Hi.
For a long time I am puzzled why, when internet connection is gone
(beyond first router, outside of subnet) SSH (and telnet?) connection is
drastically slowed.
Same behavior, but less impacted is observed when system boots without
working internet connection, and I am not sure, but I think even access
to SAMBA fileshares can be/is affected. Affected systems are mostly
production servers, and too spaced apart in time to be able to point a
finger in something I am doing wrong.
I have not had time to gather more facts, I always forget/don;t have
time, so I will only focus on definite SSH issue on CentOS 6.3, although
I have seen same with 5.x.
1 server in question is set in following maner:
[root@chiron ~]# cat /etc/networks
default 0.0.0.0
loopback 127.0.0.0
link-local 169.254.0.0
[root@chiron ~]# cat /etc/sysconfig/network
NETWORKING=yes
NTPSERVERARGS=iburst
HOSTNAME=chiron.example.com
[root@chiron ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4 chiron.example.com chiron
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
chiron.example.com chiron
Does it have anything to do with /etc/hosts file not having row with
used IP address, or is problem somewhere else?
Searching the net gives too much irrelevant links, and all I need it to
be pointed in the right direction.
