Normally I try to solve my own problems, and "Red Hat in 24 Hours" has most of what I need to know. I'm a relative newbie to Linux, having installed it on my old Celeron 850 late last year. The latest problem has gone beyond the book, and I suspect that we can't go outside Australia for a solution. My ISP has indicated that the problem lies with Telstra, as my hardware and their servers have not undergone any changes which would cause the problems I'm experiencing. I'm writing this from a Windows machine. Since 1/9 I haven't been able to send or receive any mail on the Red Hat machine. Has anyone in the SLUG been affected by Telstra upgrades to their ADSL lines? On the Windows machine I had to download Dr.TCP and make some changes to the settings. This was to limit the packet size going through the modem/router, for reasons best understood by the techos. My ISP - iinet - gave me some settings to change on the Red Hat machine through the Terminal and Text Editor, which accepted, but I still can't send or receive any mail. I live in the Canberra/Queanbeyan area. Below is the mail item which might help explain things better. I have Nedit, not Pico on my machine, the mtu value was 1400, not 1420, and <CTRL-S> was used to save the changes.
- Hi John,
- As a follow on from our phone conversation this morning, please find below how to fix the linux machines permanently.
- 1. First, log in as root.
- 2. At a terminal prompt type in the following:
- pico /etc/rc.local
- And press Enter
- 3. You should see an editor screen appear. Use the arrow keys on the keyboard to go to the very bottom of the file.
- 4. Type the following at the bottom of the file:
- ifconfig eth0 mtu 1420
- 5. Then press <CTRL-X> (hold down the Ctrl key on your keyboard, then press the letter X)
- 6. Press 'y' to confirm the changes when prompted to Save modified buffer.
- 7. You should now be able to reboot the linux machine and the changes will be permanent.
- Regards
- Jason
