similar to: xhost: unable to open display

I have googled, read the man page, and such. What I am trying to do is install applications to a NFS mounted drive, where the libraries and everything are locally installed on that filesystem so that it is portable across servers (I have over 100 servers which each need specific applications installed via yum and we do not want to install 100 copies). We tried the yum relocate and it was not

I have a large set of Dell 620 blades fully populated with memory and duel socket CPUs, Centos6.4 image. I have a kickstart that I am using to pxe boot 36 blades. I have two internal drives which are raid1 (two disks formed into one, no redundancy), not san attached In the first set, 9 successfully completed. 7 more built correctly after trying another pxe boot. 2 just wont pxeboot In the

Hi, I am running centos6-5 on dell620 blades. mirrored local root drives several (including home) mounted filesystems. The other blades are working fine. Top indicates the server is running 1% cpu, and very little memory (idleing) There is no error in the messages file There is no amber lights on the server. When I log into my server it is fine, on my remote mounted home directory. When I cd to

I have an intermittent problem with my Dell blades, out of 80 blades 69 of them kickstarted Centos 6 fine using PXE The other 11, I get a c0t0 not found error (indicating it is not finding the local disk on the blade). I can remote mount the iso image and do a basic install of centos on these blades, but when I go to do a pxe boot it gives me that error again. I have googled the issue and

I am trying to run 'xhost +' on CentOS 8 (such that I can grab a screen shot) but its not letting me. On boot of X I run the "xhost +" then later with SSH into hte box - I run export DISPLAY=:0.0 gnome-screenshot -f jj.png and I get the cannot open display message. This works on the older CentOS 7. What is the magic for C8? Thanks, Jerry

Hello list, In the past we have instructed users to perform 'xhost +' from their centos desktop, then set the DISPLAY variable on a remote computer to forward their display back to the desktop. This does not seem to work on centos 6 - but it did work in centos 5. It works from a vnc session on the desktop machine, but does not work from the local desktop. We would typically use a display

I am looking for opinions and personal experience on CentOS7 for both grid and virtualized web environments. I am currently on CentOS6.5 in a production environment. I am about to add about 50 more servers to my grid and am trying to identify the advantages and disadvantages of going to CentOS7. The good part is, that I have some tolerance for backing out and installing CentOS6.5 if 7 does not

Hi, I am still trying to get kick-start centos in my vmware5 because pxe cannot find the pxe server. I do not control the dhcp or pxe server. I have both my kickstart file and my iso image for centos6.5 on my vmware datastore, but am trying to run my kickstart file from VMware guest. Can I tell the command line to run from the datastore in VMWare? Or must I convert my kickstart file to a

I am a bit baffled on this. We recently rebuilt all our servers to CentOS release 6.8 (Final) from a prior 6.x centos release. We ran into a couple of problems such as Java not working (just had to yum install java). It was installed, but unable to create a java machine, until I yum install java solved the problem. But now a user (the big boss) is receiving xrdp errors. And it appears

Hi, My bosses are running into an issue, where we type "ls" on a nfs mounted filesystem, and files that are there are not listed... I thought it was pilot error until my big boss showed me... but we can vi the files, we can access them via other means if we know the name. Then once we have accessed them, LS now shows the files. We are running centos 6.5, we are accessing them via

Hi, I am running an R script from the command line by calling: > R --vanilla < test.R My terminal is part of the Xwin (Xterm) and there is a plot(1:10) command in the test.R script. This will not produce a grahic though. When I start R by calling R then plotting from the R command in the same xterm, I do get a graphic display. How do I create a xwin plot by calling R from the command

Hi, I have an interesting problem. I want to be able to verify that my hostname, ipaddress, and mac address are correct in the DNS/DHCP. I have the values, how do I compare. I am able to use NSLOOKUP for the hostname=ip confirmation How do I do the ip addresss = mac address comparison I tried arp and a few other things. Almost everything on google says either to logon to DHCP (which I do

Hi, I am trying to VGA passthrough Intel HD Graphics 4600 IGD with Xen-unstable 4.4 changeset 27214 and Linux kernel 3.10.0 but was not successful.

This should be simple, but it's not, unless I'm forgetting something. Writing a script, an arg is a filename. So fname=$1 But I want that expanded to include the full path and filename, not just what is given as the arg on the command line. E.g., if the user's cwd is /home/joe/a/b/c/ and he specifies ../x/file-a.ext then the function/utility should transform that into the

Hello, I was reading about secure Dialect negotiation to prevent man-in-middle to downgrade dialects & capabilities. _https://blogs.msdn.microsoft.com/openspecification/2012/06/28/smb3-secure-dialect-negotiation/_ I wanted to ask, is there any option to disable SMB2 to do dialect renegotiation as present in Windows8 clients, as they can control using RequireSecureNegotiate. -- Thanks Amit

Hi, Using R 2.15.1 on Windows 7. Have installed both versions 32 and 64bit. In both of them among others I have installed a package rgenoud When I open R gui of 32bit and write library(rgenoud) it responds by showing a functional rgenoud version 5.7-8. The same it does on Rgui 64bit. Now I am working in cygwin (v. 1.12.4.0) with xwin. Normally before when I had installed a package, I only had

Hola Fernando, yo en mi trabajo tengo un asus i7(pensaba que era i5) con 4 gb de RAM (windows7) en casa tengo uno portatil con 16 gb funcionando con ubuntu marca dell (alienware). Sinceramente, mi experiencia me dice que no hay color de una marca buena a una normal. De hecho el alienware corre más rápido que un sobremesa mac que tenemos en el laboratorio de caracteristica similares. Problema,
