Hello,

I have a firewall appliance (SnapGear SG560) which appears to be going offline intermittently and I'm trying to do some troubleshooting. I'd like to confirm that the filesystem has adequate free disk space

The Linux version is 2.4.31-uc0, gcc version 3.3.2

There is a diskutil tool which produces a report, but I haven't been able to find a guide on the Net to interpret the diskutil results so hoping I can get some assistance either on the results or where I might find a guide.

The report for root is as follows:
blocks 4096
bfree 0
inodes 739
ifree 0

I'm concerned that bfree 0 / ifree 0 might indicate no free space.

However there are other partitions (ram1, ram2) so perhaps this is normal. Unfortunately I don't have another device to compare with.

Thanks

VW

Does man diskutil on the device give you any further info on interpreting the results?

Plenty of manpages online - most say Apple, but for something that old, probably BSD.

man: bad command or file name

I'm not a Unix expert by any means, but the CLI environment seems to be limited. So far none of the commands that I've tried seem to support any switches.

I've found df command, but again it doesn't appear to accept any switches

I'll have a look at man pages online, thanks.

It looks as if Snapgear was bought out by McAfee and the firewall product range rebranded as UTM Firewall.

At a pinch you could try contacting McAfee directly or through their (rather inactive) community page at https://community.mcafee.com/communi...k/utm_firewall, although they do say that the SG560 went EOL in 2013.

Maybe it's just busybox plus company add-ons. I found a manual online that has a chapter for CLI commands and lists the devices that support that command. For example fdisk is listed, but not for the SG560. Interestingly, diskutil isn't mentioned at all. - well actually it is; as "report/diskutil"The GCC mentioned is "Global Control Centre", not your everyday gcc as we think of it.

Unfortunately you can no longer obtain vendor support for the Snapgear.

When I was trying to figure out whether maybe the unit had ran out of space, I also had a look at the logs and I could see some unauthorised attempted connections via SSH. So I made some changes to prevent that and so far since then the unit has been behaving itself. Need to wait a few more days, but perhaps some of these attempts were causing the issue I have been observing. It's been a good unit and I don't want to chuck it unless I'm sure it's cactus.
