which are the exact effects of MaxSessions
Hey. I wondered a bit which the exact effects of MaxSessions are. The documentation says: Specifies the maximum number of open sessions permitted per net? work connection. The default is 10. And it apparently seems that setting e.g. the following in sshd_config: MaxSessions 0 => no logins possible at all MaxSessions 1 =...

Exiting ssh when MaxSessions=0
Hi, I've been experimenting with MaxSessions=0 in the sshd_config and have encountered one unfortunate problem. Once the client authenticates to the server, it ceases to respond to keyboard input. At first glance, it looks like the client is in a hung state and does not time out. If port forwarding was requested on the command-line and the...

MaxSessions option in sshd_config
Hi, I need information regarding MaxSessions option in sshd_config. As i understand, it defines the maximum number of channels that can be opened at any point of time between two hosts that are connected over SSH. The default value for this option is 10 in openSSH. What all needs to be considered if i want to increase this value? Are there a...

force port redirection for list of users
...// should be sent to sshd running at port 2024 I know that we can do something like this: ssh -o ProxyCommand='ssh -W localhost:2024 cliuser at ip' otheruser@ <secadmin at 10.220.167.184>ip will take to otheruser login to port 2024 after sshd_config settings Match user cliuser MaxSessions 0 PermitOpen localhost:2024 This requires long command at the client side . Can this be made simple like ssh otheruser at ip automatically goes to port 2024 after i make some redirection at sshd_config Thanks and Regards, Sudarshan

[Bug 1517] New: ssh ControlMaster process is crashing frequently when multiplexing ssh and scp connections with error 'select: Invalid argument'
...ersion is used on the client and server, both servers are Solaris 9 Sparc platforms. The max file descriptors kernel parameter on both systems is 8192. The following parameters are set in the sshd_config (these values are overkill, but we were clutching at straws!), if we set values below 300 for MaxSessions we get 'Administratively Prohibited' authentication failures on the server side. MaxSessions 8192 MaxStartups 8192 I have attached level 9 debug. The debug always ends with 'select: Invalid argument' when the process fails.

tweaking max sessions / scaling
Other than cranking up logging to debug2, is there a way to better tune logging on a server to see if I am running into max sessions ? On FreeBSD RELENG11 I am periodically seeing connections being refused- 3way handshake not completing or completing and then FINs. Typically, I have a hundred or so connections at one time, but they can bounce up to a few hundred on occasion. Without leaving the

Multiple (multiplexed) simultaneous ssh connections - Cygwin bug?
Hello, I've see you answered a problem with simultaneous ssh connections in cygwin. The version I'm using is CYGWIN_NT-5.2 I've change the sshd_config and put the Parameter maxsessions 100 in it. But it doesn't work. Ich have still 10 limited ssh session at onen time. I need at least approx 100 to fix our specific problem. I've also tried mas_ssh_starts=100 but this prevent the ssh server to start up again. Did you have an Idea, or the right syntax for maxsessions mit f...

OpenSSH 5.1: call for testing
....com that implement statvfs(2)-like operations. * sftp(1) now has a "df" command to the sftp client that uses the statvfs at openssh.com to produce a df(1)-like display of filesystem space and inode utilisation (requires statvfs at openssh.com support on the server) * Added a MaxSessions option to sshd_config(5) to allow control of the number of multiplexed sessions supported over a single TCP connection. This allows increasing the number of allowed sessions above the previous default of 10, disabling connection multiplexing (MaxSessions=1) or disallowing login/shell/...

sshd custom shell script for specifc user
Thanks Darren, the intention to do this : allow users to access my own shell/CLI(including authentication) on port 22. their firewall settings doesnt allow anything other than port 22, so I would internally redirect to port 1023 when customuser is provided. I will try enabling logs, thanks. On Tue, Jan 31, 2017 at 5:10 AM, Darren Tucker <dtucker at zip.com.au> wrote: > On Tue, Jan 31,

Limiting simultaneous sftp downloads..
...times I could really hear my harddrive thrashing as it scanned over the disk trying to get data from both files. Now... it is quite possible that filezilla performs two logins... but it seems like it is performing the operations over the same connection. There is a sshd_config setting called "MaxSessions". I set this to one but filezilla still downloaded files in pairs simultaneously. Does anyone know if there is a facility to pull two files over one login? Is there a way to stop this? I realize that if multiple users login... then there is no way to really stop this.. but it is sad when I h...

Limit number of sessions to ALL users
I'm running 5.5p1. I want to limit the total number of ssh connections to my box, not necessarily all the connections from the same IP. I've tried setting Maxsessions, but that doesn't seem to do it. Am I missing something simple? ?
