RE: [opensuse] Server cannot connect to itself

They are on a UPS, but it's an overloaded UPS (we're in the process of
some serious hardware upgrades).  One of them did have a bad NIC, but it
was after I replaced the NIC that the problems started.

After some serious investigation last night, I found that some of the
files in /etc/sysconfig/network got scrambled.  Once I fixed this
everything came up and started working properly again.

[opensuse] Server cannot connect to itself

2007-04-23 Thread Drew Burchett
I have two servers running on identical hardware.  They are both running
Suse Linux 10.1.  One is running Bind 9.3.2 and the other is running
Apache 2.1 and MySQL 5.0.  Today when I came in, the servers had been
restarted and the network interfaces did not come up (I'm pretty sure it
was a power outage over the weekend).  I shut the machines down and
started them back up and everything seemed to come back up and run
correctly.  I can access Bind, Apache and Mysql from remote machines and
everything works perfectly.  However, when I attempt to access one of
these services from the machine that it resides on using its IP address,
it will not respond.  I can access mysql locally by connecting to
localhost rather than the machine's IP address (no, that isn't a
permissions issue, I've thoroughly checked that).  Bind and apache did
not bind to 127.0.0.1, so I can't say if it works the same way or not.
If I perform netstat -aln on one of the machines, it shows that all the
proper ports are bound.  One thing that I did notice that seemed rather
odd was that when I attempted to connect to mysql via IP address and did
a netstat -aln at the same time, it showed the connection with a status
of SYN_SENT.  The status never changed until the connection broke.

I have not installed any updates or patches to any of these machines in
several months, so I can't imagine what has happened.  I also have two
other identical machines, one running MailScanner and another running
Bind that are working correctly.  They are accepting connections from
themselves without any problem.

Can anyone give me any idea where to start troubleshooting this?

Did the nics get found and assigned in the same order as originally set up?
How are IPs assigned? Static or Dynamic?
What are you using as a firewall?
