Fedora

Gestore Pacchetti Software RPM

• Come avere la lista degli rpm installati ordinati per dimensione?

rpm -qa --qf "%-10{SIZE} %-30{NAME}\n" | sort -n

• sapere a che rpm appartiene un pacchetto:

rpm -q --whatprovides libltdl.so.3
libtool-libs-1.4.3-6

Yum (old)

• gestore repositori Fedora/RedHat

Repositories

• Livna:

rpm -ivh http://rpm.livna.org/livna-release-6.rpm

• Remi:

wget http://remi.collet.free.fr/rpms/fc6.i386/remi-release-1-2.fc6.remi.noarch.rpm
rpm -ivh remi-release-1-2.fc6.remi.noarch.rpm
wget  http://remi.collet.free.fr/RPM-GPG-KEY-remi
rpm --import RPM-GPG-KEY-remi

• ATrpms

echo '[atrpms]
name=Fedora Core $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/fc$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1' > /etc/yum.repos.d/atrpms.repo

rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms

• block a package globally: /etc/yum.conf

exclude=firefox

• block a package from in a repository: /etc/yum.repos.d/repository_name.repo

exclude=package_name

example

• in scientific linux 6.1 , with rpmforge,epel,adobe I have a problem upgrading the syst em after installing VLC:

[root@clustergang01 ~]# yum update
Loaded plugins: refresh-packagekit
epel/metalink                                                                                                                          |  16 kB     00:00

• so I "ban"

exclude=libupnp,libmodplug

from

/etc/yum.repos.d/epel.repo

Installare il Kernel "Futuro"

yum --enablerepo=development update kernel

Cleanup Packages

Find unused config files + Merge and resolve the changes found by the following script: dnf install rpmconf; rpmconf -a. Now find and remove old config which nobody owns: rpmconf -c. 

unused" packages + You can find packages not required by other packages with the tool package-cleanup from the yum-utils package: dnf install yum-utils; package-cleanup --leaves

dnf install rpmreaper

lost" packages + You can find orphaned packages (i.e. packages not in the repositories anymore) with package-cleanup --orphans. This will also show packages which have been partially uninstalled but where the "%postun" script failed

Major Version Update

dnf install fedora-upgrade
fedora-upgrade

multi-user.target

systemctl isolate multi-user.target

networking

• add a static route to the network scripts:

in /etc/sysconfig/network-scripts/route-eth1

192.168.251.0/24        dev eth1 via 192.168.252.1

is the equivalent of doing:

route add -net 192.168.251.0/24 gw 192.168.252.1

BUGS & Problems

USB storage devices

• Usb storage devices (Hard disks, pen drives, cd/dvd) are not working

se facendo:

modprobe usb_storage 

oppure

[root@localhost ~]# dmesg |grep usb_storage|tail -3
usb_storage: Unknown symbol scsi_scan_host
usb_storage: Unknown symbol scsi_add_host
usb_storage: Unknown symbol scsi_host_alloc

si hanno questi errori, una soluzione che ho trovato su un portatile Acer Centrino è:

vi /etc/modprobe.d/scsi_mod

e commento la linea

# options scsi_mod max_scsi_luns=6

provo e inserisco il modulo in memoria:

modprobe usb_storage 
[root@localhost ~]# modinfo usb_storage
