Topic: dropped internet connection

[John]

For some reason internet connection is dropped every day (every 24 h). It's sme 5.5 with latest update (fresh installation).I'm using cable isp.
I've had it running for over 6 month without any problem, than it started dropping connection. As I've made a lot of changed to it, reinstalled it - same thing.
 I've looked in to the message logs but nothing there. I did notice that ip address was requested every 30 min - Is that normal?
What is the name of the log file that contains nat related messages.
Only thing that I have added to this fresh installation is services add-on - to disable mail server and samba services.

Thank you in advance,
John

Hey, I am experiencing the same problems. I have been using e-smith since 4.1.2 with out problems. But now many problems. I am including my issue .

-----------------------

Problem: e-smith box loses Internet connectivity at what appears to be regular intervals. Internal LAN is not affected.

Hardware: PC server, AMD K6-2 500Mhz, 256 M ram, 20G IDE drive, 2- AOpen Real-Tek 8139 NICs.

e-smith versions: this has occurred with fresh installs of  versions; 5.1.2, 5.5, 5.6b7 ,patched and unpatched.

ISP: Cox Communications, residential DHCP based, cable connectivity. The use of username /password is not in use. They do not use BOOTP style MAC address binding. I called tech support to confirm that their  system was not experiencing any problems.

Log Files: Within the “messages” log from the Server Manager, my server appears to request a new DHCP address from the DHCP server from Cox Cable Internet. However the address is not given out, a release does not take place therefore complete negotiation process fails.

Workaround: A Bug report for this issue, ISP DHCP response corrupts resolver configuration,  or one very similar has been recognized  and is at http://e-smith.org/bugs/index.php3?op=showBug&bugID=67

I use the  workaround below from the bugs page:

# drop the external link - note therefore that you can't perform the
# fix remotely using this procedure

  /sbin/ifdown eth1

# Replace /etc/resolv.conf with the correct contents

  /sbin/e-smith/expand-template /etc/resolv.conf


# Now bring the external interface back up
  /sbin/ifup eth1

Troubleshooting: When this began I was using a fresh install of 5.6b7. After the first occurance I rebooted and didn’t think much of it. The second time, rebooted and checke the bugs page where I found a similar DHCP on the external interface issue. I applied the workaround with success.

Then occurred a third time, so this time I replaced the NICs. Approximately 30 minutes later the issue happened again.

I reinstalled with 5.12 on the same hardware. Issue was not resolved, it happened again. The workaround resolved a new DHCP address and allowed Internet connectivity without a reboot.

I applied the latest patches for 5.1.2, yet the occurrences continued.

So, I reinstalled with 5.5, which was the current permanent fix for the, ISP DHCP response corrupts resolver configuration , bug.

Did not work. Then I applied all of the 5.5 patches including the non-Blades RPMs.

Did not work. All of the above and the issue was not resolved.

So now I am using a Floppy Disc based Linux router/firewall. This is the link, http://bbiagent.net/en/index.html .

Ok, I am using all the same hardware except the OS has changed, BBIagent floppy router/firewall. I have had NO problems using BBIagent router on the same hardware. Been up more than 18 hours with no interruptions.
