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.

Hi there, I'm trying to run 'reposync' against centos-extras and am getting an error like this: python-itsdangerous-0.23-2 0% [ ] 0.0 B/s | 0 B --:-- ETA python-itsdangerous-0.23-2.el7 FAILED python-itsdangerous-0.23-2 0% [ ] 0.0 B/s | 0 B --:-- ETA python-itsdangerous-0.23-2.el7.noarch: [Errno 256] No more mirrors to try. Is that package missing from the repo for some reason? Is the repo metadata outdated? Thanks, -- Barak Korren RHV DevOps team , RHCE, RHCi Red Hat EMEA redhat.com | TRIED. TESTED.

Re: [CentOS] HP laptops with CentOS 7?
by Gary Stainburn 06 Nov '17

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

Incorrect characters in Chinese font
by H 04 Nov '17

04 Nov '17

I frequently exchange e-mails, read and write documents and visit Chinese websites although the language of my computer is English. As I was translating a Chinese document yesterday, I had three characters I was not able to translate and after much hair-pulling realized to my surprise that they may be incorrectly drawn in Centos 7. These very characters in the same document were drawn correctly on my Android phone... As none of the characters are uncommon, I am very surprised. Could this be a Unicode issue? How does one report this in CentOS? The usual bug tracker?

low end file server with h/w RAID - recommendations
by Gary Stainburn 04 Nov '17

04 Nov '17

I'm just about to build a new server and I'm looking for recommendations on what hardware to use. I'm happy with either a brand name, or building my own, but would like a hardware RAID controller to run a pair of disks as RAID1 that is actually compatible with and manageable through Linux. Any recommendations would be appreciated. Gary

modestly priced laptop for C7
by Fred Smith 03 Nov '17

03 Nov '17

I'm looking to replace my (old, creaky) netbook (Acer Aspire One D255e, a screaming dual core 1.6 GHz Atom, and a whole 2 gigs of RAM) with something faster but not too large. Sometimes (usually) the netbook is painfully slow. Something like a hi-res 14 (or 15) inch screen (full HD), minimum of 4 gigs RAM, HD of a half terabyte or bigger. I'd like to not have to go over 600-700 dollars, so I know my choices are somewhat limited if I want to avoid the 400-500 dollar windows 10 junk^H^H^H^Hsystems from BJs, etc. Something with a quad-core processor, and all hardware works with C7. I've glanced at Lenovo Thinkpads on amazon where there are several "factory refurbished" ones with similar specs to what I mention above in the $500-700 range, but I don't know if they're any good or not I'm open to suggestions from any/all of you! thanks in advance!

Kickstart ksdevice question
by Mark Haney 03 Nov '17

03 Nov '17

This should be easy to answer (I hope). We routinely kickstart boxes to use for managing our customers RADIUS/DHCP configurations (along with other things). We've had a C7 kickstart in place since I built one in May and are finally starting to roll it out for new installations. But, I'm curious as to what ksdevice= actually does. With the C6 we routinely used ksdevice=eth0 since we ship boxes with two NICs and knew interface 1 was always eth0. With C7 comes the interface naming convention changes and that's where questions have arisen about that option. It's been set as ksdevice=eno1 since I know these servers name the interfaces with the eno# convention (integrated dual-port). A coworker of mine insists on setting it ksdevice=enp2s0 which doesn't seem to work like it should (though, it could be a fault netinstall image, I'm not sure yet). In all honesty, we'd prefer to keep the eth# convention for C7 like C6. So, my question is, does setting ksdevice=eth0 dictate to the system the names of the interfaces? Is that just a name for the install process and the kickstart script assigns names? (We have the kickstart script setting them as eno1 and eno2, btw.) I've googled this to no end and haven't found a satisfactory answer. So, I'm hoping someone with more KS experience than I can explain it. -- Mark Haney Network Engineer at NeoNova 919-460-3330 option 1 mark.haney(a)neonova.net www.neonova.net

/usr/bin/x0vncserver large blocks on screen at times
by Jerry Geis 03 Nov '17

03 Nov '17

I use this vnc program to remote into my station. (C 7.4) When I do, about every 5 to 10 seconds a big solid block appears on my screen. About six inches long and 3 inches wide. it quickly then goes away. I use the realvnc.com viewer when I do this. Is there some setting that would help with this ? Jerry
