I. Background pt_chown is a setuid root support utility used by grantpt(3) to change ownership of a tty. openpty(3) is a support function in libutil which is used to obtain a pseudo-terminal. script(1) is a utility which makes a typescript of everything printed on a terminal. II. Problem Description Two issues exist in the FreeBSD pty handling. If openpty(3) is c...

Hello, I am using OpenSSH-3.8p1 on HP-UX machine with USE_POSIX_THREADS option. This is for making the kerberos credentials file to be created in the system with PAM. In OpenSSH versions 3.5 when authentication is done with pam kerberos, a /tmp/krb5cc_X_Y file is created on the server side. But the KRB5CCNAME variable is not set by default. So, after we manually set this environment variable, the

I have encountered a problem with using OpenSSH 2.3.0p1 on 64-bit HP-UX 11.00 systems. This bug does not exhibit itself on any 32-bit HP-UX 11.00 or HP-UX 10.20 systems that I have built 2.3.0p1 on. OpenSSH 2.3.0p1 was built with HPs ANSI C compiler with OpenSSL 0.9.6 and zlib 1.1.3. The problem is with the call to vhangup(2) in sshd when interactive sessions are started. The problem does not

I find that adding -D_GNU_SOURCE is useful for linux. This define enable more features from header files. First) i found that define enable declaration/definition of following methods - grantpt(...) - unlockpt(...) - ptsname(...) for device "/dev/ptmx" ( support for ptys, preferred is method openpty (...) ) Second) _GNU_SOURCE enable use of utmpx and wtmpx ( support for login recording, preferred is USE_LOGIN and syslogin_write_entry ) Three) ? at this time i don't know.

We don't currently support SVR4-style fd passing which involves I_SENDFD/I_RECVFD ioctls. I'm not sure if that might help some p platforms with privsep. Some platforms that use STREAMS ptys use a set-uid root helper to handle the privileged portions of pty creation. grantpt(3) has a bit more info. on Solaris 8 it's: /usr/lib/pt_chmod on HP-UX it's: /usr/lbin/chgpt Perhaps this may be useful to support. Someone want to investigate that?

I am aware that there have been several posts related to ssh connections hanging, i have tried to read through most of them in the archives... I am posting this in hopes that it may present something new that will further help resolve this problem. The problem i am having appears to be similar to what others have reported where after typing exit in an interactive shell the connection is not

Just today I compilied openssh-2.1.1p1 on Debian Slink and Potato both to come out with the same problem. I am compiling them with openssl-0.9.5a.. The configure line I use for openssh is below: ./configure --sysconfdir=/etc/ssh --prefix=/usr --with-ssl-dir=../openssl-0.9.5a So I compile, do a make install restart the sshd daemon and everything seems fine. Then when I do a w at the prompt
