The patch below (against openssh 3.2.3p1) adds a CheckMaxStartups option, defaulting to yes, to determine whether sshd calls drop_connection(). The motivation behind this is twofold. In our environment, our timesharing machines get enough incoming connections that will trigger spuriously with the default value (10 forked unauthenticated connections) as well as some significantly higher values,

Hi, I am not sure to report this as a bug. so mailing to the list. I have sshd(openssh3.5p1) server running on my router and when i run tcpjunk to that port, sshd gets killed after some time 192.168.71.1 is my sshd server and 192.168.71.4 is my client from where i send my dos attack This is the tcpjunk command i gave to the ssh server #tcpjunk -s 192.168.71.1 -p 22 -c req -i 100 req session

That makes that data accessible even without a syscall (at least the writing of the data - quering needs syscalls, right), so that can be kept up-to-date and allows a high monitoring frequency as well. Multiple instances of SSHd (on

Here is a trivial reason why I have not propagated http://bb.pgr.jp/ . Sometimes (but I suppose rarely) he reports false alarm in a few points. He'd send blames to the llvm-testresults if his master (aka I) knew he were mature. I don't also want him promoted and called as one of official buildbots. He is my pet, though, I expect he should be helpful to the developers. ...Takumi

I would like some clarification regarding the use of MaxStartups. I have always used the three colon separated value that enables the random drop capabilities, but the documentation for sshd says that MaxStartups can also take a single value which sets a max and leaves random drops off. When I try this, sshd tells me that it got an illegal integer. Looking at the code, in servconf.c it looks

Hi Group, We use a simple logon script to map drives for our users. If we put the following line: net use /delete * /yes then no drives are mapped on the workstations. If we rem it out, the script works fine. Full script below: net use /delete * /yes net use e: \\server5\peachtree net use w: \\server5\contract_maintenance net use t: \\server5\fleet net use x: \\server5\allusers net use u:

Hi All :) I need to check and possibly update openssl on my fleet of servers. I would like to avoid reboot if possible. I think that I can: - update openssl version with yum - check all daemon processes which are constantly running in the os, for example for sshd something like ldd `which sshd` | awk '/\// { print $3 }' | grep crypto | xargs strings | grep -i openssl to verify if the

I just realised that I haven't touched a centos/redhat machine in more than a couple of years. Everything I do now is Kubernetes based or using cloud services (or k8s cloud services). What about it listeroons? Is your fleet of centos boxes ever expanding or are you just taking care of a single java 6 jboss application that takes care of the companies widget stocks? How are your jobs

Let's say you have a dataframe of car trade-ins. For example, each row contains oldcar newcar qty and a typical entry could be lexus bmw 1 I put the qty column to allow for fleet purchases, where one purchase may convert multiple cars at once. I'd like to show what's going on. I could do a histogram of newcar to show the frequency each type of car is bought. If there

Hello guys! We have a lot of virtual machines and I recently tried out the migrate feature of libvirt. It works like a charm, even without shared storage, but when we try to migrate a VM under a little pressure (a HTTP server gets some 1-5 requests/sec) the migration process hangs at 99%. After we stop the stressing of the VM, the migration immediately finishes. I'm using the following
