Working with interfaces in Solaris is pretty much the same as in Linux - you've got ifconfig, netstat,route. It looks in output a bit different but if you're used to the *BSD way of things you'll find yourself at home. So the most basic thing follows - bring interface up, assign …
Of course you know what the good password should be - random letters including capitals, peppered with numbers and enhanced with printable control characters. The only problem with these recommendations is that there are very few people in the world that can memorize such incomprehensible sequence of chars. So if someone …
As a follow up to yesterday's post I thought it would be interesting to know statistics of the usernames used in those brute force probes. Find below awk/sed script to get usernames for failed ssh login attempts from OpenSSH daemon and sort it for statistics. Also I attach the …

This comes from unpleasant experience of mine. One of my clients’ domain records (MX for the case involved) was mistakenly changed. While it was a human error and trying to fix humans is rolling the rock of Sisyphus,damage would be much lesser had I known about the change immediately …
Do we need to fix all the problems all the time ? My answer is no. Also I believe in good solution today and dismiss ideal solutions tomorrow. Let me show this on the real case with one of the clients. Client has Checkpoint, lots of Checkpoint, just heaps of it …
To create VLAN in Solaris you have to first decide where the Physical Point of Attachment (PPA) will be. In other words you have to attach VLAN to some physical interface on the server , as of now interface types that support VLANs are: - ce - bge - xge - e1000g After you decided …
