Hi Sudo has me boggled ..... I'm trying to configure a group %linuxadmins .. My account is a member of linuxadmins , when I sudo iptables -h I get "sudo: iptables: command not found". If I sudo /sbin/iptables -h it works fine. My config is at follows (standard config) Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig, /bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/mii-tool Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig Cmnd_Alias LOCATE = /usr/bin/updatedb Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/parted, /sbin/partprobe, /bin/mount, /bin/umount Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown, /bin/chmod, /bin/chgrp Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall Cmnd_Alias DRIVERS = /sbin/modprobe Defaults requiretty Defaults env_reset Defaults env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR \ LS_COLORS MAIL PS1 PS2 QTDIR USERNAME \ LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION \ LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC \ LC_PAPER LC_TELEPHONE LC_TIME LC_ALL LANGUAGE LINGUAS \ _XKB_CHARSET XAUTHORITY" %linuxadmins ALL=(ALL) ALL I have also tried %linuxadmins ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS with the same results.
