How to set the max no of users that can telnet to a server
Hi all,
In my Server:
uera1>kcusage nstrtel
Tunable Usage / Setting
=============================================
nstrtel 240 / 1000
uera1>kcusage npty
Tunable Usage / Setting
=============================================
npty 0 / 60
uera1>kcusage nstrpty
Tunable Usage / Setting
=============================================
nstrpty 0 / 60
uera1>ll /dev/pts |wc -l
2001
uera1>
So would you pls clarify the following:
1) Max no of users that can telnet to this server.
2) If the no need to be increased what should I do?
3) role of nstrtel, npty and nstrpty towards determening the max no of users login by telnet. FYI now almost 240 user are already logged in by telnet and npty and nstrpty both set to 60.
Regards...
Kuntal

Re: How to set the max no of users that can telnet to a server
1) Max no of users that can telnet to this server.
>nstrtel â specifies the number of telnet device files the kernel can support for incoming telnet sessions
http://docs.hp.com/en/B3921-90010/nstrtel.5.html
So u can have 1000 telnet users.
240 is the usage currently.
2)If the no need to be increased what should I do?
Shutdown the telnet and start to use ssh :)
telnet is vulnerable.
3) role of nstrtel, npty and nstrpty
read below man pages
http://docs.hp.com/en/B3921-90010/npty.5.html
http://docs.hp.com/en/B3921-90010/nstrpty.5.html
