I am being pushed from AIX onto RHEL 6 and after our first 'chuck it on' install, I have a problem. Where is the old (okay insecure) telnet & ftp server? I know that they are probably regarded as archaic now, but the source servers do not have the SSH tools, so I've got to somehow transfer the data.
Apart from this, I have CRT from VanDyke which is very nice, but the company will not pay the upgrade fee to get the SSH version, so that's going to be a pain.
I do have a closed network, so I'm not too worried about packet snooping.
For a 20+ year support of AIX (with forays into and eventually out of Solaris, SCO Unixware, Dynix, TI-UX) & HP-UX, I'm feeling especially vulnerable as I've never been so stuck. Internet searches send me all over the place without a good target.
I don't even have the client side tools installed.
Any suggestions? (without laughing please)
If I can get the executables, I am happy to set up inetd.conf - oh no! Where's that gone now? What's all this almost empty /etc/inittab?
Despair! At least from HP-UX I've got the lvm commands such as vgdisplay.
I was aware of a reference sheet to ease conversions, but I can't seem to find that at the moment either. Maybe I'm just having a bad day.

Install the 'ftp' and 'telnet' packages for the commandline utilities, I think 'telnetd' for telnet server(unsure), and 'proftpd' for a pretty decent FTP server.
Maybe you have xinetd instead of inetd? Being a service wrapper, it's always been kind of optional -- I've personally never understood the use, some distros have it, some don't. On systems which don't, network daemons would just be system services.

True, xinetd is not that much used now a days. But it sure does a good job of make the system resources available for other use. For an example, a PXE server serving TFTP requests. Now, do you really install OSes 24x7? So there's really no use of TFTP server daemon running all the time consuming memory and doing close to nothing. But, if it's controlled by xinetd, the service only started when you get a request. A server which serves occasional ftp requests, can actually use xinetd.
Well, RHEL 6 has vsftpd as the FTP server and telnet-server package for the telnet server. To install these pacakges, you would have to make use of the installation DVD as yum repository. Let me help you with that:
1. Create a file /etc/yum.repos.d/local.repo with the following contents:
2. Create a dir /mnt/dvd and mount the DVD there
3. Use yum command to install the packages
/etc/inittab is almost empty because Sys V init has been abandoned to embrace upstart which can start multiple services simultaneously reducing the overall boot time. /etc/inittab is there just to define the default runlevel.
Hope this gets you started!
These 2 Users Gave Thanks to admin_xor For This Post:
Many thanks. Food for thought. We don't actually have original media but I think that the media images were copied onto the base server that we have cloned, so it seems to find them :-
We will have 'fun' no doubt. Am I right in my reading that csftp is on port 21 therefore will accept plain old FTP?
Thanks again,
Robin

Yes, vsftpd works on the same old ftp protocol and supports both active and passive modes. But, it's really tightly secured. That's why the name "Very Secure FTP daemon"
H Forum,

Hello all,
I am planning to deploy a configuration / auditing software package for about 100 new nodes that we are planning to install. I am hearing many good things in regards to cfengine and puppet. Can someone shed some light in regards to these solutions?
