Networking :: Unable To Connect To Services On Box Through WLAN?
Jun 20, 2010
I have a RedHat linux server box connected to LinkSys router through ethernet port. I've assigned a static IP to the Linux box, which is out of range with router's DHCP range.
The Linux box has Apache, JBOSS, SVN and several other services installed, but none of these services are accessible through the WLAN. However, SSH and SFTP are accessible from WLAN.
Another interesting observation is that if I open a browser on the linux box (by exporting the DISPLAY to Exceed on my laptop on the WLAN) and point the browser's address bar to localhost:80 or localhost:9080, then I can access these services!!.. So, I suspect that something is wrong with accessing these services from a client on WLAN and I am looking for a solution for the same.
I am trying to connect to a WEP encrypted WLAN without using the DHCP server of the AP. (=giving myself a static IP)
So far i have tried:
But i cant even ping 192.168.1.1 (Network unreachable error). Is it possible that Ubuntu tries to use eth0 (which was connected to a similar /16 before) to ping 192.168.1.1 or is there somethign wrong with my commands?
Also will an AP allow access to the network although i don't have an IP from its DHCP server?
Since I have installed Fedora 13 it seems that I can't connect to WLAN APs which aren't secured by WPA. I'm surprised about the inserts to the messages logfile:
Most surprising insert for me: Jul 5 20:43:21 nbtobiaslnx NetworkManager: <info> Config: added 'key_mgmt' value 'WPA-PSK' Is this the reason for my problem? I use KDE and Network Manager for managing my networkconnections.
I have a problem on Ubuntu 11.04 64-bit. The wlan does not connect automatically on reboot, although "Connect automatically" is ticked in network manager. I always have to choose "Connect to hidden wlan", choose my config, enter my password, then connect. Once connected everything works fine. But it's kind of annoying to manually connect each time after a restart.
- hidden SSID from router - mode -> infrastructure - connect automatically -> ticked - available to all users -> ticked - Encryption -> WPA & WPA2 personal
recently I risked a look to the Linux world and I'm happy so far, but now I've got a Problem, I'm unable to solve by myself. I installed Mint (Julia) on my old Laptop to test Linux. The Laptop has a very old PCMCIA WLAN Card with a Realtek rtl8180 chipset. Everything seems to run perfectly so far with one exception: the WLAN doesn't find any Network to connect although the card and the driver seem to be installed correctly.
Here some code from the terminal:
Code: lspci 00:00.0 Host bridge: ATI Technologies Inc RS200/RS200M AGP Bridge [IGP 340M] (rev 02) 00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 340M] 00:02.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03) 00:03.0 Modem: ALi Corporation M5457 AC'97 Modem Controller
I upgraded Ubuntu to 11.04 I can NO longer connect wirelessly using my BCM4312 WLAN Card. It connected with no problems before dist upgrade using Ubuntu 10.04. Im really not sure why I cannot connect. I cannot even see my router in edit wireless connections settings. I can however see my neighbours routers who are using WPA2 encryption. But I cannot see my router.
I have uninstalled and reinstalled The Broadcom STA proprietry wireless driver several times using Additional drivers. This did not fix my issue.
I am connected by ethernet at the moment so I do have internet connection.
I have a ThinkPad x100e with a wireless card.Code:03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)my problem is that I can't connect to my wireless network with Gentoo. I've been running Slackware64-13.1 on this computer and now have Windows 7, Ubuntu and Gentoo installed. Slackware, Ubuntu as well as Windows 7 connect to the wlan without problems. I'm using the driver rtl8192se, the module is loaded r8192se_pci and is the same with Slackware and Ubuntu.
I've read many posts and found that other people experience problems with Realtek wlandevices as well. But I have no Idea how to get connected with Gentoo at my wlan. It looks like that the netbook is connected for a very short time, but when dhcpcd broadcasts for a lease the connection is already closed.
yesterday I installed pulseaudio and pavumeter. This morning I couldn't connect to the internet anymore. I checked the settings but couldn't see any changes. I read the post at [URL]?t=370108 and I'm going to post the outcome of the instructions here:
I have Ubuntu 10.04 installed and can browse the internet via cable, but wireless isnt working. My wireless driver is "Broadcom 802.11b/g WLAN".
