[blocks B ] sys-apps/pam-login (is blocking sys-apps/shadow-4.0.18.1)

and

[blocks B ] <net-misc/dhcpcd-2.0.0 (is blocking sys-apps/baselayout-1.12.6)

I have already killed my linode trying to reslove these blocks can someone help me resolve these safely?

I tried emerging dhcpd and that killed my linode.
I also tried removing dhcpd and pam-login and that also killed my linode. Im not sure I guess the dhcpd is used to obtain the address from linode but im not sure exactly.

I have started a clean gentoo install and when I emerge -DavuN world I get these blocks but I am not sure how to get around them without making my linode useless.

I found this but havent done it yet

Is this safe to do on a linode

"emerge -C pam-login && emerge -1 shadow"

or is this a better solution also from the same post

"emerge --buildpkgonly --nodeps shadow && emerge -C pam-login && emerge --usepkgonly shadow"

found in the following post
http://forums.gentoo.org/viewtopic-p-3178419.html#3178419


Im not sure what the difference would be can someone explain?
this still wouldnt resolve the dhcpdcp block though

[fifo]

So I decided to give it a shot after reading up a bit!!!

emerge -C pam-login && emerge -1 shadow

it worked like a charm just remember to etc-update

Also restart sshd
/etc/init.d/sshd restart

now on to the dhcpcd problem

[fifo]

so I felt gutsy and tried the same with the other block and well of course it didn't work below is my output.

Your emerge got rid of dhcpd (and the dhcp client), so broke your Gentoo/Linode.

A workaround -- until you manage to get dhcpd installed again -- is to add your Linode's IP/gateway addresses to the net.eth0 config file.

Your Linode IP/Gateway addresses are given at: https://www.linode.com/members/netinfo.cfm

For info on how to configure net devices under Gentoo, see:
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=1

You'll need the following in the file /etc/init.d/net.eth0:
Code: config_eth0=( "<your Linode IP address>/32" )
routes_eth0=( "default via <Gateway address>" )

Then reboot your Linode.

Cliff,

Thanks for the reply. I am currently setting up my linode again but havent gotten to this step just yet. Is it wise to do that emerge the way I did? Should I just reemerge dhcpcd when the emerge -C dhcpcd && emerge -1 shadow is done and do my etc-update?

[c1i77]

Hi,

If your Linode has no configured network device (implied by the eth0 snippet you posted), you'll need to do the net.eth0 part first. And then run /etc/init.d/net.eth0 start (I guess).

Code:
[blocks B ] <net-misc/dhcpcd-2.0.0 (is blocking sys-apps/baselayout-1.12.6)


When you have network access again, emerge -uv dhcpcd. The latest package seems to be compatible with baselayout so you shouldn't have any trouble installing it ( http://packages.gentoo.org/search/?sstring=dhcpcd ).

Code:
[blocks B ] sys-apps/pam-login (is blocking sys-apps/shadow-4.0.18.1)


It looks as if pam-login has been deprecated -- it is no longer in portage: http://packages.gentoo.org/search/?sstring=pam-login

Code:
emerge -C pam-login && emerge -1 shadow


I guess 'shadow' will replace the functionality of pam-login and therefore, as others have suggested it is safe to do the above.

Good luck,

Cliff

Awesome that clears things up. Really appreciate your help. I will let you know how it goes!!! Thanks again!

[fifo]

Ok so heres what I did...

# emerge -c dhcpcd && emerge -1 shadow
# etc-update
# emerge -dhcpcd
# etc-update
# rm /etc/init.d/net.etho
# cd /etc/init.d
# ln -s net.lo net.eth0

This is what killed me that was not correct because I was using the old configuration style
edit /etc/conf.d/net
uncomment the following line
config_eth0=( "dhcp" )

/etc/init.d/net.eth0 restart

rc-update add net.eth0 default

and bam it worked!!!!

Thanks for all your help. Really appreciate it!!!
