I am trying to set up proxies on my Red Hat Enterprise Linux 9. I am trying to install CNTLM proxy authentication software. I downloaded the RPM file from the official repo and tried the following command: sudo rpm -Uvh cntlm-0.92.3-1.x86_64.rpm However, I get error: Failed dependencies: /sbin/chkconfig is needed by cntlm-0.92.3-1.x86_64 To try to fix this, I used the following command: sudo dnf install chkconfig This had the following output: Updating Subscription Management repositories.

Failed: chkconfig-1.20-2.el9.x86_64 First off, the "error unpacking rpm..." error message and the "Installed products updated" messages seem contradictory; I don't understand exactly what's going on there. Secondly, this appears to make no difference - I'm still unable to do the cntlm install. Can anyone suggest how I can fix this so that I can install cntlm?

The service is running: » sudo service cntlm status ● cntlm.service - LSB: Authenticating HTTP accelerator for NTLM secured proxies Loaded: loaded (/etc/init.d/cntlm; bad; vendor preset: enabled) Active: active (exited) since Tue 2018-02-20 12:01:02 CET; 3min 33s ago Docs: man:systemd-sysv-generator(8) Process: 9215 ExecStop=/etc/init.d/cntlm stop (code=exited, status=0/SUCCESS) Process: 9298 ExecStart=/etc/init.d/cntlm start (code=exited, status=0/SUCCESS) Tasks: 0 Memory: 0B CPU: 0 Feb 20 12:01:02 host1 systemd: Starting LSB: Authenticating HTTP accelerator for NTLM secured proxies...

But there is no process: » ps -ef | grep cntlm dangonfast 12466 13067 0 12:05 pts/19 00:00:00 grep --color=auto cntlm Why is that?

My work uses an NTLM proxy. On my Linux servers and workstations we us cntlm to authenticate. I'm not having any issues with yum,wget, or the web browser, but for some reason curl refuses to work correctly.
