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 to
no by default. Server is currently offline, so I won't post entire config, but this is from "regular", physical WAN facing interface
eth0). When i configured another physical NIC using
nmtui, 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.
- 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)
manpages reveal that information
/usr/share/doc/initscripts-*/sysconfig.txtdescribes most of the options that go into
ifcfg-*files for different types of connection, however there's no mention of
- briefly browsed through http://linux-ip.net/ that contains IP Command reference
ip-cref.ps, to which
man ifcfgrefers 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
yesyet, 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.
