Ubuntu Networking :: WPA Authentication Fails After Waking From Sleep Vs. DLink?
Jan 14, 2011
At home in Guangzhou, I have no problem connecting to a WPA-secured wireless router.Now I'm on vacation in another city trying to use a dLink DI-624 router. If I connect immediately after reboot, no problem. If I suspend the session and then wake the machine up again, it will try to connect and then tell me WPA authentication failed.This happens both with network manager and wicd.sysinfo says the network controller is an Atheros AR9285 (ethernet is Realtek RTL8101E/8102E, probably not relevant).Since everything works correctly with routers other than the dLink, I'd have to guess it's not a general wireless configuration problem, nor a wireless card malfunction. Maybe some bad handshaking that manifests only after waking from sleep?More out of curiosity -- I'll only be here for a few weeks and a wired connection is readily available. But, say I end up in a hotel somewhere that uses dLink for WiFi

Since installing 10.04 yesterday my laptop will not wake correctly from sleep mode. Opening the lid wakes the machine up but the graphics are all wrong. Loads of tightly packed horizontal lines. Turning the machine off and restarting makes all ok. It's only on wake up does the problem happen. The laptop is an Acer 1652,with an ATI Mobile Radeon X300 graphics card. Intel Pentium M.

I have a WD MyPassport 320GB external hdd and Ubuntu 10.10. The problem is that I can't access my drive after waking from sleep. I can't even unmount it; gives me an error like: "umount: /media/0A26FE8626FE71D5 mount disagrees with the fstab".

I have had a issue with the trackpad not working (cursor does not move, does not click) after I wake up my MacBook Pro 4,1 from sleep. I am pretty sure this is an X issue and not a driver issue because if I log out the trackpad works again. This is also sporadic. Sometimes it occurs, sometimes it does not. Is there some configuration I need to set to fix this?

I'm trying to connect to my Xubuntu box (zelda) remotely using my RSA key. I'm using Cygwin on my Windows box (link) to SSH in to the Xubuntu box. I've created the key and placed it in the authorized_keys file on my remote box. Here's where it gets weird. When I ssh into zelda the first time, it prompts me for my password. However, if I'm already connected to zelda and try to open another connection, it prompts me for my RSA passphrase. This is very confusing, and I have no idea what's going on.Here's my sshd_config file on zelda.
Code:
# Package generated configuration file
# See the sshd(8) manpage for details

I have been trying to get 9.10 to work with my D Link DWA 125 USB WiFi antenna for days now. I have searched these forums as well as other forums for answers. I have tried all of the suggestions I have come across, some simple, some complex. Nothing works. I have tried ndiswrapper, blacklisting drivers, re-installing, modifying the 2870sta.dat file......nothing works (or maybe I'm doing it wrong...I don't know).
I have a fresh install of 9.10 .Can someone please walk me through this and show me what I'm doing wrong?

I have an Intel DG35EC motherboard with on-board NIC. It is an Intel 82566 Gigabit NIC. It is wired, not wireless. I am using an Ubuntu "Live CD". Just out of curiosity (to see if it worked), I "suspended" Ubuntu and it suspended very well, but when I "resumed" Ubuntu the NIC would not connect back to the network. If I actually installed Ubuntu and didn't use a "Live CD" do you think it would behave differently?

Older laptop I just upgraded to FC13. I would like to use a Dlink DWL-650 pcmcia card. The system sees it.
#iwlist wlan0 scanning
Cell 01, mac, chan, freq and everything else for my base router
Cell 02, same thing for my extender unit
ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:0D:88:AA:AA:AC
inet6 addr: fe80::20d:88ff:feaa:aaac/64 Scope:Link
[Code]...
ifcfg-wlan0 is set for DHCP. Notice above no IP. If ifcfg is given an IP/mask still no IP. So it seems to be up and running, just not accessible.

I've just installed Ubuntu 9.10 in my laptop. Everything works fine except for my wireless. It works, but much, very much slower the through RJ45, which is perfectly ok. When using wireless i can't even connect to any online messaging service and I need to reload pages oftenly. My security setting is WEP 128 bits ASCII and since I'm trying to follow the format suggested on the thread "HOWTO post a Wireless issue" I'll try to provide the infos like requested on it. Laptop brand and model (I'm from Brasil, so it's a brasilian model)

Semp Toshiba IS 1412

ID 0bda:8189 Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter

Does anyone have experience with the D-LINK DIR-655 gateway OR router OR wireless access point? On the surface, I like this box, but it is giving me grief. First, it wants me to use a win-dose CD configurator application. I use the embedded web page configurator. Next, there are several configuration wizards at the embedded web page. After trying the wizards, I went to the manual screens to tinker to get something working.
So what is going on? When a LAN client connects, I want DHCP to present at least two "nameserver" values ... which then make their way into /etc/resolv.conf The DIR-655 plays some nameserver games like caching and blacklisting and other things. However, I get some ad-vert page from "dnssearch" or "yahoo" or similar when names don't resolve. I really don't want this behavior. Network-manager does not report the connection down, however streaming anything stops or "reconnects", browsing times out, LAN side traffic seems to stop as well.

