Xem cấu hình máy trên linux

Trên linux để xem thông tin cấu hình đầy đủ về hardware của máy ta cài thêm phần phềm List Hardware, giống như xài cpu-z hay everest bên window, ta vào trang này để down về

http://dag.wieers.com/rpm/packages/lshw/

Centos thì nên dùng phiên bản bên dưới.

wget https://ftp.tu-chemnitz.de/pub/linux/dag/redhat/el6/en/x86_64/rpmforge/RPMS/lshw-2.15-1.el6.rf.x86_64.rpm

Download xong ta tien hanh cai dat

rpm -ivh lshw-2.15-1.el6.rf.x86_64.rpm

sau khi cài xong ta gõ lshw sẽ được thông tin chính xác và đầy đủ về hardware cũng nhưng firmware bios , xài ram gì, còn bao nhiu khe ram trống, hdd, cpu hiệu gì ....

Cái này mình cài rồi và đã chạy ok, nhưng bẵng đi 1 thời gian khi quay lại gõ lệnh lshw thì nó báo lỗi "Segment failed"

Có ai biết cách fix ko ?

[emailhoc]

Cái này dễ lắm bạn. Bạn chỉ cần vào link http://rpmforge.sw.be/redhat/el5/en/i386/rpmforge/RPMS/ và tải về gói lshw phiên bản mới nhất sau đó gõ lệnh để nâng cấp là xong

rpm -U lshw.<version>.rpm
