C7.4 and sshd restart problem
by Alessandro Baggi 06 Nov '17

06 Nov '17

Hi list, Some days ago I updated my centos 7.3 to 7.4 on a dell server. After this update I noticed a strange behaviour by sshd. I noticed this problem because trying to connect to ssh I got connection refused or high latency between connecting and password req. So I noticed that sshd will be restarted every ~2 min. >From log I get this: Received signal 15; terminating Failed to start OpenSSH server daemon Unit sshd.service entered failed state sshd.service failed sshd.service holdoff time over, scheduling restart ....and sshd restart. This happens so fast that if I run systemctl status I can't get the failed status. Logs does not help also in debug facility. There is not any cronjob that kill sshd. I tried also to change some basic sshd_config directives and when running systemctl restart sshd it hangs until I type crtl-C and from log I see that sshd is restarted. In sshd_config there aren't errors and the config is the same since 2016. On another machine in the same network I have the same configuration and same software installed (replica with native c7.4) but the problem does not occurs. I checked also md5 of relative server /usr/sbin/sshd and they match. Selinux is disabled and using non standard port. I notices also that if I'm connected to sshd and sshd crashes/restart my current session is not killed. I have not stopped and restarted sshd because this is a dedicated server and until my provider does not attach a kvm switch I can't do other tests. I will try also to stop sshd and run from console using debug hoping that helps. What I can check to know the reason of this behaviour? This is sshd problem or other? Thanks in advance.

How to detect botnet user on the server ?
by marcos valentine 06 Nov '17

06 Nov '17

Hello guys, Whats is the best way to identify a possible user using a botnet with php in the server? And if he is using GET commands for example in other server. Does apache logs outbound conections ? If it is using a file that is not malicious the clam av would not identify.

Re: [CentOS] HP laptops with CentOS 7?

Hi yeah, it's just a normal USB dongle, and it's supported by the Linux Kernel, that's why I tried it. I have tried other USB dongles with Linux before and failed. This one was plug and play.

CentOS 6 P2V alternatives?
by Sorin Srbu 06 Nov '17

06 Nov '17

Hello all, This week I've tested out a few ways to do a P2V on a rather ancient CentOS 6 server, in order to move it to a Hyper-V host. So far my tests have failed rather spectacularly. Initially I was set on doing a simple dd-routine, but was told that the server cannot be taken off-line as it's being used daily, so had to look for other solutions. The disk setup is currently as follows: Three 500 GB sata-disks, sda, sdb and sdc, are used to build a software raid called md0. No LVM's here. Sdd is a 120 GB drive, with partitions for boot, swap, home and /. No LVM's here either. The farthest I've gotten is with the Rear solution. http://relax-and-recover.org/ The backup goes well, but recovery for some reason fails to create initramfs with all the installed kernels, as well as failing with an error saying it cannot find /boot/grub, after which the recovery terminates. Virtualizing systems like this is kinda' new to me, having it done on Windows only, and I'm not really sure how to proceed when it's a CentOS system in question. The physical CentOS-server runs a few license managers and nfs-shares that server molecular modeling software, that are rather intricately set up (I inherited this server some fifteen years ago). Are there any easier ways to do a P2V at all? -- BW, Sorin ----------------------------------------------------------- # Sorin Srbu, Sysadmin # Uppsala University # Dept of Medicinal Chemistry # Div of Org Pharm Chem # Box 574 # SE-75123 Uppsala # Sweden # # Phone: +46 (0)18-4714482 # Visit: BMC, Husargatan 3, D5:512b # Web: http://www.orgfarm.uu.se ----------------------------------------------------------- # O< ASCII ribbon campaign - Against html E-mail # http://tinyurl.com/ascii-ribbon-campaign # # This message was not sent from an iProduct! # # Please consider the environment before printing this email. # Join the campaign at http://thinkBeforePrinting.org # # MotD follows: Spare yourself many hard falls; don't jump to conclusions