In the windows device manager, I found the corresponding inf file to be oem20.inf which I tried to install it through "Setup Windows Driver" but it gave an error saying invalid driver. I also tried installing the Broadcom STA driver, but that didnot help.
I am dual booting with Windows 7, and i installed ubuntu through the windows wubi installer. My laptop is HP Pavilion dv4. I have installed the regular Ubuntu desktop and have made all upgrades. The results from lspci command i have added below.
gowda@ubuntu:~$ lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
so far i testet 4 wlan cards (prism, ?zytel?, realtek and another realtek) they all work without a problem with kubuntu. but with ubuntu they dont want to build up a connection to my router. it looks like the passphrase is wrong..he asks me after a short time to reenter the phrase. but the phrase isnt wrong(copy pasted) the phrase has some special characters but only '=' and a few '!'. so i doubt that that could be the problem im pretty sure there are more people out there who have the same problem. I hope someone knows a solution :/
edit: i did some searching and found this... seems to be a major problem[URL]...
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."
I've decided to try out Ubuntu again on my Samsung netbook. I tried 9.10 before and a lot of things didn't work so I gave up, but that was quite a long time ago and I wanted to see if the new one will work.
I booted 10.10 off the USB stick, don't want to zap my Windows 7 installation if Ubuntu doesn't work. Everything seems to run fine, the webcam works, wireless seems to work, it shows the networks in the range and allows me to pick the one I want to connect to.
Sounds good so far, but when I try to connect to my WLAN and put in my password it thinks about it for a while and just pops the password again. It can't seem to connect to the network even though it sees it and the password is correct. I triple checked the password, it's definitely correct.
I can only assume there's something wrong with ubuntu and the driver. I have a Samsung N140 netbook which uses Realtek 8192E chipset.
Linux is what i'd like to learn, so Howdy to all and i hope to speak to you all regularly in short, I started with Ubuntu Linux about 6 months ago, Didn't like it, i researched various distro's and came across, PC Linux OS, it was really cool, But i couldn't get it to connect Wirelessly, so i tried something else... the bottom line is i finally settled on SUSE Linux Enterprise Desktop 11, i seem to like it a lot.Ok.. now that introductions are out of the way
Background info: I've installed SUSE Linux Enterprise Desktop 11 on my Sony Vaio Laptop (VGN-NW15G) with no major issues, after a bit of mucking around, i got the LAN to Connect to the internet, after some more mucking around, i figured out how to get the WLAN to connect to the internet.MY Goal: To be able to Wirelessly Network my Laptop with My PC.so that i can access the files on the PC, From my laptop, and Vice Versa, but the important thing is to first be able to access the PC files from the Laptop.
NOTE: My PC has 4 Hard Drives (1 for the O/s, 3 Backups) they are all configured and Shared correctly for Networking and Wireless networking, and all the permissions are set correctly.Hardware and Software Environments:My Laptop : Sony Vaio VGN-NW15GOperating System : SUSE Linux Enterprise Desktop 11Wireless Capable, and has no issues Wireless Networking when running of a Hard Drive Loaded with Win 7 Ultimate 32bit, Therefore all Hardware is Compatible
My PC (Custom Built) Operating System : Windows 7 Ultimate 64bit SP1 Motherboard: Gigabyte GA-X58-UD3R Rev1.0
Since a recent update on Stretch, I have been unable to use the network-manager to connect to my home wireless network on my laptop. It was working fine before. I did not change any settings on the WLAN router. I can still connect to other wireless networks at work and university, just not this particular one at home. All other non-Debian devices in my household are still able to connect just fine.While figuring this out, I have tried connecting manualy with ifup but I don't really know how that works. Right now there is only the loopback entry in /etc/network/interfaces.
