Networking :: Proxy Setting - Doesn't Work With Etho(wired)
Mar 7, 2010
I got a problem about network proxy setting. With the graphics setting interface, I set auto proxy with the URL address but it is weird that the setting only work with eth1(wireless), doesn't work with etho(wired). however my wireless driver is always a problem for Linux. i also tried export http_proxy= XXXXX:8080 it still doesn't work at all.
I've brought a friend over to linux from windows. He has some how deleted his "Wired Etho" connection. He said his computer would not shut down(Mint Linux 9), so he unplugged it. You guessed it right after restarting no internet. After checking under "Network Connection" his wired connection is gone. My question is? How to reconfigure a "Wired Etho" connection? He has a dsl connection running a Linksys router(sorry I don't know the model number). I have only talked with him on the phone, so I have not personally checked the system out. I just finished working on it this past sunday and everything was fine.
I recently tried out OpenDNS on my wired connection, however after it was slower than faster, I tried going back to the original settings that the connection had (so basically to Automatic DHCP).
For some reason the connection wouldn't connect again. So I thought I'd try deleting that connection and creating a new one, but this still doesn't work. When I try to connect using NetworkManager it just does the 'loading' icon for 30ish seconds then says disconnected.
My wireless still works fine however.
I'd very grateful as i'm worried i've messed up the ethernet port and I need it for when I got University in a couple of weeks
what is the command to restart the network services? ive forgotten i think it uses -hup switch though. about 1 in 20 boots on my desktop ubuntu system results in the system insisting its no longer on a network yet has a fully functioning network card. a reboot always fixes the issue but that doesnt seem like a long term solution to me. If I ping a neighbouring system I get nothing. (sent packet count increases in ifconfig) If I ping from a neighbouring system back to my desktop I get nothing (no change in packet count) I can bring down and back up the network interface with no results. A sniffer shows the system definitely isnt sending anything out Everything worked previous boot and will work again after a reboot.
These days I wanted to connect to the internet on my laptop using a wired connection. When I inserted the ethernet cable, I was surprised to see that it doesn't work on Ubuntu 11.04. So I decided to boot into Windows and see if it works or not. And I found that it works without problems on Windows.
My desktop PC has 2 NICs. I have Ubuntu on it since several years, and I remember that both eth0 and eth1 used to work. However, I discovered recently that currently only eth0 works, and eth1 is dead, but I don't know why. It's been a while since I've tried eth1, so I have no idea when exactly it broke. I suspect the problem may be related to the fact that the MAC address is incorrect: it is set to 00:00:00:00:00:00, which seems wrong. But I have no idea how this happened...Any idea what might be wrong and how I can fix it? Here is some output which I think is useful:
Code: peter@cheetah:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr 00:18:f3:68:42:78
I have installed Ubuntu 11.04 using Wubi through Windows 7. It seems to be working but it will not connect to my wired internet connection. It tells me there is no wired connection, when there is. I used sysinfo and its not showing any network adapter or controller. I have a board with nvidia nforce go 430, could it be a driver issue. It works fine in windows though. Tried using a wireless adapter and all is working. But why doesn't the wired ethernet connection work.
I'm having mysterious wired network problem with my Karmic/9.10 machine. It hasn't been in network a while, but now I finally got the cabling done. I can't get the IP from dhcp server (TW-EA510), and static settings doesn't work either. Fresh cabling showed OK 1Gb connection on tester, and win7 laptop works fine. I even tried with long cable though the rooms, but it doesn't help, so it definately isn't the new cabling.

Motherboard is some old Lanparty with two ethernet ports, NVidia CK804 and Marvell 88E800 rev 13 Gigabit netwok adapters, neither of them works. At least another of them has been worked earlier when I last got it wired. It's been a while, so I'm not sure which one of them and with different router if that matters.
I have installed Ubuntu 10.04 LTS on my Compaq 767TU notebook. Everything is working fine except "Realtek RTL8139 PCI adapter". Although it is showing up in device list and installed but the LAN link indicator lights are off. No communication is possible with dhcp.
