ssh连接问题

jason_teach

大家好，今天遇到了一个ssh问题，ssh居然断开连接，不让用户登陆，不管是哪个用户登录丢不可以。（普通用户  root用户都不可以）hosts.allow和host.deny都没有添加任何信息。
确定ssh配置文件没有修改过。

pam下的login文件如下：
# cat /etc/pam.d/login
#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
# pam_selinux.so close should be the first session rule
session    required     pam_selinux.so close
session    optional     pam_keyinit.so force revoke
session    required     pam_loginuid.so
session    include      system-auth
session    optional     pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session    required     pam_selinux.so open


pam下的sshd文件如下：
# cat /etc/pam.d/sshd
#%PAM-1.0
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
session    optional     pam_keyinit.so force revoke
session    include      system-auth
session    required     pam_loginuid.so

message内核信息报错如下：

secure日志如下：

Nov 15 11:25:12 localhost login: pam_unix(remote:session): session closed for user zhangshuao

我又开启了telnet服务来连接，配置完了重启以后  就连接了一次，之后在连接的话，telnet服务就拒绝连接了。


大家帮忙看看是啥问题。

chenyx

将pts/1添加到/etc/securetty看看,如果不行,注释下 /etc/pam.d/login里面的auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so行

    不行 ，试过了。

chenyx

停止ssh服务,修改下ssh端口,再启动ssh服务试试看看

    内核报错一大堆信息，你帮我看看兄弟。 我刚才重启了，现在用的telnet服务连的。我开启ssh服务  端口起不来，监听不到

这个问题就严重了.你之前做过什么操作没有?比如更新或者安装了什么软件

    我做过yum update

syre

升级内核了还是怎么了
如果升级过内核，先换回旧内核看看

chenyx

楼上说的有道理,看看是不是内核的问题

yum update后的内核信息如下：
# rpm -qa | grep kernel
kernel-2.6.18-308.el5
kernel-headers-2.6.18-371.1.2.el5
kernel-2.6.18-371.1.2.el5
# uname -r
2.6.18-371.1.2.el5

系统版本：CentOS 5.8 64位
# cat /etc/issue
CentOS release 5.8 (Final)
Kernel \r on an \m

CentOS 5.8 64位默认的内核为：
# uname -r
2.6.18-308.el5

    两个内核版本不一致了。我现在该如何做内核升级？

    这是机房的服务器，我能远程升级内核么？没有在线上做过这个内核升级降级的经验。
