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

Hello!

Broadcom BCM4313 support broken with kernel 2.6.32-573.7.1.el6.centos.plus.x86_64?
by wwp 24 Aug '16

Hello, I noticed that with latest kernel (2.6.32-573.7.1.el6.centos.plus.x86_64), my laptop's Wifi doesn't work, whereas with previous kernel (2.6.32-504.30.3.el6.centos.plus.x86_64), it works fine. Is this a known issue or did I miss something new? BTW, `lspci` says: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01) Regards, -- wwp

Any further developments on CentOS7 for i386?
by Kay Schenk 22 Jun '16

22 Jun '16

Well I haven't tested out the CentOS 7 for i386 yet as sent in the message of 06/02-- https://lists.centos.org/pipermail/centos-devel/2015-June/013426.html Nor have I seen any additional information. So how is this going? I'm almost ready to jump in as I would really prefer to be on Gnome 3. -- -------------------------------------------- MzK “The journey of a thousand miles begins with a single step.” --Lao Tzu

Google Chrome and CentOS 6?
by Sorin Srbu 19 Apr '16

19 Apr '16

Hi all, Just recently I started getting the dreaded message about my CentOS 6.7 x64-installation wasn't going to be supported anymore by Google Chrome. "This computer will soon stop receiving Google Chrome updates because this Linux system will no longer be supported." Doing some google searches I found this; http://superuser.com/questions/1011832/this-computer-will-soon-stop-receivi… Which in itself wasn't too uplifting... Following the suggestion about installing Chromium instead worked, but it seems to be stuck at an ancient version of the browser. Recompiling the available Chromium source is of course an option, but not for me. Not unless there are step-by-step guides doing it. There was a rather long and somewhat heated discussion regarding Chrome on CentOS a while ago. Was there any real conclusion about Google Chrome on CentOS and how to get around this problem? Are the views on this matter still infected? I'm not looking forward to go back to the sluggish Firefox. 8-/ -- 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 ----------------------------------------------------------- # () ASCII ribbon campaign - Against html E-mail # /\ # # 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: # "You guys got something against spam?" -de Vriess, in Alien^4

Openshot 2.x (beta) on C7??
by Fred Smith 08 Apr '16

08 Apr '16

I'm interested in trying out the new OpenShot beta (2.06) on CentOS 7. Openshot requires Python3. so I look at available packages where I find a bunchof python3 packages as well as python34 packages. I'm assuming that python34 is version 3.4 of python, while python3 is some other 3.x version. Can anyone here explain to me what are the differences, any compatibility across these versions, and how to tell which I need for OpenShot? Thanks in adva ce!

Hi List, Does anyone know why the above URL is still using TLS V1.0. I can't connect to it unless I enable TLS V1.0 which I was under the impression that it should not be used anymore. Thanks for any enlightenment. Steve --

Is there a way to detect/validate DHCP static IP assignment?
by David Copperfield 01 Apr '16

01 Apr '16

Hi, We have tens of networks(VLANs) in data center with a central Linux DHCP server. each network has their router to do the DHCP relay. So, the DHCP server's configuration files has tens 'subnet' statements. Because PXE booting is standard in whole data center, there are also thousands of static MAC-IP mapping 'host' statements in dhcp configuration. The big challenge with a central dhcp server is how to detect typo in the thousands of MAC-IP 'host' statements? -- a single char/digit typo here will fail a PXE booting or download wrong post-installation snippets. Is there a tool to validate all 'host' statements from another Linux box? I tried nagios check-dhcp plugin, with a series of real MAC addresses(for hosts in other different networks). Surprisingly, the IP address came back were not the static IP addresses in 'host' statement, but dynamic addresses in the pool defined for this particular network (where I ran check-dhcp from). check_dhcp was run with the following arguments: /usr/lib64/nagios/plugins/check_dhcp --verbose --server=<my_dhcp_server> --interface=eth0 --mac=<real_Mac_for_servers_in_diff_networks> --unicast remove --unicast doesn't help but just see more DHCP replys. Interestingly, with a same MAC address, and the above same command, from two Centos boxes on different network there will be different dynamic IPs! instead the static IP defined with 'host' statement. So, how can we validate static IP assignment? Thanks. Best,David,

Anyone running CentOS 7 here in HP Blade BL620c Gen 7 when I use the live DVD the network card can detect and I can use without issue however when I install the CentOS 7 with Server GUI.

CentOS 7, rsync problem
by m.roth＠5-cent.us 01 Apr '16

01 Apr '16

Oddity: rsync *should* be recursing, and dealing with very large number of files. It works, going from box a to box b. But when I try to back b up to c, it fails, 100%, complaining of "out of hashtable space [sender]". I've tried adding -r, and changing --delete to --delete-delay, and no joy. All boxes are current, or fairly current, CentOS 7. Anyone got any thoughts on the matter? mark -- I *hate* nixspam
