to work properly. The connection provided to the internet is through wireless routers.
I need to enter credentials for a system wide proxy, on a fresh install of Kubuntu 10.04. Everything hunky dory, but: Network Settings->Proxy->Authorization has 'username:' and 'password' grayed out all the time; even at 'Manually specify ...'. The only 'alternative' (not to chose from) is 'Prompt as needed'. But I don't get any prompt, and so I'm out of luck. To me, this looks like a bug. Because one should be able to enter a username and a password there, for good.
Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.
I'm using a Debian servers, as router/firwall.. I've two ethernet interfaces into the server, one for wan and one for lan. The i use SNAT so my LAN clients can access the internet throgh the debian router. That is working... Now i want to be able to access servers on the LAN site from the WAN site, and i wanna use port address translation (PAT). I have a FTP server running on a lan server, so i'm trying to portward port 21.
When people try to access my FTP from the WAN site, they are redirected to the local FTP server, and they are promted for crendentials, but when the credentials are typed, and the local ftp server should answer the wan request, the connections dies.
The wan clients are being promted for credentials, so they are redirected to the local lan server, but after that the connections dies, so i think there is some kind of nat problem, when the local lan server is trying to respond to the wan request..
I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 225.0.0.1/23451 and 225.0.0.2/23452 Receiving on 225.0.0.1/23452 and 225.0.0.2/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [225.0.0.1/23452] take its datagrams from emitter [225.0.0.2/23452] and vice-versa!
I am using Fedora 10 and I need to change the defaults that get set on the serial port.I know how to do what I need to in Windows, but I can't seem to figure it out in Linux.
Windows Settings: Bits/Second '115200' Data Bits '8' Parity 'None' Stop Bits '1' Flow Control 'None' Receive Buffer 14 (HIGH) Transmit Buffer 16 (HIGH)
I just can't set any proxy settings in Gnome 3 Network settings. Is it a bug or...? I installed Ubuntu 11.04 and then used a PPA to install Gnome 3. Some other "problem" is I can't set single click opening of folders...
I need to create two Access Control Lists for my networks using SQUID proxy. The ip address range from 165.165.42.10 to 165.165.42.50 for one network and from 165.165.42.60 to 165.165.42.90 for another network. How can I make it?
I am setting proxy for apt-get application in command line using xporthttp_proxy="http://usrnameasswrd@hostort"But my password contains special characters whi is mandatory in our system. the special characters are not recognised properly and it give authentication failure when i use apt-get..how do i work around this problem?? i know that i could put the hex code for the special characters so the system will recognise it properly, but i dont know how exactly, as i tried it but seems not working.
I recently upgraded to ubuntu 9.10 on my dell d830 ..everything worked great no issues. did my normal mods and packaged updates and the works. this laptop i used at work and home, at work i use a windows 7 vm running ontop of my ubuntu and at home well ubuntu of-coarse. work has a proxy setting and my home network doesnt, so i decided to create two profiles on the system > preferences > network proxy One for home > with direct Internet connect And Another for work for defined proxy settings.
Everything was cool...then the one day when i tried to install graphics card driver, it gave a "cant not resolver proxy " error...i checked my profile and it was on home...i also deleted all profiles and set it to default and it still dont work..firefox works cause you can set proxy setting directly on firefox , but now i cant do any "apt-get" because some how ubuntu is still picking up my work network proxy setting? somehow it like stuck on the work network proxy setting although i delete the profiles too...?
how do i get yum, KPackageManager to use System Proxy Settings for there network access ? by proxy i mean it's a program that uses my phone as the proxy.here is the command adb forward tcp:8080 tcp:8080
now i got it to work for firefox like this localhost 8080 for all protocols.did the same in KDE proxy settings localhost 8080 for all protocols..just need to know hot to configure yum and kPackageManage to use it as well?
I had had my internet connection working using PPPoE, but after I did some tweaking and configuring on the machine (configuring Samba), I wasn't able to connect to the internet and on the syslog said:Code:Cannot determine ethernet address for proxy ARPI'm using dynamic IP address on my internet account. Is this problem related to Samba server configuration that is running?
An application that supports SOCKS 5 protocol can forward its network connection over ssh and dynamically forward to any host name that you specify isn't it ? that means firebox web browser can use SOCKS 5 protocol can be used by pass proxy settings isn't it ? so how can a sys admin remotely detect if a particular user is bypassing proxy settings using SOCKS 5 protocol ?
