lee l...@yagibdah.de writes: Hi, what do you as PDF viewer? Most of the time, I was using xpdf, and that doesn't seem to be available in Gentoo. I compiled it from source and found out that it cannot display PDFs so well and gives error messages about not being able to find fonts. Pdfpc isn't a good alternative. Most of the time I use app-test/zathura, whose default key-binding is vim-style. But recently I found app-test/llpp a better choice, at least the speed of fulltext search is very-very-very fast. But I 'm still wondering if there 's some better one. -- Zesen Qian (钱泽森)
Re: [gentoo-user] Disable IPv6 on specific interface

Unless the kernel knows of the enp4s0 interface and therefore lists it under sysctl, I can't see how it can be disabled. You could try disabling IPv6 altogether in the kernel, but this may not be what you want to achieve. Alternatively, have a look with modinfo in the module options in the unlikely chance that the module has some option which disables IPv6 functionality. Hello Mick, The module ipv6 has only three parameters, each of which is disable ipv6, disable ipv6 on all interfaces, disable autoconf on all interfaces, none of these is what I want to achieve. Module tg3 has only on parameters which control the debug level. Currently I just call sysctl net.ipv6.conf.enp4s0.disable_ipv6=1 in preup(), which works just fine. I 'm just wondering if there 's some more proper way to do it. Since in my opinion, this should be done at the first moment when the interface is present, not when the interface is up. -- Zesen Qian (钱泽森)

Alternatively, have a look with modinfo in the module options in the unlikely chance that the module has some option which disables IPv6 functionality. You may be able to use the feature of modprobe that executes a command when the module loads and that way disable the ipv6 interface. I have not tried this myself. Hello Covici, Yes, there's a rule named install modulename [command..] in modprobe, but aren't they only applied to modprobe itself? I mean, in my case the ipv6 and tg3 is loaded automatically(maybe by udev?), not by running modprobe ipv6. is this kind of module loading also affected by modprobe rule(in /etc/modprobe.d/*.conf)? -- Zesen Qian (钱泽森)

[gentoo-user] [Permission]Cannot emerge [sys-libs/libcap-ng-0.7.4]
Hi list,
I 'm trying to emerge net-analyzer/tcpdump-4.6.2, to debug some ICMPv6
problem I recently encountered. So, I type:
Riaqn-Laptop ~ # emerge -av tcpdump
These are the packages that would be merged, in order:

However, the permission looks quite right, I(root) can even write to it:
Riaqn-Laptop ~ # ls -l /proc/sys/net/ipv6/conf/enp4s0/autoconf
-rw-r--r-- 1 root root 0 12月 9 22:58 /proc/sys/net/ipv6/conf/enp4s0/autoconf
Even if I emerge with FEATURES=-userpriv doesn't help, same output.
I don't know if it's related, but as far as I noticed, dhcpcd will set
these two values to 0, to disable the kernel configuring the IPv6
address.(I checked dhcpcd source)
Any comment is appreciated!
