Hi list (and happy new year), I'm experiencing some troubles using Samba (4.1.17 debian version) over VPN. Basically we've following setup : PC === LAN ===> VPN (WAN) ==== LAN ===> Samba file Server Copying big (say > 1MiB) files from PC to Samba file server almost always ends up with a NT_STATUS_IO_TIMEOUT error (or "a network error occured" if trying to copy from

All, This is a fresh, un-f#$ked-with OpenSUSE install after adding the Tumbleweed repository and doing a dup. I installed the Hypervisor with Tools for which it prompted me for Xen or QEMU and I chose Xen. No bridge was made. When I go to create a fully virtualised machine, it nao has the error: Error: Device 0 (vif) could not be connected. Could not find the bridge, and none was specified.

Hi, What's the correct way to disble TSO (TCP Segmentation Offload) in RHEL5? I have tried adding those options in ifcfg-ethX configuration file: # grep ETHTOOL /etc/sysconfig/network-scripts/ifcfg-eth0 ETHTOOL_OPTS="tso off" And also with: ETHTOOL_OPTS="-K eth0 tso off" But when restating the server TSO is enabled: # ethtool -k eth0 tcp segmentation offload: on As a temporary solution, I'm executing this command in a start script: /sbin/ethtool -K eth0 tso off But I think it ca...

Anyone know off the top of their head the "right" way to hard set a link automatically to 100Mbps Full Duplex, etc using the ifup or ifcfg files? Don't see options in the scripts that might cover this, but maybe there's a more elegant way to do it than to do something in rc.local or hack up the ifup files myself... Ray

Hello, I have been using xen under open-suse 11.4 for almost half an year now. This week I had to reformat the provider and so I did install everything again (now there is a dual boot and microsoft windows server 2008 installed on the first half partition of the disk) again open-suse 11.4 and xen. I do start the xen kernel at grub but when I try to connect and/or creat a new domU the folling

I figured out how to force 10 megabit full duplex on my ethernet interface. The trick is i need it to stick in case of a reboot so i don't have to reforce it. I have not been able to figure that one out yet. I have not found it in the man's or google yet. If someone could point me in the right direction i would be much obliged. -- My "Foundation" verse: Isa 54:17 No

Hi, i'm currently installing a SLES 12 64bit system. libvirt-client-1.2.5-13.3.x86_64 and libvirt-daemon-1.2.5-13.3.x86_64. Formerly I created my vm's (KVM) using a traditional bridge in my host systems, mostly SLES 11 SP3. But with SLES 12 I don't succeed. I can use the macvtap device in the host, but I like to be able to communicate between host and guest. Is the traditional bridge

Hi, Recently I'm noticing an interesting issue. My CentOS servers are trying to send logs to a logging server via 514/udp, however I'm not receiving anything. I did the following on CentOS *tcpdump -vvv -nn udp -i esn160 port 514* In another session on the same server: *nc syslog-server -u 514* tcpdump started to show me messages like: *[bad udp cksum 0x3ce9 -> 0xb0f5!] SYSLOG,

You can configure the ETHTOOL_OPTS option in the ifcfg files to automatically assign settings on startup. Regards, Simon

Everyone, I have not been able to get ether-wake to work waking up other centos 7.6 machines after the upgrade to Centos 7.6. Has anyone else had this problem, and if so any luck with a fix? Greg Ennis

Greetings, I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that the speed and duplex settings are 100 Half Duplex. I tried to change the duplex settings to full, but no success. I got the error message "Cannot get current device settings: Operation not supported". Does anyone else experience this issue?. Below is the error message and some more details about my box.

I have a server with dual nic's running centos 5.2 1 nic connects to the cable modem, which has 15m d and 2m up, but speed tests barely come back at 5mb down including road runner's internal speed test. I hook up my laptop to the same modem, same port, using the same cable and I get 17mb down. I have ruled out iptables, nics (because same result on both nics), cables, cable modem(with

The short version. Copying over SFTP to our centos boxes maxes out at 2MB a sec. The Question: Is there some sort of speed limitation somewhere in the ssh/sftp daemon? Does anyone have any idea why this could be happening? The long version We have centos 4.6 installed on 2 different machines, different hardware, different nics. Even on 2 different subnets. I've tried different switches,
