Dear All, I selected CentOS5 in my works and installed them in two DELL PowerEdge1950. However, a trouble blocked me during the machines run after two days. The machines crashed and the syslog said it got the following messages: ------------------ part dump of /var/log/messages ---------------------- .....

I am looking at using CentOS to use as a network recorder to enhance our security analysis. During my research I found that the linux kernel (not CentOS specific) has a bad problem of dropping packets on gigabit connections. This problem exists even on a dual xeon system with 1gb ram using a minimal install. Once I found the ethereal performance wiki I realized the problem was not in the system

Hello, I have paid attention to the issue about the X509-based certificate support in standard openssh. Because I also need the support of X509-based certificates in my project, and also I have developed specific version of openssh to pass the proxy certificate from client to server. But I used the PAM module to verify the proxy and authorize the accessors. I wonder whether current support in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys, been trying the x509 patch for ssh from Roumen, it works great. However, I can't figure out couple of things, and been trying to solve it for couple of days already. I'am using OpenSSH_4.7p1-hpn12v19, OpenSSL 0.9.8g with 6.1 version of your patch. The serverside hostkey is configured correctly, to present x509v3-sign-rsa dynowork

Hi, I have recompiled my kernel and updated it to kernel-2.6.27. However, I found there are no more than 1G disk space left for my jobs. How can I free my disk space but in the same time keep all the compiled kernel modules (*.ko files) here? Can I remove the *.o files created by kernel compiling? Are there any commands to help me achieve this? Thanks a lot, Ian

Dear all, The cpufreq modules have been distributed in Centos. But recently, I met a problem when I tried to test the power-related applications.

Hi,All I searched from git-log, and found that until now we have vhost TX zero-copy experiment feature, how about RX zero-copy? For XEN, net-back also only has TX zero-copy, Is there any reason that RX zero-copy still not implemented? Thanks!

Hi all, Just tested the new CentOS 6.8 release on a few VMs and a physical box and got a kernel panic. Is it just me, or anybody else as well? Just fishing for now, will look into the issue more thoroughly later today. -- BW, Sorin ----------------------------------------------------------- # Sorin Srbu, Sysadmin # Uppsala University # Dept of Medicinal Chemistry # Div of Org Pharm Chem #

Hi everybody, I got a strange error message when I used the openssh. When I run it with debug mode, like this: # /usr/local/sbin/sshd -d I can open the session via ssh command. However, when I run with daemon mode, the ssh client was closed down and threw out the following message: debug1: dispatch_run:dispatch done debug1: Authentication succeeded (keyboard-interactive). debug1: channel 0:

Hi, I make a mistake so that crash the whole system which can not boot from hard dist. But I am sure if I can access that hard disk, I can fix it. Now, the problem I met is how to boot from other media such as CD and then mount the hard disk so as to fix the mistake. Could anybody give me some advices, thanks in advance. Ian

Hi all, I have modified the openssh and added a new authentication module in it. But I don't know how to compare the performance between the modified version and original version. Are there any benchmark designed for openssh? Or, what applications are classic to openssh and should be recommended to do this kind of tests? Regards, Ian

Hi, I'm new to the list. I've replaced grub by extlinux to multi boot my system. Now, I can't manage to boot one of my systems. I have 5 hard drives, 3 of them being part of a raid0 array, and one of them being here for backup purposes (can be removed). So the total 'logical' drives number is 2. First drive: - primary partition holding a rescue Windows XP system (ntfs) -
