I have CentOS 7 installed with GUI (Gnome 3.8.4) and I'm trying to follow the guide at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/s1-users-configui.html it speaks of "System > Administration" from the GUI or "system-config-users" from the command line, but I can't find either?

hi all, I've inherited a server with CentOS 6.4 the VNC Server starts up with the OS and its screen resolution is set to 800x600. I found that I can set the resolution by specifying the -geometry switch, but I can't find where the call to start the vncserver is set in order to change it. I know that it's not in /etc/xinetd.d (the only file there is rsync) here are the contents of

does adding a /lib/systemd/system/{unit}.service all I need in order to add a service? see example file for Tomcat that I plan to add at https://github.com/wichtounet/systemd-unit-files/blob/master/tomcat.service are any special permissions required for that file (execute)? TIA, Igal

hi all, I've inherited a CentOS 6.4 machine that runs VMWare Workstation 9 which in turn hosts a Windows SBS 2011 guest. the problem is that the Windows guest keeps crashing, and I have no idea why. it was working fine for a while but recently started crashing after a day or two of operation. as a total Linux/CentOS noob, I have some questions: 1) is it safe to assume that since the guest

hi all, after many years of working almost exclusively with Windows servers I am trying to switch to CentOS. I have a couple of books which were written for CentOS 5, but many (basic) things do not apply to CentOS 7 anymore, which is very confusing. Internet resources suffer from the same problem. for example, one of the books shows a Services configuration tool, which should be accessible

Hello all, I'm trying to modify a single column of a data frame to remove randomly half of the values. I want to do it within a function, but can not assign the modified column back into the data frame. It was easy and successful without a function, so I suspect the problem is the call of the single column within the function. removedata<-function(datafull,var.removed) { attach(datafull)

Thank you ! I run your code. It have a graph with time(date) on x-axis. Thank you very much! Well, Would you like to do me a favor again? Most of times, the x-axis time data is lasted about 3 months.

Thank you again. I am deploying Liberty Neutron, according the official document, there are two NIC at least, but my physical machine has only one. Someone suggested me I could create a vlan interface, then everything would be ok. Until now, though I created the vlan interface, it can't attach to the Internet. Could other methods created virtual interface instead of vlan interface? Thanks

Thank you very much for reply. Our test team insists on simulating network failure by using ifdown instead of just unpluging the cable. I have to modify the event script 10.interface. When noticing a NIC failure, CTDB just marks the NIC down and do not try to pull it up. It seems to work fine. -----邮件原件----- 发件人: Martin Schwenke [mailto:martin at meltin.net] 发送时间: 2016年9月18日 18:49 收件人: Weidong

or you can just add a built-in function in c frontend "readadcreg()" and emit it as llvm.zhu.readadcreg(), so you can just call the built-in function to get the adc register value.
