Re: [CentOS] LARTC and CentOS question

[Robert Stuart]

/usr/share/doc/initscripts-8.45.30/sysconfig.txt covers the syntax of 
sysconfig files.


also browsing through /etc/sysconfig/network-scripts/ifup* scripts will 
give some good info (eg ifup-routes).

Hello all,

Got myself the Linux Advanced Routing & Traffic control book
http://lartc.org/howto/

All the commands in the guide do not survive reboots.

Could someone point me in the right direction, where I can find 
CentOS/Redhat specific documentation on the whole 
/etc/sysconfig/network* setup?



For static routes use /etc/sysconfig/network-scripts/route-ethN. The
format is:

for `ip r a 1.2.3.4 dev ethN.N' the route-ethN would be:
`1.2.3.4 dev ethN.N'.

For routing rules, use /etc/sysconfig/network-scripts/rule-ethN in
simmilar way as above.

Re: [CentOS] yum install to a portable location

[Robert Stuart]

Hi Dan,

Chroot gets you a space that "looks" like it is a separate system. Given 
this is R, I assume you are probably wanting this for HPC like 
purposes... Could I suggest building your own version of R and 
installing into a nfs area? You may also wish to investigate the 
facilities provided by the package environment-modules - they can be 
quite handy (these aren't environmental monitoring).

My R users tend to need the later versions of R. I configure R with 
something like:
./configure --prefix=/nfs_apps --enable-R-shlib --with-x --with-tcltk

Regards
Robert
