Segmentation fault

To start xampp, I typed

sudo /opt/lampp/lampp start

Please help, How can I solve this?

Thanks.

The permissions of this file do not change by itself. If you have not changed the permissions yourself, you could have executed a malicious script as root and have more worries. – Lekensteyn Mar 8 '11 at 12:56

Please check the following :

1.sudo gedit /etc/hosts
2.if ip address and hostname not there please write them and save the file.

Please feed us back if you still facing same problem !

and you can change permission by: sudo chmod 0440 /etc/sudoers – moata_u Mar 8 '11 at 12:35

that will not work. You cannot fix sudo with sudo. The user needs to boot in recovery mode in order to set the right permissions. – Lekensteyn Mar 8 '11 at 12:54
    
@Lekensteyn , you write user need boot from live cd and mount the partition that include file system and changed the partition ...sorry :) – moata_u Mar 8 '11 at 13:11

No, I meant the user should hold SHIFT to get the GRUB2 menu and choose "Recovery mode" instead of the usual boot entry. From there, choose "Root prompt" and run chmod 440 /etc/sudoers. (note that 0440 and 440 are the same thing) – Lekensteyn Mar 8 '11 at 13:29
