G''Day Folks, I''ve finally typed up my classic DTrace demo, which I use to introduce people to DTrace (I delivered this at SOSUG#1), http://www.brendangregg.com/DTrace/dtracevstruss.html Here I create a fault and show the difficulty in analysing it using previous tools. Then I compare the impact of analysing the problem using both DTrace and truss. DTrace wins (a lot!).

I am running a very simple multithreaded program (TestThread.C) which calls gethostbyname_r in several threads. My analysis of this program with both truss and DTrace suggest that is has a small leak. However, if I alter the program to have many more threads and run for a lot longer it never runs out of memory and does not carry on growing. Can anybody explain what I am missing in my analysis or

On my solaris 2.6 box, I get ssh moni ld.so.1: ssh: fatal: libz.so: open failed: No such file or directory Killed while as root, I have no problem.

This morning, I noticed in my security email, that my entire /usr/bin directory had setuid diff's set on them. I think I've been hacked. So I installed chkrootkit from ports and ran it. It showed not infected for everything, except NETSTAT. NETSTAT showed infected... I ran chkrootkit for another machine (at my office), and it showed not infected for everything. Both machines are

Hi, i am experiencing a problem with ssh 3.0.2.p1 running on Solaris 2.8. Everything works fine with local users (i.e. with local passwd and shadow entries). With LDAP authenticated users, i obtain: treno at tao[!] -> ssh -v Segmentation Fault (core dumped) The probem is the same with 2.x releases. Thank you, Roberto Bertucci

Hi: I''m running Indiana (OpenSolaris developer preview) under parallels in OS X 10.5.1. I can consistently get Solaris to hang. Doing a dtrace -n pid\$target::malloc:entry''{@=count()}'' -c ls will consistently hang Solaris. Basically doing anything with PID provider with the -c option seems to hangs Solaris. Only way to recover is to stop and start Parallels desktop.

Hi all, I am installing a zone onto two different V445s running S10U4 and the zones are taking hours to install (about 1000 packages), that is, the problem is identical on both systems. A bit of trussing and dtracing has shown that the pkginstalls being run by the zoneadm install are making door_call calls to nscd that are taking very long, so far observed to be 5 to 40 seconds, but always in times divisible by 5 seconds (5, 10, 15, etc.), leading to the thought that it is one or more name service...

We have been having a problem with sshd on our shell server. This has been happening since March 4, 2003 or before IIRC. Initially I thought the next OS upgrade, to 4.8 would fix this. I am accustomed to haveing little things go away in a month or two. I think we jumped to 4.7-STABLE on Feb 28, 2003. Some exploit fix wasn't being MFSd to RELENG_4_7 fast enough for my nerves (cvsd?). It

OK, so this may be a little off-topic, but here goes: The reason I switched to OpenSolaris was primarily to take advantage of ZFS''s features when storing my digital imaging collection. I switched from a pretty stock Linux setup, but it left me at one disadvantage. I had been using inotify under Linux to trigger a series of Ruby scripts that would do all the basic ingestion/setup for

I'm really scratching my head on this one. The server is running OpenSSH 5.1p1 on Solaris 9. The authentication is via PAM if that matters. # grep X11 sshd_config | sed '/^#/D' X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost yes # Now I attach to my 'master' sshd and follow all children to look for any evidence of "DISPLAY": # truss -f -a -e -p 14923

Hi Samba world, Have been struggling with this for the past 10 days, we are running Samba 3.0.22 on VCS zone, we have end users saving files onto Samba mapped drive, and complained that it 5mins to save 300 files, now it takes 30 mins. There is recently a change in the topology. Before Enduser ----------- samba mapped -------------- server (local attached storage)

To all: While updating our Samba installation from 2.2.5 to 3.0.25b, I found that Samba's performance was severely degraded. A 1 gig test file with random text in it would take about 2:15 to copy using the old 2.2.5 smbd, but the same file would take 5-6 minutes to copy with a freshly compiled version. I ran truss on smbd while the file copy was taking place, and found that the utime()

Again, apologies for my ignorance - are you suggesting that if the NUT application was built against openusb this would probably be fixed? If so I'm happy to give this a try - any idea how can I tell NUT to build against openusb instead of libusb?

Heya, I have compiled and installed OpenSSH on a Solaris/Sparc machine and whenever I try to start any of the ssh programs I get "fatal: PRNG initialisation failed -- exiting" Now, I have looked through the mailing lists and have seen some mention that this indicates it can't open the ssh_prng_cmds file, which entropy.c also seems to indicate the problem is. However, this snippet
