求教：exceed客户端无法访问xdm服务

zhanguoz

请高手指点：
我原来在redhat as3.0上配置的xdm服务，exceed客户端能连接，可最近几天出现故障，xdm-errors显示：“xdm error (pid 4021): error 98 binding socket address 177
xdm info (pid 4021): Couldn't connect to PRNGD socket "/tmp/entropy": No such file or directory

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.


If you encounter a server crash, please report the problem by filing a bug
report in the XFree86.org bugzilla at http://bugs.xfree86.org and/or Red Hat
bugzilla at http://bugzilla.redhat.com/bugzilla. When filing your report, it
is very important that you explain your problem in as much detail as possible,
and include a complete description on how to reproduce the problem. After
submitting the bug report, attach the following files as uncompressed
individual file attachments using the bugzilla file attachment feature:
- Kernel log file: /var/log/messages

xdm error (pid 4021): server unexpectedly died
xdm error (pid 4021): Server for display :0 can't be started, session disabled

我删除/tmp/.X0-lock和/tmp/.x11-unix然后重启却没有用，哪位高手可以指点迷津，谢谢!
