The last week I was in Vidin, Bulgaria with no internet access and I had to fix my MTA (Postfix) at

+

host.0.buetow.org which serves E-Mail for all my customers at P. B. Labs. Good, that I do not guarantee

+

high availability on my web services (I've to do a full time job somewhere else too).

+

My first attempt to find an internet café, which was working during Christmastime, failed. However, I found with my N95 phone lots of free WLAN hotspots. The hotspots refused me logging into my server using SSH as I have configured a non-standard port for SSH for security reasons. Without knowing the costs, I used the GPRS internet access of my German phone provider (yes, I had to pay roaming fees).

With Putty for N95 and configuring Postfix with Vim and the T9 input mechanism, I managed to fix the problem. But it took half of an hour:

+
    +
  • First, getting a shell prompt
    • +
  • Second, use the "tail" command to analyse the Postfix logs
    • +
  • Third, use the "sed" command to fix a syntax error in the Postfix config
    • +
  • Fourth, restart Postfix
    • +
+

It was a pain in the ass. My next mobile phone MUST have a full QWERTY keyboard. This would have made my life lots easier. :)

+

At the moment I am in Sofia, Bulgaria. Here I can use at least an unprotected WLAN hotspot which belongs to one of the neighbours which I don’t know in person, and it is not blocking any port at all :)
