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

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

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

vpn - xl2tpd and routing to a net?
by lejeczek 31 Mar '16

31 Mar '16

hi everybody I'm having a, I'd like to think a "regular" VPN with IPsec/xl2tpd and it all works OK, except.. One thing that I never needed but now I do and I wonder.... is it my iptables, or/and routing or maybe VPN server config..? vpn clients with established tunnels can get to VPN server's NICs/IPs but cannot get through to the net behind the server. Well... they can, but only if on a host (eg. 192.168.2.33) on VPN server's net I do: route add -host 192.168.2.10 gw 192.168.2.100 # 192.168.2.10 is VPN client I thought this I'd not need since that local net (eg. 192.168.2.33) use VPN server's 192.168.2.100 as the default gw. is it by design and nature of that VPN solution it works this way or I actually have missed/messed up something? I hope the latter and adding routing on per "to host" basis is redundant. many thanks

Laptop SCSI capability supported by CentOS 7
by Lamar Owen 16 Mar '16

16 Mar '16

I'm looking for a well-supported ExpressCard or PCMCIA/CardBus SCSI card that can do at least FastSCSI (Narrow, Wide not necessary) that is supported by CentOS 7. I have an Adaptec SlimSCSI 1460D, but it doesn't seem to be supported (it's previously supported by the aha152x driver). Any ideas are welcomed, other than 'just use a desktop.' I am not sure a USB or Firewire to SCSI bridge will work for what I need, which is connection to an audio-capable DDS2 drive (SGI Firmware Seagate/Conner/ArDAT Peregrine 4326 that is from an SGI system). Yeah, I know I can use DATman on IRIX (I have a pair of O2's and a purple Indigo2 w/ SolidIMPACT), but going forward I'd like to use my laptop.

power management / tuned following external power source
by Karanbir Singh 08 Mar '16

08 Mar '16

hi, twice in the last week I've been caught out where the laptop was running tuned with 'throughput-performance' profile on the work table, and I walked away, carried on working - and had the battery run flat in just over an hour. Compare this with tuned running the 'powersave' profile - will usually take the battery through to 3hrs+ - and if i just totally turn down the cpu's in the powersave mode, I can get 5 hrs+ on the x1 carbon gen2 laptop I've got. So what I am wondering is if there is an easy way to have the tuned-adm reset profiles based on external power source. If I'm at the work table and plugged in, run with throughput-performance mode, and if the external power is disconnected, run in powersave mode ? I've had, admittedly a brief, look and found nothing obvious. Has anyone else run into this before ?

Latest version of kate editor
by H 07 Mar '16

07 Mar '16

I have installed the kate editor on Centos 6.7 but it seems to be a very old version, 3.3.4, installed as part of kdesdk. On Centos 7 I can simply run 'yum install kate' but, alas, not on Centos 6. What is the recommended way of updating kate on Centos 6? Thank you.

Problems with CentOS 7 and X w/ nvidia
by m.roth＠5-cent.us 03 Mar '16

03 Mar '16

Ok, here's a bit more on the issues: I see in Xorg.0.log that it appears to have loaded the NVidia drivers I built from proprietary. But, and this may, or may not be significant, the user's home directory is, of course, NFS mounted. And his old machine that dies was running CentOS 5. Is it possible that some of the gnome settings are breaking things with CentOS 7's default gnome? If so, what kinds of things should I be looking for? mark

Problems with ProxyPass to a local ip (using SSL)
by C. L. Martinez 03 Mar '16

03 Mar '16

Hi all, I am trying to setup an apache virtualhost under CentOS 6.7 that needs to redirects requests from port 444 to port 5100 in its local ip. But I am doing some mistakes because every time I'm receiving a loop error. My actual httpd's config for this virtualhost is: NameVirtualHost 192.168.1.5:444 <VirtualHost 192.168.1.5:444> ServerName myweb01.local.domain ErrorLog logs/ssl_error.log CustomLog logs/ssl_access.log combined CustomLog logs/ssl_request.log "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b" LogLevel info SSLEngine on SSLProxyEngine On SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!ADH:!EXPORT56:!EXP:!eNULL:!aNULL:RC4+RSA:+HIGH:+MEDIUM:!LOW:!SSLv2 SSLCertificateFile /etc/httpd/certs/server.crt SSLCertificateKeyFile /etc/httpd/certs/server.key ProxyRequests Off ProxyPreserveHost On ProxyPass / http://192.168.1.5:5100/ ProxyPassReverse / http://192.168.1.5:5100/ RequestHeader set X-Forwarded-Proto "https" RequestHeader set X-Forwarded-Port "444" RewriteEngine On RewriteRule ^/(.*) https://myweb01.local.domain:444/$1 [R,L] </VirtualHost> As you can see, I need to do a redirection to port 5100 from 444 port and protect it using ssl. I've configured iptables rules to drop connections to port 5100 directly: *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 444 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT Any idea how to accomplish/resolve this? Thanks. -- Greetings, C. L. Martinez
