I built my CentOS 7 server with a raid 1 mirror. I found the raid setup in the installer to be confusing and very non-intuitive. I don't remember having any problems with it in previous versions. -- Bowie

patching bash 2.05b for Shellshock
by Boris Epstein 08 Oct '14

08 Oct '14

Hello all, Amongst a number of modern CentOS machines we have this one RHEL 3 machine (don't ask me why:) and on it we have bash 2.05b. I was trying to compile a version of bash for it that would be Shellshock-proofed. To do that, I downloaded a copy of the code from the GNU along with all the 13 patches, applied the patches, compiled the code and installed the executable. All vulnerabilities appear to be fixed with the exception of CVE-2014-7187. Does anybody know why this may be? Thanks. Boris.

centos 7, docker, NFS and uid = -2
by Mauricio Tavares 08 Oct '14

08 Oct '14

I created a centos 7 docker container in which I want to mount a NFS share in. Said share is owned by user virtual with uid 1200. So I do some exporting (docker container is in 172.17.0.0/16): spindizzy> cat /etc/exports /export 10.0.0.0/24(ro,fsid=0,no_subtree_check,sync) 172.17.0.0/16(ro,fsid=0,no_subtree_check,sync) [...] /export/mail 172.17.0.0/16(rw,root_squash,no_subtree_check,sync) spindizzy> and then some mounting: bash-4.2# id virtual uid=1200(virtual) gid=1200(virtual) groups=1200(virtual) bash-4.2# nfsstat -m bash-4.2# mount.nfs4 -v -o proto=tcp fileserver.in.kushana.com:mail /var/spool/vmail mount.nfs4: timeout set for Wed Oct 8 03:11:43 2014 mount.nfs4: trying text-based options 'proto=tcp,addr=10.0.0.18,clientaddr=172.17.0.29' bash-4.2# nfsstat -m /var/spool/vmail from fileserver.in.kushana.com://mail Flags: rw,relatime,vers=4.0,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=172.17.0.29,local_lock=none,addr=10.0.0.18 bash-4.2# ls -l /var/spool/ total 12 drwxr-xr-x 2 root root 4096 Jun 10 01:11 lpd drwxrwxr-x 2 root mail 4096 Oct 8 02:15 mail drwxr-xr-x 2 4294967294 4294967294 4096 Oct 3 17:34 vmail bash-4.2# And am getting the famous share being mounted as nobody issue. In the client (docker container), I went in /etc/idmapd.conf and set the Domain to be the domain where the NFS server is at (in.kushana.com). Now, how do I restart idmapd? It is a systemd service (/usr/lib/systemd/system/rpcidmapd.service, which uses /etc/sysconfig/nfs).

VNCServer Startup Config
by Igal ＠ getRailo.org 08 Oct '14

08 Oct '14

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 ~/.vnc/xstartup #!/bin/sh [ -r /etc/sysconfig/i18n ] && . /etc/sysconfig/i18n export LANG export SYSFONT vncconfig -iconic & unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS OS=`uname -s` if [ $OS = 'Linux' ]; then case "$WINDOWMANAGER" in *gnome*) if [ -e /etc/SuSE-release ]; then PATH=$PATH:/opt/gnome/bin export PATH fi ;; esac fi if [ -x /etc/X11/xinit/xinitrc ]; then exec /etc/X11/xinit/xinitrc fi if [ -f /etc/X11/xinit/xinitrc ]; then exec sh /etc/X11/xinit/xinitrc fi [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & twm & any thoughts?

umount problem
by Fred Smith 08 Oct '14

08 Oct '14

I've got a usb HD mounted, and it has been mounted since the weekend, and has been kept busy during that period. now I"m done with it an want to umount it, but neither umount nor the on-screen icon (when right-clicked) will let me do it: it is /dev/sdd1, mounted as /media/seagateusb. when root tries to umount it we get this: # umount /media/seagateusb umount: /media/seagateusb: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) lsof | grep sdd1 gives this: $ lsof | grep sdd1 jbd2/sdd1 26358 root cwd DIR 253,1 4096 2 / jbd2/sdd1 26358 root rtd DIR 253,1 4096 2 / jbd2/sdd1 26358 root txt unknown /proc/26358/exe lsof | grep /media/seagateusb yields no output. I know, I could reboot, but I'd just as soon not. Anybody know what that jbd2/sdd1 stuff is that lsof shows me, or how to umount it other than a reboot? thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- Show me your ways, O LORD, teach me your paths; Guide me in your truth and teach me, for you are God my Savior, And my hope is in you all day long. -------------------------- Psalm 25:4-5 (NIV) --------------------------------

And, if you're not worried about connecting from random locations, but only from inside your internal network, you can block outside remote access. dd-wrt's "documentation"? It's as accurate as any other documentation that's been desultorily, in someone's spare time, updated over the last 10 years, and old and obsolete info not deleted.... mark "take your cmts re emacs to alt.religion.editors"

OT - httpd/conf.d include questions - allowing only some addresses
by Robert Moskowitz 07 Oct '14

07 Oct '14

My web searching is not finding out the answers to this, so I turn to you all here. I am trying to NOT modify my httpd/conf/httpd.conf file, and only make changes via includes. I have done that with a 00-init.conf where I set things like servername and serveradmin. Now I want to move my allow and denies to a 01-allow.conf include. I tried: <Directory "/var/www/html"> Order allow,deny deny from all </Directory> as that seems to be what is in the default conf, but I see in the error_log: [Tue Oct 07 08:51:58 2014] [error] [client 208.83.67.156] Directory index forbidden by Options directive: /var/www/html/ And maybe this is not the right restriction, because when I make this change directly in the default httpd.conf, I still can get to the default web page. Now on to the 'allow' statement. All syntax examples I have seen for it follow: allow from 1.1.1.0/24 1.1.2.0/24 2400:cb00:2048:1::/64 and soforth. That is each range separated by a space. But potentially I have 18 ranges to specify, and at least named makes it easy with each range on its own line ending with a ';'. For now I am only putting 2 ranges in, but how does one set up a longer list of allowed ranges? thanks
