_ xchatが

最近

yab@hrestol:~/plum$ The program 'xchat' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 15744916 error_code 1 request_code 0 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

といってたまに落ちるのでloquiを試してみる．

_ [Debian] rpc.rquotad

というのがある /etc/init.d/quotarpc から起動できる．設定前なので，こんな感じ

OOo-build:/usr/share/doc/quota# /etc/init.d/quotarpc start
+ PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
+ NAME=rpc.rquotad
+ DESC=quota service
+ DAEMON=/usr/sbin/rpc.rquotad
+ test -f /etc/exports
+ grep -q '^[^#]*quota' /etc/fstab
+ need_rquotad=0
+ test -f /usr/sbin/rpc.rquotad
+ test -f /etc/default/quota
+ . /etc/default/quota
++ run_warnquota=true
+ set -e
+ '[' -x /usr/sbin/rpc.rquotad ']'
+ '[' 0 = 1 ']'
+ exit 0

テスト機はこんな構成 cfdiskの出力なので単位はMBです．

 hda1 Primary Linux ext2       131.61         
 hda3 Primary Linux ext2      5996.23         
 hda4 Primary Linux ext2     53382.07         
 hda5 Logical Linux swap       509.97         

vi /etc/fstab

/dev/hda4       /home   ext2    defaults                        0       2

/dev/hda4       /home   ext2    defaults,usrquota,grpquota      0       2

上記の行を下記の行に変更した．で次のステップ

OOo-build:~# cd /home/
OOo-build:/home# ls
ikuya  lost+found  shutta  yabuki
OOo-build:/home# touch quota.user quota.group
OOo-build:/home# ls -la

OOo-build:/home# quotacheck -avug
quotacheck: Can't find filesystem to check or filesystem not mounted with quota option.
OOo-build:/home# sync
OOo-build:/home# 

マウントをやりなおして，quotacheck -avug を実行．チェックが終了するのにコーヒーを飲む時間ぐらいかかった．

OOo-build:/home# sync
OOo-build:/home# mount /home/
mount: /dev/hda4 already mounted or /home busy
mount: according to mtab, /dev/hda4 is already mounted on /home
OOo-build:/home# mount -o remount  /home/
OOo-build:/home# quotacheck -avug

quotacheck: Scanning /dev/hda4 [/home] done

OOo-build:/home# 

ということで，quotarpcデーモンを動かしてみる

OOo-build:/home# /etc/init.d/quotarpc start
+ PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
+ NAME=rpc.rquotad
+ DESC=quota service
+ DAEMON=/usr/sbin/rpc.rquotad
+ test -f /etc/exports
+ grep -q '^[^#]*quota' /etc/fstab
+ grep -q '^/' /etc/exports
+ need_rquotad=1
+ test -f /usr/sbin/rpc.rquotad
+ test -f /etc/default/quota
+ . /etc/default/quota
++ run_warnquota=true
+ set -e
+ '[' -x /usr/sbin/rpc.rquotad ']'
+ '[' 1 = 1 ']'
+ echo -n 'Starting quota service: '
Starting quota service: + start-stop-daemon --start --quiet --exec /usr/sbin/rpc.rquotad --
+ echo rpc.rquotad.
rpc.rquotad.
+ exit 0
OOo-build:/home# 

クライアントの方からも，反応が返るようになりました．設定前

yab@hrestol:~$ quota
quota: : error while getting quota from ooo-build.exsample.com:/home/ikuya for 1000: 接続を拒否されました

設定後

yab@hrestol:~$ quota
Disk quotas for user yab (uid 1000): none
yab@hrestol:~$ 

ここで，チョットだけ確認：わたしのhrestolでのuidは，

yab@hrestol:~$ id
uid=1000(yab) gid=1000(yab) 所属グループ=1000(yab),0(root),4(adm),6(disk),24(cdrom),25(floppy),29(audio),40(src),50(staff),100(users),109(uml-net)

です．これに対応するooo-buildでのuid=1000は，/etc/passwdで確認した所，yabukiでした．

yabuki@OOo-build:~$ id
uid=1000(yabuki) gid=1000(yabuki) groups=1000(yabuki)

だったが，テストの都合上 /etc/groupsを見て，vipwを実行してgroupをstaff(50)へ変更した．

edquota -u yabuki

ooo-build側は

  Filesystem                   blocks       soft       hard     inodes     soft     hard

としてみた．(わざと，超過させてみた)

次は直したもの

Userの次の -+が--になったり，graceにカウントダウンがなくなったりと気が付かれた人も多いと思う．

_ quota -t

default が，7days なので，極端な値として, quota -ug -t で1secondsを設定

_ 大切なことを忘れていた．

/etc/init.d/quota start

_ 21:15
