this idea i have, too.
I have also tried
radtest -t mschap "test\\radius" radius localhost 1 testing123 radtest -t mschap 'test\\radius' radius localhost 1 testing123 radtest -t mschap 'test\radius' radius localhost 1 testing123
Ah, there's still not enough escaping: root@radtest:~# radtest -t mschap 'test\\radius' radius localhost 1 testing123 Sent Access-Request Id 15 from 0.0.0.0:60124 to 127.0.0.1:1812 length 136 User-Name = "test\radius" By this stage, your '\ \ r' has still become '\r' and radclient rakes this as CR. So it looks like there is another level of unescaping taking place inside radtest (which is a shell script) So you need *four* backslashes, which you can get in single quotes like this: root@radtest:~# radtest -t mschap 'test\\\\radius' radius localhost 1 testing123 Sent Access-Request Id 201 from 0.0.0.0:36290 to 127.0.0.1:1812 length 137 User-Name = "test\\radius" (Without quotes, or in double-quotes, you would need 8 backslashes!) Now you can see that radclient receives "test\\radius" which it should interpret as t e s t \ r a d i u s And at last, tcpdump confirms this: # tcpdump -i lo -nn -s0 -v -X udp port 1812 tcpdump: listening on lo, link-type EN10MB (Ethernet), capture size 262144 bytes 11:05:05.119847 IP (tos 0x0, ttl 64, id 19098, offset 0, flags [none], proto UDP (17), length 165) 127.0.0.1.53576 > 127.0.0.1.1812: RADIUS, length: 137 Access-Request (1), id: 0x06, Authenticator: e03656048448efdd3e6345a719fb218f *User-Name Attribute (1), length: 13, Value: test\radius* NAS-IP-Address Attribute (4), length: 6, Value: 127.0.1.1 NAS-Port Attribute (5), length: 6, Value: 1 Message-Authenticator Attribute (80), length: 18, Value: ..g..){.m...%,.)