The problem is that he did not specify exactly where in /etc/profile. I am trying to make a custom spin of F12 but I cannot do it behind the proxy as it is now.
while configuring the yum through proxy i was configures with some address(10.x.x.x). after the proxy address has been changed(172.x.x.x).according to new proxy address i made changes in all locations in my system. but when i am trying to download through command line still it is trying to connect old proxy address(10.x.x.x). finally i come to know that, still some location old proxy address (10.x.x.x).is there.
how to troubleshoot this issue.(how to find the location) i was try to debug find the output below DEBUG output created by Wget 1.11.4 Red Hat modified on linux-gnu.
In order to connect to the internet when i am at work i have to use a proxy server; the problem is that this proxy also blocks port xxxxx which is used by a internet radio station. Is there any way to be able to listen to that radio station?
Here is my network diagram ADSL router----firewall--LAN inside the LAN my squid is running. currently all users are working with out proxy server. I installed the proxy server inside the LAN. now all users can access web browsing ,but no other ports are working , like POP3, smtp, then some other TCP port based applications are not working. My firewall ( juniper) is created and tested the rules to allow the POP3 and smtp and selected poprts which is working , but I redirected through squid proxy server the clients are not able to access. where do I have to create rules?
** in squid proxy( i already did in safe port list stillnot working) ** IP tables?
I'm trying to grok a problem I'm having with an embedded machine. I'm pretty sure I can track down the larger problem, but I came across a usage of ifconfig that I don't understand, and I'm pretty sure this is the command that is failing.
The command is: ifconfig eth0 192.168.78.20:9134
I understand how ifconfig works. What I don't understand is the :9134. I can't see anything in the docs about what this means. I know in most contexts it's a port number, but what does it do when bringing up a network interface? Does it limit it to only using port 9134?
Is it possible to forward a connection to a port to a completely unrelated external address? For example, I want to redirect ssh traffic to a.b.c.d to w.x.y.z. If w.x.y.z were an internal address and the machine was the router, this would just be plain old NAT port forwarding. But what if w.x.y.z is not an internal address? The reason I want to do this is I want to reassign a domain name example.com from ip address A to B, while allowing users to still ssh into A by using the [URL] domain name. Is this unreasonable? (I am guessing it is unreasonable, since the A wouldn't have it's gateway set to B, as is the case if A were in B's NAT'd internal network.)
server: LAMP - debian, apache2, mysql, php5. a bit info on my network: There is a another service here that already uses port 443 already. It made my website time out, hence the move to another port. PLus, i dont want the 2 services sharing the port. What I am trying to do is forward 443 requests to another port where the SSL service is running so I can hide my port number in the URL.
what I have: Belkin G Wireless Router Model F5D7234-4. To attempt to get Subsonic working, I changed the port forwarding settings (Belkin calls it Virtual Servers) to forward port 4040 to my desktop computer. I then saved changes, and my wireless disconnected. I waited about 3 minutes, and nothing was happening, so I restarted my router. This left me in the position that I am in now. Even when the router and modem are fully booted, the router does not broadcast my SSID. In addition, a wired connection will not connect to the network through the router. This leaves me completely unable to use wireless, and unable to change any settings in the router.
I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?
I have recently installed Fedora 13 on my netbook. I wish to use my HP Officejet via the HPLIP utility. The problem with this is that when I have the firewall turned on, the printer is not recognised at all during setup. When the firewall is switched off, the printer is recognised. The printer in question is an HP Officejet 8500a which is connected via Ethernet cable to a wireless router. I would like to know if there are any network ports (that's used by HPLIP) that I could 'turn on' in the firewall that could let my computer recognise the printer.
I want to pass ip address,port address and some parameters from command line using python script.The ip address and port address for establishing socket connection and remaining parameters to execute different connection.
How can I edit the system proxy setting using the terminal? Which file contains this settings? I want to edit this automatically using cronjobs, cause from 8-5 I need to use a proxy, but at home I don't need the proxy. How do I fix this?
Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.
As I try to change my if0 MAC address either from /etc/networking/interface, or from GUI application, when I try to reconnect (through GUI) the application automatically creates some sort of alias interface with the default MAC every time, and leaves the one with the changed MAC aside.
I have a few computers on my home network and I want to get them running at 1000Mbs Both my Ubuntu Machine and my Mac already have the hardware to run at that speed but my switch is 100Mbs so I am going to buy a new 1000Mbs switch. Do I need to change any settings in Ubuntu 9.10 to allow for 1000Mbs networking?