My first post here. I've been using Ubuntu to run our internal mail server for a while now on Ubuntu server 9.04 and ISPconfig 2. I've read a lot of threads on poeple that have difficulty connecting to their server using SSH from outside the LAN and it is not the same problem I have. Well, not entirely the same.
My problem is that my authentication fails from outside the LAn, but I can connect to the SSH port from outside my LAN. The other threads pointed towards checking the router port forwarding etc, but I can see my SSH log in asking for my username and password. So, at this stage I know the port forwarding worked, otherwise I wouldn't even see the log in prompt.
Has anyone see this before where you can connect, but the authentication fails? I can use the correct username and password from inside the LAN, but using the same credentials from outside fails.

One I cant figure out is a problem of authentication. I'm using open ldap server and try to authenticate a groupware (simple groupware) against it. As it fails, I tested with a ldap client to understand things better. Using GQ ldap client, I 'm able to browse my ldap tree successfully and to search some args from the base DN i specified. but when entering the exact uid as a search string iI got no answer whereas searching the cn returns the correct entry (and display its related entry including the uid I can't find ..) Here is the only thing I can trace in logs (syslog) when trying to seach firstname.lastname (= uid)

I recently tried installing a new version of VirtualBox PUEL version, after uninstalling an earlier version. But the major issue I have now is that I can no longer modify my User Settings. Clicking on the "Autnenticate" icon gets me a failure notice: "System policy prevents modifying the system configuration", with details reading "Action: org.freedesktop.systemtoolsbackends.set". Hovering over this link says to click on the link to edit the file, but nothing happens. Searching the file system tells me this file does not exist. Prior to this episode with VirtualBox, I had no trouble modifying Users and Groups. I was able to remove a group from the command line, but the cannot get the GUI authorization to work. I have searched the forums and bugs for similar problems, and, although there appear to be a number of similar issues, no where can I find any clear information on how this system is supposed to work, or what I need to do to correct the problem.

The first time PackageKit Update Applet ran, it asked me for the root passwordI accidentally pressed enter after making a typo, and ever since then Update Appletfails rror:Authorization failedYou have failed to provide correct authentication.Please check any passwords or account settings.Failed to obtain authentication. It never lets me input a new password. Two questions:1) Am I doing something wrong, or is this actually a bug? The possibility has been mentioned in other posts on the topic.2) Where does PackageKit store its files? I'll either change the password myself or delete the file where it's written, hopefully that will trigger PackageKit to ask again.

I just upgraded my Ubuntu 8.04 server to 10.04 and now I cannot receive mail on my Ubuntu 10.04 Evolution client, although I can send mail. No errors appear in auth.log or mail.log when I attempt to log in from my Evolution client, in fact mail.log shows 'pop3d-ssl: connection' from my laptop IP, followed by 'pop3d: Disconnected' when the log-in attempts fail.
I'm able to ssh into the server using the same log-on and password as before the upgrade, however I haven't changed the public or private keys in my .ssh directory. I updated the ssl keys in /etc/postfix/ssl but wasn't able to receive mail before or after the update.
The error in the client reads: 'Unable to connect to POP server mail.mydomain.com, error sending username'
I ran this test and the output appears to be related:
Is the pop3 server not running TLS? /etc/postfix/main.cf says it should, and I get no errors restarting / reloading postfix.
I am receiving messages in /home/user/Maildir, but I cannot download them.
I checked for supported authentication types in my Evolution client - 'Password' is the only one supported, as was true before. The client is not using any certificates.
The output of openssl s_client -tls1 -connect 127.0.0.1:995 shows 'certificate has expired' on the 'Verify return code' entry, not sure if that's significant.
What's different about incoming versus outgoing mail authentication?

I recently upgraded my video card from a GeForce4 MX 440 AGP 8X to a GeForce FX 5500 AGP 8X. After that my 1360x768 monitor was stuck on a 1024x768 resolution. I ran system-config-display and under Hardware tab I changed the monitor setting from "Generic LCD Screen" to "1360x768 LCD Screen" with the acknowledgment that /etc/X11/xorg.conf file was been modified. After reboot the boot process stuck on:tarting kojid: Kerberos authentication failed. "Resource temporary unavailable" (11) [FAILED]I tried that with both 2.6.34.6-54 and 2.6.34.6-47 kernels available on my system.I use the latest KDE version available for Fedora.

I installed freenx-0.7.3-i486-1alien.tgz on the server (with Slack 12.1), all according to instructions. I installed the no machine nxclient 3.4.0-7 on the client (with Slack 12.2). I ran setup and configured. I used the default no-machine keys, not custom ones. Since authentication failed at the beginning, I enabled DBauthentication, and added my user and password, which seemed to allow authentication to occur.
Here is my node.conf:
# node.conf
#
# This file is provided by FreeNX. It should be placed either into
# /etc/nxserver/node.conf (FreeNX style) or /usr/NX/etc/node.conf
# (NoMachine NX style).....

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

After seeing those 4G phone commercials with that newfangled mobile hotspot tech, I have to admit I was eager to trade in my crappy 2 year old CDMA phone for one. That is, until I saw the price tag. 30$ a month for hotspot? No way, so what I did was activate the tethering feature buried deep within the primitive OS accessible only with a plethora of codes and hackery. So long story short: I can now network on the go because Ubuntu sees my device as a "mobile broadband device". Unfortunately, my ipod lacks a USB port for tethering so I use my freed up wireless card to make an AD-HOC network for my ipod to connect through my makeshift modem. Now, my issue is that the modem isn't really that mobile any more because I have to have my laptop OPEN to keep my networks on ,otherwise I close my laptop and no more Adhoc or mobile broadband! So, my question is if I can close my laptop but still keep it connected to the mobile broadband and broadcasting the adhoc network.