I run a HTTP/HTTPS proxy server but one of our clients is having trouble accessing [URL]Can anyone see if the login button is using some kind of weird connection feature? I thought it might be using flash or something rerouting the connection through something other than port 80 (or 8080 for the proxy) but not sure if that is the issue.I just used a fake login and password but instead of giving me the incorrect password error the page just hangs.
I am a complete noob with computers, especially when Linux is installed.The problem is that when I plug in my wired network cable - it just dont connect. Writes "disconnected".I do not use a modem, just a single cabel.I think the problem is just in my knowledge which numbers where to wirte and which one to tick.May you please write what I should wirte ( IP, MAC or smyh)and shouldnt write mannualy and where. What to open and even the smalest step.
Setting up an Internet proxy In the past I had set a computer to act as an Internet proxy. This would be multihomed, and running dansguardian, tinyproxy and firehol. Then webmin would be used as interface. By time I realised that this system is far from effective. Is there some other way to setup a proxy to be placed between users and the Internet? I would like (the admin) to be able to see in which sites users go and have a lot of control on access..
I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use
iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that is listening on port 1234. The proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy and if it sent out to port 80 it would just be a infinite loop) so I want to do something like
iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip?
I have 2 workstations that I'm trying to network together so that I can backup each to the other. One is XP sp2 and the other Fedora 9. Since installing Samba on the Fedora box and trying to get it configured, I have a problem that Add/remove programs won't do installs because it says there's no connection to a network. Network Manager says there aren't any connections, but it worked before the Samba install. Mozilla and Thunderbird can access the internet OK. Both workstations are connected by cable to my router and thus to my ISP (DNS server).
Two questions:- where can I find hints on setting up a wired connection (which card's MAC address does it want? router or wrkstn?) and Am I right that Add/remove is stuffed because of Network Manager?I now have Samba working from Linux to XP, but still can't get into Linux from XP. I tried the Linux PC's MAC address and set up a wired connection in Network Manager. NM still thinks there isn't one...
I used windows OS and installed Ubuntu 10.04 (amd64) in separate partition and works well but had a problem in internet connectivity. Likely reason may be the proxy setting that we used in college (currently). I used this commands to set up the IP address and gateway.
ifconfig -a | grep eth "eth0" sudo ifconfig eth0 192.168.5.209 netmask 255.255.255.0
Then I manually set the proxy setting of HTTP which is given as proxy server 192.168.5.2 and port as 8000, further more there is a wins setting which is 192.168.1.178, really don't know where to put this number.
i must make this work with the use of virtual pc's. I have vm player and installed fedora ( the latest version ) and one xp . So i have 2 virtual pc's. I'm making it simple for start so i can add more pc's when i see that it is working. I have setup a dhcp server at the fedora virtual pc. The fedora virtual pc is like a soho router. The xp pc is getting ip from dhcp while the fedora one has a static one.
My pc is behind an adsl router. Both virtual pc's can see each other which means i have no connectivity issues.Im trying to setup a squid proxy ( transparent one ) so for example the xp pc can access porn sites and such. I used all required configuration for the squid to work and started the service. Ive also inserted with iptables the commands to forward all incoming port 80 packets to port 3128 ( the squid ). It doesnt seems to be working and i thik i know why but i dont know how to fix it.
Because the xp has a gateway at 192.168.1.1 ( the adsl router ) packets go directly to it and not to the soho router ( fedora virtual pc as i intend to do) What can i do to solve this problem ? How can i forward all packets to go to the fedora virtual pc first and then the fedora pc to forward them (if necessary) to the adsl router? PS. I used Bridged connection on the networking configutration on the vmware player ! If you also want i can post the code for squid or iptables if needed !
I bought a switch, connected it to our router,and moved the patch cords to the switch. All but one of the workstations connect & work fine. If I plug the non-connecting wire into my laptop it connects. If I plug the non-connecting wire back into the router,the workstation connects.So...it seems that this particular workstation will only see the address of the old router. It's stuck in there & won't refresh. Two of the PC's & the laptop are running 10.04 (Mint 9 Actually), and one has Windows XP on it.e problem is with one of the 3 10.04 boxesI have tried removing the power cord & MB battery and leaving them out over night.Also cleared the bios. Same results. Connects fine to the old router but will not connect to the new switch.
