Yast2 Proxy Issue

English Network/Internet

Hi.

This is a follow up question to my squid proxy server thread at https://forums.opensuse.org/showthread.php/564820-Squid-not-working-as-expected .

I use the Yast2 Proxy tool on a client PC to use the new squid proxy server I set up on another PC. The TEST featured tests ok.

chris@asus-roc:~> sudo yast2 proxy summary


* Proxy is enabled.
* HTTP Proxy: http://10.1.1.33:3128
* HTTPS Proxy: http://10.1.1.33:3128
* FTP Proxy: http://10.1.1.33:3128

This updates the /etc/sysconfig/proxy file -

I then log out then in.

This, as I understand it, sets the proxy server settings system wide on the client. However, I am not seeing that. If I use ftp in a terminal or just plain web browse with firefox, the iftop network monitor tool shows me that ftp, firefox etc are not using the proxy on 10.1.1.33.

If I set the proxy manually in firefox’s settings then that traffic is through the proxy.

It seems to me that that “Yast2 Proxy” does nothing. Am I setting up a system wide proxy correctly? Do I need to add something to my NetworkManager settings?

For what it’s worth, there are no proxy related environment variables created either.
Help.

Thanks.

Please ignore my previous quote on environment variables. The do get created.

hris@asus-roc:~> env |grep -i PROXY
no_proxy=localhost,127.0.0.1
gopher_proxy=
ftp_proxy=http://10.1.1.33:3128
https_proxy=http://10.1.1.33:3128
socks_proxy=
NO_PROXY=localhost,127.0.0.1
http_proxy=http://10.1.1.33:3128
SOCKS_PROXY=

No, it only sets proxy for root user for using administrative tools. It does not change settings for others, non-root, users.

Thanks. So how do I set the proxy for non-root users - hopefully not on a per application basis?

I hate to sort of contradict you, but the creation of the 3 proxy environment variables from “yast proxy” are automatically used by apps like wget, curl, mpv etc in my testing.

Still having issues with ftp but I shall persist.

OK, thank you. I may have misremembered this.