Below is the output of syslog, when gnomes network-manager is trying to connect, but fails. Code: Select allJul 19 20:01:57 debian NetworkManager: <info> (wlan0): Activation: starting connection 'Affenbande' Jul 19 20:01:57 debian NetworkManager: <info> (wlan0): Activation: Stage 1 of 5 (Device Prepare) scheduled...

I've tried out many Debian distros and noticed the ones that I try based on Ubuntu, my USB WiFi adapter works fine and I don't really have any issues. When I try one that is based on current Jessie, I have sporadic WiFi issues and just overall instability with regards to connectivity and audio playback. I have tried two distros based on Jessie and had very similar results on both. Is there anything in particular I can try? I've done everything short of installing Debian stable and just pointing to Jessie. I've done that in a VM so I know I can handle it, but wanted to se if there was anything I should be trying first. I just didn't think a distro based directly on Jessie and Jessie backports would be any different from installing base Jessie as far as compatibility is concerned.
Under OpenSuse 11.2 i cannot connect to my wireless network. Sometimes computer doesn't see network, sometimes computer cannot connect to it. Encryption: WPA & WPA2 Personal Kernel driver: ath5k Also I am embarrassed that in lspci and yast written various models of my wifi adapter.
I have installed opensuse 11.2 on a second partition, with the ultimate aim of leaving windows altogether. Unfortunately, I seem to be having terrible trouble (as do many others) getting my wireless internet connection working. I have viewed lots of posts in these forums and done everything I can think of, but since I am a linux novice, am unable to identify the problem. The card is working, since it can identify local SSIDs, it has been set up (to the best of my knowledge) correctly in YAST, but nothing seems to work. I'll include some information I have recorded from my system.. I typed the commands below with the accompanying output listed:
I'd like to go one step further now, with my laptop. As I'll be travelling more often in the foreseeable future, I'd like to be able to connect to WLAN hot spots in hotels, railway stations and air ports with a minimum of hassle. What's the best way to go about it?
Of course, Wicd is quite useful, but I'd prefer a KDE application, and I'd like to be able to define "profiles" for various scenarios. Certainly I am not the first Slackware user with this requiremnent, and probably there are tons or docs regarding this topic. However, searching LQ and the internet I haven't found what I am looking for.
I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only. I had follow this how-to [URL] and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works. I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, I install VM player on it and run CentOS inside the VM Player.
I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?
Browsing here and there I finally succeeded (well almost) in setting up my home-made router/firewall/filer/nameityougotit server. Everything seems to work (using ethernet or wireless connections) but I still have some questions:
WAN: eth0 LAN: eth1 and wlan0 are bridged (br0) together
Question 1 I am unable to play games using UDP between wlan and eth1 although it works when both stations are connected to eth1
Question 2 I used ufw to help me setup IPTables but I am not really happy with this tools. Since my network configuration must be quite common, point me to a regular IPtable setup script or give me the rules I should add?
I'm facing a problem with 'ssh'. In my lan environment i've configured a system with fc12 and one more system with fc9. When i'm trying to login through ssh from fc9 to fc12 it's working, but at the same time if i'm trying to login through ssh from fc12 to fc9 it's not working. I was getting the error "connection closed by remote host"can any one suggest me how to recover this.
I'm trying to connect via ssh from a remote to a local machine.The local machine is connect to the ISP thru a wireless router. I know the ip address of the local machine from myaddress.com. The local machine is running sshd. I can ssh from the local machine to the remote, but I'm unable to ssh from the remote to the local. I know the local machine has not yet changed its port number.
I have Karmic Koala and together with my neighbours we have a W-LAN which I was always using without problems. Now, a couple of weeks ago, my neighbour has changed the password to this W-LAN and since then ubuntu is unable to connect. The network is being recognized, but after the request to unlock a key for the network manager (besides, how can I unlock it once for all?) there comes the window with the request for the network-password, after typing it (correctly), nothing happens. The request for the password comes two more times and then ubuntu states that it is unable to connect.
- We have changed the password again - didn't help - On Windows I and my neighbours get the connection - My Ubuntu is able to connect to all other W-LANs
