再问：20.04无法访问无线路由器上的U盘

[男菜鸟]

这个问题不解决，我就无法使用20.04了
因为这个路由器上的U盘内容是整个局域网共享的，不能读出内容就无法工作了。
这个路由器是华硕2019年的产品（RT-AC1200GU），还会使用SMB1版本吗？查了全部资料和它的后台log，也看不出它的SMB版本

[astolia]

RT-AC1200GU在2016年就上市了。而且这种路由器系统带个老版本的samba再正常不过了。
你可以尝试把 client min protocol = CORE 里面的CORE换成NT1试试
再不行就加个client max protocol，值设置成和client min protocol一样。我记得以前遇到过某个版本的samba在协议版本协商的时候有问题

[男菜鸟]

试验在 /etc/samba/smb.conf 的 [global] 里，先后加入
client min protocol = NT1
client max protocol = NT1

重启电脑后，情况没有改变，可以进入U盘，及子目录，但是最后一层的文件，doc,xls,ppt,pdf....图标都是
和子目录一样，而且无法识别打开相应的应用程序

你把現在的 /etc/samba/smb.conf 再貼上來一次。

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
server string = %h server (Samba, Ubuntu)

client min protocol = NT1
client max protocol = NT1

#max protocol = smb2

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
max log size = 1000

# We want Samba to only log to /var/log/samba/log.{smbd,nmbd}.
# Append syslog@1 if you want important messages to be sent to syslog too.
logging = file

# Do something sensible when Samba crashes: mail the admin a backtrace
panic action = /usr/share/samba/panic-action %d


####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller".
#
# Most people will want "standalone server" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.
server role = standalone server

obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
map to guest = bad user

########## Domains ###########

# The following settings only takes effect if 'server role = primary
# classic domain controller', 'server role = backup domain controller'
# or 'domain logons' is set

# profile directory from the client point of view) The following
# required a [profiles] share to be setup on the samba server (see
# below)
; logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
# logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)

# logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
; logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the
# SAMR RPC pipe.
# The following assumes a "machines" group exists on the system
; add machine script = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

client min protocol = NT1
client max protocol = NT1

有bug报告了 https://bugs.launchpad.net/ubuntu/+sour ... ug/1872476
你尝试一下里面提到的临时解决方案，看看有没有效

代码： 全选

sudo add-apt-repository ppa:sergiodj/samba-bug1872476-v2
sudo apt update
sudo apt upgrade

你可以把client max protocol = NT1这行删掉了。免得以后连不上用新版协议的samba服务

[男菜鸟]

谢谢版主！

运行后问题部分解决！经上面命令处理后，20.04UBT可以在文件管理器里打开路由器上U盘共享的文件，并且准确
识别doc xls ppt txt....，打开相应的程序！

剩余的问题是共享U盘，在路由器上只能“允许访客进入”，不能设置用户，设置用户即使名称密码准确，也不能打开U盘，看不到内容。所以现在只能允许访客进入，有的安全风险。
