On machine #1, where I just installed telnet an hour or so ago, and where it ran but failed to connect, I've just tried again with a new target -- and suddenly bash doesn't see telnet any more! ===== ===== ===== ===== [btth@Hbsk2 ~]$ telnet 192.168.a.b 631 Trying 192.168.a.b... telnet: connect to address 192.168.a.b: No route to host [btth@Hbsk2 ~]$ ssh 192.168.a.b btth@xxxxxxxxxxx's password: Last login: Thu Oct 30 09:51:51 2008 from 192.168.a.q [btth@Msgv ~]$ telnet 192.168.a.c 631 -bash: telnet: command not found [btth@Msgv ~]$ telnet 192.168.a.c 631 -bash: telnet: command not found [btth@Msgv ~]$ telnet 192.168.a.c 631 -bash: telnet: command not found [btth@Msgv ~]$ ===== ===== ===== ===== In between those, I ran rpm -q telnet on a different gnome- terminal tab, and then "yum install telnet" again on a root tab.
