切換到無線時未安裝 Samba 安裝

  • September 7, 2018

我有一個裝有 Scientific Linux 6.1 的筆記本。我有一個帶有 OpenWrt 10.03 - Wrt160NL 的無線路由器。我在通過 samba 共享的路由器上有一個 HDD:

cat /etc/samba/smb.conf.template
[global]
workgroup = workgroup
guest account = nobody
security = share
browseable = yes
guest ok = yes
guest only = no
log level = 2
log file = /tmp/log/smbd.log
max log size = 100
encrypt passwords = yes
dns proxy = no
host allow = 192.168.1.0/24
netbios name = Router
server string = Linksys WRT160NL Router
socket options = TCP_NODELAY
client code page = 852
dos charset = 852
unix charset = UTF-8
display charset = UTF-8
character set = ISO8859-2

[SHARE]
comment = SHARE
path = /mnt/hdd/PUB
browseable = yes
public = yes
guest ok = yes
writable = no

在客戶端:

cat /etc/fstab
//192.168.1.1/SHARE /home/USERNAME/Desktop/SHARE cifs ro,noexec,nosuid,nodev,noatime,password=,nolock 0 0

這很好用!

  • 當有人通過乙太網電纜連接到路由器時,它可以看到路由器上的共享。
  • 當有人通過無線連接到路由器時,它可以看到路由器上的共享。

當有人使用乙太網電纜,然後拔下它並切換到無線時,就會出現問題:共享消失,並且無法安裝它:

mount -vvv //192.168.1.1/SHARE /home/USERNAME/Desktop/SHARE -o ro,noexec,nosuid,nodev,noatime,password=,nolock -t cifs

因為命令超時。但是,如果我們重新插入乙太網電纜並進入 GNOME2 下的“SHARE”目錄,它會自動掛載。

切換到無線後如何安裝 SHARE?是否有某種記憶體儲存 SHARE 只能通過乙太網使用?我嘗試解除安裝/掛載 SHARE,但沒有成功。

我用 bash 腳本解決了它..(簡而言之,它使用 rmmod cifs/modprobe cifs - 之後我可以在沒有超時的情況下安裝共享..ü)

#!/bin/bash

which timeout > /dev/null 2>&1; if [[ $? -ne 0 ]]; then echo -e '\nerror, no coreutils package'; exit 1; fi
which nc > /dev/null 2>&1; if [[ $? -ne 0 ]]; then echo -e '\nerror, no nc package'; exit 1; fi

# variables
   PATHTOIT="//192.168.1.1/SHARE"

# functions
function notthesame()
{
   # umount PATHTOIT
       while `mount | grep -qi $PATHTOIT`; do timeout -s 9 2 umount -l $PATHTOIT; done
       timeout -s 9 2 pkill -9 -f "SHARE"
       timeout -s 9 2 pkill -9 -f "umount -a -t cifs"
       timeout -s 9 2 pkill -9 -f "/sbin/mount.cifs"
       timeout -s 9 2 pkill -9 -f "rmmod -fw cifs"
       timeout -s 9 2 pkill -9 -f "/sbin/modprobe -q -- cifs"
       timeout -s 9 2 pkill nautilus

   # remove/add cifs kernel module
       timeout -s 9 2 rmmod -fw cifs
       timeout -s 9 2 modprobe cifs

   # mount PATHTOIT
       timeout -s 9 2 mount $PATHTOIT
}

while true; do

   # wait until we can reach the samba server
       while true; do nc -w 1 192.168.1.1 139 >& /dev/null && break && sleep 10; done

   # first sample
       REGIINTERF=`netstat -nr | awk '/0/ {print $NF}' | sort -u`

   # sleep 10
       sleep 10

   # second sample
       MILYENINTERFMOST=`netstat -nr | awk '/0/ {print $NF}' | sort -u`

   # compare the samples
       [ "${MILYENINTERFMOST}" = "${REGIINTERF}" ] || notthesame

   # if can't find mountpoint then mount it
       if ! mount | grep -qi $PATHTOIT; then notthesame; fi

done