I have some Flex and Java files which can be compiled with JDK1.5. My server was already loaded with 1.4 (at path /usr/bin/java) and our sys admin(I dont know why) copied another JDK, JDK 1.5 at path /usr/java/jdk1.5.0_16/. It seems very easy to use this java. Just set the path in .bash_profile. I did it and now if I run which java I still see the path for java 1.4 not java 1.5. Am I doing something wrong? Following is actual entry from bash_profile
I want to ssh, scp, git fetch, etc. without a password. I saw the previous questions, and closed ones regarding this issue, but the suggestion seems to be to use ssh keys. However, after setting up ssh keys, I am still asked for my password (it's not asking for my private key password; it's asking for my login password). How am I supposed to set this up so that it only uses my private key for authentication?
I recently got a cable modem from Comcast, and connected a Belkin F5D7230-4 wireless router to it, then connected my computer and an Xbox 360 to the router with ethernet cables.
My computer dual-boots Ubuntu 9.10 and Windows 7. In either operating system, the wireless connection is flawless. In Windows, so is the wired connection. But in Ubuntu, there's a lot of trouble with the wired connection -- specifically, while I can connect to the router and to the Internet, and while I can use ping, dig, traceroute, etc., to verify connections to remote hosts, Web browsing, or anything else that uses http, works only for a few Websites, and then only erratically.
I don't believe it is a DNS problem -- testing with ping, dig, etc., demonstrates that, and I have also tried using alternate nameservers. I also don't believe that it is an issue with IPv6, as I've tried the fixes usually suggested, including editing the grub configuration to disable IPv6 support in the kernel and verifying that IPv6 was inactive. I've also tried using local dns servers such as pdns-recursor. None of these things seemed to help.
Also, perhaps unrelated, but disturbing: my computer has locked up a few times while testing the wired connection, and I had to use a hard reset to restart the computer.
Using 10.10 and have a wired connection that according to the system is connected, but when I open a browser I can't connect to any sites. What am I missing here? I can't for the life of me figure this out.
I've got Puppy Linux on a USB key, and yesterday, while I was on the internet with it, it hanged. I didn't know what to do, and I rebooted from the button (I now know what to do ). The problem is that, after rebooting, Puppy doesn't recognise the router. I've tried to apply the drivers that are on Puppy, but there aren't any compatible.
My router is a Xavi 7968 and my Network Card is:
NIC Fast Ethernet PCI Familia RTL 8139 from Realtek
(On Realtek's website, there isn't any driver linux-compatible)
I just started having a problem with my 10.04 laptop a few days ago, maybe Thursday, last week. When the computer is plugged into my home network (standard 192.168.1.1 sort of IPs) it works fine, but when I try to connect to my work network (130.15.90.XX) I am unable to pick up an IP. The router in my office is working fine, all the windows boxes can connect.
I've also noticed that when the computer is plugged in at work the notification icon for the networking indicates it is looking for a wireless connection (rather than the normal up/down arrows), even if wireless is deactivated
I can set a static IP in /etc/network/interfaces and everything works, so it seems to be a DHCP problem?
I'm running Natty and trying to troubleshoot my ethernet problem. An old laptop worked fine (including the ethernet) until a few days ago when we had a lightning strike relatively nearby. It appears power went out briefly or there was a spike (all hardware, except the DSL modem/NIC, had surge protection). The machine works fine now... except the network. I've run lshw -c network and it's showing "network: UNCLAIMED". ifconfig shows only the loopback and no eth0 at all. I've tried: ifup/ifdown, rebooting, live booting Natty off a USB drive, and tried on a network I know works... all to no avail. One interesting bit of info is that I can see a MAC address when I view the 'network connections' via the applet in top panel.
Am I reasonable to conclude the ethernet port got fried by the lightning? Any pearl of wisdom is welcome.
when i'm connected with wired (eth0) to my access point vpn connection connect flawless but when connect with wireless (eth2) to the same access point vpn connection failed i don't know whats the deal. i try disable eth0 (ifconfig eth0 down). it's disabled now but vpn connection still didn't work
