Memory vs. Display Card
by Rick 28 Oct '25

28 Oct '25

Since memory has become quite cheap lately I decided to move from 2 GB to 6. When I installed the memory every thing was fine until I went to run level 5. At that point the screen turned to garbage and the system froze. Is there a way to fix this so I can use the memory I bought? Do I need a new display card?

SSD for Centos SWAP /tmp & /var/ partition
by Keith Roberts 03 Sep '25

03 Sep '25

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So I had to install another (WD) drive, and repartion it and rebuild my RPM package database, from the backed-up Packages file. That seems to be all OK now. I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat. Here's a short video of a laptop fitted with a SSD drive booting macOS, compared to a similar laptop booting from the standard HDD. The laptop with the SSD boots and loads some apps in 28 seconds. The other one takes twice as long. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro_6G/?utm_source=t… Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

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

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

Badlock bad luck
by Bob Smith 23 May '16

23 May '16

I had exactly the same problem. Your workaround fixed me too. With the new samba packages my samba\logs are full of errors. If I temporarily disconnected the PC client NIC cable, and logged into the domain using cached credentials, then I could get past the problem. But, you helped me greatly with this posting. I wasted hours checking Windows updates - useless. We still need the new configuration settings for our conf file to workaround this problem.

I'm seeing the exact same behavior in my environment (NT4 PDC, not AD). I had to downgrade samba get systems working again. The full error message is: "The trust relationship between this workstation and the primary domain failed". Did you have any luck finding a solution?
