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

Hi: RHEL 8.3 doesn't offer extended update support, so it seems be EOL this month. but centos8 will be supported until December. so will there be centos 8.4, or centos 8.3 will do the extend update support itself?

yumex for CentOS 8.3
by Robert G. (Doc) Savage 10 May '21

10 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?

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

What is the best (and free) Linux softphone?
by Turritopsis Dohrnii Teo En Ming 05 May '21

05 May '21

Subject: What is the best (and free) Linux softphone? Good day from Singapore, I already have an Asterisk-based FreePBX VoIP IP PBX SIP server virtual appliance (VirtualBox). I do not want to spend so much money on buying physical IP phones. Recently, I migrated my Fortigate 60D firewall, Huawei E3276s-920 4G LTE USB modem, FreePBX virtual appliance (on laptop) and 1 unit of Cisco 7960 IP phone from my home to the community hostel. I cannot migrate too many hardware to the community hostel even though I have 4 Cisco 7960 IP phones. As stated earlier, I do not want to spend so much money on buying physical IP phones. I am trying to save as much money as possible as I live in extreme poverty in Singapore. My proposed solution is to install many Linux virtual machines on my laptop. Each Linux virtual machine will have a softphone. So my ultimate question is: What is the best (and free) Linux softphone available? Do I have many choices? I am looking forward to your reply.
