Installing support for Chinese text in Centos 7
by H 18 Jul '17

18 Jul '17

I have just done a minimal installation of Centos7 followed by X Windows and the Mate desktop on a workstation. Although the default language is English, I would like to be able to write Chinese text in various applications. I seem to remember this was very easy to do in Centos 6 and Gnome: possibly only requiring only a simple 'yum groupinstall "Chinese Support"' after which I could use iBus to switch between languages. This does not seem to work in Centos 7. Suggestions? Thank you.

CentOS 6.8 and samba
by isdtor 23 May '17

23 May '17

Other than the original 6.8 release version 3.6.23-33, samba has not been functioning correctly for me under 6.8. The symptoms are that about 6-7 days after starting the server, users start complaining that they can no longer open documents on their share. Upon inspection, I find several, sometimes nearly a dozen smb processes owned by a single user, on top of those run under root. Stopping the service does not stop these processes. They are only killable with SIGKILL, and after that, a service restart does not result in a functioning service, i.e. connections are refused, which can be verified easily with smbclient. The only cure is a server reboot. And it is not the same user id every time it happens. Useful logs of any type are not available. I have tested -35 and -36, both show the same behaviour. This is a production server and I have no time for tinkering; downgrading to -33 and blocking samba updates is the only workaround for now.

How to enable the svm cpu flag inside a vm?
by Leonard den Ottolander 03 Apr '17

03 Apr '17

Hello, I'm trying to get the Android Emulator to run inside a kvm vm on CentOS-6. Apparently the latest Android Emulators cannot run without hardware acceleration so I am trying to get the vm to see the svm cpu flag. Host: $ grep model\ name /proc/cpuinfo | sort -u model name : AMD Phenom(tm) II X4 965 Processor $ grep svm /proc/cpuinfo | sort -u flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt npt lbrv svm_lock nrip_save $ cat /sys/module/kvm_amd/parameters/nested 1 I have tried copying the cpu options (Opteron_G3) in the host cpu configuration and setting the svm flag to either "model", "required" or "force" to no avail: $ ps waux | grep qemu qemu 7962 7.2 21.9 3722092 2680668 ?

I want to connect to a l2tp server from centos.
by Eliezer Croitoru 22 Mar '17

22 Mar '17

I have a server currently connecting to a pptp remote server. This server(lns\lac) has the option for pptp connections and l2tp connections. The l2tp connections are not using ipsec encryption at all. I have seen couple guides\tutorials on the internet: - https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_on_CentOS_-_Red_Hat_Enterpris… - https://wiki.archlinux.org/index.php/L2TP/IPsec_VPN_client_setup But all the guides that I have found are using ipsec with "secret". On ubuntu there is a gui applet that helps setting these kind of connections up but I am working with a CentOS server and not Ubuntu desktop. If someone used l2tp the same way I want to use on CentOS 7 please give me some advice. If you have a guide which might help me I will be more then happy to see this one. Thanks, Eliezer

Dear All, Mark has problem sending mail to centos(a)centos.org list... He has trouble with flash plugin on CentOS 6, please, take a look at his e-mail below. I'll try to see what I can do to help, but what I can do definitely is no match to Experts on this list. Thanks in advance! Valeri ---------------------------- Original Message ---------------------------- Subject: The CentOS list From: m.roth(a)5-cent.us Date: Mon, January 30, 2017 3:11 pm To: "Valeri Galtsev" <galtsev(a)kicp.uchicago.edu> -------------------------------------------------------------------------- Hi, Valeri, I've tried, twice, to post to the list today, and they neither show up, *nor* do I get a blocked message - they just go to /dev/null. The second was just a test, the first was asking if anyone else was seeing, with CentOS 6 (updated) flash-plugin crashing every 10-15 min. And there's no downgrade for it. mark ++++++++++++++++++++++++++++++++++++++++ Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ++++++++++++++++++++++++++++++++++++++++

Systemd debug logging turned on in CentOS 7
by Thomas Eriksson 28 Feb '17

28 Feb '17

Hi, I noticed that some, but not all, of my CentOS 7 machines have these kernel parameters for turning on systemd debug level logging added to the grub.cfg file. systemd.log_level=debug systemd.log_target=kmsg The parameters are *not* in the /etc/default/grub file, so if I rebuild grub.cfg with grub2-mkconfig, they disappear. I am a bit puzzled over how they got introduced. Has anyone else seen this? thanks, Thomas

sshd Match Group directive problem
by Bernard Fay 28 Feb '17

28 Feb '17

I try to set up two "Match Group" directives in sshd_config. I have an LDAP server. All users including admins are part of the LDAP group users. The admins users are also part of the LDAP group wheel. For example: [~]groups admin1 admin1 : users wheel [~]groups users user1 : users On a client server to LDAP, I try to configure two "Match Group" directives in sshd_config as follows: Match Group wheel some keywords... Match Group users some keywords... The problem is that even if a user is a member of LDAP group wheel, the "Match Group wheel" directive is skipped in favor of the "Match Group users" directive. Is it possible to have two "Match Group" directives as I like to do it? If yes, what is wrong in my configuration? Thanks,
