Re: [CentOS] SSH login from user with empty password

This error is when you ssh in (with PuTTY, for example) without attaching the private key. -------- Original Message -------- Subject: [CentOS] SSH login from user with empty password From: Michael Schultz <m.schultz(a)srz.de> Date: Thu, October 10, 2013 3:44 pm To: centos(a)centos.org Hello list, on a CentOS 6.4 machine I'm creating accounts with empty passwords. Each user's public key is located in <user's home>/.ssh/authorized_keys. When trying to ssh into that machine, following error message is displayed: Permission denied (publickey). In /etc/ssh/sshd_config I've set: PasswordAuthentication no UsePAM no If I set a password for the users, the public key auth works without any problems. Could anyone tell me what I'm missing here?

Wireless connection issue - athero 9300 pci wireless card
by Xianyi 10 Oct '13

10 Oct '13

Hi all, I am new to CentOS. I built myself a desktop with an additional PCI wireless card 'TP-LInk WPN3800', which I have checked needs an ath9k driver. * **04:00.0 Network controller: Atheros Communications Inc. AR9300 Wireless LAN adaptor* Following the wireless connection tutorial on CentOS wiki, I have both kernel-devel 2.6.6 and ath9k installed. Then I tried * $ modprobe ath9k *but nothing happened. Then I input *$ service NetworkManager start $ chkconfig NetworkManager on *to access the Network Manager and no wireless connection options appear. I do not think it is a big problem for you guys, but I am really a beginner. Please share me some solutions for that. Thank you!

mdraid strange surprises...
by John Doe 10 Oct '13

10 Oct '13

Hey, I installed 2 new data servers with a big (12TB) RAID6 mdraid. I formated the whole arrays with bad blocks checks. One server is moderately used (nfs on one md), while the other not. One week later, after the raid-check from cron, I get on both servers a few block_mismatch... 1976162368 on the used one and a tiny bit less on the other... That seems a tiny little bit high... I do the whole repair+recheck and it is back to zero. For brand new arrays, I am not very happy about the way mdraid seems to function (with the manual/croned checks, repairs, checks, checks, repairs, checks...) I will have to see next week how high the mismatches reach... Since my desktop is a RAID1 mdraid on 2 disks, I decided to have a look for fun... Apart from some low count mismatches, I did not have many problems... Did the whole check+repair+check on 3 mds and had a look at mdstat... md0 : active raid1 sdb1[1] sda1[0] 200704 blocks [2/2] [UU] md1 : active raid1 sdb2[1] 2048192 blocks [2/1] [_U] md2 : active raid1 sdb3[1] sda3[0] 2048192 blocks [2/2] [UU] md3 : active raid1 sdb6[1] sda6[0] 6144704 blocks [2/2] [UU] md4 : active raid1 sdb8[1] sda8[0] 2048192 blocks [2/2] [UU] md5 : active raid1 sda7[0] 4096448 blocks [2/1] [U_] md6 : active raid1 sdb5[2](F) sda5[0] 131074176 blocks [2/1] [U_] md7 : active raid1 sdb9[1] sda9[0] 340722432 blocks [2/2] [UU] It seems like I have some healthy volumes, some "failed partitions", and even some "missing partitions"... on both disks... And mdraid seems not alarmed about it... 1. Is there something to activate to get some kind of mdraid warnings? In /var/log/messages I cannot find any alarming message. 2. How to recover? Reboot? Or should I just mdadm --add the missing ones and --remove then --add the failed ones? Thx, JD
