Is it possible to monitor WiFi connections and identify who are connected through OpenLDAP? If so, how will authentication be possible? By the way, I'm open if OpenLDAP is inappropriate for such authentication purposes and scenario.
View 2 RepliesI was thinking of merging my openldap and samba bdc servers. Is it ok for a server to authenticate against itself? (ie ldap.conf points to localhost)

View 2 Replies View RelatedI have configured a ldap server and trying to login to same ldap server using a ldap user. However, I am not able to login and getting the following in /var/log/secure:

I can see that if I use the ldapsearch with same filter, I am not able to locate the user "ldapu1". However, if I change the filter to (|(objectClass=posixAccount)(uid=ldapu1))", it shows me the ldap user:
[root@redhat5 ~]# ldapsearch -x -b "ou=Users,dc=homeldap,dc=com" -D "cn=Manager,dc=homeldap,dc=com" -W -H "ldap://127.0.0.1/" "(|(objectClass=posixAccount)(uid=ldapu1))"
Enter LDAP Password:
# extended LDIF

# base <ou=Users,dc=homeldap,dc=com> with scope subtree
# filter: (|(objectClass=posixAccount)(uid=ldapu1))
# requesting: ALL

Where I have made a mistake?
- Is it necessary to create an account on Linux box and then migrate it to ldap?
- I was just wondering if I can somehow change the default filter from AND to OR at the time of login. I used "pam_filter |objectClass=inetOrgPerson" in ldap.conf.
However, it didn't change the filter.
Is it possible to set up slapd to authenticate users using a simple name instead of a dn?
View 1 Replies View RelatedA time ago I've been trying to implement a PDC linux server with Samba and Openldap for centralized authentication for windows and linux clients, but I can NOT get it. So I read somewhere that there is another option called Directory Server and maybe that is possible to do. According to your experience do you recommend any 'how to' or 'tutorial' that will permit implement a PDC server for authenticating and sharing files and printers for windows and linux clients?

View 7 Replies View RelatedI am using ubuntu in my new office, and I can't get the network working. The "official" OS installed was a Windows, and it has a special "dial-up" app for the LAN connection (not wireless). My network admin is apparently not helpful, since he actually knows nothing about the internals for the "dial-up" app (he did not even ever heard of TTLS, PEAP, MD5, etc), and claimed that no OS except for Windows can work...
Well, I have tested various configurations with my Mac laptop, and apparently the LAN connection requires 802.1X authentication, and it's using a very weird combination "TTLS+PEAP+MD5" (if I check these options in Mac OS X, the connection works). However, in NetworkManager, I can't select both TTLS and PEAP, and moreover, TTLS does not work with MD5. So, is there anything I could try?
I tried to get my 3G connection up with my Lenovo Ideapad S10-2 and its built-in Ericsson 3G modem. Well, as I found out after some time of debugging, it didn't work because my network provider only accepts PAP authentication, and regardless of the configuration within NetworkManager, the ModemManager always tried CHAP authentication.
I guess this is because the dialog of selecting PAP, CHAP etc. seems only be used for pppd, but not for the internal setup of the 3G modem.
For the Ericsson (and possibly other modems), the authentication for a packet connection is done with the AT*EIAAUW command, which is hard-coded in modem-manager to use the defaults for authentication.
I patched my ModemManager to allow only PAP in the AT*EIAAUW command, and this worked out perfectly. You can find the patch below. Beware that this is certainly not something that should be included by default, only given here for reference.
Frankly, I don't know who to address to talk about a possibility to get this feature (authentication method selection) in the ModemManager in a clean fashion. I'd be happy to provide some assistance to improve the ModemManager. If someone could provide me with a hint who to talk to or what to do next.
For your reference: the "00010" in this case references a bit-field of 5 positions, whereas the bits mark the authentication algorithms (MS-CHAPv2, MS-CHAP, CHAP, PAP, NONE) respectively. So, 00010 enables PAP and disables the rest.

View 2 Replies View RelatedI just recently installed Ubuntu 9.10 on a dell laptop. My WiFi connection that I've been using on the same computer for years is not working when I log on. However if I run the burnt image cd and choose the option "Use Ubuntu without making any changes to your computer" I am asked if I want install proprietary drivers. If I activate one "Broadcom STA" I can connect to the wireless connection in my house. When I am using the version installed on my laptop it doesn't ask me if I want to install the drivers and it doesn't even find them when I go to hardware drivers under system. So to sum it up I can get connection when I run Ubuntu from the cd but not when I run the Ubuntu on my laptop.

