한글 나오게 하기
.bashrc에 export LANG=ko_KR.UTF-8
X에 한글글꼴이 없을 수 있음. 그러면 윈도우에 글꼴 몇개 가져다가/usr/share/fonts/ms/에 넣고
# cd /usr/share/fonts/ms
# mkfontscale
# ttmkfdir
# fc-cache
# chmod -R a+r /usr/share/fonts/msfont
이렇게 하면 됨. 글꼴파일 이름이 한글이어도 정상동작했고 firefox에서 자동으로 인식했음. 터미널에는 글꼴 없어도 export LANG만 가지고도 됨.여기참고했음. 나는 fonts.dir, fonts.cache-1같은것이 생기지 않았기 때문에 저 중에 무언가를 빼도 될것같기도 함.
gcc설치
yum groupinstall 'Development Tools'
selinux
- see /etc/sysconfig/iptables (if you cannot access port 80 at remote place)
- Modify that file or
- Use the
system-config-firewallcommand - if this is not a problem, see this CentOS wiki page
semanage port -a -t http_port_t -p tcp 81
- Use
setenforcecommand instead ofecho 0 > /selinux/enforce(Because just simple. no other reasons) ls -Zps -ZC httpd- or
ps -eZ
- or
unix time conversion
# date -d @1187769064
Base64 decode to file

gateway ip
$ route -n $ netstat -r -n $ ip route show
gateway가 아예 안나올 때(via ~가 보이지 않는다거나 route에서 gateway가 *.*.*.*)가 있던데 이건 어떤 경우인지 모르겠다.
