systemd and 'Stale file handle' errors?
by James Pearson 14 May '21

14 May '21

I have a CentOS 7 system where I needed to restart chronyd - but the systemctl restart failed with the error: systemd[1]: Starting NTP client/server... systemd[43578]: Failed at step NAMESPACE spawning /usr/sbin/chronyd: Stale file handle systemd[1]: chronyd.service: control process exited, code=exited status=226 Turns out there are a couple of Stale NFS file handles from fuse mounts (related to gvfsd) of sub directories under an NFS mounted home directory server - but the home directory for the user in this case, no longer exist (user has left) However, I have no idea why these 'Stale file handles' prevent a service being started by systemd ? In this case, chronyd has nothing to do with NFS mounted user home directories - so shouldn't really care ? I have tried everything I can think of to clear these stale mounts, but with no luck Does anyone know why systemd complains about unconnected 'Stale file handles' - and is there any way I can tell systemctl to start a service regardless of these 'errors' ? Rebooting the host will be a last resort (the system is used by many users) - but in the meantime, I've manually started the /usr/sbin/chronyd binary directly, which runs fine Thanks James Pearson

cups, stalling the transfer of printed files from the local machines to the cups print server
by Gregory P. Ennis 12 May '21

12 May '21

Everyone, I have been having some problems with our cups printing service for the last 4 months. I have a gateway machine that holds the printer information and is the print server. The other machines on the network use cups and cups-browsed that are set up to spool the print jobs to the gateway and then the gateway sends the data stream to the respective printers. The problem I have is that on any of the local machines the print jobs stall. I can run lpstat lpt6 for instance which gives me the listing of the stalled print jobs, but I am not seeing error messages in the logs either on the local machine or on the gateway print server. In doing some google searching I found that there was a problem with gh ghostscript-9.07-31.el7_6.10.x86_64 and ghostscript-cups-9.07- 31.el7_6.10.x86_64 that was apparently fixed. I am running Centos 7.9 that is fully updated with gs 9.25 on both the local machines and the gateway. The problem is intermittent and appears with various file types pdf, ps, pcl, and txt. I have not been able to identify any specific or consistent association. If any of you have had this problem I would sure appreciate your help. Thanks in advance !!!! -- Greg Ennis

ipforwarding -- routing
by R C 11 May '21

11 May '21

Hello, I have an accesspoint, that I connected to one ethernetport, the ap has ip 192.168.67.6, the port 192.168.67.1 I want to forward/route traffic for anything in 192.168.66.0 to go to that access point, and from the ap to the other port. What is the best way to do that? I tried: sudo sysctl -w net.ipv4.ip_forward=1 sudo firewall-cmd --direct --add-rule ipv4 filter FORWARD 0 -o eno1 -i enp0s20u4u1 -j ACCEPT sudo firewall-cmd --direct --add-rule ipv4 filter FORWARD 0 -o enp0s20u4u1 -i eno1 -j ACCEPT but that doesn't seem to work. thanks, Ron

yumex for CentOS 8.3

09 May '21

If yumex is no longer available, please advise. A few minutes ago when 'dnfdragora' failed for CentOS 8.3, I tried: # yumex --root bash: yumex: command not found... Install package 'yumex' to provide command 'yumex'? [N/y] y * Waiting in queue... * Loading list of packages.... Failed to install packages: Could not depsolve transaction; 1 problem detected: Problem: conflicting requests - nothing provides python-iniparse needed by yumex-3.0.15-1.el7.nux.noarch - nothing provides pycairo needed by yumex-3.0.15-1.el7.nux.noarch - nothing provides dbus-python needed by yumex-3.0.15-1.el7.nux.noarch - nothing provides /usr/bin/python needed by yumex-3.0.15-1.el7.nux.noarch - nothing provides pexpect needed by yumex-3.0.15-1.el7.nux.noarch - nothing provides python-kitchen needed by yumex-3.0.15-1.el7.nux.noarch - nothing provides urlgrabber needed by yumex-3.0.15-1.el7.nux.noarch Is this a long-winded way of telling me to forget it?

EPEL appears to have libfluidsynth.so.1 for centos-7 fluidsynth-libs-1.1.6-7.el7.x86_64 Repo : epel Matched from: Filename : /usr/lib64/libfluidsynth.so.1 Filename : /usr/lib64/libfluidsynth.so.1.5.2 Did you cut something out from the message? I wouldn't expect (only) a "nothing provides" message under "Problem: conflicting requests:"

NetworkManager: Remove one of two DHCP leases
by Kenneth Porter 07 May '21

07 May '21

I forgot to release the DHCP IPv4 lease on a PC before I deployed it at the customer site. So now the box has two leases for a couple days, when the old lease expires. What's the proper way to force the unwanted additional lease to expire immediately? It's mucking up my resolv.conf with the old DNS search order and servers added to the customer's. I checked the /var/lib/NetworkManager/dhclient6-*.lease file and see my own IPv6 configuration and nothing from the customer, which explains why I can't connect to resolved IPv6 addresses. How can I flush that? (There are two identical lease6 records but both are to my home LAN. Why are there two copies?)

CentOS are Debian / Ubuntu mirror
by Rudi Ahlers 06 May '21

06 May '21

Hi, Does anyone have some instructions on setting up a CentOS server as mirror for Debian and Ubuntu distributions? I already setup a YUM mirror and this works fairly well, but cannot seem to figure out how to mirror Debian and Ubuntu repositories. -- Kind Regards Rudi Ahlers Website: http://www.rudiahlers.co.za