I'm brand new to Ubuntu, and Linux in general, and honestly don't know what I am doing. I installed Ubuntu 10.04 on my external hard drive and am able to boot fine (other than an issue with my monitor falling asleep because my graphics card needs a different driver. I have a work around for this that i'm currently using but I would like to fix it permanently and thus need an internet connection.)
When trying to connect to the network in my home, I am unable to. I click on the WiFi symbol in the top right corner, and I can see my network. I then click it and a page comes up asking for the key. I put it in but it doesn't sync and usually after a minute or so it pops back up asking for the key again.What can I do to gain internet access? I'm unable to connect my computer via a hard wire Ethernet cord and need to sort out this WiFi issue.
I bought my MacBook Pro at the beginning of the school year when I went to college. I am now living in a dorm where I do not have access to wired internet connection, so I cannot just plug my computer in to download stuff. If need be I can of course borrow someone else's computer to download something and then just transfer it over with a flash drive.
Anyway, I have a virtually new MacBook Pro that I bought in August. Using refit I have dual-booted OS X and Ubuntu (obviously I am posting this from within OS X) but I cannot manage to get connected wirelessly to the internet. I have tried this many many times with many many distros and have never once been able to connect. I understand that there are various tutorials around but none of them seem to help me at all and I really want this to work. I've been looking around and trying things for about two days now. Can someone give me step by step instructions (or point me toward some simple ones) starting, if need be, from a fresh install as to how to get wifi working on my macbook pro? I am also completely willing to switch versions of Ubuntu if that would help.

I have been using Linux via my Acer Aspire One for a few weeks now without any problem. Suddenly I find I can get a WiFi connection but consistently it fails to load the pages. I have tried 2 connections so I know it's my machine. And probably something I have touched. How to reset the the internet settings or better still can I reset the computer back a few days (like in Windows) to resolve this problem?

I have the wireless detection, but when I attempt to connect to Fios WiFi it continuously asks for my WEP (I have the correct WEP and I have typed it in correctly) and fails to connect.
I've read about the driver and firmware on linuxwireless and kernel.wireless. org.

Why is this happening? How can I fix this?
I cannot authenticate on my wireless network. it keeps asking me the WPA key (which I correctly enter everytime it asks me to). I COULD do that before rebooting. Now I can't. Nice.
What can I do? I've read somewhere that in the RC there where problems with the network applet I don't know what... can this be reconducted to that?
Wifi network operated perfectly with f13. Upgrading f13 to f14 did not show any problems except for networking. It seems that the wlan0-link is not ready. Consequently no network information about adresses can be obtained. Tried with network tools to activate wlan0. No reaction Tried to deactivate Networkmanager and bring network up with
service NetworkManager stop
ifconfig -a
Then
ifconfig wlan0 up
dhclient wlan0
No reaction on network. The NetworkManager icon disappears which is understandable.
Using an old (5 year) laptop with XP loaded I installed wubi to save altering partitions etc. It all downloaded fine and connected to the internet by wire. I set up the wireless connection using WPA but could not connect. The wirelsss card does see my network and others. After lurking around the forum and trying various things I found that I could connect without encryption. The more I read the more I became confused.
Anyway what I could glean about my Wireless Card it is a Intersil Prism2 mini usb adapter - but also shows up as an Acer ?? Warplink 802.11.
Using lshw I found this reference to wireless
I became even more confused and got a bit lost using the various codes in the terminal and looking up things about drivers etc but would like to persist.
I've been having 2 issues with my internet connection on ubuntu for as long as I can remember, I've tried updates but they haven't seemed to work so great and am pretty fed up with this. So I have a Netgear wg111t wireless usb dongle which I got working through ndiswrapper. The 2 issues I am having are:
1. After a random period of time my internet just decides to disconnect, the strange thing is the bars at the top still say I'm connected. The only way to get the internet working again is to turn the pc off and on. Another way I have experienced this happening is usually when I'm downloading something off a torrent.
2. After restarting my pc the wifi usb isn't recognised and I can't connect to the internet.
I'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.
I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.
There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

I have a Dell Inspiron 1525 running Jaunty Jackalope. I have a good working wireless connection.
My daughter has a lot of iPod tunes stored on an old white chiclet Macintosh, which she needs to download to her iPod. Because the iPod is "corrupt" (meaning it was last connected to Windows!), we need to connect to internet.
Simplest way to do that would SEEM to be to plug an Ethernet cord between the two machines and let her Mac access internet via this Dell.
My experience with ethernet is, either it works out of the box, or it doesn't. If it doesn't, I have no idea how to make the connection work.
What do I have to do on BOTH the Jaunty and OSX sides to make the connection?

Here's the situation: I've got an eee pc 901 running Ubuntu 9.10 netbook remix. I'm using it to connect to a WPA-encrypted wireless network on a WRT54GL running dd-wrt. It mostly connects and works ok, but sometimes it just stops working for no apparent reason (the netbook still shows itself as connected), but you can't get anywhere until you manually disconnect and reconnect. Other times, it will drop the connection, and then quickly reconnect (or sometimes not). Obviously, this behavior is pretty irritating. At first I thought the problem was with the router, but I checked the logs there and they all seem fine, and other computers on the same router don't have this problem. Looking at "dmesg | tail" on my netbook, I see a lot of instances of the following error, which I'm thinking is probably the problem:
Code:

I searched for that error message and I found this Ubuntu bug report: [URL] that describes symptoms that match mine. In that report, a poster mentions that he compiled and installed a new version of the wireless driver from the Ralink website, and it fixed his problem. Do you think installing a new driver would be good? Or has that updated driver already been added to the kernel since that bug report was filed? I've never compiled a kernel module before.
One other thing, I also see repeated instances of these lines (or similar ones) in dmesg, which look like they could be related.
