Description of problem:
When you run the program it creates e new /etc/resolv.conf file replacing the old one.
But the new one has owner and group =root and permissions 0077.
It should be 0022. Otherwise, only root can resolv adresses
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Start the program
2.ls -l /etc/resolv.conf
Actual Results: -rw------- 1 root root 25 jun 2 19:19 /etc/resolv.conf
Expected Results: -rw-r--r-- 1 root root 25 jun 2 19:20 /etc/resolv.conf
How are you running pptp? What options are you passing to it?
/etc/resolv.conf is not actually modified by pptp itself but by pppd, so if
anything it's likely that there's a problem there or with an if-up script you're
Ok, it is not a bug in Fedora Extras, I used the pptpconfig-20040722-6 package
from sourceforge to have a graphical frontend. It is this program who actually
changes the /etc/resolv.conf from /var/run/ppp/resolv.conf
If I use the command line
pppd debug updetach logfd 1 linkname MYNET-i dump noauth
refuse-chaprefuse-mschap name MYNET\\myself remotename MYNET-i ipparam MYNET-i
nobsdcomp nodeflate usepeerdns pty "pptp 18.104.22.168 --nolaunchpppd debug dump"
everithing works ok as long as it does not change the /etc/resolv.con
Since I'm also the maintainer of the upstream packages, I still have an interest
in this. Could you please report this issue on the pptpclient-devel mailing list?
I found the origin of the problem. A custom /etc/bashrc that sometimes sets
incorrect masks, I realized when I started to have similar problems with another
program. After replacing it by the default fedora /etc/bashrc everyting works fine
