What is BROWSER_ONLY option in ifcfg-* network configuration files?
I found NetworkManager docs that suggests this setting is only used if you also configure proxy settings, i.e. you have PROXY_METHOD=auto
present, and then determines whether the proxy settings are for everything of just browsers, however they think they can distinguish that. The default is no
already.

In my RHEL 7 minimal installation with Virtualization profile I found that interfaces configured with network manager(s) contain
BROWSER_ONLY=no
option, which is always set tono
by default. Server is currently offline, so I won't post entire config, but this is from "regular", physical WAN facing interfaceenp5s0
(eth0
). When i configured another physical NIC usingnmtui
, the same option appeared. I've seen it in many config files posted online.Now, if I don't know it, then probably I don't need it. Of course that's not the case, this is purely out of curiosity. Does the name literally mean "this interface is only for web browser-related traffic"? I can see how that would make sense with dedicated physical card, possibly VPN/IPSEC, meant only for safe browsing, maybe online banking, stock exchange(sic.), finance.
Research:
- all duckduckgo searches return content of ifcfg-* files that contain this option by default set to "no". I've tried searching for a phrase "BROWSER_ONLY=yes" to no avail
- neither of IFCFG(8), IP(8), NETWORKS(5)
man
pages reveal that information -
/usr/share/doc/initscripts-*/sysconfig.txt
describes most of the options that go intoifcfg-*
files for different types of connection, however there's no mention ofBROWSER_ONLY
- briefly browsed through http://linux-ip.net/ that contains IP Command reference
ip-cref.ps
, to whichman ifcfg
refers and which I didn't find on my system - and of course here, on Stack Exchange
-
grep -R BROWSER /usr/share/doc/*
,info --apropos=BROWSER_ONLY
- guess what... - haven't tried changing it to
yes
yet, however I doubt to see any difference, unless the interface will stop working altogether
Does it mean absolutely no one is using it? Is it some hidden or reserved for future use option?
I'm torn between posting this question in Unix&Linux and Server Fault. Not sure where it fits better.

yahol about 6 yearsThat makes sense. Thank you for providing that link, I see it explains all(?) the variables that go into
network-scripts
files; very useful resource. Now I'll sleep better...
