• Has anyone had luck running 802.1x over ethernet using the stock Windows or other free supplicant?

  - by maxxpower

  I just wanted to see if anyone else has had luck implementing 802.1x over ethernet. So here's my basic setup. Switch sends out 3 eapol messages spaced out 5 seconds apart. if there's no response the machine gets put on a guest vlan with restricted access. If the machine is properly configured it will authenticate and be placed into a secure vlan. About 10% of my windows xp users are getting self assigned 169 addresses. I've used the Odyssey Access Client and it worked without a hitch. I'm using the setting to automatically use the users windows login to authenticate, but it's workign on 90% of the machines so I don't think that's the issue. Checking the logs on the dc it seems that the machines are trying to authenticate with computer credentials even though they are configured not to. I'm running Juniper switches with IAS for radius. I have radius configured for PEAP and MSvhapv2. Macs and linux boxes seem to have no issues authenticating. One last thing to add If I unplugging the ethernet cable and plug it back in usually resolves the issue, but I'd hardly call that acceptable for production. Kinda long winded and specific for a discussion, but just want to see if anyone else has had similar issues or experiences, or if anyone knows of a free XP supplicant that actually works with 802.1x over ethernet.

  I received a request to add around 100 users to a linux box the users are already in ldap so I can't just use newusers and point it at a text file. Another admin is taking care of the ldap piece so all I have to do is create all the home directories and chown them to the correct user once he adds the users to the box. creating the directories isn't a problem, but I'd like a more elegant script for chowning them to the correct user. what I have currently basically looks like chown -R testuser1 testgroup1 /home/tetsuser1; chown -R testuser2 testgroup2 /home/testgroup2; chown -R testsuser3 testgroup1 /home/testuser3 bascially I took the request that the user name and group name popped it into excel added a column of "chown -R" to the front, then added a column of "/", copied and pasted the username column after it and then added a column of ";" and dragged it down to the second to last row. Popped it into notepad ran some quick find and replaces and in less than a minute I have a completed request and a sad empty feeling. I know this was a really ghetto method and I'm trying to get away from using excel to avoid learning new scripting techniques so here's my real question. tl;dr I made 100 home directories and chowned them to the correct users, but it was ugly. Actual question below. You have a file named idlist that looks like this (only with say 1000 users and real usernames and groups) testuser1 testgroup1 testuser2 testgroup2 testuser3 testgroup1 write a script that creates home directories for all the users and chowns the created directories to the correct user and group. To make the directories I used the following(feel free to flame/correct me on this as well. ) var= 'cut -f1 -d" " idlist' (I used backticks not apostrophes around the cut command) mkdir $var
