Re: vnc not reachable

I found out why vnc wouldn't load at port 5901, there were lock files in /tmp. I removed them, rebooted the server and now it's working. I still don't know how / why VNC was loading at port 5906. The version of vncserver with CentOS 7 will use the next higher number if the one requested is in use. ...

Re: How to view mapped drives

If you are you trying to see what the server has exported.

For NFS

# exports

For samba

# smbstatus

Connecting with more than one stream.

Is there a way to get the iwlwifi module to connect with multiple streams? The controller supposed to support dual streams and I am working with Cisco 3702 APs that will definitely support it. 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24) Subsystem: Intel Corporatio...

Re: CentOS Virtualization

I no longer have any CentOS hosted VMs but when I did I used virsh to manage them. Start with the list command to see what machines are on your host.

Re: Upgrade to 6.10 breaks icedtea. (Solved)

Thanks.

It just will not run with Firefox 60 ESR on any platform I tested but I finally got it working using Chrome on Windows.

I remember back about 1995 I thought Java was a good idea. I was wrong. It has morphed into "write once; debug everywhere."

I am marking this "solved".

Re: Upgrade to 6.10 breaks icedtea.

Are you sure? It is my understanding that Firefox 60 ESR dropped all support for running Java in the browser. That would make icedtea or some similar program pretty important if I need to run a Java applet.

Upgrade to 6.10 breaks icedtea.

I recently updated several CentOS 6 machines to 6.10. Something in that upgrade seems to have broken iced-tea. It stops with following error message: Exception in thread "main" java.lang.UnsupportedClassVersionError: net/sourceforge/jnlp/runtime/Boot : Unsupported major.minor version 52.0 at java.la...

Re: Mapping NFS uid/gid to different numbers

I finally figured it out. The default is for NFS to send numeric ids. so # echo "options nfsd nfs4_disable_idmapping=0" >/etc/modprobe.d/nfsd.conf # service nfs restart This causes NFS to send user and group as text instead of numbers. ie: user@domain.com and group@domain.com Add to /etc/idmapd.conf...

[Solved] Mapping NFS uid/gid to different numbers

I have some legacy Solaris systems that use different UIDs than my linux boxes. There are NFS exports on a CentOS 6 system that use the Solaris UID/GID for the exported files. These files must now be exported to the Linux servers. Solaris servers: uid=51(oracle) gid=50(dba) Linux servers: uid=270(or...
