I hate doing that as it ties a machine up for hours by saturating its network connection. -- MJR

I can't get local admins to agree to that, as it involves doing it at the network rack because the machines need to talk 100Mbps to each other. Sad, but true. Maybe after the next hack... -- MJR

Firewall testing
by Adam Bower 05 Jun '01

05 Jun '01

Hi all, I just got around to updating my firewall to use IPtables and was wondering how could I check that I havn't left any big hole in it? I know about online port-scanners but how do I know if they are reliable? (indeed you can ssh to my machine and http from the outside world but the online ones I just tried seemed to ignore this little fact) I short does anyone know a good online portscanner or is anyone willing to run NMAP or nessus against me? Thanks Adam -- This message is Copyleft - all rights reversed Adam

One thing Debian *still* has my respect for is that its "stable" really is, while still having security updates. > If you want I can do a 10 minute demo at the barbeque on how to make a > machine install updates automatically if it will encourage people to do > this...

This would be good, although "apt-get update ; apt-get upgrade" variations are 5 minutes up front and then just looking over the output of the cron job... Seeing as this is pretty much a "misc" thread: I have discovered a RedHat 6.1 machine under my control. How do I upgrade it to 7.1? If it's a nuke and start again, I'll use Debian instead, as time is short, but as time is short, I'm quite happy to leave it as RedHat if there's an upgrade path. -- MJR

Wasn't fun and certainly wasn't easy. However about 4 weeks after it went live some bright spark noticed it was now possible to get a full picture of the network and its nodes, names and all sorts of other stuff (because of the newly functioning MS SNMP services) across the internet by issuing an SNMP Walk against the public MIB on the firewall's IP (which had been configured for SNMP traffic due to this new agent reporting to the sysadmin remotely!) NB Anyone who hasn't a clue what I'm talking about try the following : 1) if you can, get the MS platform SDK and install the snmptool component. (there are tons of free SNMP tools about on the net if you can't get this... a quick lycos search should get you some) 2) Ensure you have the SNMP Service active (WIN NT... dunno about other flavours though I know you can have SNMP installed) 3) try the following command (other tools should be very similar in usage) snmptool walk 127.0.0.1 public 1 Here is the output from my work machine : -----SNIP----- SnmpTool - Simple Network Management Protocol Tool for Win32 Performing branch walk starting at OID 1.3.6.1.2.1.1 Name: system.sysDescr.0 OID: 1.3.6.1.2.1.1.1.0 Type: OCTET STRING Length: 135 Value: Hardware: x86 Family 6 Model 5 Stepping 2 AT/AT COMPATIBLE - Software: Windows NT Version 4.0 (Build Number: 1381 Uniprocessor Free ) Name: system.sysObjectID.0 OID: 1.3.6.1.2.1.1.2.0 Type: OBJECT IDENTIFIER Length: 12 Value: 1.3.6.1.4.1.311.1.1.3.1.1 Name: system.sysUpTime.0 OID: 1.3.6.1.2.1.1.3.0 Type: TimeTicks Value: 6914 Name: system.sysContact.0 OID: 1.3.6.1.2.1.1.4.0 Type: OCTET STRING Length: 14 Value: Earl Brannigan Name: system.sysName.0 OID: 1.3.6.1.2.1.1.5.0 Type: OCTET STRING Length: 6 Value: APOLLO Name: system.sysLocation.0 OID: 1.3.6.1.2.1.1.6.0 Type: OCTET STRING Length: 13 Value: In the Window Name: system.sysServices.0 OID: 1.3.6.1.2.1.1.7.0 Type: INTEGER Value: 79 End of MIB branch -----SNIP----- Try the following command ... very interesting if you are connected to a network .... snmptool walk 127.0.0.1 public .1.3 (note the point in front of the 1 - important) For my machine I can see the shared drives, mapped network drives, ethernet adapters, the names/ip addresses of every other machine on my subnet......and all with little effort. It doesn't take einstein to figure out how useful some of this info is to the potential hacker.... BTW, try this against a few web servers when connected to the net....you could be intrigued. > > I will also bring along some good info in pdf/html/text format for further > > reading for anyone who is interested. > > We could upload this to the web site on the day, too?
